Advance preparation of action courses toward emotional stimuli is an effective means to regulate impulsive emotional behavior. Our experiment shows that performing intentional acts of approach and avoidance in an evaluation task influences the unintended activation of approach and avoidance tendencies in another task in which stimulus valence is irrelevant. For the evaluation-relevant blocks, participants received either congruent (positive-approach, negative-avoidance) or incongruent (positive-avoidance, negative-approach) mapping instructions. In the evaluation-irrelevant blocks, approach- and avoidance-related lever movements were selected in response to a stimulus feature other than valence (affective Simon task). Response mapping in the evaluation task influenced performance in the evaluation-irrelevant task: An enhanced affective Simon effect was observed with congruent mapping instructions; in contrast, the effect was reversed when the evaluation task required incongruent responses. Thus, action instructions toward affective stimuli received in one task determined affective response tendencies in another task where these instructions were not in effect. These findings suggest that intentionally prepared short-term links between affective valence and motor responses elicit associated responses without a deliberate act of will, operating like a "prepared reflex."

The purposes of the present study were (a) to use both a relational-anxiety Go/No-Go Association Task (GNAT) and an avoidance-of-intimacy GNAT in order to assess an implicit Internal Working Model (IWM) of attachment; (b) to verify the effects of both measured implicit relational anxiety and implicit avoidance of intimacy on information processing. The implicit IWM measured by GNAT differed from the explicit IWM measured by questionnaires in terms of the effects on information processing. In particular, in subliminal priming tasks involving with others, implicit avoidance of intimacy predicted accelerated response times with negative stimulus words about attachment. Moreover, after subliminally priming stimulus words about self, implicit relational anxiety predicted delayed response times with negative stimulus words about attachment.

How does achievement motivation influence mental effort mobilization? Physiological evidence of deteriorative effects of negative affects on the level of engagement.

PubMed

Capa, Rémi L; Audiffren, Michel

2009-12-01

We tested whether the effect of achievement motivation on effort is modulated by two possible factors of the motivational intensity theory (Wright and Kirby, 2001): perceived difficulty and maximally justified effort. Approach-driven (N=16) and avoidance-driven (N=16) participants were first instructed to perform a reaction time task to the best of their abilities. Next, the participants were instructed to consistently beat their performance standard established in the first condition. Approach-driven participants showed a stronger decrease of midfrequency band of heart rate variability, which was used as an index of mental effort, than avoidance-driven participants in the second instruction condition. Moreover, avoidance-driven participants showed a higher corrugator supercilii reactivity, which was used as an index of negative affects, than approach-driven participants in the second instruction condition. No difference of perceived difficulty between groups was observed. Results suggested that avoidance-driven participants developed negative affects in the second instruction condition decreasing the maximally justified effort and their level of engagement.

Mediators of Outcome in Complicated Grief Treatment.

PubMed

Glickman, Kim; Shear, M Katherine; Wall, Melanie M

2017-07-01

In this study, we examined the mechanisms of action of complicated grief treatment (CGT), an efficacious psychotherapy for complicated grief. We explored 3 putative mediators (guilt/self-blame related to the deceased, negative thoughts about the future, and avoidance) among treatment completers assigned to either CGT (n = 35) or interpersonal psychotherapy (n = 34) in a previously reported randomized controlled trial. Antidepressant use was examined as a moderator of mediation effects. A reduction in guilt/self-blame, negative thoughts about the future, and avoidance behavior each mediated the relationship between treatment group and complicated grief outcomes. Reduction in avoidance emerged as an independent mediator after controlling for all mediators. Reducing avoidance of situations and emotions connected to the loss seems to be a key mechanism of change in CGT. Revising counterfactual thinking around troubling aspects of the death may also play a role in facilitating effective adaptation to loss. © 2016 Wiley Periodicals, Inc.

Emotionality and self-regulation, threat appraisal, and coping in children of divorce.

PubMed

Lengua, L J; Sandler, I N; West, S G; Wolchik, S A; Curran, P J

1999-01-01

A model of the effects of children's temperament (negative and positive emotionality, impulsivity and attention focusing) on post-divorce threat appraisals, coping (active and avoidant), and psychological symptoms (depression and conduct problems) was investigated. The study utilized a sample of 223 mothers and children (ages 9 to 12 years) who had experienced divorce within the last two years. Evidence was found of direct effects of child-report negative emotionality on children's threat perceptions and of child-report positive emotionality and impulsivity on children's coping. Indirect effects of negative emotionality on active and avoidant coping through threat appraisal were found. Direct effects of the temperament variables on symptoms were also found. Cross group analyses indicated that the models were robust to age differences, but gender differences were found in the relation between negative emotionality and depression. The results of this study indicate that temperament and threat appraisals are important predictors of children's post-divorce symptoms, and that temperament is a predictor of children's appraisal and coping process.

Exploring the relationship between positive and negative emotional avoidance and anxiety symptom severity: the moderating role of attentional control.

PubMed

Bardeen, Joseph R; Tull, Matthew T; Stevens, Erin N; Gratz, Kim L

2014-09-01

Emotional avoidance has been found to be associated with higher levels of anxiety. However, no research to date has differentiated between the avoidance of positive and negative emotions in relation to anxiety. Additionally, no studies have examined the extent to which attentional control moderates the relation between the avoidance of emotions and anxiety. Thus, the purpose of this study was to (a) clarify relations between both positive and negative emotional avoidance and anxiety, and (b) examine attentional control as a moderator of the relations between both positive and negative emotional avoidance and anxiety. A community sample of adults (N = 93) completed a series of questionnaires, as well as a laboratory-based measure of attentional control. Greater avoidance of both positive and negative emotions was associated with higher levels of anxiety. Additionally, attentional control moderated the relationship between negative (but not positive) emotional avoidance and anxiety. Specifically, the avoidance of negative emotions was associated with higher levels of anxiety for those with lower attentional control. Limitations include a cross-sectional design, use of self-report measures, and the examination of hypotheses within a non-clinical sample. Findings are consistent with a growing body of research demonstrating the moderating role of attentional control in the relation between risk factors and negative outcomes. Findings also suggest that empirically-based treatment approaches that contain attention-based components may be beneficial for emotionally avoidant individuals with poor attentional control abilities.

2017-03-01

Studies have demonstrated inefficient use of antecedent-focused emotion regulation strategies in children with ADHD attention-deficit/hyperactivity disorder (ADHD). In the current study we tested for the first time if ADHD is also associated with difficulties in response-focused strategies by measuring the ability to override action tendencies induced by emotional information. Performance data on a computer-based approach-avoidance paradigm of 28 children with ADHD and 38 typically developing children between 8 and 15 years of age were analyzed, by comparing a congruent condition in which they were instructed to approach positive and avoid negative pictures and an incongruent condition where they had to override these automatic reactions and approach negative and avoid positive pictures. Children also rated the valence and salience of the pictures. Children with ADHD and typically developing children rated the emotional valence of the pictures appropriately and similarly, while positive pictures were rated as more arousing by children with ADHD. Solid congruency effects were found indicating that the task measured response-focused emotion regulation; however groups did not differ in this respect. Our findings do not support a deficit in emotion regulation in ADHD in terms of the ability to override natural tendencies to approach positive and avoid negative pictures.

Approach/avoidance motivation, message framing and skin cancer prevention: a test of the congruency hypothesis.

PubMed

Hevey, David; Dolan, Michelle

2014-08-01

The congruency hypothesis posits that approach-orientated individuals are persuaded to engage in prevention behaviours by positively framed messages; conversely, negatively framed messages are more persuasive in encouraging those who are avoidance-orientated. A 2 (frame: loss vs gain) × 2 (motivation: avoidance vs approach) design examined the effects of skin cancer information on sun-protective intentions and free sunscreen sample requests among 533 young adults. Gain-framed messages had the strongest effect on sun-protective intentions for approach-oriented individuals, whereas loss-framed messages had the strongest effect on avoidance-oriented individuals. Message framing effects on precautionary sun behaviour intentions were moderated by motivational differences. © The Author(s) 2013.

Social approach and avoidance behaviour for negative emotions is modulated by endogenous oxytocin and paranoia in schizophrenia.

2014-11-30

Patients with schizophrenia suffer from dysfunctional social behaviour. Social approach and avoidance (AA) has been associated with motor responses, as the affective valence and gaze direction of facial stimuli can bias push and pull motor tendencies. The aim of this study was to investigate the role of endogenous oxytocin in social AA behaviour in schizophrenia. Basal plasma oxytocin levels were collected from 28 patients who were then given a joystick-based Approach-Avoidance Task (AAT). Reaction times were recorded and AAT effect scores calculated for responses to happy and angry faces, which either had direct or averted gaze. Individual differences in basal oxytocin had a significant relationship with AAT responses, and patients with higher levels of oxytocin tended to avoid angry faces more. Furthermore, greater avoidance of angry faces was correlated with more severe psychotic (positive and general) symptoms and greater paranoia. This suggests that the endogenous effects of oxytocin may be specific to the interpretation of negative threatening emotions in schizophrenia patients, and also provides evidence that psychotic symptoms and paranoia can impact on social AA behaviour by heightening threat avoidance.

Dehydration is one of the main problems associated to endurance sports. In order to avoid the negative effects of dehydration athletes tend to drink well above their current needs. The negative effect of drinking too much fluid is hyponatremia. Hyponatremia is defined as a plasma sodium concentration lower than 135 mmol/L. Hyponatremia is the first cause of severe illness in ultraendurance sports and has been associated with sudden death. In this article, we analyze the causes, consequences, associated factors, therapeutic treatment and prevention of ultraendurance sports-associated hyponatremia. It is concluded that an adequate fluid ingestion is the best method to avoid hyponatremia. There is not conclusive data about the amount and necessity of sodium supplementation to avoid hyponatremia. However, it might be that it is not necessary to ingest additional sodium to prevent the development of hyponatremia in athletes who only partially replace their fluid losses during prolonged exercise.

Age and motivation predict gaze behavior for facial expressions.

2011-09-01

This study investigated age-related differences between younger (M = 25.52 years) and older (M = 70.51 years) adults in avoidance motivation and the influence of avoidance motivation on gaze preferences for happy, neutral, and angry faces. In line with the hypothesis of reduced negativity effect later in life, older adults avoided angry faces and (to a lesser degree) preferred happy faces more than younger adults did. This effect cannot be explained by age-related changes in dispositional motivation. Irrespective of age, avoidance motivation predicted gaze behavior towards emotional faces. The study demonstrates the importance of interindividual differences beyond young adulthood.

Coping and negative appraisal as mediators between control beliefs and psychological symptoms in children of divorce.

PubMed

Sandler, I N; Kim-Bae, L S; MacKinnon, D

2000-09-01

Examined control beliefs of children of divorce as predictors of their coping, negative appraisals for stressful events, and mental health problems. We tested whether coping and negative appraisal for stressful events mediated the relations between multiple dimensions of control beliefs and mental health problems. Different dimensions of control beliefs were related to different aspects of coping and negative stress appraisal. Internal control beliefs for positive events were related to both active and avoidant coping. Unknown control beliefs for positive events were related to higher active coping and higher negative appraisal. Unknown control beliefs for negative events were related to higher avoidant coping. In addition, evidence for mediation was found such that the effect of unknown control beliefs for positive events on mental health problems was mediated by negative appraisal. Implications and directions for further research are discussed.

Life-threatening event reduces subjective well-being through activating avoidance motivation: a longitudinal study.

Van Dijk, Dina; Seger-Guttmann, Tali; Heller, Daniel

2013-04-01

Drawing on the approach-avoidance theory, we have examined the role of avoidance motivation in explaining the negative effects of a life-threatening event on subjective well-being (SWB). Residents of the south of Israel were surveyed during heavy missile attacks in January 2009 (T1; n = 283), and again after 6 months (T2; n = 212) and 1 year (T3; n = 154). During the missile attacks, we also surveyed a group from the center of the country (T1; n = 102), not exposed to the attacks. The results indicate that avoidance motivation was activated by the life threat and further mediated its detrimental influence on SWB measures (positive/negative affects, anxiety, and subjective health). Moreover, within the southern sample, the drop in avoidance motivation over time mediated the parallel drop in SWB. In contrast to avoidance motivation, approach motivation remained stable over time and was related to positive emotions. The role of avoidance and approach motivations in life-threatening situations is further discussed. PsycINFO Database Record (c) 2013 APA, all rights reserved.

[Comparative analysis of metabotropic and ionotropic glutamate striatal receptors blockade influence on rats locomotor behaviour].

2013-02-01

The influence of NMDA and metabotropic neostriatal glutamate receptors blockade to avoidance conditioning (in shuttle box) and free locomotor behavior (in open field) in chronic experiments in rats were investigated. The glutamate receptor antagonists were injected bilateral into striatum separately and with the GABA-A receptor antagonist picrotoxin (2 microg), that produced in rats the impairment of avoidance conditioning and choreo-myoklonic hyperkinesis. The most effective in preventing of negative picrotoxin influence on behavior was 5-type metabotropic glutamate receptors antagonist MTEP (3 microg). Separately injected MTEP did not influence on avoidance conditioning and free locomotor behavior. Unlike that, 1-type metabotropic glutamate receptors antagonist EMQMCM (3 microg) impaired normal locomotor behavior and did not prevent the picrotoxin effects. The NMDA glutamate receptors MK 801 (disocilpin--1 and 5 microg) impaired the picrotoxin-induced hyperkinesis, but did not to prevent the negative effects on avoidance conditioning; separately injected MK 801 reduced free locomotor activity. Based on location of investigated receptor types in neostriatal neurons membranes, we proposed that the most effective influence on 5-type metabotropic glutamate receptors is associated with their involvement in "indirect" efferent pathway, suffered in hyperkinetic extrapyramidal motor dysfunction--Huntington's chorea in human.

Focusing on the Negative: Cultural Differences in Expressions of Sympathy

2014-01-01

Feeling concern about the suffering of others is considered a basic human response, and yet, we know surprisingly little about the cultural factors that shape how people respond to the suffering of another person. To this end, we conducted four studies that tested the hypothesis that American expressions of sympathy focus on the negative less and positive more than German expressions of sympathy, in part because Americans want to avoid negative states more than Germans do. In Study 1, we demonstrate that American sympathy cards contained less negative and more positive content than German sympathy cards. In Study 2, we show that European Americans want to avoid negative states more than Germans do. In Study 3, we demonstrate that these cultural differences in “avoided negative affect” mediate cultural differences in how comfortable Americans and Germans felt focusing on the negative (vs. positive) when expressing sympathy for the hypothetical death of an acquaintance's father. To examine whether greater avoided negative affect results in lesser focus on the negative and greater focus on the positive when responding to another person's suffering, in Study 4, American and German participants were randomly assigned to one of two conditions: (1) to “push negative images away” (i.e., increasing desire to avoid negative affect), or (2) to “pull negative images closer” to themselves (i.e., decreasing desire to avoid negative affect). Participants were then asked to pick a card to send to an acquaintance whose father had hypothetically just died. Across cultures, participants in the “push negative away” condition were less likely to choose sympathy cards with negative (vs. positive) content than were those in the “pull negative closer” condition. Together, these studies suggest that cultures differ in their desire to avoid negative affect, and that these differences influence the degree to which expressions of sympathy focus on the negative (vs. positive). We discuss the implications of these findings for current models of sympathy, compassion, and helping. PMID:25243416

Eating-related disinhibition (i.e., a tendency to overeat in response to various stimuli) is associated with weight gain and poorer long-term weight loss success. Theoretically, experiential avoidance (i.e., the desire or attempts to avoid uncomfortable internal experiences), may predispose individuals to developing negative reinforcement eating expectancies (i.e., the belief that eating will help to mitigate distress), which in turn promote disinhibition. Such relationships are consistent with an acquired preparedness model, which posits that dispositions influence learning and subsequent behavior. Drawing from this framework, the current study represents the first investigation of relations between negative reinforcement eating expectancies, experiential avoidance (both general and food-specific) and disinhibited eating. In particular, the mediating role of negative reinforcement eating expectancies in the relation between experiential avoidance and disinhibited eating was examined. Participants (N=107) were overweight and obese individuals presenting for behavioral weight loss treatment who completed measures of general and food-related experiential avoidance, negative reinforcement eating expectancies, and disinhibition. Experiential avoidance and negative reinforcement eating expectancies significantly related to disinhibition. Furthermore, the relation between experiential avoidance and disinhibition was mediated by negative reinforcement eating expectancies. The current study supports an acquired preparedness model for disinhibition, such that the relation between experiential avoidance and disinhibition is accounted for by expectations that eating will alleviate distress. Findings highlight the potential role of eating expectancies in models accounting for obesity risk, and identify negative reinforcement eating expectancies as a potential treatment target for reducing disinhibition.

Lee, Lewina O.; Knight, Bob G.

2009-01-01

Socioemotional selectivity theory suggests that emotion regulation goals motivate older adults to preferentially allocate attention to positive stimuli and away from negative stimuli. This study examined whether anxiety moderates the effect of the positivity bias on attention for threat. We employed the dot probe task to compare subliminal and supraliminal attention for threat in 103 young and 44 older adults. Regardless of anxiety, older but not younger adults demonstrated a vigilant-avoidant response to angry faces. Anxiety influenced older adults’ attention such that anxious individuals demonstrated a vigilant-avoidant reaction to sad faces, but an avoidant-vigilant reaction to negative words. PMID:19739931

Objective: Generalized anxiety disorder is one of the most common anxiety disorders in the general ‎population. Several studies suggest that anxiety sensitivity is a vulnerability factor in generalized ‎anxiety severity. However, some other studies suggest that negative repetitive thinking and ‎experiential avoidance as response factors can explain this relationship. Therefore, this study ‎aimed to investigate the mediating role of experiential avoidance and negative repetitive thinking ‎in the relationship between anxiety sensitivity and generalized anxiety severity.‎ Method: This was a cross-sectional and correlational study. A sample of 475 university students was ‎selected through stratified sampling method. The participants completed Anxiety Sensitivity ‎Inventory-3, Acceptance and Action Questionnaire-II, Perseverative Thinking Questionnaire, and ‎Generalized Anxiety Disorder 7-item Scale. Data were analyzed by Pearson correlation, multiple ‎regression analysis and path analysis.‎ Results: The results revealed a positive relationship between anxiety sensitivity, particularly cognitive ‎anxiety sensitivity, experiential avoidance, repetitive thinking and generalized anxiety severity. In ‎addition, findings showed that repetitive thinking, but not experiential avoidance, fully mediated ‎the relationship between cognitive anxiety sensitivity and generalized anxiety severity. α Level ‎was p<0.005.‎ Conclusion: Consistent with the trans-diagnostic hypothesis, anxiety sensitivity predicts generalized anxiety‏ ‏severity, but its effect is due to the generating repetitive negative thought.‎ PMID:27928245

Avoidant personality disorder is characterized by pervasive anxiety, fear of criticism, disapproval, and rejection, particularly in anticipation of exposure to social situations. An important but underexplored question concerns whether anxiety in avoidant patients is associated with an impaired ability to engage emotion regulatory strategies in anticipation of and during appraisal of negative social stimuli. We examined the use of an adaptive emotion regulation strategy, cognitive reappraisal, in avoidant patients. In addition to assessing individual differences in state and trait anxiety levels, self-reported affect as well as measures of neural activity were compared between 17 avoidant patients and 21 healthy control participants both in anticipation of and during performance of a reappraisal task. Avoidant patients showed greater state and trait-related anxiety relative to healthy participants. In addition, relative to healthy participants, avoidant patients showed pronounced amygdala hyper-reactivity during reappraisal anticipation, and this hyper-reactivity effect was positively associated with increasing self-reported anxiety levels. Our finding of exaggerated amygdala activity during reappraisal anticipation could reflect anxiety about the impending need to reappraise, anxiety about the certainty of an upcoming negative image, or anxiety relating to anticipated scrutiny of task responses by the experimenters. While we believe that all of these possibilities are consistent with the phenomenology of avoidant personality disorder, future research may clarify this ambiguity. These results suggest that amygdala reactivity in anticipation of receiving negative social information may represent a key component of the neural mechanisms underlying the heightened anxiety present in avoidant patients.

Smoking-specific experiential avoidance cognition: explanatory relevance to pre- and post-cessation nicotine withdrawal, craving, and negative affect.

PubMed

Farris, Samantha G; Zvolensky, Michael J; Schmidt, Norman B

2015-05-01

Negative-reinforcement based cognitive processes have been implicated in the maintenance of cigarette smoking. Given the expectation that smoking will attenuate aversive internal experiences, smokers may be particularly unwilling to experience or remain in contact with smoking-related distress (i.e., experiential avoidance). Yet, there is little known about a cognitive-based process termed smoking-specific experiential avoidance with regard to withdrawal, craving, or negative affect during a quit attempt. Data were collected from adult daily smokers (n = 259) participating in a larger smoking cessation trial. Pre- and post-quit experiences of nicotine withdrawal, craving, and negative affect were examined in terms of cognitive-based smoking-specific experimental avoidance, measured by the Avoidance and Inflexibility Scale (AIS). Results indicated that baseline smoking-specific experiential avoidance was associated with greater overall levels of withdrawal, craving, and negative affect at treatment initiation (pre-cessation). Reductions in smoking-specific experiential avoidance from baseline to quit day were associated with increased likelihood of quit day abstinence. Such reductions were also predictive of lower levels of nicotine withdrawal, craving, and negative affect on quit day. Also, less reduction in experiential avoidance was associated with experiencing greater withdrawal in the early phase of quitting. The impact of cognitive-based experiential avoidance pertaining to smoking impacts both pre- and post-cessation experiences in terms of negative affect, withdrawal, and smoking cravings and may represent an important treatment target.

Age-Related Effects on Memory for Social Stimuli: The Role of Valence, Arousal, and Emotional Responses

Hess, Thomas M.; Popham, Lauren E.; Growney, Claire M.

2017-01-01

Background Previous research (Hess, Popham, Dennis, & Emery, 2013) suggested that age-based positivity effects in memory were attenuated with social stimuli. We examined the degree to which this generalized across arousal levels associated with social images. We also examined variations in approach and avoidance responses to images, and how these were differentially related to memory in younger versus older adults. Methods In Experiment 1, young (22 – 43 years) and older (65 – 85 years) adults recalled positive and negative social scenes that were high or low in arousal. In Experiment 2, young (20 – 40 years) and older (65 – 83 years) adults viewed and recalled the same scenes under instructions designed to alter arousal, and approach and avoidance ratings for each image were recorded. Results In Experiment 1, age differences in recall were confined to high-arousal, negative images, with young adults exhibiting superior memory relative to older adults. There was no evidence of an age-related positivity effect for low arousal social scenes. This result was replicated in Experiment 2, but distancing instructions minimized the age difference in recall for high-arousal, negative images. Approach and avoidance ratings differentially predicted recall across age groups, with stronger associations in the young. Conclusion The results are consistent with emerging evidence demonstrating that valence-based biases associated with aging (e.g., positivity effect) are specific to the context and stimulus characteristics. Differences in prediction of recall responses from approach and avoidance ratings across age groups suggested that the observed effects in memory reflected differences in responses to the characteristics of stimuli.

Although graphic health warning labels (GHWs) on cigarette packs have influenced cessation behaviors in other countries, no U.S. studies have explored the impact of avoidance of GHW content among individuals from low socioeconomic position (SEP). The purpose of this study was to determine the predictors of intention to avoid GHWs, and how avoidance impacts cessation intention, in a low SEP sample in the U.S. Data come from low SEP smokers (n = 541) involved in a field experiment. The participants responded to questions pre- and post viewing of GHWs assessing SEP, intention to avoid them, emotional reactions, and intention to seek health information or quit smoking. Backwards stepwise logistic regression determined the predictors for intention to avoid GHWs. Simple and adjusted logistic regression analyzed the association between avoidance and its main predictors and outcomes of intentions to seek information or quit smoking. Predictors for avoidance included being somewhat addicted to cigarettes (OR 2.3, p = 0.002), younger than 25 (OR 2.6, p = 0.008), and having medium (OR 3.4, p < 0.001) or high (OR 4.7, p < 0.001) levels of negative emotional reaction to the labels. Intention to avoid GHWs was positively associated with the intent to look for health information about smoking (OR 2.2, p = 0.002). Higher levels of negative emotional reaction were positively associated with cessation behaviors, with high negative emotional reaction associated with nine times the odds of quitting (p < 0.001). Results indicate avoidance of GHWs does not detract from the labels' benefit and that GHWs are an effective means of communicating smoking risk information among low SEP groups.

The allocation of valenced concepts onto 3D space.

The valence-space metaphor research area investigates the metaphorical mapping of valenced concepts onto space. Research findings from this area indicate that positive, neutral, and negative concepts are associated with upward, midward, and downward locations, respectively, in the vertical plane. The same research area has also indicated that such concepts seem to have no preferential location on the horizontal plane. The approach-avoidance effect consists in decreasing the distance between positive stimuli and the body (i.e. approach) and increasing the distance between negative stimuli and the body (i.e. avoid). Thus, the valence-space metaphor accounts for the mapping of valenced concepts onto the vertical and horizontal planes, and the approach-avoidance effect accounts for the mapping of valenced concepts onto the "depth" plane. By using a cube conceived for the study of allocation of valenced concepts onto 3D space, we show in three studies that positive concepts are placed in upward locations and near the participants' body, negative concepts are placed in downward locations and far from the participants' body, and neutral concepts are placed in between these concepts in both planes.

Treatment of avoidance behavior as an adjunct to exposure therapy: Insights from modern learning theory.

PubMed

Treanor, Michael; Barry, Tom J

Pathological avoidance of benign stimuli is a hallmark of anxiety and related disorders, and exposure-based treatments have often encouraged the removal of avoidance, or safety behaviors, due to their negative effects on extinction learning. Unfortunately, empirical evidence suggests that avoidance behaviors can persist following treatment, and the mere availability of avoidance behavior can be sufficient to renew fear following successful extinction learning. The present paper critically examines the function of avoidance behavior through the lens of modern learning theory, and speculates on novel behavioral and pharmacological strategies for targeting avoidance as an adjunct to current evidence-based treatments.

When reaching goals, organisms must simultaneously meet the overarching goal of conserving energy. According to the law of least effort, organisms will select the means associated with the least effort. The mechanisms underlying this bias remain unknown. One hypothesis is that organisms come to avoid situations associated with unnecessary effort by generating a negative valence toward the stimuli associated with such situations. Accordingly, merely using a dysfunctional, 'slow' computer mouse causes participants to dislike ambient neutral images (Study 1). In Study 2, nonsense shapes were liked less when associated with effortful processing (135° of mental rotation) versus easier processing (45° of rotation). Complementing 'fluency' effects found in perceptuo-semantic research, valence emerged from action-related processing in a principled fashion. The findings imply that negative valence associations may underlie avoidance motivations, and have practical implications for educational/workplace contexts in which effort and positive affect are conducive to success.

Pavlovian conditioning paradigms have revealed fear learning tendencies that may be implicated in the etiology and maintenance of anxiety disorders. Given the prominence of disgust in certain anxiety disorders, it may be fruitful to study disgust learning in addition to fear learning. The present study utilized eye tracking to examine the effects of disgust conditioning on attentional bias, a phenomenon that characterizes anxiety disorders. Participants completed either a disgust condition, in which a face (conditioned stimulus; CS+) was paired with videos of individuals vomiting (unconditioned stimulus; US), or a negative condition in which a face was paired with videos of individuals being harmed in motor-vehicle accidents. Eye movements were used to measure attentional biases related to the USs and the CSs. In line with prior research, attentional avoidance was observed for the disgust CS+. However, this effect did not reach significance until after extinction and was linked to self-reported disgust postacquisition, yet decoupled from self-reported disgust postextinction. Attentional avoidance of the CS+ was not found in the negative condition, and postextinction differences in attentional bias for the CS+ between conditions were found to be mediated by differences in attentional bias for the US, as only the disgust US elicited attentional avoidance. Also, individual differences in disgust sensitivity were found to be associated with attentional avoidance of the disgust US, and this effect was mediated by self-reported disgust in response to the US. Further, disgust sensitivity was associated with attentional avoidance of the disgust CS+, and this effect was mediated by attentional avoidance of the disgust US. These findings provide new insight into a complex pattern of relations between disgust, evaluative learning, and attention that may have implications for the etiology and maintenance of certain anxiety disorders.

Understanding verbal descriptions of everyday actions could involve the neural representation of action direction (avoidance and approach) toward persons and things. We recorded the electrophysiological activity of participants while they were reading approach/avoidance action sentences that were directed toward a target: a thing/a person (i.e., "Petra accepted/rejected Ramón in her group"/ "Petra accepted/rejected the receipt of the bank"). We measured brain potentials time locked to the target word. In the case of things, we found a N400-like component with right frontal distribution modulated by approach/avoidance action. This component was more negative in avoidance than in approach sentences. In the case of persons, a later negative event-related potential (545-750 ms) with left frontal distribution was sensitive to verb direction, showing more negative amplitude for approach than avoidance actions. In addition, more negativity in approach-person sentences was associated with fear avoidance trait, whereas less negativity in avoidance-person sentences was associated with a greater approach trait. Our results support that verbal descriptions of approach/avoidance actions are encoded differently depending on whether the target is a thing or a person. Implications of these results for a social, emotional and motivational understanding of action language are discussed.

Is it beneficial to use Internet-communication for escaping from boredom? Boredom proneness interacts with cue-induced craving and avoidance expectancies in explaining symptoms of Internet-communication disorder

The use of online-communication applications including messengers (e.g. WhatsApp) or social networking services (e.g. Facebook) on the smartphone has turned into daily practice for billions of people, for example during waiting times. An increasing number of individuals show diminished control over their usage of these applications despite negative consequences in everyday life. This can be referred to as Internet-communication disorder (ICD). The current study investigated the effect of boredom proneness on symptoms of an ICD. It further examined the mediating role of cognitive and affective mechanisms, namely expectancies to avoid negative feelings online and cue-induced craving. The results of a structural equation model (N = 148) illustrate that boredom proneness is a risk factor for the development and maintenance of an ICD as it had a significant direct effect on ICD symptoms. Furthermore, boredom proneness predicted avoidance expectancies as well as cue-induced craving. Both in turn enhanced the risk of developing ICD tendencies. Moreover, both variables mediated the effect of boredom proneness on ICD and interacted among each other. In summary, the results demonstrate that people who have a higher susceptibility to experience boredom show higher expectancies to avoid negative emotions online, which promotes higher craving reactions when being confronted with specific cues (e.g. an incoming message), and could result in ICD tendencies.

Within Your Control? When Problem Solving May Be Most Helpful.

Sarfan, Laurel D; Gooch, Peter; Clerkin, Elise M

Emotion regulation strategies have been conceptualized as adaptive or maladaptive, but recent evidence suggests emotion regulation outcomes may be context-dependent. The present study tested whether the adaptiveness of a putatively adaptive emotion regulation strategy-problem solving-varied across contexts of high and low controllability. The present study also tested rumination, suggested to be one of the most putatively maladaptive strategies, which was expected to be associated with negative outcomes regardless of context. Participants completed an in vivo speech task, in which they were randomly assigned to a controllable ( n = 65) or an uncontrollable ( n = 63) condition. Using moderation analyses, we tested whether controllability interacted with emotion regulation use to predict negative affect, avoidance, and perception of performance. Partially consistent with hypotheses, problem solving was associated with certain positive outcomes (i.e., reduced behavioral avoidance) in the controllable (vs. uncontrollable) condition. Consistent with predictions, rumination was associated with negative outcomes (i.e., desired avoidance, negative affect, negative perception of performance) in both conditions. Overall, findings partially support contextual models of emotion regulation, insofar as the data suggest that the effects of problem solving may be more adaptive in controllable contexts for certain outcomes, whereas rumination may be maladaptive regardless of context.

Time Out from Sex or Romance: Sexually Experienced Adolescents' Decisions to Purposefully Avoid Sexual Activity or Romantic Relationships.

Researchers have given significant attention to abstinence among adolescents, but far less is known about purposeful avoidance of sexual activity (and relationship involvement). Typically, it is assumed that, once adolescents have initiated sexual activity, they will thereafter engage in sexual activity if given the opportunity. However, it is unclear whether that is true as some research indicates that many adolescents engage in sexual activity intermittently. Sexually experienced adolescents may purposefully avoid engaging in sexual activity for a period of time and, if so, this has implications for understanding their sexual decision-making. We used a mixed methods approach to investigate sexually experienced adolescents' decisions to purposefully avoid further sexual activity and/or romantic relationships with a focus on how common these decisions are and factors influencing them. Participants were 411 (56 % female) adolescents (16-21 years old) who completed an on-line survey that assessed reasons for each type of avoidance, religiosity, sexual esteem, sexual distress, sexual coercion, and dysfunctional sexual beliefs. Overall, 27 % of participants had engaged in sexual avoidance and 47 % had engaged in romantic avoidance. Significantly more female than male adolescents reported sexual and romantic avoidance. Adolescents' reasons for sexual avoidance included: lack of sexual pleasure or enjoyment, relationship reasons, negative emotions, values, fear of negative outcomes, negative physical experience, and other priorities. Reasons for romantic avoidance included: effects of previous relationship, not interested in commitment, wrong time, other priorities, negative emotions, no one was good enough, and sexual concerns. Logistical regressions were used to assess associations between age, religiosity, sexual esteem, sexual distress, experience of sexual coercion, and dysfunctional sexual beliefs and having engaged in romantic and/or sexual avoidance. The female adolescents who had avoided sexual activity were more likely to have experienced sexual coercion. The male adolescents who had avoided sexual activity were more religious and likely to have experienced sexual coercion. The male adolescents who had avoided romantic relationships were more sexually distressed and likely to have experienced sexual coercion. No associations were found for romantic avoidance among female adolescents. These results reflect considerable agency in the decision-making of adolescents in intimate contexts. They are discussed in terms of their challenge to current discourses about rampant adolescent sexuality as well as their implications for education and prevention interventions that incorporate personal choice and decision-making into their protocols.

You Can't See the Real Me: Attachment Avoidance, Self-Verification, and Self-Concept Clarity.

Attachment shapes people's experiences in their close relationships and their self-views. Although attachment avoidance and anxiety both undermine relationships, past research has primarily emphasized detrimental effects of anxiety on the self-concept. However, as partners can help people maintain stable self-views, avoidant individuals' negative views of others might place them at risk for self-concept confusion. We hypothesized that avoidance would predict lower self-concept clarity and that less self-verification from partners would mediate this association. Attachment avoidance was associated with lower self-concept clarity (Studies 1-5), an effect that was mediated by low self-verification (Studies 2-3). The association between avoidance and self-verification was mediated by less self-disclosure and less trust in partner feedback (Study 4). Longitudinally, avoidance predicted changes in self-verification, which in turn predicted changes in self-concept clarity (Study 5). Thus, avoidant individuals' reluctance to trust or become too close to others may result in hidden costs to the self-concept.

Effects of worry on physiological and subjective reactivity to emotional stimuli in generalized anxiety disorder and nonanxious control participants.

2010-10-01

The present study examined the effect of worry versus relaxation and neutral thought activity on both physiological and subjective responding to positive and negative emotional stimuli. Thirty-eight participants with generalized anxiety disorder (GAD) and 35 nonanxious control participants were randomly assigned to engage in worry, relaxation, or neutral inductions prior to sequential exposure to each of four emotion-inducing film clips. The clips were designed to elicit fear, sadness, happiness, and calm emotions. Self reported negative and positive affect was assessed following each induction and exposure, and vagal activity was measured throughout. Results indicate that worry (vs. relaxation) led to reduced vagal tone for the GAD group, as well as higher negative affect levels for both groups. Additionally, prior worry resulted in less physiological and subjective responding to the fearful film clip, and reduced negative affect in response to the sad clip. This suggests that worry may facilitate avoidance of processing negative emotions by way of preventing a negative emotional contrast. Implications for the role of worry in emotion avoidance are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved).

Background Emerging data suggest that dysphoria is one facet of depression that is especially related to various aspects of cigarette smoking. However, it is presently unknown what emotional processes may account for these relations. Objectives In the current cross-sectional study, the impact of avoidance and inflexibility to smoking (AIS), a smoking-specific form of experiential avoidance, was tested on the relationship of dysphoria to four specific smoking processes that are key factors in cessation: perceived barriers to cessation, severity of problems during prior quit attempts, negative reinforcement smoking expectancies, and motivation to quit smoking. Methods Participants (n = 465) were treatment-seeking adult daily smokers. Relative indirect effects were subjected to bootstrap analyses to test direct and indirect effects of dysphoria on smoking processes. Results After controlling for gender, nicotine dependence severity, drinking problems, cannabis use, negative affectivity, tobacco-related medical problems, and AIS, dysphoria remained directly, positively related to perceived barriers and cessation problems. Additionally, dysphoria was indirectly, positively related to perceived barriers, cessation problems, negative reinforcement smoking expectancies, and motivation to quit indirectly through higher levels of AIS. Conclusion In the context of dysphoria, AIS may explain a wide range of clinically-relevant smoking processes. PMID:25396705

Free-Operant Avoidance Behavior by Rats after Reinforcer Revaluation Using Opioid Agonists and d-Amphetamine

2014-01-01

The associative processes that support free-operant instrumental avoidance behavior are still unknown. We used a revaluation procedure to determine whether the performance of an avoidance response is sensitive to the current value of the aversive, negative reinforcer. Rats were trained on an unsignaled, free-operant lever press avoidance paradigm in which each response avoided or escaped shock and produced a 5 s feedback stimulus. The revaluation procedure consisted of noncontingent presentations of the shock in the absence of the lever either paired or unpaired with systemic morphine and in a different cohort with systemic d-amphetamine. Rats were then tested drug free during an extinction test. In both the d-amphetamine and morphine groups, pairing of the drug and shock decreased subsequent avoidance responding during the extinction test, suggesting that avoidance behavior was sensitive to the current incentive value of the aversive negative reinforcer. Experiment 2 used central infusions of D-Ala2, NMe-Phe4, Gly-ol5]-enkephalin (DAMGO), a mu-opioid receptor agonist, in the periacqueductal gray and nucleus accumbens shell to revalue the shock. Infusions of DAMGO in both regions replicated the effects seen with systemic morphine. These results are the first to demonstrate the impact of revaluation of an aversive reinforcer on avoidance behavior using pharmacological agents, thereby providing potential therapeutic targets for the treatment of avoidance behavior symptomatic of anxiety disorders.

A growing theoretical and research literature suggests that trait and state social anxiety can predict attentional patterns in the presence of emotional stimuli. The current study adds to this literature by examining the effects of state anxiety on visual attention and testing the vigilance-avoidance hypothesis, using a method of continuous visual attentional assessment. Participants were 91 undergraduate college students with high or low trait fear of negative evaluation (FNE), a core aspect of social anxiety, who were randomly assigned to either a high or low state anxiety condition. Participants engaged in a free view task in which pairs of emotional facial stimuli were presented and eye movements were continuously monitored. Overall, participants with high FNE avoided angry stimuli and participants with high state anxiety attended to positive stimuli. Participants with high state anxiety and high FNE were avoidant of angry faces, whereas participants with low state and low FNE exhibited a bias toward angry faces. The study provided partial support for the vigilance-avoidance hypothesis. The findings add to the mixed results in the literature that suggest that both positive and negative emotional stimuli may be important in understanding the complex attention patterns associated with social anxiety. Clinical implications and suggestions for future research are discussed.

Objective Extreme emotional reactivity is a defining feature of borderline personality disorder, yet the neural-behavioral mechanisms underlying this affective instability are poorly understood. One possible contributor would be diminished ability to engage the mechanism of emotional habituation. We tested this hypothesis by examining behavioral and neural correlates of habituation in borderline patients, healthy controls, and a psychopathological control group of avoidant personality disorder patients. Method During fMRI scan acquisition, borderline patients, healthy controls and avoidant personality disorder patients viewed novel and repeated pictures, providing valence ratings at each presentation. Statistical parametric maps of the contrasts of activation during repeat versus novel negative picture viewing were compared between groups. Psychophysiological interaction analysis was employed to examine functional connectivity differences between groups. Results Unlike healthy controls, neither borderline nor avoidant personality disorder participants showed increased activity in dorsal anterior cingulate cortex when viewing repeat versus novel pictures. This failure to increase dorsal anterior cingulate activity was associated with greater affective instability in borderline participants. In addition, borderline and avoidant participants showed smaller insula-amygdala connectivity increases than healthy participants and did not show habituation in ratings of the emotional intensity of the images as did healthy participants. Borderline patients differed from avoidant patients in insula-ventral anterior cingulate connectivity during habituation. Conclusions Borderline patients fail to habituate to negative pictures as do healthy participants and differ from both healthy controls and avoidant patients in neural activity during habituation. A failure to effectively engage emotional habituation processes may contribute to affective instability in borderline patients. PMID:24275960

Safety behaviour plays an important role in the maintenance of social anxiety disorder (SAD). SAD patients engage in various safety behaviours in social situations in order to decrease the risk of negative evaluations from others. The present study examined the effect of safety behaviour on the maintenance of anxiety and negative belief in SAD by using Structural Equation Modelling (SEM). Participants were a healthy group (442) and a SAD group (46) who met the SAD criteria for DSM-IV and who had high scores of SAD symptoms. In the assumed maintenance model, independence variables were safety and avoidance behaviour and dependence variables were anxiety and negative belief. This result showed that the SAD group significantly has more high scores than the healthy group in all scales of anxiety, negative belief and avoidance behaviour, expect for safety behaviour. The result of the multiple-group procedure indicated that safety behaviour contributes more strongly to anxiety and negative belief in the SAD group than in the healthy group. It is speculated that the SAD group have a stronger link between safety behaviour and negative belief than the healthy group, whereas frequency of the use of safety behaviour is equivalent between two groups. These results support the findings of previous studies.

Can older adults resist the positivity effect in neural responding? The impact of verbal framing on event-related brain potentials elicited by emotional images.

2013-10-01

Older adults have demonstrated an avoidance of negative information, presumably with a goal of greater emotional satisfaction. Understanding whether avoidance of negative information is a voluntary, motivated choice or an involuntary, automatic response will be important to differentiate, as decision making often involves emotional factors. With the use of an emotional framing event-related potential (ERP) paradigm, the present study investigated whether older adults could alter neural responses to negative stimuli through verbal reframing of evaluative response options. The late positive potential (LPP) response of 50 older adults and 50 younger adults was recorded while participants categorized emotional images in one of two framing conditions: positive ("more or less positive") or negative ("more or less negative"). It was hypothesized that older adults would be able to overcome a presumed tendency to down-regulate neural responding to negative stimuli in the negative framing condition, thus leading to larger LPP wave amplitudes to negative images. A similar effect was predicted for younger adults, but for positively valenced images, such that LPP responses would be increased in the positive framing condition compared with the negative framing condition. Overall, younger adults' LPP wave amplitudes were modulated by framing condition, including a reduction in the negativity bias in the positive frame. Older adults' neural responses were not significantly modulated, even though task-related behavior supported the notion that older adults were able to successfully adopt the negative framing condition.

The purpose of the current study was to examine the joint influences of experiential avoidance and social problem solving on the link between childhood emotional abuse (CEA) and intimate partner violence (IPV). Experiential avoidance following CEA may interfere with a person's ability to effectively problem solve in social situations, increasing risk for conflict and interpersonal violence. As part of a larger study, 232 women recruited from the community completed measures assessing childhood emotional, physical, and sexual abuse, experiential avoidance, maladaptive social problem solving, and IPV perpetration and victimization. Final trimmed models indicated that CEA was indirectly associated with IPV victimization and perpetration via experiential avoidance and Negative Problem Orientation (NPO) and Impulsivity/Carelessness Style (ICS) social problem solving strategies. Though CEA was related to an Avoidance Style (AS) social problem solving strategy, this strategy was not significantly associated with IPV victimization or perpetration. Experiential avoidance had both a direct and indirect effect, via NPO and ICS social problem solving, on IPV victimization and perpetration. Findings suggest that CEA may lead some women to avoid unwanted internal experiences, which may adversely impact their ability to effectively problem solve in social situations and increase IPV risk.

Experiential avoidance as a moderator of the relationship between anxiety sensitivity and perceived stress.

Bardeen, Joseph R; Fergus, Thomas A; Orcutt, Holly K

2013-09-01

Given the significant deleterious effects of stress on psychological and physical well-being, the present two-part study sought to clarify relations among putative vulnerability factors (i.e., anxiety sensitivity, experiential avoidance) for perceived stress. Relations among anxiety sensitivity, experiential avoidance, and perceived stress were examined using a large college student sample (N=400) in Study 1 and were replicated using a large community sample (N=838) in Study 2. As predicted, experiential avoidance moderated the relationship between anxiety sensitivity and perceived stress. Contrary to expectations, simple effects in both studies revealed that anxiety sensitivity shared a significant positive association with perceived stress at low, but not high, levels of experiential avoidance. The moderating role of experiential avoidance was found to be robust to the effects of general distress. Moreover, anxiety sensitivity and experiential avoidance evidenced a differential pattern of relations with perceived stress than was evidenced with related negative affective states (i.e., anxiety and depression). The present results suggest that experiential avoidance appears to be a vulnerability factor of particular importance for understanding the phenomenology of perceived stress. Conceptual and clinical implications are discussed. Copyright © 2013. Published by Elsevier Ltd.

Reward Devaluation: Dot-Probe Meta-Analytic Evidence of Avoidance of Positive Information in Depressed Persons

Winer, E. Samuel; Salem, Taban

2015-01-01

Cognitive theories of depression and anxiety have traditionally emphasized the role of attentional biases in the processing of negative information. The dot-probe task has been widely used to study this phenomenon. Recent findings suggest that biased processing of positive information might also be an important aspect of developing psychopathological symptoms. However, despite some evidence suggesting persons with symptoms of depression and anxiety may avoid positive information, many dot-probe studies have produced null findings. The present review used conventional and novel meta-analytic methods to evaluate dot-probe attentional biases away from positive information and, for comparison, toward negative information, in depressed and anxious individuals. Results indicated that avoidance of positive information is a real effect exhibiting substantial evidential value among persons experiencing psychopathology, with individuals evidencing primary symptoms of depression clearly demonstrating this effect. Different theoretical explanations for these findings are evaluated, including those positing threat-processing structures, even-handedness, self-regulation, and reward devaluation, with the novel theory of reward devaluation emphasized and expanded. These novel findings and theory suggest that avoidance of prospective reward helps to explain the cause and sustainability of depressed states. Suggestions for future research and methodological advances are discussed. PMID:26619211

The authors examined avoidance personal goals as concurrent (Study 1) and longitudinal (Study 2) predictors of multiple aspects of well-being in the United States and Japan. In both studies, participants adopted more avoidance personal goals in Japan relative to the United States. Both studies also demonstrated that avoidance personal goals were significant negative predictors of the most relevant aspects of well-being in each culture. Specifically, avoidance personal goals were negative predictors of intrapersonal and eudaimonic well-being in the United States and were negative predictors of interpersonal and eudaimonic well-being in Japan. The findings clarify and extend puzzling findings from prior empirical work in this area, and raise provocative possibilities about the nature of avoidance goal pursuit.

Dysfunctional beliefs towards motherhood and postpartum depressive and anxiety symptoms: Uncovering the role of experiential avoidance.

Fonseca, Ana; Monteiro, Fabiana; Canavarro, Maria Cristina

2018-06-06

This study aimed to examine the relationship between dysfunctional motherhood-related beliefs and postpartum anxiety and depression symptoms, and whether experiential avoidance may be a potential mechanism in explaining these relationships. A sample of 262 postpartum women participated in a cross-sectional online survey. The model presented a good fit (CFI = 0.96, RMSEA = 0.077) suggesting that more dysfunctional motherhood-related beliefs related with maternal responsibility and with others' judgments were associated with higher postpartum anxiety and depressive symptoms. Indirect effects through experiential avoidance were also found. Dysfunctional motherhood-related beliefs are cognitive vulnerabilities for postpartum psychological disorders and should be assessed to identify women that may be prone to early interventions. Moreover, dysfunctional beliefs seem to affect psychopathological symptoms by activating experiential avoidance strategies (e.g., rumination), which may accentuate the frequency of women's negative thoughts and emotions. Early interventions should target the promotion of acceptance of private negative experiences (psychological flexibility). © 2018 Wiley Periodicals, Inc.

Academic Self-Handicapping and Achievement Goals: A Further Examination.

2001-01-01

This study extends previous research on the relations among students' personal achievement goals, perceptions of the classroom goal structure, and reports of the use of self-handicapping strategies. Surveys, specific to the math domain, were given to 484 7th-grade students in nine middle schools. Personal performance-avoid goals positively predicted handicapping, whereas personal performance-approach goals did not. Personal task goals negatively predicted handicapping. Perceptions of a performance goal structure positively predicted handicapping, and perceptions of a task goal structure negatively predicted handicapping, independent of personal goals. Median splits used to examine multiple goal profiles revealed that students high in performance-avoid goals used handicapping more than did those low in performance-avoid goals regardless of the level of task goals. Students low in performance-avoid goals and high in task goals handicapped less than those low in both goals. Level of performance-approach goals had little effect on the relation between task goals and handicapping. Copyright 2001 Academic Press.

With the use of an emotional framing event-related potential (ERP) paradigm, the present study investigated whether older adults could alter neural responses to negative stimuli through verbal reframing of evaluative response options. The late-positive potential (LPP) response of 50 older adults and 50 younger adults was recorded while participants categorized emotional images in one of two framing conditions: positive (“more or less positive”) or negative (“more or less negative”). It was hypothesized that older adults would be able to overcome a presumed tendency to down-regulate neural responding to negative stimuli in the negative framing condition thus leading to larger LPP wave amplitudes to negative images. A similar effect was predicted for younger adults but for positively valenced images such that LPP responses would be increased in the positive framing condition compared to the negative framing condition. Overall, younger adults' LPP wave amplitudes were modulated by framing condition, including a reduction in the negativity bias in the positive frame. Older adults' neural responses were not significantly modulated even though task-related behavior supported the notion that older adults were able to successfully adopt the negative framing condition.

Little information exists regarding whether psychosocial variables in irritable bowel syndrome (IBS) vary by geographic location. Adult attachment is an important psychological concept rooted in childhood relationship experience that has not been previously studied in IBS. Catastrophizing and negative pain beliefs have been described in IBS and may be affected by attachment. In this cross-cultural study, we determined: (i) whether attachment differs between IBS patients and controls, (ii) whether geographic location has a significant effect on attachment style, catastrophizing and negative pain beliefs, and (iii) how all three variables correlate with IBS symptom severity. 463 IBS patients, with moderate to severe symptom scores, and 192 healthy controls completed validated questionnaires about attachment, catastrophizing, negative pain beliefs and IBS-SSS in nine locations, USA (New York, Los Angeles), Mexico, Italy (Rome, Bari), Romania, Iran, India, and China. Attachment anxiety and avoidance scores were significantly higher in IBS patients than in controls (p < 0.001). This was particularly true for the fearful-avoidant attachment category, especially in China and Romania. Path analysis showed that attachment anxiety and avoidance had indirect effects on IBS-SSS through catastrophizing (p < 0.0001) and negative pain beliefs (p = 0.005). All three psychosocial measures varied significantly depending on location. In the IBS population studied, attachment style was significantly different in IBS compared to a control population. Geographic differences in attachment, catastrophizing and negative pain beliefs were documented and their correlation with symptom severity and thus, research of psychosocial variables in IBS should take into account the location of the population studied. © 2015 John Wiley & Sons Ltd.

Effects of roads on habitat quality for bears in the southern Appalachians: A long-term study

Reynolds-Hogland, M. J.; Mitchell, M.S.

We tested the hypothesis that gravel roads, not paved roads, had the largest negative effect on habitat quality for a population of American black bears (Ursus americanus) that lived in a protected area, where vehicle collision was a relatively minimal source of mortality. We also evaluated whether road use by bears differed by sex or age and whether annual variation in hard mast productivity affected the way bears used areas near roads. In addition, we tested previous findings regarding the spatial extent to which roads affected bear behavior negatively. Using summer and fall home ranges for 118 black bears living in the Pisgah Bear Sanctuary in western North Carolina during 1981-2001, we estimated both home-range-scale (2nd-order) and within-home-range-scale (3rd-order) selection for areas within 250, 500, 800, and 1,600 m of paved and gravel roads. All bears avoided areas near gravel roads more than they avoided areas near paved roads during summer and fall for 2nd-order selection and during summer for 3rd-order selection. During fall, only adult females avoided areas near gravel roads more than they avoided areas near paved roads for 3rd-order selection. We found a positive relationship between use of roads by adults and annual variability in hard mast productivity. Overall, bears avoided areas within 800 m of gravel roads. Future research should determine whether avoidance of gravel roads by bears affects bear survival. ?? 2007 American Society of Mammalogists.

Filipino Americans and racism: A multiple mediation model of coping.

PubMed

Alvarez, Alvin N; Juang, Linda P

2010-04-01

Although the literature on Asian Americans and racism has been emerging, few studies have examined how coping influences one's encounters with racism. To advance the literature, the present study focused on the psychological impact of Filipino Americans' experiences with racism and the role of coping as a mediator using a community-based sample of adults (N = 199). Two multiple mediation models were used to examine the mediating effects of active, avoidance, support-seeking, and forbearance coping on the relationship between perceived racism and psychological distress and self-esteem, respectively. Separate analyses were also conducted for men and women given differences in coping utilization. For men, a bootstrap procedure indicated that active, support-seeking, and avoidance coping were mediators of the relationship between perceived racism and psychological distress. Active coping was negatively associated with psychological distress, whereas both support seeking and avoidance were positively associated with psychological distress. A second bootstrap procedure for men indicated that active and avoidance coping mediated the relationship between perceived racism and self-esteem such that active coping was positively associated with self-esteem, and avoidance was negatively associated with self-esteem. For women, only avoidance coping had a significant mediating effect that was associated with elevations in psychological distress and decreases in self-esteem. The results highlight the importance of examining the efficacy of specific coping responses to racism and the need to differentiate between the experiences of men and women.

Perhaps unlike other social roles that people may hold, caring for children offers opportunities for both immense joy and incredible frustration. Yet what predicts how parents will feel during caregiving experiences? In the current study, we examined parents' (N = 152) positive emotion, negative emotion, and felt meaning during caregiving using the Day Reconstruction Method. In addition, we tested attachment anxiety and avoidance as predictors of parents' emotion during caregiving relative to their other daily experiences. We found that attachment avoidance was associated with elevated negative emotion and reduced positive emotion and meaning in life across the entire day, whereas attachment anxiety was associated with elevated negative emotion and marginally greater meaning in life, but not positive emotion, across the entire day. Furthermore, caregiving was associated with greater positive emotion and meaning, but not negative emotion, compared to parents' other daily activities. Finally, attachment avoidance, but not anxiety, was associated with lower levels of positive emotion, negative emotion, and felt meaning during caregiving compared to other daily activities. These findings are consistent with other evidence that attachment avoidance is associated with deactivation of emotion in close relationships and suggest that attachment avoidance minimizes the joys of parenting.

Method Effects on an Adaptation of the Rosenberg Self-Esteem Scale in Greek and the Role of Personality Traits.

Michaelides, Michalis P; Koutsogiorgi, Chrystalla; Panayiotou, Georgia

2016-01-01

Rosenberg's Self-Esteem Scale is a balanced, 10-item scale designed to be unidimensional; however, research has repeatedly shown that its factorial structure is contaminated by method effects due to item wording. Beyond the substantive self-esteem factor, 2 additional factors linked to the positive and negative wording of items have been theoretically specified and empirically supported. Initial evidence has revealed systematic relations of the 2 method factors with variables expressing approach and avoidance motivation. This study assessed the fit of competing confirmatory factor analytic models for the Rosenberg Self-Esteem Scale using data from 2 samples of adult participants in Cyprus. Models that accounted for both positive and negative wording effects via 2 latent method factors had better fit compared to alternative models. Measures of experiential avoidance, social anxiety, and private self-consciousness were associated with the method factors in structural equation models. The findings highlight the need to specify models with wording effects for a more accurate representation of the scale's structure and support the hypothesis of method factors as response styles, which are associated with individual characteristics related to avoidance motivation, behavioral inhibition, and anxiety.

Although the emotional outcome of a choice generally affects subsequent decisions, humans can inhibit the influence of emotion. Heart rate variability (HRV) has emerged as an objective measure of individual differences in the capacity for inhibitory control. In the present study, we investigated how individual differences in HRV at rest are associated with the emotional effects of the outcome of a choice on subsequent decision making using a decision-making task in which emotional pictures appeared as decision outcomes. We used a reinforcement learning model to characterize the observed behaviors according to several parameters, namely, the learning rate and the motivational value of positive and negative pictures. Consequently, we found that individuals with a lower resting HRV exhibited a greater negative motivational value in response to negative pictures, suggesting that these individuals tend to avoid negative pictures compared with individuals with a higher resting HRV.

2017-08-29

With its high prevalence and debilitating impact on students, math anxiety is well studied within the educational context. However, the problem has yet to be examined from the psychological perspective, which is necessary in order to produce a more comprehensive perspective and to pave the way for therapeutic intervention. The current study, therefore, was conducted to identify cognitive and behavioral factors relevant to the occurrence and maintenance of math anxiety. Data were collected from 300 grade 9 students (150 females and 150 males) from public and private schools in Bangkok, Thailand. Participants responded to the measures of math anxiety, negative math beliefs, negative math appraisals and math avoidance. Structural equation modeling was conducted. Model fit indices obtained consistently suggested the good fitness of the model to the data [e.g. χ2/df = 0.42, root mean square error of approximation (RMSEA) = 0.00]. Negative math beliefs, negative math appraisals and math avoidance had a significant direct effect on math anxiety. Additionally, the indirect effect of negative math appraisal was observed between negative math beliefs and math anxiety. In summary, the proposed model accounted for 84.5% of the variance in the anxiety. The findings are discussed with particular focus on implications for therapeutic intervention for math anxiety.

Rethinking the role of worry in generalized anxiety disorder: evidence supporting a model of emotional contrast avoidance.

PubMed

Llera, Sandra J; Newman, Michelle G

2014-05-01

The Contrast Avoidance model (Newman & Llera, 2011) proposes that individuals with generalized anxiety disorder (GAD) are hypersensitive to sharp upward shifts in negative emotion that typically accompany negative events, and use worry to maintain sustained intrapersonal negativity in an attempt to avoid these shifts. Although research shows that worry increases negative emotionality and mutes further emotional reactivity to a stressor when compared to the worry period (e.g., Llera & Newman, 2010), no study has tracked changes in negative emotionality from baseline to worry inductions followed by a range of emotional exposures. Further, no study has yet assessed participants' subjective appraisals of prior worry on helping to cope with such exposures. The present study tested the main tenets of the Contrast Avoidance model by randomly assigning participants with GAD (n=48) and nonanxious controls (n=47) to experience worry, relaxation, and neutral inductions prior to sequential exposure to fearful, sad, and humorous film clips. Both physiological (nonspecific skin conductance responses [NS-SCRs]) and self-reported emotional changes were observed. Results indicated that worry boosted negative emotionality from baseline, which was sustained across negative exposures, whereas low negative emotionality during relaxation and neutral inductions allowed for sharp increases in response to exposures. Furthermore, GAD participants found worry to be more helpful than other conditions in coping with exposures, whereas control participants reported the opposite pattern. Results provide preliminary support for the Contrast Avoidance model. This suggests that treatment should focus on underlying avoidance patterns before attempting to reduce worry behavior.

Does the Organized Sexual Murderer Better Delay and Avoid Detection?

PubMed

Beauregard, Eric; Martineau, Melissa

2016-01-01

According to the organized-disorganized model, organized sexual murderers adopt specific behaviors during the commission of their crimes that contribute to avoiding police detection. The current study examines the effect of sexual murderers' organized behaviors on their ability to both delay and/or avoid police detection. Using a combination of negative binomial and logistic regression analyses on a sample of 350 sexual murder cases, findings showed that although both measures of delaying and avoiding detection are positively correlated, different behavioral patterns were observed. For instance, offenders who moved the victim's body were more likely to avoid detection but the victim's body was likely to be recovered faster. Moreover, victim characteristics have an impact on both measures; however, this effect disappears for the measure of delaying detection once the organized behaviors are introduced. Implications of the findings are discussed. © The Author(s) 2014.

[Stress and attitudes toward negative emotions in adolescence].

Ozawa, Eiji

2010-12-01

This study investigated the relationship between stress and attitudes toward negative emotions in adolescents. Adolescent students (N=1500) completed a questionnaire that measured attitudes toward negative emotions, emotional-stress reactions, and stress coping. Analysis of date yielded, two factors of the attitudes toward negative emotions: "Negative feelings about negative emotions" and "Capabilities of switching of negative emotions". In order to examine the theoretical relationships among attitudes toward negative emotions, emotional-stress reactions, and stress coping, a hypothetical model was tested by covariance structure analysis. This model predicted that students who have a high level of attitudes toward negative emotions would report enhanced problem solving which promoted stress coping. The results indicated that "Negative feelings about negative emotions" enhanced avoidable coping, and avoidable coping enhanced stress reactions. "Capabilities of switching of negative emotions" was related to a decrease of avoidable coping. Based on the results from covariance structure analysis and a multiple population analysis, the clinical significance and developmental characteristics were discussed.

"Yummy" versus "Yucky"! Explicit and implicit approach-avoidance motivations towards appealing and disgusting foods.

Wanting and rejecting food are natural reactions that we humans all experience, often unconsciously, on a daily basis. However, in the food domain, the focus to date has primarily been on the approach tendency, and researchers have tended not to study the two opposing tendencies in a balanced manner. Here, we develop a methodology with which to understand people's implicit and explicit reactions to both positive (appealing) and negative (disgusting) foods. It consists of a combination of direct and indirect computer-based tasks, as well as a validated food image stimulus set, specifically designed to investigate motivational approach and avoidance responses towards foods. Fifty non-dieting participants varying in terms of their hunger state (hungry vs. not hungry) reported their explicit evaluations of pleasantness, wanting, and disgust towards the idea of tasting each of the food images that were shown. Their motivational tendencies towards those food items were assessed indirectly using a joystick-based approach-avoidance procedure. For each of the food images that were presented, the participants had to move the joystick either towards or away from themselves (approach and avoidance movements, respectively) according to some unrelated instructions, while their reaction times were recorded. Our findings demonstrated the hypothesised approach-avoidance compatibility effect: a significant interaction of food valence and direction of movement. Furthermore, differences between the experimental groups were observed. The participants in the no-hunger group performed avoidance (vs. approach) movements significantly faster; and their approach movements towards positive (vs. negative) foods were significantly faster. As expected, the self-report measures revealed a strong effect of the food category on the three dependent variables and a strong main effect of the hunger state on wanting and to a lesser extent on pleasantness.

Background Diabetes is one of the most common noncommunicable diseases around the world that accompanies assorted psychiatric disorders including anxiety and depression due to being chronic. Objective The aim of this study was to evaluate the effect of anxiety and depression on acceptance and action, considering emotional schemas of diabetics referring to diabetes clinics of health centers in Birjand, Iran. Methods This study was conducted in 2016 and was a correlational study with a structural equation modeling approach. The statistical population of this study were all men and women with type 2 diabetes in Birjand, with an active health record in health centers of this county. To collect data, Depression, Anxiety, and Stress Scale (DASS-21), Acceptance and Action Questionnaire-II (AAQ-II) and Leahy Emotional Schema Scale (LESS) were employed. Using SPSS19 and LISREL, data were analyzed via multiple regression and modeling at p≤0.05. Results In general, 350 subjects entered the study, most of whom were between 50 and 60 years of age and of whom, (47.7%) were women. Results show that depression has had a negative contribution in predicting quality of life (p=0.0001). In addition, results demonstrated the negative relation of anxiety and depression in predicting no emotional avoidance (flexibility) (p=0.0001). Anxiety and rumination had a positive effect and emotional unawareness had a negative effect on predicting no emotional avoidance (p=0.0001). Conclusion Results of this study showed that by reducing adaptive emotional schemas, emotions reduce psychological flexibility and increase emotional avoidance. In addition, by increasing non-adaptive emotional schemas, it increases no flexibility and emotional avoidance that finally reduces quality of life as well as acceptance and action. PMID:29238497

Context Negative symptoms are a core feature of schizophrenia, but their pathophysiology remains unclear. Objective Negative symptoms are defined by the absence of normal function. However, there must be a productive mechanism that leads to this absence. Here, we test a reinforcement learning account suggesting that negative symptoms result from a failure to represent the expected value of rewards coupled with preserved loss avoidance learning. Design Subjects performed a probabilistic reinforcement learning paradigm involving stimulus pairs in which choices resulted in either reward or avoidance of loss. Following training, subjects indicated their valuation of the stimuli in a transfer task. Computational modeling was used to distinguish between alternative accounts of the data. Setting A tertiary care research outpatient clinic. Patients A total of 47 clinically stable patients with a diagnosis of schizophrenia or schizoaffective disorder and 28 healthy volunteers participated. Patients were divided into high and low negative symptom groups. Main Outcome measures 1) The number of choices leading to reward or loss avoidance and 2) performance in the transfer phase. Quantitative fits from three different models were examined. Results High negative symptom patients demonstrated impaired learning from rewards but intact loss avoidance learning, and failed to distinguish rewarding stimuli from loss-avoiding stimuli in the transfer phase. Model fits revealed that high negative symptom patients were better characterized by an “actor-critic” model, learning stimulus-response associations, whereas controls and low negative symptom patients incorporated expected value of their actions (“Q-learning”) into the selection process. Conclusions Negative symptoms are associated with a specific reinforcement learning abnormality: High negative symptoms patients do not represent the expected value of rewards when making decisions but learn to avoid punishments through the use of prediction errors. This computational framework offers the potential to understand negative symptoms at a mechanistic level. PMID:22310503

Regional inactivations of primate ventral prefrontal cortex reveal two distinct mechanisms underlying negative bias in decision making.

PubMed

Clarke, Hannah F; Horst, Nicole K; Roberts, Angela C

2015-03-31

Dysregulation of the orbitofrontal and ventrolateral prefrontal cortices is implicated in anxiety and mood disorders, but the specific contributions of each region are unknown, including how they gate the impact of threat on decision making. To address this, the effects of GABAergic inactivation of these regions were studied in marmoset monkeys performing an instrumental approach-avoidance decision-making task that is sensitive to changes in anxiety. Inactivation of either region induced a negative bias away from punishment that could be ameliorated with anxiolytic treatment. However, whereas the effects of ventrolateral prefrontal cortex inactivation on punishment avoidance were seen immediately, those of orbitofrontal cortex inactivation were delayed and their expression was dependent upon an amygdala-anterior hippocampal circuit. We propose that these negative biases result from deficits in attentional control and punishment prediction, respectively, and that they provide the basis for understanding how distinct regional prefrontal dysregulation contributes to the heterogeneity of anxiety disorders with implications for cognitive-behavioral treatment strategies.

Learning processes underlying avoidance of negative outcomes.

Successful avoidance of a threatening event may negatively reinforce the behavior due to activation of brain structures involved in reward processing. Here, we further investigated the learning-related properties of avoidance using feedback-related negativity (FRN). The FRN is modulated by violations of an intended outcome (prediction error, PE), that is, the bigger the difference between intended and actual outcome, the larger the FRN amplitude is. Twenty-eight participants underwent an operant conditioning paradigm, in which a behavior (button press) allowed them to avoid a painful electric shock. During two learning blocks, participants could avoid an electric shock in 80% of the trials by pressing one button (avoidance button), or by not pressing another button (punishment button). After learning, participants underwent two test blocks, which were identical to the learning ones except that no shocks were delivered. Participants pressed the avoidance button more often than the punishment button. Importantly, response frequency increased throughout the learning blocks but it did not decrease during the test blocks, indicating impaired extinction and/or habit formation. In line with a PE account, FRN amplitude to negative feedback after correct responses (i.e., unexpected punishment) was significantly larger than to positive feedback (i.e., expected omission of punishment), and it increased throughout the blocks. Highly anxious individuals showed equal FRN amplitudes to negative and positive feedback, suggesting impaired discrimination. These results confirm the role of negative reinforcement in motivating behavior and learning, and reveal important differences between high and low anxious individuals in the processing of prediction errors. © 2017 Society for Psychophysiological Research.

The authors explored the contribution of individual differences in attachment orientations to the experience of sexual intercourse and its association with relationship quality. In Study 1, 500 participants completed self-report scales of attachment orientations and sexual experience. The findings indicated that whereas attachment anxiety was associated with an ambivalent construal of sexual experience, attachment avoidance was associated with more aversive sexual feelings and cognitions. In Study 2, 41 couples reported on their attachment orientations and provided daily diary measures of sexual experiences and relationship interactions for a period of 42 days. Results showed that attachment anxiety amplified the effects of positive and negative sexual experiences on relationship interactions. In contrast, attachment avoidance inhibited the positive relational effect of having sex and the detrimental relational effects of negative sexual interactions. The authors discuss the possibility that attachment orientations are associated with different sex-related strategies and goals within romantic relationships.

The Talking Cure of Avoidant Personality Disorder: Remission through Earned-Secure Attachment.

PubMed

Guina, Jeffrey

The concept of earned security is important and has significant implications for psychotherapy. Understanding how individuals with insecure attachment styles can develop secure attachment styles through reparative relationships, such as the therapeutic relationship, can assist psychotherapists in helping patients to overcome the effects of early negative life experiences. Personality disorders are commonly associated with negative experiences, such as abuse, neglect, and other empathic failures. These disorders are particularly difficult to treat because of their pervasive nature and the resultant defense mechanisms that often thwart psychotherapy. However, an understanding of the role that attachment can play in the etiology, symptomatology, and treatment of psychopathology can greatly enhance the therapeutic process. This case report describes the long-term psychodynamic psychotherapy of a woman with a history of childhood trauma, avoidant attachment style, and avoidant personality disorder. Through the therapeutic relationship, she developed a secure attachment, and her symptoms remitted, and her life drastically improved.

Actor and Partner Effects of Attachment on Relationship Satisfaction and Sexual Satisfaction Across the Genders: An APIM Approach.

Previous studies found gender differences in relationship satisfaction and sexuality. We tested gender differences in associations between attachment, a lasting relationship determinant, and two outcomes, relationship and sexual satisfaction. This study improves on earlier research by examining these associations in one Actor-Partner-Interdependence-Model, making direct statistical testing between outcomes possible. Furthermore, a community and a distressed sample (N = 113 heterosexual couples each) were included to attempt replication across samples and to examine clinical implications. In both genders, actor attachment avoidance negatively affected relationship satisfaction and (with one exception) sexual satisfaction. Also in both genders, partner attachment avoidance negatively affected sexual satisfaction. However, whereas partner attachment avoidance influenced female relationship satisfaction, it did not affect male relationship satisfaction. The findings replicated across samples. Clinical implications are discussed. © 2017 American Association for Marriage and Family Therapy.

The present study examined the differences of conflict coping tactics in adolescents' grade and gender and parents' gender and explored the relationships among conflict frequency, conflict coping tactics, and life satisfaction. A total of 1874 Chinese students in grades 7, 8, 10, and 11 completed surveys on conflict frequency, coping tactics, and life satisfaction. The results obtained by MANOVA suggested that the adolescents' reported use of assertion and avoidance with either mothers or fathers increased from Grade 7 to Grade 8 and did not change from Grade 8 to Grade 11 in parent-adolescent conflicts. The results of paired sample T-tests indicated that adolescents used more conciliation in Grade 7, more conciliation and assertion in Grade 8, and more conciliation and less avoidance in Grade 10 and 11 to cope with mothers than with fathers in parent-adolescent conflicts. Boys used more conciliation and less avoidance, while girls used more conciliation, assertion and third-party intervention to cope with mothers than with fathers in parent-adolescent conflicts. The results of the hierarchical regression analysis indicated the significance of the primary effects of conflict frequency and coping tactics on life satisfaction. Specifically, conflict frequency negatively predicted life satisfaction. Conciliation positively and avoidance negatively predicted life satisfaction when adolescents coped with either mothers or fathers in parent-adolescent conflicts. Assertion negatively predicted life satisfaction when adolescents coped with fathers. The moderating effects of conflict coping tactics on the relationship between parent-adolescent conflict frequency and life satisfaction were not significant. PMID:26528224

Reward devaluation: Dot-probe meta-analytic evidence of avoidance of positive information in depressed persons.

PubMed

Winer, E Samuel; Salem, Taban

2016-01-01

Cognitive theories of depression and anxiety have traditionally emphasized the role of attentional biases in the processing of negative information. The dot-probe task has been widely used to study this phenomenon. Recent findings suggest that biased processing of positive information might also be an important aspect of developing psychopathological symptoms. However, despite some evidence suggesting persons with symptoms of depression and anxiety may avoid positive information, many dot-probe studies have produced null findings. The present review used conventional and novel meta-analytic methods to evaluate dot-probe attentional biases away from positive information and, for comparison, toward negative information, in depressed and anxious individuals. Results indicated that avoidance of positive information is a real effect exhibiting substantial evidential value among persons experiencing psychopathology, with individuals evidencing primary symptoms of depression clearly demonstrating this effect. Different theoretical explanations for these findings are evaluated, including those positing threat-processing structures, even-handedness, self-regulation, and reward devaluation, with the novel theory of reward devaluation emphasized and expanded. These novel findings and theory suggest that avoidance of prospective reward helps to explain the cause and sustainability of depressed states. Suggestions for future research and methodological advances are discussed. (c) 2015 APA, all rights reserved).

Major depressive disorder is characterized by emotional dysfunction, but mood states in daily life are not well understood. This study examined complex explanatory models of daily stress and coping mechanisms that trigger and maintain daily negative affect and (lower) positive affect in depression. Sixty-three depressed patients completed perfectionism measures, and then completed daily questionnaires of stress appraisals, coping, and affect for 7 consecutive days. Multilevel structural equation modeling (MSEM) demonstrated that, across many stressors, when the typical individual with depression perceives more criticism than usual, he/she uses more avoidant coping and experiences higher event stress than usual, and this is connected to daily increases in negative affect as well as decreases in positive affect. In parallel, results showed that perceived control, less avoidant coping, and problem-focused coping commonly operate together when daily positive affect increases. MSEM also showed that avoidant coping tendencies and ongoing stress, in combination, explain why people with depression and higher self-critical perfectionism maintain daily negative affect and lower positive affect. These findings advance a richer and more detailed understanding of specific stress and coping patterns to target in order to more effectively accomplish the two predominant therapy goals of decreasing patients' distress and strengthening resilience.

Studies that examined the negative impact of violence in emergency departments on nurses' leave and avoidance behavior are well-documented. However, few studies provided an integrated model of how and when violence influences their leave and avoidance behavior. The study adopted Affective Events Theory to propose and examine a model of violent events, negative emotions, and (leave and avoidance) behaviors on nurses in emergency departments and further analyzed whether the model is salient to nurses' occupational burnout, nursing experience, and nursing rank. The sample included 123 emergency department nurses at a teaching hospital in northern, Taiwan. All participants had experienced violent incidents within the preceding 6 months. Moderated mediation analysis suggested that nurses experienced one of two emotional processes following violent incidents: "violence-negative feelings toward work-intention to resign" or "violence-negative emotion and physical symptoms-avoidance tendencies." Moreover, nurses with high burnout levels expressed weaker intention to resign after violent incidents, while nurses with more experience and higher rank were less likely to avoid violence after violent incidents. Emergency nurses do not simply elect to escape but may engage in avoidance behavior. This study revealed that how violent incidents affect nurses' resignation or avoidance behaviors depends on how they feel. Occupational burnout and nurses' attributes affected their behavior.

Punishment and the potential for negative reinforcement with histamine injection.

Mayer, Paulo César Morales; de Carvalho Neto, Marcus Bentes; Katz, Jonathan L

The present study examined punishment of responding with histamine injection, and its potential to generate avoidance of punishment. Sprague-Dawley rats were trained under concurrent schedules in which responses on one lever (the punishment lever) produced food under a variable-interval schedule, and under some conditions intermittent injections of histamine, which suppressed behavior. Responses on a second (avoidance) lever prevented histamine injections scheduled on the punishment lever. After stabilization of punished responding, a variable-interval 15-s schedule of cancellation of histamine (avoidance) was added for responding on the second/avoidance lever, without subsequent acquisition of responding on that lever. Progressive decreases in the length of the punishment variable-interval schedule increased suppression on the punishment lever without increases in response rates on the avoidance lever. Exchanging contingencies on the levers ensured that response rates on the avoidance lever were sufficiently high to decrease the histamine injection frequency; nonetheless response rates on the avoidance lever decreased over subsequent sessions. Under no condition was responding maintained on the avoidance lever despite continued punishing effectiveness of histamine throughout. The present results suggest that avoidance conditioning is not a necessary condition for effective punishment, and confirm the importance of empirical rather than presumed categorization of behavioral effects of stimulus events.

Age differences in emotion regulation effort: Pupil response distinguishes reappraisal and distraction for older but not younger adults.

In previous research, older adults show greater emotional benefits from distracting themselves than from reappraising an event when strategically regulating emotion. Older adults also demonstrate an attentional preference to avoid, while younger adults show a bias toward approaching negative stimuli. This suggests a possible age-related differentiation of cognitive effort across approach and avoidance of negative stimuli during emotion regulation. In this study, we tracked cognitive effort via pupil dilation during the use of distraction (avoidance) and reappraisal (approach) strategies across age. Forty-eight younger adults (M = 20.94, SD = 1.78; 19 men) and 48 older adults (M = 68.82, SD = 5.40; 15 men) viewed a slideshow of negative images and were instructed to distract, reappraise, or passively view each image. Older adults showed greater pupil dilation during reappraisal than distraction, but younger adults displayed no difference between conditions-an effect that survived when controlling for gaze patterns. Gaze findings revealed that older adults looked less within images during active emotion regulation compared with passive viewing (no difference between distraction and reappraisal), and younger adults showed no difference across strategies. Younger adults gazed less within the most emotional image areas during distraction, but this did not significantly contribute to pupil response. Our findings support that distraction is less cognitively effortful than reinterpreting negative information in later life. These findings could be explained by older adults' motivational bias to disengage from negative information because of the age-related positivity effect, or compensation for decreased working memory resources across the life span.

Reactivity to negative affect in smokers: the role of implicit associations and distress tolerance in smoking cessation.

PubMed

Cameron, Amy; Reed, Kathleen Palm; Ninnemann, Andrew

2013-12-01

Avoidance of negative affect is one motivational factor that explains smoking cessation relapse during cessation attempts. This negative reinforcement model of smoking cessation and relapse has demonstrated the importance of one's ability to tolerate nicotine withdrawal symptoms, particularly negative affect states, in remaining abstinent from smoking. Distress tolerance and implicit associations are two individual constructs that may influence the strength of this relationship. In this pilot study the authors examined implicit associations related to avoidance and negative affect using a modified Implicit Association Test (IAT), a measure designed to examine implicit associations related to negative affect and avoidance, and the relationship of these associations to distress tolerance and smoking relapse. In total, 40 participants were recruited through community flyers as part of a larger smoking cessation study. Participants completed a brief smoking history, behavioral distress tolerance assessments, and the modified IAT. Smoking status was assessed via phone 3days and 6days post-quit date. Results from a Cox proportional hazard model revealed that implicit associations between avoidance and negative affect were significantly negatively correlated with time to relapse after a smoking cessation attempt, whereas the behavioral distress tolerance assessments did not predict time to relapse. This study provides novel information about the cognitive associations that may underlie avoidant behavior in smokers, and may be important for understanding smoking relapse when negative affect states are particularly difficult to tolerate. Authors discuss the importance of implicit associations in understanding smoking relapse and how they can be targeted in treatment. © 2013.

Impulsivity and temporal frame: Reducing frequency of snacking by highlighting immediate health benefits.

PubMed

Pavey, Louisa; Churchill, Sue

2017-08-01

The current study aimed to examine the effect of giving temporally framed health information regarding either the immediate or long-term health consequences of consuming high-calorie snacks, for people with high Negative Urgency (a dimension of impulsivity), and for those primed with impulsivity. We expected that for participants with high Negative Urgency, and those primed with impulsivity, information which detailed the immediate health benefits of avoiding snack consumption would be more effective than information which detailed long-term health benefits. Participants (N=110) completed a measure of Negative Urgency, reported their snacking frequency over the previous seven days, and completed either an impulsivity or neutral prime task. Following this, they read information detailing either the immediate or long-term health benefits of avoiding high-calorie snacks. High-calorie snack consumption was reported 7days later. The results showed a significant three-way interaction between Negative Urgency, prime task, and temporal frame. Participants who were primed with impulsivity and those high in Negative Urgency showed a greater reduction in snacking frequency after being given information about the immediate vs. long-term health benefits of snacking. The results suggest that the immediacy of health consequences should be considered when designing health information to reduce impulsive snacking behaviour. Copyright © 2017.

The relevance of goal-orientation for motivation in high versus low proneness to negative symptoms.

Schlier, Björn; Engel, Maike; Fladung, Anne-Katharina; Fritzsche, Anja; Lincoln, Tania M

2017-06-01

The psychological mechanisms of why individuals with negative symptoms fail to initiate and perform goal-directed behavior are not well understood. Drawing on the reward-sensitivity and expectancy-value theories, we investigate whether negative symptom-like experiences (NSLE) are associated with generating less approach goals (aimed at reaching a positive outcome) and more avoidance goals (aimed at avoiding a negative outcome) and whether this type of goal-orientation explains motivational deficits (i.e., perceiving goals as less feasible and important and being less committed to them). Based on the continuum model of negative symptoms, we identified two parallelized extreme groups with high and low levels of NSLE (n = 37, respectively) in an ad-hoc online-sample of healthy individuals (N = 262) using the Community Assessment of Psychic Experiences. In an online study, these participants were instructed to generate approach and avoidance goals and to rate each goal in terms of feasibility, importance and goal-commitment. Participants with low levels of NSLE generated more approach than avoidance goals. Participants with high levels of NSLE showed no such difference due to increased numbers of avoidance goals. Furthermore, avoidance goal-orientation predicted reduced subjective feasibility and importance of goals and less goal-commitment. Results are based on a healthy sample rather than people with psychosis. No longitudinal or behavioral data for goal-striving was collected. People with NSLE generate more avoidance goals than controls. This is dysfunctional because it correlates with feeling less committed to reach one's goals. Optimizing goal-setting could be a promising starting-point for psychological interventions aimed at reducing negative symptoms. Copyright © 2017 Elsevier Ltd. All rights reserved.

Child Gain Approach and Loss Avoidance Behavior: Relationships With Depression Risk, Negative Mood, and Anhedonia.

2015-08-01

Reduced reward responsiveness and altered response to loss of reward are observed in adults with major depressive disorder (MDD) and adolescents at increased risk for MDD based on family history. However, it is unclear whether altered behavioral responsiveness to reward/loss is a lifelong marker of MDD risk, which is evident before the normative adolescent increase in incentive responding. Healthy 7- to 10-year-old children of mothers with MDD (high risk: n = 27) or without MDD (low risk: n = 42) performed 2 signal detection tasks assessing response bias toward reward (approach) and away from loss (avoidance). Differences in approach/avoidance were related to MDD risk, child general depressive symptoms (maternal report), child-reported anhedonic symptoms, and child-reported negative mood symptoms via repeated-measures analysis of variance. MDD risk did not significantly relate to gain approach or loss avoidance. However, within high-risk children, higher numbers of maternal depressive episodes predicted blunted loss avoidance. Blunted gain approach was related to elevated anhedonic symptoms, whereas enhanced loss avoidance was related to elevated negative mood. Elevated negative mood was further related to blunted gain approach in high-risk children but related to enhanced gain approach in low-risk children. In children, individual differences in specific depressive symptoms and recurrence of maternal depression significantly predicted gain approach/loss avoidance, but the presence/absence of maternal MDD did not. Child depressive symptoms characterized by low positive affect (anhedonia) were related to blunted gain responsiveness, whereas elevated depressed/negative mood was related to enhanced loss responsiveness. Findings suggest that relations between gain approach and negative mood may be an important distinction between those at high versus low risk for MDD.

When avoiding unpleasant emotions might not be such a bad thing: verbal-autonomic response dissociation and midlife conjugal bereavement.

PubMed

Bonanno, G A; Keltner, D; Holen, A; Horowitz, M J

1995-11-01

It has been widely assumed that emotional avoidance during bereavement leads to either prolonged grief, delayed grief, or delayed somatic symptoms. To test this view, as well as a contrasting adaptive hypothesis, emotional avoidance was measured 6 months after a conjugal loss as negative verbal-autonomic response dissociation (low self-rated negative emotion coupled with heightened cardiovascular activity) and compared with grief measured at 6 and 14 months. The negative dissociation score evidenced reliability and validity but did not evidence the assumed link to severe grief. Rather, consistent with the adaptive hypothesis, negative dissociation at 6 months was associated with minimal grief symptoms across 14 months. Negative dissociation scores were also linked to initially high levels of somatic symptoms, which dropped to a low level by 14 months. Possible explanations for the initial cost and long-term adaptive quality of emotional avoidance during bereavement, as well as implications and limitations of the findings, are discussed.

A meta-analysis of 25 years of mood-creativity research: hedonic tone, activation, or regulatory focus?

PubMed

Baas, Matthijs; De Dreu, Carsten K W; Nijstad, Bernard A

2008-11-01

This meta-analysis synthesized 102 effect sizes reflecting the relation between specific moods and creativity. Effect sizes overall revealed that positive moods produce more creativity than mood-neutral controls (r= .15), but no significant differences between negative moods and mood-neutral controls (r= -.03) or between positive and negative moods (r= .04) were observed. Creativity is enhanced most by positive mood states that are activating and associated with an approach motivation and promotion focus (e.g., happiness), rather than those that are deactivating and associated with an avoidance motivation and prevention focus (e.g., relaxed). Negative, deactivating moods with an approach motivation and a promotion focus (e.g., sadness) were not associated with creativity, but negative, activating moods with an avoidance motivation and a prevention focus (fear, anxiety) were associated with lower creativity, especially when assessed as cognitive flexibility. With a few exceptions, these results generalized across experimental and correlational designs, populations (students vs. general adult population), and facet of creativity (e.g., fluency, flexibility, originality, eureka/insight). The authors discuss theoretical implications and highlight avenues for future research on specific moods, creativity, and their relationships.

Neuroticism as Distancing: Perceptual Sources of Evidence

PubMed Central

Liu, Tianwei; Ode, Scott; Moeller, Sara K.; Robinson, Michael D.

2013-01-01

Several theories and self-reported sources of data link individual differences in negative affectivity to avoidance motivation. Chronic avoidance motivation, through repeated practice, may result in a relatively cognitive distance-enhancing dynamic whereby events and stimuli are perceived as further away from the self, even when they are not threatening. Such predictions are novel, but follow from cybernetic theories of self-regulation. In five studies (total N = 463), relations of this type were investigated. Study 1 presented participants with phrases that were ambiguous and found that trait negative affect predicted phrase interpretation in a distance-enhancing temporal direction. Study 2 replicated this effect across a systematic manipulation of event valence. Study 3 asked individuals to estimate the size of words and found that individuals higher in neuroticism generally perceived words to be smaller than did individuals lower in neuroticism. In Study 4, people high (but not low) in neuroticism perceived words to be shrinking faster than they were growing. In Study 5, greater perceptual distancing, in a font size estimation task, predicted more adverse reactions to negative events in daily life. Although normative effects varied across studies, consistent support for a chronic distancing perspective of individual differences in negative affectivity was found. PMID:23527850

Combat PTSD and Implicit Behavioral Tendencies for Positive Affective Stimuli: A Brief Report

Background: Prior cognitive research in posttraumatic stress disorder (PTSD) has focused on automatic responses to negative affective stimuli, including attentional facilitation or disengagement and avoidance action tendencies. More recent research suggests PTSD may also relate to differences in reward processing, which has lead to theories of PTSD relating to approach-avoidance imbalances. The current pilot study assessed how combat-PTSD symptoms relate to automatic behavioral tendencies to both positive and negative affective stimuli. Method: Twenty male combat veterans completed the approach-avoidance task (AAT), Clinician Administered PTSD Scale, Beck Depression Inventory-II, and State-Trait Anger Expression Inventory-II. During the AAT, subjects pulled (approach) or pushed (avoid) a joystick in response to neutral, happy, disgust, and angry faces based on border color. Bias scores were calculated for each emotion type (avoid-approach response latency differences). Main and interaction effects for psychological symptom severity and emotion type on bias score were assessed using linear mixed models. Results: There was a significant interaction between PTSD symptoms and emotion type, driven primarily by worse symptoms relating to a greater bias to avoid happy faces. Post hoc tests revealed that veterans with worse PTSD symptoms were slower to approach as well as quicker to avoid happy faces. Neither depressive nor anger symptoms related to avoid or approach tendencies of emotional stimuli. Conclusion: Posttraumatic stress disorder severity was associated with a bias for avoiding positive affective stimuli. These results provide further evidence that PTSD may relate to aberrant processing of positively valenced, or rewarding stimuli. Implicit responses to rewarding stimuli could be an important factor in PTSD pathology and treatment. Specifically, these findings have implications for recent endeavors in using computer-based interventions to influence automatic approach-avoidance tendencies. PMID:27252673

Many researchers have reported that exposure to war and ongoing political violence increases mental health problems in children. Results of studies have also shown a high prevalence (58-80%) of post-traumatic stress disorder in war-affected children living in the occupied Palestinian territory. The aim of this study was to estimate the direct and indirect effects of perceived life satisfaction on the consequences of children's exposure to trauma and the balance of positive and negative affect. Palestinian children were recruited from primary schools in four refugee camps in the Gaza Strip (Bureij, Gaza Beach Camp, Jabalia, Rafah). All children had been involved in or witnessed one or more episodes of violence involving other people in the 2 months prior to the study (the 2012 Gaza War). We used the Multidimensional Students Life Satisfaction Scale (peers, self, living environment, school, family), the Positive and Negative Affect Scale for Children, and the revised Children Impact of Events scale (intrusion and avoidance symptoms) to test (through structural equation modelling) the moderation effect of life satisfaction on war trauma via positive emotions. 1276 Palestinian children were enrolled in this study. The model tested with structural equation modelling was robust. Children's life satisfaction influenced both the intrusion (β=-0·48; p=0.003) and avoidance (β=-11; p=0·021) effects of primary traumatisation. The consequences of primary traumatisation by intrusion (β=0·34; p=0·008) and avoidance (β=0·27; p=0.011) contributed to increasing negative affect. Finally, perceived life satisfaction had direct effects on affective experience, specifically increasing positive affect and diminishing negative affect. Perceived quality of life in children has a role in controlling war-related traumas. Life satisfaction contributes both directly and indirectly to change affectivity. When children perceive themselves to be highly satisfied with their home and school environment, living conditions, and relationships with peers and parents, the effects of trauma are less severe.

It is well established that emotion and cognition interact in humans, but such an interaction has not been extensively studied in nonhuman primates. We investigated whether emotional value can affect nonhuman primates' processing of stimuli that are only mentally represented, not visually available. In a short-term memory task, baboons memorized the location of two target squares of the same color, which were presented with a distractor of a different color. Through prior long-term conditioning, one of the two colors had acquired a negative valence. Subjects were slower and less accurate on the memory task when the targets were negative than when they were neutral. In contrast, subjects were faster and more accurate when the distractors were negative than when they were neutral. Some of these effects were modulated by individual differences in emotional disposition. Overall, the results reveal a pattern of cognitive avoidance of negative stimuli, and show that emotional value alters cognitive processing in baboons even when the stimuli are not physically present. This suggests that emotional influences on cognition are deeply rooted in evolutionary continuity.

Experiential avoidance as a generalized psychological vulnerability: comparisons with coping and emotion regulation strategies.

2006-09-01

Extending previous work, we conducted two studies concerning the toxic influences of experiential avoidance (EA) as a core mechanism in the development and maintenance of psychological distress, and disruption of pleasant, engaging, and spontaneous activity. Of particular interest was whether EA accounted for relationships between coping and emotion regulation strategies on anxiety-related pathology (Study 1) and psychological distress and hedonic functioning over the course of a 21-day monitoring period (Study 2). In Study 1, EA mediated the effects of maladaptive coping, emotional responses styles, and uncontrollability on anxiety-related distress (e.g., anxiety sensitivity, trait anxiety, suffocation fears, and body sensation fears). In Study 2, EA completely mediated the effects of two emotion regulation strategies (i.e., suppression and reappraisal) on daily negative and positive experiences and was associated with diminished daily positive affective experiences and healthy life appraisals, diminished frequency of positive events and more frequent negative life events, and greater negative affective experiences. The present data show that cognitive reappraisal, a primary process of traditional cognitive-behavior therapy, was much less predictive of the quality of psychological experiences and events in everyday life compared with EA. Further consideration of experiential avoidance as a generalized diathesis and toxic process will be useful in improving our understanding of the etiology, phenomenology, and treatment of anxiety conditions, general human suffering, and disruptions in hedonic capacity.

Phase accumulation tracking algorithm for effective index retrieval of fishnet metamaterials and other resonant guided wave networks

Feigenbaum, Eyal; Hiszpanski, Anna M.

2017-07-01

A phase accumulation tracking (PAT) algorithm is proposed and demonstrated for the retrieval of the effective index of fishnet metamaterials (FMMs) in order to avoid the multi-branch uncertainty problem. This algorithm tracks the phase and amplitude of the dominant propagation mode across the FMM slab. The suggested PAT algorithm applies to resonant guided wave networks having only one mode that carries the light between the two slab ends, where the FMM is one example of this metamaterials sub-class. The effective index is a net effect of positive and negative accumulated phase in the alternating FMM metal and dielectric layers, with a negative effective index occurring when negative phase accumulation dominates.

A Transient Dopamine Signal Represents Avoidance Value and Causally Influences the Demand to Avoid

2018-01-01

Abstract While an extensive literature supports the notion that mesocorticolimbic dopamine plays a role in negative reinforcement, recent evidence suggests that dopamine exclusively encodes the value of positive reinforcement. In the present study, we employed a behavioral economics approach to investigate whether dopamine plays a role in the valuation of negative reinforcement. Using rats as subjects, we first applied fast-scan cyclic voltammetry (FSCV) to determine that dopamine concentration decreases with the number of lever presses required to avoid electrical footshock (i.e., the economic price of avoidance). Analysis of the rate of decay of avoidance demand curves, which depict an inverse relationship between avoidance and increasing price, allows for inference of the worth an animal places on avoidance outcomes. Rapidly decaying demand curves indicate increased price sensitivity, or low worth placed on avoidance outcomes, while slow rates of decay indicate reduced price sensitivity, or greater worth placed on avoidance outcomes. We therefore used optogenetics to assess how inducing dopamine release causally modifies the demand to avoid electrical footshock in an economic setting. Increasing release at an avoidance predictive cue made animals more sensitive to price, consistent with a negative reward prediction error (i.e., the animal perceives they received a worse outcome than expected). Increasing release at avoidance made animals less sensitive to price, consistent with a positive reward prediction error (i.e., the animal perceives they received a better outcome than expected). These data demonstrate that transient dopamine release events represent the value of avoidance outcomes and can predictably modify the demand to avoid. PMID:29766047

Emotional valence and contextual affordances flexibly shape approach-avoidance movements

PubMed Central

Saraiva, Ana Carolina; Schüür, Friederike; Bestmann, Sven

2013-01-01

Behavior is influenced by the emotional content—or valence—of stimuli in our environment. Positive stimuli facilitate approach, whereas negative stimuli facilitate defensive actions such as avoidance (flight) and attack (fight). Facilitation of approach or avoidance movements may also be influenced by whether it is the self that moves relative to a stimulus (self-reference) or the stimulus that moves relative to the self (object-reference), adding flexibility and context-dependence to behavior. Alternatively, facilitation of approach avoidance movements may happen in a pre-defined and muscle-specific way, whereby arm flexion is faster to approach positive (e.g., flexing the arm brings a stimulus closer) and arm extension faster to avoid negative stimuli (e.g., extending the arm moves the stimulus away). While this allows for relatively fast responses, it may compromise the flexibility offered by contextual influences. Here we asked under which conditions approach-avoidance actions are influenced by contextual factors (i.e., reference-frame). We manipulated the reference-frame in which actions occurred by asking participants to move a symbolic manikin (representing the self) toward or away from a positive or negative stimulus, and move a stimulus toward or away from the manikin. We also controlled for the type of movements used to approach or avoid in each reference. We show that the reference-frame influences approach-avoidance actions to emotional stimuli, but additionally we find muscle-specificity for negative stimuli in self-reference contexts. We speculate this muscle-specificity may be a fast and adaptive response to threatening stimuli. Our results confirm that approach-avoidance behavior is flexible and reference-frame dependent, but can be muscle-specific depending on the context and valence of the stimulus. Reference-frame and stimulus-evaluation are key factors in guiding approach-avoidance behavior toward emotional stimuli in our environment. PMID:24379794

This study explored the relationships among psychological abuse, attitudes about intimate partner violence (IPV), negative mood regulation expectancies (NMRE), and coping. Participants were 126 female college students in dating, cohabitating, or married relationships within the previous year. In one single session, they completed self-report scales measuring IPV, NMRE, and coping. Results indicated that women reporting higher levels of psychological abuse reported less negative attitudes toward IPV, engaged in less-active coping responses, and had lower NMRE. Psychological abuse was a significant predictor of avoidant coping, while NMRE significantly predicted both active and avoidant coping. In addition, the interaction of NMRE × Psychological abuse added incremental prediction of avoidant coping. Implications for research and practice are discussed. © The Author(s) 2014.

Sex-specific effect of the anabolic steroid, 17α-methyltestosterone, on inhibitory avoidance learning in periadolescent rats

The illicit use of anabolic androgenic steroids (AAS) has gained popularity among adolescents in the last decade. However, although it is known that exposure to AAS impairs cognition in adult animal models, the cognitive effects during adolescence remain undetermined. An inhibitory avoidance task (IAT) was used to assess the effect of AAS (17α-methyltestosterone; 17α-meT-7.5 mg/kg) in male and female periadolescent rats. A single injection of 17α-meT immediately before the footshock produced significant impairment of inhibitory avoidance learning in males but not females. Generalized anxiety, locomotion, and risk assessment behaviors (RAB) were not affected. Our results show that exposure to a single pharmacological dose of 17α-meT during periadolescence exerts sex-specific cognitive effects without affecting anxiety. Thus, disruption of the hormonal milieu during this early developmental period might have negative impact on learning and memory. PMID:23792034

The psychology of doing nothing: forms of decision avoidance result from reason and emotion.

PubMed

Anderson, Christopher J

2003-01-01

Several independent lines of research bear on the question of why individuals avoid decisions by postponing them, failing to act, or accepting the status quo. This review relates findings across several different disciplines and uncovers 4 decision avoidance effects that offer insight into this common but troubling behavior: choice deferral, status quo bias, omission bias, and inaction inertia. These findings are related by common antecedents and consequences in a rational-emotional model of the factors that predispose humans to do nothing. Prominent components of the model include cost-benefit calculations, anticipated regret, and selection difficulty. Other factors affecting decision avoidance through these key components, such as anticipatory negative emotions, decision strategies, counterfactual thinking, and preference uncertainty, are also discussed.

Inbreeding avoidance through non-random mating in sticklebacks

Frommen, Joachim G; Bakker, Theo C.M

2006-01-01

Negative effects of inbreeding are well documented in a wide range of animal taxa. Hatching success and survival of inbred offspring is reduced in many species and inbred progeny are often less attractive to potential mates. Thus, individuals should avoid mating with close kin. However, experimental evidence for inbreeding avoidance through non-random mating in vertebrates is scarce. Here, we show that gravid female three-spined sticklebacks (Gasterosteus aculeatus) when given the choice between a courting familiar brother and a courting unfamiliar non-sib prefer to mate with the non-sib and thus avoid the disadvantages of incest. We controlled for differences in males' body size and red intensity of nuptial coloration. Thus, females adjust their courting behaviour to the risk of inbreeding. PMID:17148370

The implications of temporal distance on motivation-related concepts were examined. The results of an experiment, based on 585 Grade 6 students, indicated that both positive (approach) and negative (avoidance) motivation increased as the future goal or event approached in time. This increase in approach and avoidance motivation influenced the performance of the pupils differently. For pupils with success orientation, the performance increased. For pupils with failure orientation, the performance remained about the same.

Addiction is characterized by persistence to seek drug reinforcement despite negative consequences. Drug-induced aberrations in approach and avoidance processing likely facilitate the sustenance of addiction pathology. Currently, the effects of repeated drug exposure on the resolution of conflicting approach and avoidance motivational signals have yet to be thoroughly investigated. The present study sought to investigate the effects of cocaine pre-exposure on conflict resolution using novel approach-avoidance paradigms. We used a novel mixed-valence conditioning paradigm to condition cocaine-pre-exposed rats to associate visuo-tactile cues with either the delivery of sucrose reward or shock punishment in the arms in which the cues were presented. Following training, exploration of an arm containing a superimposition of the cues was assessed as a measure of conflict resolution behavior. We also used a mixed-valence runway paradigm wherein cocaine-pre-exposed rats traversed an alleyway toward a goal compartment to receive a pairing of sucrose reward and shock punishment. Latency to enter the goal compartment across trials was taken as a measure of motivational conflict. Our results reveal that cocaine pre-exposure attenuated learning for the aversive cue association in our conditioning paradigm and enhanced preference for mixed-valence stimuli in both paradigms. Repeated cocaine pre-exposure allows appetitive approach motivations to gain greater influence over behavioral output in the context of motivational conflict, due to aberrant positive and negative incentive motivational processing.

How Stereotype Threat Affects Healthy Older Adults’ Performance on Clinical Assessments of Cognitive Decline: The Key Role of Regulatory Fit

Mather, Mara; Gatz, Margaret

2015-01-01

Objectives. Stereotype threat can impair older adults’ performance on clinical assessments for cognitive decline. We examined why this occurs. Based upon the regulatory focus account of stereotype threat, we predicted that the effects of stereotype threat should depend upon the assessments’ reward structure. Stereotype threat should be associated with poor performance when the assessment emphasizes gaining correct answers, but not when it emphasizes avoiding mistakes. Method. Healthy older adults completed a series of mental status examinations. Half of the participants completed these examinations under stereotype threat about their cognitive abilities. Monetary incentives were also manipulated. For half of the participants correct responding led to gains. For the remaining participants incorrect responding/forgetting led to losses. Results. Consistent with the regulatory focus account, stereotype threat was associated with poor performance when the mental status examinations had a gains-based structure, but not when they had a losses-based structure. Discussion. Older adults respond to stereotype threat by becoming vigilant to avoid the losses that will make them their worst. Researchers and clinicians can capitalize on this motivational change to combat stereotype threat’s negative effects. By using a loss-avoidance frame, stereotype threat’s negative effects can be attenuated or even eliminated. PMID:25752896

To assess the relationship between session-by-session mediators and treatment outcomes in traditional cognitive-behavioral therapy (CBT) and acceptance and commitment therapy (ACT) for social anxiety disorder. Session-by-session changes in negative cognitions (a theorized mediator of CBT) and experiential avoidance (a theorized mediator of ACT) were assessed in 50 adult outpatients randomized to CBT (n=25) or ACT (n=25) for DSM-IV social anxiety disorder. Multilevel modeling analyses revealed significant nonlinear decreases in the proposed mediators in both treatments, with ACT showing steeper decline than CBT at the beginning of treatment and CBT showing steeper decline than ACT at the end of treatment. Curvature (or the nonlinear effect) of experiential avoidance during treatment significantly mediated posttreatment social anxiety symptoms and anhedonic depression in ACT, but not in CBT, with steeper decline of the Acceptance and Action Questionnaire at the beginning of treatment predicting fewer symptoms in ACT only. Curvature of negative cognitions during both treatments predicted outcome, with steeper decline of negative cognitions at the beginning of treatment predicting lower posttreatment social anxiety and depressive symptoms. Rate of change in negative cognitions at the beginning of treatment is an important predictor of change across both ACT and CBT, whereas rate of change in experiential avoidance at the beginning of treatment is a mechanism specific to ACT.

2010-04-01

In an IDTV environment, which facilitates self-scheduling, skipping advertisements by zipping is an emerging ad-avoidance behavior. This study explores whether an alternative ad format, called simultaneous presentation advertising (SPA), may overcome the limitations of classical sequential advertising (CSA) in controlling zipping behavior and increasing the effectiveness of ads. The experiment revealed that SPA is more effective than CSA in reducing zipping and increasing recall, but SPA was more intrusive and produced a negative product image. There was no difference regarding cognitive avoidance. This work discusses the implications of these findings in the interactive media environment.

Attachment insecurity, biased perceptions of romantic partners' negative emotions, and hostile relationship behavior.

2015-05-01

In the current research, we tested the extent to which attachment insecurity produces inaccurate and biased perceptions of intimate partners' emotions and whether more negative perceptions of partners' emotions elicit the damaging behavior often associated with attachment insecurity. Perceptions of partners' emotions as well as partners' actual emotions were assessed multiple times in couples' conflict discussions (Study 1) and daily during a 3-week period in 2 independent samples (Study 2). Using partners' reports of their own emotional experiences as the accuracy benchmark, we simultaneously tested whether attachment insecurity was associated with the degree to which individuals (a) accurately detected shifts in their partners' negative emotions (tracking accuracy), and (b) perceived their partners were feeling more negative relationship-related emotions than they actually experienced (directional bias). Highly avoidant perceivers were equally accurate at tracking their partners' changing emotions compared to less avoidant individuals (tracking accuracy), but they overestimated the intensity of their partners' negative emotions to a greater extent than less avoidant individuals (directional bias). In addition, more negative perceptions of partners' emotions triggered more hostile and defensive behavior in highly avoidant perceivers both during conflict discussions (Study 1) and in daily life (Study 2). In contrast, attachment anxiety was not associated with tracking accuracy, directional bias, or hostile reactions to perceptions of their partners' negative emotions. These findings demonstrate the importance of assessing biased perceptions in actual relationship interactions and reveal that biased perceptions play an important role in activating the defenses of avoidantly attached people.

Singularities in loop quantum cosmology.

We show that simple scalar field models can give rise to curvature singularities in the effective Friedmann dynamics of loop quantum cosmology (LQC). We find singular solutions for spatially flat Friedmann-Robertson-Walker cosmologies with a canonical scalar field and a negative exponential potential, or with a phantom scalar field and a positive potential. While LQC avoids big bang or big rip type singularities, we find sudden singularities where the Hubble rate is bounded, but the Ricci curvature scalar diverges. We conclude that the effective equations of LQC are not in themselves sufficient to avoid the occurrence of curvature singularities.

A novel theory of experiential avoidance in generalized anxiety disorder: A review and synthesis of research supporting a contrast avoidance model of worry☆,☆☆

PubMed Central

Newman, Michelle G.; Llera, Sandra J.

2011-01-01

An important emphasis of the literature on generalized anxiety disorder (GAD) has been to achieve a greater understanding of the function of emotion (e.g., avoidance, dysregulation) in the etiology and maintenance of this disorder. The purpose of the following paper is to propose a new way of conceptualizing emotional sequelae in GAD by detailing the Contrast Avoidance Model of Worry. In presenting this model, we review theory and data that led to our current position, which is that individuals with GAD are more sensitive to feeling emotionally vulnerable to unexpected negative events, and that worry (the key pathological feature of GAD) is employed to prolong and maintain a negative emotional state thereby avoiding an unexpected negative emotional shift, or contrast experience. We also discuss implications for treatment given the presence of a new target for emotional exposure techniques. Finally, we establish the Contrast Avoidance Model within the framework of extant theories and models of pathogenic processes of GAD. PMID:21334285

Neuroticism as distancing: perceptual sources of evidence.

PubMed

Liu, Tianwei; Ode, Scott; Moeller, Sara K; Robinson, Michael D

2013-05-01

Several theories and self-reported sources of data link individual differences in negative affectivity to avoidance motivation. Chronic avoidance motivation, through repeated practice, may result in a relatively cognitive distance-enhancing dynamic whereby events and stimuli are perceived as further away from the self, even when they are not threatening. Such predictions are novel but follow from cybernetic theories of self-regulation. In 5 studies (total N = 463), relations of this type were investigated. Study 1 presented participants with phrases that were ambiguous and found that trait negative affect predicted phrase interpretation in a distance-enhancing temporal direction. Study 2 replicated this effect across a systematic manipulation of event valence. Study 3 asked individuals to estimate the size of words and found that individuals higher in neuroticism generally perceived words to be smaller than did individuals lower in neuroticism. In Study 4, people high (but not low) in neuroticism perceived words to be shrinking faster than they were growing. In Study 5, greater perceptual distancing, in a font size estimation task, predicted more adverse reactions to negative events in daily life. Although normative effects varied across studies, consistent support for a chronic distancing perspective of individual differences in negative affectivity was found.

Indecision and avoidant procrastination: the role of morningness-eveningness and time perspective in chronic delay lifestyles.

PubMed

Díaz-Morales, Juan Francisco; Ferrari, Joseph R; Cohen, Joseph R

2008-07-01

The authors examined how time orientation and morningness-eveningness relate to 2 forms of procrastination: indecision and avoidant forms. Participants were 509 adults (M age = 49.78 years, SD = 6.14) who completed measures of time orientation, morningness-eveningness, decisional procrastination (i.e., indecision), and avoidant procrastination. Results showed that morningness was negatively related to avoidant procrastination but not decisional procrastination. Overall, the results indicated different temporal profiles for indecision and avoidant procrastinations. Avoidant procrastination related to low future time orientation and low morningness, whereas indecision related to both (a) high negative and high positive past orientations and (b) low present-hedonistic and low future time orientations. The authors inferred that distinct forms of procrastination seem different on the basis of dimensions of time.

Trauma exposure and smoking co-occur at an alarmingly high rate. However, there is little understanding of the mechanisms underlying this clinically significant relation. The present study examined perceived stress as an explanatory mechanism linking posttraumatic stress symptom severity and smoking-specific avoidance/inflexibility, perceived barriers to smoking cessation, and negative affect reduction/negative reinforcement expectancies from smoking among trauma-exposed smokers. Participants were trauma-exposed, treatment-seeking daily cigarette smokers (n = 179; 48.0% female; Mage = 41.17; SD = 12.55). Results indicated that posttraumatic stress symptom severity had an indirect significant effect on each of the dependent variables via perceived stress. The present results provide empirical support that perceived stress may be an underlying mechanism that indirectly explains posttraumatic symptoms relation to smoking-specific avoidance/inflexibility, perceived barriers to smoking cessation, and negative affect reduction/negative reinforcement expectancies among trauma-exposed smokers. These findings suggest that there may be clinical utility in targeting perceived stress among trauma-exposed smokers via stress management psychoeducation and skills training. PMID:27100473

Depression and anxiety mediate the relationship between temperament and character and psychotic-like experiences in healthy subjects.

In this study we examined the hypothesis that depression and anxiety may mediate the relationship between personality traits and both positive and negative psychotic-like experiences (PLEs) in healthy adults. The Community Assessment of Psychic Experiences (CAPE) scale, Temperament and Character Inventory (TCI), Beck Depression Inventory (BDI) and State and Trait Anxiety Inventory (STAI) were administered to 492 healthy individuals. Multiple stepwise regression and mediation analyses were performed to examine whether depressive and anxiety symptoms influence the relationship between the TCI dimensions and positive and negative PLEs. Self-transcendence, persistence, novelty-seeking and self-directedness significantly predicted positive PLEs; self-directedness and harm avoidance were predictable for negative PLEs. Self-transcendence, self-directedness, persistence and harm avoidance also predicted the distress caused by positive PLEs, whereas self-directedness and harm avoidance predicted distress raised by negative PLEs. Depressive symptoms and the state of anxiety partially mediated the linkage between self-directedness and positive PLEs, and between self-directedness, harm avoidance and negative PLEs. Our findings confirm that the personality pattern influences both positive and negative PLEs as well as distress caused by experiencing positive and negative PLEs, and they indicate that certain personality traits may influence the development of PLEs via the emotional pathway of heightened depression and anxiety.

To explore the relationships between optimism, self-efficacy, symptom distress, treatment complexity, illness appraisal, coping, and mood disturbance in patients with advanced-stage cancer.
. Cross-sectional study.
. Smilow Cancer Hospital at Yale New Haven in Connecticut, an outpatient comprehensive cancer center.
. A convenience sample of 121 adult patients with stages III-IV cancer undergoing active chemotherapy.
. Participants completed common self-report questionnaires to measure variables. Treatment hours and visits were calculated from data retrieved from medical record review. Mediation and path analysis were conducted to identify direct and indirect pathways from the significant antecedent variables to mood disturbance.
. Dispositional optimism, self-efficacy, social support, treatment complexity, symptom distress, illness appraisal, coping, and mood disturbance.
. Greater optimism and self-efficacy were associated with less negative illness appraisal, less avoidant coping, and decreased mood disturbance. Conversely, greater symptom distress was associated with greater negative illness appraisal, greater avoidant coping, and greater mood disturbance. In the final model, optimism and symptom distress had direct and indirect effects on mood disturbance. Indirect effects were partially mediated by illness appraisal.
. Mood disturbance resulted from an interaction of disease stressors, personal resources, and cognitive appraisal of illness. Avoidant coping was associated with greater disturbed mood, but neither avoidant nor active coping had a significant effect on mood in the multivariate model. 
. Illness appraisal, coping style, and symptom distress are important targets for intervention. Optimism is a beneficial trait and should be included, along with coping style, in comprehensive nursing assessments of patients with cancer.

The secure base script (SBS) framework is one method of assessing implicit internal working models of attachment; recently, researchers have applied this method to analyze narratives regarding relationship experiences. This study examines the associations between attachment avoidance and SBS content when parents recall a positive moment of connection between themselves and their children (relational savoring) as well as their association with parental emotion and reflective functioning (RF). Using a sample of parents (N = 155, 92% female) of young children (53% boys, M age = 12.76 months), we found that parental attachment avoidance is inversely associated with SBS content during relational savoring, and that SBS content is an indirect effect explaining the association between attachment avoidance and postsavoring (positive and negative) emotion as well as avoidance and poststressor RF. Findings have implications for understanding attachment and parenting. © 2017 Michigan Association for Infant Mental Health.

Beliefs about Emotions, Depression, Anxiety and Fatigue: A Mediational Analysis.

PubMed

Sydenham, Mia; Beardwood, Jennifer; Rimes, Katharine A

2017-01-01

Beliefs that it is unacceptable to experience or express negative emotions have been found to be associated with various clinical problems. It is unclear how such beliefs, which could be viewed as a form of unhelpful perfectionism about emotions, may contribute to symptomatology. This study investigated two hypotheses: a) greater endorsement of beliefs about the unacceptability of negative emotions will be associated with greater emotional avoidance and lower levels of support-seeking and self-compassion; b) these beliefs about emotions will be associated with higher levels of symptoms of depression, anxiety and fatigue and that this relationship will be mediated by social support-seeking, emotional avoidance and self-compassion. Online questionnaires were completed by 451 community participants. Mediational analyses were undertaken to investigate emotional avoidance, social support-seeking and self-compassion as mediators of the relationship between beliefs about emotions and symptoms of depression, anxiety and fatigue. Beliefs about the unacceptability of negative emotions were significantly associated with more emotional avoidance and less self-compassion and support-seeking. The relationships between beliefs about emotions and depression, anxiety and fatigue were significantly mediated by self-compassion and emotional avoidance but not social support-seeking. Future research should investigate whether interventions that pay particular attention to emotional avoidance and self-compassion, such as mindfulness-based therapy or modified forms of CBT, may be beneficial in reducing distress and fatigue associated with beliefs about the unacceptability of negative emotions.

In light of its role in maintaining psychological equanimity, we proposed that nostalgia--a self-relevant, social, and predominantly positive emotion--regulates avoidance and approach motivation. We advanced a model in which (a) avoidance motivation triggers nostalgia and (b) nostalgia, in turn, increases approach motivation. As a result, nostalgia counteracts the negative impact of avoidance motivation on approach motivation. Five methodologically diverse studies supported this regulatory model. Study 1 used a cross-sectional design and showed that avoidance motivation was positively associated with nostalgia. Nostalgia, in turn, was positively associated with approach motivation. In Study 2, an experimental induction of avoidance motivation increased nostalgia. Nostalgia then predicted increased approach motivation. Studies 3-5 tested the causal effect of nostalgia on approach motivation and behavior. These studies demonstrated that experimental nostalgia inductions strengthened approach motivation (Study 3) and approach behavior as manifested in reduced seating distance (Study 4) and increased helping (Study 5). The findings shed light on nostalgia's role in regulating the human motivation system.

Hemispheric Asymmetries in Striatal Reward Responses Relate to Approach-Avoidance Learning and Encoding of Positive-Negative Prediction Errors in Dopaminergic Midbrain Regions.

Some individuals are better at learning about rewarding situations, whereas others are inclined to avoid punishments (i.e., enhanced approach or avoidance learning, respectively). In reinforcement learning, action values are increased when outcomes are better than predicted (positive prediction errors [PEs]) and decreased for worse than predicted outcomes (negative PEs). Because actions with high and low values are approached and avoided, respectively, individual differences in the neural encoding of PEs may influence the balance between approach-avoidance learning. Recent correlational approaches also indicate that biases in approach-avoidance learning involve hemispheric asymmetries in dopamine function. However, the computational and neural mechanisms underpinning such learning biases remain unknown. Here we assessed hemispheric reward asymmetry in striatal activity in 34 human participants who performed a task involving rewards and punishments. We show that the relative difference in reward response between hemispheres relates to individual biases in approach-avoidance learning. Moreover, using a computational modeling approach, we demonstrate that better encoding of positive (vs negative) PEs in dopaminergic midbrain regions is associated with better approach (vs avoidance) learning, specifically in participants with larger reward responses in the left (vs right) ventral striatum. Thus, individual dispositions or traits may be determined by neural processes acting to constrain learning about specific aspects of the world.

Background Research on reactivity to alcohol and drug cues has either ignored affective state altogether or has focused rather narrowly on the role of negative affect in craving. Moreover, until recently, the relevant analyses of affect and craving have rarely addressed the ambivalence often associated with craving itself. The current study investigated how both negative and positive affect moderate approach and avoidance inclinations associated with cue-elicited craving in a clinical sample diagnosed with substance use disorders. Methods One hundred forty-four patients (age range 18–65, mean 42.0; n = 92 male) were recruited from an inpatient detoxification unit for substance abuse. Participants completed a baseline assessment of both positive and negative affect prior to completing a cue-reactivity paradigm for which they provided self-report ratings of inclinations to approach (use) and avoid (not use) alcohol, cigarettes, and non-psychoactive control substances (food and beverages). Results Participants with elevated negative affect reported significantly higher approach ratings for cigarette and alcohol cues, whereas those high in positive affect showed significantly higher levels of avoidance inclinations for both alcohol and cigarette cues and also significantly lower approach ratings for alcohol cues, all relative to control cues. Conclusions Results for negative affect are consistent with previous cue reactivity research, whereas results for positive affect are unique and call attention to its clinical potential for attenuating approach inclinations to substance use cues. Further, positive affect was related to both approach and avoidance inclinations, underscoring the utility of a multidimensional conceptualization of craving in the analysis. PMID:23380493

Automatic optimism: the affective basis of judgments about the likelihood of future events.

Lench, Heather C

2009-05-01

People generally judge that the future will be consistent with their desires, but the reason for this desirability bias is unclear. This investigation examined whether affective reactions associated with future events are the mechanism through which desires influence likelihood judgments. In 4 studies, affective reactions were manipulated for initially neutral events. Compared with a neutral condition, events associated with positive reactions were judged as likely to occur, and events associated with negative reactions were judged as unlikely to occur. Desirability biases were reduced when participants could misattribute affective reactions to a source other than future events, and the relationship between affective reactions and judgments was influenced when approach and avoidance motivations were independently manipulated. Together, these findings demonstrate that positive and negative affective reactions to potential events cause the desirability bias in likelihood judgments and suggest that this effect occurs because of a tendency to approach positive possibilities and avoid negative possibilities.

Linking Individual Learning Styles to Approach-Avoidance Motivational Traits and Computational Aspects of Reinforcement Learning

2016-01-01

Learning how to gain rewards (approach learning) and avoid punishments (avoidance learning) is fundamental for everyday life. While individual differences in approach and avoidance learning styles have been related to genetics and aging, the contribution of personality factors, such as traits, remains undetermined. Moreover, little is known about the computational mechanisms mediating differences in learning styles. Here, we used a probabilistic selection task with positive and negative feedbacks, in combination with computational modelling, to show that individuals displaying better approach (vs. avoidance) learning scored higher on measures of approach (vs. avoidance) trait motivation, but, paradoxically, also displayed reduced learning speed following positive (vs. negative) outcomes. These data suggest that learning different types of information depend on associated reward values and internal motivational drives, possibly determined by personality traits. PMID:27851807

The Yin and Yang of support from significant others: Influence of general social support and partner support of avoidance in the context of treatment for social anxiety disorder.

Rapee, Ronald M; Peters, Lorna; Carpenter, Leigh; Gaston, Jonathan E

2015-06-01

Support from social networks is generally considered to protect against mental disorder but in some circumstances support for negative behaviours (such as avoidance) may be counterproductive. Given the critical interplay between social anxiety disorder and social interactions, it is surprising that the relationship of support from significant others to this disorder has received so little attention. The current study evaluated the reciprocal relationships between perceived social support and perceived partner support for avoidance behaviours (avoidance support) among a sample of 131 participants with social anxiety disorder who were assessed three times within the context of a treatment outcome study. A new measure of partner support for avoidance behaviours was developed, called the Avoidance Support Measure, and showed adequate internal consistency and construct validity. Correlations at baseline showed significant negative relationships between perceived social support and social anxiety and significant positive relationships between avoidance support and social anxiety. Path analysis showed that perceived social support at Times 1 and 2 negatively predicted future social anxiety at Times 2 and 3. On the other hand, only a single predictive relationship involving avoidance support was significant and showed that social anxiety at Time 1 positively predicted avoidance support at Time 2. These early results point to the different ways that support from significant others might relate to social anxiety and suggest that further work in this area may be fruitful.

Ageism among Israeli students: structure and demographic influences.

PubMed

Bodner, Ehud; Lazar, Aryeh

2008-10-01

Research concerning negative attitudes toward the elderly among samples of North American respondents has uncovered two distinct yet comparable three-factor structures: (1) avoidance, antilocution and separation; and (2) discrimination, stereotypes and affective attitudes. In addition, previous research has demonstrated that men and younger people have more negative attitudes toward the elderly than do women and older people. The aim of this study is to examine the extent to which these findings can be generalized to individuals from a different culture. The Fraboni Scale of Ageism (FSA) was administered to 491 Israeli participants aged 20-50 years. Exploratory factor analysis with varimax rotation uncovered a three-factor structure, similar to previous investigations. In contrast to the literature, however, no simple group (gender, age) differences were found for ageism. However, discriminant function analysis revealed a more complex relationship between age, gender and ageism. Older males, in contrast to older females, demonstrated a tendency to perceptions of the elderly that associated avoidance of the elderly with negative stereotypes whereas older females, in contrast to younger females, held perceptions that associated avoidance of the elderly with a negative perception of the elderly person's contribution to society. Despite cultural differences between Israel and North America, the similarity of findings provides support for the generalizabilty of the structure of attitudes toward the elderly as measured by the FSA to various cultures. In addition, the combined effect of age and gender on differential forms of ageism is complex and should be examined in future research.

Effect of heteroscedasticity treatment in residual error models on model calibration and prediction uncertainty estimation

NASA Astrophysics Data System (ADS)

Sun, Ruochen; Yuan, Huiling; Liu, Xiaoli

2017-11-01

The heteroscedasticity treatment in residual error models directly impacts the model calibration and prediction uncertainty estimation. This study compares three methods to deal with the heteroscedasticity, including the explicit linear modeling (LM) method and nonlinear modeling (NL) method using hyperbolic tangent function, as well as the implicit Box-Cox transformation (BC). Then a combined approach (CA) combining the advantages of both LM and BC methods has been proposed. In conjunction with the first order autoregressive model and the skew exponential power (SEP) distribution, four residual error models are generated, namely LM-SEP, NL-SEP, BC-SEP and CA-SEP, and their corresponding likelihood functions are applied to the Variable Infiltration Capacity (VIC) hydrologic model over the Huaihe River basin, China. Results show that the LM-SEP yields the poorest streamflow predictions with the widest uncertainty band and unrealistic negative flows. The NL and BC methods can better deal with the heteroscedasticity and hence their corresponding predictive performances are improved, yet the negative flows cannot be avoided. The CA-SEP produces the most accurate predictions with the highest reliability and effectively avoids the negative flows, because the CA approach is capable of addressing the complicated heteroscedasticity over the study basin.

Feeling loved and integrated or lonely and rejected in everyday life: The role of age and social motivation.

Social approach and social avoidance goals (i.e., approach of positive and avoidance of negative outcomes in social situations) are important predictors of the feeling of being socially integrated or isolated. However, little is known about the development of these goals across adulthood. In a large diary study with N = 744 young (18-39 years), middle-aged (40-59 years), and older adults (60-83 years), we tested the hypothesis that the adaptiveness of social goals changes across adulthood: Social approach goals were hypothesized to be adaptive during young adulthood when adult social relationships are to be established. In contrast, social avoidance goals were hypothesized to become more adaptive with age as people are increasingly motivated to avoid interpersonal tension. Our findings support these hypotheses: Social approach goals were positively and social avoidance goals negatively associated with younger but not with middle-aged and older adults' daily social well-being. These results were robust across different situations (positive, negative) and different types of relationships (close, peripheral). The study highlights the changing role of social approach and avoidance goals for daily social well-being across adulthood. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Engaging in Rather than Disengaging from Stress: Effective Coping and Perceived Control

Being able to cope effectively with stress can help people to avoid negative consequences for their psychological well-being. The purpose of this study was to find out why some coping strategies are effective in reducing the negative effect of stressors on well-being and some are not. We argue that the degree to which such coping strategies engage or disengage people from stressful incidents is related to their perceived control of the situation that, in turn, is positively associated with their psychological well-being. We thus propose that the relationship between coping and psychological well-being is mediated by the extent of perceived sense of control. We collected cross-sectional data from a large heterogeneous sample (N = 543) in the Netherlands. We assessed seven different coping strategies, perceived control, and psychological well-being. Our results indeed revealed that strategies reflecting more engaged coping such as active confronting and reassuring thoughts, were associated with more sense of control and therefore to psychological well-being. In contrast, strategies reflecting disengagement coping, such as passive reaction pattern, palliative reaction, and avoidance, were associated with less perceived control, which in turn was negatively associated with psychological well-being. Results regarding the coping strategies expressing emotions and seeking social support were less straightforward, with the former being negatively associated with perceived control and psychological well-being, even though this strategy has stress engaging elements, and the latter only showing a positive indirect effect on psychological well-being via perceived control, but no positive main effect on well-being. These findings are discussed from the perspective of stress being an environment-perception-response process. PMID:27708603

How Stereotype Threat Affects Healthy Older Adults' Performance on Clinical Assessments of Cognitive Decline: The Key Role of Regulatory Fit.

PubMed

Barber, Sarah J; Mather, Mara; Gatz, Margaret

2015-11-01

Stereotype threat can impair older adults' performance on clinical assessments for cognitive decline. We examined why this occurs. Based upon the regulatory focus account of stereotype threat, we predicted that the effects of stereotype threat should depend upon the assessments' reward structure. Stereotype threat should be associated with poor performance when the assessment emphasizes gaining correct answers, but not when it emphasizes avoiding mistakes. Healthy older adults completed a series of mental status examinations. Half of the participants completed these examinations under stereotype threat about their cognitive abilities. Monetary incentives were also manipulated. For half of the participants correct responding led to gains. For the remaining participants incorrect responding/forgetting led to losses. Consistent with the regulatory focus account, stereotype threat was associated with poor performance when the mental status examinations had a gains-based structure, but not when they had a losses-based structure. Older adults respond to stereotype threat by becoming vigilant to avoid the losses that will make them their worst. Researchers and clinicians can capitalize on this motivational change to combat stereotype threat's negative effects. By using a loss-avoidance frame, stereotype threat's negative effects can be attenuated or even eliminated. © The Author 2015.

The illicit use of anabolic androgenic steroids (AAS) has gained popularity among adolescents in the last decade. However, although it is known that exposure to AAS impairs cognition in adult animal models, the cognitive effects during adolescence remain undetermined. An inhibitory avoidance task (IAT) was used to assess the effect of AAS (17α-methyltestosterone; 17α-meT--7.5 mg/kg) in male and female periadolescent rats. A single injection of 17α-meT immediately before the footshock produced significant impairment of inhibitory avoidance learning in males but not females. Generalized anxiety, locomotion, and risk assessment behaviors (RAB) were not affected. Our results show that exposure to a single pharmacological dose of 17α-meT during periadolescence exerts sex-specific cognitive effects without affecting anxiety. Thus, disruption of the hormonal milieu during this early developmental period might have negative impact on learning and memory. Copyright © 2013 Elsevier B.V. All rights reserved.

Personality affects aspects of health-related quality of life in Parkinson's disease via psychological coping strategies.

Personality traits influence health-related quality of life (HRQoL) in Parkinson's disease (PD). Further, an individual's personality traits can influence the strategies they use to cope with a particular stressful situation. However, in PD, the interplay between personality traits, choice of coping strategy, and their subsequent effect on HRQoL remains unclear. The objective of this study was to examine whether personality (neuroticism and extraversion) indirectly affects HRQoL through the use of specific psychological coping strategies. One hundred and forty-six patients with PD completed questionnaires on personality (Big Five Aspects Scale; BFAS), coping (Ways of Coping Questionnaire; WCQ), and mood-specific (Depression, Anxiety and Stress Scale; DASS-21) and disease-specific HRQoL (Parkinson's Disease Questionnaire; PDQ-39). After controlling for gender, age at diagnosis, and age at testing, the emotion-focused coping strategy of escape-avoidance was significantly correlated with neuroticism and certain aspects of HRQoL (cognitive impairment and social support). This suggests that neurotic personality traits may negatively impact on some aspects of HRQoL due to an increased use of escape-avoidance coping strategies. By contrast, planned problem-solving and escape-avoidance coping strategies were both significantly linked to extraversion and interpersonal and mood-related domains of HRQoL. This suggests that extraversion may positively impact on some aspects of HRQoL due to patients adopting greater planned, problem-solving coping strategies, and using fewer escape-avoidance coping mechanisms. Psychological interventions aimed at targeting maladaptive coping strategies, such as the use of escape-avoidance coping, may be effective in minimising the negative impact of neuroticism on HRQoL in PD.

Fulfill Promises and Avoid Breaches to Retain Satisfied, Committed Nurses.

PubMed

Rodwell, John; Ellershaw, Julia

2016-07-01

This study examines two commonly proposed mechanisms, violation and trust, to see if they mediate the relationships between the components of the psychological contract (i.e., promises, fulfillment, and breach) and their impact on the work-related outcomes of job satisfaction, intent to quit, and organizational commitment. Online surveys were completed by 459 Australian nurses. Structural equation modeling revealed that breach and fulfillment have direct and mediated effects on the outcomes, whereas promises had no impact. Violation partially mediated the relationship between breach and job satisfaction and intent to quit, while trust partially mediated the relationships between fulfillment and organizational commitment, and breach and organizational commitment. Negative experiences (i.e., breaches) were related to both increased feelings of violation and decreased feelings of trust. In contrast, positive experiences (i.e., fulfillment) increased trust but did not significantly reduce feelings of violation. Nurse and organizational managers can use these findings to improve communication with nurses so as to minimize the negative effects of breach and maximize the positive effects of fulfillment and thus improve attitudes. Nurse managers need to be careful to make promises regarding their nurses' employment that they can fulfill and to particularly avoid breaking the psychological contract. The potentially disproportionate negative effect of breach means that a breach can undo a lot of efforts to fulfill employment-related promises. © 2016 Sigma Theta Tau International.

Are positive and negative reinforcement "different"? Insights from a free-operant differential outcomes effect.

Although theoretical discussions typically assume that positive and negative reinforcement differ, the literature contains little unambiguous evidence that they produce differential behavioral effects. To test whether the two types of consequences control behavior differently, we pitted money-gain positive reinforcement and money-loss-avoidance negative reinforcement, scheduled through identically programmed variable-cycle schedules, against each other in concurrent schedules. Contingencies of response-produced feedback, normally different in positive and negative reinforcement, were made symmetrical. Steeper matching slopes were produced compared to a baseline consisting of all positive reinforcement. This free-operant differential outcomes effect supports the notion that that stimulus-presentation positive reinforcement and stimulus-elimination negative reinforcement are functionally "different." However, a control experiment showed that the feedback asymmetry of more traditional positive and negative reinforcement schedules also is sufficient to create a "difference" when the type of consequence is held constant. We offer these findings as a small step in meeting the very large challenge of moving negative reinforcement theory beyond decades of relative quiescence. © 2017 Society for the Experimental Analysis of Behavior.

The association between fear of cancer recurrence and quality of life among Chinese cancer survivors: main effect hypothesis and buffering hypothesis.

PubMed

Cho, Dalnim; Lu, Qian

2017-09-01

The aim of the present study is to examine whether fear of cancer recurrence (FCR) is related to health-related quality of life (HRQOL) among Chinese cancer survivors, an understudied population (i.e., main effect hypothesis). Also, we investigated whether the FCR-HRQOL link is moderated by two coping strategies, avoidance and positive reappraisal (i.e., buffering hypothesis). This is a cross-sectional study conducted among 238 Chinese cancer survivors in Beijing. Participants completed a set of questionnaires including FCR, coping, and HRQOL. FCR was related to lower physical, psychological, social, and spiritual well-beings, even when demographics, cancer-related factors, and coping were taken into account. There was only one moderation effect between FCR and avoidance coping. Surprisingly, the detrimental effect of FCR on spiritual well-being was lessened among those with high avoidance coping such that the negative association between FCR and spiritual well-being was only found in those with low avoidance coping and not among those with high avoidance coping. Findings largely supported the main effect hypothesis. FCR was associated with diverse domains of HRQOL among Chinese cancer survivors. The buffering hypothesis was largely not supported in this population. Rather, in some cases, the effects of FCR and coping strategies on HRQOL were independent. Thus, ways to attenuate the harmful effects of FCR on HRQOL among Chinese cancer survivors remain unresolved. It is urgent and timely that future studies focus on FCR and HRQOL in this population.

Internalized societal attitudes moderate the impact of weight stigma on avoidance of exercise.

Vartanian, Lenny R; Novak, Sarah A

2011-04-01

Experiences with weight stigma negatively impact both psychological outcomes (e.g., body dissatisfaction, depression) and behavioral outcomes (e.g., dieting, exercise). However, not everyone is equally affected by experiences with weight stigma. This study examined whether internalized societal attitudes about weight moderated the impact of weight stigma. Adult participants (n = 111) completed measures of experiences with weight stigma, as well as two indexes of internalized societal attitudes (the moderators): Internalized anti-fat attitudes and internalization of societal standards of attractiveness. Psychological outcomes included self-esteem, body dissatisfaction, drive for thinness, and bulimic symptoms; behavioral outcomes included avoidance of exercise and self-reported exercise behavior. Weight stigma was positively correlated with body dissatisfaction, drive for thinness, and bulimic symptoms, and was negatively correlated with state and trait self-esteem. Both indexes of internalized attitudes moderated the association between weight stigma and avoidance of exercise: Individuals high in anti-fat attitudes and high in internalization of societal standards of attractiveness were more motivated to avoid exercise if they also experienced a high degree of weight stigma; individuals low in anti-fat attitudes and low in internalization were relatively unaffected. Avoidance of exercise was negatively correlated with self-reported strenuous exercise. These findings suggest that weight stigma can negatively influence motivation to exercise, particularly among individuals who have internalized societal attitudes about weight. Reducing internalization might be a means of minimizing the negative impact of weight stigma and of facilitating healthy weight management efforts.

Automatic and controlled attentional orienting in the elderly: A dual-process view of the positivity effect.

2018-04-01

The positivity effect in the elderly consists of an attentional preference for positive information as well as avoidance of negative information. Extant theories predict either that the positivity effect depends on controlled attentional processes (socio-emotional selectivity theory), or on an automatic gating selection mechanism (dynamic integration theory). This study examined the role of automatic and controlled attention in the positivity effect. Two dot-probe tasks (with the duration of the stimuli lasting 100 ms and 500 ms, respectively) were employed to compare the attentional bias of 35 elderly people to that of 35 young adults. The stimuli used were expressive faces displaying neutral, disgusted, fearful, and happy expressions. In comparison to young people, the elderly allocated more attention to happy faces at 100 ms and they tended to avoid fearful faces at 500 ms. The findings are not predicted by either theory taken alone, but support the hypothesis that the positivity effect in the elderly is driven by two different processes: an automatic attention bias toward positive stimuli, and a controlled mechanism that diverts attention away from negative stimuli.

A daily process examination of episode-specific drinking to cope motivation among college students.

Theory suggests that state- and trait-like factors should interact in predicting drinking to cope (DTC) motivation, yet no research to date has demonstrated this at the drinking episode level of analysis. Thus, we examined whether daily variation in positive and negative affect and avoidance and active coping were associated with DTC motivation during discrete drinking episodes and whether these associations were moderated by tension-reduction expectancies and other person-level risk factors. Using a secure website, 722 college student drinkers completed a one-time survey regarding their tension reduction expectancies and then reported daily for 30 days on their affect, coping strategies, drinking behaviors and motives for drinking. Individuals reported higher levels of DTC motivation on days when negative affect and avoidance coping were high and positive affect was low. We found only little support for the predicted interactive effects among the day- and person-level predictors. Our results support the state and trait conceptualizations of DTC motivation and provide evidence for the antecedent roles of proximal levels of daily affect and avoidance coping. Our inconsistent results for interaction effects including day-level antecedents raise the possibility that some of these synergistic processes might not generalize across level of analysis.

Negative reinforcement results in behavior to escape or avoid an aversive outcome. Withdrawal symptoms are purported to be negative reinforcers in perpetuating substance dependence, but little is known about negative reinforcement learning in this population. The purpose of this study was to examine reinforcement learning in substance dependent individuals (SDI), with an emphasis on assessing negative reinforcement learning. We modified the Iowa Gambling Task to separately assess positive and negative reinforcement. We hypothesized that SDI would show differences in negative reinforcement learning compared to controls and we investigated whether learning differed as a function of the relative magnitude or frequency of the reinforcer. Thirty subjects dependent on psychostimulants were compared with 28 community controls on a decision making task that manipulated outcome frequencies and magnitudes and required an action to avoid a negative outcome. SDI did not learn to avoid negative outcomes to the same degree as controls. This difference was driven by the magnitude, not the frequency, of negative feedback. In contrast, approach behaviors in response to positive reinforcement were similar in both groups. Our findings are consistent with a specific deficit in negative reinforcement learning in SDI. SDI were relatively insensitive to the magnitude, not frequency, of loss. If this generalizes to drug-related stimuli, it suggests that repeated episodes of withdrawal may drive relapse more than the severity of a single episode. Copyright © 2011 Elsevier Ireland Ltd.

This research builds on terror management theory to examine the relationships among self-esteem, death cognition, and psychological adjustment. Self-esteem was measured (Studies 1-2, 4-8) or manipulated (Study 3), and thoughts of death were manipulated (Studies 1-3, 5-8) or measured (Study 4). Subsequently, satisfaction with life (Study 1), subjective vitality (Study 2), meaning in life (Studies 3-5), positive and negative affect (Studies 1, 4, 5), exploration (Study 6), state anxiety (Study 7), and social avoidance (Study 8) were assessed. Death-related cognition (a) decreased satisfaction with life, subjective vitality, meaning in life, and exploration; (b) increased negative affect and state anxiety; and (c) exacerbated social avoidance for individuals with low self-esteem but not for those with high self-esteem. These effects occurred only when death thoughts were outside of focal attention. Parallel effects were found in American (Studies 1-4, 6-8) and Chinese (Study 5) samples.

Reversing one's fortune by pushing away bad luck.

PubMed

Zhang, Yan; Risen, Jane L; Hosey, Christine

2014-06-01

Across cultures, people try to "undo" bad luck with superstitious rituals such as knocking on wood, spitting, or throwing salt. We suggest that these rituals reduce the perceived likelihood of anticipated negative outcomes because they involve avoidant actions that exert force away from one's representation of self, which simulates the experience of pushing away bad luck. Five experiments test this hypothesis by having participants tempt fate and then engage in avoidant actions that are either superstitious (Experiment 1, knocking on wood) or nonsuperstitious (Experiments 2-5, throwing a ball). We find that participants who knock down (away from themselves) or throw a ball think that a jinxed negative outcome is less likely than participants who knock up (toward themselves) or hold a ball. Experiments 3 and 4 provide evidence that after tempting fate, engaging in an avoidant action leads to less clear mental representations for the jinxed event, which, in turn, leads to lower perceived likelihoods. Finally, we demonstrate that engaging in an avoidant action-rather than creating physical distance-is critical for reversing the perceived effect of the jinx. Although superstitions are often culturally defined, the underlying psychological processes that give rise to them may be shared across cultures.

Individuals are frequently faced with risky decisions involving the potential for both gain and loss. Exploring the role of both potential gains and potential losses in predicting risk taking is critical to understanding how adolescents and adults make the choice to engage in or avoid a real-life risk. This study aimed to examine the impact of potential losses as well as gains on adolescent decisions during risky choice in a laboratory task. Adolescent (n=18) and adult (n=16) participants underwent functional magnetic resonance imaging (fMRI) during a mixed gambles task, and completed questionnaires measuring real-world risk-taking behaviors. While potential loss had a significantly greater effect on choice than potential gain in both adolescents and adults and there were no behavioral group differences on the task, adolescents recruited significantly more frontostriatal circuitry than adults when choosing to reject a gamble. During risk-seeking behavior, adolescent activation in medial prefrontal cortex (mPFC) was negatively correlated with self-reported likelihood of risk taking. During risk-avoidant behavior, mPFC activation of in adults was negatively correlated with self-reported benefits of risk-taking. Taken together, these findings reflect different neural patterns during risk-taking and risk-avoidant behaviors in adolescents and adults. Copyright © 2012 Elsevier Ltd. All rights reserved.

Women are underrepresented in emergency medicine (EM) residency programs in comparison with many other specialties. The reasons for this are unclear. One hypothesis is that negative gender stereotypes about EM careers might exist among female medical students. In the field of education, negative gender stereotypes are known to lead to career avoidance, because they tend to decrease self-efficacy perception. The aims of this study were to assess the prevalence of negative gender stereotypes about EM practice among medical students and to measure the effects of these stereotypes on females' self-efficacy perception toward EM learning. A survey was conducted of the 255 third-year medical students from three medical schools who attended a mandatory EM academic program in France. They completed an anonymous questionnaire exploring their gender stereotypes about EM practice and their self-efficacy perception toward EM learning. Gender stereotypes are common among medical students, especially in women. Self-efficacy perception is negatively correlated to female students' belief that EM careers are better suited for men (p < 0.05). Negative gender stereotypes among female medical students may lead to EM career avoidance, because of the decrease in their self-efficacy perception toward EM learning. 2010 by the Society for Academic Emergency Medicine

Memories relating to a painful, negative event are adaptive and can be stored for a lifetime to support preemptive avoidance, escape, or attack behavior. However, under unfavorable circumstances such memories can become overwhelmingly powerful. They may trigger excessively negative psychological states and uncontrollable avoidance of locations, objects, or social interactions. It is therefore obvious that any process to counteract such effects will be of value. In this context, we stress from a basic-research perspective that painful, negative events are “Janus-faced” in the sense that there are actually two aspects about them that are worth remembering: What made them happen and what made them cease. We review published findings from fruit flies, rats, and man showing that both aspects, respectively related to the onset and the offset of the negative event, induce distinct and oppositely valenced memories: Stimuli experienced before an electric shock acquire negative valence as they signal upcoming punishment, whereas stimuli experienced after an electric shock acquire positive valence because of their association with the relieving cessation of pain. We discuss how memories for such punishment- and relief-learning are organized, how this organization fits into the threat-imminence model of defensive behavior, and what perspectives these considerations offer for applied psychology in the context of trauma, panic, and nonsuicidal self-injury.

Constructive and Unproductive Processing of Traumatic Experiences in Trauma-Focused Cognitive-Behavioral Therapy for Youth.

2017-03-01

Although there is substantial evidence to support the efficacy of cognitive-behavioral treatments (CBT) for posttraumatic stress disorder (PTSD), there is some debate about how these treatments have their effects. Modern learning theory and cognitive and emotional processing theories highlight the importance of reducing avoidance, facilitating the constructive processing of feared experiences, and strengthening new inhibitory learning. We examined variables thought to be associated with unproductive and constructive processing of traumatic experiences in a sample of 81 youth with elevated PTSD symptoms, who received Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) for abuse or traumatic interpersonal loss. Sessions during the trauma narrative phase of TF-CBT were coded for indicators of unproductive processing (overgeneralization, rumination, avoidance) and constructive processing (decentering, accommodation of corrective information), as well as levels of negative emotion. In previous analyses of this trial (Ready et al., 2015), more overgeneralization during the narrative phase predicted less improvement in internalizing symptoms at posttreatment and a worsening of externalizing symptoms over the 12-month follow-up. In contrast, more accommodation predicted improvement in internalizing symptoms and also moderated the negative effects of overgeneralization on internalizing and externalizing symptoms. The current study examined correlates of overgeneralization and accommodation. Overgeneralization was associated with more rumination, less decentering, and more negative emotion, suggesting immersion in trauma-related material. Accommodation was associated with less avoidance and more decentering, suggesting a healthy distance from trauma-related material that might allow for processing and cognitive change. Decentering also predicted improvement in externalizing symptoms at posttreatment. Rumination and avoidance showed important associations with overgeneralization and accommodation, respectively, but did not predict treatment outcomes. This study identifies correlates of overgeneralization and accommodation that might shed light on how these variables relate to unproductive and constructive processing of traumatic experiences.

The Precautionary Principle and Electric and Magnetic Fields

PubMed Central

Jamieson, Dale; Wartenberg, Daniel

2001-01-01

Current environmental regulation represents a paternalistic policy, more concerned to avoid false positives than false negatives, limiting opportunities for individuals to make choices between risk-avoidance and risk-taking alternatives. For example, many exposures to magnetic fields could be reduced at little or no cost but are not considered seriously, owing to the uncertainty of risk and the concern to avoid false positives. Even though precautionary approaches that focus on avoiding false negatives often do not lead to adverse economic consequences or irrational choices, such approaches usually are not taken. The value of autonomy and the proper role of governmental paternalism with respect to environmental policy need to be considered more carefully in environmental decision making. PMID:11527754

Attentional focus during exposure in spider phobia: The effect of valence and schematicity of a partial distractor.

PubMed

Dethier, Vincent; Philippot, Pierre

2017-06-01

This study examines the impact of partial distractor valence and schematicity (i.e., their relation to fear representation) on exposure efficacy. One hundred forty-one spider phobics were exposed to spider pictures and asked, in a between-subjects experimental design, to form mental images of words that were fear related (to spiders) and negative (schematic negative), fear unrelated and negative (non-schematic negative) or fear unrelated and positive (non-schematic positive). Multilevel measures of anxiety were performed at pre-exposure, post-exposure and 6 days' follow-up. Results show that both of the negative condition groups displayed similar results on all outcome variables and systematically differed from the positive condition group. While the latter group displayed a stronger decline in distress during exposure itself, the other groups showed greater exposure benefits: a stronger decline in emotional and avoidance responses and skin conductance responses from pre- to post-exposure and more approach behaviours when confronted with a real spider. The critical feature of distraction thus seems not to be the fact of being distracted from the phobic stimulus, but rather the fact of performing emotional avoidance by distracting oneself from negative affect. The results highlight that the acceptance of aversive emotional states is a critical active process in successful exposure. Copyright © 2017 Elsevier Ltd. All rights reserved.

Attentional effects of masked famous faces (but not names) and subjective evaluations of a target person.

PubMed

Stone, Anna

2011-04-01

Two experiments are reported using a 1986 version of the dot-probe paradigm of MacLeod, Mathews, and Tata, in which the masked subliminal faces of famous persons were differentially associated with attention depending on participants' attitudes toward the famous person. There was attentional avoidance of the faces of persons invoking high disgust (Exp. 1, n=20) or dislike (Exp. 2) but attentional orientation toward the faces of persons invoking low disgust or liking. In Exp. 2 (n=28), this effect was apparent for the faces but not the names of famous persons, despite evidence that the famous names were recognised without awareness. The aversion of attention from faces, but not the names of famous persons who are regarded in a negative light but who are not particularly threatening, may suggest an automatic tendency to avoid making eye contact with an undesirable person thereby avoiding unwanted social interaction.

The study was conducted with 388 students using the 3 × 2 Achievement Goal Questionnaire including the six proposed goal constructs (task-approach, task-avoidance, self-approach, self-avoidance, other-approach, other-avoidance) and the enjoyment and boredom scales from the Achievement Emotion Questionnaire. Exam grades were used as an indicator of academic achievement. Findings from CFAs provided strong support for the proposed structure of the 3 × 2 achievement goal model. Self-based goals, other-based goals and task-approach goals predicted enjoyment. Task-approach goals negatively predicted boredom. Task-approach and other-approach predicted achievement. The indirect effects of achievement goals through emotion variables on achievement were assessed using bias-corrected bootstrapping. No mediation effects were found. Implications for educational practice are discussed. PMID:27199836

BACKGROUND Individual physicians who are paid prospectively, as in capitated health plans, might tend to encourage patients to avoid or to join these plans according to the patient's health status. Though insurance risk selection has been well documented among organizations paid on a prospective basis, such physician-level risk selection has not been studied. OBJECTIVE To assess physician reports of risk selection in capitated health plans and explore potentially related factors. DESIGN AND PARTICIPANTS National mailed survey of primary care physicians in 1997–1998, oversampling physicians in areas with more capitated health plans. RESULTS The response rate was 63% (787 of 1,252 eligible recipients). Overall, 44% of physicians reported encouraging patients either to join or to avoid capitated health plans according to the patients' health status: 40% encouraged more complex and ill patients to avoid capitated plans and 23% encouraged healthier patients to join capitated plans. In multivariable models, physicians with negative perceptions of capitated plan quality, with more negative experiences in capitated plans, and those who knew at each patient encounter how they were being compensated had higher odds of encouraging sicker patients to avoid capitated plans (odds ratios, 2.0, 2.2, and 2.0; all confidence intervals >1). CONCLUSIONS Many primary care physicians report encouraging patients to join or avoid capitated plans according to the patient's health status. Although these physicians' recommendations might be associated primarily with concerns about quality, they can have the effect of insulating certain health plans from covering sicker and more expensive patients.

Research on mental health following disasters has led to the identification of many individual protective and risk factors for postdisaster mental health. However, there is little understanding of the exact influence that disasters have on the functioning of intimate relationships. Especially relevant are attachment styles, which are likely to play an important role in the provision and perception of social support between partners, and subsequent mental health outcomes. Heterosexual couples (N = 127) affected by the 2009 Victorian "Black Saturday" Bushfires in southeastern Australia were surveyed for disaster experiences, posttraumatic stress disorder (PTSD) symptoms, depression, and attachment style between May 2012 and January 2013, approximately 3 years after the disaster. Using actor-partner interdependence models (APIM), we examined both intrapersonal and interpersonal associations of attachment anxiety and avoidance with depression and PTSD, in combination with shared disaster exposure. Male partners' attachment avoidance was associated with depression and PTSD in both partners. By contrast, a female partner's attachment avoidance was associated with greater depression and PTSD in herself, but fewer PTSD symptoms in a male partner. Amid the chronic stressors of a postdisaster setting, the attachment avoidance of the male partner may play a particularly negative role, with his tendency toward isolation and denial becoming especially maladaptive for the couple as a whole. The female partner's attachment avoidance is likewise an important factor, but its associations with negative social support and relationship breakup must be clarified to understand its impact on partnership functioning.

Associating crash avoidance maneuvers with driver attributes and accident characteristics: a mixed logit model approach.

PubMed

Kaplan, Sigal; Prato, Carlo Giacomo

2012-01-01

The current study focuses on the propensity of drivers to engage in crash avoidance maneuvers in relation to driver attributes, critical events, crash characteristics, vehicles involved, road characteristics, and environmental conditions. The importance of avoidance maneuvers derives from the key role of proactive and state-aware road users within the concept of sustainable safety systems, as well as from the key role of effective corrective maneuvers in the success of automated in-vehicle warning and driver assistance systems. The analysis is conducted by means of a mixed logit model that represents the selection among 5 emergency lateral and speed control maneuvers (i.e., "no avoidance maneuvers," "braking," "steering," "braking and steering," and "other maneuvers) while accommodating correlations across maneuvers and heteroscedasticity. Data for the analysis were retrieved from the General Estimates System (GES) crash database for the year 2009 by considering drivers for which crash avoidance maneuvers are known. The results show that (1) the nature of the critical event that made the crash imminent greatly influences the choice of crash avoidance maneuvers, (2) women and elderly have a relatively lower propensity to conduct crash avoidance maneuvers, (3) drowsiness and fatigue have a greater negative marginal effect on the tendency to engage in crash avoidance maneuvers than alcohol and drug consumption, (4) difficult road conditions increase the propensity to perform crash avoidance maneuvers, and (5) visual obstruction and artificial illumination decrease the probability to carry out crash avoidance maneuvers. The results emphasize the need for public awareness campaigns to promote safe driving style for senior drivers and warning about the risks of driving under fatigue and distraction being comparable to the risks of driving under the influence of alcohol and drugs. Moreover, the results suggest the need to educate drivers about hazard perception, designing a forgiving infrastructure within a sustainable safety systems, and rethinking in-vehicle collision warning systems. Future research should address the effectiveness of crash avoidance maneuvers and joint modeling of maneuver selection and crash severity.

Implicit attitudes have been shown to predict smoking behaviors. Therefore, an important goal is the development of interventions to change these attitudes. This study assessed the effects of a web-based intervention on implicit attitudes toward smoking and receptivity to smoking-related information. Smokers (N = 284) were recruited to a two-session web-based study. In the first session, baseline data were collected. Session two contained the intervention, which consisted of assignment to the experimental or control version of an approach-avoidance task and assignment to an anti-smoking or control public service announcement (PSA), and post-intervention measures. Among smokers with less education and with plans to quit, implicit attitudes were more negative for those who completed the approach-avoidance task. Smokers with more education who viewed the anti-smoking PSA and completed the approach-avoidance task spent more time reading smoking-related information. An approach-avoidance task is a potentially feasible strategy for changing implicit attitudes toward smoking and increasing receptivity to smoking-related information.

To examine factors in the fear-avoidance model, such as pain, pain catastrophizing, fear-avoidance beliefs, physical disability, and depression and their relationships with physical and psychological quality of life in patients with rheumatic diseases. The data were obtained from 360 patients with rheumatic diseases who completed self-report measures assessing study variables. Structural equation modeling was used to examine the hypothesized relationships among factors specified in the fear-avoidance model predicting physical and psychological quality of life. Final models fit the data well, explaining 96% and 82% of the variance in physical and psychological quality of life, respectively. Higher pain catastrophizing was related to stronger fear-avoidance beliefs that had a direct negative association with physical disability and depression, which, in turn, negatively affected physical quality of life. Pain severity was also directly related to physical disability. Physical disability also affected physical quality of life indirectly through depression. The hypothesized relationships specified in the model were also confirmed for psychological quality of life. However, physical disability had an indirect association with psychological quality of life via depression. The current results underscore the significant role of cognitive, affective, and behavioral factors in perceived physical disability and their mediated detrimental effect on physical and psychological quality of life in patients with rheumatic diseases. Implications for rehabilitation The fear-avoidance model is applicable to the prediction of quality of life in patients with rheumatic diseases. As pain-catastrophizing and fear-avoidance beliefs are important factors linked to physical disability and depression, intervening these cognitive factors is necessary to improve physical function and depression in patients with rheumatic diseases. Considering the strong association between depression and physical and psychological quality of life, the assessment and treatment of the former should be included in the rehabilitation of patients with rheumatic diseases. Interventions targeting physical function and depression are likely to be effective in terms of improving physical and psychological quality of life in patients with rheumatic diseases.

Increasing evidence indicates that eye gaze direction affects the processing of emotional faces in anxious individuals. However, the effects of eye gaze direction on the behavioral responses elicited by emotional faces, such as avoidance behavior, remain largely unexplored. We administered an Approach-Avoidance Task (AAT) in high (HSA) and low socially anxious (LSA) individuals. All participants responded to photographs of angry, happy and neutral faces (presented with direct and averted gaze), by either pushing a joystick away from them (avoidance) or pulling it towards them (approach). Compared to LSA, HSA were faster in avoiding than approaching angry faces. Most crucially, this avoidance tendency was only present when the perceived anger was directed towards the subject (direct gaze) and not when the gaze of the face-stimulus was averted. In contrast, HSA individuals tended to avoid happy faces irrespectively of gaze direction. Neutral faces elicited no approach-avoidance tendencies. Thus avoidance of angry faces in social anxiety as measured by AA-tasks reflects avoidance of subject-directed anger and not of negative stimuli in general. In addition, although both anger and joy are considered to reflect approach-related emotions, gaze direction did not affect HSA's avoidance of happy faces, suggesting differential mechanisms affecting responses to happy and angry faces in social anxiety. 2009 Elsevier Ltd.

The authors investigated the effects on job performance of 3 forms of goal orientation and 4 self-regulation (SR) tactics. In a longitudinal field study with salespeople, learning and performance-prove goal orientation predicted subsequent sales performance, whereas performance-avoid goal orientation negatively predicted sales performance. The SR tactics functioned as mediating variables between learning and performance-prove goal orientations and performance. Social competence and proactive behavior directly and positively predicted sales performance, and emotional control negatively predicted performance. (c) 2006 APA, all rights reserved.

The present study examines a mediated moderation model of the effects of conscientiousness and coping strategies on the relationship between abusive supervision and employees' job performance. Across 2 studies conducted in India, we found evidence that the relationship between abusive supervision and job performance was weaker when employees were high in conscientiousness. In addition, we found that the use of an avoidance coping strategy facilitated a negative relationship between abusive supervision and performance. Finally, we found that the moderating effects of conscientiousness were mediated by the use of avoidance coping strategies. Our findings contribute to theories of abusive supervision, personality, coping strategies, and job performance. PsycINFO Database Record (c) 2014 APA, all rights reserved

The behavioral effects of emotional negative stress (immobilization) were studied in Wistar rats intact and those that had previous positive emotion experience. The food-getting learning has been chosen as positive emotion experience. Animals were trained in food pellet-reaching task by their preferred paw. It was shown that immobilization of intact rats leads to suppression of motor activity and increasing the duration of grooming. These effects indicate enhancement of passive-avoidance reactions. It was also shown that motor learning in group of rats with food reinforcement before immobilisation significantly reduces appearance of passive-avoidance reactions. It was found that immobilization stress does not inverse the initial direction of limb preference in majority of rats.

Animal to human translational paradigms relevant for approach avoidance conflict decision making.

2017-09-01

Avoidance behavior in clinical anxiety disorders is often a decision made in response to approach-avoidance conflict, resulting in a sacrifice of potential rewards to avoid potential negative affective consequences. Animal research has a long history of relying on paradigms related to approach-avoidance conflict to model anxiety-relevant behavior. This approach includes punishment-based conflict, exploratory, and social interaction tasks. There has been a recent surge of interest in the translation of paradigms from animal to human, in efforts to increase generalization of findings and support the development of more effective mental health treatments. This article briefly reviews animal tests related to approach-avoidance conflict and results from lesion and pharmacologic studies utilizing these tests. We then provide a description of translational human paradigms that have been developed to tap into related constructs, summarizing behavioral and neuroimaging findings. Similarities and differences in findings from analogous animal and human paradigms are discussed. Lastly, we highlight opportunities for future research and paradigm development that will support the clinical utility of this translational work. Copyright © 2017 Elsevier Ltd. All rights reserved.

Mad genius revisited: Vulnerability to psychopathology, biobehavioral approach-avoidance, and creativity.

Baas, Matthijs; Nijstad, Bernard A; Boot, Nathalie C; De Dreu, Carsten K W

2016-06-01

Although many believe that creativity associates with a vulnerability to psychopathology, research findings are inconsistent. Here we address this possible linkage between risk of psychopathology and creativity in nonclinical samples. We propose that propensity for specific psychopathologies can be linked to basic motivational approach and avoidance systems, and that approach and avoidance motivation differentially influences creativity. Based on this reasoning, we predict that propensity for approach-based psychopathologies (e.g., positive schizotypy and risk of bipolar disorder) associates with increased creativity, whereas propensity for avoidance-based psychopathologies (e.g., anxiety, negative schizotypy, and depressive mood) associates with reduced creativity. Previous meta-analyses resonate with this proposition and showed small positive relations between positive schizotypy and creativity and small negative relations between negative schizotypy and creativity and between anxiety and creativity. To this we add new meta-analytic findings showing that risk of bipolar disorder (e.g., hypomania, mania) positively associates with creativity (k = 28, r = .224), whereas depressive mood negatively associates (albeit weakly) with creativity (k = 39, r = -.064). Our theoretical framework, along with the meta-analytic results, indicates when and why specific psychopathologies, and their inclinations, associate with increased or, instead, reduced creativity.

Background Sex differences are present in many neuropsychiatric conditions that affect emotion and approach-avoidance behavior. One potential mechanism underlying such observations is testosterone in early development. Although much is known about the effects of testosterone in adolescence and adulthood, little is known in humans about how testosterone in fetal development influences later neural sensitivity to valenced facial cues and approach-avoidance behavioral tendencies. Methods With functional magnetic resonance imaging we scanned 25 8–11-year-old children while viewing happy, fear, neutral, or scrambled faces. Fetal testosterone (FT) was measured via amniotic fluid sampled between 13 and 20 weeks gestation. Behavioral approach-avoidance tendencies were measured via parental report on the Sensitivity to Punishment and Sensitivity to Rewards questionnaire. Results Increasing FT predicted enhanced selectivity for positive compared with negatively valenced facial cues in reward-related regions such as caudate, putamen, and nucleus accumbens but not the amygdala. Statistical mediation analyses showed that increasing FT predicts increased behavioral approach tendencies by biasing caudate, putamen, and nucleus accumbens but not amygdala to be more responsive to positive compared with negatively valenced cues. In contrast, FT was not predictive of behavioral avoidance tendencies, either through direct or neurally mediated paths. Conclusions This work suggests that testosterone in humans acts as a fetal programming mechanism on the reward system and influences behavioral approach tendencies later in life. As a mechanism influencing atypical development, FT might be important across a range of neuropsychiatric conditions that asymmetrically affect the sexes, the reward system, emotion processing, and approach behavior.

Family functioning is associated with adaptation in pediatric illness. This study examines the role of parents’ relationships (specifically romantic attachment) as a predictor of family ritual meaning and family cohesion for parents and their children with cancer. The dyads, 58 partnered Portuguese parents and their children in treatment, reported on family ritual meaning and family cohesion at Time 1 (T1) and after 6 months (T2). Parents also completed the questionnaire assessing romantic attachment at T1. Parents’ avoidant attachment, but not anxious attachment, predicted lower family ritual meaning and family cohesion after 6 months. T2 family ritual meaning mediated the relationship between T1 avoidant attachment and T2 family cohesion. Parents’ avoidant attachment may have a negative effect on family functioning in parents and children. Clinical intervention to address avoidant attachment or/and to promote family ritual meaning may help strengthen family ties.

This study examined 241 early adolescents' implicit and explicit associations with popularity. The peer status and gender of both the targets and the perceivers were considered. Explicit associations with popularity were assessed with sociometric methods. Implicit associations with popularity were assessed with an approach-avoidance task (AAT). Explicit evaluations of popularity were positive, but implicit associations were negative: Avoidance reactions to popular peers were faster than approach reactions. Interactions with the status of the perceiver indicated that unpopular participants had stronger negative implicit reactions to popular girls than did popular participants. This study demonstrated a negative reaction to popularity that cannot be revealed with explicit methods. The study of implicit processes with methods such as the AAT is a new and important direction for peer relations research.

Alterations in frontal and striatal function are hypothesized to underlie risky decision making in drug users, but how these regions interact to affect behavior is incompletely understood. We used mediation analysis to investigate how prefrontal cortex and ventral striatum together influence risk avoidance in abstinent drug users. Thirty-seven abstinent substance-dependent individuals (SDI) and 43 controls underwent fMRI while performing a decision-making task involving risk and reward. Analyses of a priori regions-of-interest tested whether activity in dorsolateral prefrontal cortex (DLPFC) and ventral striatum (VST) explained group differences in risk avoidance. Whole-brain analysis was conducted to identify brain regions influencing the negative VST-risk avoidance relationship. Right DLPFC (RDLPFC) positively mediated the group-risk avoidance relationship (p < 0.05); RDLPFC activity was higher in SDI and predicted higher risk avoidance across groups, controlling for SDI vs. Conversely, VST activity negatively influenced risk avoidance (p < 0.05); it was higher in SDI, and predicted lower risk avoidance. Whole-brain analysis revealed that, across group, RDLPFC and left temporal-parietal junction positively (p ≤ 0.001) while right thalamus and left middle frontal gyrus negatively (p < 0.005) mediated the VST activity-risk avoidance relationship. RDLPFC activity mediated less risky decision making while VST mediated more risky decision making across drug users and controls. These results suggest a dual pathway underlying decision making, which, if imbalanced, may adversely influence choices involving risk. Modeling contributions of multiple brain systems to behavior through mediation analysis could lead to a better understanding of mechanisms of behavior and suggest neuromodulatory treatments for addiction.

Rejection Sensitivity and Depression: Indirect Effects Through Problem Solving.

PubMed

Kraines, Morganne A; Wells, Tony T

2017-01-01

Rejection sensitivity (RS) and deficits in social problem solving are risk factors for depression. Despite their relationship to depression and the potential connection between them, no studies have examined RS and social problem solving together in the context of depression. As such, we examined RS, five facets of social problem solving, and symptoms of depression in a young adult sample. A total of 180 participants completed measures of RS, social problem solving, and depressive symptoms. We used bootstrapping to examine the indirect effect of RS on depressive symptoms through problem solving. RS was positively associated with depressive symptoms. A negative problem orientation, impulsive/careless style, and avoidance style of social problem solving were positively associated with depressive symptoms, and a positive problem orientation was negatively associated with depressive symptoms. RS demonstrated an indirect effect on depressive symptoms through two social problem-solving facets: the tendency to view problems as threats to one's well-being and an avoidance problem-solving style characterized by procrastination, passivity, or overdependence on others. These results are consistent with prior research that found a positive association between RS and depression symptoms, but this is the first study to implicate specific problem-solving deficits in the relationship between RS and depression. Our results suggest that depressive symptoms in high RS individuals may result from viewing problems as threats and taking an avoidant, rather than proactive, approach to dealing with problems. These findings may have implications for problem-solving interventions for rejection sensitive individuals.

Self-regulation as a moderator of the relation between coping and symptomatology in children of divorce.

Lengua, L J; Sandler, I N

1996-12-01

Investigated the effects of self-regulation as a moderator of the relations between coping efforts and psychological symptoms of children of divorce. The interactions of two dimensions of self-regulation (task orientation and approach-flexibility) and two dimensions of coping (active and avoidant) predicting children's postdivorce symptoms were tested using a sample of 199 divorced mothers and their children, ages 8 to 12. The approach-flexibility dimension moderated the relations of both active and avoidant coping with children's self-report of anxiety. At higher levels of approach-flexibility, active coping was negatively related to anxiety, while at lower levels of approach-flexibility, active coping was unrelated to anxiety. Avoidant coping was unrelated to anxiety at higher levels of approach-flexibility, whereas at lower levels of approach-flexibility, avoidant coping was positively related to anxiety. The task orientation dimension did not interact with coping, but had direct, independent effects on children's self-report of conduct problems, depression, and parent-report of internalizing and externalizing behavior problems. The implications for understanding children's coping with divorce and future directions for research are discussed.

The need for performing axillary lymph-node dissection in early breast cancer when the sentinel lymph node (SLN) is positive has been questioned in recent years. The purpose of this study was to identify a low-risk subgroup of early breast cancer patients in whom surgical axillary staging could be avoided, and to assess the probability of having a positive lymph-node (LN). We evaluated the cohort of 612 consecutive women affected by early breast cancer. We considered age, tumor size, histological grade, vascular invasion, lymphatic invasion and cancer subtype (Luminal A, Luminal B HER-2+, Luminal B HER-2-, HER-2+, and Triple Negative) as variables for univariate and multivariate analyses to assess probability of there being a positive SLN o nonsentinel lymph node (NSLN). Chi-square, Fisher's Exact test and Student's t tests were used to investigate the relationship between variables; whereas logit models were used to estimate and quantify the strength of the relationship among some covariates and SLN or the number of metastases. A significant positive effect of vascular invasion and lymphatic invasion (odds ratios are 4 and 6), and a negative effect of TN (odds ratios is 10) were noted. With respect to positive NSLN, size alone has a significant (positive) effect on tumor presence, but focusing on the number of metastases, also age has a (negative) significant effect. This work shows correlation between subtypes and the probability of having positive SLN. Patients not expressing vascular invasion, lymphatic invasion and, moreover, a triple-negative tumor subtype may be good candidates for breast conservative surgery without axillary surgical staging.

Receiving a diagnosis of a potential fetal anomaly causes severe stress to a pregnant woman. Little is known about the coping strategies used by these women, especially in Egypt. This study explored the coping strategies used by women following unexpected findings in routine antenatal ultrasound scan in Alexandria, Egypt. A mixed method (convergent parallel) quantitative and qualitative approach was used to target pregnant women at 20-32 weeks of gestation. The quantitative study included 93 women, whereas the qualitative one included a purposively chosen subsample of 30 women representing diverse diagnoses. A 10-item questionnaire was used in the quantitative part to assess active, avoidant, and negative coping strategies. In the qualitative part, coping was assessed by analyzing the transcripts of women's experiences. Although women used equal numbers of avoidant and active strategies (3.34±0.56 vs. 3.30±0.73, Z=0.273, P=0.78), the reported effectiveness of active strategies ranked higher than that of the avoidant ones (χ=54.64, P<0.001). Women with an education level up to high school or higher perceived high effectiveness of active and/or avoidant strategies compared with women with less education (χ=4.087, P<0.05). Women concurrently used more than one coping strategy. The effectiveness of active strategies was higher than that of the avoidant ones. The educational level was the only factor associated with perceived high effectiveness of active and/or avoidant strategies. Helping future mothers acquire active coping skills through counseling sessions and support groups are recommended.

Introduction One of the proposed psychobiological pathways of craving attributes the desire for drinking in the context of tension, discomfort or unpleasant emotions, to “negative” (or “relief”) craving. The aim of this study was to replicate a previously reported association of the PDYN rs2281285 variant with negative craving using a different phenotyping approach. Methods The TaqMan® Genotyping Assay was used to genotype the rs2281285 variant in 417 German alcohol-dependent subjects. The presence of negative/relief craving was assessed by asking if participants ever ingested alcohol to avoid unwanted emotional or somatic discomfort. Results The minor allele of rs2281285 was associated with an increased risk of drinking to avoid/escape unwanted emotional or somatic events (OR = 2.29, 95% CI = 1.08–4.85, p = 0.0298). Discussion Despite the use of a different phenotyping approach to the measurement of negative craving, our results confirm the association between negative craving and PDYN rs2281285. Genetic markers of negative craving may help to identify subgroups of alcohol-dependent individuals vulnerable to relapse in the context of negative emotions or somatic discomfort, leading to the development of specifically tailored treatment strategies.

This study examined how older adults cope with negative life events in health, interpersonal, and financial/work domains and whether common stress and coping processes hold across these three domains. On three occasions, older adults identified the most severe negative event they faced in the last year and described how they appraised and coped with that event, their ambient chronic stressors, and event and functioning outcomes. The stress and coping process was largely consistent across the three life domains. Individuals who appraised events as challenging and relied more on approach coping were more likely to report some benefit from those events. Individuals who experienced more chronic stressors and favored avoidance coping were more likely to be depressed and to have late-life drinking problems. Chronic stressors, as well as approach and avoidance coping, were predictably associated with overall outcomes in all three event domains. These findings provide a basis for preventive interventions that may help older adults’ address the most prevalent stressors of aging more effectively. PMID:16454482

Although depressive symptoms during pregnancy have been related to negative maternal and child health outcomes such as preterm birth, low birth weight infants, postpartum depression, and maladaptive mother-infant interactions, studies on the impact of neighborhood environment on depressive symptoms in pregnant women are limited. Pregnant women residing in disadvantaged neighborhoods reported higher levels of depressive symptoms and lower levels of social support. No researchers have examined the relationship between neighborhood environment and avoidance coping in pregnant women. Guided by the Ecological model and Lazarus and Folkman's transactional model of stress and coping, we examined whether social support and avoidance coping mediated associations between the neighborhood environment and depressive symptoms in pregnant African-American women. Pregnant African-American women (n = 95) from a medical center in Chicago completed the instruments twice during pregnancy between 15 and 25 weeks and between 25 and 37 weeks. The self-administered instruments measured perceived neighborhood environment, social support, avoidance coping, and depressive symptoms using items from existing scales. Objective measures of the neighborhood environment were derived using geographic information systems. Perceived neighborhood environment, social support, avoidance coping, and depressive symptoms were correlated significantly in the expected directions. Objective physical disorder and crime were negatively related to social support. Social support at time 1 (20 ± 2.6 weeks) mediated associations between the perceived neighborhood environment at time 1 and depressive symptoms at time 2 (29 ± 2.7 weeks). An increase in avoidance coping between times 1 and 2 also mediated the effects of perceived neighborhood environment at time 1 on depressive symptoms at time 2. Pregnant African-American women's negative perceptions of their neighborhoods in the second trimester were related to higher levels of depressive symptoms in the third trimester. If these results are replicable in prospective studies with larger sample sizes, intervention strategies could be implemented at the individual level to support pregnant women in their ability to cope with adverse neighborhood conditions and ultimately improve their mental health.

2017-02-01

This study focuses on whether risk avoidance in decision making depends on negative affect or it is specific to anxious individuals. The Balloon Analogue Risk Task was used to obtain an objective measure in a risk situation with anxious, depressive, and control individuals. The role of attentional networks was also studied using the Attentional Network Test-Interaction (ANT-I) task with neutral stimuli. A significant difference was observed between anxious and depressive individuals in assumed risk in decision making. We found no differences between anxious and normal individuals in the alert, orientation, and congruency effects obtained in the ANT-I task. The results showed that there was no significant relationship between the risk avoidance and the indexes of alertness, orienting, and control. Future research shall determine whether emotionally relevant stimulation leads to attentional control deficit or whether differences between anxious and no anxious individuals are due to the type of strategy followed in choice tasks.

[Association between approach-avoidance commitment to romantic relationships, emotional experiences in romantic relationships, and personal mental health].

The present study examined the association between approach-avoidance commitment, emotional experiences in romantic relationships, and mental health. It was hypothesized that the association between avoidance commitment and emotional experiences was moderated by approach commitment. Two hundred and three undergraduates who were involved in romantic relationships participated in a questionnaire survey. Results revealed that approach commitment was associated with greater positive emotion and less negative emotion, and these emotional experiences were associated with higher mental health. On the other hand, the association between avoidance commitment and emotional experiences was moderated by approach commitment. That is, only when approach commitment was weak, avoidance commitment was associated with fewer positive emotions and greater negative emotions, and that these emotional experiences were associated with lower mental health. These results reveal that approach-avoidance commitment was associated with mental health via emotional experiences in romantic relationships, and verified Johnson's (1999) and Levinger's (1999) theoretical argument.

The influence of periodic increases of human activity on crepuscular and nocturnal mammals: Testing the weekend effect.

PubMed

Nix, Joshua H; Howell, Ryan G; Hall, Lucas K; McMillan, Brock R

Human recreation can negatively affect wildlife, particularly on weekends when human activity is highest (i.e., the weekend effect). Much of what we understand about the weekend effect is based on research conducted on diurnal species, which have greater temporal overlap with humans. Because nocturnal species generally avoid times when humans are active, they are likely less affected by anthropogenic activity on weekends. Our objective was to test the weekend effect in relation to the degree of nocturnality of mammals in a recreational area. We predicted that as nocturnality increased, the effect of human activity would decrease. To address our objective, we placed 50 remote cameras along the Diamond Fork River in Utah from January to June 2015. We found that three out of the four focal species supported our predictions. Mule deer (crepuscular) reduced activity throughout our entire study area during weekends and avoided campgrounds. Beavers and mountain lions (both nocturnal) did not negatively respond to increased human activity. Raccoons (nocturnal) reduced activity during weekends, but only within campground areas. Our findings indicate that as the temporal overlap increases between wildlife and humans, so does the influence that humans have on wildlife. Copyright © 2017 Elsevier B.V. All rights reserved.

Comparing Angular and Curved Shapes in Terms of Implicit Associations and Approach/Avoidance Responses.

PubMed

Palumbo, Letizia; Ruta, Nicole; Bertamini, Marco

2015-01-01

Most people prefer smoothly curved shapes over more angular shapes. We investigated the origin of this effect using abstract shapes and implicit measures of semantic association and preference. In Experiment 1 we used a multidimensional Implicit Association Test (IAT) to verify the strength of the association of curved and angular polygons with danger (safe vs. danger words), valence (positive vs. negative words) and gender (female vs. male names). Results showed that curved polygons were associated with safe and positive concepts and with female names, whereas angular polygons were associated with danger and negative concepts and with male names. Experiment 2 used a different implicit measure, which avoided any need to categorise the stimuli. Using a revised version of the Stimulus Response Compatibility (SRC) task we tested with a stick figure (i.e., the manikin) approach and avoidance reactions to curved and angular polygons. We found that RTs for approaching vs. avoiding angular polygons did not differ, even in the condition where the angles were more pronounced. By contrast participants were faster and more accurate when moving the manikin towards curved shapes. Experiment 2 suggests that preference for curvature cannot derive entirely from an association of angles with threat. We conclude that smoothly curved contours make these abstract shapes more pleasant. Further studies are needed to clarify the nature of such a preference.

Research on the implication of experiential avoidance in the aetiology and maintenance of diverse forms of psychopathology has grown considerably over the last 10 years. However, the potential contribution of experiential avoidance to cancer-related distress has received limited attention. Accordingly, the objective of this study was to examine the association between experiential avoidance, symptoms of anxiety and depression, and quality of life (QoL) during the course of a psychological group intervention for women with breast cancer. Fifty-four women with breast cancer participated in a psychological group intervention designed to reduce distress and improve QoL. Participants completed measures of experiential avoidance, anxiety and depressive symptoms, and QoL upon the first and last sessions. A path analysis revealed that, after controlling for baseline measures, smaller reductions in experiential avoidance during the course of the intervention predicted smaller reductions in anxiety and depressive symptoms. Also, experiential avoidance had a negative indirect effect on QoL via depressive symptoms. Experiential avoidance may perpetuate the emotional problems commonly found in women with breast cancer and attenuate improvements associated with participation in psychological interventions. Implications for clinical practice in psycho-oncology are discussed. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

The objective of this study was to describe the time required to obtain a negative chlamydia test in pregnant and nonpregnant women following treatment to inform test-of-cure collection and recommend an abstinence period to avoid reinfection. Seventy-two women with Chlamydia trachomatis infection, 36 pregnant and 36 nonpregnant, were enrolled in a prospective cohort study. Women were excluded less than 18 years of age, if they had been treated for chlamydia, reported an allergy to macrolide antibiotics, or if they had Myasthenia Gravis. Women were treated for chlamydia with single-dose therapy and submitted weekly vaginal chlamydia nucleic acid amplification tests (NAATs). Once NAATwere negative, the participants completed the study. Forty-seven women completed the study per protocol. The primary outcome was to determine the time to a negative chlamydia NAAT following treatment, with secondary outcomes of determining the appropriate time to collect a test-of-cure following chlamydia treatment and to recommend an appropriate abstinence period following treatment to avoid reinfection. Results showed that the time to a negative chlamydia NAAT was significantly different between groups (log-rank p = 0.0013). The median number of days to obtain a negative chlamydia NAAT was 8 days (IQR 7–14) in pregnant and 7 days (IQR 6–10) in nonpregnant women (WRST p = 0.04). All participants had a negative chlamydia NAAT by day 29 post-treatment. Following single-dose treatment for chlamydia, both pregnant and nonpregnant women should test negative with NAAT by 30 days post-treatment. Clinicians should collect a test-of-cure in pregnant women no earlier than 1 month. To avoid reinfection, women should avoid condomless intercourse for at least 1 month. PMID:27864473

Effective dynamical coupling of hydrodynamics and transport for heavy-ion collisions

NASA Astrophysics Data System (ADS)

Oliinychenko, Dmytro; Petersen, Hannah

2017-04-01

Present hydrodynamics-based simulations of heavy-ion collisions neglect the feedback from the frozen-out particles flying back into the hydrodynamical region. This causes an artefact called “negative Cooper-Frye contributions”, which is negligible for high collision energies, but becomes significant for lower RHIC BES energies and for event-by-event simulations. To avoid negative Cooper-Frye contributions, while still preserving hydrodynamical behavior, we propose a pure hadronic transport approach with forced thermalization in the regions of high energy density. It is demonstrated that this approach exhibits enhancement of strangeness and mean transverse momenta compared to conventional transport - an effect typical for hydrodynamical approaches.

An experimental investigation into the effects of traffic noise on distributions of birds: avoiding the phantom road

McClure, Christopher J. W.; Ware, Heidi E.; Carlisle, Jay; Kaltenecker, Gregory; Barber, Jesse R.

2013-01-01

Many authors have suggested that the negative effects of roads on animals are largely owing to traffic noise. Although suggestive, most past studies of the effects of road noise on wildlife were conducted in the presence of the other confounding effects of roads, such as visual disturbance, collisions and chemical pollution among others. We present, to our knowledge, the first study to experimentally apply traffic noise to a roadless area at a landscape scale—thus avoiding the other confounding aspects of roads present in past studies. We replicated the sound of a roadway at intervals—alternating 4 days of noise on with 4 days off—during the autumn migratory period using a 0.5 km array of speakers within an established stopover site in southern Idaho. We conducted daily bird surveys along our ‘Phantom Road’ and in a nearby control site. We document over a one-quarter decline in bird abundance and almost complete avoidance by some species between noise-on and noise-off periods along the phantom road and no such effects at control sites—suggesting that traffic noise is a major driver of effects of roads on populations of animals.

2018-01-01

Attachment in adult romantic relationships has long been linked to conflict styles. Psychophysiological measures have provided additional insight into this association by accessing less conscious and controlled responses to conflict. The aim of this study was to explore the relationship between attachment anxiety, attachment avoidance, and the interaction between attachment styles on skin conductance responses during conflict and recovery from conflict. Using dyadic analysis of 50 heterosexual couples, we found evidence of a systemic effect of attachment, where psychophysiological arousal increased when one partner had higher levels of attachment anxiety and the other partner had higher levels of attachment avoidance. Attachment avoidance was also negatively associated with increased levels of arousal. Relationship and clinical implications of these findings are discussed. © 2017 American Association for Marriage and Family Therapy.

Examining attachment to God and health risk-taking behaviors in college students.

Horton, Karissa D; Ellison, Christopher G; Loukas, Alexandra; Downey, Darcy L; Barrett, Jennifer B

2012-06-01

Drawing on insights from attachment theory, this study examined whether three types of attachment to God--secure, avoidant, and anxious--were associated with health-risk behaviors, over and above the effects of religious attendance, peer support, and demographic covariates, in a sample of 328 undergraduate college students. Contrary to prior theory, secure attachment to God is not inversely associated with recent alcohol or marijuana use, or substance use prior to last sexual intercourse. Instead, avoidant and anxious attachment to God are associated with higher levels of drinking; anxious attachment to God is associated with marijuana use; and avoidant attachment to God is associated with substance use prior to last sexual intercourse. These patterns are gender-specific; problematic attachment to God is linked with negative outcomes solely among men.

2014-10-01

This study investigated how sacrificing for approach versus avoidance goals shapes the giver's and the recipient's emotions and relationship quality. A sample of 80 dating couples participated in a three-part study in which they discussed sacrifice in the laboratory (Part 1), reported on their daily sacrifices for 14 days (Part 2), and completed a follow-up survey 3 months later (Part 3). When partners discussed a sacrifice they had made for approach goals, they experienced greater relationship quality, whereas when they discussed a sacrifice they had made for avoidance goals, they experienced poorer relationship quality. These effects were replicated with outside observer reports. On days when partners sacrificed for approach goals, both partners experienced increased relationship quality, but on days when people sacrificed for avoidance goals, the giver experienced decreased relationship quality. These effects were mediated by positive and negative emotions, respectively. Approach sacrifice goals predicted increases in relationship quality and avoidance sacrifice goals predicted decreases in relationship quality, as reported by both partners 3 months later. Sacrifice per se does not help or harm relationships, but the goals that people pursue when they give up their own interests can critically shape the quality of intimate bonds. © 2013 Wiley Periodicals, Inc.

Negative reactions to monitoring: Do they undermine the ability of monitoring to protect adolescents?

PubMed

Laird, Robert D; Zeringue, Megan M; Lambert, Emily S

2018-02-01

This study focused on adolescents' negative reactions to parental monitoring to determine whether parents should avoid excessive monitoring because adolescents find monitoring behaviors to be over-controlling and privacy invasive. Adolescents (n = 242, M age = 15.4 years; 51% female) reported monitoring, negative reactions, warmth, antisocial behavior, depressive symptoms, and disclosure. Adolescents additionally reported antisocial behavior, depressive symptoms, and disclosure one to two years later. In cross-sectional analyses, less monitoring but more negative reactions were linked with less disclosure, suggesting that negative reactions can undermine parents' ability to obtain information. Although monitoring behaviors were not related to depressive symptoms, more negative reactions were linked with more depressive symptoms, suggesting that negative reactions also may increase depressive symptoms as a side effect of monitoring behavior. Negative reactions were not linked to antisocial behavior. There were no longitudinal links between negative reactions and changes in disclosure, antisocial behavior, or depressive symptoms.

How to mitigate impacts of wind farms on bats? A review of potential conservation measures in the European context

DOE Office of Scientific and Technical Information (OSTI.GOV)

Peste, Filipa, E-mail: filipapeste@gmail.com; Department of Biology, University of Aveiro; Paula, Anabela

Wind energy is growing worldwide as a source of power generation. Bat assemblages may be negatively affected by wind farms due to the fatality of a significant number of individuals after colliding with the moving turbines or experiencing barotrauma. The implementation of wind farms should follow standard procedures to prevent such negative impacts: avoid, reduce and offset, in what is known as the mitigation hierarchy. According to this approach avoiding impacts is the priority, followed by the minimisation of the identified impacts, and finally, when residual negative impacts still remain, those must be offset or at least compensated. This papermore » presents a review on conservation measures for bats and presents some guidelines within the compensation scenario, focusing on negative impacts that remain after avoidance and minimisation measures. The conservation strategies presented aim at the improvement of the ecological conditions for the bat assemblage as a whole. While developed under the European context, the proposed measures are potentially applicable elsewhere, taking into consideration the specificity of each region in terms of bat assemblages present, landscape features and policy context regarding nature and biodiversity conservation and management. An analysis of potential opportunities and constraints arising from the implementation of offset/compensation programmes and gaps in the current knowledge is also considered. - Highlights: • Wind energy impacts bat populations in ways not yet fully understood. • As the use of windfarms is growing worldwide greater impacts on bat populations are also expected. • Mitigation hierarchy provides a way to reduce impacts from new wind farm facilities. • Compensation measures may be used to reduce the residual effects on bat populations. • Identify bats ecological needs and compensate according to the existing surroundings.« less

The experience of touch is critical for early communication and social interaction; infants who show aversion to touch may be at risk for atypical development and behavior problems. The current study aimed to clarify predictive associations between infant responses to tactile stimuli and toddler autism spectrum, internalizing, and externalizing behaviors. This study measured 9-month-old infants' (N = 561; 58% male) avoidance and negative affect during a novel tactile task in which parents painted infants' hands and feet and pressed them to paper to make a picture. Parent reports on the Pervasive Developmental Problems (PDP), Internalizing, and Externalizing scales of the Child Behavior Checklist were used to measure toddler behaviors at 18 months. Infant observed avoidance and negative affect were significantly correlated; however, avoidance predicted subsequent PDP scores only, independent of negative affect, which did not predict any toddler behaviors. Findings suggest that incorporating measures of responses to touch in the study of early social interaction may provide an important and discriminating construct for identifying children at greater risk for social impairments related to autism spectrum behaviors. © 2015 Michigan Association for Infant Mental Health.

An increasing problem in publication ethics: Publication bias and editors' role in avoiding it.

PubMed

Ekmekci, Perihan Elif

2017-06-01

Publication bias is defined as "the tendency on the parts of investigators, reviewers, and editors to submit or accept manuscripts for publication based on the direction or the strength of the study findings."Publication bias distorts the accumulated data in the literature, causes the over estimation of potential benefits of intervention and mantles the risks and adverse effects, and creates a barrier to assessing the clinical utility of drugs as well as evaluating the long-term safety of medical interventions. The World Medical Association, the International Committee of Medical Journals, and the Committee on Publication Ethics have conferred responsibilities and ethical obligations to editors concerning the avoidance of publication bias. Despite the explicit statements in these international documents, the editors' role in and ability to avoid publication bias is still being discussed. Unquestionably, all parties involved in clinical research have the ultimate responsibility to sustain the research integrity and validity of accumulated general knowledge. Cooperation and commitment is required at every step of a clinical trial. However, this holistic approach does not exclude effective measures to be taken at the editors' level. The editors of major medical journals concluded that one precaution that editors can take is to mandate registration of all clinical trials in a public repository as a precondition to submitting manuscripts to journals. Raising awareness regarding the value of publishing negative data for the scientific community and human health, and increasing the number of journals that are dedicated to publishing negative results or that set aside a section in their pages to do so, are positive steps editors can take to avoid publication bias.

Using Thermal Radiation in Detection of Negative Obstacles

A method of automated detection of negative obstacles (potholes, ditches, and the like) ahead of ground vehicles at night involves processing of imagery from thermal-infrared cameras aimed at the terrain ahead of the vehicles. The method is being developed as part of an overall obstacle-avoidance scheme for autonomous and semi-autonomous offroad robotic vehicles. The method could also be applied to help human drivers of cars and trucks avoid negative obstacles -- a development that may entail only modest additional cost inasmuch as some commercially available passenger cars are already equipped with infrared cameras as aids for nighttime operation.

Why do people expose themselves to certain emotional stimuli and avoid others? We propose that what people want to feel is linked to attitudes toward emotions. In 3 studies, we show that individuals with more (vs. less) negative attitudes toward an emotion were more (vs. less) likely to avoid stimuli that induce that emotion. People who evaluated disgust (or joy) less favorably than others were less likely to expose themselves to disgusting (or joyful) pictures (Study 1). These links were emotion-specific and could not be explained by differences in state or trait emotion (Study 2) or in emotional reactivity (Study 3). We were further able to show that the choice of emotion-inducing stimuli affected emotional experience in a congruent manner. People with more (vs. less) negative attitudes toward disgust (or sadness) were more likely to avoid disgusting (or sad) stimuli, resulting in more intense experiences of disgust (or sadness; Study 2). Finally, people with more negative attitudes toward disgust chose to avoid more disgusting stimuli, whether attitudes were assessed explicitly or implicitly (Study 3). These findings suggest that people avoid stimuli that induce emotions that they evaluate less favorably, even when such evaluations are not consciously accessible.

Disturbances in emotional functioning may contribute to psychological and physical symptoms in patients with fibromyalgia. This study examined emotions and emotion-regulation strategies in women with fibromyalgia and in controls, and how these variables relate to symptoms of fibromyalgia. We compared 403 women with fibromyalgia to 196 control women using self-report questionnaires. Negative emotions and the use of emotional-avoidance strategies were elevated, and positive emotions were reduced, in fibromyalgia patients; the alexithymia scale "difficulty identifying feelings" showed a large deviation from normal. Emotional-approach measures were not deviant. In the fibromyalgia sample, emotional-avoidance strategies were highly correlated with more mental distress and were modestly correlated with more pain and fatigue, while emotional-approach strategies were only minimally related to better functioning. We tested two interaction models. The intense experiencing of emotions was related to more pain only in patients who lack the ability to process or describe emotions. Although fibromyalgia patients showed deficits in the experiencing of positive affect, positive affect did not buffer the association between pain and negative affect. This study demonstrates increased negative emotions and decreased positive emotions, as well as increased emotional-avoidance strategies, in women with fibromyalgia. Research should test whether interventions that reduce emotional avoidance lead to health improvements in women with fibromyalgia.

The effects of anxiety upon attention allocation to affective stimuli.

Pictures of emotionally aversive, neutral, and pleasant scenes were presented for 500 ms, followed by a probe presented in the same location (valid trials) or an alternate location (invalid trials) as the picture. Response-times to the probes were recorded in low (N=20) and high (N=27) trait anxious participants. Results revealed an overall negative cue validity effect of shorter reaction times (RTs) on invalid than valid trials, suggestive of an inhibition of return effect. Moreover, high trait anxious females showed a reduced negative cue validity effect for aversive pictures in comparison with neutral and pleasant pictures, suggestive of selective interference by the unpleasant material. By contrast, low trait anxious females showed an enhanced negative cue validity effect for aversive pictures relative to neutral and pleasant pictures, suggestive of attentional avoidance of the aversive content. The emotional content of picture cues did not significantly affect RTs in males, regardless of anxiety status. The results suggest that biased attention processes for aversive stimuli may contribute to the greater female propensity for anxiety disorders.

Individual differences in cognitive processes and coping behaviors play a role in the development and maintenance of posttraumatic stress disorder (PTSD). Given the large numbers of combat-exposed service members returning from the Operation Enduring Freedom (OEF), Operation Iraqi Freedom (OIF), and Operation New Dawn (OND) conflicts, exploring individual differences in cognitive-affective processes is important for informing our understanding of PTSD etiology and early intervention in military samples. The present study examined the unique main and interactive effects of negative posttrauma cognitions (i.e., negative beliefs about self [NS], the world [NW], and self-blame [SB]) and coping strategies (i.e., positive behavioral, positive cognitive, avoidant coping, and social and emotional coping) on PTSD diagnosis within 155 ( M age = 30.7, SD = 4.48) OEF/OIF/OND combat trauma-exposed veterans recruited from an ongoing study examining the effects of combat trauma and stress reactivity. In the final, stepwise logistic regression analysis, avoidant coping, but no other coping strategy, was significantly positively related to PTSD diagnosis in the initial step. Higher levels of NS, but not NW, were significantly associated with having a PTSD diagnosis, while SB was associated with decreased likelihood of PTSD, above and beyond coping strategies. A significant interaction effect was found between NS and positive cognitive coping, such that greater positive cognitive coping weakened the relationship between NS and PTSD. Examining and addressing coping behaviors and negative thoughts of self jointly may benefit assessment and intervention approaches in a combat-trauma population.

Cocaine has been shown to have initial positive (euphoric) and delayed negative (anxiogenic) effects in both humans and animals. Cocaine-paired cues are consequently imbued with mixed positive and negative associations. The current study examines the relative roles of these dual associations in the enhanced drug-seeking observed upon presentation of cocaine-paired cues. Rats ran a straight alley once/day for a single i.v. injection of cocaine (1.0 mg/kg/inj) in the presence of a distinctive olfactory cue (scented cotton swabs placed under the apparatus). An alternate scent was presented in a separate cage 2-h prior to runway testing. After 15 trials/days, the scents and cocaine reinforcer were removed and a series of extinction trials (lasting for 1 or 3 weeks) was initiated. Immediately following extinction, runway responding was tested during a single trial in the presence of the cocaine-paired or non-paired cue. As previously reported, while subjects initiated responding faster over trials (reduced latencies to leave the start box), they exhibited a progressive increase in approach-avoidance conflict behavior ("retreats") regarding goal-box entry, reflecting cocaine's dual positive+negative effects. Once established, retreat behaviors persisted over the course of 1 or 3 weeks days of extinction. However, both run times and retreats decreased in response to presentation of the cocaine-paired but not the non-paired scent. These data suggest that, after reinforcer removal, cue-induced cocaine-seeking stems in part from a reduction in approach-avoidance conflict; i.e., a greater weakening of the negative relative to the positive associations that animals form with cocaine-paired stimuli.

Hikikomori, a severe form of social withdrawal syndrome, is a growing social issue in Japan and internationally. The pathophysiology of hikikomori has not yet been elucidated and an effective treatment remains to be established. Recently, we revealed that avoidant personality disorder is the most common comorbidity of hikikomori. Thus, we have postulated that avoidant personality is the personality underpinning hikikomori. First, we herein show relationships between avoidant personality traits, blood biomarkers, hikikomori-related psychological features, and behavioural characteristics assessed by a trust game in non-hikikomori volunteers. Avoidant personality traits were negatively associated with high-density lipoprotein cholesterol (HDL-C) and uric acid (UA) in men, and positively associated with fibrin degeneration products (FDP) and high sensitivity C-reactive protein (hsCRP) in women. Next, we recruited actual individuals with hikikomori, and compared avoidant personality traits, blood biomarkers, and psychological features between individuals with hikikomori and age-matched healthy controls. Individuals with hikikomori had higher avoidant personality scores in both sexes, and showed lower serum UA levels in men and lower HDL-C levels in women compared with healthy controls. This is the first report showing possible blood biomarkers for hikikomori, and opens the door to clarify the underlying biological pathophysiology of hikikomori.

Task avoidance is a significant predictor of literacy skills. However, it remains unclear whether the relation between the two is reciprocal and whether it is affected by the type of literacy outcome, who is rating children's task avoidance, and the children's gender. The purpose of this longitudinal study was to examine the cross-lagged relations between teacher and parent ratings of children's task avoidance and different literacy skills. One hundred and seventy-two Greek children (91 girls, 81 boys) were followed from Grade 1 to Grade 3. Children were assessed on reading accuracy, reading fluency, and spelling to dictation. Parents and teachers rated the children's task-avoidant behaviour. Results of structural equation modelling showed that the cross-lagged relations varied as a function of the literacy outcome, who rated the children's task avoidance, and children's gender. Earlier reading and spelling performance predicted subsequent parent-rated task avoidance, but parent-rated task avoidance did not predict subsequent reading and spelling performance (with the exception of spelling in Grade 3). Teacher-rated task avoidance and reading fluency/spelling had a reciprocal relationship over time. In addition, the effects of teacher-rated task avoidance on future spelling were significantly stronger in boys than in girls. This suggests that poor reading and spelling performance can lead to subsequent task avoidance in both classroom and home situations. The fact that task avoidance permeates across different learning environments is alarming and calls for joint action from both parents and teachers to mitigate its negative impact on learning. © 2017 The British Psychological Society.

The purpose of the present study was to investigate the effects of social stress and stress-induced cortisol on the preconscious selective attention to social threat. Twenty healthy participants were administered a masked emotional Stroop task (comparing color-naming latencies for angry, neutral and happy faces) in conditions of rest and social stress. Stress was induced by means of the Trier social stress test. Based on the stress-induced increase in cortisol levels, participants were allocated post hoc (median-split) to a high and low responders group. In contrast to low responders, high responders showed a negative or avoidant attentional bias to threat (i.e. shorter latencies for angry than neutral faces) in the rest condition. Most importantly, although low responders became avoidant, the high responders became vigilant to the angry faces after stress induction. There were no such effects for happy faces. Our findings are in line with previous studies in both animals and humans, that associate high glucocorticoid stress-responsiveness with diminished avoidance and prolonged freezing reactions during stress.

This research examined whether military service members' deployment-related trauma exposure, posttraumatic stress disorder (PTSD) symptoms, and experiential avoidance are associated with their observed levels of positive social engagement, social withdrawal, reactivity-coercion, and distress avoidance during postdeployment family interaction. Self reports of deployment related trauma, postdeployment PTSD symptoms, and experiential avoidance were collected from 184 men who were deployed to the Middle East conflicts, were partnered, and had a child between 4 and 13 years of age. Video samples of parent-child and partner problem solving and conversations about deployment issues were collected, and were rated by trained observers to assess service members' positive engagement, social withdrawal, reactivity-coercion, and distress avoidance, as well as spouse and child negative affect and behavior. Service members' experiential avoidance was reliably associated with less observed positive engagement and more observed withdrawal and distress avoidance after controlling for spouse and child negative affect and behavior during ongoing interaction. Service members' experiential avoidance also diminished significant associations between service members' PTSD symptoms and their observed behavior. The results are discussed in terms of how service members' psychological acceptance promotes family resilience and adaption to the multiple contextual challenges and role transitions associated with military deployment. Implications for parenting and marital interventions are described. (c) 2016 APA, all rights reserved).

Cognitive avoidance of intrusive memories: recall vantage perspective and associations with depression.

Williams, Alishia D; Moulds, Michelle L

2007-06-01

Although recent research demonstrates that intrusive memories represent an overlapping cognitive feature of depression and post-traumatic stress disorder (PTSD), there is still a general paucity of research investigating the prevalence and maintenance of intrusive memories in depression. The current study investigated the association between a range of cognitive avoidant mechanisms that characterize PTSD samples (i.e., suppression, rumination, emotional detachment, and an observer vantage perspective) and intrusive memories of negative autobiographical events in relation to dysphoria. Hypotheses were based on the proposition that employment of these cognitive mechanisms would hinder the emotional processing of the negative event, thus contributing to the maintenance of intrusions. Results supported an association between negative intrusive memories, dysphoria, and avoidant mechanisms. Significant differences were also found between field and observer memories and measures of emotional detachment and rumination. Implications relating to intrusive memory maintenance and treatment approaches are discussed.

Perceived social pressure not to experience negative emotion is linked to selective attention for negative information.

PubMed

Social norms and values may be important predictors of how people engage with and regulate their negative emotional experiences. Previous research has shown that social expectancies (the perceived social pressure not to feel negative emotion (NE)) exacerbate feelings of sadness. In the current research, we examined whether social expectancies may be linked to how people process emotional information. Using a modified classical flanker task involving emotional rather than non-emotional stimuli, we found that, for those who experienced low levels of NE, social expectancies were linked to the selective avoidance of negative emotional information. Those who experienced high levels of NE did not show a selective avoidance of negative emotional information. The findings suggest that, for people who experience many NEs, social expectancies may lead to discrepancies between how they think they ought to feel and the kind of emotional information they pay attention to.

HIV diagnosis presents a critical opportunity to reduce secondary transmission, improve engagement in care, and enhance overall well-being. To develop relevant interventions, research is needed on the psychosocial experiences of newly diagnosed individuals. This study examined avoidant coping, self-efficacy for HIV disclosure decisions, and depression among 92 newly diagnosed men who have sex with men who reported recent sexual risk behavior. It was hypothesized that avoidant coping would mediate the relationship between self-efficacy and depression. Cross-sectional surveys were collected from participants 3 months after HIV diagnosis. To test for mediation, multiple linear regressions were conducted while controlling for HIV disclosure to sexual partners. Self-efficacy for HIV disclosure decisions showed a negative linear relationship to depression symptoms, and 99% of this relationship was mediated by avoidant coping. The index of mediation of self-efficacy on depression indicated a small-to-medium effect. Higher self-efficacy was related to less avoidant coping, and less avoidant coping was related to decreased depression symptoms, all else held constant. These findings highlight the role of avoidant coping in explaining the relationship between self-efficacy for HIV disclosure decisions and depression.

Marital stress has been associated with immune dysregulation, including increased production of interleukin-6 (IL-6). Attachment style, one’s expectations about the availability and responsiveness of others in intimate relationships, appears to influence physiological stress reactivity and thus could influence inflammatory responses to marital conflict. Thirty-five couples were invited for two 24-hour admissions to a hospital research unit. The first visit included a structured social support interaction, while the second visit comprised the discussion of a marital disagreement. A mixed effect within-subject repeated measure model indicated that attachment avoidance significantly influenced IL-6 production during the conflict visit but not during the social support visit. Individuals with higher attachment avoidance had on average an 11% increase in total IL-6 production during the conflict visit as compared to the social support visit, while individuals with lower attachment avoidance had, on average, a 6% decrease in IL-6 production during the conflict visit as compared to the social support visit. Furthermore, greater attachment avoidance was associated with a higher frequency of negative behaviors and a lower frequency of positive behaviors during the marital interaction, providing a mechanism by which attachment avoidance may influence inflammatory responses to marital conflict. In sum, these results suggest that attachment avoidance modulates marital behavior and stress-induced immune dysregulation. PMID:18952163

Avoidance-based human Pavlovian-to-instrumental transfer

PubMed Central

Lewis, Andrea H.; Niznikiewicz, Michael A.; Delamater, Andrew R.; Delgado, Mauricio R.

2013-01-01

The Pavlovian-to-instrumental transfer (PIT) paradigm probes the influence of Pavlovian cues over instrumentally learned behavior. The paradigm has been used extensively to probe basic cognitive and motivational processes in studies of animal learning but, more recently, PIT and its underlying neural basis have been extended to investigations in humans. These initial neuroimaging studies of PIT have focused on the influence of appetitively conditioned stimuli on instrumental responses maintained by positive reinforcement, and highlight the involvement of the striatum. In the current study, we sought to understand the neural correlates of PIT in an aversive Pavlovian learning situation when instrumental responding was maintained through negative reinforcement. Participants exhibited specific PIT, wherein selective increases in instrumental responding to conditioned stimuli occurred when the stimulus signaled a specific aversive outcome whose omission negatively reinforced the instrumental response. Additionally, a general PIT effect was observed such that when a stimulus was associated with a different aversive outcome than was used to negatively reinforce instrumental behavior, the presence of that stimulus caused a non-selective increase in overall instrumental responding. Both specific and general PIT behavioral effects correlated with increased activation in corticostriatal circuitry, particularly in the striatum, a region involved in cognitive and motivational processes. These results suggest that avoidance-based PIT utilizes a similar neural mechanism to that seen with PIT in an appetitive context, which has implications for understanding mechanisms of drug-seeking behavior during addiction and relapse.

2010-12-01

Most studies on coping among persons with severe mental illness have relied on retrospective self-report methods; a limitation of this methodology is susceptibility to recall bias. The purpose of the present investigation was to expand the current understanding of the impact of coping among persons with severe mental illness by examining coping strategies, mood, and social functioning (operationalized as productive time use) using a daily process design. Twenty-seven adults diagnosed with severe mental illness completed baseline clinical interviews and up to 20 days of nightly telephone interviews addressing coping and daily life. A total of 198 coping efforts were reported for 387 days. Mixed-effects regression analyses examined the association between type of daily coping strategy (problem-centered, neutral, or avoidant) and both daily proportion of time participants spent in productive activity and daily negative mood, controlling for demographic and clinical variables. The results indicated that productive time use was significantly lower on days when avoidant strategies were used, in contrast with days when problem-centered strategies and neutral strategies were used. There was no significant main effect of coping on negative mood, although there was a trend in the expected direction. Findings support the hypothesis that the types of coping strategies adults with severe mental illness use are related to better social functioning on a daily level. Copyright © 2010 Elsevier B.V.

Culture-general and -specific associations of attachment avoidance and anxiety with perceived parental warmth and psychological control among Turk and Belgian adolescents.

2010-10-01

Both the adolescent peer attachment and perceived parenting style literatures emphasize the role of the quality of the parent-child relationship in children's healthy adjustment beyond the family, but few studies have investigated links between adolescents' peer attachment and perceptions of parenting. We investigate relations of adolescents' perceptions of warmth and psychological control from parents with avoidance and anxiety in attachment to close friends in two contrasting cultures. Altogether, 262 Turk and 263 Belgian youth between 14 and 18 years of age participated. Cross-culturally, attachment avoidance was negatively related to maternal warmth, and attachment anxiety positively related to maternal and paternal control and negatively to paternal warmth. Beyond these general relations, attachment avoidance was associated with paternal psychological control in Belgians but not in Turks. The study provides cross-cultural evidence for specific relations between peer attachment and perceived parenting and suggests a culture-specific pathway for the development of attachment avoidance.

2014-01-01

Many study designs and design variants have been developed in the past to either overcome or enhance drug-placebo differences in clinical trials or to identify and characterize placebo responders in experimental studies. They share many commonalities as well as differences that are discussed here: the role of deception and ethical restrictions, habituation effects and the control of the natural course of disease, assay sensitivity testing and effective blinding, acceptability and motivation of patients and volunteers, and the development of individualized medicine. These are fostered by two opposite strategies: utilizing the beneficial aspects of the placebo response-and avoiding its negative counterpart, the nocebo effect-in medical routine for the benefit of patients, and minimizing-by controlling-the negative aspects of the placebo effect during drug development.

HIV/STD Stigmatization Fears as Health Seeking Barriers in China

Internationally, stigma prohibits effective HIV/STD identification, prevention, and care. Interviews with 106 persons in an urban center in Eastern China, some know to have engaged in stigmatized risk acts (sex workers, STD clinic patients) and some vulnerable for stigmatization fears to influence health seeking behaviors (market employees, rural-to-urban migrants). Interviews focused on community norms, values, beliefs, and emotional and behavioral reactions to HIV/STD stigmatization related events. Attributions for infection were found to: mark individual's failure to adhere to sexuality norms; define a condition warranting the avoidance of infected persons and dismissal by medical professionals; and promote anticipation of negative emotions (i.e., shame, fear, and embarrassment) and devalued social roles and status. Strategies reported to avoid stigmatization include: avoiding HIV/STD knowledge; avoiding health care professionals, particularly in public settings; and conforming to community norms of shunning those suspected of risky behaviors. Results have direct implications for community marketing campaigns in China. PMID:16374668

More than a hundred hydropower dams have already been built in the Amazon basin and numerous proposals for further dam constructions are under consideration. The accumulated negative environmental effects of existing dams and proposed dams, if constructed, will trigger massive hydrophysical and biotic disturbances that will affect the Amazon basin’s floodplains, estuary and sediment plume. We introduce a Dam Environmental Vulnerability Index to quantify the current and potential impacts of dams in the basin. The scale of foreseeable environmental degradation indicates the need for collective action among nations and states to avoid cumulative, far-reaching impacts. We suggest institutional innovations to assess and avoid the likely impoverishment of Amazon rivers.

A novel profit-allocation strategy for SDN enterprises

2017-01-01

Aiming to solve the problem of profit allocation for supply and demand network (SDN) enterprises that ignores risk factors and generates low satisfaction, a novel profit-allocation model based on cooperative game theory and TOPSIS is proposed. This new model avoids the defect of the single-profit allocation model by introducing risk factors, compromise coefficients and high negotiation points. By measuring the Euclidean distance between the ideal solution vector and the negative ideal solution vector, every node's satisfaction problem for the SDN was resolved, and the mess phenomenon was avoided. Finally, the rationality and effectiveness of the proposed model was verified using a numerical example.

Market turbulence creates financing opportunity.

The flight to high-quality assets resulting from Standard & Poor's downgrade of the U.S. government's credit rating has dropped the yield on U.S. Treasury securities as investors have sought refuge amid uncertain market conditions. Consequently, hospitals can now obtain mortgage insurance from the U.S. government to finance expansions and refinance their debt with GNMA securities at taxable interest rates that are often more favorable than tax-exempt bond fixed rates. Because GNMA certificates can be sold in a forward purchase transaction that locks in a fixed interest rate while avoiding payment of interest until construction funds are disbursed, they can help avoid the effects of negative arbitrage.

Delayed medical care has negative health and economic consequences; interventions have focused on appraising symptoms, with limited success in reducing delay. To identify predictors of care avoidance and reasons for avoiding care. Using the Health Information National Trends Survey (2007), we conducted logistic regressions to identify predictors of avoiding medical visits deemed necessary by the respondents; and, we then conducted similar analyses on reasons given for avoidance behavior. Independent variables included geographic, demographic, socioeconomic, personal health, health behavior, health care system, and cognitive characteristics. Approximately one third of adults avoided doctor visits they had deemed necessary. Although unadjusted associations existed, avoiding needed care was not independently associated with geographic, demographic, and socioeconomic characteristics. Avoidance behavior is characterized by low health self-efficacy, less experience with both quality care and getting help with uncertainty about health, having your feelings attended to by your provider, no usual source of care, negative affect, smoking daily, and fatalistic attitude toward cancer. Reasons elicited for avoidance include preference for self-care or alternative care, dislike or distrust of doctors, fear or dislike of medical treatments, time, and money; respondents also endorsed discomfort with body examinations, fear of having a serious illness, and thoughts of dying. Distinct predictors distinguish each of these reasons. Interventions to reduce patient delay could be improved by addressing the health-related behavioral, belief, experiential, and emotional traits associated with delay. Attention should also be directed toward the interpersonal communications between patients and providers.

Attachment Insecurity and Infidelity in Marriage: Do Studies of Dating Relationships Really Inform Us about Marriage?

Attachment theory provides a useful framework for predicting marital infidelity. However, most research has examined the association between attachment and infidelity in unmarried individuals, and we are aware of no research that has examined the role of partner attachment in predicting infidelity. In contrast to research showing that attachment anxiety is unrelated to infidelity among dating couples, 2 longitudinal studies of 207 newlywed marriages demonstrated that own and partner attachment anxiety interacted to predict marital infidelity, such that spouses were more likely to perpetrate infidelity when either they or their partner was high (vs. low) in attachment anxiety. Further, and also in contrast to research on dating couples, own attachment avoidance was unrelated to infidelity whereas partner attachment avoidance was negatively associated with infidelity indicating that spouses were less likely to perpetrate infidelity when their partner was high (vs. low) in attachment avoidance. These effects emerged controlling for marital satisfaction, sexual frequency, and personality, did not differ across husbands and wives, and did not differ across the two studies, with the exception that the negative association between partner attachment avoidance and own infidelity only emerged in one of the two studies. These findings offer a more complete understanding of the implications of attachment insecurity for marital infidelity and suggest that studies of unmarried individuals may not provide complete insights into the implications of various psychological traits and processes for marriage.

Sullivan, Sheena G.; Tchetgen Tchetgen, Eric J.; Cowling, Benjamin J.

2016-01-01

Influenza viruses undergo frequent antigenic changes. As a result, the viruses circulating change within and between seasons, and the composition of the influenza vaccine is updated annually. Thus, estimation of the vaccine's effectiveness is not constant across seasons. In order to provide annual estimates of the influenza vaccine's effectiveness, health departments have increasingly adopted the “test-negative design,” using enhanced data from routine surveillance systems. In this design, patients presenting to participating general practitioners with influenza-like illness are swabbed for laboratory testing; those testing positive for influenza virus are defined as cases, and those testing negative form the comparison group. Data on patients' vaccination histories and confounder profiles are also collected. Vaccine effectiveness is estimated from the odds ratio comparing the odds of testing positive for influenza among vaccinated patients and unvaccinated patients, adjusting for confounders. The test-negative design is purported to reduce bias associated with confounding by health-care-seeking behavior and misclassification of cases. In this paper, we use directed acyclic graphs to characterize potential biases in studies of influenza vaccine effectiveness using the test-negative design. We show how studies using this design can avoid or minimize bias and where bias may be introduced with particular study design variations. PMID:27587721

Single prolonged stress impairs social and object novelty recognition in rats.

Eagle, Andrew L; Fitzpatrick, Chris J; Perrine, Shane A

2013-11-01

Posttraumatic stress disorder (PTSD) results from exposure to a traumatic event and manifests as re-experiencing, arousal, avoidance, and negative cognition/mood symptoms. Avoidant symptoms, as well as the newly defined negative cognitions/mood, are a serious complication leading to diminished interest in once important or positive activities, such as social interaction; however, the basis of these symptoms remains poorly understood. PTSD patients also exhibit impaired object and social recognition, which may underlie the avoidance and symptoms of negative cognition, such as social estrangement or diminished interest in activities. Previous studies have demonstrated that single prolonged stress (SPS), models PTSD phenotypes, including impairments in learning and memory. Therefore, it was hypothesized that SPS would impair social and object recognition memory. Male Sprague Dawley rats were exposed to SPS then tested in the social choice test (SCT) or novel object recognition test (NOR). These tests measure recognition of novelty over familiarity, a natural preference of rodents. Results show that SPS impaired preference for both social and object novelty. In addition, SPS impairment in social recognition may be caused by impaired behavioral flexibility, or an inability to shift behavior during the SCT. These results demonstrate that traumatic stress can impair social and object recognition memory, which may underlie certain avoidant symptoms or negative cognition in PTSD and be related to impaired behavioral flexibility.

Effects of stress and coping on binge eating in female college students.

PubMed

Sulkowski, Michael L; Dempsey, Jack; Dempsey, Allison G

2011-08-01

Limited research exists on the association between stress, coping, and binge eating. To address this paucity, this study explores these associations in a sample of 147 female college students, an at-risk population for binge eating. We hypothesized that emotional and avoidant coping would be positively associated with stress and binge eating. Conversely, we expected that rational and detached coping would be negatively related to stress and binge eating. Furthermore, we expected these coping styles to mediate the relationship between stress and binge eating. As predicted, emotion-focused and avoidant coping were positively associated with stress and binge eating. Additionally, emotion-focused coping partially mediated the relationship between stress and binge eating. However, no association was found between stress, rational or detached coping, and binge eating. These results are discussed within the context of a negative reinforcement model of binge eating. Lastly, the importance of providing evidence-based treatment for individuals with binge eating symptomology is discussed in light of our findings. Copyright © 2011 Elsevier Ltd. All rights reserved.

The 2 × 2 Standpoints Model of Achievement Goals

PubMed Central

Korn, Rachel M.; Elliot, Andrew J.

2016-01-01

In the present research, we proposed and tested a 2 × 2 standpoints model of achievement goals grounded in the development-demonstration and approach-avoidance distinctions. Three empirical studies are presented. Study 1 provided evidence supporting the structure and psychometric properties of a newly developed measure of the goals of the 2 × 2 standpoints model. Study 2 documented the predictive utility of these goal constructs for intrinsic motivation: development-approach and development-avoidance goals were positive predictors, and demonstration-avoidance goals were a negative predictor of intrinsic motivation. Study 3 documented the predictive utility of these goal constructs for performance attainment: Demonstration-approach goals were a positive predictor and demonstration-avoidance goals were a negative predictor of exam performance. The conceptual and empirical contributions of the present research were discussed within the broader context of existing achievement goal theory and research. PMID:27242641

INFLUENCE OF PARENT-ADOLESCENT CONFLICT FREQUENCY ON ADOLESCENT FAMILY SATISFACTION AND SELF-SATISFACTION IN CHINA: CONFLICT COPING TACTICS AS MODERATORS.

Existing studies have found that parent-adolescent conflict frequency and conflict coping tactics influence adolescent family satisfaction and self-satisfaction under the background of Western culture. However, due to differences between Eastern and Western cultures, it is unknown whether previous results of the Western population can be extended to Chinese adolescents. The present study investigated grade differences in parent-adolescent conflict frequency and conflict coping tactics and examined the moderating effects of conflict coping tactics on the relationships between conflict frequency and adolescent family satisfaction and between conflict frequency and adolescent self-satisfaction. Chinese adolescents in Grades 7, 8, 10, and 11 (N = 524) completed measures on conflict frequency, conflict coping tactics, family satisfaction, and self-satisfaction. An analysis of variance (ANOVA) and structural equation model analyses found, first, that conflict frequency decreased with grade level. For coping tactics, conciliation, avoidance, and assertion behaviors increased with grade level. Second, conflict frequency was negatively related to family satisfaction regardless of conciliation and avoidance tactics. By contrast, conflict frequency was negatively related to self-satisfaction when high conciliation and high avoidance behaviors were practiced. In addition, at low conflict frequency conciliation was positively associated with self-satisfaction and was not significant at high conflict frequency.

Positive and negative tropic curvature induced by microbeam irradiation of protonemal tip cells of the moss Ceratodon purpureus.

2004-01-01

The photoreceptor phytochrome mediates tropic responses in protonemata of the moss Ceratodon purpureus. Under standard conditions the tip cells grow towards unilateral red light, or perpendicular to the electrical vector of polarized light. In this study the response of tip cells to partial irradiation of the apical region was analysed using a microbeam apparatus. The fluence response curve gave an unexpected pattern: whereas a 15-min microbeam with light intensities around 3 micro mol m (-2) s (-1) induced a growth curvature towards the irradiated side, higher light intensities around 100 micro mol m (-2) s (-1) caused a negative response, the cells grew away from the irradiated side. This avoidance response is explained by two effects: the light intensity is high enough to induce photoconversion into the active Pfr form of phytochrome, not only on the irradiated but also on the non-irradiated side by stray light. At the same time, the strong light on the irradiated side acts antagonistically to Pfr. As a result of this inhibition, the growth direction is moved to the light-avoiding side. Such a Pfr-independent mechanism might be important for the phototropic response to distinguish between the light-directed and light-avoiding side under unilateral light.

RESILIENCE THEORY AND ITS IMPLICATIONS FOR CHINESE ADOLESCENTS.

PubMed

Wang, Jin-Liang; Zhang, Da-Jun; Zimmerman, Marc A

2015-10-01

Over the past 20 years, resilience theory has attracted great attention from both researchers and mental health practitioners. Resilience is defined as a process of overcoming the negative effects of risk exposure, coping successfully with traumatic experiences, or avoiding the negative trajectories associated with risks. Three basic models of resilience have been proposed to account for the mechanism whereby promotive factors operate to alter the trajectory from risk exposure to negative consequences: compensatory model, protective model, and inoculation model. Assets and resources are two types of promotive factors found to be effective in decreasing internalizing and externalizing problems. Considering the protective or compensatory role of assets and resources in helping youth be resilient against negative effects of adversity, resilience could be applied to Chinese migrant and left-behind children who are at risk for internalizing (e.g., depression, anxiety) and externalizing problems (e.g., delinquent behaviors, cigarette and alcohol use). Additionally, psychological suzhi-based interventions, a mental health construct for individuals that focuses on a strengths-based approach, can be integrated with resilience-based approach to develop more balanced programs for positive youth development.

Reported emergency department avoidance, use, and experiences of transgender persons in Ontario, Canada: results from a respondent-driven sampling survey.

Transgender, transsexual, or transitioned (trans) people have reported avoiding medical care because of negative experiences or fear of such experiences. The extent of trans-specific negative emergency department (ED) experiences, and of ED avoidance, has not been documented. The Trans PULSE Project conducted a survey of trans people in Ontario, Canada (n=433) in 2009 to 2010, using respondent-driven sampling, a tracked network-based method for studying hidden populations. Weighted frequencies and bootstrapped 95% confidence intervals (CIs) were estimated for the trans population in Ontario and for the subgroup (n=167) reporting ED use in their felt gender. Four hundred eight participants completed the ED experience items. Trans people were young (34% aged 16 to 24 years and only 10% >55 years); approximately half were female-to-male and half male-to-female. Medically supervised hormones were used by 37% (95% CI 30% to 46%), and 27% (95% CI 20% to 35%) had at least 1 transition-related surgery. Past-year ED need was reported by 33% (95% CI 26% to 40%) of trans Ontarians, though only 71% (95% CI 40% to 91%) of those with self-reported need indicated that they were able to obtain care. An estimated 21% (95% CI 14% to 25%) reported ever avoiding ED care because of a perception that their trans status would negatively affect such an encounter. Trans-specific negative ED experiences were reported by 52% (95% CI 34% to 72%) of users presenting in their felt gender. This first exploratory analysis of ED avoidance, utilization, and experiences by trans persons documented ED avoidance and possible unmet need for emergency care among trans Ontarians. Additional research, including validation of measures, is needed. Copyright © 2013 American College of Emergency Physicians. Published by Mosby, Inc. All rights reserved.

Early Stigmatization, PTSD, and Perceived Negative Reactions of Others Predict Subsequent Strategies for Processing Child Sexual Abuse

PubMed Central

Simon, Valerie A.; Feiring, Candice; Cleland, Charles M.

2017-01-01

Objective Trauma processing is central to healthy recovery, but few studies examine how youth process experiences of child sexual abuse (CSA). The current study builds on our prior work identifying individual differences in CSA processing strategies (i.e., Constructive, Absorbed, Avoidant) to examine whether abuse stigmatization, PTSD symptoms, and negative reactions from others experienced during the year after abuse discovery were associated with subsequent CSA processing strategies. Method Participants included 160 ethnically diverse youth (8−15 years, 73% female) with confirmed cases of CSA. Predictors were measured at abuse discovery (T1) and 1 year later (T2). Individual differences in CSA processing strategies were assessed 6 years after discovery (T3) from participants’ abuse narratives. Results The persistence of abuse stigmatization from T1 to T2 significantly increased the odds of using either an Avoidant or Absorbed (vs. Constructive) strategy at T3. Higher levels of PTSD symptoms at T1 as well as their persistence from T1 to T2 each significantly increased the odds of having an Absorbed versus Constructive strategy. The persistence of perceived negative reactions from others from T1 to T2 increased the odds of an Absorbed versus Avoidant strategy. Effect sizes ranged from medium to large (M d = 0.636). Conclusions Results further validate prior work identifying distinct CSA processing strategies and suggest the persistence of abuse-specific disruptions over the year after abuse discovery may be associated with subsequent problems processing CSA experiences.

Is There a Paradox of Aging: When the Negative Aging Stereotype Meets the Positivity Effect in Older Adults.

PubMed

Zhou, Liqing; Lu, Jia; Chen, Guopeng; Dong, Li; Yao, Yujia

2017-01-01

Background/Study Context: Socioemotional selectivity theory (SST) states that the positivity effect is a result of older adults' emotion regulation and that older adults derive more emotional satisfaction from prioritizing positive information processing. The authors explored whether the positivity effect appeared when the negative aging stereotype was activated in older adults and also whether the effect differed between mixed and unmixed valence conditions. Sixty younger (18-23 years of age) and 60 older (60-87 years of age) adults were randomly assigned to a control group and a priming group, in which the negative aging stereotype was activated. All the participants were asked to select 15 words that best described the elderly from a mixed-word list (positive and negative words were mixed together) and from an unmixed-word list (positive and negative words were separated). Older adults in the control group selected more positive words, whereas among younger adults, selection did not differ by valence in either the mixed- or unmixed-word list conditions. There were no differences between the positive and negative word choices of the younger and older adults in the priming group. We calculated the differences between the numbers of positive and negative words, and the differences in the older adults' word choices were larger than those among the younger adults; the differences were also larger in the control group than in the priming group. The positivity effect worked by choosing positive stimuli rather than avoiding negative stimuli. The role of emotion regulation in older adults was limited, and when the positivity effect faced the effect of the negative aging stereotype, the negative stereotype effect was dominant. Future research should explore the changes in the positivity effect in the face of a positive aging stereotype and what roles other factors (e.g., activation level of the stereotype, arousal level of affective words) might play.

Vibration stress relief of DH 36 rectangle welded plates

Li, Shuqi; Fang, Hongyuan

2018-03-01

Vibration stress relief (VSR) is widely used in reducing residual stress in welded structures. However, the effectiveness of this method is still instable in some circumstance. In this study, a covert negative treatment phenomenon was investigated, i.e. natural frequency of welded structures decreased after VSR but residual stress in one direction increased. When the alteration of natural frequency after VSR is significant, the residual stresses in both the longitudinal and transversal directions shall decrease. Otherwise, residual stresses may increase on one direction. Thus, sufficient power shall be applied to the welded structures to avoid negative results.

Effects of buspirone on the immediate positive and delayed negative properties of intravenous cocaine as measured in the conditioned place preference test

PubMed Central

Ettenberg, Aaron; Bernardi, Rick E.

2007-01-01

In prior work, we have demonstrated that the behavioral effects of cocaine adhere to the predictions of the opponent-process theory of drug action. Animals develop conditioned place preferences for distinct locations paired with the immediate effects of IV cocaine, but learn to avoid places paired with the effects present 15-min post injection. It was of interest to assess the putative role of 5-HT in producing the negative properties of cocaine since cocaine acts to inhibit the reuptake of serotonin (5-HT) and since such actions have been associated with anxiogenic consequences. Male rats were administered a reinforcing dose of cocaine (1.0 mg/kg IV) and then placed – either immediately or after a 15-min delay -- into one side of a two-compartment (black-white) Conditioned Place Preference (CPP) box for 5-min. On alternate days, the animals received IV saline injections and were placed in the opposite side of the CPP box. This continued for eight days after which animals had experienced 4 pairings of cocaine with one side (black or white) of the CPP apparatus, and 4 saline pairings with the opposite side. Other groups of rats were treated identically except that 30-min prior to placement into the apparatus, these animals received an IP injection of saline or buspirone (a partial 5-HT1A agonist) at a dose that we have shown to be anxiolytic (2.5 mg/kg IP). Control animals experienced either buspirone or saline pretreatments without cocaine. Our results confirm that animals increase the time spent on the side paired with the immediate effects of cocaine (compared to baseline), but tend to avoid the side paired with effects present 15-min post-injection. Buspirone had no effect on the immediate rewarding properties of cocaine, but completely reversed the negative properties present 15-min post-cocaine. These results are consistent with the view that attenuation of 5-HT neurotransmission (via the autoreceptor agonist properties of buspirone) can reverse the negative impact of IV cocaine.

2018-02-01

To investigate the effects of ladle usage on the inclusions and total oxygen contents of bearing steel, MgO refractory rods with different glazes were used to simulate different ladle usages. The results show that the effects of different ladle usages on the cleanliness of the steel differ from each other. The total oxygen content of steel increases with the decreasing glaze basicity. Ladle glaze having a lower basicity has a more negative impact on the cleanliness of steel in the subsequent production. Inclusions can be generated by the flush-off of ladle glaze, and the initial glaze is important in the evolution of inclusions in the subsequent heats. To avoid the negative effect of ladle usage and to improve the steel cleanliness as much as possible, specialized ladles were suggested for producing high-quality steel grades.

Client Predictors of Short-term Psychotherapy Outcomes among Asian and White American Outpatients

2015-01-01

Purpose To examine predictors of psychotherapy outcomes, focusing on client characteristics that are especially salient for culturally diverse clients. Method Sixty clients (31 women; 27 White Americans, 33 Asian Americans) participated in this treatment study. Client characteristics were measured at pre-treatment, and outcomes were measured post-fourth session via therapist ratings of functioning and symptomatology. Regression analyses were utilized to test for predictors of outcomes, and bootstrap analyses were utilized to test for mediators. Results Higher levels of somatic symptoms predicted lower psychosocial functioning at post-treatment. Avoidant coping style predicted more negative symptoms and more psychological discomfort. Non-English language preference predicted worse outcomes; this effect was mediated by an avoidant coping style. Conclusions Language preference, avoidant coping style, and somatic symptoms predicted treatment outcome in a culturally diverse sample. Findings suggest that race/ethnicity-related variables may function through mediating proximal variables to affect outcomes. PMID:22836681

Attachment, social support, and responses following the death of a companion animal.

PubMed

King, Loren C; Werner, Paul D

This research tested hypotheses concerning attachment, social support, and grief responses to the loss of animal companionship. Participants whose companion cat or dog had recently died (N = 429) completed the Attachment Style Questionnaire, the Inventory of Complicated Grief, and the Multidimensional Health Profile-Psychosocial Functioning questionnaires. Both attachment anxiety and attachment avoidance were found to be positively associated with respondents' grief, depression, anxiety, and somatic symptoms. Social support was found to be negatively associated with these outcomes as well as with attachment anxiety and attachment avoidance. In multiple regression analyses, attachment anxiety incrementally predicted grief, anxiety and somatic symptoms, attachment avoidance incrementally predicted grief and depression, and social support incrementally predicted all outcomes. Interaction effects of attachment and social support in relation to outcomes were not found. The present study's implications and limitations are discussed, as are directions for future research.

In two studies (N = 416; N = 118) examining responses from undergraduates, we developed the Social Exercise and Anxiety Measure (SEAM) and tested its factorial, convergent, and divergent validity. Our results demonstrate that the SEAM exhibits an excellent three factor structure consisting of the following subscales: Social Exercise Self-efficacy, Gym Avoidance, and Exercise Importance. In both studies, Social Exercise Self-efficacy correlated negatively and Gym Avoidance correlated positively with social interaction anxiety, fear of scrutiny, and fear of negative evaluation. Exercise Importance correlated positively with frequency of exercise and frequency of public exercise. Implications for the mental and physical health of individuals with high levels of social anxiety are discussed. PMID:24244069

The effect of combined avoidance and control training on implicit food evaluation and choice.

PubMed

Kakoschke, Naomi; Kemps, Eva; Tiggemann, Marika

2017-06-01

Continual exposure to food cues in the environment contributes to unhealthy eating behaviour. According to dual-process models, such behaviour is partly determined by automatic processing of unhealthy food cues (e.g., approach bias), which fails to be regulated by controlled processing (e.g., inhibitory control). The current study aimed to investigate the effect of combined avoidance and control training on implicit evaluation (liking), choice, and consumption of unhealthy snack food. Participants were 240 undergraduate women who were randomly allocated to one of four experimental conditions of a 2 (avoidance training: training versus control) x 2 (control training: training versus control) between-subjects design. The combined training group had a more negative implicit evaluation of unhealthy food than either of the two training conditions alone or the control condition. In addition, participants trained to avoid unhealthy food cues subsequently made fewer unhealthy snack food choices. No significant group differences were found for food intake. Participants were women generally of a healthy weight. Overweight or obese individuals may derive greater benefit from combined training. Results lend support to the theoretical predictions of dual-process models, as the combined training reduced implicit liking of unhealthy food. At a practical level, the findings have implications for the effectiveness of interventions targeting unhealthy eating behaviour. Copyright © 2017 Elsevier Ltd. All rights reserved.

Empathy and avoidance in treating patients living with HIV/AIDS (PLWHA) among service providers in China

2012-01-01

This study aims to investigate health care providers’ empathy levels and its association with avoidance in providing service to patients living with HIV/AIDS (PLWHA) in China. A total of 1760 health service providers were randomly sampled from 40 county hospitals in two provinces of China. Using a self-administered questionnaire, participants’ demographic characteristics, work history, empathy level, and avoidance attitudes toward PLWHA were collected in a cross-sectional survey. Empathy was higher among participants aged 31–40 years, those who had an associated medical degree, and those who had served in the medical profession for less than 20 years. Nurses, younger providers, and providers with lower education tended to avoid contact with PLWHA. Multiple linear regression model showed that a higher level of empathic attitude toward patients was significantly negatively associated with avoidance attitude toward PLWHA. Service providers’ empathy level plays an important role in providing quality care to HIV-infected patients. Future stigma reduction interventions should cultivate empathy as a platform for understanding, effective communication, and trusting provider–patient relationships. PLWHA could potentially benefit from attitudinal change in medical settings. PMID:22292939

Lesions of the lateral habenula facilitate active avoidance learning and threat extinction.

PubMed

Song, Mihee; Jo, Yong Sang; Lee, Yeon-Kyung; Choi, June-Seek

2017-02-01

The lateral habenula (LHb) is an epithalamic brain structure that provides strong projections to midbrain monoaminergic systems that are involved in motivation, emotion, and reinforcement learning. LHb neurons are known to convey information about aversive outcomes and negative prediction errors, suggesting a role in learning from aversive events. To test this idea, we examined the effects of electrolytic lesions of the LHb on signaled two-way active avoidance learning in which rats were trained to avoid an unconditioned stimulus (US) by taking a proactive shuttling response to an auditory conditioned stimulus (CS). The lesioned animals learned the avoidance response significantly faster than the control groups. In a separate experiment, we also investigated whether the LHb contributes to Pavlovian threat (fear) conditioning and extinction. Following paired presentations of the CS and the US, LHb-lesioned animals showed normal acquisition of conditioned response (CR) measured with freezing. However, extinction of the CR in the subsequent CS-only session was significantly faster. The enhanced performance in avoidance learning and in threat extinction jointly suggests that the LHb normally plays an inhibitory role in learning driven by absence of aversive outcomes.

Density and delay of punishment of free-operant avoidance1

PubMed Central

Baron, Alan; Kaufman, Arnold; Fazzini, Dan

1969-01-01

In two experiments, the free-operant shock-avoidance behavior of rats was punished by electric shock. Two aspects of the schedule of response-produced shock were varied: the frequency of punishment over time (punishment density) and the temporal interval between the punished response and the punishment (punishment delay). The general finding was that response-produced shock suppressed avoidance responding under most of the density-delay combinations studied, and suppression increased as a function of increases in density and decreases in delay. Rate increases of small magnitude also were observed, usually as an initial reaction to the lesser densities and longer delays. Response suppression, while decreasing the number of punishment shocks received, also increased the number of avoidance shocks, so that the total number of shocks received usually was greater than the minimal number possible. The results were discussed from the standpoint of similarities between the effects of punishing positively and negatively reinforced behavior. The finding that subjects did not minimize the total number of shocks suggested that when avoidance behavior is punished, responding is controlled more by the local consequences of responding than by overall shock frequencies during the course of the session.

2016-11-01

Although college campuses represent strategic locations to address mental health disparity among minorities in the US, there has been strikingly little empirical work on risk processes for anxiety/depression among this population. The present investigation examined the interactive effects of acculturative stress and experiential avoidance in relation to anxiety and depressive symptoms among minority college students (n = 1,095; 78.1% female; Mage = 21.92, SD = 4.23; 15.1% African-American (non-Hispanic), 45.3% Hispanic, 32.5% Asian, and 7.1% other races/ethnicities. Results provided empirical evidence of an interaction between acculturative stress and experiential avoidance for suicidal, social anxiety, and anxious arousal symptoms among the studied sample. Inspection of the significant interactions revealed that acculturative stress was related to greater levels of suicidal symptoms, social anxiety, and anxious arousal among minority college students with higher, but not lower, levels of experiential avoidance. However, in contrast to prediction, there was no significant interaction for depressive symptoms. Together, these data provide novel empirical evidence for the clinically-relevant interplay between acculturative stress and experiential avoidance in regard to a relatively wide array of negative emotional states among minority college students.

It is not uncommon for people after a traumatic brain injury (TBI) to develop anxieties about possible negative outcomes (i.e., threat appraisals) in relation to participating in valued activities. Some respond to this anxiety by avoiding the activities, but others maintain their participation. The present study investigated two factors that may help explain this variation across individuals in their response to threat appraisals - self-esteem and the evaluation of coping resources. Forty-one individuals with a TBI completed the Avoidance and Threat Appraisals Questionnaire, the Rosenberg Self-Esteem Scale and the Coping Resources Questionnaire. The study's hypotheses were supported: Those low in self-esteem, and those with a negative evaluation of their ability to cope with the TBI, were significantly more likely to respond to threat appraisals with avoidance. Those whose injury was more recent and those whose injury was the result of an assault were also more likely to respond with avoidance. The theoretical and therapeutic implications of these results are discussed.

Context-dependent activation of reduced autobiographical memory specificity as an avoidant coping style.

2011-12-01

According to the affect-regulation hypothesis (Williams et al., 2007), reduced autobiographical memory specificity (rAMS) or overgeneral memory (OGM) might be considered a cognitive avoidance strategy; that is, people learn to avoid the emotionally painful consequences associated with the retrieval of specific negative memories. Based on this hypothesis, one would predict significant negative associations between AMS and avoidant coping. However, studies investigating this prediction have led to equivocal results. In the present study we tested a possible explanation for these contradictory findings. It was hypothesized that rAMS (in part) reflects an avoidant coping strategy, which might only become apparent under certain conditions, that is, conditions that signal the possibility of 'danger.' To test this hypothesis, we assessed AMS and behavioral avoidance but experimentally manipulated the instructions. In the neutral condition, two parallel versions of the Autobiographical Memory Test (AMT) were presented under neutral instructions. In the threat condition, the first AMT was presented under neutral instructions, while the second AMT was presented under 'threat instructions.' Results showed no significant correlations between avoidance and OGM under neutral conditions but significant and markedly stronger correlations under threat conditions, with more avoidance being associated with fewer specific and more categoric memories. In addition, high avoiders showed a stronger reduction in AMS in the threat condition as compared with the neutral condition, while low avoiders showed no such difference between conditions. The data confirm that OGM can be considered as part of a broader avoidant coping style. However, more importantly, they show that, at least in nonclinical individuals, the activation of this coping style may depend on the context. (c) 2011 APA, all rights reserved.

Loss aversion (LA), the idea that negative valuations have a higher psychological impact than positive ones, is considered an important variable in consumer research. The literature on aging and behavior suggests older individuals may show more LA, although it is not clear if this is an effect of aging in general (as in the continuum from age 20 and 50 years), or of the state of older age (e.g., past age 65 years). We also have not yet identified the potential biological effects of aging on the neural processing of LA. In the current study we used a cohort of subjects with a 30 year range of ages, and performed whole brain functional MRI (fMRI) to examine the ventral striatum/nucleus accumbens (VS/NAc) response during a passive viewing of affective faces with model-based fMRI analysis incorporating behavioral data from a validated approach/avoidance task with the same stimuli. Our a priori focus on the VS/NAc was based on (1) the VS/NAc being a central region for reward/aversion processing; (2) its activation to both positive and negative stimuli; (3) its reported involvement with tracking LA. LA from approach/avoidance to affective faces showed excellent fidelity to published measures of LA. Imaging results were then compared to the behavioral measure of LA using the same affective faces. Although there was no relationship between age and LA, we observed increasing neural differential sensitivity (NDS) of the VS/NAc to avoidance responses (negative valuations) relative to approach responses (positive valuations) with increasing age. These findings suggest that a central region for reward/aversion processing changes with age, and may require more activation to produce the same LA behavior as in younger individuals, consistent with the idea of neural efficiency observed with high IQ individuals showing less brain activation to complete the same task.

When pain meets … pain-related choice behavior and pain perception in different goal conflict situations.

Schrooten, Martien G S; Wiech, Katja; Vlaeyen, Johan W S

2014-11-01

Individuals in pain often face the choice between avoiding pain and pursuing other equally valued goals. However, little is known about pain-related choice behavior and pain perception in goal conflict situations. Seventy-eight healthy volunteers performed a computerized task requiring repeated choices between incompatible options, differing in their effect on probability to receive painful stimulation and money. Depending on group assignment, participants chose between increased pain probability versus decreased money probability (avoidance-avoidance conflict situation); decreased pain probability versus increased money probability (approach-approach conflict situation); or decrease versus increase in both probabilities (double approach/avoidance conflict situation). During the choice task, participants rated painfulness, unpleasantness, threat, and fearfulness associated with the painful stimulation and how they felt. Longer choice latency and more choice switching were associated with higher retrospective ratings of conflict and of decision difficulty, and more equal importance placed on pain avoidance and earning money. Groups did not differ in choice behavior, pain stimulus ratings, or affect. Across groups, longer choice latencies were nonsignificantly associated with higher pain, unpleasantness, threat, and fearfulness. In the avoidance-avoidance group, more choice switching was associated with higher pain-related threat and fearfulness, and with more negative affect. These results of this study suggest that associations between choice behaviors, pain perception, and affect depend on conflict situation. We present a first experimental demonstration of the relationship between pain-related choice behaviors, pain, and affect in different goal conflict situations. This experimental approach allows us to examine these relationships in a controlled fashion. Better understanding of pain-related goal conflicts and their resolution may lead to more effective pain treatment. Copyright © 2014 American Pain Society. Published by Elsevier Inc.

Brain Responses to Emotional Images Related to Cognitive Ability in Older Adults

Foster, Shannon M.; Davis, Hasker P.; Kisley, Michael A.

2013-01-01

Older adults have been shown to exhibit a positivity effect in processing of emotional stimuli, seemingly focusing more on positive than negative information. Whether this reflects purposeful changes or an unintended side-effect of declining cognitive abilities is unclear. For the present study older adults displaying a wide range of cognitive abilities completed measures of attention, visual and verbal memory, executive functioning, and processing speed, as well as a socioemotional measure of time perspective. Regression analyses examined the ability of these variables to predict neural responsivity to select emotional stimuli as measured with the late positive potential (LPP), an event-related brain potential (ERP). Stronger cognitive functioning was associated with higher LPP amplitude in response to negative images (i.e., greater processing). This does not support a voluntary avoidance of negative information processing in older adults for this particular measure of attentional allocation. A model is proposed to reconcile this finding with the extant literature that has demonstrated positivity effects in measures of later, controlled attentional allocation. PMID:23276213

A longitudinal analysis of drinking motives moderating the negative affect-drinking association among college students.

2010-03-01

We examined among college students (N = 530; 276 women) the moderating effects of avoidance (coping) and appetitive (social-enhancement) drinking motives on the within-person associations between anxious and depressive affect and drinking frequency and quantity. Once per year for up to 4 years participants completed standard measures of drinking motives and retrospective reports of affect and drinking in the previous month. In addition, each year they completed a 30-day daily diary of affect and drinking. Results from models examining both the retrospective and aggregate daily data indicated that individuals with high compared with low social-enhancement motives showed stronger positive associations among changes in monthly negative affect and drinking frequency. Weak evidence was found for the predicted moderating effects of coping motives, although some results indicated that its effects were contingent on levels of social-enhancement motives. Our findings suggest that appetitive drinking motives might play an integral role in stress- and negative-affect related drinking among college students.

Understanding shame in adults: retrospective perceptions of parental-bonding during childhood.

Lutwak, N; Ferrari, J R

1997-10-01

The association between perceptions of parental-bonding style during childhood and moral affect of shame at young adulthood were examined with 264 women and 140 men (mean age [+/- SD] = 20.4 +/- 1.6 years old). Shame affect was significantly positively related to fear of negative evaluation by others and social avoidance, and negatively related to recalled parental care in one's childhood. Multiple regression analyses indicated that maternal protectiveness, paternal care, fear of negative social evaluation, and social avoidance were significant predictors of shame, explaining 41% of the variance. Results support object relations theory, which states that shame is a moral affect associated with social evaluation apprehension and may have developmental implications for one's parental relations.

Assessing appetitive, aversive, and negative ethanol-mediated reinforcement through an immature rat model.

Pautassi, Ricardo M; Nizhnikov, Michael E; Spear, Norman E

2009-06-01

The motivational effects of drugs play a key role during the transition from casual use to abuse and dependence. Ethanol reinforcement has been successfully studied through Pavlovian and operant conditioning in adult rats and mice genetically selected for their ready acceptance of ethanol. Another model for studying ethanol reinforcement is the immature (preweanling) rat, which consumes ethanol and exhibits the capacity to process tactile, odor and taste cues and transfer information between different sensorial modalities. This review describes the motivational effects of ethanol in preweanling, heterogeneous non-selected rats. Preweanlings exhibit ethanol-mediated conditioned taste avoidance and conditioned place aversion. Ethanol's appetitive effects, however, are evident when using first- and second-order conditioning and operant procedures. Ethanol also devalues the motivational representation of aversive stimuli, suggesting early negative reinforcement. It seems that preweanlings are highly sensitive not only to the aversive motivational effects of ethanol but also to its positive and negative (anti-anxiety) reinforcement potential. The review underscores the advantages of using a developing rat to evaluate alcohol's motivational effects.

Data on long-term consequences of preterm birth on pain coping later in life are limited. To assess whether gestational age, birth weight and neonatal disease severity have effect on pain coping style in adolescents born preterm or with low birth weight. Observational, longitudinal study (Project On Preterm and SGA-infants, POPS-19). We analyzed data of 537 adolescents at the age of 19 years, who were born at a gestational age <32 weeks or with a birth weight <1500g. Participants completed the pain coping questionnaire (PCQ) that assesses pain coping strategies in three higher-order factors: approach ("to deal with pain"), problem-focused avoidance ("to disengage from pain") and emotion-focused avoidance ("expression of pain"). Furthermore, their pain coping effectiveness, pain controllability and emotional reactions to pain were assessed. All participants completed an IQ test. Univariate analysis showed no significant correlation between length of stay, sepsis and necrotizing enterocolitis and any of the higher-order factors. Approach was only correlated with IQ. Problem-focused avoidance was, in the multiple regression analysis (including gestational age, IVH and IQ), only correlated with IQ. For emotion-focused avoidance (including birth weight, SGA, IVH, respiratory support and IQ) three independent predictors remained: IVH was positively correlated, while respiratory support and IQ were negatively correlated with emotion-focused avoidance. Early neonatal characteristics and neonatal disease severity have limited effect on pain coping style in adolescence. Higher IQ was associated with the use of adaptive coping strategies, while maladaptive strategies were used less. Copyright © 2016. Published by Elsevier Ireland Ltd.

Contrasting motivational orientation and evaluative coding accounts: on the need to differentiate the effectors of approach/avoidance responses.

PubMed

Kozlik, Julia; Neumann, Roland; Lozo, Ljubica

2015-01-01

Several emotion theorists suggest that valenced stimuli automatically trigger motivational orientations and thereby facilitate corresponding behavior. Positive stimuli were thought to activate approach motivational circuits which in turn primed approach-related behavioral tendencies whereas negative stimuli were supposed to activate avoidance motivational circuits so that avoidance-related behavioral tendencies were primed (motivational orientation account). However, recent research suggests that typically observed affective stimulus-response compatibility phenomena might be entirely explained in terms of theories accounting for mechanisms of general action control instead of assuming motivational orientations to mediate the effects (evaluative coding account). In what follows, we explore to what extent this notion is applicable. We present literature suggesting that evaluative coding mechanisms indeed influence a wide variety of affective stimulus-response compatibility phenomena. However, the evaluative coding account does not seem to be sufficient to explain affective S-R compatibility effects. Instead, several studies provide clear evidence in favor of the motivational orientation account that seems to operate independently of evaluative coding mechanisms. Implications for theoretical developments and future research designs are discussed.

Violence Exposure and Psychopathology in Latino Youth: The Moderating Role of Active and Avoidant Coping.

Gudiño, Omar G; Stiles, Allison A; Diaz, Kathleen I

2018-06-01

Despite high rates of exposure to community violence among Latino youth in urban communities, there is considerable variability in individual outcomes. This study examined (a) associations between coping and indices of Latino culture, (b) main effects of active/avoidant coping on psychopathology, and (c) whether coping moderates the impact of violence exposure on mental health in Latino youth. Participants included 168 Latino youth (56% female; ages 11-14) that took part in a short-term longitudinal study. Results indicate that youth acculturation was positively associated with active coping, but enculturation level and immigrant status were not associated with coping. Structural equation models suggested that active coping was negatively associated with internalizing problems (p = .046) while avoidant coping was positively associated with internalizing problems (p = .013) and posttraumatic stress symptoms (p = .024). Moderation analyses revealed that violence exposure was more strongly associated with internalizing problems as reliance on avoidance coping increased. However, at high levels of violence exposure, a greater reliance on active coping was related to increased posttraumatic stress problems. Findings suggest that consideration of the specific stressor, level of stress exposure, and mental health problem-type may be crucial in determining the effectiveness of a coping strategy. Implications for future research and intervention are discussed.

Although cardiac stress testing may help establish the safety of early discharge in patients with suspected acute coronary syndromes and negative troponins, more cost-effective strategies are necessary. We aimed to develop a clinical prediction rule to safely obviate the need for cardiac stress testing in this setting. A decision rule was derived in a prospective cohort of 3001 patients with acute chest pain and negative troponins, and validated in a set of 1473 subjects. The primary end point was a composite of positive cardiac stress testing (in the absence of a subsequent negative coronary angiogram), positive coronary angiography, or any major coronary events within 3 months. A score chart was built based on 7 variables: male sex (+2), age (+1 per decade from the fifth decade), diabetes mellitus (+2), hypercholesterolemia (+1), prior coronary revascularization (+2), type of chest pain (typical angina, +5; non-specific chest pain, -3), and non-diagnostic repolarization abnormalities (+2). In the validation set, the model showed good discrimination (c statistic = 0.84; 95% confidence interval, 0.82-0.87) and calibration (Hosmer-Lemeshow goodness-of-fit test, P= .34). If stress tests were avoided in patients in the validation sample with a sum score of 0 or lower, the number of referrals would be reduced by 23.4%, yielding a negative predictive value of 98.8% (95% confidence interval, 97.0%-99.7%). This novel prediction rule based on a combination of readily available clinical characteristics may be a valuable tool to decide whether stress testing can be reliably avoided in patients with acute chest pain and negative troponins.

Embarrassment is emphasized, yet scantily described as a factor in extreme dental anxiety or phobia. Present study aimed to describe details of social aspects of anxiety in dental situations, especially focusing on embarrassment phenomena. Subjects (Ss) were consecutive specialist clinic patients, 16 men, 14 women, 20-65 yr, who avoided treatment mean 12.7 yr due to anxiety. Electronic patient records and transcribed initial assessment and exit interviews were analyzed using QSR"N4" software to aid in exploring contexts related to social aspects of dental anxiety and embarrassment phenomena. Qualitative findings were co-validated with tests of association between embarrassment intensity ratings, years of treatment avoidance, and mouth-hiding behavioral ratings. Embarrassment was a complaint in all but three cases. Chief complaints in the sample: 30% had fear of pain; 47% cited powerlessness in relation to dental social situations, some specific to embarrassment and 23% named co-morbid psychosocial dysfunction due to effects of sexual abuse, general anxiety, gagging, fainting or panic attacks. Intense embarrassment was manifested in both clinical and non-clinical situations due to poor dental status or perceived neglect, often (n = 9) with fear of negative social evaluation as chief complaint. These nine cases were qualitatively different from other cases with chief complaints of social powerlessness associated with conditioned distrust of dentists and their negative behaviors. The majority of embarrassed Ss to some degree inhibited smiling/laughing by hiding with lips, hands or changed head position. Secrecy, taboo-thinking, and mouth-hiding were associated with intense embarrassment. Especially after many years of avoidance, embarrassment phenomena lead to feelings of self-punishment, poor self-image/esteem and in some cases personality changes in a vicious circle of anxiety and avoidance. Embarrassment intensity ratings were positively correlated with years of avoidance and degree of mouth-hiding behaviors. Embarrassment is a complex dental anxiety manifestation with qualitative differences by complaint characteristics and perceived intensity. Some cases exhibited manifestations similar to psychiatric criteria for social anxiety disorder as chief complaint, while most manifested embarrassment as a side effect.

Harm avoidance in adolescents modulates late positive potentials during affective picture processing.

Research in adults has shown that individual differences in harm avoidance (HA) modulate electrophysiological responses to affective stimuli. To determine whether HA in adolescents modulates affective information processing, we collected event-related potentials from 70 adolescents while they viewed 90 pictures from the Chinese affective picture system. Multiple regressions revealed that HA negatively predicted late positive potential (LPP) for positive pictures and positively predicted for negative pictures; however, HA did not correlate with LPP for neutral pictures. The results suggest that at the late evaluative stage, high-HA adolescents display attentional bias to negative pictures while low-HA adolescents display attentional bias to negative pictures. Moreover, these dissociable attentional patterns imply that individual differences in adolescents' HA modulate the late selective attention mechanism of affective information. Copyright © 2013.

When someone is criticized for some failure or deficiency, he or she is faced with a dilemma about whether or how to respond. To date, most research on responses to criticism has adopted a communication approach and has focused on general social complaints. The present study instead adopted the perspective of stress and coping and aimed to delineate possible responses to criticism pertaining to one's physical appearance. We investigated the efficacy of three coping styles, namely acceptance, avoidance, and retaliation in explaining emotional reactions towards such criticism, and we additionally controlled for personality characteristics, in particular assertion and harmony beliefs. A sample of Taiwanese university students (N = 300) was surveyed for their coping styles and psychological outcomes, and personality traits were examined as possible predictors of response options. We found that (1) acceptance, retaliation, and avoidance were three broad coping styles in this problematic social situation; (2) the individual trait of assertion was negatively related to the use of avoidance, while harmony beliefs were positively related to acceptance and avoidance, but negatively related to retaliation; and (3) the use of acceptance and avoidance were positively related to positive emotions, whereas retaliation was positively related to negative emotions. Males tended to use more acceptance. Implications of these findings were discussed in relation to existing studies of communication, stress and coping. Possible influences of the Chinese collectivist culture on people's responses to criticism were also delineated, such as valuing interpersonal harmony and face-work in social situations.

Measuring the Cognitions, Emotions, and Motivation Associated With Avoidance Behaviors in the Context of Pain: Preliminary Development of the Negative Responsivity to Pain Scales.

2017-04-01

We recently proposed a Behavioral Inhibition System-Behavioral Activation System (BIS-BAS) model to help explain the effects of pain treatments. In this model, treatments are hypothesized to operate primarily through their effects on the domains within 2 distinct neurophysiological systems that underlie approach (BAS) and avoidance (BIS) behaviors. Measures of the model's domains are needed to evaluate and modify the model. An item pool of negative responses to pain (NRP; hypothesized to be BIS related) and positive responses (PR; hypothesized to be BAS related) were administered to 395 undergraduates, 325 of whom endorsed recurrent pain. The items were administered to 176 of these individuals again 1 week later. Analyses were conducted to develop and validate scales assessing NRP and PR domains. Three NRP scales (Despondent Response to Pain, Fear of Pain, and Avoidant Response to Pain) and 2 PR scales (Happy/Hopeful Responses and Approach Response) emerged. Consistent with the model, the scales formed 2 relatively independent overarching domains. The scales also demonstrated excellent internal consistency, and associations with criterion variables supported their validity. However, whereas the NRP scales evidenced adequate test-retest stability, the 2 PR scales were not adequately stable. The study yielded 3 brief scales assessing NRP, which may be used to further evaluate the BIS-BAS model and to advance research elucidating the mechanisms of psychosocial pain treatments. The findings also provide general support for the BIS-BAS model, while also suggesting that some minor modifications in the model are warranted.

Introduction Empirical work has documented a robust and consistent relation between panic attacks and smoking behavior. Theoretical models posit smokers with panic attacks may rely on smoking to help them manage chronically elevated negative affect due to uncomfortable bodily states, which may explain higher levels of nicotine dependence and quit problems. Methods The current study examined the effects of panic attack history on nicotine dependence, perceived barriers for quitting, smoking inflexibility when emotionally distressed, and expired carbon monoxide among 461 treatment-seeking smokers. A multiple mediator path model was evaluated to examine the indirect effects of negative affect and negative affect reduction motives as mediators of the panic attack-smoking relations. Results Panic attack history was indirectly related to greater levels of nicotine dependence (b=0.039, CI95%=0.008, 0.097), perceived barriers to smoking cessation (b=0.195, CI95%=0.043, 0.479), smoking inflexibility/avoidance when emotionally distressed (b=0.188, CI95%=0.041, 0.445), and higher levels of expired carbon monoxide (b=0.071, CI95%=0.010, 0.230) through the sequential effects of negative affect and negative affect smoking motives. Conclusions The present results provide empirical support for the sequential mediating role of negative affect and smoking motives for negative affect reduction in the relation between panic attacks and a variety of smoking variables in treatment-seeking smokers. These mediating variables are likely important processes to address in smoking cessation treatment, especially in panic-vulnerable smokers. PMID:24720260

Empirical work has documented a robust and consistent relation between panic attacks and smoking behavior. Theoretical models posit smokers with panic attacks may rely on smoking to help them manage chronically elevated negative affect due to uncomfortable bodily states, which may explain higher levels of nicotine dependence and quit problems. The current study examined the effects of panic attack history on nicotine dependence, perceived barriers for quitting, smoking inflexibility when emotionally distressed, and expired carbon monoxide among 461 treatment-seeking smokers. A multiple mediator path model was evaluated to examine the indirect effects of negative affect and negative affect reduction motives as mediators of the panic attack-smoking relations. Panic attack history was indirectly related to greater levels of nicotine dependence (b = 0.039, CI95% = 0.008, 0.097), perceived barriers to smoking cessation (b = 0.195, CI95% = 0.043, 0.479), smoking inflexibility/avoidance when emotionally distressed (b = 0.188, CI95% = 0.041, 0.445), and higher levels of expired carbon monoxide (b = 0.071, CI95% = 0.010, 0.230) through the sequential effects of negative affect and negative affect smoking motives. The present results provide empirical support for the sequential mediating role of negative affect and smoking motives for negative affect reduction in the relation between panic attacks and a variety of smoking variables in treatment-seeking smokers. These mediating variables are likely important processes to address in smoking cessation treatment, especially in panic-vulnerable smokers.

Individuals with substance abuse (SA) histories show impairment in the computations necessary for decision-making, including expected value (EV) and prediction error (PE). Neuroimaging findings, however, have been inconsistent. Sixteen youth with (SA positive ) and 29 youth without (SA negative ) substance abuse histories completed a passive avoidance task while undergoing functional MRI. The groups did not significantly differ on age, gender composition or IQ. Behavioral results indicated that SA positive youth showed significantly less learning than SA negative youth over the task. SA positive youth show problems representing EV information when attempting to avoid sub-optimal choices in bilateral inferior frontal gyrus and striatum. Furthermore, SA positive youth showed a significantly increased differential response to reward versus punishment feedback modulated by PE in posterior cingulate cortex relative to SA negative youth. Disrupted decision-making is likely to exacerbate SA as a failure to represent EV during the avoidance of sub-optimal choices is likely to increase the likelihood of SA. With respect to the representation of PE, future work will be needed to clarify the impact of different substances on the neural systems underpinning PE representation. Moreover, interaction of age/development and substance abuse on PE signaling will need to be explored. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Keep your eyes open: dispositional vigilance moderates the relationship between operational police stress and stress symptoms.

PubMed

Vigilant coping is characterized by a deep processing of threat-related information. In many cases, vigilant coping increases stress symptoms, whereas avoidant coping decreases negative affect. However, vigilance may be beneficial when stress-eliciting situations involve a risk of injury or escalation as is usually the case in police operations. We investigated the roles of vigilance and cognitive avoidance in police operations in a cross-sectional survey. The participants were 137 students (104 men, M age  = 28.54, SD = 8.04) from the Federal University of Applied Administrative Sciences; 76 of them were already police officers (work experience: M = 12.59 years), and 61 were police officer candidates who had completed a 3- to 6-month police internship. Participants completed a paper-and-pencil survey and reported their operational stress, dispositional vigilance and cognitive avoidance in police operations, and stress symptoms. We found that vigilance was negatively associated with stress symptoms and moderated the relationship between operational stress and stress symptoms. Cognitive avoidance, on the other hand, just missed the level of statistical significance in our test of whether it was positively associated with stress symptoms. Our findings demonstrate that vigilance may protect against the negative consequences of stress in police operations.

Development and validation of two measures of emotional contrast avoidance: The contrast avoidance questionnaires.

PubMed

Llera, Sandra J; Newman, Michelle G

2017-06-01

The Contrast Avoidance (CA) model (Newman & Llera, 2011) proposed that individuals with generalized anxiety disorder (GAD) fear sharp emotional shifts (or contrasts), such as the shift from a pleasant or neutral state to one of sudden distress following a negative event. Further, the model suggests that chronic worry is employed by those with GAD to sustain negative emotionality as a means to avoid sudden shifts into negativity. The model has received empirical support; however, no validated measure exists to assess CA tendencies. In this paper we developed and tested two measures of CA: one focusing on worry, and another examining broader mechanisms of CA that could be used test whether CA is applicable to other disorders. In Study 1, Part 1, we used 3 samples of participants (each N=410) to perform item reduction, exploratory factor analysis, and confirmatory factor analysis. In Study 1, Part 2, we performed tests of construct validity. In Study 2, we used a new sample (N=126) to determine test-retest reliability. All data point to the strong psychometric properties of the CA questionnaires and their relationship to GAD. Both measures distinguished between participants reporting clinical levels of GAD symptoms and nonanxious controls, demonstrating their utility as complementary measures of CA tendencies.

Researchers have suggested that older adults express less negative emotions. Yet, emotional expression patterns in older and younger breast cancer survivors, have barely been examined. This study aimed to explore types and intensity of negative and positive emotional expression related to the breast cancer experience by younger and older Arab breast cancer survivors. Participants were 20 younger (aged 32-50) and 20 older (aged 51-75) Muslim and Christian Arab breast cancer survivors (stages I-III), currently free of disease. Data were gathered through in-depth semi-structured interviews. Mixed methods analyses were conducted, including: (1) frequency analysis of participants' emotional expressions; (2) content analysis of emotional expressions, categorized according to negative and positive emotions. Three emotional expression modalities were revealed: (1) Succinct versus comprehensive accounts; (2) expression of emotions versus avoidance of emotions; (3) patterns of expression of positive emotions and a sense of personal growth. Younger women provided more detailed accounts about their illness experiences than older women. Older women's accounts were succinct, action-focused, and included more emotion-avoiding expressions than younger women. Understanding the relationships between emotional expression, emotional experience, and cancer survivors' quality of life, specifically of those from traditional communities, is necessary for developing effective psycho-social interventions.

2007-08-01

Memory encoding and retrieval were studied in a nonclinical sample of participants that differed in the amount of reported dissociative experiences (trait dissociation). Behavioral as well as functional imaging (fMRI) indices were used as convergent measures of memory functioning. In a deep vs. shallow encoding paradigm, the influence of dissociative style on elaborative and avoidant encoding was studied, respectively. Furthermore, affectively neutral and negative words were presented, to test whether the effects of dissociative tendencies on memory functioning depended on the affective valence of the stimulus material. Results showed that (a) deep encoding of negative vs. neutral stimuli was associated with higher levels of semantic elaboration in high than in low dissociators, as indicated by increased levels of activity in hippocampus and prefrontal cortex during encoding and higher memory performance during recognition, (b) high dissociators were generally characterized by higher levels of conscious recollection as indicated by increased activity of the hippocampus and posterior parietal areas during recognition, (c) nonclinical high dissociators were not characterized by an avoidant encoding style. These results support the notion that trait dissociation in healthy individuals is associated with high levels of elaborative encoding, resulting in high levels of conscious recollection. These abilities, in addition, seem to depend on the salience of the presented stimulus material.

Can operating companies cost-effectively manage environmental risks, meet compliance requirements and attain financial and market-oriented goals? Yes, if top management fully supports incorporating environmental-risk issues into the corporate management system. Using evaluation tools such as risk assessment and environmental audits, operators can fully define their environment condition and risk level. Working these results, HPI companies can take action to reduce the probability of environmental accidents and mitigate adverse event effects. Adopting this top-down, proactive outlook, organizations can evade environmental catastrophes, avoid negative public image and prevent ruined reputations.

Adolescent attachment styles and their relation to the temperament and character traits of personality in a general population.

Attachment styles as well as personality traits in adolescents and adults have been found to be associated with their health outcomes and with their personality pathology. In this cross-sectional exploratory study, we study the relationship between attachment styles that derive from our data employing the items of Feeney et al. (1994) self-report attachment style questionnaire (ASQ), and personality traits given by the junior version of Cloninger et al. (1993) self-report temperament and character inventory (TCI), in a sample of 426 adolescents (54% females) from a general population. The secure attachment style was correlated significantly negatively with the personality trait harm avoidance (HA), but significantly positively with the personality traits novelty seeking (NS), reward dependence (RD), cooperativeness (CO) and self-transcendence (ST). The preoccupied (anxious/ambivalent) attachment style was correlated significantly positively with HA and NS, but significantly negatively with self-directedness (SD). The fearful-avoidant category was correlated significantly negatively with NS. Our five-factor solution of the attachment styles and their relation to the TCI point towards a need for a modification of the two-axis, four-category attachment model of Bartholomew (1990) and Bartholomew and Horowitz (1991), with their category dismissing-avoidant replaced by the two categories defined here as dismissing relations (correlated significantly negatively with CO) and dismissing others (correlated significantly negatively with RD and significantly positively with SD).

Now You See it, Now You Don't: Age Differences in Affective Reactivity to Social Tensions

When faced with interpersonal conflict, older adults report using passive strategies more often than do younger adults. They also report less affective reactivity in response to these tensions. We examined whether the use of passive strategies may explain age-related reductions in affective reactivity to interpersonal tensions. Over eight consecutive evenings, participants (N = 1031, 25 – 74 years-old) reported daily negative affect and the occurrence of tense situations where they had an argument or avoided an argument. Older age was related to less affective reactivity when people decided to avoid an argument but was unrelated to affective reactivity when people engaged in arguments. Findings suggest that avoidance of negative situations may largely underlie age-related benefits in affective well-being. PMID:19739920

Oxytocin attenuates social and non-social avoidance: Re-thinking the social specificity of Oxytocin.

PubMed

2017-07-01

Re-examining decades of the social construal of Oxytocin, the General Approach-Avoidance Hypothesis of Oxytocin (GAAO) predicts that Oxytocin will modulate responding to emotionally-evocative and personally-relevant social and non-social stimuli due to its action on the neural substrate of approach and avoidance motivation. We report the first critical experimental test of GAAO predictions by means of a double-blind intra-nasal administration of Oxytocin vs. placebo in 90 healthy adults (N=90, 50% women). As predicted, we found that among men and women for whom negative emotion (anxious arousal) is motivationally-relevant, intra-nasal administration of Oxytocin reduced behavioral avoidance of emotionally-evocative negatively-valenced social and non-social stimuli, but not closely matched emotionally-neutral stimuli. Findings cannot be explained by extant social theories of Oxytocin. We discuss the implications of the present findings for basic and translational clinical Oxytocin research.

An improved method for large-scale preparation of negatively and positively supercoiled plasmid DNA.

PubMed

Barth, Marita; Dederich, Debra; Dedon, Peter

2009-07-01

A rigorous understanding of the biological function of superhelical tension in cellular DNA requires the development of new tools and model systems for study. To this end, an ethidium bromide[#x02013]free method has been developed to prepare large quantities of either negatively or positively super-coiled plasmid DNA. The method is based upon the known effects of ionic strength on the direction of binding of DNA to an archaeal histone, rHMfB, with low and high salt concentrations leading to positive and negative DNA supercoiling, respectively. In addition to fully optimized conditions for large-scale (>500 microg) supercoiling reactions, the method is advantageous in that it avoids the use of mutagenic ethidium bromide, is applicable to chemically modified plasmid DNA substrates, and produces both positively and negatively supercoiled DNA using a single set of reagents.

The current study examines anxiety and age associations with attention allocation and physiological response to threats and rewards. Twenty-two healthy-adults, 20 anxious-adults, 26 healthy-youth, and 19 anxious-youth completed two eye-tracking tasks. In the Visual Scene Task (VST), participants' fixations were recorded while they viewed a central neutral image flanked by two threatening or two rewarding stimuli. In the Negative Words Task (NWT), physiological response was measured by means of pupil diameter change while negative and neutral words were presented. For both tasks, no interaction was found between anxiety and age-group. In the VST, anxious participants avoided the threatening images when groups were collapsed across age. Similarly, adults but not adolescents avoided the threatening images when collapsed across anxiety. No differences were found for rewarding images. In NWT, all subjects demonstrated increase in pupil dilation after word presentation. Only main effect of age emerged with stronger pupil dilation in adults than children. Finally, maximum pupil change was correlated with threat avoidance bias in the scene task. Gaze patterns and pupil dilation show that anxiety and age are associated with attention allocation to threats. The relations between attention and autonomic arousal point to a complex interaction between bottom-up and top-down processes as they relate to attention allocation. Copyright © 2015 Elsevier B.V.

The Role of Motivation in Cognitive Reappraisal for Depressed Patients

2017-01-01

Background: People engage in emotion regulation in service of motive goals (typically, to approach a desired emotional goal or avoid an undesired emotional goal). However, how motives (goals) in emotion regulation operate to shape the regulation of emotion is rarely known. Furthermore, the modulatory role of motivation in the impaired reappraisal capacity and neural abnormalities typical of depressed patients is not clear. Our hypothesis was that (1) approach and avoidance motivation may modulate emotion regulation and the underlying neural substrates; (2) approach/avoidance motivation may modulate emotion regulation neural abnormalities in depressed patients. Methods: Twelve drug-free depressed patients and fifteen matched healthy controls reappraised emotional pictures with approach/avoidant strategies and self-rated their emotional intensities during fMRI scans. Approach/avoidance motivation was measured using Behavioral Inhibition System and Behavioral Activation System (BIS/BAS) Scale. We conducted whole-brain analyses and correlation analyses of regions of interest to identify alterations in regulatory prefrontal-amygdala circuits which were modulated by motivation. Results: Depressed patients had a higher level of BIS and lower levels of BAS-reward responsiveness and BAS-drive. BIS scores were positively correlated with depressive severity. We found the main effect of motivation as well as the interactive effect of motivation and group on the neural correlates of emotion regulation. Specifically, hypoactivation of IFG underlying the group differences in the motivation-related neural correlates during reappraisal may be partially explained by the interaction between group and reappraisal. Consistent with our prediction, dlPFC and vmPFC was differentially between groups which were modulated by motivation. Specifically, the avoidance motivation of depressed patients could predict the right dlPFC activation during decreasing positive emotion, while the approach motivation of normal individuals could predict the right vmPFC activation during decreasing negative emotion. Notably, striatal regions were observed when examining the neural substrates underlying the main effect of motivation (lentiform nucleus) and the interactive effect between motivation and group (midbrain). Conclusions: Our findings highlight the modulatory role of approach and avoidance motivation in cognitive reappraisal, which is dysfunctional in depressed patients. The results could enlighten the CBT directed at modifying the motivation deficits in cognitive regulation of emotion. PMID:29163097

To observe the early prevention effect of the compound nutrients recipe for cognitive dysfunction of Alzheimer' s disease model-APP-PSN transgenic mouse. 36 APP-PSN transgenic mice aged two months randomly were divided into the intervention group supplied with compound recipe in the diet and the control group fed based feed, the former had high dose and low dose, 12 APP-PSN transgenic negative mice aged two months as the negative control were fed based feed. After 3 months' intervention, four groups' cognitive functions were evaluated using the Morris water maze, active avoidance experiment and jumping stair experiment. There was not statistically different between all the four groups for the weight and food intake. Compared with the control group, Morris water maze's incubation period of the intervention group was lower obviously, and jumping stair experiment's incubation period of the intervention group was higher obviously. In the active avoidance experiment, the high and low dose intervention group' s conditioned response accounted about 46.67% and 45.00% respectively, and the control group's conditioned response accounted about 20.83%. The differences of the three behavioral experiments between control group and intervention group had the statistical significance (P < 0.05), so the same as between control group and negative control group (P < 0.05). And there was no difference between intervention group and negative control group for the three behavioral experiments. The early supplementation with compound nutrition could postpone the occurrence and development of Alzheimer' s disease mice model's cognitive dysfunction.

Coping, stress, and the psychological symptoms of children of divorce: a cross-sectional and longitudinal study.

The authors conducted a cross-sectional and prospective longitudinal study of stress, coping, and psychological symptoms in children of divorce. The sample consisted of 258 children (mean age = 10.1; SD = 1.2), of whom 196 were successfully followed 5.5 months later. A 4-dimensional model of coping was found using confirmatory factor analysis, with the factors being active coping, avoidance, distraction, and support. In the cross-sectional model avoidance coping partially mediated the relations between negative events and symptoms while active coping moderated the relations between negative events and conduct problems. In the longitudinal model significant negative paths were found from active coping and distraction Time 1 to internalizing symptoms Time 2, while Time 1 support coping had a positive path coefficient to Time 2 depression. Positive paths were found between negative events at Time 1 and anxiety at Time 2, and between all symptoms at Time 1 and negative events at Time 2.

Maternal Frontal EEG Asymmetry and Chronic Stressors Moderate the Link between Child Conduct Problems and Maternal Negativity

2016-01-01

Frontal EEG asymmetry is associated with individual differences in positive/negative emotionality and approach/avoidance tendencies. The current study examined the moderating role of maternal resting frontal EEG asymmetry on the link between child behavior problems and maternal harsh parenting, within the context of differing degrees of chronic family stressors (father unemployment, single parenthood, caring for multiple children, and household chaos). The sample included 121 mother-child pairs. Results showed that stressors and frontal EEG asymmetry together moderated the link. Child problem behaviors were moderately associated with greater maternal negativity for mothers with right frontal asymmetry, or mothers who experienced more stressors. However, no association existed between child behavior problems and maternal negativity for mothers with few stressors and left frontal asymmetry. The findings implicate transactions between household stress and a psychophysiological indicator of maternal emotional reactivity and mothers’ approach/avoidance tendencies, in the etiology of parental negativity toward challenging child behaviors.

Nocebo phenomena in medicine: their relevance in everyday clinical practice.

PubMed

Häuser, Winfried; Hansen, Ernil; Enck, Paul

2012-06-01

Nocebo phenomena are common in clinical practice and have recently become a popular topic of research and discussion among basic scientists, clinicians, and ethicists. We selectively searched the PubMed database for articles published up to December 2011 that contained the key words "nocebo" or "nocebo effect." By definition, a nocebo effect is the induction of a symptom perceived as negative by sham treatment and/or by the suggestion of negative expectations. A nocebo response is a negative symptom induced by the patient's own negative expectations and/or by negative suggestions from clinical staff in the absence of any treatment. The underlying mechanisms include learning by Pavlovian conditioning and reaction to expectations induced by verbal information or suggestion. Nocebo responses may come about through unintentional negative suggestion on the part of physicians and nurses. Information about possible complications and negative expectations on the patient's part increases the likelihood of adverse effects. Adverse events under treatment with medications sometimes come about by a nocebo effect. Physicians face an ethical dilemma, as they are required not just to inform patients of the potential complications of treatment, but also to minimize the likelihood of these complications, i.e., to avoid inducing them through the potential nocebo effect of thorough patient information. Possible ways out of the dilemma include emphasizing the fact that the proposed treatment is usually well tolerated, or else getting the patient's permission to inform less than fully about its possible side effects. Communication training in medical school, residency training, and continuing medical education would be desirable so that physicians can better exploit the power of words to patients' benefit, rather than their detriment.

Investigating the genetic and environmental bases of biases in threat recognition and avoidance in children with anxiety problems

PubMed Central

2012-01-01

Background Adults with anxiety show biased categorization and avoidance of threats. Such biases may emerge through complex interplay between genetics and environments, occurring early in life. Research on threat biases in children has focuses on a restricted range of biases, with insufficient focus on genetic and environmental origins. Here, we explore differences between children with and without anxiety problems in under-studied areas of threat bias. We focused both on associations with anxious phenotype and the underlying gene-environmental correlates for two specific processes: the categorisation of threat faces and avoidance learning. Method Two-hundred and fifty 10-year old MZ and DZ twin pairs (500 individuals) completed tasks assessing accuracy in the labelling of threatening facial expressions and in the acquisition of avoidant responses to a card associated with a masked threatening face. To assess whether participants met criteria for an anxiety disorder, parents of twins completed a self-guided computerized version of the Development and Well-being Assessment (DAWBA). Comparison of MZ and DZ twin correlations using model-fitting were used to compute estimates of genetic, shared and non-shared environmental effects. Results Of the 500 twins assessed, 25 (5%) met diagnostic criteria for a current anxiety disorder. Children with anxiety disorders were more accurate in their ability to recognize disgust faces than those without anxiety disorders, but were commensurate on identifying other threatening face emotions (angry, fearful, sad). Children with anxiety disorders but also more strongly avoided selecting a conditioned stimulus than non-anxious children. While recognition of socially threatening faces was moderately heritable, avoidant responses were heavily influenced by the non-shared environment. Conclusion These data add to other findings on threat biases in anxious children. Specifically, we found biases in the labelling of some negative-valence faces and in the acquisition of avoidant responses. While non-shared environmental effects explained all of the variance on threat avoidance, some of this may be due to measurement error. PMID:22788754

Overcharge tolerant high-temperature cells and batteries

DOEpatents

Redey, Laszlo; Nelson, Paul A.

1989-01-01

In a lithium-alloy/metal sulfide high temperature electrochemical cell, cell damage caused by overcharging is avoided by providing excess lithium in a high-lithium solubility phase alloy in the negative electrode and a specified ratio maximum of the capacity of a matrix metal of the negative electrode in the working phase to the capacity of a transition metal of the positive electrode. In charging the cell, or a plurality of such cells in series and/or parallel, chemical transfer of elemental lithium from the negative electrode through the electrolyte to the positive electrode provides sufficient lithium to support an increased self-charge current to avoid anodic dissolution of the positive electrode components above a critical potential. The lithium is subsequently electrochemically transferred back to the negative electrode in an electrochemical/chemical cycle which maintains high self-discharge currents on the order of 3-15 mA/cm.sup.2 in the cell to prevent overcharging.

Homeostasis is a biological principle for regulation of essential physiological parameters within a set range. Behavioural responses due to deviation from homeostasis are critical for survival, but motivational processes engaged by physiological need states are incompletely understood. We examined motivational characteristics of two separate neuron populations that regulate energy and fluid homeostasis by using cell-type-specific activity manipulations in mice. We found that starvation-sensitive AGRP neurons exhibit properties consistent with a negative-valence teaching signal. Mice avoided activation of AGRP neurons, indicating that AGRP neuron activity has negative valence. AGRP neuron inhibition conditioned preference for flavours and places. Correspondingly, deep-brain calcium imaging revealed that AGRP neuron activity rapidly reduced in response to food-related cues. Complementary experiments activating thirst-promoting neurons also conditioned avoidance. Therefore, these need-sensing neurons condition preference for environmental cues associated with nutrient or water ingestion, which is learned through reduction of negative-valence signals during restoration of homeostasis.

False beliefs about fattening foods can have healthy consequences

2005-01-01

We suggested to 228 subjects in two experiments that, as children, they had had negative experiences with a fattening food. An additional 107 subjects received no such suggestion and served as controls. In Experiment 1, a minority of subjects came to believe that they had felt ill after eating strawberry ice cream as children, and these subjects were more likely to indicate not wanting to eat strawberry ice cream now. In contrast, we were unable to obtain these effects when the critical item was a more commonly eaten treat (chocolate chip cookie). In Experiment 2, we replicated and extended the strawberry ice cream results. Two different ways of processing the false suggestion succeeded in planting the false belief and producing avoidance of the food. These findings show that it is possible to convince people that, as children, they experienced a negative event involving a fattening food and that this false belief results in avoidance of that food in adulthood. More broadly, these results indicate that we can, through suggestion, manipulate nutritional selection and possibly even improve health. PMID:16079200

All subjects underwent a psychometric examination with the following instruments: Temperament and Character Inventory (TCI) and Sex and the Average Woman (or Man; SAWM). The best negative predictor of Sexual Excitement and Satisfaction was the temperamental dimension Harm Avoidance; as it regards character dimensions, Cooperativeness was the best negative predictor of Sexual Excitement, while Self-Directedness was the best positive predictor of Sexual Satisfaction. Overall, inhibitory aspects of the personality have deeper effects on sexual motivation than excitatory ones. The results of this research suggest the importance of studying the relationship between personality and sexual behavior. An integrative psychobiological approach to the study of sexual excitement and satisfaction may give a fundamental contribution to the assessment and psychological treatment of predisposing personality factors (like avoidant tendencies) involved in the development and persistence of sexual dysfunction.

Punishing errors facilitates adaptation in healthy individuals, while aberrant reward and punishment sensitivity in drug-dependent individuals may change this impact. Many societies have institutions that use the concept of punishing drug use behavior, making it important to understand how drug dependency mediates the effects of negative feedback for influencing adaptive behavior. Using an associative learning task, we investigated differences in error correction rates of dependent smokers, compared with controls. Two versions of the task were administered to different participant samples: One assessed the effect of varying monetary contingencies to task performance, the other, the presence of reward as compared to avoidance of punishment for correct performance. While smokers recalled associations that were rewarded with a higher value 11% more often than lower rewarded locations, they did not correct higher punished locations more often. Controls exhibited the opposite pattern. The three-way interaction between magnitude, feedback type and group was significant, F(1,48) = 5.288, p =0.026, ɳ 2 p =0.099. Neither participant group corrected locations offering reward more often than those offering avoidances of punishment. The interaction between group and feedback condition was not significant, F(1,58) = 0.0, p =0.99, ɳ 2 p =0.001. The present results suggest that smokers have poorer learning from errors when receiving negative feedback. Moreover, larger rewards reinforce smokers' behavior stronger than smaller rewards, whereas controls made no distinction. These findings support the hypothesis that dependent smokers may respond to positively framed and rewarded anti-smoking programs when compared to those relying on negative feedback or punishment.

Predictors of experiences of discrimination and positive treatment in people with mental health problems: findings from an Australian national survey.

PubMed

Reavley, Nicola J; Morgan, Amy J; Jorm, Anthony F

2017-03-01

The aim of the study was to assess the factors predicting experiences of avoidance, discrimination and positive treatment in people with mental health problems. In 2014, telephone interviews were carried out with 5220 Australians aged 18+, 1381 of whom reported a mental health problem or scored highly on a symptom screening questionnaire. Questions covered experiences of avoidance, discrimination and positive treatment by friends, spouse, other family, workplace, educational institution and others in the community; as well as disclosure of mental health problems. Avoidance, discrimination and positive treatment scores were calculated by counting the number of domains in which each occurred. Predictors of avoidance, discrimination and positive treatment were modelled with negative binomial regression analyses. After adjusting for the effects of other predictors in multivariate analyses, symptom severity and a diagnosis of 'any other disorder' (most commonly psychotic disorders or eating disorders) predicted experiences of both avoidance and discrimination but not positive treatment. Disclosing a mental health problem in more settings was also associated with higher rates of avoidance and discrimination, but also with positive treatment. Disclosure of mental health problems to others may increases experiences of discrimination, but may also increase experiences of positive treatment. These findings can help to inform decision making by people with mental health problems about disclosure, particularly in the case of more severe or low-prevalence disorders.

Use of negative pressure wound therapy with instillation in the management of cervical necrotizing fasciitis.

2015-11-01

Cervical necrotizing fasciitis is an aggressive infection that can be rapidly fatal if aggressive therapies are not initiated early. Negative pressure wound therapy has been established as an effective tool in promoting wound healing, but its use in the acutely infected wound has been avoided because it limits frequent irrigations and standard dressing changes. We discuss a novel application of negative pressure wound therapy with instillation in an immunocompromised patient with extensive cervical necrotizing fasciitis. The negative pressure wound therapy with instillation provided pain relief by minimizing the frequency of dressing changes, increased the speed of healing, helped to control infection, and facilitated the development of a healthy wound bed sufficient for reconstruction with a split thickness skin graft. The role of negative pressure wound therapy with instillation continues to expand and can be used in the management of both acute and chronic wounds in the head and neck. © 2015 Wiley Periodicals, Inc.

Predictors of urge to smoke under stressful conditions: An experimental investigation utilizing the PASAT-C task to induce negative affect in smokers.

PubMed

Karekla, Maria; Panayiotou, Georgia; Collins, Bradley N

2017-11-01

Experimental evidence has demonstrated that the presence of cues previously associated with smoking behavior can increase urges to smoke in abstinent smokers. This study examined the effect of a laboratory-induced negative affective task (paced auditory serial addition task) on smoking urges among a sample of 35 abstinent college smokers (Mage = 20.83 years, SD = 1.71). Emotional states and physiological reactions experienced during the experiment, as well as individual differences in stress intolerance (anxiety sensitivity and experiential avoidance) were examined as predictors of the association between stressful states and smoking cravings. Smoking urges (smoking desire and negative affect relief) and negative emotions (frustration, irritability, stress) significantly increased, whereas positive emotions decreased from pre- to posttask. No significant interactions between individual differences and changes in urge were found. Results suggest that changes in negative affect may in part explain the association between induced stress and smoking cravings. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Feed‐backs among inbreeding, inbreeding depression in sperm traits, and sperm competition can drive evolution of costly polyandry

PubMed Central

Bocedi, Greta; Reid, Jane M.

2017-01-01

Abstract Ongoing ambitions are to understand the evolution of costly polyandry and its consequences for species ecology and evolution. Emerging patterns could stem from feed‐back dynamics between the evolving mating system and its genetic environment, defined by interactions among kin including inbreeding. However, such feed‐backs are rarely considered in nonselfing systems. We use a genetically explicit model to demonstrate a mechanism by which inbreeding depression can select for polyandry to mitigate the negative consequences of mating with inbred males, rather than to avoid inbreeding, and to elucidate underlying feed‐backs. Specifically, given inbreeding depression in sperm traits, costly polyandry evolved to ensure female fertility, without requiring explicit inbreeding avoidance. Resulting sperm competition caused evolution of sperm traits and further mitigated the negative effect of inbreeding depression on female fertility. The evolving mating system fed back to decrease population‐wide homozygosity, and hence inbreeding. However, the net overall decrease was small due to compound effects on the variances in sex‐specific reproductive success and paternity skew. Purging of deleterious mutations did not eliminate inbreeding depression in sperm traits or hence selection for polyandry. Overall, our model illustrates that polyandry evolution, both directly and through sperm competition, might facilitate evolutionary rescue for populations experiencing sudden increases in inbreeding.

2010-01-01

Studies suggest that deficits in social problem-solving may be associated with increased risk of depression and suicidality in children and adolescents. It is unclear, however, which specific dimensions of social problem-solving are related to depression and suicidality among youth. Moreover, rational problem-solving strategies and problem-solving motivation may moderate or predict change in depression and suicidality among children and adolescents receiving treatment. The effect of social problem-solving on acute treatment outcomes were explored in a randomized controlled trial of 439 clinically depressed adolescents enrolled in the Treatment for Adolescents with Depression Study (TADS). Measures included the Children's Depression Rating Scale-Revised (CDRS-R), the Suicidal Ideation Questionnaire--Grades 7-9 (SIQ-Jr), and the Social Problem-Solving Inventory-Revised (SPSI-R). A random coefficients regression model was conducted to examine main and interaction effects of treatment and SPSI-R subscale scores on outcomes during the 12-week acute treatment stage. Negative problem orientation, positive problem orientation, and avoidant problem-solving style were non-specific predictors of depression severity. In terms of suicidality, avoidant problem-solving style and impulsiveness/carelessness style were predictors, whereas negative problem orientation and positive problem orientation were moderators of treatment outcome. Implications of these findings, limitations, and directions for future research are discussed. Copyright 2009 Elsevier Ltd. All rights reserved.

2016-01-01

The aim of the current study was to contribute to the development of a clinical profile of compulsive exercise in adolescents with Anorexia Nervosa (AN), by examining associations between compulsive exercise and eating and general psychopathology. A sample of 60 female adolescent inpatients with AN completed a self-report measure of compulsive exercise and a series of standardized self-report questionnaires assessing eating and general psychopathology. Higher levels of compulsive exercise were associated with increased levels of eating disorder psychopathology and anxiety. Specifically, the avoidance aspect (negatively reinforced) of compulsive exercise was associated with elevated scores on measures of eating disorder, anxiety, depression, and obsessive compulsiveness psychopathology, as well as lower self-esteem scores. The mood improvement value (positively reinforced) of compulsive exercise, however, did not reflect such trends. Compulsive exercise driven by avoidance of negative affect is associated with more severe psychological features in adolescent inpatients with AN. The current findings emphasize the need for research and clinical efforts in the development of treatments addressing avoidance of negative affect and compulsive exercise in adolescents with AN.

Locating anger in the hierarchical structure of affect: comment on Carver and Harmon-Jones (2009).

PubMed

Watson, David

2009-03-01

C. S. Carver and E. Harmon-Jones (2009) have presented considerable evidence to support their argument that "anger relates to an appetitive or approach motivational system, whereas anxiety relates to an aversive or avoidance motivational system" (p. 183). However, they have failed to take sufficient account of the extensive psychometric data indicating that anger is strongly related to anxiety (and other negative affects) and more weakly associated with the positive affects. Considering all of the available evidence, the most accurate conclusion is that anger shows both approach and avoidance properties. Moreover, viewed in the context of the hierarchical structure of affect, some evidence suggests that the nonspecific component of anger (i.e., its shared variance with the other negative affects) is primarily related to the aversive or avoidance motivational system, whereas its specific component (i.e., its unique qualities that distinguish it from other negative affects) has a stronger link to the appetitive or approach system. The author concludes by considering the broader implications of these data for affective structure. (c) 2009 APA, all rights reserved.

Attachment and exploration in adulthood: the mediating effect of social support.

2012-01-01

Research examining the relationship between adult attachment styles and exploratory behavior has shown that anxious and avoidant attachment styles are negatively related to exploration. However, little research has been conducted on the mediation process between adult attachment styles and exploration. Given that perceived social support has been shown to be the basis for secure attachment and may be related to exploration behavior, the current study examines whether perceived social support mediates the relationship between adult attachment and exploration. University students in Taiwan (N = 168) completed questionnaires that assessed attachment styles; perceived social support from their father, mother, and best friend; and their intellectual, social, and environmental exploration. Our results revealed that perceived social support mediates the relationship between avoidant attachment and exploration behavior.

Coping with perceived weight discrimination: testing a theoretical model for examining the relationship between perceived weight discrimination and depressive symptoms in a representative sample of individuals with obesity.

2016-12-01

The association between obesity and perceived weight discrimination has been investigated in several studies. Although there is evidence that perceived weight discrimination is associated with negative outcomes on psychological well-being, there is a lack of research examining possible buffering effects of coping strategies in dealing with experiences of weight discrimination. The present study aims to fill that gap. We examined the relationship between perceived weight discrimination and depressive symptoms and tested whether problem-solving strategies and/or avoidant coping strategies mediated this effect. Using structural equation modeling, we analyzed representative cross-sectional data of n=484 German-speaking individuals with obesity (BMI⩾30 kg m -2 ), aged 18 years and older. Results revealed a direct effect of perceived weight discrimination on depressive symptoms. Further, the data supported a mediational linkage for avoidant coping strategies, not for problem-solving strategies. Higher scores of perceived weight discrimination experiences were associated with both coping strategies, but only avoidant coping strategies were positively linked to more symptoms of depression. Perceived weight discrimination was associated with increased depressive symptoms both directly and indirectly through situational coping strategies. Avoidant coping has the potential to exacerbate depressive symptoms, whereas problem-solving strategies were ineffective in dealing with experiences of weight discrimination. We emphasize the importance of coping strategies in dealing with experiences of weight discrimination and the need to distinguish between using a strategy and benefiting from it without detriment.

Effect of Flumethrin on Survival and Olfactory Learning in Honeybees

2013-01-01

Flumethrin has been widely used as an acaricide for the control of Varroa mites in commercial honeybee keeping throughout the world for many years. Here we test the mortality of the Asian honeybee Apis cerana cerana after treatment with flumethrin. We also ask (1) how bees react to the odor of flumethrin, (2) whether its odor induces an innate avoidance response, (3) whether its taste transmits an aversive reinforcing component in olfactory learning, and (4) whether its odor or taste can be associated with reward in classical conditioning. Our results show that flumethrin has a negative effect on Apis ceranàs lifespan, induces an innate avoidance response, acts as a punishing reinforcer in olfactory learning, and interferes with the association of an appetitive conditioned stimulus. Furthermore flumethrin uptake within the colony reduces olfactory learning over an extended period of time. PMID:23785490

This study examined the mechanism by which stressors, dissatisfaction with family, perceived control, social support, and coping were related to psychological distress in a sample of HIV-positive African American mothers. Additional analyses explored whether women who had a history of a drug abuse or dependence diagnosis differed either on levels of the study variables or the model pathways. The results indicated that HIV-positive African American mothers who had higher levels of stressors perceived their stressors as a whole to be less controllable. Coping resources, available social support and perceived control, were positively associated with active coping and negatively associated with psychological distress. Avoidant coping was the most important predictor of psychological distress. Furthermore, the effect of avoidant coping on psychological distress was stronger for mothers with a history of drug diagnosis. The implications of these findings for targeting interventions are discussed.

Experiential Avoidance Mediates the Association between Emotion Regulation Abilities and Loneliness.

2016-01-01

Experiential avoidance (EA) involves the unwillingness to remain in contact with aversive experiences such as painful feelings, thoughts, and emotions. EA is often associated with the development and maintenance of emotional problems. Since loneliness is characterized by negative emotions such as sadness and pessimism, which is often linked to emotional problems, this study aims to test the mediating effects of EA on the relationship between emotion regulation abilities (ERA) and loneliness in a sample of Chinese adults. Five hundred undergraduates completed questionnaires measuring EA (Acceptance and Action Questionnaire; AAQ-Ⅱ), ERA (Failure-relate action orientation; Action Control Scale, ACS-90) and loneliness (UCLA Loneliness Scale). Structural equation modeling showed that EA fully-mediated the relationship between ERA and loneliness. The findings suggest EA is a key mechanism in explaining why people with high ERA are prone to feeling lower levels of loneliness. In particular, these findings have important implications for designing effective psychological interventions for loneliness.

A meta-analysis of fear-avoidance and pain intensity: The paradox of chronic pain.

PubMed

Kroska, Emily B

2016-10-01

The fear-avoidance model of chronic pain has established avoidance as a predictor of negative outcomes in chronic pain patients. Avoidance, or deliberate attempts to suppress or prevent unwanted experiences (e.g., pain), has been studied extensively, with multiple reviews implicating this behavior as a predictor of disability, physical disuse, and depression. Despite hundreds of studies examining the associations between different components of this model (i.e., catastrophizing, fear, avoidance, depression), the association between fear-avoidance and pain intensity has remained unclear. The present study seeks to clarify this association across samples. The present analyses synthesize the literature (articles from PsycInfo, PubMed, and ProQuest) to determine if fear-avoidance and pain intensity are consistently correlated across studies, samples, and measures. Eligible studies measured pain intensity and fear-avoidance cross-sectionally in chronic pain patients. The search resulted in 118 studies eligible for inclusion. A random-effects model was used to estimate the weighted mean effect size. Comprehensive Meta-Analysis software was used for all analyses. Moderation analyses elucidate the variables that affect the strength of this association. Meta-regression and meta-ANOVA analyses were conducted to examine moderating variables. Moderator variables include demographic characteristics, pain characteristics, study characteristics, and national cultural characteristics (using Hofstede's cultural dimensions). Publication bias was examined using the funnel plot and the p-curve. Results indicate a small-to-moderate positive association between fear-avoidance and pain intensity. The results were stable across characteristics of the sample, including mean age, gender distribution, marital status, and duration of pain. Moderation analyses indicate that the measures utilized and cultural differences affect the strength of this association. Weaker effect sizes were observed for studies that utilized measures of experiential avoidance when compared to studies that utilized pain-specific fear-avoidance measures. Studies that utilized multiple measures of fear-avoidance had stronger effect sizes than studies that utilized a single measure of fear-avoidance. Three of Hofstede's cultural dimensions moderated the association, including Power Distance Index, Individualism versus Collectivism, and Indulgence versus Restraint. The present meta-analysis synthesizes the results from studies examining the association between fear-avoidance and pain intensity among individuals with chronic pain. The positive association indicates that those with increased fear-avoidance have higher pain intensity, and those with higher pain intensity have increased fear-avoidance. Findings indicate that cultural differences and measurement instruments are important to consider in understanding the variables that affect this association. The significant cultural variations may indicate that it is important to consider the function of avoidance behavior in different cultures in an effort to better understand each patient's cultural beliefs, as well as how these beliefs are related to pain and associated coping strategies. The results from the current meta-analysis can be used to inform interventions for patients with chronic pain. In particular, those with more intense pain or increased fear-avoidance should be targeted for prevention and intervention work. Within the intervention itself, avoidance should be undermined and established as an ineffective strategy to manage pain in an effort to prevent disability, depression, and physical deconditioning.

ABSTRACT Background: Previous studies on the influence of different types of attachment on grief responses have yielded contradictory outcomes. Little research has been conducted to identify the psychological processes that moderate the relationship between attachment representations and patterns of grief in disaster-related grief. Objective: The present study examines the effects of different attachment types on the grief responses of parents bereaved by loss of a child in a ferry accident, along with the moderating role of coping strategies. Methods: Bereaved parents (n = 81) completed self-report questionnaires evaluating attachment, coping strategies, complicated grief, and shame/guilt. We performed correlational analyses to examine the associations among variables. We also conducted hierarchical regression analyses and simple slope analyses to examine the moderation effects of coping strategies. Results: Anxious attachment was associated with severe shame/guilt, and avoidant attachment correlated with complicated grief. Anxious attachment was positively associated with all types of coping strategies, and avoidant attachment was negatively related to problem- and emotion-focused coping. The use of problem-focused coping strategies was a significant moderator of the relationship between the avoidant attachment dimension and shame/guilt. Avoidant attachment had a significant effect on shame/guilt in groups with a high level of problem-focused coping. In contrast, none of the coping strategies significantly moderated the relationship between anxious attachment and grief response. Conclusions: The results suggest that people with highly avoidant attachment might be overwhelmed by shame and guilt when they try to use problem-focused coping strategies. This finding suggests that grief interventions should be organized with consideration of individual differences in attachment representations. PMID:29372009

It depends: Approach and avoidance reactions to emotional expressions are influenced by the contrast emotions presented in the task.

PubMed

Paulus, Andrea; Wentura, Dirk

2016-02-01

Studies examining approach and avoidance reactions to emotional expressions have yielded conflicting results. For example, expressions of anger have been reported to elicit approach reactions in some studies but avoidance reactions in others. Nonetheless, the results were often explained by the same general underlying process, namely the influence that the social message signaled by the expression has on motivational responses. It is therefore unclear which reaction is triggered by which emotional expression, and which underlying process is responsible for these reactions. In order to address this issue, we examined the role of a potential moderator on approach and avoidance reactions to emotional expressions, namely the contrast emotion used in the task. We believe that different approach and avoidance reactions occur depending on the congruency or incongruency of the evaluation of the 2 emotions presented in the task. The results from a series of experiments supported these assumptions: Negative emotional expressions (anger, fear, sadness) elicited avoidance reactions if contrasted with expressions of happiness. However, if contrasted with a different negative emotional expression, anger and sadness triggered approach reactions and fear activated avoidance reactions. Importantly, these results also emerged if the emotional expression was not task-relevant. We propose that approach and avoidance reactions to emotional expressions are triggered by their evaluation if the 2 emotions presented in a task differ in evaluative connotation. If they have the same evaluative connotation, however, reactions are determined by their social message. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Worry and Generalized Anxiety Disorder: A Review and Theoretical Synthesis of Evidence on Nature, Etiology, Mechanisms, and Treatment

2016-01-01

Generalized anxiety disorder (GAD) is associated with substantial personal and societal cost yet is the least successfully treated of the anxiety disorders. In this review, research on clinical features, boundary issues, and naturalistic course, as well as risk factors and maintaining mechanisms (cognitive, biological, neural, interpersonal, and developmental), are presented. A synthesis of these data points to a central role of emotional hyperreactivity, sensitivity to contrasting emotions, and dysfunctional attempts to cope with strong emotional shifts via worry. Consistent with the Contrast Avoidance model, evidence shows that worry evokes and sustains negative affect, thereby precluding sharp increases in negative emotion. We also review current treatment paradigms and suggest how the Contrast Avoidance model may help to target key fears and avoidance tendencies that serve to maintain pathology in GAD. PMID:23537486

Attachment-related strategies during thought suppression: ironic rebounds and vulnerable self-representations.

2004-12-01

The authors conducted 2 studies of attachment-related variations in thought suppression. Participants were asked, or not asked, to suppress thoughts about a relationship breakup and then to perform a Stroop task under high or low cognitive load. The dependent variables were the rebound, of previously suppressed separation-related thoughts (Study 1) and the accessibility of self-traits (Study 2). Under low cognitive load, avoidant individuals did not show any rebound of separation-related thoughts and activated positive self-representations. Under high cognitive load, avoidant participants failed to suppress thoughts of separation and were more likely to activate negative self-representations. Attachment anxiety was associated with high activation of negative self-representations and unremitting separation-related thoughts. The results are discussed in terms of the hidden vulnerabilities of avoidant individuals. ((c) 2004 APA, all rights reserved).

2011-04-01

This study assessed impact of Alzheimer's patients' aggressive behavior (AD aggression) on caregiver coping strategies (task-, emotion-, and avoidance-focused) and caregiver resilience, and examined whether coping strategy moderated the AD aggression-caregiver resilience relationship. Informal caregivers across Louisiana (N = 419) completed surveys with measures of demographics, AD aggression, caregiver coping strategies, and caregiver resilience. Task-focused coping positively related to resilience. Aggression negatively predicted caregiver resilience. Emotion- and avoidance-focused coping strategies separately interacted with aggression and increased its negative relationship to caregiver resilience. Task-focused coping showed no moderation. Implications for social work professionals are discussed.

The Impact of Experiential Avoidance on the Inference of Characters' Emotions: Evidence for an Emotional Processing Bias.

PubMed

Pickett, Scott M; Kurby, Christopher A

2010-12-01

Experiential avoidance is a functional class of maladaptive strategies that contribute to the development and maintenance of psychopathology. Although previous research has demonstrated group differences in the interpretation of aversive stimuli, there is limited work on the influence of experiential avoidance during the online processing of emotion. An experimental design investigated the influence of self-reported experiential avoidance during emotion processing by assessing emotion inferences during the comprehension of narratives that imply different emotions. Results suggest that experiential avoidance is partially characterized by an emotional information processing bias. Specifically, individuals reporting higher experiential avoidance scores exhibited a bias towards activating negative emotion inferences, whereas individuals reporting lower experiential avoidance scores exhibited a bias towards activating positive emotion inferences. Minimal emotional inference was observed for the non-bias affective valence. Findings are discussed in terms of the implications of experiential avoidance as a cognitive vulnerability for psychopathology.

Evidence for negative feature guidance in visual search is explained by spatial recoding.

PubMed

Beck, Valerie M; Hollingworth, Andrew

2015-10-01

Theories of attention and visual search explain how attention is guided toward objects with known target features. But can attention be directed away from objects with a feature known to be associated only with distractors? Most studies have found that the demand to maintain the to-be-avoided feature in visual working memory biases attention toward matching objects rather than away from them. In contrast, Arita, Carlisle, and Woodman (2012) claimed that attention can be configured to selectively avoid objects that match a cued distractor color, and they reported evidence that this type of negative cue generates search benefits. However, the colors of the search array items in Arita et al. (2012) were segregated by hemifield (e.g., blue items on the left, red on the right), which allowed for a strategy of translating the feature-cue information into a simple spatial template (e.g., avoid right, or attend left). In the present study, we replicated the negative cue benefit using the Arita et al. (2012), method (albeit within a subset of participants who reliably used the color cues to guide attention). Then, we eliminated the benefit by using search arrays that could not be grouped by hemifield. Our results suggest that feature-guided avoidance is implemented only indirectly, in this case by translating feature-cue information into a spatial template. (c) 2015 APA, all rights reserved).

Self-subjugation among women: exposure to sexist ideology, self-objectification, and the protective function of the need to avoid closure.

PubMed

Calogero, Rachel M; Jost, John T

2011-02-01

Despite extensive evidence confirming the negative consequences of self-objectification, direct experimental evidence concerning its environmental antecedents is scarce. Incidental exposure to sexist cues was employed in 3 experiments to investigate its effect on self-objectification variables. Consistent with system justification theory, exposure to benevolent and complementary forms of sexism, but not hostile or no sexism, increased state self-objectification, self-surveillance, and body shame among women but not men in Experiment 1. In Experiment 2, we replicated these effects and demonstrated that they are specific to self-objectification and not due to a more general self-focus. In addition, following exposure to benevolent sexism only, women planned more future behaviors pertaining to appearance management than did men; this effect was mediated by self-surveillance and body shame. Experiment 3 revealed that the need to avoid closure might afford women some protection against self-objectification in the context of sexist ideology.

The present experiment was devised to test a prediction of the Opponent-Process Theory of drug action. This theory presumes that the initial affective experience of a subject treated with cocaine would be diametrically different immediately after administration compared to some point later in time when the positive impact of the drug had subsided. A conditioned place-preference procedure was employed in which a novel environment was paired with the effects of cocaine either immediately after, 5 min after, or 15 min after an intravenous injection of 0.75 mg/kg cocaine. It was hypothesized that animals would come to prefer environments associated with the immediate positive effects of cocaine and avoid environments associated with the drug's subsequent negative effects. The results confirmed this hypothesis. While the 0-min delay and 5-min delay groups exhibited conditioned preferences for the cocaine-paired environment, the 15-min delay group came to avoid the side of the preference apparatus paired with cocaine. These data, therefore, serve as additional support for an Opponent-Process account of cocaine's actions.

Theoretical Basis of the Test-Negative Study Design for Assessment of Influenza Vaccine Effectiveness.

2016-09-01

Influenza viruses undergo frequent antigenic changes. As a result, the viruses circulating change within and between seasons, and the composition of the influenza vaccine is updated annually. Thus, estimation of the vaccine's effectiveness is not constant across seasons. In order to provide annual estimates of the influenza vaccine's effectiveness, health departments have increasingly adopted the "test-negative design," using enhanced data from routine surveillance systems. In this design, patients presenting to participating general practitioners with influenza-like illness are swabbed for laboratory testing; those testing positive for influenza virus are defined as cases, and those testing negative form the comparison group. Data on patients' vaccination histories and confounder profiles are also collected. Vaccine effectiveness is estimated from the odds ratio comparing the odds of testing positive for influenza among vaccinated patients and unvaccinated patients, adjusting for confounders. The test-negative design is purported to reduce bias associated with confounding by health-care-seeking behavior and misclassification of cases. In this paper, we use directed acyclic graphs to characterize potential biases in studies of influenza vaccine effectiveness using the test-negative design. We show how studies using this design can avoid or minimize bias and where bias may be introduced with particular study design variations. © The Author 2016.

[Will publication of quality indicators in the health service improve the quality? International experiences and Danish perspectives].

PubMed

Endahl, Lars A; Utzon, Jan

2002-09-16

It is well known that publication of hospital quality indicators may lead to improving of treatments. But the publication can also have some negative side effects: Focus may shift to the evaluated areas at the expense of non-evaluated areas. The most ill patients may be sorted out and high risk patients may be transferred to other hospitals or discharged in order to avoid their dying during hospitalisation and improve statistics. Overestimation of patient risk in order to improve relative treatment outcome. Increasing flow of patients to hospitals with high scores on quality indicators may cause imbalance between activities and budgets and hence longer waiting times and reduced quality of treatment. Negative publicity due to low scores on quality indicators may lead to under-utilisation of hospital capacity, patient and staff insecurity and staff wastage. Thus, publication of quality indicators may improve quality within the health sector, but it is very important to recognise potential pitfalls and negative side effects.

Does being attractive always help? Positive and negative effects of attractiveness on social decision making.

PubMed

Agthe, Maria; Spörrle, Matthias; Maner, Jon K

2011-08-01

Previous studies of organizational decision making demonstrate an abundance of positive biases directed toward highly attractive individuals. The current research, in contrast, suggests that when the person being evaluated is of the same sex as the evaluator, attractiveness hurts, rather than helps. Three experiments assessing evaluations of potential job candidates (Studies 1 and 3) and university applicants (Study 2) demonstrated positive biases toward highly attractive other-sex targets but negative biases toward highly attractive same-sex targets. This pattern was mediated by variability in participants' desire to interact with versus avoid the target individual (Studies 1 and 2) and was moderated by participants' level of self-esteem (Study 3); the derogation of attractive same-sex targets was not observed among people with high self-esteem. Findings demonstrate an important exception to the positive effects of attractiveness in organizational settings and suggest that negative responses to attractive same-sex targets stem from perceptions of self-threat.

Chloroplast avoidance movement as a sensitive indicator of relative water content during leaf desiccation in the dark.

In the context of global climate change, drought is one of the major stress factors with negative effect on photosynthesis and plant productivity. Currently, chlorophyll fluorescence parameters are widely used as indicators of plant stress, mainly owing to the rapid, non-destructive and simple measurements this technique allows. However, these parameters have been shown to have limited sensitivity for the monitoring of water deficit as leaf desiccation has relatively small effect on photosystem II photochemistry. In this study, we found that blue light-induced increase in leaf transmittance reflecting chloroplast avoidance movement was much more sensitive to a decrease in relative water content (RWC) than chlorophyll fluorescence parameters in dark-desiccating leaves of tobacco (Nicotiana tabacum L.) and barley (Hordeum vulgare L.). Whereas the inhibition of chloroplast avoidance movement was detectable in leaves even with a small RWC decrease, the chlorophyll fluorescence parameters (F V/F M, V J, Ф PSII, NPQ) changed markedly only when RWC dropped below 70 %. For this reason, we propose light-induced chloroplast avoidance movement as a sensitive indicator of the decrease in leaf RWC. As our measurement of chloroplast movement using collimated transmittance is simple and non-destructive, it may be more suitable in some cases for the detection of plant stresses including water deficit than the conventionally used chlorophyll fluorescence methods.

Relationships among symptom severity, coping styles, and quality of life in community-dwelling women with urinary incontinence: a multiple mediator model.

To investigate the relationships among symptom severity, coping styles, and quality of life (QOL) in community-dwelling women with urinary incontinence (UI). A total of 592 women with UI participated in this cross-sectional study. Bivariate Pearson's correlation was used to examine the correlations between symptom severity, coping styles, and QOL. Multivariate regression models and Sobel tests were used to test the mediating effect of coping styles. Additionally, a multiple mediator model was used to examine the mediating role of coping styles collectively. All regression models were adjusted for age, education, marital status, income, duration of UI, and type of UI. Participants tended to use avoidant and palliative coping styles and not use instrumental coping style. Avoidant and palliative coping styles were associated with poor QOL, and partially mediated the association between symptom severity and QOL. Nearly 73% of the adverse effect of symptom severity on QOL was mediated by avoidant and palliative coping styles. The use of avoidant and palliative coping styles was higher with more severe urine leakage, and QOL tended to be poorer. Coping styles should be addressed in UI management. It may be of particular value to look closely at negative coping styles and implement education and training of patients in improving their coping skills related to managing UI, which will in turn improve their QOL.

Why do fearful facial expressions elicit behavioral approach? Evidence from a combined approach-avoidance implicit association test.

PubMed

Hammer, Jennifer L; Marsh, Abigail A

2015-04-01

Despite communicating a "negative" emotion, fearful facial expressions predominantly elicit behavioral approach from perceivers. It has been hypothesized that this seemingly paradoxical effect may occur due to fearful expressions' resemblance to vulnerable, infantile faces. However, this hypothesis has not yet been tested. We used a combined approach-avoidance/implicit association test (IAT) to test this hypothesis. Participants completed an approach-avoidance lever task during which they responded to fearful and angry facial expressions as well as neutral infant and adult faces presented in an IAT format. Results demonstrated an implicit association between fearful facial expressions and infant faces and showed that both fearful expressions and infant faces primarily elicit behavioral approach. The dominance of approach responses to both fearful expressions and infant faces decreased as a function of psychopathic personality traits. Results suggest that the prosocial responses to fearful expressions observed in most individuals may stem from their associations with infantile faces.

Possible selves in patients with right- versus left-onset Parkinson's disease.

PubMed

Harris, Erica; McNamara, Patrick; Durso, Raymon

2017-03-01

Possible selves can be used to self-regulate and guide behavior towards what is desired to be achieved or avoided in life. Previous work suggests laterality effects exist within the brain regarding approach and avoidance systems to achieve self-regulation. A modified version of the possible selves task was administered to 45 patients with PD (22 right-onset and 23 left-onset) and 25 community dwelling control subjects (CS). Only 11.1% of patients exhibited balance among their hoped-for and feared possible selves versus 28% of CS. More right-onset patients used a promotion strategy whereas more left-onset patients used a prevention strategy. Patients with left-onset PD thought more about their feared selves, exhibiting reduced goal-directed behavior. Findings among the left-onset group indicate relative dependence of self-regulation on right-sided avoidance brain systems. This may point to an inability to move away from negative outcomes and to work towards rewarding outcomes, which could affect psychological health.

Attachment, attractiveness, and social interaction: a diary study.

PubMed

Tidwell, M C; Reis, H T; Shaver, P R

1996-10-01

To what extent are attachment styles manifested in natural social activity? A total of 125 participants categorized as possessing secure, avoidant, or anxious-ambivalent attachment styles kept structured social interaction diaries for 1 week. Several theoretically important findings emerged. First, compared with secure and anxious-ambivalent persons, avoidant persons reported lower levels of intimacy, enjoyment, promotive interaction, and positive emotions, and higher levels of negative emotions, primarily in opposite-sex interactions. Analyses indicated that avoidant persons may structure social activities in ways that minimize closeness. Second, secure people differentiated more clearly than either insecure group between romantic and other opposite-sex partners. Third, the subjective experiences of anxious-ambivalent persons were more variable than those of the other groups. Finally, the authors examined and rejected the possibility that attachment effects might be confounded with physical attractiveness. These findings suggest that feeling and behaviors that arise during spontaneous, everyday social activity may contribute to the maintenance of attachment styles in adulthood.

Evidence of hypoxic foraging forays by yellow perch (Perca flavescens) and potential consequences for prey consumption

Previous studies in a variety of ecosystems have shown that ecologically and economically important benthic and bentho-pelagic fishes avoid hypoxic (−1) habitats by moving vertically or horizontally to more oxygenated areas. While avoidance of hypoxic conditions generally leads to a complete shift away from preferred benthic prey, some individual fish continue to consume benthic prey items in spite of bottom hypoxia, suggesting complex habitat utilisation and foraging patterns. For example, Lake Erie yellow perch (Perca flavescens) continue to consume benthic prey, despite being displaced vertically and horizontally by hypolimnetic hypoxia. We hypothesised that hypolimnetic hypoxia can negatively affect yellow perch by altering their distribution and inducing energetically expensive foraging behaviour. To test this hypothesis, we used drifting hydroacoustics and trawl sampling to quantify water column distribution, sub-daily vertical movement and foraging behaviour of yellow perch within hypoxic and normoxic habitats of Lake Erie’s central basin during August-September 2007. We also investigated the effects of rapid changes in ambient oxygen conditions on yellow perch consumption potential by exposing yellow perch to various static and fluctuating oxygen conditions in a controlled laboratory experiment. Our results indicate that, while yellow perch in general avoid hypoxic conditions, some individuals undertake foraging forays into hypoxic habitats where they experience greater fluctuations in abiotic conditions (pressure, temperature and oxygen concentration) than at normoxic sites. However, laboratory results suggest short-term exposure to low oxygen conditions did not negatively impact consumption potential of yellow perch. Detailed understanding of sub-daily individual behaviours may be crucial for determining interactive individual- and ecosystem-level effects of stressors such as hypoxia.

Effect of framing on adolescents' decision making.

PubMed

Chien, Y C; Lin, C; Worthley, J

1996-12-01

92 young adolescents were tested using Tversky and Kahneman's (1981) decision problems for framing effects. A notable number of young adolescents tested were not influenced by the context of the decision problems, thus they selected the same response option for positively and negatively framed problems. Parallel information was not available in Tversky and Kahneman's study for adults because they used a between-subjects design. However, for present adolescents who selected different response options for different framing problems, the response pattern exhibited by them resembled the general pattern exhibited by the adults tested in Tversky and Kahneman's study-negative frames led them to accept risk to avoid certain loss; positive frames prevented them from risking what they were certain to gain. Boys and girls were similar in their susceptibility to framing effects as were honors students in mathematics as compared to nonhonors students. Although the positive vs negative framing only influenced some of the young adolescents tested in this study, because the influence was consistent, researchers and educators interested in adolescents' decisions involving risky choices might use framing principles to design and assess cognitive interventions for high-risk behaviors among young adolescents.

Activating attachment representations during memory retrieval modulates intrusive traumatic memories.

PubMed

Bryant, Richard A; Chan, Iris

2017-10-01

Although priming mental representations of attachment security reduces arousal, research has not examined the effect of attachment on the retrieval of emotionally arousing memories. This study investigated the effect of priming attachment security on the retrieval of emotional memories. Seventy-five participants viewed negative and neutral images, and two days later received either an attachment prime or a control prime immediately prior to free recall of the images. Two days later, participants reported how frequently they experienced intrusions of the negative images. The attachment group had less distress, and reported fewer subsequent intrusions than the control group. Attachment style moderated these effects such that individuals with an avoidant attachment style were not impacted by the attachment prime. These findings suggest that priming attachment security decreases distress during memory reactivation, and this may reduce subsequent intrusive memories. Copyright © 2017 Elsevier Inc.

Influence of perceived motivational climate on achievement goals in physical education: a structural equation mixture modeling analysis.

PubMed

Wang, J C; Liu, W C; Chatzisarantis, N L; Lim, C B

2010-06-01

The purpose of the current study was to examine the influence of perceived motivational climate on achievement goals in physical education using a structural equation mixture modeling (SEMM) analysis. Within one analysis, we identified groups of students with homogenous profiles in perceptions of motivational climate and examined the relationships between motivational climate, 2 x 2 achievement goals, and affect, concurrently. The findings of the current study showed that there were at least two distinct groups of students with differing perceptions of motivational climate: one group of students had much higher perceptions in both climates compared with the other group. Regardless of their grouping, the relationships between motivational climate, achievement goals, and enjoyment seemed to be invariant. Mastery climate predicted the adoption of mastery-approach and mastery-avoidance goals; performance climate was related to performance-approach and performance-avoidance goals. Mastery-approach goal had a strong positive effect while performance-avoidance had a small negative effect on enjoyment. Overall, it was concluded that only perception of a mastery motivational climate in physical education may foster intrinsic interest in physical education through adoption of mastery-approach goals.

Higher-Order Corrections to Earthʼs Ionosphere Shocks

2017-01-01

Nonlinear shock wave structures in unmagnetized collisionless viscous plasmas composed fluid of positive (negative) ions and nonthermally electron distribution are examined. For ion shock formation, a reductive perturbation technique applied to derive Burgers equation for lowest-order potential. As the shock amplitude decreasing or enlarging, its steepness and velocity deviate from Burger equation. Burgers type equation with higher order dissipation must be obtained to avoid this deviation. Solution for the compined two equations has been derived using renormalization analysis. Effects of higher-order, positive- negative mass ratio Q, electron nonthermal parameter δ and kinematic viscosities coefficient of positive (negative) ions {η }1 and {η }2 on the electrostatic shocks in Earth’s ionosphere are also argued.

Effects of Salinity on the Habitat Selection and Growth Performance of Mediterranean Flathead Grey Mullet Mugil cephalus (Osteichthyes, Mugilidae)

NASA Astrophysics Data System (ADS)

Cardona, L.

2000-05-01

Flathead grey mullet (Mugil cephalus L. 1758) are commonly found in tropical and temperate estuaries. In spite of their ecological and economical importance, little is known about the effects of salinity on growth performance and habitat selection. Laboratory experiments revealed that the metabolic rate of young specimens was negatively affected by high salinity levels and that an improved growth performance was achieved in fresh water and oligohaline water. A stratified study on microhabitat use, carried out on the island of Minorca (Balearic archipelago), demonstrated that juvenile specimens, shorter than 200 mm (total length), concentrated all year round in fresh water or oligohaline sites. Mesohaline areas were usually avoided, except in summer. Immature fish, with a total length between 201 and 300 mm, show a similar pattern although in some seasons avoided freshwater sites. The habitat selection pattern of adults, i.e., fish longer than 301 mm, changed seasonally due to their offshore migration during the spawning season (from late summer to early winter). However, they usually showed a greater preference for polyhaline areas and strongly avoided freshwater sites. Euhaline areas were also avoided in autumn and summer. These results suggest that the young of this species are highly dependent on areas of low salinity and any factor which reduces the availability of such areas will, in turn, affect their fishery. Adults depend on polyhaline areas, although the avoidance of freshwater areas might be due to their shallowness. The situation might be different in some areas of the Indo-Pacific. These differences are discussed.

2005-10-01

A growing body of research supports cooperative learning as an effective teaching strategy. A specific cooperative learning strategy, Team-based Learning, was applied to a convenience sample of four undergraduate sophomore-level motor behavior courses over four semesters from Fall 2002 to Spring 2004 to examine whether this strategy would affect students' learning styles. The data from the Grasha-Reichmann Student Learning Style Scales indicated that this teaching strategy was associated with a significant decrease in the negative Avoidant and Dependent learning styles and an improvement in the positive Participant learning style.

Effects of Adult Romantic Attachment and Social Support on Resilience and Depression in Individuals with Spinal Cord Injuries

Dodd, Zane; Warren, Ann Marie; Riggs, Shelley; Clark, Mike

2015-01-01

Background: Spinal cord injury (SCI) can cause psychological consequences that negatively affect quality of life. It is increasingly recognized that factors such as resilience and social support may produce a buffering effect and are associated with improved health outcomes. However the influence of adult attachment style on an individual’s ability to utilize social support after SCI has not been examined. Objective: The purpose of this study was to examine relationships between adult romantic attachment perceived social support depression and resilience in individuals with SCI. In addition we evaluated potential mediating effects of social support and adult attachment on resilience and depression. Methods: Participants included 106 adults with SCI undergoing inpatient rehabilitation. Individuals completed measures of adult attachment (avoidance and anxiety) social support resilience and depression. Path analysis was performed to assess for presence of mediation effects. Results: When accounting for the smaller sample size support was found for the model (comparative fit index = .927 chi square = 7.86 P = .01 β = -0.25 standard error [SE] = -2.93 P < .05). The mediating effect of social support on the association between attachment avoidance and resilience was the only hypothesized mediating effect found to be significant (β = -0.25 SE = -2.93 P < .05). Conclusion: Results suggest that individuals with SCI with higher levels of attachment avoidance have lower perceived social support which relates to lower perceived resilience. Assessing attachment patterns during inpatient rehabilitation may allow therapists to intervene to provide greater support. PMID:26364285

The Dyadic Construction of Romantic Conflict Recovery Sabotage

PubMed Central

Haydon, Katherine C.; Jonestrask, Cassandra; Guhn-Knight, Haley; Salvatore, Jessica E.

2017-01-01

This longitudinal study of 100 couples assessed individual and dyadic processes associated with romantic conflict recovery, or how couples behave in the moments following conflict. Couples completed measures of attachment anxiety and avoidance; a conflict discussion during which affect, behavior, and conflict resolution were coded; a cool-down discussion during which post-conflict behavior was coded; and measures of relationship satisfaction and stability one year later. Recovery sabotage (negative behavior and perseveration on conflict in the moments following conflict) was associated with high attachment anxiety and low avoidance. Recovery sabotage was unrelated to affect expressed during conflict and was instead tied to whether partners aired or suppressed grievances. Consistent with the demand-withdraw conflict pattern, recovery sabotage was associated with lower actor conflict avoidance but higher partner conflict avoidance. These effects were independent of conflict resolution, which was not significantly associated with recovery sabotage when other features of conflict were controlled. Recovery sabotage and conflict resolution also differentially predicted satisfaction and stability one year later. Findings suggest recovery sabotage is a distinct, developmentally organized relationship process tied to attachment history and behavioral, rather than affective, transactions between partners during conflict.

Categorization-based stranger avoidance does not explain the uncanny valley effect.

PubMed

MacDorman, Karl F; Chattopadhyay, Debaleena

2017-04-01

The uncanny valley hypothesis predicts that an entity appearing almost human risks eliciting cold, eerie feelings in viewers. Categorization-based stranger avoidance theory identifies the cause of this feeling as categorizing the entity into a novel category. This explanation is doubtful because stranger is not a novel category in adults; infants do not avoid strangers while the category stranger remains novel; infants old enough to fear strangers prefer photographs of strangers to those more closely resembling a familiar person; and the uncanny valley's characteristic eeriness is seldom felt when meeting strangers. We repeated our original experiment with a more realistic 3D computer model and found no support for categorization-based stranger avoidance theory. By contrast, realism inconsistency theory explains cold, eerie feelings elicited by transitions between instances of two different, mutually exclusive categories, given that at least one category is anthropomorphic: Cold, eerie feelings are caused by prediction error from perceiving some features as features of the first category and other features as features of the second category. In principle, realism inconsistency theory can explain not only negative evaluations of transitions between real and computer modeled humans but also between different vertebrate species.

Plasmids as stochastic model systems

NASA Astrophysics Data System (ADS)

Paulsson, Johan

2003-05-01

Plasmids are self-replicating gene clusters present in on average 2-100 copies per bacterial cell. To reduce random fluctuations and thereby avoid extinction, they ubiquitously autoregulate their own synthesis using negative feedback loops. Here I use van Kampen's Ω-expansion for a two-dimensional model of negative feedback including plasmids and ther replication inhibitors. This analytically summarizes the standard perspective on replication control -- including the effects of sensitivity amplification, exponential time-delays and noisy signaling. I further review the two most common molecular sensitivity mechanisms: multistep control and cooperativity. Finally, I discuss more controversial sensitivity schemes, such as noise-enhanced sensitivity, the exploitation of small-number combinatorics and double-layered feedback loops to suppress noise in disordered environments.

Extinction of avoidance behavior by safety learning depends on endocannabinoid signaling in the hippocampus.

2017-07-01

The development of exaggerated avoidance behavior is largely responsible for the decreased quality of life in patients suffering from anxiety disorders. Studies using animal models have contributed to the understanding of the neural mechanisms underlying the acquisition of avoidance responses. However, much less is known about its extinction. Here we provide evidence in mice that learning about the safety of an environment (i.e., safety learning) rather than repeated execution of the avoided response in absence of negative consequences (i.e., response extinction) allowed the animals to overcome their avoidance behavior in a step-down avoidance task. This process was context-dependent and could be blocked by pharmacological (3 mg/kg, s.c.; SR141716) or genetic (lack of cannabinoid CB1 receptors in neurons expressing dopamine D1 receptors) inactivation of CB1 receptors. In turn, the endocannabinoid reuptake inhibitor AM404 (3 mg/kg, i.p.) facilitated safety learning in a CB1-dependent manner and attenuated the relapse of avoidance behavior 28 days after conditioning. Safety learning crucially depended on endocannabinoid signaling at level of the hippocampus, since intrahippocampal SR141716 treatment impaired, whereas AM404 facilitated safety learning. Other than AM404, treatment with diazepam (1 mg/kg, i.p.) impaired safety learning. Drug effects on behavior were directly mirrored by drug effects on evoked activity propagation through the hippocampal trisynaptic circuit in brain slices: As revealed by voltage-sensitive dye imaging, diazepam impaired whereas AM404 facilitated activity propagation to CA1 in a CB1-dependent manner. In line with this, systemic AM404 enhanced safety learning-induced expression of Egr1 at level of CA1. Together, our data render it likely that AM404 promotes safety learning by enhancing information flow through the trisynaptic circuit to CA1. Copyright © 2017 Elsevier Ltd. All rights reserved.

Pain-catastrophizing and fear-avoidance beliefs as mediators between post-traumatic stress symptoms and pain following whiplash injury - A prospective cohort study.

PubMed

Andersen, T E; Karstoft, K-I; Brink, O; Elklit, A

2016-09-01

Knowledge about the course of recovery after whiplash injury is important. Most valuable is identification of prognostic factors that may be reversed by intervention. The mutual maintenance model outlines how post-traumatic stress symptoms (PTSS) and pain may be mutually maintained by attention bias, fear, negative affect and avoidance behaviours. In a similar vein, the fear-avoidance model describes how pain-catastrophizing (PCS), fear-avoidance beliefs (FA) and depression may result in persistent pain. These mechanisms still need to be investigated longitudinally in a whiplash cohort. A longitudinal cohort design was used to assess patients for pain intensity and psychological distress after whiplash injury. Consecutive patients were all contacted within 3 weeks after their whiplash injury (n = 198). Follow-up questionnaires were sent 3 and 6 months post-injury. Latent Growth Mixture Modelling was used to identify distinct trajectories of recovery from pain. Five distinct trajectories were identified. Six months post-injury, 64.6% could be classified as recovered and 35.4% as non-recovered. The non-recovered (the medium stable, high stable and very high stable trajectories) displayed significantly higher levels of PTSS, PCS, FA and depression at all time points compared to the recovered trajectories. Importantly, PCS and FA mediated the effect of PTSS on pain intensity. The present study adds important knowledge about the development of psychological distress and pain after whiplash injury. The finding, that PCS and FA mediated the effect of PTSS on pain intensity is a novel finding with important implications for prevention and management of whiplash-associated disorders. WHAT DOES THIS STUDY ADD?: The study confirms the mechanisms as outlined in the fear-avoidance model and the mutual maintenance model. The study adds important knowledge of pain-catastrophizing and fear-avoidance beliefs as mediating mechanisms in the effect of post-traumatic stress on pain intensity. Hence, cognitive behavioural techniques targeting avoidance behaviour and catastrophizing may be beneficial preventing the development of chronic pain. © 2016 European Pain Federation - EFIC®

Contextual modulation of value signals in reward and punishment learning

PubMed Central

Palminteri, Stefano; Khamassi, Mehdi; Joffily, Mateus; Coricelli, Giorgio

2015-01-01

Compared with reward seeking, punishment avoidance learning is less clearly understood at both the computational and neurobiological levels. Here we demonstrate, using computational modelling and fMRI in humans, that learning option values in a relative—context-dependent—scale offers a simple computational solution for avoidance learning. The context (or state) value sets the reference point to which an outcome should be compared before updating the option value. Consequently, in contexts with an overall negative expected value, successful punishment avoidance acquires a positive value, thus reinforcing the response. As revealed by post-learning assessment of options values, contextual influences are enhanced when subjects are informed about the result of the forgone alternative (counterfactual information). This is mirrored at the neural level by a shift in negative outcome encoding from the anterior insula to the ventral striatum, suggesting that value contextualization also limits the need to mobilize an opponent punishment learning system.

Esnaashari, Fatemeh; Kargar, Flor Rezaei

2018-06-01

The aim of this research was to determine the relation between death attitude and distress tolerance and aggression and anger. For this, 135 subjects among 7,535 professional and specialist members of the Iran National Library were selected using convenience sampling method. They replied to Death Attitudes Profile-Revised, distress tolerance questionnaire, and aggression questionnaire. The results showed that the attitudes of approach acceptance, neutral acceptance, and escape acceptance had positive relation to distress tolerance and negative relation to aggression and anger while the attitudes of fear of death and death avoidance had negative relation to distress tolerance and positive relation to aggression and anger. Furthermore, all death attitudes predicted distress tolerance. But only the attitudes of approach acceptance, escape acceptance, fear of death, and death avoidance predicted aggression, and only approach acceptance, neutral acceptance, fear of death, and death avoidance predicted anger.

The relations of motivational traits with workplace deviance.

PubMed

Diefendorff, James M; Mehta, Kajal

2007-07-01

The authors developed and tested new theoretical relations between approach and avoidance motivational traits and deviant work behaviors. Approach motivation was divided into 3 traits: personal mastery (i.e., desire to achieve), competitive excellence (i.e., desire to perform better than others), and behavioral activation system (BAS) sensitivity (i.e., responsiveness to rewards). Avoidance motivation, which reflects one's sensitivity to negative stimuli and the desire to escape such stimuli, was conceptualized as a unitary construct. Using structural equation modeling, the authors examined the relations of these 4 motivational traits with interpersonal and organizational deviance in a sample of primarily part-time employees. For the approach motivation traits, results showed that personal mastery was negatively related to interpersonal and organizational deviance, BAS sensitivity was positively related to interpersonal and organizational deviance, and competitive excellence was unrelated to both types of workplace deviance. Finally, avoidance motivation was positively related to organizational deviance and interacted with organizational constraints to predict interpersonal deviance.

Here we demonstrate, using computational modelling and fMRI in humans, that learning option values in a relative--context-dependent--scale offers a simple computational solution for avoidance learning. The context (or state) value sets the reference point to which an outcome should be compared before updating the option value. Consequently, in contexts with an overall negative expected value, successful punishment avoidance acquires a positive value, thus reinforcing the response. As revealed by post-learning assessment of options values, contextual influences are enhanced when subjects are informed about the result of the forgone alternative (counterfactual information). This is mirrored at the neural level by a shift in negative outcome encoding from the anterior insula to the ventral striatum, suggesting that value contextualization also limits the need to mobilize an opponent punishment learning system.

The present study investigated the effects of approach versus avoidance motivation on declarative learning. Human participants navigated a virtual reality version of the Morris water task, a classic spatial memory paradigm, adapted to permit the experimental manipulation of motivation during learning. During this task, participants were instructed to navigate to correct platforms while avoiding incorrect platforms. To manipulate motivational states participants were either rewarded for navigating to correct locations (approach) or punished for navigating to incorrect platforms (avoidance). Participants' skin conductance levels (SCLs) were recorded during navigation to investigate the role of physiological arousal in motivated learning. Behavioral results revealed that, overall, approach motivation enhanced and avoidance motivation impaired memory performance compared to nonmotivated spatial learning. This advantage was evident across several performance indices, including accuracy, learning rate, path length, and proximity to platform locations during probe trials. SCL analysis revealed three key findings. First, within subjects, arousal interacted with approach motivation, such that high arousal on a given trial was associated with performance deficits. In addition, across subjects, high arousal negated or reversed the benefits of approach motivation. Finally, low-performing, highly aroused participants showed SCL responses similar to those of avoidance-motivation participants, suggesting that for these individuals, opportunities for reward may evoke states of learning similar to those typically evoked by threats of punishment. These results provide a novel characterization of how approach and avoidance motivation influence declarative memory and indicate a critical and selective role for arousal in determining how reinforcement influences goal-oriented learning.

The reduction of avoidance behavior is a central target in the treatment of anxiety disorders, but it has rarely been studied how approach of fear-relevant stimuli may be initiated. In two studies, the impact of hypothetical monetary and symbolic social incentives on approach-avoidance behavior was examined. In Study 1, individuals high or low on fear of spiders (N = 84) could choose to approach a fear-relevant versus a neutral stimulus, which were equally rewarded. In a subsequent micro-intervention, approaching the fear-relevant stimulus was differentially rewarded either by monetary or social incentives. In Study 2 (N = 76), initial incentives for approach were discontinued to investigate the stability of approach. Hypothetical monetary and symbolic social incentives reduced or eliminated initial avoidance, even in highly fearful individuals. Approach resulted in a decrease of self-reported aversiveness towards the fear-relevant stimulus. However, even after successful approach, fearful individuals showed significant avoidance behavior when incentives for approach were discontinued. Future research should investigate the long-term effects of prolonged approach incentives on multiple levels of fear (e.g., self-report, behavioral, physiological). It should also be tested if such an intervention actually improves compliance with exposure based interventions. The present findings highlight that incentives are useful to initiate initial approach towards a feared stimulus. Although incentive-based approach may neither fully eliminate avoidance nor negative feelings towards the feared stimulus, such operant interventions may set the stage for more extensive extinction training.

Regulation of automatic approach and avoidance behavior requires affective and cognitive control, which are both influenced by a genetic variation in the gene encoding Monoamine Oxidase A (termed MAOA-uVNTR). The current study investigated MAOA genotype as a moderator of prefrontal cortical activation measured with functional near-infrared spectroscopy (fNIRS) in 37 healthy young adults during performance of the approach-avoidance task with positive and negative pictures. Carriers of the low- compared to the high-expressing genetic variant (MAOA-L vs. MAOA-H) showed increasing regulatory activity in the right dorsolateral prefrontal cortex (DLPFC) during incompatible conditions (approach negative, avoid positive). This might have been a compensatory mechanism for stronger emotional reactions as shown in previous studies and might have prevented any influence of incompatibility on behavior. In contrast, fewer errors but also lower activity in the right DLPFC during processing of negative compared to positive stimuli indicated MAOA-H carriers to have used other regulatory areas. This resulted in slower reaction times in incompatible conditions, but--in line with the known better cognitive regulation efficiency--allowed them to perform incompatible reactions without activating the DLPFC as the highest control instance. Carriers of one low- and one high-expressing allele lay as an intermediate group between the reactions of the low- and high-expressing groups. The relatively small sample size and restriction to fNIRS for assessment of cortical activity limit our findings. Nevertheless, these first results suggest monoam-inergic mechanisms to contribute to interindividual differences in the two basic behavioral principles of approach and avoidance and their neuronal correlates.

Objectives Erectile rehabilitation (ER) following radical prostatectomy (RP) is considered an essential component to help men regain erectile functioning; however many men have difficulty adhering to this type of a program. This qualitative study explored men's experience with ER, erectile dysfunction (ED), and ED treatments to inform a psychological intervention designed to help men adhere to ER post-RP. Methods Thirty men, one to three years post-RP, who took part in an ER program, participated in one of four focus groups. Thematic analysis was used to identify the primary themes. Results Average age was 59 (SD=7); mean time since surgery was 26 months (SD=6). Six primary themes emerged: 1) frustration with the lack of information about post-surgery ED; 2) negative emotional impact of ED and avoidance of sexual situations; 3) negative emotional experience with penile injections and barriers leading to avoidance; 4) the benefit of focusing on the long-term advantage of ER versus short-term anxiety; 5) using humor to help cope; and 6) the benefit of support from partners and peers. Conclusions Men's frustration surrounding ED can lead to avoidance of sexual situations and ED treatments, which negatively impact men's adherence to an ER program. The theoretical construct of Acceptance and Commitment Therapy (ACT) was used to place the themes into a framework to conceptualize the mechanisms underlying both avoidance and adherence in this population. As such, ACT has the potential to serve as a conceptual underpinning of a psychological intervention to help men reduce avoidance to penile injections and adhere to an ER program. PMID:25707812

Avoiding math on a rapid timescale: Emotional responsivity and anxious attention in math anxiety.

Math anxiety (MA) is characterized by negative feelings towards mathematics, resulting in avoidance of math classes and of careers that rely on mathematical skills. Focused on a long timescale, this research may miss important cognitive and affective processes that operate moment-to-moment, changing rapid reactions even when a student simply sees a math problem. Here, using fMRI with an attentional deployment paradigm, we show that MA influences rapid spontaneous emotional and attentional responses to mathematical stimuli upon brief presentation. Critically, participants viewed but did not attempt to solve the problems. Indicating increased threat reactivity to even brief presentations of math problems, increased MA was associated with increased amygdala response during math viewing trials. Functionally and anatomically defined amygdala ROIs yielded similar results, indicating robustness of the finding. Similar to the pattern of vigilance and avoidance observed in specific phobia, behavioral results of the attentional paradigm demonstrated that MA is associated with attentional disengagement for mathematical symbols. This attentional avoidance is specific to math stimuli; when viewing negatively-valenced images, MA is correlated with attentional engagement, similar to other forms of anxiety. These results indicate that even brief exposure to mathematics triggers a neural response related to threat avoidance in highly MA individuals. Copyright © 2017 Elsevier Inc. All rights reserved.

Evidence suggests that insight in psychosis has been related to treatment adherence, recovery and good prognosis, but also to depression, low self-esteem, and diminished quality of life. Thus, insight might not be advantageous under all circumstances. Internalized-stigma (i.e. self-acceptance of stigmatizing images of illness) and experiential avoidance (i.e. unwillingness to experience negative private events) have been proposed as moderating variables between insight, and psychological health variables and/or distress. We investigated the patterns of association of insight with satisfaction with life, self-esteem, depression, anxiety and psychotic psychopathology as moderated by self-stigmatizing beliefs and experiential avoidance, in a sample of 47 participants with persecutory beliefs and diagnosed with schizophrenia or other psychotic disorder. Moderation analyses confirm the importance of internalized-stigma and experiential avoidance. The presence of insight was associated with more depression when there were high levels of self-stigma. Whereas, the absence of insight was associated with a greater life satisfaction when there were high levels of experiential avoidance. To summarize, our results help understand the complex relationship between insight, psychological health variables and emotional distress, pointing to a differential pattern of moderation for negative and positive outcomes. We discuss the implications of these results for research and treatment of paranoia. Copyright © 2015 Elsevier B.V. All rights reserved.

More investigation is needed to understand how specific posttraumatic stress disorder (PTSD) symptom clusters relate to the internal experience of anger and overt negative behaviors in response to anger (negative expressivity). We investigated whether anger mediated relations between PTSD symptom clusters and negative expressivity. Multiple regression revealed lower PTSD intrusion symptoms associated with higher levels of negative expressivity. Anger mediated this relationship. Higher avoidance symptoms related to higher negative expressivity. Clinical implications, limitations, and strengths are discussed. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Cognitive distortion in depression is characterized by enhanced negative thoughts about both environment and oneself. Carriers of a risk allele for depression, that is, the short (s) allele of the serotonin transporter promoter polymorphism (5-HTTLPR), exhibit amygdala hyperresponsiveness to negative environmental stimuli relative to homozygous long variant (l/l). However, the neural correlates of negative self-schema in s allele carriers remain unknown. Using functional MRI, we scanned individuals with s/s or l/l genotype of the 5-HTTLPR during reflection on their own personality traits or a friend's personality traits. We found that relative to l/l carriers, s/s carriers showed stronger distressed feelings and greater activity in the dorsal anterior cingulate (dACC)/dorsal medial prefrontal cortex (dmPFC) and the right anterior insula (AI) during negative self-reflection. The 5-HTTLPR effect on the distressed feelings was mediated by the AI/inferior frontal (IF) activity during negative self-reflection. The dACC/dmPFC activity explained 20% of the variation in harm-avoidance tendency in s/s but not l/l carriers. The genotype effects on distress and brain activity were not observed during reflection on a friend's negative traits. Our findings reveal that 5-HTTLPR polymorphism modulates distressed feelings and brain activities associated with negative self-schema and suggest a potential neurogenetic susceptibility mechanism for depression. © The Author 2013.

Chronic infections are caused by microorganisms that display effective immune evasion mechanisms. Dendritic cell (DC)-dependent T cell-mediated adaptive immunity is one of the mechanisms that have evolved to prevent the occurrence of chronic bacterial infections. In turn, bacterial pathogens have developed strategies to evade immune recognition. In this study, we show that gram-negative and gram-positive bacteria differ in their ability to activate DCs and that gram-negative bacteria are far more effective inducers of DC maturation. Moreover, we observed that only gram-negative bacteria can induce loss of adhesive podosome structures in DCs, a response necessary for the induction of effective DC migration. We demonstrate that the ability of gram-negative bacteria to trigger podosome turnover and induce DC migration reflects their capacity to selectively activate TLR4. Examining mice defective in TLR4 signaling, we show that this DC maturation and migration are mainly Toll/IL-1 receptor domain-containing adaptor-inducing IFNbeta-dependent. Furthermore, we show that these processes depend on the production of PGs by these DCs, suggesting a direct link between TLR4-mediated signaling and arachidonic metabolism. These findings demonstrate that gram-positive and gram-negative bacteria profoundly differ in their capacity to activate DCs. We propose that this inability of gram-positive bacteria to induce DC maturation and migration is part of the armamentarium necessary for avoiding the induction of an effective cellular immune response and may explain the frequent involvement of these pathogens in chronic infections.

New parasitoid-predator associations: female parasitoids do not avoid competition with generalist predators when sharing invasive prey

Optimal habitat selection is essential for species survival in ecosystems, and interspecific competition is a key ecological mechanism for many observed species association patterns. Specialized animal species are commonly affected by resource and interference competition with generalist and/or omnivorous competitors, so avoidance behavior could be expected. We hypothesize that specialist species may exploit broad range cues from such potential resource competitors (i.e., cues possibly common to various generalist and/or omnivorous predators) to avoid costly competition regarding food or reproduction, even in new species associations. We tested this hypothesis by studying short-term interactions between a native larval parasitoid and a native generalist omnivorous predator recently sharing the same invasive host/prey, the leaf miner Tuta absoluta. We observed a strong negative effect of kleptoparasitism (food resource stealing) instead of classical intraguild predation on immature parasitoids. There was no evidence that parasitoid females avoided the omnivorous predator when searching for oviposition sites, although we studied both long- and short-range known detection mechanisms. Therefore, we conclude that broad range cue avoidance may not exist in our biological system, probably because it would lead to too much oviposition site avoidance which would not be an efficient and, thus, beneficial strategy. If confirmed in other parasitoids or specialist predators, our findings may have implications for population dynamics, especially in the current context of increasing invasive species and the resulting creation of many new species associations.

Attachment theory and group processes: the association between attachment style and group-related representations, goals, memories, and functioning.

Four studies examined attachment-style differences in group-related cognitions and behaviors. In Studies 1-2, participants completed scales on group-related cognitions and emotions. In Studies 3-4, participants were divided into small groups, and their performance in group tasks as well as the cohesion of their group were assessed. Both attachment anxiety and avoidance in close relationships were associated with negative group-related cognitions and emotions. Anxiety was also related to the pursuit of closeness goals and impaired instrumental performance in group tasks. Avoidance was related to the pursuit of distance goals and deficits in socioemotional and instrumental performance. Group cohesion significantly moderated the effects of attachment anxiety. The discussion emphasizes the relevance of attachment theory within group contexts.

Animal studies indicate that sex hormones have widespread effects on the brain, cognition and emotion, but findings in humans are inconsistent. Well-controlled studies in nonhuman primates are crucial to resolve these discrepancies. In this study, we examined the effects of testosterone (T) on emotion in male rhesus monkeys. Six young adult males were tested on two emotional tasks during three hormonal conditions in a crossover design: when intact at baseline and when pharmacologically hypogonadal with add-back of T or placebo. The emotional tasks were the Approach-Avoidance task, which tested behavioral responses to three categories of objects (familiar, novel, and negative) and a Social Playback task which tested behavioral responses to scenes of unfamiliar conspecifics engaged in three types of social activities (neutral, positive, or negative). Following a 4-week baseline period, monkeys were treated with Depot Lupron, 200μg/kg before being randomly assigned to one of two treatment groups: Depot Lupron+Testosterone Enanthate (TE, 20mg/kg) or Depot Lupron+oil vehicle. In each treatment group, monkeys received one injection of Lupron and one injection of TE or one injection of Lupron and one injection of oil at the onset of a 4-week testing period, before crossing over to the alternate treatment for an additional 4weeks of testing. TE treatment had no effect on behavioral measures in the Approach-Avoidance task. For the Social Playback task, however, TE significantly increased watching time of video clips which depicted fights between unfamiliar conspecifics. The enhancing effect of T on watching time for negative social scenes is consistent with human data suggesting that T decreases aversion or facilitates approach to threatening social stimuli. Further studies are needed to understand the mechanisms by which T may mediate responsiveness to social threat in male primates. Copyright © 2010 Elsevier Inc. All rights reserved.

Ashamed and Fused with Body Image and Eating: Binge Eating as an Avoidance Strategy.

Binge Eating Disorder (BED) is currently recognized as a severe disorder associated with relevant psychiatric and physical comorbidity, and marked emotional distress. Shame is a specific negative emotion that has been highlighted as central in eating disorders. However, the effect of shame and underlying mechanisms on binge eating symptomatology severity remained unclear. This study examines the role of shame, depressive symptoms, weight and shape concerns and eating concerns, and body image-related cognitive fusion, on binge eating symptomatology severity. Participated in this study 73 patients with the diagnosis of BED, established through a clinical interview-Eating Disorder Examination 17.0D-who completed measures of external shame, body-image related cognitive fusion, depressive symptoms and binge eating symptomatology. Results revealed positive associations between binge eating severity and depressive symptoms, shame, weight and shape concerns, eating concerns and body image-related cognitive fusion. A path analysis showed that, when controlling for the effect of depressive symptoms, external shame has a direct effect on binge eating severity, and an indirect effect mediated by increased eating concern and higher levels of body image-related cognitive fusion. Results confirmed the plausibility of the model, which explained 43% of the severity of binge eating symptoms. The proposed model suggests that, in BED patients, perceiving that others see the self negatively may be associated with an entanglement with body image-related thoughts and concerns about eating, which may, in turn, fuel binge eating symptoms. Findings have important clinical implications supporting the relevance of addressing shame and associated processes in binge eating. Copyright © 2015 John Wiley & Sons, Ltd. Shame is a significant predictor of symptomatology severity of BED patients. Shame significantly impacts binge eating, even controlling for depressive symptoms. Shame significantly predicts body image-related cognitive fusion and eating concern. Body image-fusion and eating concern mediate the link between shame and binge eating. Binge eating may be seen as an avoidance strategy from negative self-evaluations. Copyright © 2015 John Wiley & Sons, Ltd.

An anti-herbivore defense mutualism under elevated CO2 levels

DOE Office of Scientific and Technical Information (OSTI.GOV)

Marks, S.; Lincoln, D.E.

Previous studies have shown that insects typically consume more when fed leaf tissue grown under CO2 enrichment, but with few negative effects on growth. On the other hand, Lepidopteran larvae fed tissue infected with Balansiae fungal endophytes (which produce toxic alkaloids) typically eat less but suffer negative effects on growth and survival. This study was carried out to see how these two factors would interact to affect consumption and growth of Fall Armyworm larvae (Spodoptera frugiperda). Infected and uninfected ramets of a single genotype of tall fescue (Festuca arundinacea) were grown under CO2 concentrations of 400 and 700 ul/L. Larvaemore » had increased relative growth in the high CO2 treatment, but decreased growth when fed infected tissue. Relative consumption of leaf tissue was greater in the high CO2 treatment, but was not effected by infection. CO2 level, infection, and their interaction all significantly reduced the efficiency of conversion of food ingested (ECI). It appears that tall fescue may not be as well defended against herbivores under CO2 enrichment, although insects may still avoid and be negatively effected by endophyte infected plants.« less

Shape dependence of slip length on patterned hydrophobic surfaces

2011-08-01

The effects of solid-liquid interfacial shape on the boundary velocity slip of patterned hydrophobic surfaces are investigated. The scaling law in literature is extended to demonstrate the role of such shape, indicating a decrease of the effective slip length with increasing interfacial roughness. A patterned surface with horizontally aligned carbon nanotube arrays reaches an effective slip length of 83 nm, by utilizing large intrinsic slippage of carbon nanotube while keeping away from the negative effects of interfacial curvature through the flow direction. The results emphasize the importance of avoiding the solid-liquid interfacial roughness in low-friction patterned surface design and manufacture.

Butterflies Do Not Alter Conspecific Avoidance in Response to Variation in Density.

PubMed

Jaumann, Sarah; Snell-Rood, Emilie C

2017-08-01

High conspecific densities are associated with increased levels of intraspecific competition and a variety of negative effects on performance. However, changes in life history strategy could compensate for some of these effects. For instance, females in crowded conditions often have fewer total offspring, but they may invest more in each one. Such investment could include the production of larger offspring, more time spent engaging in parental care, or more choosy decisions about where offspring are placed. For animals that have a relatively immobile juvenile stage, the costs of competition can be particularly high. Females may be able to avoid such costs by investing more in individual reproductive decisions, rearing young or laying eggs in locations away from other females. We tested the hypothesis that conspecific density cues during juvenile and adult life stages lead to changes in life history strategy, including both reproduction and oviposition choices. We predicted that high-density cues during the larval and adult stages of female Pieris rapae butterflies lead to lower fecundity but higher conspecific avoidance during oviposition, compared to similar low-density cues. We used a 2×2 factorial design to examine the effects of low and high conspecific density during the larval and adult stages of butterflies on avoidance behavior and fecundity. We found that past information about conspecific density did not matter; all butterflies exhibited similar levels of fecundity and a low level of conspecific avoidance during oviposition regardless of their previous experience as larvae and adults. These results suggest that P. rapae females use a fixed, rather than flexible, conspecific avoidance strategy when making oviposition decisions, and past information about conspecific density has no effect on life history and current reproductive investment. We speculate that this may be partially because past conspecific density per se is not a reliable cue for predicting current density and levels of competition, and thus it does not affect the development of life history strategies in this system. © The Author 2017.

2013-12-01

Stimulation of patients' immune systems for the treatment of solid tumors is an emerging therapeutic paradigm. The use of enriched autologous T cells for adoptive cell therapy or vaccination with antigen-loaded dendritic cells have shown clinical efficacy in melanoma and prostate cancer, respectively. However, the long-term effects of immune responses on selection and outgrowth of antigen-negative tumor cells in specific tumor types must be determined to understand and achieve long-term therapeutic effects. In this study, we have investigated the expression of a tumor-specific antigen in situ after treatment with tumor-specific CD8(+) T cells in an autochthonous mouse model of prostate cancer. After T-cell treatment, aggregates of dead antigen-positive tumor cells were concentrated in the lumen of the prostate gland and were eventually eliminated from the prostate tissue. Despite the elimination of antigen-positive tumor cells, prostate tumor continued to grow in T-cell-treated mice. Interestingly, the remaining tumor cells were antigen negative and downregulated MHC class I expression. These results show that CD8(+) T cells are effective in eliminating antigen-bearing prostate tumor cells but they also can select for the outgrowth of antigen-negative tumor cells. These findings provide insights into the requirements for an effective cancer immunotherapy within the prostate that not only induces potent immune responses but also avoids selection and outgrowth of antigen-negative tumor cells. ©2013 AACR.

Objectives: Post-traumatic growth (PTG) and its opposite—post-traumatic depreciation (PTD)—may be treated as important indicators of the patient quality of life. In the absence of studies on both, PTG and PTD in cancer patients, we investigated (1) coping strategies and support effectiveness as predictors of PTG and PTD in post-mastectomy women, (2) homogeneous classes with different intensity of PTG and PTD symptoms, and (3) correlates of class membership. Methods: Coping strategies (Brief COPE), support effectiveness (SSE-Q), PTG (PTGI), and PTD (negatively reworded items of PTGI) were measured in 84 post-mastectomy women (mean age = 62.27, SD = 8.38). Multiple regression, two-step cluster, and multinomial logistic regression were applied. Results: PTG and PTD had unique predictors: time since diagnosis and positive emotion-focused coping predicted PTG (R2 = 0.24), while negative emotion-focused and avoidance-focused coping and low support effectiveness were linked to PTD (R2 = 0.14). Four groups of PTG × PTD symptoms were identified: high PTG low PTD group (52.4%), low PTG low PTD group (17.9%), high PTG high PTD group (15.5%), and low PTG high PTD group (14.3%). Higher emotion- and avoidance-focused coping was characteristic for the high PTD low PTG group (R2 = 0.41). Conclusion: Our findings shed light on the coexistence and unique predictors of PTG and PTD after mastectomy, indicating heterogeneity in PTG and PTD levels among post-mastectomy women.

This study aimed to assess possible interactive effects of coping styles and psychological stress on depression and anxiety symptoms in Chinese patients with Type 2 diabetes. Three hundred and four patients with Type 2 diabetes underwent a face-to-face interview by trained research staff according to a standardized questionnaire including information on socio-demographic characteristics, psychological stress, coping styles and anxiety and depressive symptoms. The interactive effects of coping styles and psychological stress on depression and anxiety symptoms were assessed by hierarchical multiple regression analyses. There were significant associations of the four domains of psychological stress with anxiety and depressive symptoms, except for the relationship between 'reduced economic condition' and depressive symptoms. 'Negative coping style' significantly increased the level of both anxiety and depressive symptoms; whereas, 'active coping style' and 'avoidant coping style' decreased the risk of depressive symptoms. The interactions of 'negative coping style' with 'worrying about decline in body/physical function' and 'reduced economic condition' significantly increased the risk of anxiety and depressive symptoms, and the interaction of 'social/family crisis caused by the disease' with 'avoidance coping style' and 'worrying about decline in body/physical function' with 'active coping style' significantly decreased the risk of depressive symptoms. The results of this study suggest that certain coping styles might moderate the association of psychological stress with anxiety and depressive symptoms in Chinese patients with Type 2 diabetes.

Neurons for hunger and thirst transmit a negative-valence teaching signal

Homeostasis is a biological principle for regulation of essential physiological parameters within a set range. Behavioural responses due to deviation from homeostasis are critical for survival, but motivational processes engaged by physiological need states are incompletely understood. We examined motivational characteristics and dynamics of two separate neuron populations that regulate energy and fluid homeostasis by using cell type-specific activity manipulations in mice. We found that starvation-sensitive AGRP neurons exhibit properties consistent with a negative-valence teaching signal. Mice avoided activation of AGRP neurons, indicating that AGRP neuron activity has negative valence. AGRP neuron inhibition conditioned preference for flavours and places. Correspondingly, deep-brain calcium imaging revealed that AGRP neuron activity rapidly reduced in response to food-related cues. Complementary experiments activating thirst-promoting neurons also conditioned avoidance. Therefore, these need-sensing neurons condition preference for environmental cues associated with nutrient or water ingestion, which is learned through reduction of negative-valence signals during restoration of homeostasis.

DEVELOPMENT AND MODIFICATION OF A RESPONSE CLASS VIA POSITIVE AND NEGATIVE REINFORCEMENT: A TRANSLATIONAL APPROACH

PubMed Central

Mendres, Amber E; Borrero, John C

2010-01-01

When responses function to produce the same reinforcer, a response class exists. Researchers have examined response classes in applied settings; however, the challenges associated with conducting applied research on response class development have recently necessitated the development of an analogue response class model. To date, little research has examined response classes that are strengthened by negative reinforcement. The current investigation was designed to develop a laboratory model of a response class through positive reinforcement (i.e., points exchangeable for money) and through negative reinforcement (i.e., the avoidance of scheduled point losses) with 11 college students as participants and clicks as the operant. Results of both the positive and negative reinforcement evaluations showed that participants usually selected the least effortful response that produced points or the avoidance of point losses, respectively. The applied implications of the findings are discussed, along with the relevance of the present model to the study of punishment and resurgence. PMID:21541150

[Valences of self-evaluation and approach-avoidance tendencies: research based on regulatory focus theory].

Four studies were conducted to investigate the relationship between valences of self-evaluation and approach-avoidance tendencies. Based on regulatory focus theory (Higgins, 1997, 1998), we predicted that positivity of self-evaluation is related to the tendency to approach gains, while negativity of self-evaluation is related to the tendency to avoid losses. In Study 1, a self-report measure of behavioral tendencies for approaching gains and avoiding losses was developed. In Studies 2 to 4, correlations between these approach/avoidance tendencies and various kinds of self-evaluations were examined. Overall, the authors' predictions were supported. The results suggest that the self-evaluation system and the self-regulation system work in close cooperation with each other in controlling human behavior.

For reasons of bureaucracy and safety, astronauts on the International Space Station are provided with excruciatingly detailed instructions and a lack of decision-making power, even for simple routine tasks. Besides being time-consuming, many astronauts report feelings of demotivation, irritation, and even defiance when confronted with this working method. Anecdotic evidence suggests that this method leads to situations where astronauts read instructions diagonally or avoid checking in with mission support, thereby ironically increasing the risk of error making. There is a need to consider under which circumstances, for whom, and why the provision of long instructions could be detrimental for well-being and performance. An experimental study with LEGO assembly tasks examined whether length of instructions (i.e. short versus long) and task complexity (simple vs. complex) impact negative affect, motivational experiences and performance of participants (N = 113, Mage = 18.75 ± 2.46 years). Long instructions for simple tasks provoked greater feelings of irritation, diminished the perceived value of instructions, and negatively influenced productivity and accuracy. The negative effect of long instructions on irritation was explained via decreased perceived value. Additionally, the effect of length of instructions on irritation differed for participants high versus those low in need for achievement.

Negativity bias and task motivation: testing the effectiveness of positively versus negatively framed incentives.

People are frequently challenged by goals that demand effort and persistence. As a consequence, philosophers, psychologists, economists, and others have studied the factors that enhance task motivation. Using a sample of undergraduate students and a sample of working adults, we demonstrate that the manner in which an incentive is framed has implications for individuals' task motivation. In both samples we find that individuals are less motivated when an incentive is framed as a means to accrue a gain (positive framing) as compared with when the same incentive is framed as a means to avoid a loss (negative framing). Further, we provide evidence for the role of the negativity bias in this effect, and highlight specific populations for whom positive framing may be least motivating. Interestingly, we find that people's intuitions about when they will be more motivated show the opposite pattern, with people predicting that positively framed incentives will be more motivating than negatively framed incentives. We identify a lay belief in the positive correlation between enjoyment and task motivation as one possible factor contributing to the disparity between predicted and actual motivation as a result of the framing of the incentive. We conclude with a discussion of the managerial implications for these findings. PsycINFO Database Record (c) 2013 APA, all rights reserved.

Objective Although much attention has been given to the effects of adverse childhood experiences on the development of personality disorders (PDs), we know far less about how recent life events influence the ongoing course of functioning. We examined the extent to which PD subjects differ in rates of life events and the extent to which life events impact psychosocial functioning. Method A total of 633 subjects were drawn from the Collaborative Longitudinal Personality Disorders Study (CLPS), a multi-site study of four personality disorders – schizotypal (STPD), borderline (BPD), avoidant (AVPD), obsessive-compulsive (OCPD) – and a comparison group of major depressive disorders (MDD) without PD. Results Borderline personality disorder subjects reported significantly more total negative life events than other PDs or subjects with MDD. Negative events, especially interpersonal events, predicted decreased psychosocial functioning over time. Conclusion Our findings indicate higher rates of negative events in subjects with more severe PDs and suggest that negative life events adversely impact multiple areas of psychosocial functioning.

Stereotype threat and performance: how self-stereotypes influence processing by inducing regulatory foci.

PubMed

Seibt, Beate; Förster, Jens

2004-07-01

The authors hypothesized that activated self-stereotypes can influence the strategies of task solution by inducing regulatory foci. More specifically, positive self-stereotypes should induce a promotion focus state of eagerness, whereas negative stereotypes should induce a prevention focus state of vigilance. Study 1 showed that a negative ascribed stereotype with regard to task performance leads to better recall for avoidance-related statements whereas a positive stereotype leads to better recall for approach-related statements. In Studies 2 and 3, both an experimental manipulation of group performance expectation and the preexisting stereotype of better verbal skills in women than in men led to faster and less accurate performance in the positive as compared with the negative stereotype group. Studies 4 and 5 showed that positive in-group stereotypes led to more creative performance whereas negative stereotypes led to better analytical performance. These results point to a possible mechanism for stereotype-threat effects. Copyright 2004 American Psychological Association

Possible positive reinforcing and aversive effects of intraperitoneally (ip) administered substance P (SP) and its C-terminal heptapeptide analog [pGlu5, MePhe8, Sar9]-SP5-11 (DIME-C7) were investigated in rats. The 'conditioned corral preference and avoidance procedure' was used for assessing positive and negative reinforcement. Behavioural testing was conducted in a circular open field consisting of four uniform quadrants equally preferred by the rats prior to drug treatment. On 3 consecutive days, rats received an ip injection of either SP (37 nmol/kg), DIME-C7 (3.7, 7.4, 37, 185 nmol/kg) or vehicle (0.01 M acetic acid in saline) and were placed immediately into their assigned treatment corral. During the test for conditioned corral preference and avoidance, when provided a choice between the four quadrants, rats treated with SP and with the equimolar dose of DIME-C7 (37 nmol/kg) spent significant more time in the drug-paired corral, indicative of positive reinforcing effects. The doses of 3.7 and 7.4 nmol/kg DIME-C7 did not influence the preference behaviour. The high dose of 185 nmol/kg DIME-C7 led to a significant decrease in time spent in the previously drug-paired corral, suggestive of aversive effects of the treatment. Gross locomotor activity was not influenced by either treatment. These results are discussed in the framework of a structure/activity relationship for the reinforcing properties of peripheraly applied SP.

Attentional bias in restrictive eating disorders. Stronger attentional avoidance of high-fat food compared to healthy controls?

PubMed

Veenstra, Esther M; de Jong, Peter J

2012-02-01

A striking feature of the restricting subtype of anorexia nervosa (AN) is that these patients are extremely successful in restricting their food intake. Possibly, they are highly efficient in avoiding attentional engagement of food cues, thereby preventing more elaborate processing of food cues and thus subsequent craving. This study examined whether patients diagnosed with restrictive eating disorders ('restricting AN-like patients'; N=88) indeed show stronger attentional avoidance of visual food stimuli than healthy controls (N=76). Attentional engagement and disengagement were assessed by means of a pictorial exogenous cueing task, and (food and neutral) pictures were presented for 300, 500, or 1000 ms. In the 500 ms condition, both restricting AN-like patients and healthy controls demonstrated attentional avoidance of high-fat food as indexed by a negative cue-validity effect and impaired attentional engagement with high-fat food, whereas no evidence was found for facilitated disengagement from high-fat food. Within the group of restricting AN-like patients, patients with relatively severe eating pathology showed relatively strong attentional engagement with low-fat food. There was no evidence for attentional bias in the 300 and 1000 ms condition. The pattern of findings indicate that attentional avoidance of high-fat food is a common phenomenon that may become counterproductive in restricting AN-like patients, as it could facilitate their restricted food intake.

Medical device regulations which aim to ensure safety standards do not only apply to hardware devices but also to standalone medical software, e.g. mobile apps. To explore the effects of these regulations on the development and distribution of medical standalone software. We invited a convenience sample of 130 domain experts to participate in an online survey about the impact of current regulations on the development and distribution of medical standalone software. 21 respondents completed the questionnaire. Participants reported slight positive effects on usability, reliability, and data security of their products, whereas the ability to modify already deployed software and customization by end users were negatively impacted. The additional time and costs needed to go through the regulatory process were perceived as the greatest obstacles in developing and distributing medical software. Further research is needed to compare positive effects on software quality with negative impacts on market access and innovation. Strategies for avoiding over-regulation while still ensuring safety standards need to be devised.

The aim of the present experiment was to determine if a niacin supplementation of 6 g/d to lactating dairy cow diets can compensate negative effects of a rumen nitrogen balance (RNB) deficit. A total of nine ruminally and duodenally fistulated lactating multiparous German Holstein cows were successively assigned to one of three diets consisting of 10 kg maize silage (dry matter [DM] basis) and 7 kg DM concentrate: Diet RNB- (n = 6) with energy and utilisable crude protein at the duodenum (uCP) according to the average requirement of the animals but with a negative RNB (-0.41 g N/MJ metabolisable energy [ME]); Diet RNB0 (n = 7) with energy, uCP and a RNB (0.08 g N/MJ ME) according to the average requirement of the animals and, finally, Diet NA (n = 5), which was the same diet as RNB-, but supplemented with 6 g niacin/d. Samples of milk were taken on two consecutive days, blood samples were taken on one day pre- and post-feeding and faeces and urine were collected completely over five consecutive days. The negative RNB reduced milk and blood urea content and apparent total tract digestibility of DM, organic matter (OM) and neutral detergent fibre (NDF). Also N excretion with urine, the total N excreted with urine and faeces and the N balance were reduced when the RNB was negative. Supplementation of niacin elevated plasma glucose concentration after feeding and the N balance increased. Supplementing the diet with a negative RNB with niacin led to a more efficient use of dietary N thereby avoiding the negative effects of the negative RNB on the digestibility of DM, OM and NDF.

Working Memory Load and Negative Picture Processing: Neural and Behavioral Associations With Panic, Social Anxiety, and Positive Affect.

Internalizing disorders such as anxiety may be characterized by an imbalance between bottom-up (stimulus-driven) and top-down (goal-directed) attention. The late positive potential (LPP) can be used to assess these processes when task-irrelevant negative and neutral pictures are presented within a working memory paradigm. Prior work using this paradigm has found that working memory load reduces the picture-elicited LPP across participants; however, anxious individuals showed a reduced effect of working memory load on the LPP, suggesting increased distractibility. The current study assessed transdiagnostic associations between specific symptom dimensions of anxiety, the LPP, and behavior in a clinically representative, heterogeneous group of 76 treatment-seeking patients with internalizing disorders, who performed a working memory task interspersed with negative and neutral pictures. As expected, negative pictures enhanced the LPP, and working memory load reduced the LPP. Participants with higher social anxiety showed increased LPPs to negative stimuli during early and late portions of picture presentation. Panic symptoms were associated with reduced LPPs to negative pictures compared with neutral pictures as well as a reduced effect of working memory load on the LPP during the late time window. Reduced positive affect was associated with greater behavioral interference from negative pictures. Hypervigilance for negative stimuli was uniquely explained by social anxiety symptoms, whereas panic symptoms were associated with the opposing effect-blunted processing/avoidance of these stimuli. Panic symptoms were uniquely associated with reduced top-down control. Results reveal distinct associations between neural reactivity and anxiety symptom dimensions that transcend traditional diagnostic boundaries. Copyright © 2018 Society of Biological Psychiatry.

Feed-backs among inbreeding, inbreeding depression in sperm traits, and sperm competition can drive evolution of costly polyandry.

PubMed

Bocedi, Greta; Reid, Jane M

2017-12-01

Ongoing ambitions are to understand the evolution of costly polyandry and its consequences for species ecology and evolution. Emerging patterns could stem from feed-back dynamics between the evolving mating system and its genetic environment, defined by interactions among kin including inbreeding. However, such feed-backs are rarely considered in nonselfing systems. We use a genetically explicit model to demonstrate a mechanism by which inbreeding depression can select for polyandry to mitigate the negative consequences of mating with inbred males, rather than to avoid inbreeding, and to elucidate underlying feed-backs. Specifically, given inbreeding depression in sperm traits, costly polyandry evolved to ensure female fertility, without requiring explicit inbreeding avoidance. Resulting sperm competition caused evolution of sperm traits and further mitigated the negative effect of inbreeding depression on female fertility. The evolving mating system fed back to decrease population-wide homozygosity, and hence inbreeding. However, the net overall decrease was small due to compound effects on the variances in sex-specific reproductive success and paternity skew. Purging of deleterious mutations did not eliminate inbreeding depression in sperm traits or hence selection for polyandry. Overall, our model illustrates that polyandry evolution, both directly and through sperm competition, might facilitate evolutionary rescue for populations experiencing sudden increases in inbreeding. © 2017 The Author(s).

This study evaluated similarities and differences in 2½ year-old children’s reactions to maternal unavailability during a brief still-face episode and subsequent resumption of social interaction during a reunion episode. Seventy mothers and children were videotaped in the Toddler Still-Face paradigm (T-SF), an age appropriate adaptation of the Face-to-Face Still-Face paradigm. Similar to their younger counterparts, 2½ year-olds displayed the traditional “still-face effect,” including an increase in negative affect, gaze aversion, and a wide array of behaviors indicative of proximity seeking to the mother, solicitation of her attention, and avoidance and a “reunion effect,” characterized by a carryover of negative affect and avoidance behavior (e.g., moving away from the mother) from the still-face episode to the reunion play episode. However, differences in toddlers’ behaviors during the still-face and reunion episodes were also observed, which highlight age-related changes in the toddlers’ ability to cope with the stress of maternal unavailability during the still-face during the third year of life. Contrary to reports for younger infants, few gender differences were found in toddlers’ reactions to the still-face. The findings support the hypothesis that the toddlers are attempting to make meaning out of an unexpected and senseless event. PMID:22384309

Anticipatory anxiety and harm avoidance are essential features of panic disorder (PD) and may involve deficits in the reward system of the brain, in particular in the ventral striatum. While neuroimaging studies on PD have focused on fearful and negative affective stimulus processing, no investigations have directly addressed deficits in reward and loss anticipation. To determine whether the ventral striatum shows abnormal neural activity in PD patients during anticipation of loss or gain, an event-related functional magnetic resonance imaging experiment using a monetary incentive delay task was employed in 10 patients with PD and 10 healthy controls. A repeated-measures ANOVA to identify effects of group (PD vs. Control) and condition (anticipation of loss vs. gain vs. neutral outcome) revealed that patients with PD showed significantly reduced bilateral ventral striatal activation during reward anticipation but increased activity during loss anticipation. Within the patient group, the degree of activation in the ventral striatum during loss-anticipation was positively correlated with harm avoidance and negatively correlated with novelty seeking. These findings suggest that behavioural impairments in panic disorder may be related to abnormal neural processing of motivational cues. Copyright © 2017 Elsevier B.V. All rights reserved.

Currently, cognitive behavioral therapies appear to be one of the most studied treatments for gambling problems and studies show it is effective in treating gambling problems. However, cognitive behavior models have not been widely tested using statistical means. Thus, the aim of this study was to test the validity of the pathways postulated in the cognitive behavioral theory of gambling behavior using structural equation modeling (AMOS 20). Several questionnaires assessing a range of gambling specific variables (e.g., gambling urges, cognitions and behaviors) and gambling correlates (e.g., psychological states, and coping styles) were distributed to 969 participants from the community. Results showed that negative psychological states (i.e., depression, anxiety and stress) only directly predicted gambling behavior, whereas gambling urges predicted gambling behavior directly as well as indirectly via gambling cognitions. Avoidance coping predicted gambling behavior only indirectly via gambling cognitions. Negative psychological states were significantly related to gambling cognitions as well as avoidance coping. In addition, significant gender differences were also found. The results provided confirmation for the validity of the pathways postulated in the cognitive behavioral theory of gambling behavior. It also highlighted the importance of gender differences in conceptualizing gambling behavior.

Common mental health consequences following the experience of potentially traumatic events include Posttraumatic Stress Disorder (PTSD) and addictive behaviors. Problematic smartphone use is a newer manifestation of addictive behaviors. People with anxiety severity (such as PTSD) may be at risk for problematic smartphone use as a means of coping with their symptoms. Unique to our knowledge, we assessed relations between PTSD symptom clusters and problematic smartphone use. Participants ( N = 347), recruited through Amazon's Mechanical Turk (MTurk), completed measures of PTSD and smartphone addiction. Results of the Wald tests of parameter constraints indicated that problematic smartphone use was more related to PTSD's negative alterations in cognitions and mood (NACM) than to PTSD's avoidance factor, Wald χ 2 (1, N = 347) = 12.51, p = 0.0004; and more to PTSD's arousal compared to PTSD's avoidance factor, Wald χ 2 (1, N = 347) = 14.89, p = 0.0001. Results indicate that problematic smartphone use is most associated with negative affect and arousal among trauma-exposed individuals. Implications include the need to clinically assess problematic smartphone use among trauma-exposed individuals presenting with higher NACM and arousal severity; and targeting NACM and arousal symptoms to mitigate the effects of problematic smartphone use.

Aging and goal-directed emotional attention: distraction reverses emotional biases.

Previous findings reveal that older adults favor positive over negative stimuli in both memory and attention (for a review, see Mather & Carstensen, 2005). This study used eye tracking to investigate the role of cognitive control in older adults' selective visual attention. Younger and older adults viewed emotional-neutral and emotional-emotional pairs of faces and pictures while their gaze patterns were recorded under full or divided attention conditions. Replicating previous eye-tracking findings, older adults allocated less of their visual attention to negative stimuli in negative-neutral stimulus pairings in the full attention condition than younger adults did. However, as predicted by a cognitive-control-based account of the positivity effect in older adults' information processing tendencies (Mather & Knight, 2005), older adults' tendency to avoid negative stimuli was reversed in the divided attention condition. Compared with younger adults, older adults' limited attentional resources were more likely to be drawn to negative stimuli when they were distracted. These findings indicate that emotional goals can have unintended consequences when cognitive control mechanisms are not fully available.

From the perspectives of time perception and motivation, socioemotional selectivity theory (SST) postulates that in comparison with younger adults, older adults tend to prefer positive stimuli and avoid negative stimuli. Currently the cross-cultural consistency of this positivity effect (PE) is still not clear. While empirical evidence for Western populations is accumulating, the validation of the PE in Asians is still rare. The current study compared 28 younger and 24 older Chinese adults in the processing of emotional information. Eye-tracking and recognition data of participants in processing pictures with positive, negative, or neutral emotional information sampled from the International Affection Picture System were collected. The results showed less negative bias for emotional attention in older adults than in younger adults, whereas for emotional recognition, only younger adults showed a negative bias while older adults showed no bias between negative and positive emotional information. Overall, compared with younger adults, emotional processing was more positive in older adults. It was concluded that Chinese older adults show a PE. © 2015 The Institute of Psychology, Chinese Academy of Sciences and Wiley Publishing Asia Pty Ltd.

Healey, Dione M; Marks, David J; Halperin, Jeffrey M

2011-05-01

Cognition and emotion, traditionally thought of as largely distinct, have recently begun to be conceptualized as dynamically linked processes that interact to influence functioning. This study investigated the moderating effects of cognitive functioning on the relationship between negative emotionality and attention deficit/hyperactivity disorder (ADHD) symptom severity. A total of 216 (140 hyperactive/inattentive; 76 typically developing) preschoolers aged 3-4 years were administered a neuropsychological test battery (i.e., NEPSY). To avoid method bias, child negative emotionality was rated by teachers (Temperament Assessment Battery for Children-Revised), and parents rated symptom severity on the ADHD Rating Scale (ADHD-RS-IV). Hierarchical Linear Regression analyses revealed that both negative emotionality and Perceptual-Motor & Executive Functions accounted for significant unique variance in ADHD symptom severity. Significant interactions indicated that when negative emotionality is low, but not high, neuropsychological functioning accounts for significant variability in ADHD symptoms, with lower functioning predicting more symptoms. Emotional and neuropsychological functioning, both individually and in combination, play a significant role in the expression of ADHD symptom severity.

Producing more persuasive antiviolence messages for college students: testing the effects of framing, information sources, and positive/negative fact appeal.

2012-06-01

College students, between the ages of about 18 and 24, are the group of people who are most often exposed to situations involving diverse types of violence. They have greater access to alcohol and drugs and are under far less parental supervision than younger age groups; reports have shown that frequent involvement in several types of violent behaviors can seriously damage college students physically and psychologically. However, despite the high rate of violence among college students, there has not been enough discussion about how we can produce more effective antiviolence messages targeting college students. This research provides some useful insights into this issue by testing the possible effects of three antiviolence message conditions: gain/loss framing, different information sources, and negative/positive fact appeal. The results reveal that college students in this study find more appeal in antiviolence messages conveyed by a traditional public service announcement (PSA) than in a TV news report. The results also reveal that people pay more attention to messages that use negative fact appeal (e.g., "There are many people losing a lot of precious things because of their violent behaviors") than to those that use positive fact appeal (e.g., "There are many people gaining a lot of precious things by avoiding violent behaviors"). An interaction effect between information sources and positive/negative fact appeal was also detected.

Given that dissatisfaction with bodily appearance can sometimes lead to the avoidance of personal contacts and the increase of internet use, this study examines this relationship. The direct role of dissatisfaction with bodily appearance along with the possible mediation effects of depression, anxiety and self-esteem were tested. A total of 694 participants completed an online questionnaire (58.5% male, mean age 21.5 years), containing measures on problematic internet use, depression and anxiety symptoms, self-esteem and satisfaction with body image. Path analyses were used to test direct and indirect effects. Satisfaction with body appearance had a significant negative direct effect on problematic internet use among both sexes. Though, satisfaction with body appearance had a positive effect on self-esteem and negative on anxiety, neither self-esteem nor anxiety had a direct significant effect on problematic internet use. The effect of dissatisfaction with body appearance was mediated via the self-esteem-depression path toward problematic internet use. Dissatisfaction with physical appearance seems to have a significant role in individuals' immersing themselves in internet use.

NEOTEC: Negative-CO2-Emissions Marine Energy With Direct Mitigation of Global Warming, Sea-Level Rise and Ocean Acidification

NASA Astrophysics Data System (ADS)

Rau, G. H.; Baird, J.; Noland, G.

2016-12-01

The vertical thermal energy potential in the ocean is a massive renewable energy resource that is growing due to anthropogenic warming of the surface and near-surface ocean. The conversion of this thermal energy to useful forms via Ocean Thermal Energy Conversion (OTEC) has been demonstrated over the past century, albeit at small scales. Because OTEC removes heat from the surface ocean, this could help directly counter ongoing, deleterious ocean/atmosphere warming. The only other climate intervention that could do this is solar radiation "geoengineering". Conventional OTEC requires energy intensive, vertical movement of seawater resulting in ocean and atmospheric chemistry alteration, but this can be avoided via more energy efficient, vertical closed-cycle heating and cooling of working fluid like CO2 or NH3. An energy carrier such as H2 is required to transport energy optimally extracted far offshore, and methods of electrochemically generating H2 while also consuming CO2 and converting it to ocean alkalinity have been demonstrated. The addition of such alkalinity to the ocean would provide vast, stable, carbon storage, while also helping chemically counter the effects of ocean acidification. The process might currently be profitable given the >$100/tonne CO2 credit offered by California's Low Carbon Fuel Standard for transportation fuels like H2. Negative-Emissions OTEC, NEOTEC, thus can potentially provide constant, cost effective, high capacity, negative-emissions energy while: a) reducing surface ocean heat load, b) reducing thermal ocean expansion and sea-level rise, c) utilizing a very large, natural marine carbon storage reservoir, and d) helping mitigate ocean acidification. The technology also avoids the biophysical and land use limitations posed by negative emissions methods that rely on terrestrial biology, such as afforestation and BECCS. NEOTEC and other marine-based, renewable energy and CO2 removal approaches could therefore greatly increase the likelihood of satisfying growing global energy demand while helping to stabilize or reduce atmospheric CO2 and its impacts. Policies supporting the search and evaluation of renewable energy and negative emissions options beyond biotic- and land-based methods are needed.

Over the course of a semester, students from six 4-year institutions viewed three life story videos (documentaries) of older adults and completed pre- and posttest surveys that assessed their positive (Allophilia Scale) and negative (Fraboni Scale of Ageism) attitudes. The authors assessed changes in attitudinal scales between treatment (with videos, n = 80) and control (no video, n = 40) groups. Change score analysis with 95% bias-corrected bootstrap confidence intervals estimated the effects of the documentaries on students' attitudes. The treatment group showed significant increases in kinship, engagement, and enthusiasm, and decreases in antilocution and avoidance (all ps <.05). There was no significant change in affect, comfort, or discrimination. This study demonstrated how video stories impact students' attitudes about older adults.

What happens when affective displays deviate from normative expectations? In this study, participants evaluated target individuals displaying flat, incongruent, or congruent expressions seemingly in response to pictures eliciting positive, neutral, or negative affect. Relative to targets who displayed normative reactions, those who violated affective norms (affective deviants) were rated more negatively on various dimensions of social judgment. Participants also preferred greater social distance from affective deviants, reported more moral outrage in response to them, and inferred that these targets did not share their moral values. Incongruent affect resulted in more negative social judgment than did flat affect, and this relationship was moderated by stimulus valence. Finally, the relationship between targets' affective expressions and participants' avoidant intentions was mediated by the extent to which participants thought the targets shared their moral values. These findings demonstrate the interpersonal costs of affective deviance, revealing the pervasiveness and force of affective norms.

Previous research of negative symptoms in schizophrenia has emphasized an anticipatory pleasure deficit, yet the relationship of this deficit to patients' motivation in everyday life is poorly understood. This study tested the link between anticipatory pleasure and two broad motivational systems that are said to regulate the intensity of approach and avoidance behavior, the Behavioral Inhibition system (BIS) and the Behavioral Activation System (BAS). It was hypothesized that high vulnerability for negative symptoms would be associated with low reward responsiveness and that this association will be mediated by the amount of anticipated pleasure. Students (n=171) with varying vulnerability for negative symptoms (assessed by the Community Assessment of Psychic Experiences) completed questionnaires regarding (a) anticipatory and consummatory pleasure, and (b) responsiveness to threat and reward. As hypothesized, anticipatory pleasure correlated significantly negatively with subclinical negative symptoms (r=-0.21) and significantly positively with BAS (r=0.55). Furthermore, evidence for a partial mediation effect was found. The findings support the notion of a close association between negative symptoms, the ability to anticipate pleasure and approach motivation that is evident even in healthy persons. It is suggested that the behavioral deficits immanent to negative symptoms reflect difficulties in the ability to translate emotions into motivation. © 2013 Elsevier Ireland Ltd.

Health and well-being (H&W) improve during vacation. However, it is unclear whether this general development applies to all employees, while also little is known about the underlying processes causing such an improvement. Our research questions were: (1) Does every worker experience a positive effect of vacation on H&W? and (2) Can vacation activities and experiences explain changes in H&W during vacation? In a 7-week longitudinal field study, 96 workers reported their H&W 2 weeks before, during, 1 week, 2 and 4 weeks after a winter sports vacation on 6 indicators (health status, mood, fatigue, tension, energy level and satisfaction). Sixty percent of the sample experienced substantial improvement of H&W during and after vacation. Yet, a small group experienced no (23%) or a negative effect of vacation (17%). Spending limited time on passive activities, pleasure derived from vacation activities, and the absence of negative incidents during vacation explained 38% of the variance in the vacation effect. Although vacation has a positive, longer lasting effect for many, it is not invariably positive for all employees. Choosing especially pleasant vacation activities and avoiding negative incidents as well as passive activities during active vacations apparently contributes to the positive effect of vacation on H&W.

Anxiety sensitivity (AS), defined as the extent to which individuals believe anxiety and anxiety-related sensations have harmful consequences, may play an important explanatory role in the relation between emotional non-acceptance and the expression of traumatic stress symptoms among trauma-exposed smokers. This investigation examined whether lower-order dimensions of AS (cognitive, physical, and social concerns) differentially explain the relation between emotional non-acceptance and post-traumatic stress (PTS) symptom clusters (re-experiencing, avoidance, hyperarousal) among trauma-exposed daily smokers (N = 169, 46% female; Mage = 41, SD = 12.3). AS and its lower-order facets of cognitive and social concerns were found to mediate the relations between emotional non-acceptance and avoidance and hyperarousal PTS symptoms. Using a multiple mediation model, the mediational effect of AS cognitive concerns for the relation between emotional non-acceptance and post-traumatic avoidance symptoms was found to be uniquely evident relative to social and physical concerns. All observed AS effects were evident above and beyond the variance accounted for by gender, number of traumatic event exposure types, negative affectivity, number of cigarettes smoked per day, and alcohol use problems. The present findings suggest cognitive-based AS concerns may play a mechanistic role in the relation between emotional non-acceptance and certain PTS symptoms among trauma-exposed daily smokers.

Background There is a growing interest in nomophobia, which is defined as the fear of being out of cellular phone contact, or "feelings of discomfort or anxiety experienced by individuals when they are unable to use their mobile phones or utilize the affordances these devices provide”. However, only limited research can be found in terms of its determinants at present. Contemporary literature suggests that the relationships among attachment styles, mindfulness, and nomophobia have not been investigated. Objective This study aims to investigate the mediating effect of mindfulness on the relationship between attachment and nomophobia. In addition, the study also focuses on gender differences in attachment, mindfulness, and nomophobia. A theory-based structural model was tested to understand the essentials of the associations between the constructs. Methods The Experiences in Close Relationships Scale, Nomophobia Questionnaire, and Mindful Attention Awareness Scale were used to collect data from undergraduate students (N=450; 70.9% women [319/450]; mean age=21.94 years [SD 3.61]). Two measurement models (ie, attachment and mindfulness) and a structural model were specified, estimated, and evaluated. Results The structural equation model shows that the positive direct effects of avoidant (.13, P=.03) and anxious attachment (.48, P<.001) on nomophobia were significant. The negative direct effects of avoidant (−.18, P=.01) and anxious attachment (−.33, P<.001) on mindfulness were also significant. Moreover, mindfulness has a significant negative effect on nomophobia for women only (−.13, P=.03). Finally, the Sobel test showed that the indirect effects of avoidant and anxious attachment on nomophobia via mindfulness were significant (P<.001). The direct and indirect effects of anxious attachment, avoidant attachment, and mindfulness altogether accounted for 33% of the total variance in nomophobia. Gender comparison results show that there is a significant difference in attachment based on gender (F2,447=6.97, P=.01, Wilk λ=.97, partial η2=.03). Women (mean 68.46 [SD 16.96]) scored significantly higher than men (mean 63.59 [SD 15.97]) in anxious attachment (F1=7.93, P=.01, partial η2=.02). Gender differences in mindfulness were not significant (F4,448=3.45, P=.69). On the other hand, results do show significant gender differences in nomophobia (F4,445=2.71, P=.03, Wilk λ=.98, partial η2=.02) where women scored significantly higher than men. Conclusions In general, individuals who are emotionally more dependent and crave more closeness and attention in the relationship tend to display higher levels of fear or discomfort when they have no access to their mobile phones. However, gender has a differential impact on the relationship between avoidant attachment and nomophobia. This study establishes the impact of mindfulness on nomophobia for women; therefore, future studies should test the effectiveness of mindfulness-based therapy approaches and confirm whether they are effective and efficient. On the basis of significant gender difference in nomophobia and attachment, we conclude that gender should be taken into account in mindfulness-based treatments dealing with nomophobia.

Condensing siRNA with cationic polymers is a major strategy used in the development of siRNA carriers that can avoid degradation by nucleases and achieve effective delivery of siRNA into the cytoplasm. However, ineffective release of siRNA from such condensed forms into the cytoplasm is a limiting step for induction of RNAi effects, and can be attributed to tight condensation of siRNA with the cationic polymers, due to potent electrostatic interactions. Here, we report that siRNA condensed with a slightly acidic pH-sensitive peptide (SAPSP), whose total charge is inverted from positive to negative in response to cytoplasmic pH, is effectively released via electrostatic repulsion of siRNA with negatively charged SAPSP at cytoplasmic pH (7.4). The condensed complex of siRNA and positively-charged SAPSP at acidic pH (siRNA/SAPSP) was found to result in almost complete release of siRNA upon charge inversion of SAPSP at pH 7.4, with the resultant negatively-charged SAPSP having no undesirable interactions with endogenous mRNA. Moreover, liposomes encapsulating siRNA/SAPSP demonstrated knockdown efficiencies comparable to those of commercially available siRNA carriers. Taken together, SAPSP may be very useful as a siRNA condenser, as it facilitates effective cytoplasmic release of siRNA, and subsequent induction of specific RNAi effects.Condensing siRNA with cationic polymers is a major strategy used in the development of siRNA carriers that can avoid degradation by nucleases and achieve effective delivery of siRNA into the cytoplasm.

Attentional bias for emotional information in older adults: the role of emotion and future time perspective.

2013-01-01

Research suggests that older adults display a positivity bias at the level of information processing. However, because studies investigating attentional bias for emotional information in older adults have produced mixed findings, research identifying inter-individual differences that may explain these inconsistent results is necessary. Therefore, we investigated whether mood, symptoms of depression, symptoms of anxiety and future time perspective are related to attentional bias in older adults. Thirty-seven healthy older adults and 25 healthy middle-aged adults completed questionnaires to assess mood, symptoms of depression, symptoms of anxiety and future time perspective. Attentional bias towards happy, sad and neutral information was measured using a modified exogenous cueing paradigm with long cue presentations, to measure maintained attention versus avoidance of emotional stimuli. Older adults showed attentional avoidance for all emotional faces, whereas no attentional biases were found in the middle-aged group. Moreover, in the older adult group, avoidance for negative information was related to anxiety. Future time perspective was unrelated to attentional bias. These findings suggest that anxiety may lead to inter-individual differences in attentional bias in older adults, and that avoidance from negative information may be an emotion regulation strategy.

Integrating implications from regulatory focus and approach/avoidance motivation theories, we present a framework wherein motivational orientations toward positive (approach motivation orientation) or negative (avoidance motivation orientation) stimuli interact with workplace success to mediate the relation of core self-evaluation (CSE) with job satisfaction. Using data collected from supervisor-subordinate dyads (Sample 1) and time-lagged data (Sample 2), we found that the results from two studies indicated that the interaction of workplace success and avoidance motivation orientation mediated relations of CSE with job satisfaction. Although approach motivation orientation did not interact with workplace success, it did mediate the CSE-job satisfaction relation on its own. Implications for the CSE and approach/avoidance literatures are discussed.

While comparing results on benchmark functions is a widely used practice to demonstrate the competitiveness of global optimization algorithms, fixed benchmarks can lead to a negative data mining process. To avoid this negative effect, the GENOPT contest benchmarks can be used which are based on randomized function generators, designed for scientific experiments, with fixed statistical characteristics but individual variation of the generated instances. The generators are available to participants for off-line tests and online tuning schemes, but the final competition is based on random seeds communicated in the last phase through a cooperative process. A brief presentation and discussion of the methods and results obtained in the framework of the GENOPT contest are given in this contribution.

Imagining intergroup contact can combat mental health stigma by reducing anxiety, avoidance and negative stereotyping.

Research has demonstrated widespread negative attitudes held toward people with mental health problems. Our study investigated whether a new prejudice reduction technique, imagined intergroup contact (Crisp & Turner, 2009), could combat stigma against people with mental illness, and the mediating processes through which it may exert this beneficial effect. We found that compared to a control condition, participants who imagined a positive encounter with a schizophrenic person reported weakened stereotypes and formed stronger intentions to engage in future social interactions with schizophrenic people in general. Importantly, these intentions were formed due to reduced feelings of anxiety about future interactions. We discuss the implications of these findings for improving the social inclusion of people with mental health problems.

Population properties affect inbreeding avoidance in moose

Mechanisms reducing inbreeding are thought to have evolved owing to fitness costs of breeding with close relatives. In small and isolated populations, or populations with skewed age- or sex distributions, mate choice becomes limited, and inbreeding avoidance mechanisms ineffective. We used a unique individual-based dataset on moose from a small island in Norway to assess whether inbreeding avoidance was related to population structure and size, expecting inbreeding avoidance to be greater in years with larger populations and even adult sex ratios. The probability that a potential mating event was realized was negatively related to the inbreeding coefficient of the potential offspring, with a stronger relationship in years with a higher proportion or number of males in the population. Thus, adult sex ratio and population size affect the degree of inbreeding avoidance. Consequently, conservation managers should aim for sex ratios that facilitate inbreeding avoidance, especially in small and isolated populations. PMID:25540152

Vigilance in the Laboratory Predicts Avoidance in the Real World: A Dimensional Analysis of Neural, Behavioral, and Ecological Momentary Data in Anxious Youth

Vigilance and avoidance of threat are observed in anxious adults during laboratory tasks, and are posited to have real-world clinical relevance, but data are mixed in anxious youth. We propose that vigilance-avoidance patterns will become evident in anxious youth through a focus on individual differences and real-world strategic avoidance. Decreased functional connectivity between the amygdala and prefrontal cortex (PFC) could play a mechanistic role in this link. 78 clinically anxious youth completed a dot-probe task to assess vigilance to threat while undergoing fMRI. Real-world avoidance was assessed using Ecological Momentary Assessment (EMA) of self-reported suppression and distraction during negative life events. Vigilance towards threat was positively associated with EMA distraction and suppression. Functional connectivity between a right amygdala seed region and dorsomedial and right dorsolateral PFC regions was inversely related to EMA distraction. Dorsolateral PFC-amygdalar connectivity statistically mediated the relationship between attentional vigilance and real-world distraction. Findings suggest anxious youth showing attentional vigilance toward threat are more likely to use suppression and distraction to regulate negative emotions. Reduced PFC control over limbic reactivity is a possible neural substrate of this pattern. These findings lend ecological validity to laboratory vigilance assessments and suggest PFC-amygdalar connectivity is a neural mechanism bridging laboratory and naturalistic contexts. PMID:27010577

Approaching system equilibrium with accurate or not accurate feedback information in a two-route system

With the development of intelligent transport system, advanced information feedback strategies have been developed to reduce traffic congestion and enhance the capacity. However, previous strategies provide accurate information to travelers and our simulation results show that accurate information brings negative effects, especially in delay case. Because travelers prefer to the best condition route with accurate information, and delayed information cannot reflect current traffic condition but past. Then travelers make wrong routing decisions, causing the decrease of the capacity and the increase of oscillations and the system deviating from the equilibrium. To avoid the negative effect, bounded rationality is taken into account by introducing a boundedly rational threshold BR. When difference between two routes is less than the BR, routes have equal probability to be chosen. The bounded rationality is helpful to improve the efficiency in terms of capacity, oscillation and the gap deviating from the system equilibrium.

Examining coping style and the relationship between stress and subjective well-being in Australia's 'sandwich generation'.

The sandwich generation represents adults, often in midlife, who care for both children and ageing parents/relatives. While the stress they experience has received some attention, little research has investigated the subjective well-being (SWB) of this population. This study examined the relationship between perceived stress and SWB and the moderating effect of coping style. Ninety-three participants (80 women), aged 23-63 years, completed an online survey measuring perceived stress, coping strategies, life satisfaction and positive and negative affect. Stress was negatively associated with SWB. While emotion- and problem-focused coping were directly associated with SWB outcomes, the only moderating effect found was for avoidance-focused coping (AFC). Specifically, AFC was associated with higher positive affect for those reporting lower stress. This study highlights the need to recognise the distinct circumstances that exist for the sandwich generation. Limitations and suggestions for future research are discussed. © 2017 AJA Inc.

To examine the effect of self-related factors, including self-regulation, self-esteem and self-efficacy, on decision-making styles of early adults. The cross-sectional study was conducted from February to August, 2014 at four universities of Islamabad, Pakistan, and comprised adult students of both Social and Natural sciences. Data was collected through Self-Regulation Questionnaire, Self-Esteem Scale, Self-Efficacy Scale and the General Decision Making Styles Questionnaire. Data was subjected to multivariate regression analysis. Of the 300 participants, 160(53%) were men and 140(47%) were women. The overall mean age was 22.68±5.96 years. Besides, 170(56%) were studying Social sciences and 130(44%) Natural sciences. Self-regulation, self-esteem and self-efficacy positively predicted rational and intuitive style and negatively predicted avoidant and spontaneous style. Self-efficacy and self-regulation negatively predicted dependent style. Ensuring positive self-related factors affected adults' effective decision-making choices.

Do distress responses to a traumatic film predict susceptibility to the misinformation effect?

2013-01-01

The misinformation effect is defined as an impairment in memory for past events due to exposure to misleading information (E. F. Loftus, 2005 ). Some people may be more susceptible to the misinformation effect than others, and this may also depend on their response to a distressing event. The purpose of the current study was to investigate several key factors that may contribute to misinformation susceptibility for distressing events, namely posttraumatic stress disorder symptoms such as avoidance, intrusions, and dissociation. Participants watched either a neutral or trauma film, rated their level of distress, and completed measures of trait and state dissociation. When participants returned a week later, misinformation was introduced via an eyewitness statement and free recall was assessed. Findings indicated that dissociation was related to higher distress ratings following the film but was not related to acceptance of misinformation. However, avoidance scores were related to increased recall of misinformation items, and reported experiences of intrusions were related to greater accuracy. These results are discussed in light of the paradoxical negative emotion hypothesis.

Parental warmth amplifies the negative effect of parental hostility on dating violence.

PubMed

2012-09-01

Past research has documented the positive association between parental hostility and offspring involvement in intimate partner violence. Researchers, practitioners, and parents typically adopt the standpoint that parental warmth may counter these negative lessons. However, Straus and colleagues argue that parents foster IPV to the extent that they teach their child that verbal and physical aggression are a normal and legitimate component of loving relationships. A strict interpretation of social learning theory would suggest that these lessons are more, not less, likely to occur when parental hostility is interspersed with displays of affection. The present study tests this idea using data from 2,088 undergraduate students from a large university in the Southeast. Consistent with Straus' arguments, findings suggest that, rather than attenuating the negative effects of hostility, supportive interactions seem to amplify the probability that offspring will emulate aggressive behaviors in their own romantic relationships. The same is true for the effects of harsh parenting for women. It seems that the best way parents can avoid contributing to their child's chances of being in a violent dating relationship is to eschew family interaction involving verbal and physical aggression.

Personality traits as risk factors of depression and anxiety among Japanese students.

The aim of this study is to examine the effects of personality (temperament and character) on specific depression and specific anxiety. A total of 541 Japanese undergraduates were investigated by using the Temperament and Character Inventory (TCI) and the Hospital Anxiety and Depression (HAD) scale. Hierarchical multiple regression analyses demonstrated that specific depression was predicted by lower Reward-Dependence, Persistence, Self-Directedness, Cooperativeness, and Self-Transcendence; specific anxiety was predicted by higher Novelty-Seeking, Harm-Avoidance, Persistence, and Self-Transcendence, and lower Self-Directedness. Immaturity of Self-Directedness is a risk factor for negative affectivity. Immaturity of all character dimensions is a risk factor for specific depression. The relationship between Harm-Avoidance and depression in previous studies may be linked partly to somatic symptoms that were deliberately eliminated in the HAD scale.

Underwater strobe lights can influence the behavior and distribution of fishes and are increasingly used as a technique to divert fish away from water intake structures on dams. However, few studies examine how strobe lights may affect organisms other than targeted species. To gain insight on strobe lighting effects on nontarget invertebrates, we investigated whether underwater strobe lights influence zooplankton distributions and abundance in Lake Oahe, South Dakota. Zooplankton were collected using vertical tows at 3 discrete distances from an underwater strobe light to quantify the influence of light intensity on zooplankton density. Samples were collected from 3 different depth ranges (0–10 m, 10–20 m and 20–30 m) at <1 m, 15 m and ⩾100 m distance intervals away from the strobe light. Copepods represented 67.2% and Daphnia spp. represented 23.3% of all zooplankton sampled from 17 August to 15 September 2004. Night time zooplankton densities significantly decreased in surface waters when strobe lights were activated. Copepods exhibited the greatest avoidance patterns, while Daphnia avoidance varied throughout sampling depths. These results indicate that zooplankton display negative phototaxic behavior to strobe lights and that researchers must be cognizant of potential effects to the ecosystem such as altering predator–prey interactions or affecting zooplankton distribution and growth.

This study explored the relations between use of the social networking site Facebook and scores on affinity-seeking, social loneliness, and social avoidance by 313 college students. Social loneliness and social avoidance, but not affinity-seeking, were positively and statistically significantly related to time spent using Facebook. The number of close Facebook friends was negatively and statistically significantly related to social loneliness and social avoidance. Women perceived Facebook as a more integral part of daily interactions than did men. 38% of the 283 Facebook members indicated their accounts contained information and/or a picture that could embarrass them, with men having significantly more embarrassing content than women. The findings are discussed within the context of social compensation.

The influence of personality traits on smokers' affect, withdrawal and cessation intervention outcome.

The personality traits of harm avoidance (HA), novelty seeking (NS), and reward dependence (RD), as measured by the Tridimensional Personality Questionnaire (TPQ), have been linked to smoking behavior. The extent to which these traits are associated with smoking withdrawal and cessation outcome is unclear. We sought to address this question among 131 treatment-seeking smokers who were randomly assigned to either a smoking cessation treatment (four 30-min behavioral counseling sessions) or a control condition. We found that HA was positively associated with baseline depressive symptoms, baseline negative affect, and post-quit withdrawal, and negatively associated with positive affect at both baseline and post-quit. Additionally, we found that smokers with higher HA scores were more likely to be abstinent. NS was negatively associated with post-quit positive affect and positively associated with post-quit negative affect and withdrawal. RD was not found to be related to any outcome measures. Our findings suggest that, despite experiencing greater baseline and post-quit negative affect, smokers higher in trait harm avoidance are more likely to quit smoking. The treatment and theoretical ramifications of these findings are discussed. Copyright © 2015 Elsevier Ltd. All rights reserved.

Negative Attitudes toward Older Workers and Hiring Decisions: Testing the Moderating Role of Decision Makers' Core Self-Evaluations.

PubMed

Fasbender, Ulrike; Wang, Mo

2016-01-01

Organizational hiring practices have been charged for unfair treatment on the grounds of age. Drawing on theories of planned behavior and core self-evaluations, this research investigated the impact of negative attitudes toward older workers on hiring decisions and examined the moderating role of decision-makers' core self-evaluations. We tested our hypotheses based on a structured online questionnaire and a vignette study using a sample of 102 participants working in human resource management across different industries. As predicted, negative attitudes toward older workers were positively related to avoidance of hiring older people, which in turn was negatively related to the likelihood to select the oldest candidate. Because hiring decisions are not only about the hiring subject but also about the decision-maker, we tested the moderating role of decision-makers' core self-evaluations. Results showed that core self-evaluations buffered the relationship between negative attitudes toward older workers and avoidance of hiring older people. Theoretical implications of the findings with regard to hiring decisions about older people and practical recommendations to improve diversity management strategies and age-balanced hiring practices in organizations are discussed.

Looking on the bright side: biased attention and the human serotonin transporter gene.

Fox, Elaine; Ridgewell, Anna; Ashwin, Chris

Humans differ in terms of biased attention for emotional stimuli and these biases can confer differential resilience and vulnerability to emotional disorders. Selective processing of positive emotional information, for example, is associated with enhanced sociability and well-being while a bias for negative material is associated with neuroticism and anxiety. A tendency to selectively avoid negative material might also be associated with mental health and well-being. The neurobiological mechanisms underlying these cognitive phenotypes are currently unknown. Here we show for the first time that allelic variation in the promotor region of the serotonin transporter gene (5-HTTLPR) is associated with differential biases for positive and negative affective pictures. Individuals homozygous for the long allele (LL) showed a marked bias to selectively process positive affective material alongside selective avoidance of negative affective material. This potentially protective pattern was absent among individuals carrying the short allele (S or SL). Thus, allelic variation on a common genetic polymorphism was associated with the tendency to selectively process positive or negative information. The current study is important in demonstrating a genotype-related alteration in a well-established processing bias, which is a known risk factor in determining both resilience and vulnerability to emotional disorders.

Gender, gender roles, and anxiety: perceived confirmability of self report, behavioral avoidance, and physiological reactivity.

Despite the well-documented gender effect in anxiety, less is known about contributing factors to women's greater risk for anxiety and fears. The present study examined the relationship between gender, gender role orientation (i.e., expressivity/instrumentality) and fear of harmless insects (tarantula), using a multimodal approach of self-report measures, a Behavioral Approach Test (BAT), and physiological reactivity. Participants (144 college students; 67 women, 77 men) completed a questionnaire packet and then were instructed to approach a tarantula. We were unable to replicate Pierce and Kirkpatrick's (1992) findings that men underreport anxiety. Consistent with the literature, women in the study experienced greater anxiety and avoidance compared to men. However, men and women did not differ on physiological reactivity during the first 2 min of the BAT. The concordance across avoidance, anxiety and heart rate reactivity differed by gender, suggesting that men and women have different experiences when faced with a fearful object. Furthermore, instrumentality (masculinity) was negatively related to anticipatory anxiety for women but not for men. Copyright © 2011 Elsevier Ltd. All rights reserved.

Female crickets assess relatedness during mate guarding and bias storage of sperm towards unrelated males.

Tuni, C; Beveridge, M; Simmons, L W

2013-06-01

Recent evidence shows that females exert a post-copulatory fertilization bias in favour of unrelated males to avoid the genetic incompatibilities derived from inbreeding. One of the mechanisms suggested for fertilization biases in insects is female control over transport of sperm to the sperm-storage organs. We investigated post-copulatory inbreeding-avoidance mechanisms in females of the cricket Teleogryllus oceanicus. We assessed the relative contribution of related and unrelated males to the sperm stores of double-mated females. To demonstrate unequivocally that biased sperm storage results from female control rather than cryptic male choice, we manipulated the relatedness of mated males and of males performing post-copulatory mate guarding. Our results show that when guarded by a related male, females store less sperm from their actual mate, irrespective of the relatedness of the mating male. Our data support the notion that inhibition of sperm storage by female crickets can act as a form of cryptic female choice to avoid the severe negative effects of inbreeding. © 2013 The Authors.

Yazdi, Seyedeh-Monavar; Hosseinian, Simin; Eslami, Mansoure; Fathi-Ashtiani, Ali

This study aims to find the relationship between quality of life and coping strategies in coronary heart disease patients. Two hundred coronary heart disease patients at Tehran Heart Center, who had been diagnosed with the disease 3 months before, were selected and filled out The Coping Inventory for Stressful Situations (CISS) and Quality of Life-SF36. Results showed a discrepancy between quality of life indices and coping strategies. Task-oriented strategy had a positive and significant relationship with total quality of life and PF indices while it had a negative and significant relationship with MH, RE and RP indices. Emotional-oriented strategy had a positive and significant relationship with RP and RE indices while it had a negative and significant relationship with PF, GH, PH, total psychological health and total quality of life indices. Avoidance-oriented strategy had a negative and significant relationship only with MH index. Furthermore, quality of life aspects (physical and psychological) had a positive and significant relationship with emotional-oriented strategy, but it did not have a significant relationship with task-oriented and avoidance-oriented strategies. Also, the social aspect of quality of life did not have a significant relationship with any of the strategies. Considering the effect of stress on decreasing the quality of life, we recommend a psychologist train coping strategies to coronary heart disease patients along with medical treatments in order to improve recovery, maintain health and reduce recurrence.

In this paper, Bayesian Binary Sensing (BBS) is discussed as an effective tool for Bayesian Inference (BI) evaluation in interdisciplinary areas such as ISR (and, C3I), Homeland Security, QC, medicine, defense, and many others. In particular, Hilbertian Sine (HS) as an absolute measure of BI, is introduced, while avoiding relativity of decision threshold identification, as in the case of traditional measures of BI, related to false positives and false negatives.

Is all motivation good for learning? Dissociable influences of approach and avoidance motivation in declarative memory

The present study investigated the effects of approach versus avoidance motivation on declarative learning. Human participants navigated a virtual reality version of the Morris water task, a classic spatial memory paradigm, adapted to permit the experimental manipulation of motivation during learning. During this task, participants were instructed to navigate to correct platforms while avoiding incorrect platforms. To manipulate motivational states participants were either rewarded for navigating to correct locations (approach) or punished for navigating to incorrect platforms (avoidance). Participants’ skin conductance levels (SCLs) were recorded during navigation to investigate the role of physiological arousal in motivated learning. Behavioral results revealed that, overall, approach motivation enhanced and avoidance motivation impaired memory performance compared to nonmotivated spatial learning. This advantage was evident across several performance indices, including accuracy, learning rate, path length, and proximity to platform locations during probe trials. SCL analysis revealed three key findings. First, within subjects, arousal interacted with approach motivation, such that high arousal on a given trial was associated with performance deficits. In addition, across subjects, high arousal negated or reversed the benefits of approach motivation. Finally, low-performing, highly aroused participants showed SCL responses similar to those of avoidance–motivation participants, suggesting that for these individuals, opportunities for reward may evoke states of learning similar to those typically evoked by threats of punishment. These results provide a novel characterization of how approach and avoidance motivation influence declarative memory and indicate a critical and selective role for arousal in determining how reinforcement influences goal-oriented learning.

Bioturbation from earthworm's activity contributes to soil creep and soil carbon dynamics, and provide enough aeration conditions for agricultural practices all over the world. In developing countries where there is a long term misuse of pesticides for agricultural purposes, lost of these benefits from earthworms activity might already yielded negative effects in the current crop production. Little research has been performed on earthworms avoidance to pesticides in developing countries located in the tropics. Furthermore, the complete avoidance reaction (from attraction to 100% avoidance) from earthworms to most of the pesticides used in potato cultivation in developing countries like Colombia is incomplete as yet. Hence the aim of this study is to assess the lost of earthworm on the soils caused by different concentrations of pesticides and associated agricultural impacts caused by a lost in the soil bioturbation. As a first stage, we have studied earthworm's avoidance to pesticide concentration in a potato agricultural area located in Colombia. Local cultivated Eisenia fetida were exposed to four of the most frequent applied active ingredients in potato crops i.e. carbofuran, mancozeb, methamidophos and chlorpyriphos. Adult earthworm toxicity experiments were carried out in two soils, untreated grasslands under standard (ISO guidelines) and undisturbed conditions, and exposed to six different concentrations of the active ingredients. The results of the avoidance reaction on the standard soils were significant for carbofuran, mancoceb and chlorpyrifos. For each of the three active ingredients, we found i) overuse of pesticide, ii) applied dose of carbofuran, mancoceb and chlorpyrifos by the farmers potentially caused 20%, 11% and 9% of earthworms avoidance on the cultivated soils, respectively.

Background. The revised Temperament and Character Inventory (TCI-R) measures Cloninger's psychobiological model of personality. The average effects of individual temperament and character traits have been associated with schizotypy and with impaired regulation of affect and cognition. We extended prior research by testing predictions about the association of specific multidimensional configurations of temperament and character traits on schizotypy, affect balance, and self-perceived cognitive functioning. Method. A well-educated sample of native Greeks (N = 483), completed a new Greek translation of the TCI-R, as well as the Schizotypal Personality Questionnaire (SPQ), the Positive/Negative Affect Schedule (PANAS) and the Cognitive Failures Questionnaire (CFQ). The factor structure of the TCI-R was examined with exploratory and confirmatory tests. Associations between reported measures were examined with correlational and regression analyses. Results. The TCI-R had good psychometric properties as expected from studies in other countries. As predicted, specific configurations of temperament and character were associated with schizotypy, negative affect balance, and cognitive lapses. The "Borderline/Explosive temperament" (high Novelty Seeking, high Harm Avoidance, low Reward Dependence), "Schizotypal/Disorganized character" (low Self-directedness, low Cooperativeness, high Self-transcendence), and "Low Ego Strength/Fragile" profile (high Harm Avoidance, low Persistence, low Self-Directedness) were each strongly associated with higher stereotypy, negative affect balance (low positive affect and high negative affect), and subjective cognitive lapses compared to their contrast groups. Discussion. Multidimensional TCI profiles are strongly related to individual differences in schizotypy and self-reported regulation of affect and cognition. The Greek translation of the TCI-R is psychometrically sound and useful for clinical assessment and research.

The “eye avoidance” hypothesis of autism face processing

Tanaka, James W.; Sung, Andrew

2013-01-01

Although a growing body of research indicates that children with autism spectrum disorder (ASD) exhibit selective deficits in their ability to recognize facial identities and expressions, the source of their face impairment is, as yet, undetermined. In this paper, we consider three possible accounts of the autism face deficit: 1) the holistic hypothesis, 2) the local perceptual bias hypothesis and 3) the eye avoidance hypothesis. A review of the literature indicates that contrary to the holistic hypothesis, there is little evidence to suggest that individuals with autism do not perceive faces holistically. The local perceptual bias account also fails to explain the selective advantage that ASD individuals demonstrate for objects and their selective disadvantage for faces. The eye avoidance hypothesis provides a plausible explanation of face recognition deficits where individuals with ASD avoid the eye region because it is perceived as socially threatening. Direct eye contact elicits a heightened physiological response as indicated by heightened skin conductance and increased amgydala activity. For individuals with autism, avoiding the eyes is an adaptive strategy, however, this approach interferes with the ability to process facial cues of identity, expressions and intentions, The “eye avoidance” strategy has negative effects on the ability to decode facial information about identity, expression, and intentions, exacerbating the social challenges for persons with ASD.

The present study examined self-regulatory and goal-conflicting processes in the avoidance of drunk driving among Greek young drivers. A total of 361 university students in Greece completed a questionnaire, using a retrospective cross-sectional survey design. One-third reported to have driven under the influence of alcohol. Although prior intentions were clearly related to actual avoidance of drunk driving, one out of five respondents had not complied with their intention. An examination of post-intentional correlates of avoidance of drunk driving among positive intenders showed that avoidance of drunk driving was positively related to alcohol limitation plans and alcohol limitation self-efficacy, whereas negative relations were found for goal conflict and behavioural willingness. The present study suggests that people should not only be motivated but also be equipped with self-regulatory strategies aiming at the avoidance of drinking. Finally, goal commitment should be enhanced by increasing the salience of the avoidance goal.

Latent constructs model explaining the attachment-linked variation in autobiographical remembering.

PubMed

Öner, Sezin; Gülgöz, Sami

2016-01-01

In the current study, we proposed a latent constructs model to characterise the qualitative aspects of autobiographical remembering and investigated the structural relations in the model that may vary across individuals. Primarily, we focused on the memories of romantic relationships and argued that attachment anxiety and avoidance would be reflected in the ways that individuals encode, rehearse, or remember autobiographical memories in close relationships. Participants reported two positive and two negative relationship-specific memories and rated the characteristics for each memory. As predicted, the basic memory model yielded appropriate fit, indicating that event characteristics (EC) predicted the frequency of rehearsal (RC) and phenomenology at retrieval (PC). When attachment variables were integrated, the model showed that rehearsal mediated the link between anxiety and PC, especially for negative memories. On the other hand, for avoidance EC was the key factor mediating the link between avoidance and RC, as well as PC. Findings were discussed with respect to autobiographical memory functions emphasising a systematically, integrated framework.

The relationships between psychological mindedness, parental bonding and adult attachment.

The aims of this study were to clarify the relationship between psychological mindedness and attachment relationships in childhood and adulthood. This analogue study examined associations between psychological mindedness and attachment using a cross-sectional design. Participants completed questionnaire measures of psychological mindedness, parental bonding, and adulthood attachment relationships. As hypothesized, psychological mindedness was strongly, negatively correlated with attachment avoidance in adulthood. Psychological mindedness was also positively correlated with perceived maternal care in childhood, and negatively correlated with perceived paternal over-protection. However, a regression analysis found that attachment avoidance in adulthood was a more significant predictor of psychological mindedness than parental bonding experiences in childhood. Further research is needed to replicate associations between attachment and psychological mindedness in clinical samples and to explore additional constructs which influence psychological mindedness. High attachment avoidance may be a potential risk factor for poor psychological mindedness. Helping individuals to develop more secure attachments in their adult relationships may improve their psychological mindedness. © 2013 The British Psychological Society.

Personality traits and achievement motives: theoretical and empirical relations between the NEO Personality Inventory-Revised and the Achievement Motives Scale.

Diseth, Age; Martinsen, Øyvind

2009-04-01

Theoretical and empirical relations between personality traits and motive dispositions were investigated by comparing scores of 315 undergraduate psychology students on the NEO Personality Inventory-Revised and the Achievement Motives Scale. Analyses showed all NEO Personality Inventory-Revised factors except agreeableness were significantly correlated with the motive for success and the motive to avoid failure. A structural equation model showed that motive for success was predicted by Extraversion, Openness, Conscientiousness, and Neuroticism (negative relation), and motive to avoid failure was predicted by Neuroticism and Openness (negative relation). Although both achievement motives were predicted by several personality factors, motive for success was most strongly predicted by Openness, and motive to avoid failure was most strongly predicted by neuroticism. These findings extended previous research on the relations of personality traits and achievement motives and provided a basis for the discussion of motive dispositions in personality. The results also added to the construct validity of the Achievement Motives Scale.

In the present study an adult attachment dimension, latent to the constructs of security, anxiety, and avoidance, was hypothesized, wherein security was expected to occupy the most relevant position. Furthermore, the reciprocal functioning of attachment constructs and their interactions with self-esteem were explored. Four hundreds and thirty-four Italian university students responded to two adult attachment questionnaires (Attachment Style Questionnaire and Adult Attachment Questionnaire) and to the Rosenberg Self-esteem scale. A Many-Facet Rasch Measurement modeling approach was adopted. The main results can be summarized as follows: (a) security, anxiety, and avoidance are nested under one latent attachment dimension; (b) security occupies the most prominent position on the dimension; (c) security is positively associated with a moderate level of attachment anxiety and negatively related to avoidance; and (d) a positive interaction between self-esteem and security, and a negative relation between self-esteem and anxiety, were detected. Theoretical, clinical, and empirical implications of the results are further discussed. © 2013 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

Stereotype threat's effect on women's achievement in chemistry: The interaction of achievement goal orientation for women in science majors

NASA Astrophysics Data System (ADS)

Conway-Klaassen, Janice Marjorie

"Stereotype threat is being at risk of confirming, as a self-characteristic, a negative stereotype about one's group" (C. M. Steele & Aronson, 1995, p. 797). A stereotype threat effect then is described as the detrimental impact on a person's performance or achievement measurements when they are placed in a stereotype threat environment. For women, the negative stereotype that exists in our culture states that women are typically not as capable as men in mathematics or science subjects. This study specifically explored the potential impact of stereotype threat on women who have chosen a science-based college major. They were tested in the domain of chemistry, which is related to mathematics and often involves high level of mathematics skills. I attempted to generate a stereotype threat in the participants through describing a chemistry challenge exam as either one that had consistently shown a gender bias against women and to create a nullification effect by describing the exam as one that had shown no gender bias in the past. In the third experimental condition acting as a control, participants received only generic instructions related to taking the test itself. The second part of this study investigated whether stereotype threat effects could impact women's achievement goal orientations. In previous studies performance avoidance goal orientations have been associated with individuals placed in a stereotype threat environment. The findings on the stereotype threat effect were not significant for the chemistry challenge test achievement scores. This may be due to several factors. One factor may be the design of the chemistry challenge test and the instructions for the test. The other factor may be the women in this study. As individuals who have chosen a science based major, they may have developed coping skills and strategies that reduced the impact of a stereotype threat. It is also possible that the testing environment itself generated an implicit stereotype type threat effect which reduced the differences among the experimental conditions. However, there were significant findings related to the participants' achievement goal orientations. Individuals in the stereotype threat condition displayed higher levels of performance avoidance, overall performance, and overall avoidance goal orientations consistent with the existing literature. Post-hoc open-ended questionnaires revealed that most participants believed that men and women were equally capable in mathematics and sciences but that they also had an awareness of the negative stereotype against women in mathematics and sciences among the public. This study supports the demonstration of stereotype threat effects on women who are enrolled in science based college majors. Although I was not able to create a stereotype threat effect on their chemistry challenge test scores, I was able to demonstrate an effect on their achievement goal orientations, which has implications for instructional design and standardized testing.

Avoiding axillary lymph node dissection (ALND) for invasive breast cancers with isolated tumor cells or micrometastatic sentinel node biopsy (SNB) could decrease morbidity with minimal clinical significance. The aim of this study is to simulate the medico-economic impact of the routine use of the MSKCC non-sentinel node (NSN) prediction nomogram for ER+ HER2- breast cancer patients. We studied 1036 ER+ HER2- breast cancer patients with a metastatic SNB. All had a complementary ALND. For each patient, we calculated the probability of the NSN positivity using the MSKCC nomogram. After validation of this nomogram in the population, we described how the patients' characteristics spread as the threshold value changed. Then, we performed an economic simulation study to estimate the total cost of caring for patients treated according to the MSKCC predictive nomogram results. A 0.3 threshold discriminate the type of sentinel node (SN) metastases: 98.8% of patients with pN0(i+) and 91.6% of patients with pN1(mic) had a MSKCC score under 0.3 (false negative rate = 6.4%). If we use the 0.3 threshold for economic simulation, 43% of ALND could be avoided, reducing the costs of caring by 1 051 980 EUROS among the 1036 patients. We demonstrated the cost-effectiveness of using the MSKCC NSN prediction nomogram by avoiding ALND for the pN0(i+) or pN1(mic) ER+ HER2- breast cancer patients with a MSKCC score of less than or equal to 0.3.

2018-05-01

Many studies have investigated public reactions to nuclear accidents. However, few studies focused on more common events when a serious accident could have happened but did not. This study evaluated public response (emotional, cognitive, and behavioral) over three phases of a near-miss nuclear accident. Simulating a loss-of-coolant accident (LOCA) scenario, we manipulated (1) attribution for the initial cause of the incident (software failure vs. cyber terrorist attack vs. earthquake), (2) attribution for halting the incident (fail-safe system design vs. an intervention by an individual expert vs. a chance coincidence), and (3) level of uncertainty (certain vs. uncertain) about risk of a future radiation leak after the LOCA is halted. A total of 773 respondents were sampled using a 3 × 3 × 2 between-subjects design. Results from both MANCOVA and structural equation modeling (SEM) indicate that respondents experienced more negative affect, perceived more risk, and expressed more avoidance behavioral intention when the near-miss event was initiated by an external attributed source (e.g., earthquake) compared to an internally attributed source (e.g., software failure). Similarly, respondents also indicated greater negative affect, perceived risk, and avoidance behavioral intentions when the future impact of the near-miss incident on people and the environment remained uncertain. Results from SEM analyses also suggested that negative affect predicted risk perception, and both predicted avoidance behavior. Affect, risk perception, and avoidance behavior demonstrated high stability (i.e., reliability) from one phase to the next. © 2017 Society for Risk Analysis.

Self-esteem and other-esteem in college students with borderline and avoidant personality disorder features: An experimental vignette study.

2013-11-01

An experimental study investigated self-esteem and other-esteem responses to either fully supportive or less supportive interpersonal feedback in college students with avoidant and borderline personality disorder features (APD and BPD respectively). Disturbances in self-esteem and in evaluations of others are central to definitions of both APD and BPD, but the extent to which such interpersonal appraisals are responsive to contextual features, such as evaluative feedback from others, is not yet clear. In theory, we would expect that individuals with pronounced PD features would show more inflexible and more negative self-evaluations and others- evaluations than those without PD features. In this study with 169 undergraduates, APD but not BPD features were associated with other-contingent state self-esteem and other-esteem. A significant interaction indicated that highly avoidant respondents felt particularly negatively about themselves and their close others in situations that conveyed subtle criticism but not in situations signalling unequivocal support. This suggests that their self-esteem and other-esteem, rather than being rigidly negative, are instead highly contingent upon interpersonal feedback. Such context contingency has implications for the trait-like description of diagnostic characteristics within current taxonomies and is in line with contemporary dynamic models of personality structure and process.

Avoidance of an electric field by insects: Fundamental biological phenomenon for an electrostatic pest-exclusion strategy

Matsuda, Y.; Nonomura, T.; Kakutani, K.; Kimbara, J.; Osamura, K.; Kusakari, S.; Toyoda, H.

An electric field screen is a physical device used to exclude pest insects from greenhouses and warehouses to protect crop production and storage. The screen consists of iron insulated conductor wires (ICWs) arrayed in parallel and linked to each other, an electrostatic DC voltage generator used to supply a negative charge to the ICWs, and an earthed stainless net placed on one side of the ICW layer. The ICW was negatively charged to polarize the earthed net to create a positive charge on the ICW side surface, and an electric field formed between the opposite charges of the ICW and earthed net. The current study focused on the ability of the screen to repel insects reaching the screen net. This repulsion was a result of the insect's behaviour, i.e., the insects were deterred from entering the electric field of the screen. In fact, when the screen was negatively charged with the appropriate voltages, the insects placed their antennae inside the screen and then flew away without entering. Obviously, the insects recognized the electric field using their antennae and thereby avoided entering. Using a wide range of insects and spiders belonging to different taxonomic groups, we confirmed that the avoidance response to the electric field was common in these animals.

2017-01-01

Disclosure of a sexual or gender minority status has been associated with both positive and negative effects on wellbeing. Few studies have explored the disclosure and concealment process in young people. Interviews were conducted with 10 sexual and/or gender minority individuals, aged 18–22 years, of male birth sex. Data were analyzed qualitatively, yielding determinants and effects of disclosure and concealment. Determinants of disclosure included holding positive attitudes about one’s identity and an implicit devaluation of acceptance by society. Coming out was shown to have both positive and negative effects on communication and social support, and was associated with both increases and decreases in experiences of stigma. Determinants of concealment included lack of comfort with one’s identity and various motivations to avoid discrimination. Concealment was also related to hypervigilance and unique strategies of accessing social support. Results are discussed in light of their clinical implications. PMID:27633070

Detecting Negative Obstacles by Use of Radar

NASA Technical Reports Server (NTRS)

Mittskus, Anthony; Lux, James

2006-01-01

Robotic land vehicles would be equipped with small radar systems to detect negative obstacles, according to a proposal. The term "negative obstacles" denotes holes, ditches, and any other terrain features characterized by abrupt steep downslopes that could be hazardous for vehicles. Video cameras and other optically based obstacle-avoidance sensors now installed on some robotic vehicles cannot detect obstacles under adverse lighting conditions. Even under favorable lighting conditions, they cannot detect negative obstacles. A radar system according to the proposal would be of the frequency-modulation/ continuous-wave (FM/CW) type. It would be installed on a vehicle, facing forward, possibly with a downward slant of the main lobe(s) of the radar beam(s) (see figure). It would utilize one or more wavelength(s) of the order of centimeters. Because such wavelengths are comparable to the characteristic dimensions of terrain features associated with negative hazards, a significant amount of diffraction would occur at such features. In effect, the diffraction would afford a limited ability to see corners and to see around corners. Hence, the system might utilize diffraction to detect corners associated with negative obstacles. At the time of reporting the information for this article, preliminary analyses of diffraction at simple negative obstacles had been performed, but an explicit description of how the system would utilize diffraction was not available.

Instrumental learning paradigms are rarely employed to investigate the mechanisms underlying acquired fear responses in social anxiety. Here, we adapted a probabilistic category learning paradigm to assess information processing biases as a function of the degree of social anxiety traits in a sample of healthy individuals without a diagnosis of social phobia. Participants were presented with three pairs of neutral faces with differing probabilistic accuracy contingencies (A/B: 80/20, C/D: 70/30, E/F: 60/40). Upon making their choice, negative and positive feedback was conveyed using angry and happy faces, respectively. The highly socially anxious group showed a strong tendency to be more accurate at learning the probability contingency associated with the most ambiguous stimulus pair (E/F: 60/40). Moreover, when pairing the most positively reinforced stimulus or the most negatively reinforced stimulus with all the other stimuli in a test phase, the highly socially anxious group avoided the most negatively reinforced stimulus significantly more than the control group. The results are discussed with reference to avoidance learning and hypersensitivity to negative socially evaluative information associated with social anxiety. PMID:26347685

The present study aimed to (a) demonstrate the effect of positive-negative framing on experienced criminal justice decision makers, (b) examine the debiasing effect of visually structured risk messages, and (c) investigate whether risk perceptions mediate the debiasing effect of visual aids on decision making. In two phases, 60 senior police officers estimated the accuracy of a counterterrorism technique in identifying whether a known terror suspect poses an imminent danger and decided whether they would recommend the technique to policy makers. Officers also rated their confidence in this recommendation. When information about the effectiveness of the counterterrorism technique was presented in a numerical format, officers' perceptions of accuracy and recommendation decisions were susceptible to the framing effect: The technique was perceived to be more accurate and was more likely to be recommended when its effectiveness was presented in a positive than in a negative frame. However, when the information was represented visually using icon arrays, there were no such framing effects. Finally, perceptions of accuracy mediated the debiasing effect of visual aids on recommendation decisions. We offer potential explanations for the debiasing effect of visual aids and implications for communicating risk to experienced, professional decision makers.

The Exercise–Affect–Adherence Pathway: An Evolutionary Perspective

The low rates of regular exercise and overall physical activity (PA) in the general population represent a significant public health challenge. Previous research suggests that, for many people, exercise leads to a negative affective response and, in turn, reduced likelihood of future exercise. The purpose of this paper is to examine this exercise–affect–adherence relationship from an evolutionary perspective. Specifically, we argue that low rates of physical exercise in the general population are a function of the evolved human tendency to avoid unnecessary physical exertion. This innate tendency evolved because it allowed our evolutionary ancestors to conserve energy for physical activities that had immediate adaptive utility such as pursuing prey, escaping predators, and engaging in social and reproductive behaviors. The commonly observed negative affective response to exercise is an evolved proximate psychological mechanism through which humans avoid unnecessary energy expenditure. The fact that the human tendencies toward negative affective response to and avoidance of unnecessary physical activities are innate does not mean that they are unchangeable. Indeed, it is only because of human-engineered changes in our environmental conditions (i.e., it is no longer necessary for us to work for our food) that our predisposition to avoid unnecessary physical exertion has become a liability. Thus, it is well within our capabilities to reengineer our environments to once again make PA necessary or, at least, to serve an immediate functional purpose. We propose a two-pronged approach to PA promotion based on this evolutionary functional perspective: first, to promote exercise and other physical activities that are perceived to have an immediate purpose, and second, to instill greater perceived purpose for a wider range of physical activities. We posit that these strategies are more likely to result in more positive (or less negative) affective responses to exercise, better adherence to exercise programs, and higher rates of overall PA.

Social approach and social avoidance goals (i.e., approach of positive and avoidance of negative outcomes in social situations) are important predictors of the feeling of being socially integrated or isolated. However, little is known about the development of these goals across adulthood. In a large diary study with N = 744 young (18-39 years),…
