It has recently been suggested that individual differences in Reward Sensitivity and Punishment Sensitivity may determine how children respond to food. These temperamental traits reflect activity in two basic brain systems that respond to rewarding and punishing stimuli, respectively, with approach and avoidance. Via parent-report questionnaires, we investigate the associations of the general motivational temperamental traits Reward Sensitivity and Punishment Sensitivity with Food Approach and Food Avoidance in 98 preschool children. Consistent with the conceptualization of Reward Sensitivity in terms of approach behavior and Punishment Sensitivity in terms of avoidance behavior, Reward Sensitivity was positively related to Food Approach, while Punishment Sensitivity was positively related to Food Avoidance. Future research should integrate these perspectives (i.e., general temperamental traits Reward Sensitivity and Punishment Sensitivity, and Food Approach and Avoidance) to get a better understanding of eating behavior and related body weight.

The differential susceptibility hypothesis suggests that children's innate characteristics and their rearing experiences interact differentially during development. Recently, the study of interactions between infants' temperament and rearing experiences has become a research hotspot. In China, grandparental care is a very common phenomenon, with many infants taken care of by grandparents while mothers are out for work. To investigate whether the associations between maternal and grandmaternal sensitivity, and behavior problems were moderated by infant temperamental reactivity, while the infants were raised by both their mothers and grandmothers. A total of 71 infants (average age of 17.6months), their mothers and grandmothers were included in this study. Maternal sensitivity and grandmaternal sensitivity were assessed with the Maternal Behavior Q-sort-Chinese Version, infants' temperamental reactivity was measured with Carey's Toddler Temperament Questionnaire-Chinese Revision, and infants' behavior problems were measured with the Infant-Toddler Social and Emotional Assessment-Chinese Version. Maternal sensitivity significantly predicted infants' impulsivity and aggression. Infants' temperamental reactivity moderated the effect of maternal sensitivity on infants' general anxiety. In addition, infant temperamental reactivity moderated the impact of grandmaternal sensitivity on infants' separation distress. Our results support the differential susceptibility hypothesis to some extent. Infants with high temperamental reactivity not only suffer more from low maternal and grandmaternal sensitivity, but also benefit more from high maternal and grandmaternal sensitivity as compared to those infants with low temperamental reactivity.

The experience of emotions and their cognitive control are based upon neural responses in prefrontal and subcortical regions and could be affected by personality and temperamental traits. Previous studies established an association between activity in reappraisal-related brain regions (e.g., inferior frontal gyrus and amygdala) and emotion regulation success. Given these relationships, we aimed to further elucidate how individual differences in emotion regulation skills relate to brain activity within the emotion regulation network on the one hand, and personality/temperamental traits on the other. We directly examined the relationship between personality and temperamental traits, emotion regulation success and its underlying neuronal network in a large sample (N = 82) using an explicit emotion regulation task and functional MRI (fMRI). We applied a multimethodological analysis approach, combing standard activation-based analyses with structural equation modeling. First, we found that successful downregulation is predicted by activity in key regions related to emotion processing. Second, the individual ability to successfully upregulate emotions is strongly associated with the ability to identify feelings, conscientiousness, and neuroticism. Third, the successful downregulation of emotion is modulated by openness to experience and habitual use of reappraisal. Fourth, the ability to regulate emotions is best predicted by a combination of brain activity and personality as well temperamental traits. Using a multimethodological analysis approach, we provide a first step toward a causal model of individual differences in emotion regulation ability by linking biological systems underlying emotion regulation with descriptive constructs.

When assessing the psychological suitability for the profession of a pilot, it is important to consider personality traits and psychomotor abilities. Our study aimed at estimating the role of temperamental traits as components of pilots' personality in eye-hand co-ordination. The assumption was that differences in the escalation of the level of temperamental traits, as measured with the Formal Characteristic of Behaviour-Temperament Inventory (FCB-TI), will significantly influence eye-hand co-ordination. At the level of general scores, enhanced briskness proved to be the most important trait for eye-hand co-ordination. An analysis of partial scores additionally underlined the importance of sensory sensitivity, endurance and activity. The application of eye-hand co-ordination tasks, which involve energetic and temporal dimensions of performance, helped to disclose the role of biologically-based personality traits in psychomotor performance. The implication of these findings for selecting pilots is discussed.

Prenatal psychosocial exposures can significantly affect infant health and development. Infants with higher temperamental negativity are theorized to be more susceptible to environmental exposures. We evaluated the interaction of prenatal maternal exposures and infant temperamental negativity to predict infant cortisol response to mildly challenging mother-infant interaction tasks. Participants included 322 Mexican American mother-infant dyads (mother age 18–42; 82% Spanish-speaking; modal family income $10,000–$15,000). Mothers reported depressive symptoms and social support prenatally and infant temperamental negativity at 6 weeks postpartum. Salivary cortisol was collected from infants before and after mother-infant interaction tasks at 12 weeks. Higher prenatal maternal depressive symptoms and lower social support predicted higher cortisol among infants with higher temperamental negativity. Higher infant temperamental negativity predicted an increase in maternal distress and a decrease in social support from prenatal to 12 weeks postpartum. Interactive influences of maternal social-contextual factors and infant temperament may influence the development of infant neurobiological regulation and promote or strain maternal and infant adaptation over time.

We investigated the degree to which toddlers’ observed emotional states, toddlers’ temperamental traits, and their interaction accounted for variance in mothers’ and fathers’ parenting. Main effects of two emotional states (positive emotion and negative emotion), three temperamental traits (negative affectivity, effortful control, and surgency) as well as state-by-trait interactions, were examined in relation to parental sensitivity, positive affect, and negative affect. The hypothesis that toddlers’ temperamental traits would moderate the association between their observed emotional states and parenting was partially supported. Significant state-by-trait interactions were found in models predicting the probability that mothers and fathers expressed negative affect towards their toddlers. For parental sensitivity and positive affect, only main effects of temperament and/or emotion expression accounted for variance in parenting. PMID:28479643

Executive Function and Temperamental Fear Concurrently Predict Deception in School-Aged Children.

The decision to intentionally withhold truthful information, or deception, is a key component of moral development and may be a precursor to more serious anti-social tendencies. Two factors, executive function and temperamental fear are each thought to influence childhood deception. Few studies, however, have explored deception in relation to both of these factors simultaneously. This was the goal of the present study. Executive function, as measured by a working memory task, and temperamental fear, as measured via maternal report were assessed in relation to observed deceptive behavior among 6 - 9-year-old children ( N = 43). Results showed that children displaying high working memory capacity and high temperamental fear were more likely to exhibit deceptive behavior. Implications for predictors of childhood deception and applications for moral education are discussed.

Difficult conditions during childhood can limit an individual's development in many ways. Factors such as being raised in an at-risk family, child temperamental traits or maternal traits can potentially influence a child's later behaviour. The present study investigated the extent of regulatory problems in 6-month-old infants and their link to temperamental traits and impact on externalizing and internalizing problems at 36 months. Moderating effects of maternal distress and maternal depressive symptoms were tested as well. In a quasi-experimental, longitudinal study, a sample of 185 mother-infant dyads at psychosocial risk was investigated at 6 months with SFS (infants' regulatory problems) and at 3 years with CBCL (children's behavioural problems), EAS (children's temperament), ADS (maternal depressive symptoms) and PSI-SF (maternal stress). A hierarchical regression analysis yielded a significant association between infants' regulatory problems and both externalizing and internalizing behaviour problems at age 3 (accounting for 16% and 14% variance), with both externalizing and internalizing problems being linked to current maternal depressive symptoms (12 and 9% of the variance). Externalizing and internalizing problems were found to be related also to children's temperamental difficulty (18 and 13% of variance) and their negative emotionality. With temperamental traits having been taken into account, only feeding problems at 6 months contributed near-significant to internalizing problems at 3 years. Our results underscore the crucial role of temperament in the path between early regulatory problems and subsequent behavioural difficulties. Children's unfavourable temperamental predispositions such as negative emotionality and generally "difficult temperament" contributed substantially to both externalizing and internalizing behavioural problems in the high-risk sample. The decreased predictive power of regulatory problems following the inclusion of temperamental variables indicates a mediation effect of temperamental traits in the path between early regulatory problems and subsequent behavioural problems. Our results support the main effects of a child's temperament, and to some degree maternal depressive symptoms, rather than the diathesis stress model of interaction between risky environment and temperamental traits.

Links Between Mothers’ Coping Styles, Toddler Reactivity, and Sensitivity to Toddler’s Negative Emotions

2011-01-01

The extent to which engaged maternal coping styles moderate the association between toddler’s temperamental reactivity and mothers’ sensitivity to children’s negative emotions was examined in 89 mother-child dyads. Primiparous mothers completed a measure of coping styles prenatally. When toddlers were 16 months old, mothers completed a measure of perceived toddler temperament and a self-report of how they respond to toddler negative emotions, and maternal sensitivity and temperamental reactivity were observed during emotionally arousing tasks in the laboratory. Mothers’ disengaged coping style was positively associated with self-reported insensitive responses to children’s negative emotions. Engaged coping moderated the association between toddler temperamental reactivity and both self-reported insensitive responses and observed maternal sensitivity, such that temperamental reactivity was more strongly linked with less sensitive maternal behavior when engaged coping was low.

Despite theoretical discrepancies between different concepts of temperament, some core dimensions are thought to be common to the various models. We compared temperamental traits derived from the New York Longitudinal Study (NYLS) model and the Cloninger dimensions in the developmental course and investigated the associations of temperament with sex as well as with obstetric risks or psychosocial risks present at birth. Participants were 151 boys and 157 girls born at differing degrees of obstetric and psychosocial risk from a longitudinal study on a high-risk community sample. In infancy and childhood, NYLS-derived temperamental characteristics were assessed by a highly structured parent interview and standardized behavioral observations. At age 15 years, the Junior Temperament and Character Inventory/12-18 was administered. Moderate correlations were found between Junior Temperament and Character Inventory scales in adolescence and NYLS-derived factors in childhood. The psychosocial risk load seemed to influence the expression of novelty seeking or corresponding NYLS-derived factors, whereas the obstetric risks did not contribute to variation in temperament. Our findings further support highly sex-specific gene x environment interactions on temperament in the developmental course. The content of our NYLS-derived factors and the specific type of association across different temperament constructs fit into the increasing consensus regarding a small number of higher-order temperamental traits.

Physical inactivity is a leading cause of mortality worldwide. Many patterns of physical activity involvement are established early in life. To date, the role of easily identifiable early-life individual predictors of PA, such as childhood temperament, remains relatively unexplored. Here, we tested whether childhood temperamental activity level, high intensity pleasure, low intensity pleasure, and surgency predicted engagement in physical activity (PA) patterns 11 years later in adolescence. Data came from a longitudinal community study (N = 206 participants, 53% females, 70% Caucasian). Parents reported their children's temperamental characteristics using the Child Behavior Questionnaire (CBQ) when children were 4 & 5 years old. Approximately 11 years later, adolescents completed self-reports of PA using the Godin Leisure Time Exercise Questionnaire and the Youth Risk Behavior Survey. Ordered logistic regression, ordinary least squares linear regression, and Zero-inflated Poisson regression models were used to predict adolescent PA from childhood temperament. Race, socioeconomic status, and adolescent body mass index were used as covariates. Males with greater childhood temperamental activity level engaged in greater adolescent PA volume (B = .42, SE = .13) and a 1 SD difference in childhood temperamental activity level predicted 29.7% more strenuous adolescent PA per week. Males' high intensity pleasure predicted higher adolescent PA volume (B = .28, SE = .12). Males' surgency positively predicted more frequent PA activity (B = .47, SE = .23, OR = 1.61, 95% CI: 1.02, 2.54) and PA volume (B = .31, SE = .12). No predictions from females' childhood temperament to later PA engagement were identified. Childhood temperament may influence the formation of later PA habits, particularly in males. Boys with high temperamental activity level, high intensity pleasure, and surgency may directly seek out pastimes that involve PA. Indirectly, temperament may also influence caregivers' perceptions of optimal activity choices for children. Understanding how temperament influences the development of PA patterns has the potential to inform efforts aimed at promoting long-term PA engagement and physical health.

Deficits in mindfulness-related capacities have been described in borderline personality disorder (BPD). However, little research has been conducted to explore which factors could explain these deficits. This study assesses the relationship between temperamental traits and childhood maltreatment with mindfulness in BPD. A total of 100 individuals diagnosed with BPD participated in the study. Childhood maltreatment was assessed using the Childhood Trauma Questionnaire (CTQ-SF), temperamental traits were assessed using the Zuckerman-Khulman Personality Questionnaire (ZKPQ), and mindfulness capabilities were evaluated with the Five Facet Mindfulness Questionnaire (FFMQ). Hierarchical regression analyses were performed including only those CTQ-SF and ZKPQ subscales that showed simultaneous significant correlations with mindfulness facets. Results indicated that neuroticism and sexual abuse were predictors of acting with awareness; and neuroticism, impulsiveness and sexual abuse were significant predictors of non-judging. Temperamental traits did not have a moderator effect on the relationship between childhood sexual abuse and mindfulness facets. These results provide preliminary evidence for the effects of temperamental traits and childhood trauma on mindfulness capabilities in BPD individuals. Further studies are needed to better clarify the impact of childhood traumatic experiences on mindfulness capabilities and to determine the causal relations between these variables.

Consistently with the involvement of affective temperaments in professional choices, our research team is aiming to outline the temperamental profile of subjects who are applying to enter a military career in the Italian Armed Forces. In this study we aim to verify the importance of temperamental traits not only in choosing the military career as a profession, but also in passing or failing the entrance examinations. We compared the affective temperaments (evaluated by TEMPS-A[P]) of those applying to become a cadet officer in the Italian Navy, divided into various subgroups depending on whether they passed or failed the entrance examination at various levels (high school final test, medical (physical and psychiatric), mathematical examination and aptitude test). We also tested for correlations between grades received and temperamental scores. Higher scores for those with a hyperthymic and lower scores for those with a depressive, cyclothymic or irritable temperament characterized applicants taking medical exams and aptitude tests. Higher scores on the high school final test correlated with lower hyperthymic, cyclothymic and irritable temperament scores. No correlations were found between temperamental traits and mathematical examinations. Multivariate analysis stressed the negative impact of a cyclothymic temperament and the poor discriminant power of temperaments regarding medical and mathematical examinations, and aptitude tests. Conversely, temperaments showed good discriminant power as far as psychiatric examinations are concerned. Hyperthymic temperamental traits appear to be important not only in choosing a profession, but also in passing entrance examinations. Even so, affective temperaments (strong hyperthymic and weak cyclothymic, depressive and irritable traits) are the only successfully predictors of the outcome of psychiatric examinations and, to a lesser extent, medical examinations and aptitude tests. Achieving high school graduation and passing mathematical exams are independent of temperamental traits. Copyright © 2013 Elsevier B.V. All rights reserved.

To investigate differences in psychopathological, temperamental and characteristic factors between young adults with and without persistent Attention-Deficit Hyperactivity disorder (ADHD) symptoms. A total of 429 university students were divided into three groups: persistent adult ADHD (n = 53), only childhood ADHD (n = 56) and healthy controls (n = 320). The Korean Adult ADHD Scale, Korean Wender-Utah Rating Scale, Beck Depression Inventory-II, Beck Anxiety Inventory, Barratt Impulsiveness Scale, Korean Young Internet Addiction Scale, and Temperament Character Inventory-Revised (TCI-R; based on Cloninger's seven factor model of temperament and character) were used to evaluate psychopathological factors. Participants with persistent adult ADHD symptoms had significantly higher levels of childhood ADHD, depression, anxiety and the Internet addiction symptoms than did the only-childhood ADHD and control groups. The adult ADHD group also had significantly higher tendencies toward novelty seeking, harm avoidance, and self-transcendence, as well as low self-directedness and cooperativeness. Results suggest that persistent ADHD is associated with several unfavourable psychopathological, temperamental and characteristic factors. Therefore, thorough evaluation of these factors for childhood ADHD could help predict prognoses and provide treatment plans for preventing persistent ADHD into adulthood.

Relations between temperamental fear and risky pedestrian behavior.

Child pedestrian injury poses a significant global public health challenge. This study examines relations between temperamental fear and children's risky pedestrian behavior, utilizing mediation analytic strategies to study underlying mechanisms of the hypothesized relation. As part of a larger study, 240 seven- and eight-year-old children completed 30 crossings in a virtual reality (VR) pedestrian environment. Three pedestrian behaviors were considered: start gap (lag after a traffic gap appears before child initiates crossing into the gap), time to contact (TTC; gap between avatar and the lead oncoming vehicle), and hits (collisions with vehicles in simulated crossings). Temperamental fear was measured by parent report. Fearful children were more likely to be struck by virtual vehicles, and the relation between fear and risky pedestrian behaviors was mediated by start gap and TTC. Specifically, children who were temperamentally more fearful were more likely to hesitate before initiating crossing, which led to shorter gaps between themselves and the oncoming vehicle, hence causing them to be more likely to be hit by virtual vehicles. Gender interacted with fear, such that fearful girls were most likely to be hit. Both temperamental fear and gender influenced the risk of child pedestrian injuries. Delayed entry into traffic and shorter gaps between children and oncoming vehicles may underlie this relation. Future research should explore how these factors might influence the effectiveness of prevention programs. Copyright © 2015. Published by Elsevier Ltd.

Impact of temperamental mood lability on depressive mixed state.

PubMed

Benazzi, Franco

2006-01-01

Cyclothymic temperament (which includes mood lability) is common in bipolar II disorder (BP-II). Depressive mixed state (DMX), a major depressive episode (MDE) mixed with intra-episode hypomanic symptoms (3 or more, according to a recently validated definition), was found to be common in BP-II and not uncommon in major depressive disorder (MDD). The study aim was to find the impact of temperamental mood lability (TML) on DMX. Consecutive 148 BP-II and 117 MDD outpatients presenting for MDE treatment were interviewed by the Structured Clinical Interview for DSM-IV as modified by Benazzi and Akiskal to reduce the false negative BP-II. Intra-MDE hypomanic symptoms were systematically assessed. Kraepelin, Angst, and Akiskal's definitions of temperamental mood lability (i.e., frequent up and down fluctuations of mood between major mood episodes since young age) were followed. DMX was present in 61.5%, TML in 52.8%. In the DMX sample, TML was present in 57.6%, and in the non-DMX sample TML was present in 45.0% (OR = 1.6, 95% CI = 1.0-2.7). In the DMX sample, independent predictors of DMX with TML were BP-II and young age at onset. Intra-MDE hypomanic symptoms, and MDE, melancholic and atypical symptoms were not significantly different between DMX patients with TML and DMX patients without TML, apart from more temperamental interpersonal sensitivity in DMX patients with TML (OR = 2.0, 95% CI = 1.0-3.8). DMX patients with TML had a younger onset age, suggesting that TML may facilitate the onset of DMX or that it may be a precursor of DMX. The association of BP-II with DMX, TML, and interpersonal sensitivity can make the course of BP-II more unstable and its treatment more complex.

Temperamental factors in remitted depression: The role of effortful control and attentional mechanisms.

PubMed

Marchetti, Igor; Shumake, Jason; Grahek, Ivan; Koster, Ernst H W

2018-08-01

Temperamental effortful control and attentional networks are increasingly viewed as important underlying processes in depression and anxiety. However, it is still unknown whether these factors facilitate depressive and anxiety symptoms in the general population and, more specifically, in remitted depressed individuals. We investigated to what extent effortful control and attentional networks (i.e., Attention Network Task) explain concurrent depressive and anxious symptoms in healthy individuals (n = 270) and remitted depressed individuals (n = 90). Both samples were highly representative of the US population. Increased effortful control predicted a substantial decrease in symptoms of both depression and anxiety in the whole sample, whereas decreased efficiency of executive attention predicted a modest increase in depressive symptoms. Remitted depressed individuals did not show less effortful control nor less efficient attentional networks than healthy individuals. Moreover, clinical status did not moderate the relationship between temperamental factors and either depressive or anxiety symptoms. Limitations include the cross-sectional nature of the study. Our study shows that temperamental effortful control represents an important transdiagnostic process for depressive and anxiety symptoms in adults. Copyright © 2018 Elsevier B.V.

Shy children are less sensitive to some cues to facial recognition.

PubMed

Brunet, Paul M; Mondloch, Catherine J; Schmidt, Louis A

2010-02-01

Temperamental shyness in children is characterized by avoidance of faces and eye contact, beginning in infancy. We conducted two studies to determine whether temperamental shyness was associated with deficits in sensitivity to some cues to facial identity. In Study 1, 40 typically developing 10-year-old children made same/different judgments about pairs of faces that differed in the appearance of individual features, the shape of the external contour, or the spacing among features; their parent completed the Colorado childhood temperament inventory (CCTI). Children who scored higher on CCTI shyness made more errors than their non-shy counterparts only when discriminating faces based on the spacing of features. Differences in accuracy were not related to other scales of the CCTI. In Study 2, we showed that these differences were face-specific and cannot be attributed to differences in task difficulty. Findings suggest that shy children are less sensitive to some cues to facial recognition possibly underlying their inability to distinguish certain facial emotions in others, leading to a cascade of secondary negative effects in social behaviour.

Current treatment of children with dental behaviour management problems (DBMP) is based on the presupposition that their difficulties are caused by dental fear, but is this always the case? The aim of this study was to study temperamental reactivity, negative emotionality, and other personal characteristics in relation to DBMP in 8- to 12-year-old children. Forty-six children referred because of DBMP (study group) and 110 children in ordinary dental care (reference group) participated. The EASI tempramental survey assessed temperamental reactivity and negative emotionality, the Child Behaviour Questionnaire internalizing and externalizing behaviour problems, and the Children's Fear Survey Schedule general and dental fears. Cluster analyses and tree-based modelling were used for data analysis. Among the five clusters identified, one could be characterized as 'balanced temperament'. Thirty-five per cent of the reference group compared to only 7% of the study group belonged to this cluster. Negative emotionality was the most important sorting variable. Children referred because of DBMP differed from children in ordinary dental care, not only in dental fear level, but also in personal characteristics. Few of the referred children were characterized by a balanced temperament profile. It is important to consider the dual impact of emotion dysregulation and emotional reactivity in the development of DBMP.

Willoughby, Michael T.; Stifter, Cynthia A.; Gottfredson, Nisha C.

2015-01-01

This study investigated the factor structure of observational indicators of children’s temperament that were collected across the first three years of life in the Family Life Project (N = 1205) sample. A four-factor model (activity level, fear, anger, regulation), which corresponded broadly to Rothbart’s distinction between reactivity and regulation, provided an acceptable fit the observed data. Tests of measurement invariance demonstrated that a majority of the observational indicators exhibited comparable measurement properties for male vs. female, black vs. white, and poor vs. not-poor children, which improved the generalizability of these results. Unadjusted demographic group comparisons revealed small to moderate sized differences (Cohen ds = |.23 – .42|) in temperamental reactivity and moderate to large sized differences (Cohen ds = −.64 – −.97) in regulation. Collectively, demographic variables explained more of the variation in regulation (R2 = .25) than in reactivity (R2 = .02 – .06). Follow-up analyses demonstrated that race differences were substantially diminished in magnitude and better accounted for by poverty. These results help to validate the distinction between temperamental reactivity and regulation using observational indicators. PMID:25733489

Which temperamental characteristics are associated with substance use in subjects with psychotic and mood disorders?

PubMed

Liraud, F; Verdoux, H

2000-02-14

The aim of this study was to assess the associations between substance use disorders and temperamental characteristics in subjects with non-affective psychotic disorders or mood disorders. Consecutively hospitalized patients were interviewed with a structured diagnostic interview to define DSM-IV diagnoses, including those of substance use. Temperamental characteristics were measured using the Sensation-Seeking Scale (SSS), the Barratt Impulsivity Scale (BIS) and the Physical Anhedonia Scale. Inpatients (n=103) with non-affective psychotic disorders (n=45) or mood disorders (n=58) were included. Among these patients, 25.2% presented with a lifetime (LT) history of alcohol abuse/dependence and 23.3% presented with a LT history of cannabis abuse/dependence. A LT history of alcohol misuse was independently associated with higher scores at the 'experience seeking' and 'disinhibition' subscales of the SSS. A LT history of cannabis misuse was independently associated with higher scores on the 'disinhibition' subscale of the SSS and on the 'non-planning activity' subscale of the BIS. These results suggest that sensation-seeking and impulsivity are temperamental characteristics that may favor substance use in patients with psychotic or mood disorders, independently from categorical diagnoses.

Sensitivity to social and non-social threats in temperamentally shy children at-risk for anxiety.

PubMed

LoBue, Vanessa; Pérez-Edgar, Koraly

2014-03-01

In the current brief report, we examined threat perception in a group of young children who may be at-risk for anxiety due to extreme temperamental shyness. Results demonstrate specific differences in the processing of social threats: 4- to 7-year-olds in the high-shy group demonstrated a greater bias for social threats (angry faces) than did a comparison group of low-shy children. This pattern did not hold for non-social threats like snakes: Both groups showed an equal bias for the detection of snakes over frogs. The results suggest that children who are tempermentally shy have a heightened sensitivity to social signs of threat early in development. These findings have implications for understanding mechanisms of early threat sensitivity that may predict later socioemotional maladjustment. © 2013 John Wiley & Sons Ltd.

Youth Withdrawal Moderates the Relationhips between Neighborhood Factors and Internalizing Symptoms in Adolescence

2015-01-01

Adolescents higher in temperamental withdrawal are at risk for anxiety and depressive symptoms; however, not all youth higher in withdrawal exhibit internalizing symptoms, suggesting that contextual factors may influence these relationships. We examined whether youth withdrawal moderates the relationships between neighborhood processes (crime, social cohesion) and internalizing symptoms and whether findings were consistent with diathesis-stress or differential susceptibility hypotheses. Participants were 775 adolescents (M=15.50 ± 0.56 years, 72% male, 76% White). Adolescents higher in withdrawal manifested higher internalizing symptoms in the context of lower neighborhood crime and lower neighborhood social cohesion than youth lower in withdrawal, supporting diathesis-stress. These findings elucidate neighborhood processes associated with internalizing symptoms, which can inform models of risk and resilience for these symptoms among children who differ in temperamental withdrawal.

Solmeyer, Anna; Feinberg, Mark E

2011-01-01

We explored how parent gender, infant temperament, and coparenting dynamics worked together to shape mothers’ and fathers’ depressive symptoms, stress, and parental efficacy during early parenthood. We were interested in the coparenting relationship as a context that shapes how parents respond to their infant’s temperamental qualities. Participants were 139 couples who had recently given birth to their first child. Parent reports of temperament were collected when the infant was 4–8 months old and reports of coparenting and parent adjustment were collected at 13 months. Two-level random intercept models revealed interactions among temperament and coparenting, highlighting the family system as a context for how men and women adapt to their parenting role. There was little evidence for mother-father differences in these associations. PMID:21868100

2010-01-01

Successful development during the first year of life is dependent on the infant’s ability to regulate behavioral and physiological state in response to unpredictable environmental challenges. While most infants develop skills to self-soothe and regulate behavior, a subset lacks these skills and develops regulatory disorders (RD). Objectives To evaluate the component features of RD by determining if infants with RD differ from typically developing infants on measures of temperament, respiratory sinus arrhythmia, heart rate, and mother-infant interactions. Methods Parents of 50 9-month old infants completed behavioral questionnaires that provided information necessary to complete the Regulatory Disorders Checklist, which evaluates for difficulties in self-regulation and hypersensitivities. Infants with difficulties in both domains were assigned to the RD group. Mothers and their infants were videotaped interacting for 10 minutes. Infant heart rate was monitored before and during the mental development test. Results The RD group (n=10) was more temperamentally difficult and exhibited atypical physiological regulation relative to infants with difficulties in either self-regulation or hypersensitivity (n=25) or infants with no difficulties (n=15). During the mother-infant interactions, the RD group exhibited more high-level withdrawal behaviors, including verbal and physical protests, although there were no differences in the quantity and quality of the maternal approaches. Conclusion Infants with RD have both temperamental and physiological regulation difficulties, and may be in a physiologically state that makes it difficult to moderate behavior in response to social demands. Mothers of RD infants might be taught to modify their behavior to help their infants regulate behavioral and physiological state. PMID:21057324

Cognitive development might be influenced by parenting practices and child temperament. We examined whether the associations between parental warmth, control and intelligence quotient (IQ) may be heightened among children in difficult temperament. Participants were from the Avon Longitudinal Study of Parents and Children (n = 7,044). Temperament at 6 months was measured using the Revised Infant Temperament Questionnaire and classified into ‘easy’ and ‘difficult’. Parental warmth and control was measured at 24 to 47 months and both were classified into 2 groups using latent class analyses. IQ was measured at 8 years using the Wechsler Intelligence Scale for Children and dichotomized (<85 and ≥85) for analyzing effect-measure modification by temperament. Linear regression adjusted for multiple confounders and temperament showed lower parental warmth was weakly associated with lower IQ score [β = -0.52 (95% CI 1.26, 0.21)], and higher parental control was associated with lower IQ score [β = -2.21 (-2.95, -1.48)]. Stratification by temperament showed no increased risk of having low IQ in temperamentally difficult children [risk ratio (RR) = 0.97 95% CI 0.65, 1.45)] but an increased risk among temperamentally easy children (RR = 1.12 95% CI 0.95, 1.32) when parental warmth was low. There was also no increased risk of having low IQ in temperamentally difficult children (RR = 1.02 95% CI 0.69, 1.53) but there was an increased risk among temperamentally easy children (RR = 1.30 95% CI 1.11, 1.53) when parental control was high. For both parental warmth and control, there was some evidence of negative effect-measure modification by temperament on the risk-difference scale and the risk-ratio scale. It may be more appropriate to provide parenting interventions as a universal program rather than targeting children with difficult temperament. PMID:27027637

Comparative analysis of affective temperament in patients with difficult-to-treat and easy-to-treat major depression and bipolar disorder: Possible application in clinical settings.

PubMed

Takeshima, Minoru; Oka, Takashi

2016-04-01

Difficult-to-treat major depressive disorder (MDD-DT), which involves antidepressant refractoriness or antidepressant-related adverse psychiatric effects, is bipolar in nature; therefore, it may share common temperamental features with bipolar disorder. To examine this hypothesis, affective temperament was compared between MDD-DT, easy-to-treat major depressive disorder (MDD-ET), and bipolar disorder. Affective temperament was measured in 320 patients (69, 56, and 195 with MDD-ET, MDD-DT, and bipolar disorder, respectively) using the self-rated questionnaire version of the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego (TEMPS-A), with between-group differences examined using multiple logistic regression analysis controlling for confounders. Optimal cut-off points for TEMPS-A scores to discriminate between diagnostic groups were determined using receiver-operating characteristic analysis. Of the five temperamental domains, the mode for cyclothymic temperament score was highest, followed by those of bipolar disorder, MDD-DT, and MDD-ET. The cyclothymic temperament score discriminated significantly between bipolar disorder and MDD-DT (odds ratio [OR]: 1.12, 95% confidence interval [CI]: 1.04-1.20, p=0.0022), MDD-DT and MDD-ET (OR: 1.15, 95% CI: 1.01-1.31, p=0.0334), and bipolar and major depressive disorders (OR: 1.17, 95% CI: 1.07-1.28, p=0.0003). Optimal cut-off points for the cyclothymic temperament scores to discriminate between bipolar disorder and major depressive disorder and MDD-DT and MDD-ET were 9 (sensitivity: 64.6%, specificity: 76.0%) and 6 (66.1%, 62.3%), respectively. MDD-DT has a quantitatively stronger bipolar temperamental feature, cyclothymic temperament, relative to that of MDD-ET. Cut-off points determined in this study could be clinically helpful. Because of our study design, longitudinal changes in temperamental scores during treatment cannot be fully excluded. Copyright © 2016 Elsevier Inc. All rights reserved.

Preterm Infants Who Are Prone to Distress: Differential Effects of Parenting on 36-month Behavioral and Cognitive Outcomes

Poehlmann, Julie; Hane, Amanda; Burnson, Cynthia; Maleck, Sarah; Hamburger, Elizabeth; Shah, Prachi E.

2012-01-01

Background The differential susceptibility (DS) model suggests that temperamentally prone-to-distress infants may exhibit adverse outcomes in negative environments but optimal outcomes in positive environments. This study explored temperament, parenting, and 36-month cognition and behavior in preterm infants using the DS model. We hypothesized that temperamentally prone to distress preterm infants would exhibit more optimal cognition and fewer behavior problems when early parenting was positive; and less optimal cognition and more behavior problems when early parenting was less positive. Methods Participants included 109 preterm infants (gestation < 37 weeks) and their mothers. We assessed neonatal risk and basal vagal tone in the neonatal intensive care unit (NICU); infant temperament and parenting interactions at 9 months postterm; and child behavior and cognitive skills at 36 months postterm. Hierarchical regression analyses tested study hypotheses. Results Temperamentally prone-to-distress infants exhibited more externalizing problems if they experienced more critical parenting at 9 months (β= -.20, p<0.05) but fewer externalizing problems with more positive parenting. Similarly, variations in maternal positive affect (β= .25, p< .01) and intrusive behaviors (β= .23, p< .05) at 9 months predicted 36-month cognition at high but not at low levels of infant temperamental distress. Higher basal vagal tone predicted fewer externalizing problems (β= -.19, p< .05). Conclusions Early parenting behaviors relate to later behavior and development in preterm infants who are temperamentally prone to distress, and neonatal basal vagal tone predicts subsequent externalizing behaviors. These findings suggest that both biological reactivity and quality of caregiving are important predictors for later outcomes in preterm infants and may be considered as foci for developmental surveillance and interventions.

Sex differences in psychological adjustment from infancy to 8 years.

PubMed

Prior, M; Smart, D; Sanson, A; Oberklaid, F

1993-03-01

The objective of this study was to explore sex differences in development from infancy to 8 years of age in a community sample. Measures of biological, social, interactive, and parental functioning as well as teacher reports were obtained. There were minimal differences in infancy, but major psychosocial differences emerged with increasing age. In the biological sphere boys were disadvantaged only in ratings of language and motor skills at 3 to 4 years old. They showed greater temperamental "difficulty" and low persistence factor scores from 5 years onward. Boys were significantly more likely to have problems with adaptive behavior and social competence and to show behavior problems of the hyperactive and aggressive type, as rated by mothers. Parent and family functioning measures did not differentiate between the sexes. Teachers rated boys as having more problems in academic and behavioral domains the first 3 years of school. Path analyses combining data sets gathered when the children were 3 to 8 years old demonstrated the differential courses of development for boys and girls although temperamental flexibility was the best predictor of behavioral adjustment for both sexes. A social learning explanation of the increased incidence of problems among males is supported, although biological influences are not ruled out.

Temperament and Externalizing Behavior: Social Preference and Perceived Acceptance as Protective Factors

2009-01-01

The purpose of this study was to explore the role of social preference and perceived acceptance as moderators of the relation between child temperament and externalizing behavior. Participants included 399 children evaluated at pre-kindergarten and kindergarten assessments. Pre-kindergarten children characterized by high temperamental Surgency/Extraversion were more likely to exhibit hyperactivity and aggression in the kindergarten classroom. In addition, kindergarten perceived acceptance and social preference moderated the relation between pre-kindergarten Surgency/Extraversion and kindergarten hyperactivity for girls only. Girls who were characterized by high temperamental Surgency/Extraversion, high perceived acceptance, and low social preference were at risk for higher levels of teacher-reported and peer-nominated hyperactivity. In contrast, accurately high perceived acceptance was a protective factor for high temperamental Surgency/Extraversion. Findings are discussed in terms of risk and protective factors for externalizing behavior. PMID:18605827

Self-injurious behavior (SIB) is increasingly popular in psychically ill adolescents, especially in girls with posttraumatic stress (PTSD) and personality disorders. Adolescents with SIB frequently exhibit neurofunctional and psychopathological deficits. We speculated that specific neuropsychological deficits and temperamental factors could predispose patients to SIB and prospectively explored adolescent psychiatric patients with and without SIB in order to find out differences in psychopathology, and neuropsychological or temperamental factors. Ninety-nine psychically ill adolescent girls with SIB, aged 12-19 years and treated at our clinic, were prospectively recruited during a period of 5.5 years (1999-2005). The clinical (ICD-10) diagnoses were mainly substance abuse, eating disorders, depression, PTSD and personality disorders. The control group was also prospectively recruited during the same period and consisted of 77 girls with similar diagnoses and ages but no SIB. All patients were subjected to the same selection of clinical and neuropsychological tests, mainly self-rating questionnaires and tests evaluating executive functions. Adolescent girls with psychiatric disease and SIB were more severely traumatized and depressed. They reported severe emotional and behavioral problems and deficits of self-regulation. In addition, their parents more frequently had psychiatric problems. Temperament, intelligence, investigated executive functions and presence of dissociative symptoms were not different in patients with and without SIB. We could not verify our primary hypothesis that SIB is related to specific neuropsychological deficits or temperamental factors. SIB was associated with traumatic experience, depression, problems of self-regulation and parental psychiatric disease. The prevention of SIB should therefore focus on improving affect regulation, the management of emotional distress and problem-solving strategies. (c) 2008 S. Karger AG, Basel

Several authors emphasize the close relationship between self-esteem and athletic performance; such a relationship may raise the following question: by saying "strong" or "without any physical condition", is it a fair presentation of the individual's abilities or he reveals the most fundamental aspects of his personality, such as emotional temperament? To evaluate self-esteem, physical self and temperamental profile in a group of sportsmen, and to look for a relationship between these variables and athletic performance. We performed a cross-sectional, descriptive and analytic study in 80 young handball players of the "senior" category. We assessed self-esteem using the Rosenberg Self Esteem Scale, physical self-using the Physical Self-Inventory (PSI), and temperamental profile using the Temperament Evaluation of Memphis, Paris and San Diego Auto-questionnaire (TEMPS-A). Athletic performance was evaluated by the team coach by means of a score ranging from 1 to 10. High self-esteem was correlated to female gender (p=0.03), to an early start of physical activity (p<0.01), and certain dimensions of the physical self: perceived physical value (p=0.02), appearance (p<0.01), and the global score (p=0.01). Athletic performance was correlated to high self-esteem (p<0.01) and to two dimensions of the physical self: the global score (p=0.01) and the perceived physical value (p<0.01). Hyperthymic temperament was associated with high self-esteem (p=0.001). Good athletic performance was associated with hyperthymic (p<0.01) and cyclothymic (p<0.01) temperament. Low athletic performance was associated with depressive (p=0.04) and irritable (p=0.01) temperament. Our study shows the close relationship between selfesteem, temperamental profile and athletic performance. We suggest that the intervention of a psychiatrist or a psychologist aimed at improving sportsmen's' self-esteem might help to achieve better athletic performance. In this intervention, the individual temperamental profile should be taken into account.

Viana, Andres G; Gratz, Kim L; Bierman, Karen L

2013-01-01

Temperamental vulnerabilities (e.g., behavioral inhibition, anxiety sensitivity) and cognitive biases (e.g., interpretive and judgment biases) may exacerbate feelings of stress and anxiety, particularly among late adolescents during the early years of college. The goal of the present study was to apply person-centered analyses to explore possible heterogeneity in the patterns of these four risk factors in late adolescence, and to examine associations with several anxiety outcomes (i.e., worry, anxiety symptoms, and trait anxiety). Cluster analyses in a college sample of 855 late adolescents revealed a Low-Risk group, along with four reliable clusters with distinct profiles of risk factors and anxiety outcomes (Inhibited, Sensitive, Cognitively-Biased, and Multi-Risk). Of the risk profiles, Multi-Risk youth experienced the highest levels of anxiety outcomes, whereas Inhibited youth experienced the lowest levels of anxiety outcomes. Sensitive and Cognitively-Biased youth experienced comparable levels of anxiety-related outcomes, despite different constellations of risk factors. Implications for interventions and future research are discussed.

In the last decade, the comprehension of affective temperaments has helped us to outline the boundaries of mood disorders, and to expand our knowledge of nosographic areas other than those of affectivity, even if affectivity is closely related to them. In the field of substance use disorders, the temperamental profile of heroin addicts and alcoholics has been discussed elsewhere, but no comparison has yet been made between these two patient populations. Such a comparison would help to shed light on the pathogenetic mechanisms that link temperament with substance abuse. 63 Heroin Use Disorder (HUD) and 94 Alcohol Use Disorder (AUD) patients were compared with 130 healthy controls, with the aim of outlining affective temperament quantity and typology according to the formulation of Akiskal and Mallya. Cyclothymic temperamental quantity differentiated - both at the univariate and multivariate levels - between patients who had various different types of Substance Use Disorder, largely irrespective of the principal substance of abuse (heroin or alcohol); irritable temperament quantity differentiated HUD patients from AUD patients. Hyperthymic temperament typology seemed to be more frequent in healthy controls at both univariate and multivariate levels. Cross-sectional study. Our analyses suggest that cyclothymic temperament quantity could best correspond to the temperamental profile of Substance Use Disorder patients independently of principal substance of abuse (alcohol or heroin), and that irritable temperament quantity may differentiate HUD from AUD patients. Hyperthymic temperament typology seemed to be highly protective for HUD and, though a bit less, for AUD patients, and was a typical feature of healthy controls. Copyright © 2017 Elsevier B.V.

The aim of the study was to identify individual risk factors for traumatic dental injuries (TDI) among Swedish children aged 0-17 years. The studied risk factors were temperamental reactivity of the child, family structure, parent's country of birth, and the socioeconomic status of the family represented by parental education and occupation. The study included 2363 children in four different age cohorts at 12 public dental service clinics in Sweden, representing different types of demographic areas, both rural and urban. Data were collected from parents and children through an interview and questionnaires. The more social and active children in the two older age cohorts showed less occasions of TDI. Having one parent/guardian protected the child from dental injury just as well as two parents/guardians. Parents born outside of the Nordic countries showed children with less TDI. Low parental education was related to more occasions of TDI among the children. This study has increased the knowledge on certain individual risk factors for TDI. To prevent dental injuries, information could be given to families and children at risk. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Assimilation and Individual Differences in Emotion: The Dynamics of Anger and Approach Motivation.

Lechuga, Julia; Fernandez, Norma P

2011-03-01

Individuals who cross cultural boundaries face many challenges when trying to adapt to a receiving culture. Adaptation challenges such as learning to maneuver across societal domains may become increasingly complex if structural level factors such as discrimination are present. Researchers have conceptualized acculturation as a relatively autonomous decision indicating that four acculturation strategies exist: assimilation, separation, integration, and marginalization. Moreover, researchers have also long debated the link between acculturation strategy, adaptation hassles and negative health outcomes. However, models seeking to explain how individual difference and structural level variables may influence each other and subsequently influence acculturation and adaptation are needed. The purpose of this study is to lay the foundation for the conceptualization of such a model. We propose that temperamental predispositions to negative emotionality, anger, and impulsivity may highlight discrimination which in turn may lead to increases in acculturative stress and negative markers of psychosocial well-being. We used SEM to test our hypothesized model. Results supported a modified model. Implications for the measurement of adaptation and interventions are discussed.

Developmental origins of infant emotion regulation: Mediation by temperamental negativity and moderation by maternal sensitivity.

Emotion regulation is essential to cognitive, social, and emotional development and difficulties with emotion regulation portend future socioemotional, academic, and behavioral difficulties. There is growing awareness that many developmental outcomes previously thought to begin their development in the postnatal period have their origins in the prenatal period. Thus, there is a need to integrate evidence of prenatal influences within established postnatal factors, such as infant temperament and maternal sensitivity. In the current study, prenatal depression, pregnancy anxiety, and diurnal cortisol patterns (i.e., the cortisol awakening response (CAR) and diurnal slope) were assessed in 254 relatively low-risk mother-infant pairs (primarily White, middle-class) in early (M = 15 weeks) and late pregnancy (M = 33 weeks). Mothers reported on infant temperamental negativity (Infant Behavior Questionnaire-Revised) at 3 months. At 6 months, maternal sensitivity (Parent Child Interaction Teaching Scale) and infant emotion regulation behavior (Laboratory Temperament Assessment Battery) were assessed. Greater pregnancy anxiety in early pregnancy and a blunted CAR in late pregnancy predicted higher infant temperamental negativity at 3 months, and those infants with higher temperamental negativity used fewer attentional regulation strategies and more avoidance (i.e., escape behavior) at 6 months. Furthermore, this indirect effect was moderated by maternal sensitivity whereby infants with elevated negativity demonstrated maladaptive emotion regulation at below average levels of maternal sensitivity. These findings suggest that the development of infant emotion regulation is influenced by the ways that prenatal exposures shape infant temperament and is further modified by postnatal caregiving.

Temperament has been defined as the heritable biologically determined core of personality that remains stable throughout the life span and establishes the baseline level of reactivity, mood, and energy of a person. If the link between temperament and mental disorder goes back to the Greco-Roman medicine, Kraepelin was among the first authors to pay attention to the temperamental bases of bipolar disorder. He proposed four temperamental types that he described in the premorbid histories of the majority of manic-depressive patients, and found overrepresented in the biologic relatives of these patients. Building on this ancestry, Akiskal formulated the modern concept of affective temperament, and described five temperaments: depressive, hyperthymic, cyclothymic, irritable, and anxious. According to Akiskal's model, bipolar disorder lies along a continuum from temperament to full-blown episodes of affective illness. A series of recent studies have shown the role played by temperaments in the outbreak of bipolar episodes, their clinical presentation, as well as the illness course and comorbidities. Furthermore modern familial and genetic studies have confirmed the first observations of Kraepelin. It has been recently proposed that affective temperaments may carry distinct evolutionary advantages on the individual or a group level, so that affective disorders would be genetic reservoirs for adaptative temperaments and the price to be paid for the chance of exceptionality. Apart from these theoretical perspectives, paying attention to temperamental components may have important implications for the treatment of bipolar disorder. Finally recent studies confirmed as well, that the concept of affective temperament fulfilled the criteria required to be considered as an endophenotype. Copyright © 2012 L’Encéphale.

Background: Growth and development are the basic science in pediatric medicine. Growth disorder in children is one of the important health problems in the world, especially in developing countries. Regardless of the underlying disease, as the main cause of growth disorders, assessment and correction of nutritional status of these children are very important. Given the fundamental importance of this issue and ascending tendency to use complementary medicine in the world, this article discusses the traditional Iranian philosopher’s views on the role of nutrition in child development. Methods: This study reviews textbooks of traditional medicine, particularly in the field of pediatric medicine with a focus on Canon of Medicine of Avicenna. Results: Temperament is the physiological concept of the human body in traditional medicine and has an important role in health, diagnosis, and treatment of disease. Generally, children are born with warm and wet temperament that provides the best condition for growth. However, the personal temperament of each child determines growth, the need for a variety of food groups, and even physical activity. Different appetite and food preferences in children show temperamental variation. Therefore, children need special management regarding special temperament. In Iranian traditional medicine, special lifestyle orders are discussed in detail according to these differentiations and nutritional management is the most important factor considered. Conclusion: In spite of advances in classical medicine in the prevention and treatment of many diseases, there are still a lot of therapeutic challenges in many health problems. Temperamental approach to the human body in traditional medicine provides a different perspective on the medicine. Reflecting on temperamental view in child development may lead to a better understanding of the diagnosis and treatment of diseases. On the other hand, further research studies based on the reform of nutrition with respect to temperament should be considered as a new strategy in the management of developmental disorders.

This study examined the stability of maternal punitive/high-power discipline (PD) and inductive/authoritative discipline (ID) over the second and third years of life and the effect of maternal discipline on quality of mother-child interactions. Data from a longitudinal sample with 179 mother-toddler dyads were analyzed, and selected factors (i.e., child sex, temperament) that might moderate the association between maternal discipline and quality of mother-child interactions were also examined. Maternal discipline, quality of mother-child interactions, and temperamental moderators were measured at 16-18 months (Time 1) and 34-37 months (Time 2). Results showed that the stability of maternal use of discipline strategies over the toddler years was moderate. Lower maternal use of PD, higher maternal use of ID, and higher preference/reliance on ID (relative to PD) were associated with higher quality of mother-child interactions. Moderation effects of child temperament were also found. High ID and PD were associated with low quality of mother-child relationships in non-temperamentally difficult children but not in temperamentally difficult children.

Over the past fifty years in the Western world the professions and activities that were once practised only by males, are now available to females, too. Affective temperaments, in line with their adaptive function, influence career choices. In general, males and females have proved to have different temperamental profiles. In this study we inquire into the question whether gender differences in temperament have continued unchanged in a field, such as the military career, that has been historically characterized by a male identity. 1426 males and 122 females wishing to become a cadet in the Italian Air Force were tested using TEMPS-A[P] (the Temperament Evaluation of Memphis, Pisa, Paris and San Diego self-questionnaire, Pisan version). Univariate and multivariate analyses failed to distinguish males from females. Both males and females tend to have a high score on the hyperthymic scale (generally, a typical male temperament) and a very low one on the cyclothymic scale (generally, a typical female temperament), with low scores on the depressive and the irritable scales. This study supports the idea that different gender-related temperaments are functional to differences in the roles played by males and females during the biological and social evolutionary process.

We conducted a retrospective study of arsonists referred for psychiatric assessment and found that 88/202 (43.6%) had an IQ of 85 or below. The low IQ group showed more evidence of childhood temperamental disturbance, and a later pattern of internal problems rather than external factors expressing themselves as fire-setting. This study highlights the likelihood of lifelong, temperamental problems being apparent in childhood, and being predictive and possibly causative of fire setting in people with a low IQ. Better understanding of the distinct characteristics of lower IQ arsonists is essential for improved prevention, treatment and management.

Dissociative symptoms are frequent among psychiatric patients and may considerably affect patients' psychopathological condition and treatment outcomes. The objectives of the study are to assess the presence of dissociative symptoms in female patients with mood and anxiety disorders, to investigate their correlation with the clinical severity of the disorders and to investigate those personality traits that are more frequent in patients with high levels of dissociation. 50 Caucasian females were enrolled in the study. Patients were assessed through the Self-Report Symptom Check-List, the Dissociative Experiences Scale (DES) and rating scales for Depression and Anxiety. The mean DES score in the overall sample was 16.6. 32% of patients had a DES score > 20. Depressive symptoms positively correlated with the DES total scores. Dissociator patients presented some significantly different temperamental characteristics in comparison with non dissociator patients. Dissociative symptoms are highly present in patients with mood and anxiety disorders and correlate with the severity of depressive symptoms. Specific personality traits more frequently observed in dissociator people may represent predisposing factors; their early identification could be clinically relevant.

Based on the personality model outlined by Robert C. Cloninger, studies in adult patient samples demonstrated that according to distinct personality profiles patients with anorexia nervosa could be differentiated from those with bulimia nervosa, as well as from healthy controls. The current study examines whether these personality-related differences also exist in adolescent patients with eating disorders and a short duration of illness. The sample studied consists of 73 consecutively admitted female patients aged 12 to 18 years, with eating disorders. The German version of the Junior Temperament and Character Inventory (JTCI) was administered to 29 patients with anorexia nervosa, restricting type (AN-R), to 16 patients with anorexia nervosa, binge-eating/purging type (AN-B), and to 28 patients with bulimia nervosa (BN). Different temperamental factors were most pronounced between AN-R and BN patients, whereas AN-B patients exhibited a personality profile between those of AN-R and BN. BN patients scored higher on Novelty Seeking but lower on Persistence than AN-R patients. In contrast to AN-R patients, both BN and AN-B patients scored lower on Self-Directedness. The current results of differential temperamental dimensions in adolescent patients with eating disorders tended to be similar to findings for adult patients, which strengthens the assumption that distinct personality factors underlie the different subtypes of eating disorders.

The current study examined whether autobiographical memories from parents' own childhoods, prebirth expectations, and personality traits contributed to their perceptions of their infants' temperament. It also investigated whether mothers and fathers differed in the extent to which these three sources of subjectivity predicted their perceptions. During the third trimester of pregnancy, expectant mothers and fathers in 96 families completed assessments of their personality traits and expectations for their children's temperament, as well as provided characteristic memories of their relationships with their own caregivers as children. Memories were then coded for themes of growth versus safety and compared to parents' ratings of perceived child temperament 15 months later. Analyses revealed that, for both parents, prebirth expectations predicted perceptions of positive temperament behaviors. Moreover, fathers who described childhoods characterized by exploration and opportunities for growth also perceived their children as displaying more positive temperamental behaviors, whereas those who described greater safety focus in memories and who had higher levels of negative affectivity reported more negative temperamental behaviors. These findings suggest that mothers' and fathers' perceptions of their children are differently related to psychological variables, including autobiographical memories. In turn, it is possible that these subjective perceptions may affect the parenting environment. Copyright © 2016 Elsevier Inc. All rights reserved.

Adolescent alcohol use is common and has serious immediate and long-term ramifications. While concurrent individual and context factors are robustly associated with adolescent alcohol use, the influence of early childhood factors, particularly in interaction with child sex, are less clear. Using a prospective community sample of 362 (190 girls), this study investigated sex differences in the joint influence of distal childhood and proximal adolescent factors on Grade 10 alcohol use. All risk factors and two-way early individual-by-context interactions, and interactions of each of these with child sex, were entered into the initial regression. Significant sex interactions prompted the use of separate models for girls and boys. In addition to the identification of early (family socioeconomic status, authoritative parenting style) and proximal adolescent (mental health symptoms, deviant friends) risk factors for both girls and boys, results highlighted important sex differences. In particular, girls with higher alcohol consumption at Grade 10 were distinguished by the interaction of early temperamental disinhibition and exposure to parental stress; boys with higher alcohol consumption at Grade 10 were distinguished primarily by early temperamental negative affect. Results have implications for the timing and type of interventions offered to adolescents.

2002-04-01

Our objective was to test the hypothesis that temperamental behavioral disinhibition measured in early childhood would be associated with disruptive behavior disorders. We used variables from laboratory-based behavioral observations originally devised to assess behavioral inhibition to construct a theory-based a priori definition of "behavioral disinhibition" in 200 young children at-risk for panic disorder, depression, or both and 84 children of parents without anxiety or major depressive disorder. We then compared behaviorally disinhibited and nonbehaviorally disinhibited children on rates of DSM-III-R disorders and measures of academic and social dysfunction. Behavioral disinhibition was significantly associated with higher rates of disruptive behavior disorders and mood disorders. Children with behavioral disinhibition were significantly more likely than nondisinhibited, noninhibited children to have attention-deficit/hyperactivity disorder (ADHD) and to have comorbid mood and disruptive behavior disorders. Moreover, disinhibited children had lower Global Assessment of Functioning Scale scores and were more likely to have been in special classes and to have problems with school behavior and leisure activities. These results suggest that behavioral disinhibition may represent a temperamental precursor to disruptive behavior problems, particularly ADHD. Longitudinal studies using behavioral assessments of behavioral disinhibition are needed to confirm these findings.

Although there is great interest in identifying the neural correlates of cognitive processes that create risk for psychopathology, there is a paucity of research in young children. One event-related potential (ERP), the N2, is thought to index conflict monitoring and has been linked cognitive and affective risk factors for anxiety. Most of this research, however, has been conducted with adults, adolescents, and older children, but not with younger children. To address this gap, the current study examined 26 4-8-year-olds, who completed a cued flanker task while EEG was continuously recorded. We assessed whether the N2 was detectable in this group of young children and examined associations between the N2 and factors reflecting affective risk (e.g., reduced executive attention, temperamental effortful control, and temperamental surgency). We documented an N2 effect (greater N2 amplitude to incongruent versus congruent flankers), but only in children older than 6 years of age. Increases in the N2 effect were associated with less efficient executive attention and lower temperamental effortful control. We discuss the implications of these findings and consider how they may inform future studies on biomarkers for cognitive and affective risk factors for anxiety.

Avoidant personality disorder versus social phobia: the significance of childhood neglect.

2015-01-01

Avoidant personality disorder (AvPD) and social phobia (SP) are common disorders both in the community and in clinical settings. Whether the two disorders represent different severity levels of social anxiety disorder is currently in dispute. The relationship between AvPD and SP is probably more complex than previously assumed. Several environmental, temperamental, and constitutional factors may play a role in the etiology of AvPD and SP. Better knowledge about childhood experiences may shed light on similarities and differences between the two disorders. The aim of this study was to compare self-reported childhood experiences in AvPD and SP patients. This is a cross-sectional multi-site study of 91 adult patients with AvPD and/ or SP. We compared patients with AvPD with and without SP (AvPD group) to patients with SP without AvPD (SP group). The patients were examined using structured diagnostic interviews and self-report measures, including Child Trauma Questionnaire, Parental Bonding Instrument, and Adult Temperament Questionnaire. Both AvPD and SP were associated with negative childhood experiences. AvPD patients reported more severe childhood neglect than patients with SP, most pronounced for physical neglect. The difference between the disorders in neglect remained significant after controlling for temperamental factors and concurrent abuse. The study indicates that childhood neglect is a risk factor for AvPD and may be one contributing factor to phenomenological differences between AvPD and SP.

Developmental Origins of Rumination in Middle Childhood: The Roles of Early Temperament and Positive Parenting.

Rumination, a thinking style characterized by a repetitive inward focus on negative cognitions, has been linked to internalizing disorders, particularly depression. Moreover, research suggests that rumination may be a cognitive vulnerability that predisposes individuals to psychopathology. Surprisingly little is known, however, about the etiology and development of rumination. The present study examined the role of specific components of child temperamental negative emotionality (sadness, fear, anger) and effortful control (inhibition), as well as parenting behaviors during early childhood on the development of rumination in middle childhood. Early childhood (age 3) temperament and parenting behaviors were assessed observationally and rumination was self-reported in middle childhood (age 9) in a large community sample (N = 425; 47.1% female). Two significant interactions emerged. First, temperamental anger interacted with inhibitory control (IC) such that high anger and low IC predicted higher levels of rumination, whereas low anger and low IC predicted lower levels of rumination. Second, IC interacted with parenting such that children with low IC and positive parenting had lower levels of rumination. In contrast, children with high IC reported similar levels of rumination regardless of parenting quality. Overall, these findings highlight the interplay of early IC with temperamental anger and positive parenting in the development of ruminative tendencies in middle childhood.

Internationally adopted children from non-European countries: general development during the first two years in the adoptive family.

Dalen, Monica; Theie, Steinar

2012-01-01

Internationally adopted children are often delayed in their development and demonstrate more behaviour problems than nonadopted children due to adverse preadoption circumstances. This is especially true for children adopted from Eastern European countries. Few studies have focused on children adopted from non-European countries. This paper presents results from an ongoing longitudinal study of 119 internationally adopted children from non-European countries during their first two years in Norway. Several scales measuring different aspects of the children's development are included in the study: communication and gross motor development, temperamental characteristics, and behaviour problems. The results show that internationally adopted children are delayed in their general development when they first arrive in their adoptive families. After two years the children have made significant progress in development. However, they still lag behind in communication and motor skills compared to non-adopted children. The temperamental characteristics seem very stable from time of adoption until two years after adoption. The children demonstrate a low frequency of behaviour problems. However, the behaviour problems have changed during the two years. At time of adoption they show more nonphysically challenging behaviour while after two years their physically challenging behaviour has increased.

Earlier use of tobacco in adolescence is associated with numerous adverse outcomes later in life. Although a number of studies have linked individual differences in affective functioning to adolescent smoking, these have relied primarily on self-report measures, and the contribution of different dimensions of affect to the onset of tobacco use during this period remains unclear. The current study examined these issues in a sample of 180 adolescents recruited from an ongoing prospective, longitudinal study examining emotional development. At approximately age 12, participants completed a questionnaire measure of affective temperament and took part in a family interaction task that was coded observationally to provide measures of dysphoric, aggressive, and positive behaviors. At 2 subsequent assessments, which took place approximately 2.5 years and 4 years after the initial assessment, participants completed a questionnaire measure of substance use. In total, 70 participants initiated smoking between the ages of 12 and 17. An earlier onset of smoking was predicted by more aggressive and less positive observed behavior during the interaction task, as well as lower levels of self-reported temperamental Effortful Control. There were no associations between dysphoric behaviors, or temperamental measures of negative affectivity or surgency and the onset of smoking. The findings add to a small body of literature demonstrating that behavioral components of affect can prospectively predict substance use in adolescence and suggest that different dimensions of affect show unique relationships with early substance use.

Objective Despite an increasing recognition that psychiatric disorders can be diagnosed as early as preschool, little is known how early genetic and environmental risk factors contribute to the development of psychiatric disorders during this very early period of development. Method We assessed infant temperament at age 1, and attention deficit hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), and separation anxiety disorder (SAD) at ages 3 through 5 years in a sample of Hispanic twins. Genetic, shared, and non-shared environmental effects were estimated for each temperamental construct and psychiatric disorder using the statistical program MX. Multivariate genetic models were fitted to determine whether the same or different sets of genes and environments account for the co-occurrence between early temperament and preschool psychiatric disorders. Results Additive genetic factors accounted for 61% of the variance in ADHD, 21% in ODD, and 28% in SAD. Shared environmental factors accounted for 34% of the variance in ODD and 15% of SAD. The genetic influence on difficult temperament was significantly associated with preschool ADHD, SAD, and ODD. The association between ODD and SAD was due to both genetic and family environmental factors. The temperamental trait of resistance to control was entirely accounted for by the shared family environment. Conclusions There are different genetic and family environmental pathways between infant temperament and psychiatric diagnoses in this sample of Puerto Rican preschool age children. PMID:25728588

This study examined the contribution of child temperament, parenting, and their interaction on inhibitory control development in a sample of maltreated and non-maltreated preschool children. One hundred and eighteen mother–child dyads were drawn from predominantly low-income, rural communities. Dyads participated in a laboratory session in which maternal warm autonomy support, warm guidance, and strict/hostile control were observationally coded during a joint teaching task. Independent assessments of children’s inhibitory control were obtained, and observers rated children’s temperament. After relevant covariates, including income, maternal education, and child age and IQ were controlled for, there were no differences between the maltreatment and non-maltreatment groups in either children’s inhibitory control or mothers’ behaviours in the laboratory session. Even after much of the variance in children’s inhibitory control was accounted for from the covariates, children’s temperamental negativity moderated the effects of warm autonomy support on inhibitory control in both maltreatment and non-maltreatment groups. Temperamentally negative children whose mothers displayed more warm autonomy support showed greater inhibitory control, at levels on par with low-negative children. Findings suggest that heterogeneity in children’s self-regulation may be due in part to individual differences in sensitivity to caregiver support for children’s independence, even among those exposed to maltreatment.

The present study examines the influences of mothers’ emotional availability towards their infants during bedtime, infant attachment security, and interactions between bedtime parenting and attachment with infant temperamental negative affectivity, on infants’ emotion regulation strategy use at 12 and 18 months. Infants’ emotion regulation strategies were assessed during a frustration task that required infants to regulate their emotions in the absence of parental support. Whereas emotional availability was not directly related to infants’ emotion regulation strategies, infant attachment security had direct relations with infants’ orienting towards the environment and tension reduction behaviors. Both maternal emotional availability and security of the mother-infant attachment relationship interacted with infant temperamental negative affectivity to predict two strategies that were less adaptive in regulating frustration.

We tested the structure and magnitude of genetic and environmental influences on the overlap among self-esteem, negative emotionality, and major depression symptoms in adolescent girls (N=706) from the Minnesota Twin Family Study. Genetic and environmental influences on all three operated via a general, heritable factor. Genetic influences explained the majority of overlap among the three constructs, as well as most of the variance in self-esteem and negative emotionality. Genetic influences on depression were more modest and largely due to genetic factors specific to depression. These findings support the theory that self-esteem, depression, and neuroticism represent aspects of a common temperamental core. The interrelations among the three constructs in mid-adolescence is consistent with their interrelations in adulthood.

Substance abuse is among the leading causes of preventable diseases and premature death but reasons and conditions leading to substance abuse are complex and multifaceted. Different models of abuse and dependence assume an underlying emotional vulnerability. Individual behavioral and emotional reactivity patterns of personality are considered in the concept of temperament but studies linking different types of temperament with substance use are rare. In this study we investigated 1380 inhabitants (59.7% females; 40.3% males) of residential student homes in Austria, using Akiskals TEMPS-M auto-questionnaire. Further, we administered the CAGE- and the HSI-questionnaire and assessed other psychoactive substance use to examine associations between traits of temperament and substance abuse using ordered logistic regression. Temperaments follow different distributions in both genders: Women have higher scores on the depressive, cyclothymic, and anxious subscales and lower scores on the hyperthymic scale than men. The cyclothymic and particularly irritable temperament serve as predictors of self-reported nicotine dependence, alcohol abuse and cannabis use. Interestingly, the depressive temperament seems to be protective against self-reported cannabis use. Substance abuse assessment is based on self-reports only and urine drug and blood tests were not performed. Also, the history of substance abuse is not documented thus temperamental factors could have been influenced by substance abuse if the time of onset was in early adolescence. The study design was cross-sectional, thus limiting causal interpretations. It might be important to consider temperamental traits as protective- and risk factors in the etiology, prevention and therapy of substance abuse in future. Copyright © 2012 Elsevier B.V.

Temperament, Speech and Language: An Overview

Conture, Edward G.; Kelly, Ellen M.; Walden, Tedra A.

2013-01-01

The purpose of this article is to discuss definitional and measurement issues as well as empirical evidence regarding temperament, especially with regard to children's (a)typical speech and language development. Although all ages are considered, there is a predominant focus on children. Evidence from considerable empirical research lends support to the association between temperament, childhood development and social competence. With regard to communication disorders, extant literature suggests that at least certain elements of temperament (e.g., attention regulation, inhibitory control) are associated with the presence of certain communication disorders. However, the precise nature of this association remains unclear. Three possible accounts of the association between temperament and speech-language disorder are presented. One, the disability model (i.e., certain disorders impact psychological processes leading to changes in these processes, personality, etc., Roy & Bless, 2000a) suggests speech-language disorders may lead to or cause changes in psychological or temperamental characteristics. The disability account cannot be categorically refuted based on currently available research findings. The (pre)dispositional or vulnerability model (i.e., certain psychological processes directly cause the disorder or indirectly modify the course or expression of the disorder, Roy & Bless, 2000a) suggests that psychological or temperamental characteristics may lead to or cause changes in speech-language disorders. The vulnerability account has received some empirical support with regard to stuttering and voice disorders but has not received widespread empirical testing for most speech-language disorders. A third, interaction account, suggests that “disability” and ““vulnerability” may both impact communication disorders in a complex, dynamically-changing manner, a possibility that must await further empirical study. Suggestions for future research directions are provided. PMID:23273707

Previous research suggests high levels of comorbidity between social phobia and paranoid symptoms, although the nature of this association remains unclear. Data were derived from the Early Developmental Stages of Psychopathology study, a 10-year longitudinal study in a representative German community sample of 3021 participants aged 14-24 years at baseline. The Munich-Composite International Diagnostic Interview was used to assess social phobia and paranoid symptoms, along with data on social phobia features. Cross-sectional and longitudinal analyses were conducted. Differential associations with environmental risk factors and temperamental traits were investigated. Lifetime social phobia and paranoid symptoms were associated with each other cross-sectionally (OR = 1.80, 95% CI = 1.31-2.47). Lifetime paranoid symptoms were associated specifically with social anxiety cognitions. Lifetime cognitions of negative evaluation predicted later onset of paranoid symptoms, whereas onset of social phobia was predicted by cognitions of loss of control and fear/avoidance of social situations. Lifetime social phobia and paranoid symptoms shared temperamental traits of behavioural inhibition, but differed in environmental risks. The present study showed that paranoid symptoms and social phobia share similarities in cognitive profile and inhibited temperament. Avoidance appears to be important in the development of social phobia, whereas cannabis use and traumatic experiences may drive paranoid thinking in vulnerable individuals. © 2011 John Wiley & Sons A/S.

Background The connection between psychopathology and tinnitus is complex and not adequately studied. The aim of this study is to investigate the relationship between tinnitus and psychiatric comorbidities from different points of view: categorical, dimensional, temperamental, and perceived stress level. Methods Two hundred and thirty-nine patients affected by tinnitus were recruited between January and October 2012. Patients underwent a preliminary battery of tests including the Tinnitus Handicap Inventory (THI), Symptom Check List (SCL90-R), Temperament and Character Inventory (TCI), and Stress-Related Vulnerability Scale (VRS), and eventually a full psychiatric evaluation. Results One hundred and fourteen patients (48% of the total sample) presented psychiatric comorbidity. Among these, a higher prevalence of depression, somatization, obsession, and anxiety was found. More than 41% of patients affected by decompensated tinnitus reported a family history of psychiatric disorders. Significant positive correlations between the psychopathological screening tools (SCL90-R and VRS) and THI were found. Patients affected by comorbid psychiatric disorder showed specific temperamental and characterial predispositions. Conclusion Psychiatric comorbidity in subjects affected by tinnitus is frequent. Stress can be considered as a factor leading to damage and dysfunction of the auditory apparatus. The vulnerability to neurotic disorders and the lack of coping capabilities can play a critical role in the clinical history of patients affected by severe tinnitus. PMID:24550676

Temperament, Emotion and Childhood Stuttering

Jones, Robin; Choi, Dahye; Conture, Edward; Walden, Tedra

2015-01-01

The purpose of this article is to provide a brief description of temperament and emotion, review empirical evidence pertaining to their possible association with childhood stuttering, and discuss possible clinical implications. In general, temperament is typically thought of as an individual's constitutionally (biologically) based behavioral proclivities. These proclivities often include emotional reactivity and self-regulation. Reactivity refers to arousal of emotions, motor activity, and attention, and self-regulation refers to the ability to moderate those tendencies. The trait-like nature of temperament makes it potentially salient to our understanding of the onset and development of stuttering because temperamental tendencies may result in greater reactivity or difficulty in coping. Emotions, which are more state-like and variable, may influence the variation of stuttering commonly observed both within and between speaking situations. Temperament and emotion may serve as a causal contributor to developmental stuttering, with empirical findings indicating that preschool-aged children who stutter (CWS) exhibit differences in temperament and emotion when compared with children who do not stutter (CWNS). Given that empirical study of temperament in preschool-aged CWS is nascent, extensive discussion of clinical implications is challenging. With that caution, we present some early possibilities, including matching treatment approaches with the child's temperamental profile and using temperament as a predictor of treatment outcome.

2013-01-01

This study presents a novel task examining young children’s affective responses to evaluative feedback—specifically, social acceptance and rejection—from peers. We aimed to determine (1) whether young children report their affective responses to hypothetical peer evaluation predictably and consistently, and (2) whether young children’s responses to peer evaluation vary as a function of temperamental shyness and gender. Four- to seven-year-old children (N = 48) sorted pictures of unknown, similar-aged children into those with whom they wished or did not wish to play. Computerized peer evaluation later noted whether the pictured children were interested in a future playdate with participants. Participants then rated their affective responses to each acceptance or rejection event. Children were happy when accepted by children with whom they wanted to play, and disappointed when these children rejected them. Highly shy boys showed a wider range of responses to acceptance and rejection based on initial social interest, and may be particularly sensitive to both positive and negative evaluation. Overall, the playdate task captures individual differences in affective responses to evaluative peer feedback and is potentially amenable to future applications in research with young children, including pairings with psychophysiological measures.

This study examined specific forms of emotional reactivity to conflict and temperamental emotionality as explanatory mechanisms in pathways among interparental aggression and child psychological problems. Participants of the multi-method, longitudinal study included 201 two-year-old children and their mothers who had experienced elevated violence in the home. Consistent with emotional security theory, autoregressive structural equation model analyses indicated that children’s fearful reactivity to conflict was the only consistent mediator in the associations among interparental aggression and their internalizing and externalizing symptoms one year later. Pathways remained significant across maternal and observer ratings of children’s symptoms and with the inclusion of other predictors and mediators, including children’s sad and angry forms of reactivity to conflict, temperamental emotionality, gender, and socioeconomic status.

2015-01-01

From the 1990s, extensive research was started on the physiological aspects of individual traits in animals. Previous research has established two extreme (proactive and reactive) coping styles in several animal species, but the means of reactivity with the autonomic nervous system (ANS) activity has not yet been investigated in cattle. The aim of this study was the characterization of cardiac autonomic activity under different conditions in cows with different individual characteristics. For this purpose, we investigated heart rate and ANS-related heart rate variability (HRV) parameters of dairy cows (N = 282) on smaller- and larger-scale farms grouped by (1) temperament and (2) behavioural reactivity to humans (BRH). Animals with high BRH scores were defined as impulsive, while animals with low BRH scores were defined as reserved. Cardiac parameters were calculated for undisturbed lying (baseline) and for milking bouts, the latter with the presence of an unfamiliar person (stressful situation). Sympathetic tone was higher, while vagal activity was lower in temperamental cows than in calm animals during rest both on smaller- and larger-scale farms. During milking, HRV parameters were indicative of a higher sympathetic and a lower vagal activity of temperamental cows as compared to calm ones in farms of both sizes. Basal heart rate did not differ between BRH groups either on smaller- or larger-scale farms. Differences between basal ANS activity of impulsive and reserved cows reflected a higher resting vagal and lower sympathetic activity of reserved animals compared to impulsive ones both on smaller- and larger-scale farms. There was no difference either in heart rate or in HRV parameters between groups during milking neither in smaller- nor in larger-scale farms. These two groupings allowed to draw possible parallels between personality and cardiac autonomic activity during both rest and milking in dairy cows. Heart rate and HRV seem to be useful for characterisation of physiological differences related to temperament and BRH. PMID:26291979

Difficult temperament in infancy is a risk factor for forms of later internalizing and externalizing psychopathology, including depression and anxiety. A better understanding of the roots of difficult temperament requires assessment of its early development with a genetically informative design. The goal of this study was to estimate genetic and environmental contributions to individual differences in infant negative emotionality, their persistence over time and their influences on stability between 5 and 18 months of age. Participants were 244 monozygotic and 394 dizygotic twin pairs (49.7% male) recruited from birth. Mothers rated their twins for negative emotionality at 5 and 18 months. Longitudinal analysis of stability and innovation between the two time points was performed in Mplus. There were substantial and similar heritability (approximately 31%) and shared environmental (57.3%) contributions to negative emotionality at both 5 and 18 months. The trait's interindividual stability across time was both genetically- and environmentally- mediated. Evidence of innovative effects (i.e., variance at 18 months independent from variance at 5 months) indicated that negative emotionality is developmentally dynamic and affected by persistent and new genetic and environmental factors at 18 months. In the first two years of life, ongoing genetic and environmental influences support temperamental negative emotionality but new genetic and environmental factors also indicate dynamic change of those factors across time. A better understanding of the source and timing of factors on temperament in early development, and role of sex, could improve efforts to prevent related psychopathology.

Temperament and the environment in the etiology of childhood anxiety

Degnan, Kathryn A.; Almas, Alisa N.; Fox, Nathan A.

2010-01-01

Anxiety disorders are prevalent throughout childhood and adolescence. As such, identifying the factors and mechanisms that precede, maintain, or exacerbate anxiety disorders is essential for the development of empirically-based prevention and intervention programs. The current review focuses on child temperament (i.e., behavioral inhibition) and the child’s environment, including parenting, child care, and peer relationships, as these factors have been linked to internalizing problems and anxiety diagnoses. Research programs are needed that examine the associations between the environment and anxiety in temperamentally at-risk populations. In order to be successful, early intervention and prevention programs require a more detailed analysis of the interplay between various environmental contexts, both distal and proximal to the child, and the child’s temperamental reactivity to novelty and threat. Furthermore, conducting these investigations across multiple levels of analysis in large-scale, longitudinal samples would be an important addition to the literature on the developmental psychopathology of anxiety.

This study examined how child temperament was related to parents’ time spent accessible to and interacting with their 2-year-olds. Bivariate analyses indicated that both fathers and mothers spent more time with temperamentally challenging children than easier children on workdays, but fathers spent less time with challenging children than easier children on non-workdays. After accounting for work hours, some associations between temperament and fathers’ workday involvement dropped to non-significance. For fathers, work hours also moderated the relation between irregular temperament and workday play. For mothers, work hours moderated the relation between both difficult and irregular temperament and workday interaction. Mothers also spent more time with girls (but not boys) who were temperamentally irregular. Results speak to the influence of child temperament on parenting behavior, and the differential construction of parenting roles as a function of child characteristics and patterns of work.

Previous studies suggest that temperamental dispositions are associated with substance use. However, most research supporting this association has relied on European American samples (Stautz & Cooper, 2013). We addressed this gap by evaluating the prospective relations between 5th grade temperament and 9th grade substance use in a longitudinal sample of Mexican-origin youth (N = 674). Effortful control and trait aggressiveness predicted 9th grade substance use, intentions, and expectations, even after controlling for 5th grade substance use. Additionally, we found an interaction between temperament and parental monitoring such that monitoring is a protective factor for early substance use primarily for youth with temperamental tendencies associated with risk for substance use (e.g., low effortful control and aggression). Results add to the growing literature demonstrating that early manifestations of self-control are related to consequential life outcomes. PMID:25841175

The development of leisure boredom in early adolescence: Predictors and longitudinal associations with delinquency and depression.

PubMed

Spaeth, Michael; Weichold, Karina; Silbereisen, Rainer K

2015-10-01

The literature proposes that leisure boredom may systematically increase during adolescence. Moreover, some authors assume that this hypothesized developmental trend is associated with increases in youthful delinquency and depression. Individual dispositions (e.g., temperamental disinhibition) are believed to exacerbate the relationship between boredom and delinquency. This study investigated whether (1) leisure boredom really is an increasing phenomenon during early adolescence; (2) gender, temperamental disinhibition, shyness, family relationship quality, peer rejection, a deprived school context, and rural/urban living explain developmental variations in boredom; (3) boredom is longitudinally and reciprocally related to delinquency and depression; and (4) bored disinhibited adolescents are particularly likely to become delinquent and to use delinquent acts to mitigate boredom. Analyses were based on a German sample of school students (N = 722) who provided annual self-reports on study variables from age 10 to 14 years. Bivariate growth curve models captured correlations between developmental trajectories of boredom and delinquency/depression. Cross-lagged models examined reciprocal short-term associations. Analyses revealed a modest increase in leisure boredom during early adolescence. Disinhibition and qualities of proximal social contexts (family, peers, school) were related to boredom with peer rejection showing the most consistent longitudinal association. Boredom was developmentally associated with depression whereas longitudinal associations with delinquency were weaker and more short-term. Temperamentally disinhibited adolescents appeared to buffer leisure boredom by means of delinquency. Results support person-context models of leisure boredom with regard to its etiology and consequences. Findings further demonstrate that leisure boredom plays a prominent role in the developmental adaptation of adolescents. (c) 2015 APA, all rights reserved).

Behavioral observations of positive and negative valence systems in early childhood predict physiological measures of emotional processing three years later.

The Research Domain Criteria (RDoC) constructs of Positive Valence Systems (PVS) and Negative Valence Systems (NVS) are presumed to manifest behaviorally through early-emerging temperamental negative affectivity (NA) and positive affectivity (PA). The late positive potential (LPP) is a physiological measure of attention towards both negative and positive emotional stimuli; however, its associations with behavioral aspects of PVS and NVS have yet to be examined. In a community sample of children (N = 340), we examined longitudinal relationships between observational measures of temperamental PA and NA assessed at age 6, and the LPP to both pleasant and unpleasant images assessed at age 9. Lower PA at age 6 predicted reduced LPP amplitudes to pleasant, but not unpleasant, images. NA as a composite measure was not related to the LPP, but specific associations were observed with facets of NA: greater fear predicted an enhanced LPP to unpleasant images, whereas greater sadness predicted a reduced LPP to unpleasant images. We were unable to evaluate concurrent associations between behavioral observations of temperament and the LPP, and effect sizes were modest. Results support correspondence between behavioral and physiological measures of emotional processing across development, and provide evidence of discriminant validity in that PA was specifically related to the LPP to pleasant images, while facets of NA were specifically linked to the LPP to unpleasant images. Distinct associations of temperamental sadness and fear with the LPP highlight the importance of further evaluating subconstructs of NVS. Copyright © 2016 Elsevier B.V. All rights reserved.

Joint Contributions of Negative Emotionality, Positive Emotionality, and Effortful Control on Depressive Symptoms in Youth.

2016-11-02

From a clinical developmental perspective, temperament has been shown to confer vulnerability to depression among youth. High negative emotionality (NE), low positive emotionality (PE), and low effortful control (EC) have repeatedly been independently associated with youth depressive symptoms. However, far less research has examined the joint contributions of NE, PE, and EC on such symptoms. The present study builds upon previous research by examining how NE, PE, and EC jointly predict change in depressive symptoms over time among 211 youngsters (7-14 years, M = 10.7, SD = 1.81) who participated in an 8-month prospective study. Self-reported temperament and symptoms were assessed at baseline; self-reported symptoms were measured again at follow-up. Results suggest that all 3 temperamental traits need to be considered jointly in predicting change in depressive symptoms. Furthermore, results provide further support for the "best two out of three" principle. Surprisingly, results reveal that high EC might be maladaptive in the context of high emotional reactivity. Last, results show that the combination of high NE and low EC could be a possible pathway to the development of symptoms. The current study clarified how NE, PE, and EC may jointly confer risk-or protection for developing depressive symptoms during adolescence. The results highlight the need of taking into account all three temperamental traits in order to provide a more nuanced understanding of the risk for developing depressive symptoms at an early stage, as well as to provide customized care targeting temperamental vulnerability in depressed youth.

Young Children’s Self-Concepts: Associations with Child Temperament, Mothers’ and Fathers’ Parenting, and Triadic Family Interaction

This study explored how children’s self-concepts were related to child temperament, dyadic parenting behavior, and triadic family interaction. At age 3, child temperament, mothers’ and fathers’ parenting behavior, and triadic (mother, father, and child) family interaction were observed in the homes of fifty families. At age 4, children’s self-concepts were assessed using the Children’s Self-View Questionnaire (Eder, 1990). Analyses revealed that temperamental proneness-to-distress and triadic family interaction made independent contributions to children’s self-reported Timidity and Agreeableness. In contrast, dyadic parenting behavior moderated the associations between child temperament and children’s self-reported Timidity and Agreeableness, such that temperament was only associated with children’s self-concepts when mothers and fathers engaged in particular parenting behaviors. Results suggest both direct and interactive influences of family dynamics and child characteristics on children’s self-concept development. PMID:25983365

The aim of this study was to characterise the temperament of combat athletes in comparison to that of individuals who do not practise any sports with regard to pain sensitivity measured with the cold pressor test (CPT) and pressure pain threshold (PPT). The study involved 284 healthy men, aged 18 to 43years. The first group consisted of 198 combat athletes, including boxing (n=19), mixed martial arts (MMA) (n=97) and karate (n=82), aged from 18 to 43years. The control group consisted of 86 subjects between the ages of 18 and 26years, academic students not practising any sport professionally. Pain threshold and pain tolerance were evaluated using the CPT and a pressure algometer. Temperament was measured with the Formal Characteristics of Behaviour - Temperament Inventory (FCB-TI). The contact athletes showed much higher tolerance to pain than the control group using both tools: CPT (p=0.007) and PPT (p<0.001). In athletes, but not in controls, relationships were noted between BMI and endurance (r=0.20; p=0.004), BMI and activity (r=-0.283; p<0.001), BMI and pain threshold (r=0.15; p<0.05), and BMI and pain tolerance (r=0.30; p<0.001), when measured by the algometer - this necessitating adjustment for further analysis. The athletes and students in the study groups differed significantly with regard to intensity of four temperamental traits, but after BMI adjustments only group differences in Preservation, Sensory sensitivity and Emotional reactivity remained significant'. These differences indicate individual differences in perception and reaction to external stimuli. Significantly higher pain tolerance (CPT and PPT) in the athletes studied was related to specific psychological features. The obtained results of temperamental characteristics may indicate higher resilience of the nervous system in combat athletes in comparison to non-athletes. Copyright © 2017 Elsevier Inc.

Gibbs, Benjamin G; Forste, Renata; Lybbert, Emily

Objectives Infants and toddlers need secure attachments in order to develop the social competence required to successfully navigate later peer and adult relationships. Breastfeeding is a parenting factor that has been associated with child emotional development-specifically the attachment between children and their mothers. Yet, this link may simply be the result of other parenting behaviors that are associated with breastfeeding. Thus, our objective is to examine whether the link between infant attachment behaviors and breastfeeding endures when accounting for a broad array of in-depth measures of parenting. Methods We use the Early Childhood Longitudinal Study of children from 9 months to 2 years of age collected by the National Center for Education Statistics. Using Ordinary Least Squares regression, data analyses examine the association between the Toddler Attachment Sort-45 (TAS-45) measures of toddler-parent attachment (infant attachment security and temperamental dependency) and breastfeeding practices. We also examine individual items of the TAS-45 to isolate specific attachment behaviors that have the strongest associations with breastfeeding. Results We find an enduring link between children who are predominantly breastfed for six or more months and infant attachment security. However, we find no evidence that breastfeeding is linked to a child's temperamental dependency. Of the nine items used to examine infant attachment behaviors, we find that breastfed children are rated as having slightly higher scores on two measures ("warm and cuddly," "cooperative") and lower scores on one measure ("demanding/angry"). Conclusions for Practice Breastfeeding has an important link to the child's use of their caregiver as a secure base for exploration and a place of comfort when distressed (infant attachment security). Yet, breastfeeding does not appear to reduce a child's temperamental dependency or level of clinginess as measured by how demanding, fussy or distressed the child becomes when separated.

Most studies on temperamental and behavioral/emotional characteristics of oppositional defiant disorder (ODD) did not rule out the effect of comorbid attention-deficit/hyperactivity disorder (ADHD). The main objective of this study was to identify the temperamental and psychopathological patterns of ODD independent of comorbid ADHD. We also aimed to compare the patterns of temperament and psychopathology between ODD with and without ADHD. Parents of 2673 students, randomly selected from 19 representative schools in Seoul, Korea, completed the Diagnostic Interview Schedule for Children Version IV. Among 118 children and adolescents with ODD diagnosed by the Diagnostic Interview Schedule for Children Version IV, the parents of 94 subjects (mean age, 10.4 +/- 3.0 years) and the parents of a random sample of 94 age- and gender-matched non-ODD/non-ADHD children and adolescents completed the parent's version of the Child Behavior Checklist (CBCL) and the Junior Temperament and Character Inventory. Subjects with ODD showed temperament and character profiles of high Novelty Seeking, low Self-directedness, and low Cooperativeness, a distinct pattern on the CBCL, and were at increased risk for anxiety and mood disorders compared to the controls after controlling for the effect of comorbid ADHD. The children and adolescents with both ODD and ADHD showed decreased levels of Persistence and Self-directedness and higher scores on 4 subscales of the CBCL (Anxious/Depressed, Attention Problems, Delinquent Behaviors, and Aggressive Behaviors) compared to those with ODD only. Oppositional defiant disorder is associated with specific temperamental and behavioral/emotional characteristics, independent of ADHD. Moreover, the results of this study support that co-occurring ADHD and ODD have differentially higher levels of behavioral and emotional difficulties. Copyright 2010 Elsevier Inc.

Maternal stress is associated with impairments in the neurodevelopment of offspring; however, the effects of the timing of exposure to maternal stress on a child's neurodevelopment are unclear. In 2010, we studied 225 mother-child pairs in Shanghai, recruiting mothers in mid-to-late pregnancy and monitoring offspring from birth until 30 months of age. Maternal stress was assessed prenatally (at 28-36 weeks of gestation) and postnatally (at 24-30 months postpartum) using the Symptom-Checklist-90-Revised Scale (SCL-90-R) and Life-Event-Stress Scale to evaluate mothers' emotional stress and life event stress levels, respectively. Children's cognition and temperament were assessed at 24-30 months of age using the Gesell Development Scale and Toddler Temperament Scale, respectively. Multi-variable linear regression models were used to associate prenatal and postnatal stress with child cognitive and temperamental development. Maternal prenatal and postnatal Global Severity Index (GSI) of SCL-90-R were moderately correlated (ICC r=0.30, P<0.001). After adjusting for relevant covariates, the increase in prenatal GSI was associated with decreases in toddlers' gross motor, fine motor, adaptive and social behavior development independently of postnatal GSI, while the increase in postnatal GSI was associated with changes in multiple temperament dimensions independently of prenatal GSI. The effects of prenatal and postnatal depression scores of SCL-90-R were similar to those of GSI. Relatively small sample size. Compared with postnatal exposure, children's cognitive development may be more susceptible to prenatal exposure to maternal emotional stress, whereas temperamental development may be more affected by postnatal exposure to maternal emotional stress compared with prenatal exposure.

Temperament refers to the totality of individual characteristics present from birth that determine a child's unique style of behavior. Maternal personality and attitudes, one of the factors affecting temperament traits in children, is a frequently investigated subject. However, paternal variables have remained insufficiently studied. The purpose of this study is to investigate the associations between the fathers' temperament, character, attitudes, psychopathology and temperament of the 3-6 years-old children. The parents of 36-60 months-old children in the preschool settings in Samsun were included in the study (n:200). Their mothers completed "Maternal Sociodemographic Form" prepared by the researcher, and the temperament of children "Children Behaviour Questionnare" were scored by the mothers. Their fathers completed "Paternal Sociodemographic Form", and to assess father psychopathology "Brief Symptom Inventory", to determine father temperament and character "Temperament and Character Inventory" and to determine attitudes "Parenting Attitudes Scale" were scored by the fathers. In this study, we found several significant associations between children's temperament and fathers temperament and character, attitudes styles and psychopathology. The scores of paternal harm avoidance increase and self directedness decrease were found to be significantly positivily correlated with negative temperamental charecteristics of the children. The democratic attitudes of fathers were significantly correlated with positive temperamental scores of the children. All domains of paternal psychopathology were found to be in significant association with negative temperamental characteristics of the children. Our findings showed the complex interplay between determinants of parenting. Specifically, this study is one of the first to investigate paternal personality, psychopathology and attitudes, alone and in interaction with preschool child temperament.

Low positive emotionality (PE) represents a temperamental vulnerability to depression in youth. Until now, little research has examined the mechanisms linking PE to depressive symptoms. Starting from integrated cognitive-affective models of depression, we aimed to study adaptive emotion regulation (ER) as a key underlying mechanism in the temperament-depression relationship. This study investigated whether adaptive ER strategies mediate the association between PE and depressive symptoms in a large community-based sample of youth, using a cross-sectional design. Participants were 1,655 youth (54% girls; 7-16 years, M = 11.41, SD = 1.88) who filled out a set of questionnaires assessing temperament, adaptive ER strategies, and depressive symptoms. Results revealed that low PE was significantly related to higher depressive symptoms among youth and that a lack of total adaptive ER abilities mediated this relationship. More specifically, the infrequent use of problem-solving appeared to be of significant importance. Problems in positive refocusing and a deficient use of forgetting mediated the relationships between low PE and high negative emotionality (NE) in predicting depressive symptoms. Reappraisal and distraction were not significant mediators. Results highlight the need to account for temperamental PE and adaptive ER strategies when studying youth depression. The findings contribute to a more nuanced understanding on the differential role of temperamental risk factors for developing depressive symptoms at an early stage and advocate for greater attention to adaptive ER strategies. Clinical interventions for youth depression may be improved by incorporating adaptive emotion regulation (ER) strategies and enhancing positive emotions. Youth low in positive emotionality (PE) may especially benefit from learning adaptive ER skills. Clinical practitioners should focus on alleviating negative emotions and enhancing positive emotions, especially among youth low in PE. © 2017 The British Psychological Society.

We investigated the effect of co-morbid bipolar disorder and bulimia on temperamental dimensions measured by TEMPS-A, relative to "pure" bulimia and "pure" bipolar disorder, in female patients. The study was performed on 47 patients with bipolar disorder (BD) with a mean age of 36±10 years, 96 patients with bulimia or bulimic type of anorexia, mean age 26±9 years and 50 control healthy females (HC), mean age 29±6 years. Among bulimic patients, a group of 68 subjects with co-morbid bulimia with bipolarity (BD+B) was identified, based on positive score of the Mood Disorder Questionnaire (MDQ). The TEMPS-A questionnaire, 110 questions version, has been used, evaluating five temperament domains: depressive, cyclothymic, hyperthymic, irritable and anxious. Parametric analysis was performed for 4 groups (BD, "pure" bulimia (PB), BD+B and HC), with 28 subjects randomly chosen from each group, using analysis of variance and cluster analysis. All clinical groups significantly differed from control group by having higher scores of depressive, cyclothymic, irritable and anxious temperaments and lower of hyperthymic one. Among patients, significantly higher scores of cyclothymic and irritable temperaments were found in BD+B compared to both PB and BD. These differences were also reflected in cluster analysis, where two clusters were identified. Bipolarity in bulimic patients assessed only by the MDQ. These results show that co-morbid bulimia and bipolar disorder is characterized by extreme dimensions of both cyclothymic and irritable temperaments, significantly higher than each single diagnosis. Possible clinical implications of such fact are discussed. Copyright © 2014 Elsevier B.V. All rights reserved.

Depression and anxiety are the most common mental health problems among women, with various negative impacts both for the women concerned and their families. Greater understanding of developmental trajectories of maternal symptoms of depression and anxiety over the child rearing period would have significant benefits for public health, informing prevention and treatment approaches. The aim of the current study was to examine whether stressors related to child rearing and living conditions, social support, and maternal temperament, predicted mothers' membership in groups with different trajectories of symptoms of depression and anxiety during 13 years of the child rearing phase. The data were from a prospective, longitudinal study of 913 mothers in Norway followed from when their children were 18 months old (time 1) until they were 14.5 years (time 6) (the TOPP study). Multinomial logistic regression analyses were used to test whether child related stressors, stressors related to the living conditions, social support and maternal temperament at time 1 predicted membership in groups based on maternal symptoms of depression and anxiety over the subsequent 13 years. Temperamental distress, followed by child related stressors, were the strongest predictors of membership in a group with high symptoms of depression and anxiety over time. Stressors related to living conditions, and social support from partner and friends/family were also significant predictors. No interaction effects among predictors were found. This study indicates that factors present early in the child rearing phase may provide substantial prediction of the variance in maternal symptoms of depression and anxiety over the following 13 years. Temperamental distress and child related stressors were the strongest predictors of membership in different depression and anxiety symptom trajectory groups.

Background Understanding the dynamics of the gut-brain axis has clinical implications for physical and mental health conditions, including obesity and anxiety. As such disorders have early life antecedents, it is of value to determine if associations between the gut microbiome and behavior are present in early life in humans. Methods We used next generation pyrosequencing to examine associations between the community structure of the gut microbiome and maternal ratings of child temperament in 77 children at 18-27 months of age. It was hypothesized that children would differ in their gut microbial structure, as indicated by measures of alpha and beta diversity, based on their temperamental characteristics. Results Among both boys and girls, greater Surgency/Extraversion was associated greater phylogenetic diversity. In addition, among boys only, subscales loading on this composite scale were associated with differences in phylogenetic diversity, the Shannon Diversity index (SDI), beta diversity, and differences in abundances of Dialister, Rikenellaceae, Ruminococcaceae, and Parabacteroides. In girls only, higher Effortful Control was associated with a lower SDI score and differences in both beta diversity and Rikenellaceae were observed in relation to Fear. Some differences in dietary patterns were observed in relation to temperament, but these did not account for the observed differences in the microbiome. Conclusions Differences in gut microbiome composition, including alpha diversity, beta diversity, and abundances of specific bacterial species, were observed in association with temperament in toddlers. This study was cross-sectional and observational and, therefore, does not permit determination of the causal direction of effects. However, if bidirectional brain-gut relationships are present in humans in early life, this may represent an opportunity for intervention relevant to physical as well as mental health disorders.

The present study examined observations of parenting quality (mothers' emotional availability - EA) during infant bedtimes at 4 points across the infants' first year, assessing relations between levels and trajectories of emotional availability and infant attachment at 12 months and the role of infant temperament in moderating these associations. The sample (N = 128) was predominantly Euro-American (82.5%) and at low socioeconomic risk. Latent growth curve modeling with latent basis coefficients indicated substantial individual differences in initial levels and slopes in EA trajectories across the first year. Both levels of maternal EA and EA trajectories across the first year predicted 12-month infant attachment security. Although maternal EA tended to decrease across the first year in the full sample, EA trajectories that showed a “bounce-back” between 6 and 12 months, suggesting more successful maternal adaptation to an expanding infant developmental repertoire, predicted greater infant security at 12 months. In addition, linkages between latent EA trajectories and 12-month attachment were moderated by 3-month infant temperamental reactivity and regulation. These findings indicate that infant attachment security is sensitive to both static and dynamic aspects of parenting quality across the first year, and that infant temperament can interact with both in predicting infant attachment.

The prevalence of ADHD among patients with substance use disorder (SUD) is substantial. This study addressed the following research questions: Are early developmental, temperamental and educational problems overrepresented among SUD patients with ADHD compared to SUD patients without ADHD? Do this comorbid group receive early help for their ADHD, and are there signs of self-medicating with illicit central stimulants? An international, multi-centre cross-sectional study was carried out involving seven European countries, with 1205 patients in treatment for SUD. The mean age was 40 years and 27% of the sample was female. All participants were interviewed with the Mini International Neuropsychiatric Interview Plus and the Conners' Adult ADHD Diagnostic Interview for DSM-IV. SUD patients with ADHD ( n  = 196; 16.3% of the total sample) had a significantly slower infant development than SUD patients without ADHD ( n  = 1,009; 83.4%), had greater problems controlling their temperament, and had lower educational attainment. Only 24 (12%) of the current ADHD positive patients had been diagnosed and treated during childhood and/or adolescence. Finally, SUD patients with ADHD were more likely to have central stimulants or cannabis as their primary substance of abuse, whereas alcohol use was more likely to be the primary substance of abuse in SUD patients without ADHD. The results emphasize the importance of early identification of ADHD and targeted interventions in the health and school system, as well as in the addiction field.

Although behavioral inhibition (BI) is clearly identified as a temperamental risk factor for childhood anxiety psychopathology, much less is known about whether the strength of this association may vary as a function of parasympathetic nervous system regulation in children with anxiety disorders. To build upon extant research in this area, the present study examined whether respiratory sinus arrhythmia (RSA) can explicate the conditions in which BI is linked to increased symptom severity among anxiety-disordered children (N = 44; M = 9.61 years, SD = 1.63; 52% female and African American, respectively). We examined RSA responding both during a basal period and during a stressor ("challenge" RSA): interacting with a "mystery guest" who was wearing a mask. As hypothesized, the interaction between BI and both basal and challenge RSA was significantly related to anxiety disorder symptom severity, even after controlling for depressive symptoms. The form of the interaction indicated that highest levels of anxiety disorder symptoms were found among children with high levels of BI and low basal and challenge RSA, respectively. These data provide novel empirical evidence of a clinically-relevant interplay between RSA and BI in relation to anxiety disorder symptom severity among clinical youth. Future work is needed to expand on the specific mechanisms that may be responsible e for the interplay between temperamental and psychobiological risks for childhood anxiety.

Maternal depression represents an important social/environmental factor in early childhood; however, its effect on children's motor development may vary depending on the role of infants' dispositional variables. The objective of this study is to investigate the effect of the interaction between maternal depressive symptoms in the first two years of a child's life and the child's temperamental negative emotionality on motor development during this time. Using a cross-sectional study, we assessed 272 infants aged 0 to 24 months old and their mothers. We measured the following variables: maternal depression, infant's negative emotionality, and motor development. A three-way interaction effect highlights that negative emotionality in infants and maternal depression together affect children's overall motor growth trajectory. Infants with low negative emotionality display no effect of maternal depression on motor development. Conversely, infants with high negative emotionality seem to be more susceptible to the effect of maternal depression. Specifically, high maternal depression tends to foster the negative effect of infant's negativity on motor development across time, albeit not significantly. Finally, the absence of maternal depression significantly buffers negative temperament in infants. Findings highlighted the importance of integrating different perspectives when describing early motor growth. In fact, only when considering the interdependence of potential predictors their effect on the motor growth significantly emerges. Screening for early temperamental vulnerability might help in tailoring interventions to prevent maternal depression from affecting infants' motor development. Copyright © 2018 Elsevier B.V.

Neural responses to reward in childhood: relations to early behavioral inhibition and social anxiety

Abstract Behavioral inhibition (BI) is an early temperamental profile characterized by negative reactivity to novelty, withdrawal from social situations, and increased risk for social anxiety. Previous research associated BI assessed in early childhood to striatal hypersensitivity in mid-to-late adolescence. The present study examined this association among 10 year-olds, characterized with BI at ages 24 and 36 months on measures of temperamental reactivity. Participants (n = 40) were studied at age 10 using a reward processing task during functional magnetic resonance imaging (fMRI). Child- and maternal-report of social anxiety symptoms was collected at ages 10 and 13. Findings indicate greater caudate activation and stronger striatal connectivity in high, compared to low, behaviorally inhibited children. Caudate activation related to social anxiety symptoms at both ages. These findings suggest that enhanced striatal responsivity reliably manifests among high behaviorally inhibited children as early as age 10. This may reflect hyper-sensitivity to reward or excessive motivation to avoid errors. PMID:27531387

Child Temperamental Flexibility Moderates the Relation between Positive Parenting and Adolescent Adjustment

2016-01-01

Temperamental flexibility and lower positive parenting are associated with internalizing and externalizing problems; however, youth varying in flexibility may be differentially affected by positive parenting in the prediction of symptoms. We examined whether children's flexibility moderated prospective relations between maternal and paternal positive parenting and youth internalizing and externalizing symptoms during adolescence. Participants (N =775, 71% male) and their caregivers completed measures when youth were 10-12 and 12-14 years old. Father positive parenting interacted with child flexibility to predict father-reported internalizing and externalizing problems. Consistent with the diathesis-stress model, children lower in flexibility experienced greater symptoms than children higher in flexibility in lower positive parenting contexts. Among children lower in flexibility, lower paternal positive parenting was associated with greater internalizing and externalizing symptoms compared to higher paternal positive parenting. However, among youth higher in flexibility, symptom levels were similar regardless of whether youth experienced lower or higher paternal positive parenting. PMID:26834305

Background Difficult temperament in infancy is a risk factor for forms of later internalizing and externalizing psychopathology, including depression and anxiety. A better understanding of the roots of difficult temperament requires assessment of its early development with a genetically informative design. The goal of this study was to estimate genetic and environmental contributions to individual differences in infant negative emotionality, their persistence over time and their influences on stability between 5 and 18 months of age. Method Participants were 244 monozygotic and 394 dizygotic twin pairs (49.7% male) recruited from birth. Mothers rated their twins for negative emotionality at 5 and 18 months. Longitudinal analysis of stability and innovation between the two time points was performed in Mplus. Results There were substantial and similar heritability (approximately 31%) and shared environmental (57.3%) contributions to negative emotionality at both 5 and 18 months. The trait’s interindividual stability across time was both genetically- and environmentally- mediated. Evidence of innovative effects (i.e., variance at 18 months independent from variance at 5 months) indicated that negative emotionality is developmentally dynamic and affected by persistent and new genetic and environmental factors at 18 months. Conclusions In the first two years of life, ongoing genetic and environmental influences support temperamental negative emotionality but new genetic and environmental factors also indicate dynamic change of those factors across time. A better understanding of the source and timing of factors on temperament in early development, and role of sex, could improve efforts to prevent related psychopathology. PMID:28448561

An Evolutionary Perspective on Family Studies: Differential Susceptibility to Environmental Influences.

PubMed

Hartman, Sarah; Belsky, Jay

2016-12-01

An evolutionary perspective of human development provides the basis for the differential-susceptibility hypothesis which stipulates that individuals should differ in their susceptibility to environmental influences, with some being more affected than others by both positive and negative developmental experiences and environmental exposures. This paper reviews evidence consistent with this claim while revealing that temperamental and genetic characteristics play a role in distinguishing more and less susceptible individuals. The differential-susceptibility framework under consideration is contrasted to the traditional diathesis-stress view that "vulnerability" traits predispose some to being disproportionately affected by (only) adverse experiences. We raise several issues stimulated by the literature that need to be clarified in further research. Lastly, we suggest that therapy may differ in its effects depending on an individual's susceptibility. © 2015 Family Process Institute.

A psychometric evaluation of the Temperament in Middle Childhood Questionnaire (TMCQ) in a Swedish sample.

PubMed

Nystrom, Beatrice; Bengtsson, Hans

2017-12-01

Personality is generally considered to be biologically founded in temperament, and temperamental qualities have proven to be relatively stable across childhood and into adulthood (Caspi, Roberts & Shiner, ). Temperament predicts important developmental outcomes such as academic performance (Muris, ), and social functioning (Eisenberg, Fabes, Guthrie & Reiser, ), and it has also been found to be strongly related to the etiology and maintenance of internalizing and externalizing psychopathology in children (Muris, Meesters & Blijlevens, ; Nigg, ). To allow for the possibility of making early interventions, identification of potential risk factors (such as temperamental dispositions) is of great importance (Rettew & McKee, ). As temperament is multidimensional and has many different manifestations, parents and teachers are valuable sources in providing information about children's temperament (Rothbart & Bates, ; Tackett, Slobodskaya, Mar et al., ), and caregiver questionnaires are frequently used in child personality research. However, such questionnaires are only useful if their reliability and validity have been established. The aim of the present study was to examine the psychometric properties of the Temperament in Middle Childhood Questionnaire (TMCQ; Simonds, Kieras, Rueda & Rothbart, ), which focuses specifically on the ages between 7 and 11 years. The TMCQ is the least validated of the Rothbart measures, and although reliability data have been presented, together with some validity data, for a computerized self-report version of the questionnaire (Simonds & Rothbart, ), information about the reliability and validity for the caregiver version is scant. In the present paper, we report such data for a Swedish sample. © 2017 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

Impulsivity in patients with panic disorder-agoraphobia: the role of cyclothymia.

PubMed

Del Carlo, Alessandra; Benvenuti, Marzia; Toni, Cristina; Dell'osso, Liliana; Perugi, Giulio

2013-10-01

The relationship between Panic Disorder (PD) and impulsivity is not well explored. The present investigation aims to compare impulsivity, measured by different rating tools, in PD patients vs. healthy controls and to explore the influence of co-morbid Cyclothymic Disorder (CD) on the relationship between PD and impulsivity. Sixty-four subjects with PD and 44 matched controls underwent a diagnostic and symptomatological evaluations by the Mini Neuropsychiatric Interview (M.I.N.I) Plus 5.0; the Bech-Rafaelsen Depression and Mania Scale (BRDMS), the State-Trait Anxiety Inventory (STAI), the Hypomania Check List (HCL-32) and the Clinical Global Impression (CGI); the Questionnaire for the Affective and Anxious Temperament Evaluation of Memphis, Pisa, Paris and San Diego-Modified (TEMPS-M), the Separation Anxiety Sensitivity Index (SASI), the Interpersonal Sensitivity Symptoms Inventory (ISSI). Finally, psychometric and neurocognitive evaluations of impulsivity was carried out using the Barratt Impulsiveness Scale (BIS-11) and the Immediate and Delayed Memory Task (IMT/DMT). Subjects with PD were more impulsive than the controls in all the explored measures, reporting higher scores in symptomatological and temperamental scales. The comparison between PD patients with (Cyclo+) and without (Cyclo-) comorbid CD and controls showed that Cyclo+ are the most impulsive subjects in all the investigated measures and are characterized by the greatest symptomatological impairment, the highest scores in temperamental scales, and the highest levels of interpersonal sensitivity and separation anxiety. In our patients with PD, without lifetime comorbidity with major mood episodes, trait and state impulsivity may be related to the presence of comorbid cyclothymic mood instability.

Selective mutism and temperament: the silence and behavioral inhibition to the unfamiliar.

PubMed

Gensthaler, Angelika; Khalaf, Sally; Ligges, Marc; Kaess, Michael; Freitag, Christine M; Schwenck, Christina

2016-10-01

Behavioral inhibition (BI) is a suspected precursor of selective mutism. However, investigations on early behavioral inhibition of children with selective mutism are lacking. Children aged 3-18 with lifetime selective mutism (n = 109), social phobia (n = 61), internalizing behavior (n = 46) and healthy controls (n = 118) were assessed using the parent-rated Retrospective Infant Behavioral Inhibition (RIBI) questionnaire. Analyses showed that children with lifetime selective mutism and social phobia were more inhibited as infants and toddlers than children of the internalizing and healthy control groups, who displayed similar low levels of behavioral inhibition. Moreover, behavioral inhibition was higher in infants with lifetime selective mutism than in participants with social phobia according to the Total BI score (p = 0.012) and the Shyness subscale (p < 0.001). Infant behavioral inhibition, particularly towards social stimuli, is a temperamental feature associated with a lifetime diagnosis of selective mutism. Results yield first evidence of the recently hypothesized temperamental origin of selective mutism. Children at risk should be screened for this debilitating child psychiatric condition.

Relations of emotion-related temperamental characteristics to attentional biases and social functioning.

PubMed

Nozadi, Sara S; Spinrad, Tracy L; Johnson, Scott P; Eisenberg, Nancy

2018-06-01

The current study examined whether an important temperamental characteristic, effortful control (EC), moderates the associations between dispositional anger and sadness, attention biases, and social functioning in a group of preschool-aged children (N = 77). Preschoolers' attentional biases toward angry and sad facial expressions were assessed using eye-tracking, and we obtained teachers' reports of children's temperament and social functioning. Associations of dispositional anger and sadness with time looking at relevant negative emotional stimuli were moderated by children's EC, but relations between time looking at emotional faces and indicators of social functioning, for the most part, were direct and not moderated by EC. In particular, time looking at angry faces (and low EC) predicted high levels of aggressive behaviors, whereas longer time looking at sad faces (and high EC) predicted higher social competence. Finally, latency to detect angry faces predicted aggressive behavior under conditions of average and low levels of EC. Findings are discussed in terms of the importance of differentiating between components of attention biases toward distinct negative emotions, and implications for attention training.

Low Family Income and Behavior Problems in Norwegian Preschoolers: Is Child Emotionality a Marker for Sensitivity of Influence?

PubMed

Bøe, Tormod; Hysing, Mari; Zachrisson, Henrik Daae

2016-04-01

Poor children have higher rates of mental health problems than more affluent peers, also in progressive welfare states such as Norway. Temperamental characteristics may render some children more sensitive to the adverse influence of poor economy. This study examined the direct associations between family income-to-needs and mental health and assessed moderation by early temperamental characteristics (i.e., emotionality). Using data from the Norwegian Mother and Child Cohort Study, associations between income-to-needs across children's first 3 years and internalizing and externalizing problems when children were 5 years old were examined. Differential sensitivity to family income-to-needs was assessed by investigating how emotionality, when children were one-and-a-half and 3 years old, moderated these associations. Significant main effects of income-to-needs and emotionality and a significant interaction effect between income-to-needs and emotionality were found for externalizing problems, but not for internalizing problems. Children in poor families with an emotionally reactive temperament had higher scores on externalizing problems when they were 5 compared with their less emotionally reactive peers.

Longitudinal stability of temperamental exuberance and social-emotional outcomes in early childhood

PubMed Central

Degnan, Kathryn A.; Hane, Amie Ashley; Henderson, Heather A.; Moas, Olga Lydia; Reeb-Sutherland, Bethany C.; Fox, Nathan A.

2014-01-01

The goals of the current study were to investigate the stability of temperamental exuberance across infancy and toddlerhood and to examine the associations between exuberance and social-emotional outcomes in early childhood. The sample consisted of 291 4-month-olds followed at 9, 24, and 36 months, and again at 5 years of age. Behavioral measures of exuberance were collected at 9, 24, and 36 months. At 36 months, frontal EEG asymmetry was assessed. At 5 years, maternal reports of temperament and behavior problems were collected, as well as observational measures of social behavior during an interaction with an unfamiliar peer in the laboratory. Latent profile analysis revealed a high, stable exuberance profile, which was associated with greater 5-year externalizing behavior and surgency, as well as disruptive behavior and social competence with unfamiliar peers. These associations were particularly true for children who displayed left frontal EEG asymmetry. Multiple factors supported an approach bias for exuberant temperament, but did not differentiate between adaptive and maladaptive social-emotional outcomes at 5 years of age. PMID:21114347

"Reactivity to Stimuli” Is a Temperamental Factor Contributing to Canine Aggression

PubMed Central

Arata, Sayaka; Takeuchi, Yukari; Inoue, Mai; Mori, Yuji

2014-01-01

Canine aggression is one of the most frequent problems in veterinary behavioral medicine, which in severe cases may result in relinquishment or euthanasia. As it is important to reveal underlying factors of aggression for both treatment and prevention, we recently developed a questionnaire on aggression and temperamental traits and found that “reactivity to stimuli” was associated with aggression toward owners, children, strangers, and other dogs of the Shiba Inu breed. In order to examine whether these associations were consistent in other breeds, we asked the owners of insured dogs of Anicom Insurance Inc. to complete our questionnaire. The top 17 contracted breeds were included. The questionnaire consisted of dogs' general information, four items related to aggression toward owners, children, strangers, and other dogs, and 20 other behavioral items. Aggression-related and behavioral items were rated on a five-point frequency scale. Valid responses (n = 5610) from owners of dogs aged 1 through 10 years were collected. Factor analyses on 18 behavioral items (response rate over 95%) extracted five largely consistent factors in 14 breeds: “sociability with humans,” “fear of sounds,” “chase proneness,” “reactivity to stimuli,” and “avoidance of aversive events.” By stepwise multiple regression analyses, using the Schwartz's Bayesian information criterion (BIC) method with aggression points as objective variables and general information and temperamental factor points as explanatory variables, “reactivity to stimuli,” i.e., physical reactivity to sudden movement or sound at home, was shown to be significantly associated with owner-directed aggression in 13 breeds, child-directed aggression in eight breeds, stranger-directed aggression in nine breeds, and dog-directed aggression in five breeds. These results suggest that “reactivity to stimuli” is simultaneously involved in several types of aggression. Therefore, it would be worth taking “reactivity to stimuli” into account in the treatment and prevention of canine aggression. PMID:24972077

Impulsivity is a core personality trait forming part of normal behavior and contributing to adaptive functioning. However, in typically developing children, altered patterns of impulsivity constitute a risk factor for the development of behavioral problems. Since both pathological and non-pathological states are commonly characterized by continuous transitions, we used a correlative approach to investigate the potential link between personality and brain dynamics. We related brain functional connectivity of typically developing children, measured with magnetic resonance imaging at rest, with their impulsivity scores obtained from a questionnaire completed by their parents. We first looked for areas within the default mode network (DMN) whose functional connectivity might be modulated by trait impulsivity. Then, we calculated the functional connectivity among these regions and the rest of the brain in order to assess if impulsivity trait altered their relationships. We found two DMN clusters located at the posterior cingulate cortex and the right angular gyrus which were negatively correlated with impulsivity scores. The whole-brain correlation analysis revealed the classic network of correlating and anti-correlating areas with respect to the DMN. The impulsivity trait modulated such pattern showing that the canonical anti-phasic relation between DMN and action-related network was reduced in high impulsive children. These results represent the first evidence that the impulsivity, measured as personality trait assessed through parents' report, exerts a modulatory influence over the functional connectivity of resting state brain networks in typically developing children. The present study goes further to connect developmental approaches, mainly based on data collected through the use of questionnaires, and behavioral neuroscience, interested in how differences in brain structure and functions reflect in differences in behavior.

ANIMAL BEHAVIOR AND WELL-BEING SYMPOSIUM: Interaction between coping style/personality, stress, and welfare: Relevance for domestic farm animals.

PubMed

Koolhaas, J M; Van Reenen, C G

2016-06-01

This paper will argue that understanding animal welfare and the individual vulnerability to stress-related disease requires a fundamental understanding of functional individual variation as it occurs in nature as well as the underlying neurobiology and neuroendocrinology. Ecological studies in feral populations of mice, fish, and birds start to recognize the functional significance of phenotypes that individually differ in their behavioral and neuroendocrine response to environmental challenge. Recent studies indicate that the individual variation within a species may buffer the species for strong fluctuations in the natural habitat. Similarly, evolutionary ancient behavioral trait characteristics have now been identified in a range of domestic farm animals including cattle, pigs, and horses. Individual variation in behavior can be summarized in a 3-dimensional model with coping style, emotionality, and sociality as independent dimensions. These dimensions can be considered trait characteristics that are stable over time and across situations within the individual. This conceptual model has several consequences. First, the coping style dimension is strongly associated with differential stress vulnerability. Social stress studies show that proactive individuals are resilient under stable environmental conditions but vulnerable when outcome expectancies are violated. Reactive individuals are, in fact, rather flexible and seem to adapt more easily to a changing environment. A second consequence relates to genetics and breeding. Genetic selection for one trait usually implies selection for other traits as well. It is discussed that a more balanced breeding program that takes into account biologically functional temperamental traits will lead to more robust domestic farm animals. Finally, the relationship between temperamental traits, animal production, fitness, and welfare is discussed.

TEMPERAMENTAL ADAPTABILITY, PERSISTENCE, AND REGULARITY: PARENTAL RATINGS OF NORWEGIAN INFANTS AGED 6 TO 12 MONTHS, WITH SOME IMPLICATIONS FOR PREVENTIVE PRACTICE.

There is a need for standardized measures of infant temperament to strengthen current practices in prevention and early intervention. The present study provides Norwegian data on the Cameron-Rice Infant Temperament Questionnaire (CRITQ; J.R. Cameron & D.C. Rice, 1986a), which comprises 46 items and is used within a U.S. health maintenance organization. The CRITQ was filled out by mothers and fathers at 6 and again at 12 months as part of a longitudinal study of mental health during the first years of life (the "Little in Norway" study, N = 1,041 families enrolled; V. Moe & L. Smith, 2010). Results showed that internal consistencies were comparable with U.S. The temperament dimensions of persistence, adaptability, and regularity had acceptable or close-to-acceptable reliabilities in the U.S. study as well as in this study, and also were unifactorial in confirmatory factor analysis. These dimensions are the focus in this article. Findings concerning parents' differential ratings of their infants on the three dimensions are reported, as is the stability of parents' ratings of temperament from 6 to 12 months. In addition, results on the relation between temperament and parenting stress are presented. The study suggests that temperamental adaptability, persistence, and regularity may be relevant when assessing infant behavior, and may be applied in systematic prevention trials for families with infants. The inclusion of concepts related to individual differences in response tendencies and regulatory efforts may broaden the understanding of parent-infant transactions, and thus enrich prevention and sensitizing interventions with the aim of assisting infants' development. © 2018 Michigan Association for Infant Mental Health.

2016-07-01

The purpose of this study was to determine the cumulative rates of 2- and 4-year remission, and the recurrences that follow them, of 24 symptoms of borderline personality disorder over 16 years of prospective follow-up. A total of 290 inpatients meeting rigorous criteria for borderline personality disorder and 72 axis II comparison subjects were assessed during their index admission using a series of semistructured diagnostic interviews. The same instruments were readministered at eight contiguous 2-year time periods. The 12 acute symptoms (e.g., self-mutilation, help-seeking suicide attempts) of borderline personality disorder were more likely to remit for a period of 2 years and for a period of 4 years than the 12 temperamental symptoms (e.g., chronic anger/frequent angry acts, intolerance of aloneness) of this disorder. They were also less likely to recur after a remission lasting 2 years or a remission lasting 4 years. Taken together, the symptoms of borderline personality disorder are quite fluid, with remissions and recurrences being common. However, the more clinically urgent acute symptoms of borderline personality disorder seem to have a better prognosis than the less turbulent temperamental symptoms of the disorder.

Adolescents ages 10–15 experience dramatic changes in their biological, cognitive, emotional, and social development as well as in their physical and social environments. These include the physiological and psychological changes associated with puberty; further development of the brain; changes in family, peer, and romantic relationships; and exposure to new societal and cultural influences. During this period, many adolescents also begin to use alcohol. Alcohol use during adolescence has adverse effects on the body and increases the risk of alcohol dependence later in life. To better understand why some children drink whereas others do not, researchers are examining nonspecific and alcohol-specific factors that put adolescents at risk for, or which protect them from, early alcohol use and its associated problems. Nonspecific risk factors include certain temperamental and personality traits, family factors, and nonnormative development. Examples of nonspecific protective factors include certain temperamental characteristics, religiosity, and parenting factors (e.g., parental nurturance and monitoring). Among the most influential alcohol-specific risk and protective factors are a family history of alcoholism and the influences of siblings and peers, all of which shape an adolescent’s expectancies about the effects of alcohol, which in turn help determine alcohol use behaviors.

Planalp, Elizabeth M; Braungart-Rieker, Julia M

2015-03-01

The ability to effectively regulate emotions is an important marker for early socioemotional development. The uses of self-comforting behaviors and self-distraction have been empirically supported as effective regulatory strategies for infants, though research on determinants of such behaviors is scarce. Thus, a more thorough examination of the development of regulatory behaviors is needed. For the current study, 135 mothers, fathers, and their infants participated in laboratory visits at 3-, 5-, and 7-months of age where parent sensitivity and infant regulatory strategies were coded from the Still Face Paradigm. Parents also filled out questionnaires about infant temperament and parental involvement. Using multi-level modeling to examine levels and trajectories of self-comforting and self-distraction, the current study found: 1) infants higher in temperamental surgency used more self-distraction and self-comforting, 2) infants lower in surgency with highly involved parents increased in self-distraction at a faster rate, particularly with highly involved fathers, and 3) infants used self-comforting more than average with fathers when the infant was also lower in temperamental regulation. In addition, we examined trajectories of parent involvement and temperament in relation to infant regulatory strategy.

Is Positive Emotionality a Specific Risk Factor for Depression? A Meta-Analysis of Longitudinal Studies

PubMed Central

Khazanov, Gabriela Kattan; Ruscio, Ayelet Meron

2016-01-01

Depression is well known to share a negative cross-sectional relationship with personality constructs defined by positive emotion (positive affect, extraversion, behavioral activation). These Positive Emotionality (PE) constructs have been proposed to represent stable temperamental risk factors for depression, not merely current mood state. These constructs have also been proposed to increase risk specifically for depression, relative to anxiety. We performed a meta-analysis of longitudinal studies to examine the relationship of PE to depression (59 effect sizes) and anxiety (26 effect sizes). In cross-sectional analyses, PE constructs were negatively associated with depression (r = −.34) and anxiety (r = −.24). PE constructs also prospectively predicted depression (r = −.26) and anxiety (r = −.19). These relationships remained statistically significant, but were markedly attenuated, when baseline levels of depression (β = −.08) and anxiety (β = −.06) were controlled. Moreover, depression and anxiety were equally strong predictors of subsequent changes in PE (β = −.07 and −.09, respectively). These findings are consistent with theoretical accounts of low PE as a temperamental vulnerability for depression, but suggest that the prospective relationship of PE to depression may be weaker and less specific than previously assumed.

2016-01-01

Background Poor children have higher rates of mental health problems compared to more affluent peers, also in progressive welfare states like Norway. Temperamental characteristics may render some children more sensitive to the adverse influence of poor economy. Objective The current study examined the direct associations between family income-to-needs and mental health, and assessed moderation by early temperamental characteristics (i.e., emotionality). Method Using data from the Norwegian Mother and Child Cohort Study, associations between income-to-needs across children's first three years, and internalizing and externalizing problems when children were five years old were examined. Differential sensitivity to family income-to-needs was assessed by investigating how emotionality, when children were one-and-a-half and three years old, moderated these associations. Results Significant main effects of income-to-needs and emotionality, and a significant interaction effect between income-to-needs and emotionality was found for externalizing problems, but not for internalizing problems. Conclusion Children in poor families with an emotionally reactive temperament had higher scores on externalizing problems when they were five compared to their less emotionally reactive peers.

SI-SHY: Dysregulated Fear in Toddlerhood Predicts Kindergarten Social Withdrawal through Protective Parenting.

PubMed

Kiel, Elizabeth J; Buss, Kristin A

2014-05-01

Two recent advances in the study of fearful temperament (behavioral inhibition) include the validation of dysregulated fear as a temperamental construct that more specifically predicts later social withdrawal and anxiety, and the use of conceptual and statistical models that place parenting as a mechanism of development from temperament to these outcomes. The current study further advances these areas by examining whether protective parenting mediated the relation between dysregulated fear in toddlerhood and social withdrawal in kindergarten. Participants included 93 toddlers and their mothers, who engaged in laboratory tasks assessing traditional fearful temperament, dysregulated fear, and protective parenting. When children reached kindergarten, they returned to the laboratory for a multimethod assessment of social withdrawal. Results confirmed the hypothesis that dysregulated fear predicted social withdrawal through protective parenting, and this occurred above and beyond the effect of traditional fearful temperament. These findings bolster support for the use of dysregulated fear as a temperamental construct related to, but perhaps more discerning of risk than traditionally measured fearful temperament/behavioral inhibition and highlight the importance of transactional influences between the individual and the caregiving environment in the development of social withdrawal.

Linking Temperamental Shyness and Social Anxiety in Childhood and Adolescence: Moderating Influences of Sex and Age.

Tsui, Tiffany Y L; Lahat, Ayelet; Schmidt, Louis A

2017-10-01

Although childhood shyness has been linked to social anxiety problems, the factors playing a role in this association have gone largely unexplored. Here we examined the potential moderating roles of sex and age on this relation in a sample of 119 (75 girls) children (10-12 years) and adolescents (14-16 years). As predicted, shyness was positively associated with social anxiety symptoms. Sex, but not age, served as a moderating factor in linking shyness and social anxiety. Specifically, shyness was more strongly associated with social anxiety symptoms among girls than boys. These results suggest the importance of considering sex differences when examining the relation between shyness and social anxiety in childhood and adolescence.

Temperament and personality in eating disorders.

PubMed

Rotella, Francesco; Fioravanti, Giulia; Ricca, Valdo

2016-01-01

In the last decades, three main different personality domains have been investigated in the field of eating disorders: personality traits, temperament, and personality disorders. The use of a wide range of instruments and the presence of many different approaches in the definition of personality dimensions make it difficult to summarize the emerging results from different studies. The aim of this narrative review is to critically highlight and discuss all interesting developments in this field, as reflected in the recent literature. The study of personality and temperament in eating disorders seems to be in line with the recently suggested dimensional approach, which highlights the importance of symptoms aggregation, rather than the categorical diagnoses. Recent literature seems to confirm that specific personality and temperamental profiles can be drawn for patients with eating disorders, which can discriminate different eating disorders' diagnoses/symptoms. These observations have relevant clinical implications as treatment of eating disorders is largely based on psychotherapeutic interventions. However, large longitudinal studies are needed to better clarify the suggested relationships and to identify more defined therapeutic strategies.

A phenotype of early infancy predicts reactivity of the amygdala in male adults.

Schwartz, C E; Kunwar, P S; Greve, D N; Kagan, J; Snidman, N C; Bloch, R B

2012-10-01

One of the central questions that has occupied those disciplines concerned with human development is the nature of continuities and discontinuities from birth to maturity. The amygdala has a central role in the processing of novelty and emotion in the brain. Although there is considerable variability among individuals in the reactivity of the amygdala to novel and emotional stimuli, the origin of these individual differences is not well understood. Four-month old infants called high reactive (HR) demonstrate a distinctive pattern of vigorous motor activity and crying to specific unfamiliar visual, auditory and olfactory stimuli in the laboratory. Low-reactive infants show the complementary pattern. Here, we demonstrate that the HR infant phenotype predicts greater amygdalar reactivity to novel faces almost two decades later in adults. A prediction of individual differences in brain function at maturity can be made on the basis of a single behavioral assessment made in the laboratory at 4 months of age. This is the earliest known human behavioral phenotype that predicts individual differences in patterns of neural activity at maturity. These temperamental differences rooted in infancy may be relevant to understanding individual differences in vulnerability and resilience to clinical psychiatric disorder. Males who were HR infants showed particularly high levels of reactivity to novel faces in the amygdala that distinguished them as adults from all other sex/temperament subgroups, suggesting that their amygdala is particularly prone to engagement by unfamiliar faces. These findings underline the importance of taking gender into account when studying the developmental neurobiology of human temperament and anxiety disorders. The genetic study of behavioral and biologic intermediate phenotypes (or 'endophenotypes') indexing anxiety-proneness offers an important alternative to examining phenotypes based on clinically defined disorder. As the HR phenotype is characterized by specific patterns of reactivity to elemental visual, olfactory and auditory stimuli, well before complex social behaviors such as shyness or fearful interaction with strangers can be observed, it may be closer to underlying neurobiological mechanisms than behavioral profiles observed later in life. This possibility, together with the fact that environmental factors have less time to impact the 4-month phenotype, suggests that this temperamental profile may be a fruitful target for high-risk genetic studies.

Roles of temperamental arousal and gender-segregated play in young children's social adjustment.

PubMed

Fabes, R A; Shepard, S A; Guthrie, I K; Martin, C L

1997-07-01

The hypothesis that gender differences in children's adjustment is partially influenced by differences in temperament and interactions with same-sex peers was examined. Fifty-seven predominantly White, middle-class preschoolers (29 boys and 28 girls, M age = 54.5 months) participated. Measures were taken of children's arousability, problem behaviors, and tendencies to play with same-sex peers. A semester later, children's peer status was assessed. Analyses revealed that arousability and same-sex peer play interacted to predict problem behaviors. For boys high in arousability, play with same-sex peers increased problem behaviors. In contrast, arousable girls who played with other girls were relatively unlikely to show problem behaviors. Moreover, the interaction of arousability and same-sex peer play predicted boys' (but not girls') peer status, and this relation was partially mediated by problem behaviors. The role of gender-related processes is discussed.

Reaction to background stimulation of preschool children who do and do not stutter.

Schwenk, Krista A; Conture, Edward G; Walden, Tedra A

2007-01-01

This study investigated the maintenance of attention and adaptation to background stimuli of preschool children who do (CWS) and do not stutter (CWNS). Participants were 13 monolingual, Standard American English speaking, 3-5-year-old CWS and 14 CWNS. Results indicated that CWS were significantly more apt than CWNS to attend to or look at changes in background stimuli, although there were no significant differences between groups in duration and latency of these looks. Findings suggest that preschool CWS are more reactive to, distracted by, and slower to adapt and habituate to environmental stimuli than their CWNS counterparts. The reader should be able to: (1) recognize the temperamental differences between CWS and CWNS, (2) define attention reactivity and regulation, (3) explain how attention reactivity and regulation are associated with preschool stuttering, and (4) understand recent empirical evidence relating reactivity and regulation to preschool stuttering.

The experience of shame is an adaptive and natural reaction until it becomes a chronic and painful emotion as a result of environment and temperamental factors. According to studies of the last decade chronic shame is a central feature of the social interactions as well as of a variety of psychopathologies including anxiety disorders, depression, eating disorders, and personality disorders. This study presents an overview of the definition and the major theories of shame describing developmental factors of shame and ways to coping with it. The research results concerning the relationship between shame and different disorders will be summarized in a following study.

Temperamental Stability as a Function of Change in Birth Order Status.

Relations of maternal and child characteristics to child cortisol reactivity to and recovery from emotional arousal were examined prospectively at approximately 7 months of age (infancy) and then again at approximately 15 months of age (toddlerhood). The sample was diverse and population based (N = 1,292 mother-infant dyads) and included families from predominantly low-income, rural communities. Maternal behavior, family income-to-need ratio and social advantage, and child temperament, attention, and mental development were assessed, and children's saliva was sampled before and after standardized procedures designed to elicit emotional arousal. Maternal engagement in infancy was associated with greater cortisol reactivity at the infancy assessment and with reduced overall cortisol level at the toddler assessment. Also at the toddler assessment, child attention, mental development, and temperamental distress to novelty were associated with increased cortisol reactivity and regulation, whereas temperamental distress to limitations and African American ethnicity were associated with reduced cortisol reactivity. Findings are consistent with prior work linking early caregiving to the development of the hypothalamic-pituitary-adrenal axis stress response system and with a conceptual model in which developing temperament is characterized by the interplay of emotional reactivity and the emergence of the ability to effortfully regulate this reactivity using attention.

Previous research has shown that two dimensions of temperament referred to as neuroticism/behavioral inhibition (N/BI) and extraversion/behavioral activation (E/BA) are key risk factors in the development and maintenance of anxiety and mood disorders (Brown & Barlow, 2009). Given such findings, these temperamental dimensions may represent promising treatment targets for individuals with emotional disorders; however, to date, few studies have investigated the effects of psychological treatments on temperamental constructs generally assumed to be "stable, inflexible, and pervasive" (American Psychiatric Association, 2000). The present study addresses this gap in the literature by examining the effects of the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP; Barlow et al., 2011), a cognitive-behavioral therapy designed to target core processes of N/BI and E/BA temperaments, in a sample of adults with principal anxiety disorders and a range of comorbid conditions. Results revealed small effects of the UP on N/BI and E/BA compared with a waitlist control group at post-treatment. Additionally, decreases in N/BI and increases in E/BA during treatment were associated with improvements in symptoms, functioning, and quality of life. Findings provide preliminary support for the notion that the UP treatment facilitates beneficial changes in dimensions of temperament. Copyright © 2014 Elsevier Inc. All rights reserved.

Abstract Childhood family adversity (CFA) increases the risk for conduct disorder (CD) and has been associated with alterations in regions of affective processing like ventral striatum (VS) and amygdala. However, no study so far has demonstrated neural converging effects of CFA and CD in the same sample. At age 25 years, functional MRI data during two affective tasks, i.e. a reward (N = 171) and a face-matching paradigm (N = 181) and anatomical scans (N = 181) were acquired in right-handed currently healthy participants of an epidemiological study followed since birth. CFA during childhood was determined using a standardized parent interview. Disruptive behaviors and CD diagnoses during childhood and adolescence were obtained by diagnostic interview (2–19 years), temperamental reward dependence was assessed by questionnaire (15 and 19 years). CFA predicted increased CD and amygdala volume. Both exposure to CFA and CD were associated with a decreased VS response during reward anticipation and blunted amygdala activity during face-matching. CD mediated the effect of CFA on brain activity. Temperamental reward dependence was negatively correlated with CFA and CD and positively with VS activity. These findings underline the detrimental effects of CFA on the offspring's affective processing and support the importance of early postnatal intervention programs aiming to reduce childhood adversity factors.

Early temperamental sensitivity may form the basis for the later development of socioemotional maladjustment. In particular, temperamental negative affect places children at risk for the development of anxiety. However, not all children who show negative affect go on to develop anxiety or extreme social withdrawal. Recent research indicates that reactive control, in the form of attention to threat, may serve as a bridge between early temperament and the development of later social difficulties. In addition, variation in effortful control may also modulate this trajectory. Children (MeanAge=5.57 years) were assessed for attention bias to threatening and pleasant faces using a dot-probe paradigm. Attention bias to threatening (but not happy) faces moderated the direct positive relation between negative affect and social withdrawal. Children with threat biases showed a significant link between negative affect and social withdrawal, while children who avoided threat did not. In contrast, effortful control did not moderate the relation between negative affect and social withdrawal. Rather, there was a direct negative relation between effortful control and social withdrawal. The findings from this short report indicate that the relation amongst temperament, attention bias, and social withdrawal appears early in life and point to early emerging specificity in reactive and regulatory functioning.

The Cool Little Kids randomised controlled trial: Population-level early prevention for anxiety disorders

PubMed Central

2011-01-01

Background The World Health Organization predicts that by 2030 internalising problems (e.g. depression and anxiety) will be second only to HIV/AIDS in international burden of disease. Internalising problems affect 1 in 7 school aged children, impacting on peer relations, school engagement, and later mental health, relationships and employment. The development of early childhood prevention for internalising problems is in its infancy. The current study follows two successful 'efficacy' trials of a parenting group intervention to reduce internalising disorders in temperamentally inhibited preschool children. Cool Little Kids is a population-level randomised trial to determine the impacts of systematically screening preschoolers for inhibition then offering a parenting group intervention, on child internalising problems and economic costs at school entry. Methods/Design This randomised trial will be conducted within the preschool service system, attended by more than 95% of Australian children in the year before starting school. In early 2011, preschool services in four local government areas in Melbourne, Australia, will distribute the screening tool. The ≈16% (n≈500) with temperamental inhibition will enter the trial. Intervention parents will be offered Cool Little Kids, a 6-session group program in the local community, focusing on ways to develop their child's bravery skills by reducing overprotective parenting interactions. Outcomes one and two years post-baseline will comprise child internalising diagnoses and symptoms, parenting interactions, and parent wellbeing. An economic evaluation (cost-consequences framework) will compare incremental differences in costs of the intervention versus control children to incremental differences in outcomes, from a societal perspective. Analyses will use the intention-to-treat principle, using logistic and linear regression models (binary and continuous outcomes respectively) to compare outcomes between the trial arms. Discussion This trial addresses gaps for internalising problems identified in the 2004 World Health Organization Prevention of Mental Disorders report. If effective and cost-effective, the intervention could readily be applied at a population level. Governments consider mental health to be a priority, enhancing the likelihood that an effective early prevention program would be adopted in Australia and internationally.

Stuttering in relation to anxiety, temperament, and personality: review and analysis with focus on causality.

PubMed

Alm, Per A

2014-06-01

Anxiety and emotional reactions have a central role in many theories of stuttering, for example that persons who stutter would tend to have an emotionally sensitive temperament. The possible relation between stuttering and certain traits of temperament or personality were reviewed and analyzed, with focus on temporal relations (i.e., what comes first). It was consistently found that preschool children who stutter (as a group) do not show any tendencies toward elevated temperamental traits of shyness or social anxiety compared with children who do not stutter. Significant group differences were, however, repeatedly reported for traits associated with inattention and hyperactivity/impulsivity, which is likely to reflect a subgroup of children who stutter. Available data is not consistent with the proposal that the risk for persistent stuttering is increased by an emotionally reactive temperament in children who stutter. Speech-related social anxiety develops in many cases of stuttering, before adulthood. Reduction of social anxiety in adults who stutter does not in itself appear to result in significant improvement of speech fluency. Studies have not revealed any relation between the severity of the motor symptoms of stuttering and temperamental traits. It is proposed that situational variability of stuttering, related to social complexity, is an effect of interference from social cognition and not directly from the emotions of social anxiety. In summary, the studies in this review provide strong evidence that persons who stutter are not characterized by constitutional traits of anxiety or similar constructs. This paper provides a review and analysis of studies of anxiety, temperament, and personality, organized with the objective to clarify cause and effect relations. Readers will be able to (a) understand the importance of effect size and distribution of data for interpretation of group differences; (b) understand the role of temporal relations for interpretation of cause and effect; (c) discuss the results of studies of anxiety, temperament and personality in relation to stuttering; and (d) discuss situational variations of stuttering and the possible role of social cognition.

Objective To examine whether individual differences and intraindividual (within-person day-to-day) fluctuations in late adolescents’ self-regulation were associated with daily adherence to the type 1 diabetes regimen. Methods 110 school seniors (M age = 17.78 years) and their mothers assessed adolescents’ skills underlying self-regulation (executive function, attention, self-control, behavioral inhibition and activation, emotion regulation) and adherence, with glycosylated hemoglobin from medical records. Teens completed daily diaries reporting self-regulation failures surrounding monitoring blood glucose, adherence, and number of blood glucose checks each day for 14 days. Results Hierarchical Linear Models indicated that better daily adherence was associated with teen and mother reports of better self-regulation skills and teens’ reports of fewer daily self-regulation failures. Daily adherence was unrelated to temperamental differences in behavioral inhibition and activation. Conclusions Results indicate that both individual and intraindividual differences in self-regulation contribute to daily adherence highlighting the importance of daily self-regulatory challenges to adherence.

Novelty seeking (NS) and harm avoidance (HA) are two major dimensions of temperament in Cloninger׳s neurobiological model of personality. Previous neurofunctional and biological studies on temperament dimensions of HA and NS suggested that the temperamental traits have significant correlations with cortical and subcortical brain regions. However, no study to date has investigated the functional network modular organization as a function of the temperament dimension. The temperament dimensions were originally proposed to be independent of one another. However, a meta-analysis based on 16 published articles found a significant negative correlation between HA and NS (Miettunen et al., 2008). Based on this negative correlation, the current study revealed the whole-brain connectivity modular architecture for two contrasting temperament groups. The k-means clustering algorithm, with the temperamental traits of HA and NS as an input, was applied to divide the 40 subjects into two temperament groups: 'high HA and low NS' versus 'low HA and high NS'. Using the graph theoretical framework, we found a functional segregation of whole brain network architectures derived from resting-state functional MRI. In the 'high HA and low NS' group, the regulatory brain regions, such as the prefrontal cortex (PFC), are clustered together with the limbic system. In the 'low HA and high NS' group, however, brain regions lying on the dopaminergic pathways, such as the PFC and basal ganglia, are partitioned together. These findings suggest that the neural basis of inhibited, passive, and inactive behaviors in the 'high HA and low NS' group was derived from the increased network associations between the PFC and limbic clusters. In addition, supporting evidence of topological differences between the two temperament groups was found by analyzing the functional connectivity density and gray matter volume, and by computing the relationships between the morphometry and function of the brain.

The current study examined the relationships between academic achievement, sleep, temperament and demographic-historical data in school-age children. Teachers were asked to fill out the teacher temperament questionnaire and a form for school achievement, while mothers filled out a demographic-historical form and the sleep disturbance scale for children (SDSC), a 26-item questionnaire that consisted of six factors: difficulty in initiating and maintaining sleep (DIMS), sleep breathing disorders (SBD), arousal disorders (DA), sleep-wake transition disorders (SWTD), disorders of excessive somnolence (DOES), sleep hyperhydrosis (SHY). From a sample of 380 school children, 264 (70%) were suitable for the analyses (141 M and 123 F aged 8-11 years, mean 9.6 years). A school achievement index (SAI) was derived, summing up four items (reading ability, reading comprehension, mathematics, executive ability) of the teacher form for school achievement. SAI mean for the total sample was 11.1 (SD=2.8). A significant gender difference was found: females have higher SAI than males. The analysis of the demographic-historical form showed that only two factors appeared to affect SAI score: enuresis and the low educational level of the mother. The pattern of correlations showed that (a) the SAI was negatively related to the SDSC total score, in particular to DIMS and DOES sub-factors, and (b) the SAI was significantly and positively correlated with the temperamental traits of task-orientation and personal-social flexibility. A multiple stepwise regression analysis showed that the temperamental traits task-orientation and personal-social flexibility are the most predictive factors for SAI while the mother's educational level and the SDSC total score, although they contributed significantly to the prediction of SAI, accounted for only a small portion of variance. Temperament and sleep are important factors influencing school achievement, and their assessment could help to identify children at risk regarding school achievement.

Monitoring, metacognition, and executive function: elucidating the role of self-reflection in the development of self-regulation.

While an abundance of research has investigated the development of the automatic and controlled processes through which individuals control their thoughts, emotions, and actions, less research has emphasized the role of the self in self-regulation. This chapter synthesizes four literatures that have examined the mechanisms through which the individual acts in a managerial role, evaluating the current status of the system and initiating regulatory actions as necessary. Taken together, these literatures (on executive function, error monitoring, metacognition, and uncertainty monitoring) suggest that self-reflection plays a critical role in self-regulation, and that developmental improvements in self-reflection (via increasing levels of conscious awareness and enhanced calibration of monitoring systems) may serve as driving forces underlying developmental improvement (and temperamental individual differences) in children's ability to control their thoughts and actions.

Infant sleep consolidates rapidly during the first half year of life in the context of a dynamic, bidirectional exchange between infant characteristics and the caregiving environment. The current study examined relations among mothers’ emotional availability (EA) at bedtime, infant temperament, and objectively assessed infant sleep development from 1 to 6 months, and in particular focused on whether infant temperament moderated linkages between EA at bedtime and infant sleep development. The sample consisted of seventy-two mother-infant dyads, and measures included actigraphy-assessed infant sleep at 1 and 6 months, observed maternal EA coded from bedtime videos at 3 and 6 months, and maternal reports of infant temperament at 3 and 6 months. Analysis showed significant positive effects of maternal EA at bedtime on developmental changes in infant sleep minutes. Additionally, infant temperamental surgency moderated the influence of EA at bedtime on the increase in infant sleep minutes. In other words, highly surgent infants increased their sleep time more than other infants if their mothers were emotionally available at bedtime. Results were discussed in terms of the transactional model of infant sleep development. PMID:27692276

Background: Personal and environmental factors might have an impact on strategies of coping with stress and temperamental traits according to the Regulative Theory of Temperament in asthmatic patients. They can modify the clinical picture, the course of a disease and effectiveness of treatment. Personal variables are key factors in determining formal characteristic of behavior and effective management method in asthmatic patients. Aim of study: The aim of the study was to identify selected personal and environmental factors, as well as factors inducing attacks and asthma exacerbations or maintaining them in a complex of personal traits of patients. Methods: Two hundred and eighty one participants were included in the study. Of this number 122 subjects were healthy volunteers and 159 were asthmatic patients. In all the subjects the authors applied the Formal Characteristic of Behaviour – FCZ-KT – Temperament Inventory, Coping Inventory for Stressful Situations (CISS), Beck Depression Inventory, State-Trait Anxiety Inventory and Borg Rating of Perceived Exertion (RPE) Scale. Genotyping of polymorphic forms of NR3C1 gene was conducted with PCR-RFLP and PCR-HRM methods. Expression of TGFβ1 gene was measured with the use of qRT-PCR. Results: The authors confirmed a significant influence of personal and environmental factors, such as: age, height, body weight, sex, asthma exacerbations, drugs administered by patients, allergy and psychopathological variables on strategies of coping with stress by asthmatic patients (Task-Oriented Coping, Emotion-Oriented Coping, Avoidance-Oriented Coping, distraction seeking, social diversion). Temperamental traits (Briskness, Perseverance, Sensory Sensitivity, Emotional Reactivity, Endurance, Activity) depend on age, sex, body weight, genetic predispositions and they are modified by asthma exacerbations, allergy, drugs administered by patients, depression and anxiety (state and trait). The authors confirmed a correlation between Tth111I polymorphic form of NR3C1 gene and perseverance (p= 0.0450). It was noted that an increase in the TGFβ1 expression level led to a decrease in the patients' emotional reactivity (p= 0.0212). Conclusions: Strategies of coping with stress and temperamental traits according to the Regulative Theory of Temperament in asthmatic patients are determined by personal and environmental factors.

Recent data, including our own, indicate significant overlap between atypical depression and bipolar II. Furthermore, the affective fluctuations of patients with these disorders are difficult to separate, on clinical grounds, from cyclothymic temperamental and borderline personality disorders. The present analyses are part of an ongoing Pisa-San Diego investigation to examine whether interpersonal sensitivity, mood reactivity and cyclothymic mood swings constitute a common diathesis underlying the atypical depression-bipolar II-borderline personality constructs. We examined in a semi-structured format 107 consecutive patients who met criteria for major depressive episode with DSM-IV atypical features. Patients were further evaluated on the basis of the Atypical Depression Diagnostic Scale (ADDS), the Hopkins Symptoms Check-list (HSCL-90), and the Hamilton Rating Scale for Depression (HRSD), coupled with its modified form for reverse vegetative features as well as Axis I and SCID-II evaluated Axis II comorbidity, and cyclothymic dispositions ('APA Review', American Psychiatric Press, Washington DC, 1992). Seventy-eight percent of atypical depressives met criteria for bipolar spectrum-principally bipolar II-disorder. Forty-five patients who met the criteria for cyclothymic temperament, compared with the 62 who did not, were indistinguishable on demographic, familial and clinical features, but were significantly higher in lifetime comorbidity for panic disorder with agoraphobia, alcohol abuse, bulimia nervosa, as well as borderline and dependent personality disorders. Cyclothymic atypical depressives also scored higher on the ADDS items of maximum reactivity of mood, interpersonal sensitivity, functional impairment, avoidance of relationships, other rejection avoidance, and on the interpersonal sensitivity, phobic anxiety, paranoid ideation and psychoticism of the HSCL-90 factors. The total number of cyclothymic traits was significantly correlated with 'maximum' reactivity of mood and interpersonal sensitivity. A significant correlation was also found between interpersonal sensitivity and 'usual' and 'maximum' reactivity of mood. Correlational study. Mood lability and interpersonal sensitivity traits appear to be related by a cyclothymic temperamental diathesis which, in turn, appears to underlie the complex pattern of anxiety, mood and impulsive disorders which atypical depressive, bipolar II and borderline patients display clinically. We submit that conceptualizing these constructs as being related will make patients in this realm more accessible to pharmacological and psychological interventions geared to their common temperamental attributes. More generally, we submit that the construct of borderline personality disorder is better covered by more conventional diagnostic entities.

Free energy simulations compare multiple ligand:receptor complexes by "alchemically" transforming one into another, yielding binding free energy differences. Since their introduction in the 1980s, many technical and theoretical obstacles were surmounted, and the method ("MDFE," since molecular dynamics are often used) has matured into a powerful tool. We describe its current status, its effectiveness, and the challenges it faces. MDFE has provided chemical accuracy for many systems but remains expensive, with significant human overhead costs. The bottlenecks have shifted, partly due to increased computer power. To study diverse sets of ligands, force field availability and accuracy can be a major difficulty. Another difficulty is the frequent need to consider multiple states, related to sidechain protonation or buried waters, for example. Sophisticated, automated methods to sample these states are maturing, such as constant pH simulations. Meanwhile, combinations of MDFE and simpler approaches, like continuum dielectric models, can be very effective. As illustrations, we show how, with careful force field parameterization, MDFE accurately predicts binding specificities between complex tetracycline ligands and their targets. We describe substrate binding to the aspartyl-tRNA synthetase enzyme, where many distinct electrostatic states play a role, and a histidine and a Mg(2+) ion act as coupled switches that help enforce a strict preference for the aspartate substrate, relative to several analogs. Overall, MDFE has achieved a predictive status, where novel ligands can be studied and molecular recognition elucidated in depth. It should play an increasing role in the analysis of complex cellular processes and biomolecular engineering. 2009 John Wiley & Sons, Ltd.

To examine factors increasing the risk for onset and persistence of subthreshold mania and depression. In a prospective cohort community study, the association between risk factors [a family history of mood disorders, trauma, substance use, attention-deficit/hyperactivity disorder (ADHD) and temperamental/personality traits] and onset of manic/depressive symptoms was determined in 705 adolescents. The interaction between baseline risk factors and baseline symptoms in predicting 8-year follow-up symptoms was used to model the impact of risk factors on persistence. Onset of manic symptoms was associated with cannabis use and novelty seeking (NS), but NS predicted a transitory course. Onset of depressive symptoms was associated with a family history of depression. ADHD and harm avoidance (HA) were associated with persistence of depressive symptoms, while trauma and a family history of depression predicted a transitory course. Different risk factors may operate during onset and persistence of subthreshold mania and depression. The differential associations found for mania and depression dimensions suggest partly different underlying mechanisms.

Behavioral inhibition (BI) is a risk factor for anxiety disorders. While the two constructs bear behavioral similarities, previous work has not extended these parallels to the neural level. This study examined amygdala reactivity during a task previously used with clinically anxious adolescents. Adolescents were selected for enduring patterns of BI or non-inhibition (BN). We examined amygdala response to evocative emotion faces in BI (N=10, mean 12.8 years) and BN (N=17, mean 12.5 years) adolescents while systematically manipulating attention. Analyses focused on amygdala response during subjective ratings of internal fear (constrained attention) and passive viewing (unconstrained attention) during the presentation of emotion faces (Happy, Angry, Fearful, and Neutral). BI adolescents, relative to BN adolescents, showed exaggerated amygdala response during subjective fear ratings and deactivation during passive viewing, across all emotion faces. In addition, the BI group showed an abnormally high amygdala response to a task condition marked by novelty and uncertainty (i.e., rating fear state to a Happy face). Perturbations in amygdala function are evident in adolescents temperamentally at risk for anxiety. Attention state alters the underlying pattern of neural processing, potentially mediating the observed behavioral patterns across development. BI adolescents also show a heightened sensitivity to novelty and uncertainty, which has been linked to anxiety. These patterns of reactivity may help sustain early temperamental biases over time and contribute to the observed relation between BI and anxiety. PMID:17376704

There are marked individual differences in the pattern of cortical (sulcogyral) folding in the orbitofrontal cortex (OFC), and there is a growing literature suggesting that these individual differences are associated with risk for psychotic disorders. To date, however, no study has investigated whether OFC folding patterns are associated with broader risk factors relevant to a range of psychopathology. This study helps address this knowledge gap by examining whether OFC sulcogyral folding patterns are associated with putative risk factors, specifically affective temperament and psychiatric symptoms, in a large community sample (N = 152) of adolescents. Results showed that the most common pattern of folding ('Type I', marked by discontinuity of the medial orbital sulcus and continuity of the lateral orbital sulcus) was associated with low levels of Surgency, high levels of Negative Affectivity (in girls) and higher depressive symptoms. This pattern was also associated with reduced thickness of OFC gray matter. Overall, the findings, combined with previous work, suggest some specificity of neurodevelopmental risk for different types of psychopathology. Thus, these results have the potential to inform the early identification of at-risk individuals.

This study examined how coparenting and firstborn children's temperament predicted children's cooperative behavior in response to maternal requests for assistance in the care of a 1-month-old infant sibling. Children's cooperative responding was observed during a diaper change session for 216 firstborns (ages 13 to 70 months; M = 32). Parents also completed questionnaires assessing coparenting and children's temperament. Results suggested that coparenting quality moderated the association between children's temperament (i.e., soothability) and children's cooperation as revealed in a Temperament × Cooperative Coparenting × Undermining Coparenting interaction. Specifically, low soothability predicted low levels of children's cooperation in families with high undermining and low cooperative coparenting, over and above the effects of child age, gender, and mothers' education. Findings further our understanding of how temperamental characteristics and coparenting quality conjointly predict individual differences in firstborn children's positive adjustment across the transition to siblinghood.

Developing mechanisms of self-regulation.

Child development involves both reactive and self-regulatory mechanisms that children develop in conjunction with social norms. A half-century of research has uncovered aspects of the physical basis of attentional networks that produce regulation, and has given us some knowledge of how the social environment may alter them. In this paper, we discuss six forms of developmental plasticity related to aspects of attention. We then focus on effortful or executive aspects of attention, reviewing research on temperamental individual differences and important pathways to normal and pathological development. Pathologies of development may arise when regulatory and reactive systems fail to reach the balance that allows for both self-expression and socially acceptable behavior. It remains a challenge for our society during the next millennium to obtain the information necessary to design systems that allow a successful balance to be realized by the largest possible number of children.

Dysfunctional voiding (DV) is an extremely common pediatric complaint. The goal of this study was to examine the relationship between DV and childhood temperament. Information about the voiding behaviors and temperaments of 50 children was examined using a case-control model. Caregivers were asked to fill out the Children's Behavior Questionnaire in order to rate their child on the dimensions of surgency, negative affect, and effortful control. The relationship between DV and these dimensions was then evaluated. Males with DV were found to have lower effortful control than males with normal voiding habits. Females with DV did not demonstrate a difference in effortful control, but did demonstrate a higher rate of surgency. The results suggest that temperament does have an association with DV. These findings are in line with temperamental associations with other externalizing trouble behaviors and may inform potential treatment strategies for DV.

More than just noise: Inter-individual differences in fear acquisition, extinction and return of fear in humans - Biological, experiential, temperamental factors, and methodological pitfalls.

Why do only some individuals develop pathological anxiety following adverse events? Fear acquisition, extinction and return of fear paradigms serve as experimental learning models for the development, treatment and relapse of anxiety. Individual differences in experimental performance were however mostly regarded as 'noise' by researchers interested in basic associative learning principles. Our work for the first time presents a comprehensive literature overview and methodological discussion on inter-individual differences in fear acquisition, extinction and return of fear. We tell a story from noise that steadily develops into a meaningful tune and converges to a model of mechanisms contributing to individual risk/resilience with respect to fear and anxiety-related behavior. Furthermore, in light of the present 'replicability crisis' we identify methodological pitfalls and provide suggestions for study design and analyses tailored to individual difference research in fear conditioning. Ultimately, synergistic transdisciplinary and collaborative efforts hold promise to not only improve our mechanistic understanding but can also be expected to contribute to the development of specifically tailored ('individualized') intervention and targeted prevention programs in the future.

Maternal antenatal mood is associated with negative infant temperament. This link has not been substantiated in Asian populations. We evaluated the association between antenatal maternal mood and infant temperament among Asian mother-infant pairs. Antenatal maternal depression and anxiety were assessed using the Edinburgh Postnatal Depression Scale (J. Cox, J. Holden, & R. Sagovsky, 1987) and the State-Trait Anxiety Inventory (C. Spielberger, R. Gorsuch, R. Lushene, P. Vagg, & G. Jacobs, 1983), respectively, at 26 weeks of pregnancy and 3 months' postnatally. Infant temperament was evaluated with the Early Infant Temperament Questionnaire (B. Medoff-Cooper, W.B. Carey, & S.C. McDevitt, 1993) at 3 months. Factor analysis was performed to extract culturally relevant categories of temperamental traits. Linear regression was performed to examine the influences of antenatal maternal mood on the factor-model-derived infant temperament. Of the 609 mothers, 11% met risk criteria for depression, 17% for state-anxiety, and 19% for trait-anxiety during pregnancy. Factor analysis yielded three infant temperament factors: Emotionality and Attentional Regulation, Sensory Reactivity, and Regularity and Motor Expression, Cronbach's αs = 0.613, 0.712, and 0.752, respectively. Maternal antenatal state-anxiety, p < .001, and trait anxiety, p = .005, were associated with negative emotionality and poor attentional regulation, especially among Chinese, whereas depression was not, p = .090. There was an association between maternal antenatal anxiety and negative infant temperamental traits in this Asian sample. © 2016 Michigan Association for Infant Mental Health.

Temperamental workers: Psychology, business, and the Humm-Wadsworth Temperament Scale in interwar America.

PubMed

Lussier, Kira

2018-05-01

This article traces the history of a popular interwar psychological test, the Humm-Wadsworth Temperament Scale (HWTS), from its development in the early 1930s to its adoption by corporate personnel departments. In popular articles, trade magazines, and academic journals, industrial psychologist Doncaster Humm and personnel manager Guy Wadsworth trumpeted their scale as a scientific measure of temperament that could ensure efficient hiring practices and harmonious labor relations by screening out "problem employees" and screening for temperamentally "normal" workers. This article demonstrates how concerns about the epistemological and scientific credibility of the HWTS were intimately entangled with concerns about its value to business at every step in the test's development. The HWTS sought to measure the emotional and social dimensions of an individual's personality so as to assess their suitability for work. The practice of temperament testing conjured a vision of the subject whose emotional and social disposition was foundational to their own capacity to find employment, and whose capacity to appropriately express, but regulate, their emotions was foundational to corporate order. The history of the HWTS offers an instructive case of how psychological tests embed social hierarchies, political claims, and economic ideals within their very theoretical and methodological foundations. Although the HWTS itself may have faded from use, the test directly inspired creators of subsequent popular personality tests, such as the Minnesota Multiphasic Personality Inventory and the Myers-Briggs Type Indicator.

Objective We examined whether some temperamental traits would be associated with persistence of attention deficit-hyperacitivty disorder (ADHD) in adulthood independent from bipolar disorder (BD). Methods Eighty-one ADHD patients without a comorbid diagnosis of BD were divided into two groups, those with childhood ADHD (n=46), and those with Adulthood ADHD (n=35). The severity of childhood and adulthood ADHD were assessed by using the Wender Utah Rating Scale (WURS-25) and Turgay’s Adult ADD/ADHD Diagnosis and Evaluation Scale (DES). Subjects’ temperamental characteristics were examined using the Temperament Evaluation of Memphis, Pisa, Paris and San Diego-auto questionnaire (TEMPS-A). Results The mean scores of WURS-25 were higher in adult ADHD group than in childhood ADHD group (p<0.001). Adult ADHD group had significantly higher scores on cyclothymic (p=0.002), irritable (p<0.0001), and anxious (p=0.042) subscales of TEMPS-A. The scores of WURS-25 in adulthood ADHD group were positively correlated with cyclothymia scores (r=0.366, p=0.033). Total scores of Turgay’s Adult ADD/ADHD DES were positively correlated with cyclothymic (r=0.354, p=0.040), hyperthymic (r=0.380, p=0.026), and irritable (r=0.380, p=0.026) subscale scores. Cychlothymic and irritable temperaments were significantly associated with the severity of adulthood symptoms of ADHD. Conclusion We might suggest that cyclothymic and irritable temperaments would predict the diagnosis of adulthood ADHD independent from BD. PMID:29475238

Relative Age Effects in Dutch Adolescents: Concurrent and Prospective Analyses

The literature on relative age position effects is rather inconsistent. In this study we examined intra-classroom age position (or relative age) effects on Dutch adolescents’ school progress and performance (as rated by teachers), physical development, temperamental development (fear and frustration), and depressive symptoms, all adjusted for age at the time of measurement. Data were derived from three waves of Tracking Adolescents' Individuals Lives Survey (TRAILS) of 2230 Dutch adolescents (baseline mean age 11.1, SD = 0.6, 51% girls). Albeit relative age predicted school progress (grade retention ORs = 0.83 for each month, skipped grade OR = 1.47, both p<.001), our key observation is the absence of substantial developmental differences as a result of relative age position in Dutch adolescents with a normative school trajectory, in contrast to most literature. For adolescents who had repeated a grade inverse relative age effects were observed, in terms of physical development and school performance, as well as on depressive symptoms, favoring the relatively young. Cross-cultural differences in relative age effect may be partly explained by the decision threshold for grade retention. PMID:26076384

Annual Research Review: An expanded account of information-processing mechanisms in risk for child and adolescent anxiety and depression.

Lau, Jennifer Y F; Waters, Allison M

Anxiety and depression occurring during childhood and adolescence are common and costly. While early-emerging anxiety and depression can arise through a complex interplay of 'distal' factors such as genetic and environmental influences, temperamental characteristics and brain circuitry, the more proximal mechanisms that transfer risks on symptoms are poorly delineated. Information-processing biases, which differentiate youth with and without anxiety and/or depression, could act as proximal mechanisms that mediate more distal risks on symptoms. This article reviews the literature on information-processing biases, their associations with anxiety and depression symptoms in youth and with other distal risk factors, to provide direction for further research. Based on strategic searches of the literature, we consider how youth with and without anxiety and/or depression vary in how they deploy attention to social-affective stimuli, discriminate between threat and safety cues, retain memories of negative events and appraise ambiguous information. We discuss how these information-processing biases are similarly or differentially expressed on anxiety and depression and whether these biases are linked to genetic and environmental factors, temperamental characteristics and patterns of brain circuitry functioning implicated in anxiety and depression. Biases in attention and appraisal characterise both youth anxiety and depression but with some differences in how these are expressed for each symptom type. Difficulties in threat-safety cue discrimination characterise anxiety and are understudied in depression, while biases in the retrieval of negative and overgeneral memories have been observed in depression but are understudied in anxiety. Information-processing biases have been studied in relation to some distal factors but not systematically, so relationships remain inconclusive. Biases in attention, threat-safety cue discrimination, memory and appraisal may characterise anxiety and/or depression risk. We discuss future research directions that can more systematically test whether these biases act as proximal mechanisms that mediate other distal risk factors. © 2016 The Authors.

Temperamental precursors of infant attachment with mothers and fathers☆

2013-01-01

The degree to which parent sensitivity and infant temperament distinguish attachment classification was examined. Multilevel modeling was used to assess the effect of parent sensitivity and infant temperament on infant–mother and infant–father attachment. Data were collected from mothers, fathers, and their infants (N = 135) when the infant was 3-, 5-, 7-, 12-, and 14-months old. Temperament was measured using the Infant Behavior Questionnaire-Revised (Gartstein & Rothbart, 2003); parent sensitivity was coded during the Still Face Paradigm (Tronick, Als, Adamson, Wise, & Brazelton, 1978); attachment was coded using the Strange Situation (Ainsworth, Blehar, Waters, & Wall, 1978). Results indicate that mothers and fathers were less sensitive with insecure-avoidant infants. Whereas only one difference was found for infant–mother attachment groups and temperament, five significant differences emerged for infant–father attachment groups, with the majority involving insecure-ambivalent attachment. Infants classified as ambivalent with fathers were higher in perceptual sensitivity and cuddliness and these infants also showed a greater increase in low-intensity pleasure over time compared with other infants. Results indicate the importance of both parent sensitivity and infant temperament, though operating in somewhat different ways, in the development of the infant–mother and infant–father attachment relationship.

Personality neuroscience defines the scientific study of the neurobiological basis of personality. This field assumes that individual differences in personality traits are related with structural and functional variations of the human brain. Gray and white matters are structural properties considered separately in previous research. Available findings in this regard are largely disparate. Here we analyze the relationships between gray matter (cortical thickness (CT), cortical surface area (CSA), and cortical volume) and integrity scores obtained after several white matter tracts connecting different brain regions, with individual differences in the personality traits comprised by the Five-Factor Model (extraversion, agreeableness, conscientiousness, neuroticism, and openness to experience). These psychological and biological data were obtained from young healthy women. The main findings showed statistically significant associations between occipital CSA variations and extraversion, as well as between parietal CT variations and neuroticism. Regarding white matter integrity, openness showed positive correlations with tracts connecting posterior and anterior brain regions. Therefore, variations in discrete gray matter clusters were associated with temperamental traits (extraversion and neuroticism), whereas long-distance structural connections were related with the dimension of personality that has been associated with high-level cognitive processes (openness).

Outdoor free play is important for preschoolers' physical activity, health, and development. Certain temperamental characteristics are associated with obesity, nutrition, and sedentary behaviors in preschoolers, but the relationship between temperament and outdoor play has not been examined. This study examined whether there is an association between temperament and outdoor play in young children. Healthy children aged 1 to 5 years recruited to The Applied Research Group for Kids (TARGet Kids!), a community-based primary care research network, from July 2008 to September 2013 were included. Parent-reported child temperament was assessed using the Childhood Behavior Questionnaire. Outdoor free play and other potential confounding variables were assessed through validated questionnaires. Multivariable linear regression was used to determine the association between temperament and outdoor play, adjusted for potential confounders. There were 3393 children with data on outdoor play. The association between negative affectivity and outdoor play was moderated by sex; in boys, for every 1-point increase in negative affectivity score, mean outdoor play decreased by 4.7 minutes per day. There was no significant association in girls. Surgency was associated with outdoor play; for every 1-point increase in surgency/extraversion, outdoor play increased by 4.6 minutes per day. Young children's temperamental characteristics were associated with their participation in outdoor free play. Consideration of temperament could enhance interventions and strategies to increase outdoor play in young children. Longitudinal studies are needed to elucidate the relationship between children's early temperament and physical activity. Copyright © 2017 Academic Pediatric Association. Published by Elsevier Inc.

Appraisal and coping styles account for the effects of temperament on preadolescent adjustment

Temperament, appraisal, and coping are known to underlie emotion regulation, yet less is known about how these processes relate to each other across time. We examined temperamental fear, frustration, effortful control, and impulsivity, positive and threat appraisals, and active and avoidant coping as processes underpinning the emotion regulation of pre-adolescent children managing stressful events. Appraisal and coping styles were tested as mediators of the longitudinal effects of temperamental emotionality and self-regulation on adjustment using a community sample (N=316) of preadolescent children (8–12 years at T1) studied across one year. High threat appraisals were concurrently related to high fear and impulsivity, whereas effortful control predicted relative decreases in threat appraisal. High fear was concurrently related to high positive appraisal, and impulsivity predicted increases in positive appraisal. Fear was concurrently related to greater avoidant coping, and impulsivity predicted increases in avoidance. Frustration predicted decreases in active coping. These findings suggest temperament, or dispositional aspects of reactivity and regulation, relates to concurrent appraisal and coping processes and additionally predicts change in these processes. Significant indirect effects indicated that appraisal and coping mediated the effects of temperament on adjustment. Threat appraisal mediated the effects of fear and effortful control on internalizing and externalizing problems, and avoidant coping mediated the effect of impulsivity on internalizing problems. These mediated effects suggest that one pathway through which temperament influences adjustment is pre-adolescents’ appraisal and coping. Findings highlight temperament, appraisal and coping as emotion regulation processes relevant to children’s adjustment in response to stress. PMID:25821237

Behavioral inhibition (BI) to the unfamiliar represents the temperamental tendency to exhibit fearfulness, reticence, or restraint when faced with unfamiliar people or situations. It has been hypothesized to be a risk factor for anxiety disorders. In this prospective longitudinal study, we compared the psychiatric outcomes in middle childhood of children evaluated at preschool age for BI. The baseline sample consisted of 284 children ages 21 months to 6 years, including offspring at risk for anxiety (children of parents with panic disorder and/or major depression) and comparison offspring of parents without mood or major anxiety disorders. They had been assessed for BI using age-specific laboratory protocols. We reassessed 215 of the children (76.5%) at 5-year follow-up at a mean age of 9.6 years using structured diagnostic interviews. BI specifically predicted onset of social anxiety. The rate of lifetime social anxiety (DSM-IV social phobia or DSM-III-R avoidant disorder) was 28% versus 14% (odds ratio [OR] = 2.37; 95% confidence interval [CI]: 1.10-5.10) in inhibited versus noninhibited children. BI significantly predicted new onset of social phobia among children unaffected at baseline (22.2% vs 8.0% in inhibited versus noninhibited children (OR = 3.15, 95% CI: 1.16-8.57). No other anxiety disorders were associated with BI. BI appears to be a temperamental antecedent to subsequent social anxiety in middle childhood. Children presenting with BI should be monitored for symptoms of social anxiety and may be good candidates for preventive cognitive behavioral strategies.

A common variant (rs53576) of the OXTR gene has been implicated in a number of socio-emotional phenotypes, such as anxiety-related behavior. Previous studies have demonstrated that A-allele carriers have higher levels of physiological and dispositional stress reactivity and depressive symptomatology compared to those with the GG genotype, but the mediating neural mechanisms remain poorly understood. We combined voxel-based morphometry and resting-state functional connectivity analyses in a large cohort of healthy young Chinese Han individuals to test the hypothesis that the OXTR gene polymorphism influences an anxiety-related temperamental trait, as assessed by the harm avoidance subscale from the Tridimensional Personality Questionnaire via modulating the gray matter volume and resting-state functional connectivity of the brain, especially the limbic system. We revealed that female subjects with the AA genotype showed increased harm avoidance scores relative to G-carrier females. We also found that, compared to female individuals with the GG/GA genotype, female individuals with the AA genotype exhibited significantly smaller amygdala volumes bilaterally (especially the centromedial subregion), with a trend of allele-load-dependence. Compared to female individuals with the GG/GA genotype, female subjects with the AA genotype demonstrated reduced resting-state functional coupling between the prefrontal cortex and amygdala bilaterally, also with an allele-load-dependent trend. Furthermore, the magnitude of prefrontal-amygdala coupling in the left hemisphere was positively correlated with harm avoidance scores in female subjects. Our findings highlight a possible neural pathway by which a naturally occurring variation of the OXTR gene may affect an anxiety-related temperamental trait in female subjects by modulating prefrontal-amygdala functional connectivity.

Child temperament as well as parenting behaviors have been linked to adolescent depression. Beyond their main effects, the interplay between these factors is of interest. For example, in an interactive model, a differential susceptibility of temperamental variants to parenting has been suggested. However, so far, the differential susceptibility hypothesis has mostly been studied with a focus on externalizing disorders. On the other hand, parenting may shape the child's temperament and vice versa in a transactional process. In a prospective, longitudinal at-risk sample (163 boys, 176 girls), we assessed emotional (easy-difficult) and regulative (self-control) temperament at ages 4.5, and 8 years, respectively, as well as parenting quality at age 4.5 years using the HOME inventory. Hierarchical linear regression analysis was used to investigate the prediction of depressive symptoms at age 11, measured by the Child Depression Inventory, including interaction terms between the temperament variable and parenting. We additionally tested whether parenting was mediated by child temperament. As previously reported, both self-control and parenting were longitudinally associated with preadolescent depressive symptoms. There were no interactive effects between temperament and parenting. However, the effects of parenting were partly mediated by self-control. Our data do not support a differential susceptibility of temperamental variants in the development of preadolescent depression. However, our results are in line with the assumption that parenting may shape young children's temperament, with positive parenting in the early childhood fostering the development of regulative temperament.

Memories and traces. From Jewish exilists' authoritarian personality research via Cloninger's psychobiology of personality traits to a neurobiological approach to conflict management.

PubMed

Hassler, Marianne

2002-01-01

Research on personality as a useful construct to understand people's behavior in conflict situations was traced over more than fifty years, and an attempt was made to add neurobiological parameters to psycho-socio-cultural approaches. As a starting point, scientists in exile have been called to mind who had been expelled from Nazi Germany for their Jewish origins. Among them were Adorno and Frenkel-Brunswik whose extensive studies on the authoritarian personality structure were quoted. In their work, personality was defined as a more or less enduring organisation of forces within the individual helping to determine responses in various situations, which is responsible for consistency in behavior. As a next step, Cloninger's psychobiology of personality traits was presented. In his personality concept, four temperamental traits (novelty seeking, harm avoidance, reward dependency and persistence) and three character dimensions are included. Temperamental traits are heritable, developmentally stable, emotionally based, uninfluenced by social learning, and linked to specific brain biological features. The temperaments have a certain neuroendocrinological feature which can be determined. Character dimensions develop in a stagelike process from infancy to adulthood and are influenced by temperament, social learning, genetic factors, and random life events. Personality is still considered a useful theoretical approach to conflict management research and practice. A neurobiological point of view seems to be a useful supplementation in addition to traditional psycho-socio-cultural approaches. Measuring biological compounds can supply the conflict manager with an additional tool of knowledge enhancing the ability to understand and anticipate conflict behavior.

This study assessed the prevalence of anxiety disorders in preschool children and their associations with behavioral inhibition as a temperamental precursor. A representative sample of 1,342 children aged 4–7 years (M = 6;1, SD = 4.80) was examined with a standardized parental questionnaire, including items referring to anxiety disorders at the current age and behavioral inhibition at the age of 2 years. The total prevalence of anxiety disorders was 22.2 %. Separation anxiety (SAD) affected 7 %, social phobia (SOC) 10.7 %, specific phobia (PHOB) 9.8 % and depression/generalized anxiety (MDD/GAD) 3.4 % of children. The prevalence of most types of anxiety was higher in girls except for separation anxiety, which affected more boys. Behavioral inhibition in the second year of life was associated with all types of anxiety. Anxiety disorders are common but frequently overlooked in preschool children. Different subtypes can be differentiated and are often preceded by behavioral inhibition. Assessment, prevention and treatment of anxiety disorders are recommended in preschool children.

Temperamental Differences in Children’s Reactions to Peer Victimization

Objective This research examined the hypothesis that temperament and sex moderate the contribution of peer victimization to children’s subsequent adjustment (aggression and depressive symptoms). Method Children (125 boys, 158 girls; M age = 7.95 years, SD = 0.32; 77.7% White, 22.3% minority) and teachers reported on overt and relational victimization. Parents rated children’s temperament (inhibitory control and negative emotionality) and depressive symptoms, and teachers reported on children’s overt and relational aggression. Results Across a one-year time period, (a) overt victimization predicted overt aggression in girls with poor inhibitory control; (b) overt and relational victimization predicted depressive symptoms in girls with high negative emotionality; and (c) relational victimization predicted depressive symptoms in boys with low negative emotionality. Conclusions This research helps to explain individual variation in children’s reactions to peer victimization, and has implications for person-by-environment models of development. Moreover, this research informs the development of targeted intervention programs for victimized youth that bolster specific resources depending on their temperament. PMID:22420650

Sexually dimorphic effects of oxytocin receptor gene (OXTR ) variants on Harm Avoidance.

2012-07-30

Recent research has suggested that oxytocin receptor gene (OXTR) variants may account for individual differences in social behavior, the effects of stress and parenting styles. Little is known, however, on a putative role of the gene in heritable temperamental traits. We addressed effects of two common OXTR variants, rs237900 and rs237902, on personality dimensions in 99 healthy subjects using the Temperament and Character Inventory. When sex was controlled for and an OXTR genotype*sex interaction term was included in the regression model, 11% of the variance in Harm Avoidance could be explained (uncorrected p ≤ 0.01). Female carriers of the minor alleles scored highest, and a novel A217T mutation emerged in the most harm avoidant male participant. Findings lend support to a modulatory effect of common OXTR variants on Harm Avoidance in healthy caucasian women and invite resequencing of the gene in anxiety phenotypes to identify more explanatory functional variation.

Poor effortful control is a key temperamental factor underlying behavioral problems. The bidirectional association of child effortful control with both positive parenting and negative discipline was examined from ages approximately 3 to 13-14 years, involving five time points, and using data from parents and children in the Oregon Youth Study-Three Generational Study (N = 318 children from 150 families). Based on a dynamic developmental systems approach, it was hypothesized that there would be concurrent associations between parenting and child effortful control and bidirectional effects across time from each aspect of parenting to effortful control and from effortful control to each aspect of parenting. It was also hypothesized that associations would be more robust in early childhood, from ages 3 to 7 years, and would diminish as indicated by significantly weaker effects at the older ages, 11-12 to 13-14 years. Longitudinal feedback or mediated effects were also tested. The findings supported (a) stability in each construct over multiple developmental periods; (b) concurrent associations, which were significantly weaker at the older ages; (c) bidirectional effects, consistent with the interpretation that at younger ages children's effortful control influenced parenting, whereas at older child ages, parenting influenced effortful control; and (d) a transactional effect, such that maternal parenting in late childhood was a mechanism explaining children's development of effortful control from middle childhood to early adolescence.

Findings supported (a) stability in each construct over multiple developmental periods; (b) concurrent associations, which were significantly weaker at the older ages; (c) bidirectional effects, consistent with the interpretation that at younger ages children’s effortful control influenced parenting, whereas at older child ages, parenting influenced effortful control; and (d) a transactional effect, such that maternal parenting in late childhood was a mechanism explaining children’s development of effortful control from midchildhood to early adolescence.

Research suggests that abuser risk factors differ across elder mistreatment types, but abuse interventions are not individualized. To move away from assumptions of perpetrator homogeneity and to inform intervention approaches, this study classifies abusers into subtypes according to their behavior profiles. Data are from the Older Adult Mistreatment Assessment administered to victims by Adult Protective Service (APS) in Illinois. Latent class analysis was used to categorize abusers (N = 336) using victim and caseworker reports on abusers' harmful and supportive behaviors and characteristics. Multinomial logistic regression was then used to determine which abuser profiles are associated with 4 types of mistreatment-neglect, physical, emotional, and financial-and other sociodemographic characteristics. Abusers fall into 4 profiles descriptively labeled "Caregiver," "Temperamental," "Dependent Caregiver," and "Dangerous." Dangerous abusers have the highest levels of aggression, financial dependency, substance abuse, and irresponsibility. Caregivers are lowest in harmful characteristics and highest in providing emotional and instrumental support to victims. The 4 profiles significantly differ in the average age and gender of the abuser, the relationship to victims, and types of mistreatment committed. This is the first quantitative study to identify and characterize abuser subtypes. Tailored interventions are needed to reduce problem behaviors and enhance strengths specific to each abuser profile.

Temperaments have been described with respect to their adaptive roles. Thus, depressive traits seem to increase sensitivity to suffering, cyclothymic traits appear relevant to creativity, and hyperthymic traits have been implicated in territoriality and leadership and more generally in active pursuits. The temperaments of 1548 candidates applying to become a cadet officer in the Italian air force, who had taken the 2005 entrance examination, were compared with deviant and non-deviant peers. At a psychological level, we also compared those who had applied to become a cadet officer with other applicants who had failed in a previous entrance examination and with applicants who had passed or failed to pass the specific psychological entrance examination. Applicants who took the entrance examination are more hyperthymic than their peers, regardless of any concurrent psychosocial deviance (i.e. drug addiction). The specificity of this correlation is confirmed by the fact that applicants who made a second attempt to pass the entrance examination after an initial failure were more hyperthymic than first-time applicants. Similarly, success in specific psychological admission tests is related to the same temperamental profiles, since those who prove to be psychologically fit are more hyperthymic. The inverse relationship emerges from an examination of other temperamental scales, which are better represented in controls (non-applicants), or other applicants making their first attempt at admission, or those who were excluded due to psychological flaws. In the present study, extremely high scores on the hyperthymic scale combined with extremely low ones in the cyclothymic scale seem to correspond to the specific temperament profile and to the highest likelihood of success in those applying to become a cadet officer in the Italian air force.

Latent Class Symptom Profiles of Selective Mutism: Identification and Linkage to Temperamental and Social Constructs.

PubMed

Diliberto, Rachele; Kearney, Christopher A

2017-11-21

Selective mutism (SM) is a stable, debilitating psychiatric disorder in which a child fails to speak in most public situations. Considerable debate exists as to the typology of this population, with empirically-based studies pointing to possible dimensions of anxiety, oppositionality, and communication problems, among other aspects. Little work has juxtaposed identified symptom profiles with key temperamental and social constructs often implicated in SM. The present study examined a large, diverse, non-clinical, international sample of children aged 6-10 years with SM to empirically identify symptom profiles and to link these profiles to key aspects of temperament (i.e., emotionality, shyness, sociability, activity) and social functioning (i.e., social problems, social competence). Exploratory and confirmatory factor analysis revealed anxiety/distress, oppositionality, and inattention domains. In addition, latent class analysis revealed nuanced profiles labeled as (1) moderately anxious, oppositional, and inattentive, (2) highly anxious, and moderately oppositional and inattentive, and (3) mildly to moderately anxious, and mildly oppositional and inattentive. Class 2 was the most impaired group and was associated with greater emotionality, shyness, and social problems. Class 3 was the least impaired group and was associated with better sociability and social competence and activity. Class 1 was largely between the other classes, demonstrating less shyness and social problems than Class 2. The results help confirm previous findings of anxiety and oppositional profiles among children with SM but that nuanced classes may indicate subtle variations in impairment. The results have implications not only for subtyping this population but also for refining assessment and case conceptualization strategies and pursuing personalized and perhaps less lengthy treatment.

Early temperamental characteristics may influence children's developmental pathways and predict future psychopathology. However, the environmental context may also shape or interact with infant temperament and indirectly contribute to increased vulnerability to adverse developmental outcomes. The aim of the present study is to explore the long-term contribution of temperamental traits at twelve months of age to the presence of emotional and behavioral problems later in childhood, and whether this association varies with the child's sex, parental separation, family socioeconomic status and maternal depression. 1184 mother-child pairs from the EDEN mother-child birth cohort study based in France (2003-2011), were followed from 24-28 weeks of pregnancy to the child's fifth birthday. Infant temperament at 12 months was assessed with the Emotionality Activity and Sociability (EAS) questionnaire and behavior at 5.5 years was assessed with the Strengths and Difficulties Questionnaire (SDQ). Emotional temperament in infancy predicts children's overall behavioral scores (β = 1.16, p<0.001), emotional difficulties (β = 0.30, p<0.001), conduct problems (β = 0.51, p<0.001) and symptoms of hyperactivity/inattention (β = 0.31, p = 0.01) at 5.5 years. Infants' active temperament predicts later conduct problems (β = 0.30, p = 0.02), while shyness predicts later emotional problems (β = 0.22, p = 0.04). The association between the child's temperament in infancy and later behavior did not vary with children's own or family characteristics. An emotional temperament in infancy is associated with higher levels of emotional and behavioral difficulties at the age of 5.5 years. Children who show high emotionality early on may require early prevention and intervention efforts to divert possible adverse developmental pathways.

According to diathesis-stress models, temperament traits, such as negative emotionality (NE), may moderate the effects of stressors on the development of symptoms of psychopathology, although very little research has tested such models in children. Moreover, there are few data on whether specific facets of NE (sadness, fear, or anger) may specifically moderate the effects of stress on depression versus anxiety. Finally, there is a paucity of research examining whether childhood temperament moderates the effect of disaster exposure on depressive or anxiety symptoms. Hurricane Sandy, which affected many thousands of people in New York State and surrounding regions in October 2012, offers a unique opportunity to address these gaps. Seven years prior to Hurricane Sandy, 332 three-year-old children completed lab-based measures of NE and its facets. Six years later, when they were nine years old, one parent rated their child’s depressive and anxiety symptoms. Approximately eight weeks post-Sandy (an average of one year after the age nine assessment), a parent again rated their child’s depressive and anxiety symptoms, as well as a measure of exposure to stress from Hurricane Sandy. Adjusting for symptom levels at age 9, higher levels of stress from Hurricane Sandy predicted elevated levels of depressive symptoms only in participants with high levels of temperamental sadness, and predicted elevated levels of anxiety symptoms only in participants high in temperamental fearfulness. These findings support the role of early childhood temperament as a diathesis for psychopathology, and highlight the importance of considering facets of temperament when examining their relationship to psychopathology.

We examined whether the temperament of behavioral inhibition is a significant marker for psychopathology in early adulthood and whether such risk is buffered by peer social networks. Participants (N = 165) were from a prospective study spanning the first two decades of life. Temperament was characterized during infancy and early childhood. Extent of involvement in peer social networks was measured during adolescence, and psychopathology was assessed in early adulthood. Latent Class Analyses generated comprehensive variables at each of three study time-points. Regressions assessed (a) the direct effect of early behavioral inhibition on adult psychopathology (b) the moderating effect of adolescent involvement in social peer networks on the link between temperamental risk and adult psychopathology. Stable behavioral inhibition in early childhood was negatively associated with adult mental health (R(2 ) = .07, p = .005, β = -.26), specifically increasing risk for adult anxiety disorders (R(2) = .04, p = .037, β = .19). These temperament-pathology relations were significantly moderated by adolescent peer group social involvement and network size (Total R(2) = .13, p = .027, β = -.22). Temperament predicted heightened risk for adult anxiety when adolescent social involvement was low (p = .002, β = .43), but not when adolescent social involvement was high. Stable behavioral inhibition throughout early childhood is a risk factor for adult anxiety disorders and interacts with adolescent social involvement to moderate risk. This is the first study to demonstrate the critical role of adolescent involvement in socially active networks in moderating long-lasting temperamental risk over the course of two decades, thus informing prevention/intervention approaches. © 2015 Association for Child and Adolescent Mental Health.

Growing number of studies indicates a link between eveningness chronotype, affective temperaments and bipolarity, both in patients with mood disorders and in general population. Given these tripartite associations, we hypothesized that the effect of circadian preferences on the bipolarity may be mediated by the temperamental traits. The study included 1449 subjects (402 men and 1047 women). They all fulfilled a web-based questionnaire, consisting of the Composite Scale of Morningness (CSM), Mood Disorder Questionnaire (MDQ), Hypomania Checklist-32 (HCL-32) and the Temperament Evaluation of the Memphis, Pisa and San Diego-Autoquestionnaire (TEMPS-A). The role of temperamental traits in the relationship between morningness-eveningness and bipolarity was assessed using mediation analysis. Morningness is correlated with lower bipolarity measured by the MDQ and HCL-32, and to lower scores of depressive, cyclothymic, irritable and anxious temperaments of the TEMPS-A. There is no significant association between morningness and hyperthymic traits. Cyclothymic and irritable traits are full mediators of the association between chronotype and bipolarity, influencing bipolarity independently from circadian preferences. Depressive and anxious traits are partial mediators of this association, increasing the effect of eveningness on bipolarity. The indirectness of the findings in the web-based study and disproportion of participants' gender. Our study confirmed that eveningness is associated with bipolarity. In case of depressive and anxious temperaments, bipolarity is associated stronger with eveningness than with the TEMPS-A scores. On the other hand, cyclothymic and irritable temperaments were associated with bipolarity independently from circadian preferences. Copyright © 2018 Elsevier B.V. All rights reserved.

The aim of this study was to characterize at the population level how innate features of temperament relate to experience of depressive mood and anxiety, and whether these symptoms have separable temperamental backgrounds. The study subjects were 4773 members of the population-based Northern Finland Birth Cohort 1966, a culturally and genetically homogeneous study sample. Temperament was measured at age 31 using the temperament items of the Temperament and Character Inventory and a separate Pessimism score. Depressive mood was assessed based on a previous diagnosis of depressive disorder or symptoms of depression according to the Hopkins Symptom Check List - 25. Anxiety was assessed analogously. High levels of Harm avoidance and Pessimism were related to both depressive mood (effect sizes; d=0.84 and d=1.25, respectively) and depressive disorder (d=0.68 and d=0.68, respectively). Of the dimensions of Harm avoidance, Anticipatory worry and Fatigability had the strongest effects. Symptoms of depression and anxiety showed very similar underlying temperament patterns. Although Harm avoidance and Pessimism appear to be important endophenotype candidates for depression and anxiety, their potential usefulness as endophenotypes, and whether they meet all the suggested criteria for endophenotypes will remain to be confirmed in future studies. Personality characteristics of Pessimism and Harm avoidance, in particular its dimensions Anticipatory worry and Fatigability, are strongly related to symptoms of depression and anxiety as well as to depressive disorder in this population. These temperamental features may be used as dimensional susceptibility factors in etiological studies of depression, which may aid in the development of improved clinical practice.

Attention deficit hyperactivity disorder (ADHD) is theorized to have temperamental precursors early in life. These are difficult to identify because many core features of ADHD, such as breakdowns in executive function and self-control, involve psychological and neural systems that are too immature to reliably show dysfunction in early life. ADHD also involves emotional dysregulation, and these temperamental features appear earlier as well. Here, we report a first attempt to utilize indices of emotional regulation to identify ADHD-related liability in infancy. Fifty women were recruited in the 2nd trimester of pregnancy, with overselection for high parental ADHD symptoms. Measures of maternal body mass index, nutrition, substance use, stress, and mood were examined during pregnancy as potential confounds. Offspring were evaluated at 6 months of age using LABTAB procedures designed to elicit fear, anger, and regulatory behavior. Mothers completed the Infant Behavior Questionnaire about their child's temperament. After control for associated covariates, including maternal depression and prenatal stress, family history of ADHD was associated with measures of anger/irritability, including infant negative vocalizations during the arm restraint task (p = .004), and maternal ratings of infant distress to limitations (p = .036). In the regulation domain, familial ADHD was associated with less parent-oriented attention seeking during the still face procedure (p < .001), but this was not echoed in the maternal ratings of recovery from distress. Affective response at 6 months of age may identify infants with familial history of ADHD, providing an early indicator of ADHD liability. These preliminary results provide a foundation for further studies and will be amplified by enlarging this cohort and following participants longitudinally to evaluate ADHD outcomes. © 2015 Association for Child and Adolescent Mental Health.

The structure of temperament displays subaffective traits as attributes of adaptive value. There are few studies on how different professions compare on temperaments. Our aim was to examine the relationship between the choices of Portuguese students in their fields of study, and their respective temperaments. The sample included 1386 students from six different universities (law, engineering, arts, medicine, psychology, and nursing), of both genders (67% female), and ages between 17 and 58 (X + or - SD = 21 + or - 3.4). Law and art students presented a cyclothymic or irritable temperament. Engineering students presented a hyperthymic temperament. Psychology and nursing students presented predominantly depressive and anxious temperaments. Medicine students were least extreme in temperament scores or frequencies. Nursing students came largely from one university located in a Portuguese city (northeast from Lisbon) which could be a potential limitation to be confirmed. Distinct temperamental profiles of students enrolled in different professional fields could be identified in our sample taking into account the presence or absence of excessive temperaments. Future physicians did not present a predominant temperament, future lawyers and artists presented predominantly a cyclothymic or irritable temperament, future engineers presented a hyperthymic temperament and, future psychologists and nurses presented predominantly depressive and anxious temperaments.

2011-12-01

The stability of eating patterns from infancy through childhood is largely unknown. This study identified subgroups of children based on emergent eating patterns from ages 1 to 3 years and examined differences between groups in demographic, anthropometric and temperamental variables. We conducted secondary analyses of 262 boys and 225 girls from the Colorado Adoption Project. Three eating styles (Reactivity to Food, Predictable Appetite, Distractibility at Mealtime) and five temperaments were assessed at ages 1 and 3 years. Weight and height (length) were assessed on children and mothers. Correlations examined the stability of eating patterns, cluster analysis identified subgroups of emergent eating styles, and analysis of variance identified variables differentiating the derived subgroups. Eating styles were moderately stable over time, although all increased on average. Four subgroups were identified: Diet Expanding and Preference Establishing Eaters (37%), Emerging Reactive Tendency Eaters (23%), Emerging Food-Indifferent and Non-Fussy Eaters (31%), and Emerging High-Reactive and Fussy Eaters (9%). The subgroups differed in year 1 Wt/L and Reaction to Food, and year 1-to-3 changes in Emotionality and Reaction to Food. Four emergent eating patterns were identified. How these subgroups of children differ in later weight and health trajectories warrants research. Copyright © 2011 Elsevier Ltd. All rights reserved.

Temperamental precursors of infant attachment with mothers and fathers.

The degree to which parent sensitivity and infant temperament distinguish attachment classification was examined. Multilevel modeling was used to assess the effect of parent sensitivity and infant temperament on infant-mother and infant-father attachment. Data were collected from mothers, fathers, and their infants (N = 135) when the infant was 3-, 5-, 7-, 12-, and 14-months old. Temperament was measured using the Infant Behavior Questionnaire-Revised (Gartstein & Rothbart, 2003); parent sensitivity was coded during the Still Face Paradigm (Tronick, Als, Adamson, Wise, & Brazelton, 1978); attachment was coded using the Strange Situation (Ainsworth, Blehar, Waters, & Wall, 1978). Results indicate that mothers and fathers were less sensitive with insecure-avoidant infants. Whereas only one difference was found for infant-mother attachment groups and temperament, five significant differences emerged for infant-father attachment groups, with the majority involving insecure-ambivalent attachment. Infants classified as ambivalent with fathers were higher in perceptual sensitivity and cuddliness and these infants also showed a greater increase in low-intensity pleasure over time compared with other infants. Results indicate the importance of both parent sensitivity and infant temperament, though operating in somewhat different ways, in the development of the infant-mother and infant-father attachment relationship.

Even though obsessive-compulsive disorders (OCD) and anxiety disorders (AD) have been separated in the taxonomy adopted by the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders, many issues remain concerning the physiopathological similarities and differences between those categories. Our objective was therefore to explore and compare their personality and emotional features, with the assumption that the distinction of two independent spectrums should imply the existence of two partially distinct temperamental profiles. We used the Temperament and Character Inventory (TCI-R) and the Positive and Negative Emotionality (PNE) scale to compare two groups of patients with OCD (n=227) or AD (n=827). The latter group included patients with social anxiety disorder, panic disorder, agoraphobia, and generalized anxiety disorder. Most temperament, character and emotionality measures showed no significant differences between both groups. In the personality measures results, only the self-directedness score (TCI-R) was significantly lower in OCD patients but this difference was not significant when the comparison was adjusted for the depressive scale score and age. Only lower PNE positive affects scores were obtained in OCD patients in the adjusted comparisons. These findings suggest that OCD and AD are not really distinguishable from the point of view of associated personality traits. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Activity level in the lab: Overlap with shyness indicates it is more than pure motoric activity.

Frazier-Wood, Alexis C; Saudino, Kimberly J

2017-09-01

The observation that children's activity level (AL) differs between novel and familiar situations is well established. What influences individual differences in how AL is different across these situations is less well understood. Drawing on animal literature, which links rats' AL when 1st placed in a novel setting with novelty seeking phenotypes, and child temperament literature, which links AL, novelty response, and shyness, we hypothesized that shyness would be an important component of children's AL in a novel situation. We examined this using mechanically assessed AL from 2 situations (the home and the lab) and 2 measures of shyness (1 parent-rated and 1 observer-rated) on up to 313 twin pairs (145 monozygotic and 168 dizygotic), at 2 and 3 years of age. Biometric genetic models removed from lab AL the variance shared with home AL, representing what was different in AL when the child entered the lab compared to the home. We report that almost half (43%) of the genetic component of AL in the lab was independent of AL in the home, and this unique genetic component shared genetic covariance with shyness. Shyness influences AL in a novel situation such as the lab, indicating that mechanically assessed AL represents more than global motoric activity and provides information on a child's temperamental response to novelty.

Behavioral inhibition and anxiety: The moderating roles of inhibitory control and attention shifting

2013-01-01

Behavioral inhibition (BI), a temperament identified in early childhood, is associated with social reticence in childhood and an increased risk for anxiety problems in adolescence and adulthood. However, not all behaviorally inhibited children remain reticent or develop an anxiety disorder. One possible mechanism accounting for the variability in the developmental trajectories of BI is a child’s ability to successfully recruit cognitive processes involved in the regulation of negative reactivity. However, separate cognitive processes may differentially moderate the association between BI and later anxiety problems. The goal of the current study was to examine how two cognitive processes - attention shifting and inhibitory control - laboratory assessed at 48 months of age moderated the association between 24-month BI and anxiety symptoms in the preschool years. Results revealed that high levels of attention shifting decreased the risk for anxiety symptoms in children with high levels of BI, whereas high levels of inhibitory control increased this risk for anxiety symptoms. These findings suggest that different cognitive processes may influence relative levels of risk or adaptation depending upon a child’s temperamental reactivity. PMID:21301953

Three dimensions of temperament -- difficult temperament, unadaptablility and unsociability -- were assessed in the first year of life by maternal interview in twins born in Puerto Rico during 2001 and 2002. Eight hundred and sixty-five eligible mothers (80%) were traced and interviewed. Model-fitting results showed that additive genetic factors and the individual specific environment contributed to variation in all three dimensions. In addition, the pattern of variances and correlations suggested that sibling contrast effects influence ratings of difficult temperament. Moderate effects of the shared environment contributed to ratings of adaptability and sociability. There was a significant genetic correlation between difficult temperament and unadaptability. Genetic and environmental effects do not differ significantly between boys and girls. The study is the first population-based study of Puerto Rican twins and one of few to attempt the assessment of behavior in the first year. Preliminary results for difficult temperament and sociability were consistent with those in other populations and ages. In contrast, a significant effect of the shared environment on the temperamental trait of unadaptability has not been reported previously.

Respiratory Sinus Arrhythmia, Effortful Control, and Parenting as Predictors of Children’s Sympathy Across Early Childhood

2015-01-01

The goal of this study was to examine physiological and environmental predictors of children’s sympathy (an emotional response consisting of feelings of concern or sorrow for others who are distressed or in need) and whether temperamental effortful control mediated these relations. Specifically, in a study of 192 children (23% Hispanic; 54% male), respiratory sinus arrhythmia (RSA), a measure thought to reflect physiological regulation, and observed authoritative parenting (both at 42 months) were examined as predictors of children’s effortful control (at 54 months) and, in turn, children’s sympathy (at 72 and 84 months). Measures of both baseline RSA and RSA suppression were examined. In a structural equation model, observed parenting was positively related to children’s subsequent sympathy through its positive relation to effortful control. Furthermore, the indirect path from baseline RSA to higher sympathy through effortful control was marginally significant. Authoritative parenting and baseline RSA uniquely predicted individual differences in children’s effortful control. Findings highlight the potential role of both authoritative parenting and physiological regulation in the development of children’s sympathy. PMID:25329555

The goal of the current study was to examine how two cognitive processes-attention shifting and inhibitory control-laboratory assessed at 48 months of age moderated the association between 24-month BI and anxiety symptoms in the preschool years. Results revealed that high levels of attention shifting decreased the risk for anxiety problems in children with high levels of BI, whereas high levels of inhibitory control increased this risk for anxiety symptoms. These findings suggest that different cognitive processes may influence relative levels of risk or adaptation depending upon a child's temperamental reactivity.

The goal of this study was to examine physiological and environmental predictors of children's sympathy (an emotional response consisting of feelings of concern or sorrow for others who are distressed or in need) and whether temperamental effortful control mediated these relations. Specifically, in a study of 192 children (23% Hispanic; 54% male), respiratory sinus arrhythmia (RSA), a measure thought to reflect physiological regulation, and observed authoritative parenting (both at 42 months) were examined as predictors of children's effortful control (at 54 months) and, in turn, children's sympathy (at 72 and 84 months). Measures of both baseline RSA and RSA suppression were examined. In a structural equation model, observed parenting was positively related to children's subsequent sympathy through its positive relation to effortful control. Furthermore, the indirect path from baseline RSA to higher sympathy through effortful control was marginally significant. Authoritative parenting and baseline RSA uniquely predicted individual differences in children's effortful control. Findings highlight the potential role of both authoritative parenting and physiological regulation in the development of children's sympathy.

Emotional reactions involve changes in both cognitive and bodily processes. Therefore, effective emotion regulation may also involve modulation of responses in both of these systems. The present study investigated the relationship between regulation of cognition and regulation of the heart in children and adolescents, using a go/nogo task in combination with the induction of negative emotions. Behavioral, temperamental and event-related brain potential (ERP) indicators of inhibitory cognitive control were collected, as was a measure of parasympathetic control of the heart (respiratory sinus arrhythmia, RSA). Independently of age, RSA was correlated with nogo N2 magnitudes during the emotion-induction procedure. RSA during the task was also correlated with N2 latencies and with behavioral accuracy before, during and after the emotion induction. Resting RSA was correlated with individual differences in the capacity for effortful cognitive control, as measured by questionnaire. These results suggest that emotional responses in seemingly distinct neurophysiological systems may be regulated in an integrated fashion throughout the developmental span tested.

Temperament: a consideration of concepts and methods.

PubMed

Stevenson, J; Graham, P

1982-01-01

This paper discusses conceptual issues and begins with a consideration of definitions of temperament. It is suggested that the purposes for which temperament has been studied have, to some degree, dictated methods used and inferences drawn. Those psychopathologists interested in the relationship between temperament and psychiatric disorder, or emotional and behavioural disturbance, have tended to use different methods from those more concerned with delineating the structure of personality. Some issues and problems are common to both approaches, e.g. the definition of behaviour reflecting temperament in terms of style rather than content. Other issues, such as the difficulty involved in drawing a clear distinction between temperamental attributes and mental disorders, are restricted to one approach. The relative contribution of gentic and environmental effects is of interest to both psychopathologists (who wish to examine this issue in relation to the development of the individual), and to psychologists (who are usually more concerned with populations or aggregate effects). The application of biometric genetic models might clarify this issue, and various suggestions are made regarding steps that need to be taken if such models are to be successfully applied.

[Neurobiological aspects of reactive and proactive violence in antisocial personality disorder and "psychopathy"].

PubMed

Roth, Gerhard; Strüber, Daniel

2009-01-01

Impulsive-reactive violent offenders show increased autonomic activity in response to negative emotional and threatening stimuli. A volume reduction and/or activity decrease of frontal brain structures associated with impulse control and the regulation of fear and anger are likewise found in combination with a fear-related hyperactivity of the amygdala. In addition, impulsive aggression is facilitated by variants of gene polymorphisms influencing the serotonergic system. Conversely, proactive-instrumental violent offender with psychopathy, who are characterized by a lack of empathy and remorse, demonstrate an autonomic hypo-responsivity as well as dysfunctions of the amygdala and of cortical regions related to empathic and social behavior. Developmentally, aggressive children exhibit temperamental differences from early childhood on that are characteristic of a developmental pathway towards either reactive or proactive violence later in life. Exposure to negative environmental factors like ineffective parenting or childhood maltreatment has been related to a heightened risk for developing reactive violence. A developmental trajectory of proactive violence, however, has been related to a mostly genetically determined callous unemotional temperament of the child that disrupts the parental socialization efforts during childhood.

In beef cattle, feeding behaviour and activity are associated with feed efficiency and methane (CH4) emissions. This study aimed to understand the underlying traits responsible for the contribution of cattle behaviour to individual differences in feed efficiency, performance and CH4 emissions. A total of 84 steers (530±114 kg BW) of two different breeds (crossbreed Charolais and Luing) were used. The experiment was a 2×2×3 factorial design with breed, basal diets (concentrate v. mixed) and dietary treatments (no additive, calcium nitrate or rapeseed cake) as the main factors. The individual dry matter intake (DMI; kg) was recorded daily and the BW was measured weekly over a 56-day period. Ultrasound fat depth was measured on day 56. Based on the previous data, the indexes average daily gain, food conversion and residual feed intake (RFI) were calculated. The frequency of meals, the duration per visit and the time spent feeding per day were taken as feeding behaviour measures. Daily activity was measured using the number of steps, the number of standing bouts and the time standing per day. Agonistic interactions (including the number of contacts, aggressive interactions, and displacements per day) between steers at the feeders were assessed as indicators of dominance. Temperament was assessed using the crush score test (which measures restlessness when restrained) and the flight speed on release from restraint. Statistical analysis was performed using multivariate regression models. Steers that spent more time eating showed better feed efficiency (P=0.039), which can be due to greater secretion of saliva. Feeding time was longer with the mixed diet (P<0.001), Luings (P=0.009) and dominant steers (P=0.032). Higher activity (more steps) in the pen was associated with poorer RFI, possibly because of higher energy expenditure for muscle activity. Frequent meals contributed to a reduction in CH4 emissions per kg DMI. The meal frequency was higher with a mixed diet (P<0.001) and increased in more temperamental (P=0.003) and dominant (P=0.017) steers. In addition, feed intake was lower (P=0.032) in more temperamental steers. This study reveals that efficiency increases with a longer feeding time and CH4 emissions decrease with more frequent meals. As dominant steers eat more frequently and for longer, a reduction in competition at the feeder would improve both feed efficiency and CH4 emissions. Feed efficiency can also be improved through a reduction in activity. Selection for calmer cattle would reduce activity and increase feed intake, which may improve feed efficiency and promote growth, respectively.

A growing body of evidence highlights the relationship between epigenetics, especially DNA methylation, and population divergence as well as speciation. However, little is known about how general the phenomenon of epigenetics-wise separation of different populations is, or whether population assignment is, possible based on solely epigenetic marks. In the present study, we compared DNA methylation profiles between four different canine populations: three domestic dog breeds and their ancestor the gray wolf. Altogether, 79 CpG sites constituting the 65 so-called CpG units located in the promoter regions of genes affecting behavioral and temperamental traits (COMT, HTR1A, MAOA, OXTR, SLC6A4, TPH1, WFS1)-regions putatively targeted during domestication and breed selection. Methylation status of buccal cells was assessed using EpiTYPER technology. Significant inter-population methylation differences were found in 52.3% of all CpG units investigated. DNA methylation profile-based hierarchical cluster analysis indicated an unambiguous segregation of wolf from domestic dog. In addition, one of the three dog breeds (Golden Retriever) investigated also formed a separate, autonomous group. The findings support that population segregation is interrelated with shifts in DNA methylation patterns, at least in putative selection target regions, and also imply that epigenetic profiles could provide a sufficient basis for population assignment of individuals.

Temperament and parenting antecedents of individual differences in three-year-old boys' pride and shame reactions.

1997-06-01

To examine individual differences in pride and shame reactions of 3-year-olds and their temperamental and parenting antecedents, 110 boys were studied at ages 36 and 37 months in a "rigged" achievement situation. After being trained to complete explicitly stipulated "easy" and "difficult" tasks before a buzzer sounded, success and failure were manipulated by artificially "rigging" how much time the child had to work on these tasks. Children's facial, verbal, and postural reactions to success and failure were composited to create pride scores following success and shame scores following failure. As expected, pride reactions were greater following success on the difficult than on the easy task, and shame reactions were greater following failure on the easy than on the difficult task. Early temperament (at 12/13 months) proved unrelated to pride and shame. With respect to parenting, measurements composited across 15, 21, 27, and 33 months showed that mothers and fathers who were more positive in their parenting had children who displayed less pride, and that children whose parents (especially mothers) were more negative in their parenting evinced less shame. These counterintuitive findings are discussed in terms of differences between assessments of parenting obtained in this investigation of parenting antecedents and those obtained in other studies of parental responses in the achievement situation itself. Directions for future research are outlined.

Neural reactivity to monetary rewards and losses differentiates social from generalized anxiety in children.

The relationship between reward sensitivity and pediatric anxiety is poorly understood. Evidence suggests that alterations in reward processing are more characteristic of depressive than anxiety disorders. However, some studies have reported that anxiety disorders are also associated with perturbations in reward processing. Heterogeneity in the forms of anxiety studied may account for the differences between studies. We used the feedback-negativity, an event-related potential sensitive to monetary gains versus losses (ΔFN), to examine whether different forms of youth anxiety symptoms were uniquely associated with reward sensitivity as indexed by neural reactivity to the receipt of positive and negative monetary outcomes. Participants were 390, eight- to ten-year-old children (175 females) from a large community sample. The ΔFN was measured during a monetary reward task. Self-reports of child anxiety and depression symptoms and temperamental positive emotionality (PE) were obtained. Multiple regression analysis revealed that social anxiety and generalized anxiety symptoms were unique predictors of reward sensitivity after accounting for concurrent depressive symptoms and PE. While social anxiety was associated with a greater ΔFN, generalized anxiety was associated with a reduced ΔFN. Different symptom dimensions of child anxiety are differentially related to alterations in reward sensitivity. This may, in part, explain inconsistent findings in the literature regarding reward processing in anxiety. © 2014 Association for Child and Adolescent Mental Health.

The aim was to analyze the relationship between Cloninger's dimensions and Personality Disorders (PD) (with DSM-IV criteria) in opiate dependents. The study was Cross-sectional. The sampling of 196 patients with opiate dependence was consecutive. All were receiving treatment in an inpatient detoxification unit. Cloninger's Temperament and Character Inventory (TCI), International Personality Disorders Examination (IPDE) and a Substance Use Questionnaire were used. Character's dimensions as Self-directness and Cooperation were related with PD when scored low. Opposite to Cloninger descriptions, high scores of Self-transcendence were related with presence of PD. Related to temperamental dimensions, cluster A was related with low scores of Reward Dependence (RD) and cluster C with high scores of Harm Avoidance (HA). Otherwise, in cluster B, while Borderline PD had high scores of Novelty Seeking (as high HA), the Antisocial PD only were related to low scores of RD. RD dimension seems useful to differ from presence or absence of Antisocial PD, also when alcohol consumption is considered. Cloninger's Model of Personality is useful in drug dependents for the definition of the different PD, as well as for probable PD's aggregation. This model also helps to create subtypes in opiate dependents as the antisocial or type II.

A dark past, a restrained present, and an apocalyptic future: time perspective, personality, and life satisfaction among anorexia nervosa patients.

Despite reporting low levels of well-being, anorexia nervosa patients express temperament traits (e.g., extraversion and persistence) necessary for high levels of life satisfaction. Nevertheless, among individuals without eating disorders, a balanced organization of the flow of time, influences life satisfaction beyond temperamental dispositions. A balanced time perspective is defined as: high past positive, low past negative, high present hedonistic, low present fatalistic, and high future. We investigated differences in time perspective dimensions, personality traits, and life satisfaction between anorexia nervosa patients and matched controls. We also investigated if the personality traits and the outlook on time associated to positive levels of life satisfaction among controls also predicted anorexia patients' life satisfaction. Additionally, we investigated if time perspective dimensions predicted life satisfaction beyond personality traits among both patients and controls. A total of 88 anorexia nervosa patients from a clinic in the West of Sweden and 111 gender-age matched controls from a university in the West of Sweden participated in the Study. All participants responded to the Zimbardo Time Perspective Inventory, the Ten Item Personality Inventory, and the Temporal Satisfaction with Life Scale. A t -test showed that patients scored higher in the past negative, the present fatalistic, and the future dimensions, lower in the past positive and the present hedonistic dimensions, higher in conscientiousness, extraversion, and agreeableness, and lower in life satisfaction. Regression analyses showed that life satisfaction was predicted by openness to experience and emotional stability for controls and by emotional stability among patients. When time dimensions were entered in the regression, emotional stability and the past negative and past positive time dimensions predicted life satisfaction among controls, but only the past positive and present hedonistic time dimensions predicted life satisfaction among patients. Anorexia patients were less satisfied with life despite being more conscientious, social, and agreeable than controls. Moreover, compared to controls, patients had an unbalanced time perspective: a dark view of the past (i.e., high past negative), a restrained present (i.e., low present hedonistic) and an apocalyptic view of the future (i.e., high present fatalistic). It is plausible to suggest that, therapeutic interventions should focus on empowering patients to cultivate a sentimental and positive view of the past (i.e., high past positive) and the desire to experience pleasure without concern for future consequences (i.e., high present hedonistic) so that they can make self-directed and flexible choices for their own well-being. Such interventions might have effects on life satisfaction beyond the patients' temperamental disposition.

Individual differences in human temperament can increase risk for psychiatric disorders like depression and anxiety. Our laboratory utilized a rat model of temperamental differences to assess neurodevelopmental factors underlying emotional behavior differences. Rats selectively bred for low novelty exploration (Low Responders, LR) display high levels of anxiety- and depression-like behavior compared to High Novelty Responder (HR) rats. Using transcriptome profiling, the present study uncovered vast gene expression differences in the early postnatal HR versus LR limbic brain, including changes in genes involved in cellular metabolism. These data led us to hypothesize that rats prone to high (versus low) anxiety/depression-like behavior exhibit distinct patterns of brain metabolism during the first weeks of life, which may reflect disparate patterns of synaptogenesis and brain circuit development. Thus, in a second experiment we examined activity of Cytochrome C Oxidase (COX), an enzyme responsible for ATP production and a correlate of metabolic activity, to explore functional energetic differences in HR/LR early postnatal brain. We found that HR rats display higher COX activity in the amygdala and specific hippocampal subregions compared to LRs during the first 2 weeks of life. Correlational analysis examining COX levels across several brain regions and multiple early postnatal time points suggested desynchronization in the developmental timeline of the limbic HR versus LR brain during the first two postnatal weeks. These early divergent COX activity levels may reflect altered circuitry or synaptic activity in the early postnatal HR/LR brain, which could contribute to the emergence of their distinct behavioral phenotypes.

Genetic predisposition to high anxiety- and depression-like behavior coincides with diminished DNA methylation in the adult rat amygdala

Understanding biological mechanisms that shape vulnerability to emotional dysfunction is critical for elucidating the neurobiology of psychiatric illnesses like anxiety and depression. To elucidate molecular and epigenetic alterations in the brain that contribute to individual differences in emotionality, our laboratory utilized a rodent model of temperamental differences. Rats bred for low response to novelty (Low Responders, LRs) are inhibited in novel situations and display high anxiety, helplessness, and diminished sociability compared to High Novelty Responder (HR) rats. Our current transcriptome profiling experiment identified widespread gene expression differences in the amygdala of adult HR/LR rats; we hypothesize that HR/LR gene expression and downstream behavioral differences stem from distinct epigenetic (specifically DNA methylation) patterning in the HR/LR brain. Although we found similar levels of DNA methyltransferase proteins in the adult HR/LR amygdala, next-generation sequencing analysis of the methylome revealed 793 differentially methylated genomic sites between the groups. Most of the differentially methylated sites were hypermethylated in HR versus LR, so we next tested the hypothesis that enhancing DNA methylation in LRs would improve their anxiety/depression-like phenotype. We found that increasing DNA methylation in LRs (via increased dietary methyl donor content) improved their anxiety-like behavior and decreased their typically high levels of Forced Swim Test (FST) immobility; however, dietary methyl donor depletion exacerbated LRs’ high FST immobility. These data are generally consistent with findings in depressed patients showing that treatment with DNA methylation-promoting agents improves depressive symptoms, and highlight epigenetic mechanisms that may contribute to individual differences in risk for emotional dysfunction.

Abstract: Beyond both being biphasic/bidirectional disorders (hypo)mania and essential hypertension share a surprising number of similarities and an overlap between their genetics, biological background, underlying personality and temperamental factors, precipitating factors, comorbidity and response to treatment, indicating a possibly partially shared biological background. Based on theoretical knowledge, similarities related to characteristics, manifestation and course, and the results of pharmacological studies related to the effects and side effects of pharmacotherapies used in the treatment of these two distinct disorders, the authors outline a hypothesis discussing the similar origins of these two phenomena and thus mania being the hypertension of mood in memory of Athanasios Koukopoulos, one of the greatest researchers and theoreticists of mania of all time.

Given that depression is a debilitating disorder, it is critical that we advance our understanding about the aetiology of this disorder. This study investigated both traditional (temperament and parenting) and novel (emotion regulation strategy) risk factors associated with adolescent depression. Forty-four adolescents (12-16 years; 64% females) with high scores on a self-report depressive symptomatology questionnaire were compared to a similar group of 44 adolescents with low scores, matched for age, gender, and ethnicity. Significant group differences were present on all assessed risk factors. The presence of high depressive symptomatology was found to be associated with (1) low levels of temperamentally based positive mood, flexibility, and approach behaviours, (2) a parenting style characterized by low nurturance and high overprotection, and (3) emotion regulation characterized by higher levels of expressive suppression and lower levels of cognitive reappraisal. It was concluded that, in addition to specific temperament characteristics and parenting style, use of particular emotion regulation strategies is associated with varying levels of depressive symptomatology. These findings reinforce the importance of incorporating emotion regulation into explanatory models of depression symptomatology. Further research that tests the direction of effects for these cross-sectional findings is warranted.

Evaluating Callous-Unemotional Traits as a Personality Construct.

PubMed

Frick, Paul J; Ray, James V

2015-12-01

We evaluate the importance of callous-unemotional (CU) traits as a personality construct in isolation from other facets of psychopathy. Specifically, we review research suggesting that these traits are useful for designating a subgroup of youth with serious conduct problems who differ from other antisocial youth on important biological, emotional, cognitive, and social characteristics. In addition, the temperamental features related to CU traits are risk factors for impairments in conscience development in young children. Thus, these traits could advance theoretical models explaining the development of severe antisocial behavior and psychopathy. CU traits also have important clinical utility because they designate a particularly severe and impaired subgroup of antisocial youth, leading to their inclusion in the DSM-5. As a result of this inclusion in diagnostic classification, there has been an increased focus on how to best assess CU traits, and we discuss several key issues in their assessment, highlighting several limitations in existing measures. Finally, the increased use of CU traits, separately from other facets of psychopathy, makes it important to determine how these traits relate to other personality constructs. Thus, we examine how measures of CU traits relate to the broader construct of psychopathy and to other basic personality dimensions. © 2014 Wiley Periodicals, Inc.

Given the prevalence of Internet use among youth, there is concern that a subset of Internet-using youth may exhibit problematic or addictive patterns of Internet use. The present study examines the association between problematic Internet use (PIU), demographic variables, and health-related measures among Chinese adolescents. Survey data from 1552 adolescents (male = 653, mean age = 15.43 years) from Jilin Province, China, were collected. According to the Young Diagnostic Questionnaire for Internet Addiction (YDQ), 77.8% (n=1,207), 16.8% (n=260), and 5.5% (n=85) showed adaptive, maladaptive, and problematic Internet use, respectively. Multinomial logistic regression analysis revealed that gender and family income per month differed between youth showing problematic and adaptive patterns of Internet use. Well-being, self-esteem, and self-control were related to severity of problematic Internet use, with greater severity typically associated with poorer measures in each domain. The findings that severity of problematic Internet use is associated with specific socio-demographic features and temperamental and well-being measures suggest that specific groups of youth may be particularly vulnerable to developing problematic Internet use. Early prevention/intervention programs targeting at-risk groups may help improve public health. PMID:27249805

Regulatory difficulties are common in children with autism spectrum disorder. This study focused on an important aspect of self-regulation-the ability to willingly comply with frustrating demands of socialization agents, termed "self-regulated compliance." We studied compliance to parental demands in 40 preschoolers with autism spectrum disorder and 40 matched typically developing preschoolers, during separate interactions with mother and father, while engaging in two paradigms: toy pick-up and delayed gratification, which tap the "do" and "don't" aspects of self-regulated socialization at this age. Parents' disciplinary style was micro-coded from the two paradigms and child temperament was parent reported. Compared to their typically developing peers, children with autism spectrum disorder showed more noncompliance and less self-regulated compliance to parental demands and prohibitions and greater temperamental difficulties across several domains. No group differences were found in parental disciplinary style. Child self-regulated compliance was associated with parental supportive disciplinary style and with child attention focusing. Findings highlight the importance of parental supportive presence in structuring the development of socialization in children with autism spectrum disorder. Implications for parent-child emotion regulation interventions are discussed. © The Author(s) 2015.

The author investigates the clinical affinity between Klein and Winnicott (1935-46) asa way to historically situate Winnicott 's later criticism of Klein's 'temperamental' inability to understand the impact of the environment on the infant's development. By setting out Klein s theories at the time when Winnicott began supervision with her in 1935, a context is established for the analysis of an unpublished 1937 manuscript by Klein ('Notes on baby'). The author argues that this direct and extensive infant observation demonstrates Klein's sensitivity to the familial environment. While Winnicott as a paediatrician showed enthusiasm for Klein s ideas, he also demonstrated a difference of opinion in emphasising the maternal environment of provision after his wartime evacuation experiences with London children. The factors leading to their mutual distancing are outlined as follows: (1) the post-Controversial Discussion atmosphere of the British Psycho-Analytical Society in 1944. The new non-aligned psychoanalytic 'middle group' allowed Winnicott to take a pick and choose attitude towards available analytic theories; (2) Winnicott us new clinical practices and theory differed from Klein 's, leading to a widening gap between 1946 and 1951. Winnicott's new theory and practice simultaneously represented his technical marginalisation of Klein s emphasis on the direct analysis of the patient s destructiveness by the time he delivered the 'Transitional objects' paper in 1951.

Differences in Spontaneously Avoiding or Approaching Mice Reflect Differences in CB1-Mediated Signaling of Dorsal Striatal Transmission

Approach or avoidance behaviors are accompanied by perceptual vigilance for, affective reactivity to and behavioral predisposition towards rewarding or punitive stimuli, respectively. We detected three subpopulations of C57BL/6J mice that responded with avoiding, balancing or approaching behaviors not induced by any experimental manipulation but spontaneously displayed in an approach/avoidance conflict task. Although the detailed neuronal mechanisms underlying the balancing between approach and avoidance are not fully clarified, there is growing evidence that endocannabinoid system (ECS) plays a critical role in the control of these balancing actions. The sensitivity of dorsal striatal synapses to the activation of cannabinoid CB1 receptors was investigated in the subpopulations of spontaneously avoiding, balancing or approaching mice. Avoiding animals displayed decreased control of CB1 receptors on GABAergic striatal transmission and in parallel increase of behavioral inhibition. Conversely, approaching animals exhibited increased control of CB1 receptors and in parallel increase of explorative behavior. Balancing animals reacted with balanced responses between approach and avoidance patterns. Treating avoiding animals with URB597 (fatty acid amide hydrolase inhibitor) or approaching animals with AM251 (CB1 receptor inverse agonist) reverted their respective behavioral and electrophysiological patterns. Therefore, enhanced or reduced CB1-mediated control on dorsal striatal transmission represents the synaptic hallmark of the approach or avoidance behavior, respectively. Thus, the opposite spontaneous responses to conflicting stimuli are modulated by a different involvement of endocannabinoid signaling of dorsal striatal neurons in the range of temperamental traits related to individual differences.

2015-01-01

The stability of frontal electroencephalogram (EEG) asymmetry, temperamental activity level and fear, as well as bidirectional relations between asymmetry and temperament across the first four years of life were examined in a sample of 183 children. Children participated in annual lab visits through 48 months, providing EEG and maternal report of temperament. EEG asymmetry showed moderate stability between 10 and 24 months. Analyses revealed that more left asymmetry predicted later activity level across the first three years. Conversely, asymmetry did not predict fear. Rather, fear at 36 months predicted more right asymmetry at 48 months. Results highlight the need for additional longitudinal research of infants and children to increase understanding of bidirectional relations between EEG and temperament in typically developing populations.

The current study examined interactions among genetic influences and children's early environments on the development of externalizing behaviors from 18 months to 6 years of age. Participants included 233 families linked through adoption (birth parents and adoptive families). Genetic influences were assessed by birth parent temperamental regulation. Early environments included both family (overreactive parenting) and out-of-home factors (center-based Early Care and Education; ECE). Overreactive parenting predicted more child externalizing behaviors. Attending center-based ECE was associated with increasing externalizing behaviors only for children with genetic liability for dysregulation. Additionally, children who were at risk for externalizing behaviors due to both genetic variability and exposure to center-based ECE were more sensitive to the effects of overreactive parenting on externalizing behavior than other children.

Borderline Personality Disorder is a serious mental disease, classified in Cluster B of DSM IV-TR personality disorders. People with this syndrome presents an anamnesis of traumatic experiences and shows dissociative symptoms. Since not all subjects who have been victims of trauma develop a Borderline Personality Disorder, the emergence of this serious disease seems to have the fragility of character as a predisposing condition. Infect, numerous studies show that subjects positive for diagnosis of Borderline Personality Disorder had scores extremely high or extremely low to some temperamental dimensions (harm Avoidance and reward dependence) and character dimensions (cooperativeness and self directedness). In a sample of 602 subjects, who have had consecutive access to an Outpatient Mental Health Service, it was evaluated the presence of Borderline Personality Disorder using the semi-structured interview for the DSM IV-TR personality disorders. In this population we assessed the presence of dissociative symptoms with the Dissociative Experiences Scale and the personality traits with the Temperament and Character Inventory developed by Cloninger. To assess the weight and the predictive value of these psychopathological dimensions in relation to the Borderline Personality Disorder diagnosis, a neural network statistical model called "multilayer perceptron," was implemented. This model was developed with a dichotomous dependent variable, consisting in the presence or absence of the diagnosis of borderline personality disorder and with five covariates. The first one is the taxonomic subscale of dissociative experience scale, the others are temperamental and characterial traits: Novelty-Seeking, Harm-Avoidance, Self-Directedness and Cooperativeness. The statistical model, that results satisfactory, showed a significance capacity (89%) to predict the presence of borderline personality disorder. Furthermore, the dissociative symptoms seem to have a greater influence than the character traits in the borderline personality disorder e disease. In conclusion, the results seem to indicate that to borderline personality disorder development, contribute both psychic factors, such as temperament and character traits, and environmental factors, such as traumatic events capable of producing dissociative symptoms. These factors interact in a nonlinear way in producing maladaptive behaviors typical of this disorder.

Oral language is the foundation of literacy. Naturally, policies and practices to promote children's literacy begin in early childhood and have a strong focus on developing children's oral language, especially for children with known risk factors for low language ability. The underlying assumption is that children's progress along the oral to literate continuum is stable and predictable, such that low language ability foretells low literacy ability. This study investigated patterns and predictors of children's oral language and literacy abilities at 4, 6, 8 and 10 years. The study sample comprised 2,316 to 2,792 children from the first nationally representative Longitudinal Study of Australian Children (LSAC). Six developmental patterns were observed, a stable middle-high pattern, a stable low pattern, an improving pattern, a declining pattern, a fluctuating low pattern, and a fluctuating middle-high pattern. Most children (69%) fit a stable middle-high pattern. By contrast, less than 1% of children fit a stable low pattern. These results challenged the view that children's progress along the oral to literate continuum is stable and predictable. Multivariate logistic regression was used to investigate risks for low literacy ability at 10 years and sensitivity-specificity analysis was used to examine the predictive utility of the multivariate model. Predictors were modelled as risk variables with the lowest level of risk as the reference category. In the multivariate model, substantial risks for low literacy ability at 10 years, in order of descending magnitude, were: low school readiness, Aboriginal and/or Torres Strait Islander status and low language ability at 8 years. Moderate risks were high temperamental reactivity, low language ability at 4 years, and low language ability at 6 years. The following risk factors were not statistically significant in the multivariate model: Low maternal consistency, low family income, health care card, child not read to at home, maternal smoking, maternal education, family structure, temperamental persistence, and socio-economic area disadvantage. The results of the sensitivity-specificity analysis showed that a well-fitted multivariate model featuring risks of substantive magnitude did not do particularly well in predicting low literacy ability at 10 years.

A dark past, a restrained present, and an apocalyptic future: time perspective, personality, and life satisfaction among anorexia nervosa patients

Background Despite reporting low levels of well-being, anorexia nervosa patients express temperament traits (e.g., extraversion and persistence) necessary for high levels of life satisfaction. Nevertheless, among individuals without eating disorders, a balanced organization of the flow of time, influences life satisfaction beyond temperamental dispositions. A balanced time perspective is defined as: high past positive, low past negative, high present hedonistic, low present fatalistic, and high future. We investigated differences in time perspective dimensions, personality traits, and life satisfaction between anorexia nervosa patients and matched controls. We also investigated if the personality traits and the outlook on time associated to positive levels of life satisfaction among controls also predicted anorexia patients’ life satisfaction. Additionally, we investigated if time perspective dimensions predicted life satisfaction beyond personality traits among both patients and controls. Method A total of 88 anorexia nervosa patients from a clinic in the West of Sweden and 111 gender-age matched controls from a university in the West of Sweden participated in the Study. All participants responded to the Zimbardo Time Perspective Inventory, the Ten Item Personality Inventory, and the Temporal Satisfaction with Life Scale. Results A t-test showed that patients scored higher in the past negative, the present fatalistic, and the future dimensions, lower in the past positive and the present hedonistic dimensions, higher in conscientiousness, extraversion, and agreeableness, and lower in life satisfaction. Regression analyses showed that life satisfaction was predicted by openness to experience and emotional stability for controls and by emotional stability among patients. When time dimensions were entered in the regression, emotional stability and the past negative and past positive time dimensions predicted life satisfaction among controls, but only the past positive and present hedonistic time dimensions predicted life satisfaction among patients. Conclusion Anorexia patients were less satisfied with life despite being more conscientious, social, and agreeable than controls. Moreover, compared to controls, patients had an unbalanced time perspective: a dark view of the past (i.e., high past negative), a restrained present (i.e., low present hedonistic) and an apocalyptic view of the future (i.e., high present fatalistic). It is plausible to suggest that, therapeutic interventions should focus on empowering patients to cultivate a sentimental and positive view of the past (i.e., high past positive) and the desire to experience pleasure without concern for future consequences (i.e., high present hedonistic) so that they can make self-directed and flexible choices for their own well-being. Such interventions might have effects on life satisfaction beyond the patients’ temperamental disposition. PMID:28929023

Given the prevalence of Internet use among youth, there is concern that a subset of Internet-using youth may exhibit problematic or addictive patterns of Internet use. The present study examines the association between problematic Internet use (PIU), demographic variables, and health-related measures among Chinese adolescents. Survey data from 1552 adolescents (male=653, mean age=15.43years) from Jilin Province, China, were collected. According to the Young Diagnostic Questionnaire for Internet Addiction (YDQ), 77.8% (n=1207), 16.8% (n=260), and 5.5% (n=85) showed adaptive, maladaptive, and problematic Internet use, respectively. Multinomial logistic regression analysis revealed that gender and family income per month differed between youth showing problematic and adaptive patterns of Internet use. Well-being, self-esteem, and self-control were related to severity of problematic Internet use, with greater severity typically associated with poorer measures in each domain. The findings that severity of problematic Internet use is associated with specific socio-demographic features and temperamental and well-being measures suggest that specific groups of youth may be particularly vulnerable to developing problematic Internet use. Early prevention/intervention programs targeting at-risk groups may help improve public health. Copyright © 2016 Elsevier Ltd. All rights reserved.

Longitudinal Associations Between Temperament and Socioemotional Outcomes in Young Children: The Moderating Role of RSA and Gender

Temperament is an important predictor of socioemotional adjustment, such as externalizing and internalizing symptoms. However, there is not a one-to-one correspondence between temperamental predispositions and these outcomes, implying that other factors also contribute to the development of internalizing and externalizing problems. Self-regulation is believed to interact with temperament, and has been studied as a predictor for later socioemotional outcomes. Respiratory sinus arrhythmia (RSA) is a psychophysiological measure of self-regulation that has been studied as a moderator of risk. The primary aim of the present study was to test if RSA baseline and RSA reactivity would moderate the link between temperament and socioemotional outcomes. Mothers reported the temperament of their infants (20 months; N=154), RSA was collected at 24- and 42-months, and mothers reported externalizing and internalizing behaviors at kindergarten entry. RSA baseline and RSA reactivity moderated the relation between exuberant temperament and externalizing behaviors. However, these results were only significant for girls, such that high RSA baseline and greater RSA suppression predicted more externalizing behaviors when exuberance was high. Fearful temperament predicted later internalizing behaviors, but no moderation was present. These results are discussed in light of recent evidence regarding gender differences in the role of RSA as a protective factor for risk. PMID:25399505

Research on adults points to personality as a crucial determinant of well-being. The present study investigates the question of personality's relation to well-being and psychosocial adjustment in adolescence. We assessed the role of temperament and character (Temperament and Character Inventory, TCI-125), on psychological well-being (PWB; Psychological Well-Being scales), subjective well-being (SWB; Positive and Negative Affect, PA and NA, respectively), and psychosocial adjustment (emotional-behavioural problems measured by the Strengths and Difficulties Questionnaire for Adolescents, SDQ-A), in 72 Italian late adolescents (aged 17.5 ± 0.75). Multiple regressions were conducted to predict PWB, SWB, and SDQ-A scores using TCI-125 scales as predictors. Character maturity, and in particular Self-Directedness, had a widespread protective effect on well-being and psychosocial adjustment, while different strengths and emotional-behavioural difficulties were associated to specific temperamental and character traits. For example, Harm-Avoidance and Novelty-Seeking positively predicted internalized and externalized problems, respectively. The present results suggest the usefulness of continuing to evaluate temperament and, in particular, character dimensions in investigations focused on adolescents' well-being and psychosocial functioning, especially in the contexts of potential interventions aimed at enhancing development of adolescents' character dimensions at the intrapersonal, interpersonal, and transpersonal levels.

Frontal brain electrical activity (EEG) and heart rate in response to affective infant-directed (ID) speech in 9-month-old infants.

PubMed

Santesso, Diane L; Schmidt, Louis A; Trainor, Laurel J

2007-10-01

Many studies have shown that infants prefer infant-directed (ID) speech to adult-directed (AD) speech. ID speech functions to aid language learning, obtain and/or maintain an infant's attention, and create emotional communication between the infant and caregiver. We examined psychophysiological responses to ID speech that varied in affective content (i.e., love/comfort, surprise, fear) in a group of typically developing 9-month-old infants. Regional EEG and heart rate were collected continuously during stimulus presentation. We found the pattern of overall frontal EEG power was linearly related to affective intensity of the ID speech, such that EEG power was greatest in response to fear, than surprise than love/comfort; this linear pattern was specific to the frontal region. We also noted that heart rate decelerated to ID speech independent of affective content. As well, infants who were reported by their mothers as temperamentally distressed tended to exhibit greater relative right frontal EEG activity during baseline and in response to affective ID speech, consistent with previous work with visual stimuli and extending it to the auditory modality. Findings are discussed in terms of how increases in frontal EEG power in response to different affective intensity may reflect the cognitive aspects of emotional processing across sensory domains in infancy.

Cortical associates of emotional reactivity and regulation in childhood stuttering.

This study sought to determine the cortical associates of emotional reactivity and emotion regulation (as indexed by the amplitude of evoked response potentials [ERP]) in young children who do and do not stutter during passive viewing of pleasant, unpleasant and neutral pictures. Participants were 17 young children who stutter and 22 young children who do not stutter (between 4 years 0 months to 6 years 11 months). The dependent measures were (1) mean amplitude of late positive potential (LPP, an ERP sensitive to emotional stimuli) during passive (i.e., no response required) picture viewing and directed reappraisal tasks and (2) emotional reactivity and regulation related scores on caregiver reports of young children's temperament (Children's Behavior Questionnaire, CBQ). Young CWS, when compared to CWNS, exhibited significantly greater LPP amplitudes when viewing unpleasant pictures, but no significant between-group difference when viewing pleasant pictures and during the emotion regulation condition. There were, however, for CWS, but not CWNS, significant correlations between temperament-related measures of emotion and cortical measures of emotional reactivity and regulation. Findings provide further empirical support for the notion that emotional processes are associated with childhood stuttering, and that CWS's inherent temperamental proclivities need to be taken into account when empirically studying or theorizing about this association.

In this study, bullying is examined in light of the “prosocial security hypothesis”— i.e., the hypothesis that insecure attachment, with temperamental dispositions such as sensation seeking, may foster individualistic, competitive value orientations and problem behaviors. A group of 375 Italian students (53% female; Mean age = 12.58, SD = 1.08) completed anonymous questionnaires regarding attachment security, social values, sensation seeking, and bullying behaviors. Path analysis showed that attachment to mother was negatively associated with bullying of others, both directly and through the mediating role of conservative socially oriented values, while attachment to father was directly associated with victimization. Sensation seeking predicted bullying of others and victimization both directly and through the mediating role of conservative socially oriented values. Adolescents’ gender affected how attachment moderated the relationship between sensation seeking and problem behavior. PMID:29535668

A cybernetic model of global personality traits.

PubMed

Van Egeren, Lawrence F

2009-05-01

Neurobehavioral studies of human and animal temperament have shed light on how individual personality traits influence human actions. This approach, however, leaves open questions about how the entire system of traits and temperaments function together to exercise control. To address this key issue, I describe a cybernetic model of control and then apply it to the Big Five (B5) personality traits. Employing evidence from descriptive trait terms, temperamental behavioral processes associated with traits, and empirical correlates of traits, I relate distinct cybernetic processes of self-regulation to the B5 traits. The B5 traits broadly parallel basic cybernetic self-regulation processes. For example, the core behavior activation property of the B5 Extraversion trait can be mapped onto the device output function of automated cybernetic control systems. Implications and limitations of interpreting personality traits in self-regulation terms are discussed.

Evidence supports the role of temperament in the origins of psychiatric disorders. However, there are few data on associations between temperament and psychiatric disorders in early childhood. A community sample of 541 three-year old preschoolers participated in a laboratory temperament assessment, and caregivers were administered a structured diagnostic interview on preschool psychopathology. In bivariate analyses, temperamental dysphoria and low exuberance were associated with depression; fear, low exuberance, and low sociability were associated with anxiety disorders; and disinhibition and dysphoria were associated with oppositional defiant disorder. Although there were no bivariate associations between temperament and attention-deficit/hyperactivity disorder, disinhibition emerged as a unique predictor in multivariate analyses. Findings indicate that the pattern of relations between temperament and psychopathology in older youth and adults is evident as early as age 3. PMID:21391025

Children who exhibit elevated levels of the temperament trait behavioural inhibition (BI) across time may be at greatest risk for anxiety. However, little research has investigated the influence of other temperamental traits, particularly positive emotionality (PE), on the continuity of BI in childhood, nor whether parental overprotection influences associations between early and later child BI. To explore whether PE and overprotection shape associations between early and later BI, this longitudinal study of three-year-olds (N = 446) followed up at age 6 included tasks tapping child temperament, and parental overprotection was assessed via interview ratings and parent-report. Lower levels of child PE and higher levels of caregiver overprotection at baseline predicted stronger associations between laboratory-assessed BI at ages 3 and 6. Findings elucidate influences shaping the developmental continuity of BI. PMID:27765998

This study examined genetic and environmental influences on harsh parenting of adopted 9-month-olds (N = 503), with an emphasis on positive child-, parent-, and family-level characteristics. Evocative gene-environment correlation (rGE) was examined by testing the effect of both positive and negative indices of birth parent temperament on adoptive parents' harsh parenting. Adoptive fathers' harsh parenting was inversely related to birth mother positive temperament, indicating evocative rGE, as well as to marital quality. Adoptive parents' negative temperamental characteristics were related to hostile parenting for both fathers and mothers. Findings support the importance of enhancing positive family characteristics in addition to mitigating negative characteristics, as well as engaging multiple levels of the family system to prevent harsh parenting. © 2015 The Authors.

Refractory Depressed and Anxious States in Hyperthymic Women: A Case Series Generated by a Speaking Engagement

Manning, J. Sloan

2000-01-01

The author discusses 4 referrals that were the direct result of a case description from his own practice that he presented during a lecture on the treatment of mixed anxious and depressive illness in primary care. The cases depict energetic, productive women who suffer fatigue and episodic depressions. These cases suggest that hyperthymic temperaments complicated by depressive episodes represent a form of mood disorder presentation that is highly recognizable and responsive to pharmacologic intervention. Such premorbid temperamental hypomanic tendencies may represent a soft form of bipolar illness that requires somatic strategies in line with those of classic manic depressive illness. The cases underscore the challenge of treating mood disorders and the need for treatment research to reach primary care practitioners, who see the majority of depressed and anxious patients.

Despite high rates of grandmother involvement with young grandchildren, very little research has examined the associations between non-residential grandmother involvement and grandchild social adjustment. The present study draws 127 families enrolled in the Family Transitions Project to consider the degree to which mother-reported maternal grandmother involvement buffers 3- and 4-year old grandchildren from economic, parenting, and child temperamental risks for reduced social competence and elevated externalizing behaviors. Findings indicate that higher levels of mother-reported grandmother involvement reduced the negative association between observed grandchild negative emotional reactivity and social competence. Further, high levels of mother-reported grandmother involvement protected grandchildren from the positive association between observed harsh mother parenting and grandchild externalizing behaviors. These findings underscore the relevance of moving beyond the nuclear family to understand factors linked to social adjustment during early childhood. PMID:20954774

Toward a definition of affective instability.

PubMed

Renaud, Suzane M; Zacchia, Camillo

2012-01-01

Affective instability is a psychophysiological symptom observed in some psychopathologies. It is a complex construct that encompasses (1) primary emotions, or affects, and secondary emotions, with each category having its own characteristics, amplitude, and duration, (2) rapid shifting from neutral or valenced affect to intense affect, and (3) dysfunctional modulation of emotions. Affective instability is often confused with mood lability, as in bipolar disorders, as well as with other terms. To clarify the concept, we searched databases for the term affective instability and read related articles on the topic. In this article we situate the term within the current affective nomenclature and human emotional experience, explore its psychophysiological features, and place it within the context of psychopathology. We explain why the term can potentially be confused with mood pathology and then define affective instability as an inherited temperamental trait modulated by developmental experience.

Nonstandard maternal work schedules during infancy: Implications for children's early behavior problems

Daniel, Stephanie S.; Grzywacz, Joseph G.; Leerkes, Esther; Tucker, Jenna; Han, Wen-Jui

2009-01-01

This paper examines the associations between maternal nonstandard work schedules during infancy and children's early behavior problems, and the extent to which infant temperament may moderate these associations. Hypothesized associations were tested using data from the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care (Phase I). Analyses focused on mothers who returned to work by the time the child was 6 months of age, and who worked an average of at least 35 h per week from 6 through 36 months. At 24 and 36 months, children whose mothers worked a nonstandard schedule had higher internalizing and externalizing behaviors. Modest, albeit inconsistent, evidence suggests that temperamentally reactive children may be more vulnerable to maternal work schedules. Maternal depressive symptoms partially mediated associations between nonstandard maternal work schedules and child behavior outcomes. PMID:19233479

2016-04-01

The sensation/novelty seeking behavioral trait refers to the exploration/preference for a novel environment. Novelty seeking increases during late adolescence and it has been associated with several neurobehavioral disorders. In this experiment, we asked whether inbred Roman high- and low-avoidance (RHA-I, RLA-I) rats (1) differ in novelty seeking in late adolescence and (2) whether late adolescent novelty seeking predicts this trait in adulthood. Thirty six male RHA-I and 36 RLA-I rats were exposed to a novel object exploration (NOE) test during late adolescence (pnd: 52-59; contact latency, contact time, contact frequency). Head-dipping (hole-board, HB), time and visits to a novel-arm (Y-maze), and latency-in and emergence latency (emergence test) were registered in adulthood (pnd: 83-105). The results showed strain differences in all these tests (RHA-I>RLA-I). Factor analysis (RHA-I+RLA-I) revealed two clusters. The first one grouped HB and emergence test measures. The second one grouped NOE and Y-maze variables. Time exploring a novel object (NOE) was a significant predictor of novel arm time (RHA-I+RLA, RHA-I); contact latency was a significant predictor of novel arm frequency (RLA-I). Present results show consistent behavioral associations across four novelty-seeking tests and suggest that late adolescent novelty seeking predicts this genetically-influenced temperamental trait in adult Roman rats.

State Variability and Psychopathological Attractors: the Behavioural Complexity as Discriminating Factor Between the Pathology and Normality Profiles

NASA Astrophysics Data System (ADS)

Marconi, Pier Luigi

369 patients, selected within a set of 1215 outpatients, were studied. The data were clustered into two set: the baseline set and the endpoint set. The clinical parameters had a higher variability at the baseline than at the endpoint. 4 to 5 factors were extracted in total group and 3 subgroups (190 "affective", 34 type-B personality, 166 without any of both disorders). In all subgroups there was a background pattern of 6 components: 3 components confirming the trifactorial temperamental model of Cloninger; 1 component related to the quality of social relationships; 2 components (that are the main components of factorial model about in all groups) relating to quality of life and adjustment self perceived by patients, and to pattern of dysfunctional behavior, inner feelings, and thought processes externally evaluated. These background components seem to aggregate differently in the subgroups in accordance to the clinical diagnosis. These patterns may be interpreted as expression of an increased "coherence" among parameters due to a lack of flexibility caused by the illness. The different class of illness can be further distinguished by intensity of maladjustment, that is related to the intensity of clinical signs just only at the baseline. These data suggest that the main interfering factors are clinical psychopathology at baseline and stable personality traits at endpoint. This persistent chronic maladjustment personality-driven is evidenced after the clinical disorder was cured by treatment. An interpretative model is presented by the author.

The aim of this study was to identify predictors of completed suicide in a wide sample of psychiatric inpatients receiving retrospective and prospective DSM-IV diagnoses. We followed up 4441 severe psychiatric patients who were hospitalized for some time during a 35-year period in a private hospital setting. We collected sociodemographic, clinical and temperamental data. Ninety-six patients from the sample committed suicide. There were no sex differences in suicide completion and no differences between major psychiatric disorders, but people who had been hospitalized for anxiety disorders did not commit suicide and people with bipolar disorders were more likely to commit suicide than people with unipolar major depression. Shorter-term treatment with lithium and anticonvulsants, longer-term treatment with antidepressants, history of suicide attempts, suicidal thinking, and single status positively predicted completed suicide. Suicide tended to occur after a mean period of about 14 years of duration of disease. Patients' symptoms during the period preceding suicide were assessed through interviewing patients' physicians or family members. Symptoms occurring in >10% of cases were, in decreasing order, inner tension, racing/crowded thoughts, aggressive behavior, guilt, psychomotor agitation, persecutory ideation, anxiety, and hallucinations. Surprisingly, cyclothymic temperament was less associated with completed suicide as compared to other temperaments. Suicide is likely to occur in a milieu of agitation, mixed anxiety and depression, and psychosis. Longer-term mood stabilizer treatment may reduce the rate of completed suicide. © 2011 The Authors.

Although perfectionism has long been established as an important risk factor for depressive mood and eating disorders, the mechanisms through which this temperamental predisposition mediates the relationship between depressive mood and eating disorder symptoms are still relatively unclear. In this study we hypothesized that both perfectionism dimensions, self-oriented perfectionism and socially prescribed perfectionism, would mediate the relationship between current symptoms of depression and eating disorders in a non-clinical sample of Spanish undergraduate females. Two hundred sixteen female undergraduate students of the University Complutense of Madrid (Spain) completed the Spanish versions of the Eating Attitudes Test (EAT-40), the Multidimensional Perfectionism Scale (MPS), OBQ-44, and BDI-II and BAI. Results demonstrated the importance of socially prescribed perfectionism in mediation of the relationship between depressive mood and symptoms of eating disorders. Socially prescribed perfectionism mediates the relationship between depressive mood and eating disorder symptoms for female college students.

The aim of this study was to evaluate possible interactions between childhood trauma, temperament, character, and psychopathology among alcohol-dependent men. Participants were 156 alcohol-dependent men consecutively admitted to a dependency treatment unit. The Childhood Abuse and Neglect Questionnaire, the Temperament and Character Inventory, and the Symptom Checklist-Revised were administered to all participants. Childhood abuse and neglect did not have any effect on temperament and character scores in multivariate analysis. Whereas childhood abuse had a significant main effect on all types of clinical psychopathology except depression and psychoticism scores, childhood neglect only had a significant main effect on depression scores. There was no interaction between childhood abuse and neglect on these analyses. Among alcohol-dependent men, childhood abuse and neglect contribute to general psychopathology through distinct clinical consequences, independently of temperamental and characterological features.

In this special issue dedicated to Falret and the French contributions to the concept of cyclicity in manic depressive illness, we begin with a historical overview of the development of the concept of cyclicity and its fundamental significance in manic-depressive illness and we underscore how the concept fell into neglect only to reemerge in recent years. We then look at the intimate relationship between mania and depression. The hypothesis of the primacy of mania is discussed. The thesis is presented, supported by the examination of 100 consecutive index manias, that in most cases mania is triggered by external factors acting upon hyperthymic patients, determining an exogenous cyclicity. On the other hand, in BPII patients the temperamental mood instability (cyclothymia) is an inherent and decisive factor in determining the cyclic autonomous course of the disorder. Finally, a new distinction of Bipolar Disorders, based on premorbid temperament and course of the illness, is considered.

Until the end of the nineties last century personality disorders could not be diagnosed before the age of eighteen. Nevertheless, the results of studies published in the last decade have revealed that personality disorders can be observed in children and adolescents and that personality disorders diagnosed in adult patients had been present as early as in childhood. The knowledge of possible mechanisms shaping personality disorders in childhood is unsatisfactory and needs to be expanded. Developmental psychology explains the development of abnormal personality through inappropriate attachment patterns and abnormal transitions between developmental phases. Genetic and temperamental factors are also important in the aetiology of personality disorders as well as early maladaptive schemas resulting from personal experiences and interactions with others. The aim of this article is to review the current knowledge on the mechanisms shaping the development of personality and personality disorders in childhood and adolescence.

This study examined links between inhibitory control, moral emotions (sympathy and guilt), and reparative behavior in an ethnically diverse sample of 4- and 8-year-olds (N = 162). Caregivers reported their children's reparative behavior, inhibitory control, and moral emotions through a questionnaire, and children reported their guilt feelings in response to a series of vignettes depicting moral transgressions. A hypothesized meditation model was tested with inhibitory control relating to reparative behavior through sympathy and guilt. In support of this model, results revealed that high levels of inhibitory control were associated with high levels of reparative behavior through high levels of sympathy and guilt. However, the mediation of inhibitory control to reparation through guilt was significant for 4-year-olds only. Results are discussed in relation to the temperamental, regulatory, and affective-moral precursors of reparative behavior in early and middle childhood.

Fifty-two children without significant sleep disturbance seen at a primary care clinic for well-child care were compared on measures of temperament, parenting style, daytime behavior, and overall sleep disturbance to three diagnostic subgroups identified in a pediatric sleep clinic: children with obstructive sleep apnea (n = 33), parasomnias (night terrors, sleepwalking, etc.) (n = 16), and behavioral sleep disorders (limit-setting disorder, etc.) (n = 31). The mean age of the entire sample was 5.7 years. Temperamental emotionality in the behavioral sleep disorders group was associated with a higher level of sleep disturbance (p < .001); parenting laxness was associated with sleep disturbance in the general pediatric population (p < .01); and intense and negative temperament characteristics seemed to be associated with clinically significant behavioral sleep disturbances. Ineffective parenting styles and daytime disruptive behaviors were more likely to be associated with the milder sleep disturbances found in children in a primary care setting.

Purpose This study sought to characterize temperament traits in a sample of children with autism spectrum disorder (ASD), ages 3–7 years old, and to determine the potential association between temperament and sensory features in ASD. Individual differences in sensory processing may form the basis for aspects of temperament and personality, and aberrations in sensory processing may inform why some temperamental traits are characteristic of specific clinical populations. Methods Nine dimensions of temperament from the Behavioral Style Questionnaire (McDevitt & Carey, 1996) were compared among groups of children with ASD (n = 54), developmentally delayed (DD; n = 33), and the original normative sample of typically developing children (Carey & McDevitt, 1978; n = 350) using an ANOVA to determine the extent to which groups differed in their temperament profiles. The hypothesized overlap between three dimensional constructs of sensory features (hyperresponsiveness, hyporesponsivness, and seeking) and the nine dimensions of temperament was analyzed in children with ASD using regression analyses. Results The ASD group displayed temperament scores distinct from norms for typically developing children on most dimensions of temperament (activity, rhythmicity, adaptability, approach, distractibility, intensity, persistence, and threshold) but differed from the DD group on only two dimensions (approach and distractibility). Analyses of associations between sensory constructs and temperament dimensions found that sensory hyporesponsiveness was associated with slowness to adapt, low reactivity, and low distractibility; a combination of increased sensory features (across all three patterns) was associated with increased withdrawal and more negative mood. Conclusions Although most dimensions of temperament distinguished children with ASD as a group, not all dimensions appear equally associated with sensory response patterns. Shared mechanisms underlying sensory responsiveness, temperament, and social withdrawal may be fruitful to explore in future studies. PMID:22366913

Aims Oral language is the foundation of literacy. Naturally, policies and practices to promote children’s literacy begin in early childhood and have a strong focus on developing children’s oral language, especially for children with known risk factors for low language ability. The underlying assumption is that children’s progress along the oral to literate continuum is stable and predictable, such that low language ability foretells low literacy ability. This study investigated patterns and predictors of children’s oral language and literacy abilities at 4, 6, 8 and 10 years. The study sample comprised 2,316 to 2,792 children from the first nationally representative Longitudinal Study of Australian Children (LSAC). Six developmental patterns were observed, a stable middle-high pattern, a stable low pattern, an improving pattern, a declining pattern, a fluctuating low pattern, and a fluctuating middle-high pattern. Most children (69%) fit a stable middle-high pattern. By contrast, less than 1% of children fit a stable low pattern. These results challenged the view that children’s progress along the oral to literate continuum is stable and predictable. Findings Multivariate logistic regression was used to investigate risks for low literacy ability at 10 years and sensitivity-specificity analysis was used to examine the predictive utility of the multivariate model. Predictors were modelled as risk variables with the lowest level of risk as the reference category. In the multivariate model, substantial risks for low literacy ability at 10 years, in order of descending magnitude, were: low school readiness, Aboriginal and/or Torres Strait Islander status and low language ability at 8 years. Moderate risks were high temperamental reactivity, low language ability at 4 years, and low language ability at 6 years. The following risk factors were not statistically significant in the multivariate model: Low maternal consistency, low family income, health care card, child not read to at home, maternal smoking, maternal education, family structure, temperamental persistence, and socio-economic area disadvantage. The results of the sensitivity-specificity analysis showed that a well-fitted multivariate model featuring risks of substantive magnitude did not do particularly well in predicting low literacy ability at 10 years.

Objective Panic disorder (PD) is frequently comorbid with insomnia, which could exacerbate panic symptoms and contribute to PD relapse. Research has suggested that characteristics are implicated in both PD and insomnia. However, there are no reports examining whether temperament and character affect insomnia in PD. Thus, we examined the relationship between insomnia and personality characteristics in PD patients. Methods Participants were 101 patients, recruited from 6 university hospitals in Korea, who met the DSM-IV-TR criteria for PD. We assessed sleep outcomes using the sleep items of 17-item Hamilton Depression Rating Scale (HAMD-17)(item 4=onset latency, item 5=middle awakening, and item 6=early awakening) and used the Cloninger's Temperament and Character Inventory-Revised-Short to assess personality characteristics. To examine the relationship between personality and insomnia, we used analysis of variance with age, sex, and severity of depression (total HAMD scores minus sum of the three sleep items) as the covariates. Results There were no statistical differences (p>0.1) in demographic and clinical data between patients with and without insomnia. Initial insomnia (delayed sleep onset) correlated to a high score on the temperamental dimension of novelty seeking 3 (NS3)(F1,96=6.93, p=0.03). There were no statistical differences (p>0.1) in NS3 between patients with and without middle or terminal insomnia. Conclusion The present study suggests that higher NS3 is related to the development of initial insomnia in PD and that temperament and character should be considered when assessing sleep problems in PD patients.

The variance in the range of personality trait expression appears to be linked to structural variance in specific brain regions. In evidencing associations between personality factors and neurobiological measures, it seems evident that the cerebellum has not been up to now thought as having a key role in personality. This paper will review the most recent structural and functional neuroimaging literature that engages the cerebellum in personality traits, as novelty seeking and harm avoidance, and it will discuss the findings in the context of contemporary theories of affective and cognitive cerebellar function. By using region of interest (ROI)- and voxel-based approaches, we recently evidenced that the cerebellar volumes correlate positively with novelty seeking scores and negatively with harm avoidance scores. Subjects who search for new situations as a novelty seeker does (and a harm avoiding does not do) show a different engagement of their cerebellar circuitries in order to rapidly adapt to changing environments. The emerging model of cerebellar functionality may explain how the cerebellar abilities in planning, controlling, and putting into action the behavior are associated to normal or abnormal personality constructs. In this framework, it is worth reporting that increased cerebellar volumes are even associated with high scores in alexithymia, construct of personality characterized by impairment in cognitive, emotional, and affective processing. On such a basis, it seems necessary to go over the traditional cortico-centric view of personality constructs and to address the function of the cerebellar system in sustaining aspects of motivational network that characterizes the different temperamental traits.

This work describes the rational bases justifying the use of acute tryptophan depletion technique in eating disorders (ED) and the methods and design used in our studies. Tryptophan depletion technique has been described and used in previous studies safely and makes it possible to evaluate the brain serotonin activity. Therefore it is used in the investigation of hypotheses on serotonergic deficiency in eating disorders. Furthermore, and given the relationship of the dysfunctions of serotonin activity with impulsive symptoms, the technique may be useful in biological differentiation of different subtypes, that is restrictive and bulimic, of ED. 57 female patients with DSM-IV eating disorders and 20 female controls were investigated with the tryptophan depletion test. A tryptophan-free amino acid solution was administered orally after a two-day low tryptophan diet to patients and controls. Free plasma tryptophan was measured at two and five hours following administration of the drink. Eating and emotional responses were measured with specific scales for five hours following the depletion. A study of the basic characteristics of the personality and impulsivity traits was also done. Relationship of the response to the test with the different clinical subtypes and with the temperamental and impulsive characteristics of the patients was studied. The test was effective in considerably reducing plasma tryptophan in five hours from baseline levels (76%) in the global sample. The test was well tolerated and no severe adverse effects were reported. Two patients withdrew from the test due to gastric intolerance. The tryptophan depletion test could be of value to study involvement of serotonin deficits in the symptomatology and pathophysiology of eating disorders.

Background Problematic Internet use (PIU) is an emerging entity with varied contents. Behavioral addictions have high comorbidity of attention deficit hyperactivity disorder and obsessive-compulsive spectrum disorders. Social networking site (SNS) addiction and role playing game (RPG) addiction are traditionally studied as separate entities. We present a case with excessive Internet use, with a particular focus on phenomenology and psychiatric comorbidities. Case presentation Fifteen-year-old girl with childhood onset attention deficit disorder, obsessive-compulsive disorder, adolescent onset trichotillomania, and disturbed family environment presented with excessive Facebook use. Main online activity was creating profiles in names of mainstream fictional characters and assuming their identity (background, linguistic attributes, etc.). This was a group activity with significant socialization in the virtual world. Craving, salience, withdrawal, mood modification, and conflict were clearly elucidated and significant social and occupational dysfunction was evident. Discussion This case highlights various vulnerability and sociofamilial factors contributing to behavioral addiction. It also highlights the presence of untreated comorbidities in such cases. The difference from contemporary RPGs and uniqueness of role playing on SNS is discussed. SNS role playing as a separate genre of PIU and its potential to reach epidemic proportions are discussed. Conclusions Individuals with temperamental vulnerability are likely to develop behavioral addictions. Identification and management of comorbid conditions are important. The content of PIU continues to evolve and needs further study.

A few personality traits are characteristic of pathologic gamblers (PGs), but it is not clear if and how their personality profile differs from that of non-pathologic gamblers (non-PGs). Sixty-five non-clinical subjects, differentiated into non-PGs and PGs with the means of the South Oak Gambling Screen (SOGS) and Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition-Text Revision (DSM-IV-TR) criteria, were administered with the Temperament and Character Inventory; their values were compared with those of control subjects (CS). Novelty seeking (NS) and self-transcendence (ST) values were higher whereas self-directedness and cooperativeness values were lower in PGs with respect to both non-PGs and CS. A positive correlation was noted between SOGS score and NS (r = 0.40) and ST (r = 0.50) values, as well as a significant positive dependence between SOGS score and a family history of gambling (t = 2.816; P = .007). The subsamples of PGs reporting a parental involvement in gambling showed higher NS than the remaining PGs. Specific temperamental and character dimensions, especially NS and ST, differentiated PGs from both non-PGs and CS; the identification of a personality profile at risk for problem gambling may represent an important predictor of outcome and constitute a possible target for specific treatment approaches.

The main objective of this study was to investigate the comorbid disorders and temperamental profiles of full syndrome and subthreshold attention-deficit/hyperactivity disorder (ADHD). A sample of 2,493 students was randomly selected from six representative elementary schools in Seoul, Korea. Among 245 children with full syndrome and subthreshold ADHD diagnosed by the diagnostic interview schedule for children-4th version, parents of 185 subjects (mean age 9.0 +/- 1.7 years) and of a random sample of 185 age- and gender-matched non-ADHD children have completed the parent's version of the children behavior checklist (CBCL) and the juvenile temperament and character inventory (JTCI). The prevalence rates of full syndrome and subthreshold ADHD were, respectively, 5.90% (95% confidence interval = 4.74-7.06) and 9.00% (95% confidence interval = 7.58-10.41). Subthreshold ADHD cases did not differ from full syndrome ADHD in any JTCI profile, showing high novelty seeking/low persistence/low self-directedness than controls. Subthreshold ADHD also showed increased risk for externalizing disorders and higher scores in eight CBCL scales (somatic complaints, anxious/depressed, social problems, attention problems, delinquent behaviors, aggressive behaviors, externalizing problems and total behavioral problems) compared to the controls. These results support the clinical relevance of subthreshold ADHD in Asian culture. Increased clinical awareness for children with subthreshold ADHD is needed.

In this study, we investigate the affective temperamental characteristics in a sample of ED (eating disorder) patients. 49 ED patients diagnosed by the SCID (Structured Clinical Interview for DSM-IV), were divided into two groups on the basis of the presence or absence of Binge Eating (restricting-anorexia nervosa [R-AN]= 16; Binge Eaters= 33). All patients were administered the TEMPS-I (Temperament Evaluation Memphis Pisa Semistructured - Interview), to assess affective temperament. A third group of controls (N= 1010), derived from a study with the TEMPS-I on normal subjects, was included for comparison. A full affective temperament was not found in patients of the restricting group. By contrast 24% of the binge eating group had a full affective temperament of one of three types. Comparing the three temperaments for the three groups, only cyclothymic temperament proved to be significant, with higher levels in the binge eating group (p<0.01). In this study, people with R-AN do not show a full affective temperament. However, people with binge eating, had depressive and hyperthymic temperament, and displayed higher level of cyclothymic temperament than the normal population. The findings of this study add to a growing literature on temperament in people with ED; particularly, they add to the view that may be various paths leading to R-AN, and these may differ from those of binge eating.

Biological Sensitivity to Context Moderates the Effects of the Early Teacher-Child Relationship on the Development of Mental Health by Adolescence

The moderating effects of biological sensitivity to context (physiological and behavioral stress reactivity) on the association between the early teacher-child relationship and the development of adolescent mental health problems were examined in a community sample of 96 children. Grade 1 measures of biological sensitivity to context included physiological (i.e., slope of mean arterial pressure across a 20-30 min stress protocol) and behavioral (i.e., temperamental inhibition/disinhibition) markers. Grade 1 measures of the teacher-child relationship included positive (i.e., closeness) and negative (i.e., conflict) qualities. Mental health symptoms were assessed at Grades 1 and 7. Results of a multiple regression analysis indicated substantial association of the teacher-child relationship with the development of adolescent mental health symptoms, especially for more reactive children. In addition to teacher-child relationship main effects, all four reactivity × teacher-child relationship interaction terms were statistically significant when controlling for Grade 1 symptom severity, suggesting that both physiological and behavioral reactivity moderate the association of both adverse and supportive aspects of the teacher-child relationship with Grade 7 symptom severity over and above Grade 1 severity. There were important differences depending on which stress reactivity measure was considered. The importance of these findings for recent theoretical arguments regarding biological sensitivity to context and differential susceptibility is discussed. PMID:21262045

Behavioral inhibition (BI) is a temperament characterized by social reticence and withdrawal from unfamiliar or novel contexts and conveys risk for social anxiety disorder. Developmental outcomes associated with this temperament can be influenced by children's caregiving context. The convergence of a child's temperamental disposition and rearing environment is ultimately expressed at both the behavioral and neural levels in emotional and cognitive response patterns to social challenges. The present study used functional neuroimaging to assess the moderating effects of different parenting styles on neural response to peer rejection in two groups of adolescents characterized by their early childhood temperament (M(age) = 17.89 years, N = 39, 17 males, 22 females; 18 with BI; 21 without BI). The moderating effects of authoritarian and authoritative parenting styles were examined in three brain regions linked with social anxiety: ventrolateral prefrontal cortex (vlPFC), striatum, and amygdala. In youth characterized with BI in childhood, but not in those without BI, diminished responses to peer rejection in vlPFC were associated with higher levels of authoritarian parenting. In contrast, all youth showed decreased caudate response to peer rejection at higher levels of authoritative parenting. These findings indicate that BI in early life relates to greater neurobiological sensitivity to variance in parenting styles, particularly harsh parenting, in late adolescence. These results are discussed in relation to biopsychosocial models of development.

This study capitalizes on developmental data from an Australian population-based birth cohort to identify developmental markers of abnormal eating attitudes and behaviors in adolescence. The aims were twofold: (1) to develop a comprehensive path model identifying infant and childhood developmental correlates of Abnormal Eating Attitudes and Behaviors in adolescence, and (2) to explore potential gender differences. Data were drawn from a 30-year longitudinal study that has followed the health and development of a population based cohort across 15 waves of data collection from infancy since 1983: The Australian Temperament Project. Participants in this analysis were the 1,300 youth who completed the 11th survey at 15-16 years (1998) and who completed the eating disorder inventory at this time point. Developmental correlates of Abnormal Eating Attitudes and Behaviors in mid-adolescence were temperamental persistence, early gestational age, persistent high weight, teen depression, stronger peer relationships, maternal dieting behavior, and pubertal timing. Overall, these factors accounted for 28% of the variance in Abnormal Eating Attitudes and Behaviors at 15-16 years of age. Depressive symptoms, maternal dieting behavior, and early puberty were more important factors for girls. Late puberty was a more important factor for boys. Findings address an important gap in our understanding of the etiology of Abnormal Eating Attitudes and Behaviors in adolescence and suggest multiple targets for preventive intervention. © 2014 Wiley Periodicals, Inc.

Emotion dysregulation (ED) has long been recognized in clinical descriptions of attention-deficit hyperactivity disorder (ADHD), but a renewed interest in ED has advanced research on the overlap between the two entities. Autonomic reactivity (AR) is a neurobiological correlate of emotion regulation; however, the association between ADHD and AR remains unclear. Our aim was to explore the clinical differences, AR, and subjective emotional responses to visual emotional stimuli in ADHD children with and without ED. School-aged ADHD children with (n = 28) and without (n = 20) ED, according to the definition of deficiency in emotional self-regulation (DESR), and healthy controls (n = 22) were interviewed by using the Schedule for Affective Disorders and Schizophrenia for School Aged Children-Present and Lifetime version (K-SADS-PL) to screen frequent psychopathologies for these ages. All subjects were evaluated with Child Behavior Checklist 6-18 (CBCL), the Strengths and Difficulties Questionnaire (SDQ), the McMaster Family Assessment Device (FAD), the School-Age Temperament Inventory (SATI), and Conners' Parent Rating Scale (CPRS-48), which were completed by parents. To evaluate emotional responses, the International Affective Picture System (IAPS) and the subjective and physiological responses (electrodermal activity and heart rate reactivity) to selected pictures were examined. Regarding clinically distinctive features, the ADHD+ED group differed from the ADHD-ED and the control groups in terms of having higher temperamental negative reactivity, more oppositional/conduct problems, and lower prosocial behaviors. In the AR measures, children in the ADHD+ED group rated unpleasant stimuli as more negative, but they still had lower heart rate reactivity (HRR) than the ADHD-ED and control groups; moreover, unlike the two other groups, the ADHD+ED group showed no differences in HRR between different emotional stimuli. The presented findings are unique in terms of their ability to clinically and physiologically differentiate between ADHD children with and without ED.

Repeated Activation of a CS-US-Contingency Memory Results in Sustained Conditioned Responding

Individuals seem to differ in conditionability, i.e., the ease by which the contingent presentation of two stimuli will lead to a conditioned response. In contemporary learning theory, individual differences in the etiology and maintenance of anxiety disorders are, among others, explained by individual differences in temperamental variables (Mineka and Zinbarg, 2006). One such individual difference variable is how people process a learning experience when the conditioning stimuli are no longer present. Repeatedly thinking about the conditioning experience, as in worry or rumination, might prolong the initial (fear) reactions and as such, might leave certain individuals more vulnerable to developing an anxiety disorder. However, in human conditioning research, relatively little attention has been devoted to the processing of a memory trace after its initial acquisition, despite its potential influences on subsequent performance. Post-acquisition processing can be induced by mental reiteration of a conditioned stimulus-unconditioned stimulus (CS-US)-contingency. Using a human conditioned suppression paradigm, we investigated the effect of repeated activations of a CS-US-contingency memory on the level of conditioned responding at a later test. Results of three experiments showed more sustained responding to a “rehearsed” CS+ as compared to a “non-rehearsed” CS+. Moreover, the second experiment showed no effect of rehearsal when only the CS was rehearsed instead of the CS-US-contingency. The third experiment demonstrated that mental CS-US-rehearsal has the same effect regardless of whether it was cued by the CS and a verbal reference to the US or by a neutral signal, making the rehearsal “purely mental.” In sum, it was demonstrated that post-acquisition activation of a CS-US-contingency memory can impact conditioned responding, underlining the importance of post-acquisition processes in conditioning. This might indicate that individuals who are more prone to mentally rehearse information condition more easily. PMID:23755034

Repeated Activation of a CS-US-Contingency Memory Results in Sustained Conditioned Responding.

Individuals seem to differ in conditionability, i.e., the ease by which the contingent presentation of two stimuli will lead to a conditioned response. In contemporary learning theory, individual differences in the etiology and maintenance of anxiety disorders are, among others, explained by individual differences in temperamental variables (Mineka and Zinbarg, 2006). One such individual difference variable is how people process a learning experience when the conditioning stimuli are no longer present. Repeatedly thinking about the conditioning experience, as in worry or rumination, might prolong the initial (fear) reactions and as such, might leave certain individuals more vulnerable to developing an anxiety disorder. However, in human conditioning research, relatively little attention has been devoted to the processing of a memory trace after its initial acquisition, despite its potential influences on subsequent performance. Post-acquisition processing can be induced by mental reiteration of a conditioned stimulus-unconditioned stimulus (CS-US)-contingency. Using a human conditioned suppression paradigm, we investigated the effect of repeated activations of a CS-US-contingency memory on the level of conditioned responding at a later test. Results of three experiments showed more sustained responding to a "rehearsed" CS+ as compared to a "non-rehearsed" CS+. Moreover, the second experiment showed no effect of rehearsal when only the CS was rehearsed instead of the CS-US-contingency. The third experiment demonstrated that mental CS-US-rehearsal has the same effect regardless of whether it was cued by the CS and a verbal reference to the US or by a neutral signal, making the rehearsal "purely mental." In sum, it was demonstrated that post-acquisition activation of a CS-US-contingency memory can impact conditioned responding, underlining the importance of post-acquisition processes in conditioning.

Kerner Auch Koerner, Julia; Gust, Nicole; Petermann, Franz

2017-07-14

The dual pathway model of Attention Deficit Hyperactivity Disorder (ADHD) suggests that effortful control and positive approach, or surgency, are independent pathways leading to ADHD. This model has been proven on the basis of temperament in school children, however not in preschool children. In this study we tested whether the dual pathway model of ADHD can be replicated in preschool children using temperamental measures. One hundred and nineteen children (59 girls, M-age = 4.97 years, SD = 0.96) participated in a study. Parents rated temperament on the Child Behavior Questionnaire (CBQ) and parents and teachers rated ADHD symptoms (SDQ). We found that effortful control and surgency independently predicted preschool ADHD symptoms but there were no moderations or mediations. Our findings support the dual pathway model of temperament but not compensatory models of ADHD. Ratings of temperament might be an important predictor of which child is at risk to develop clinical ADHD later on and therefore an important part of prevention.

The effects of prenatal cocaine use on infant development.

Richardson, Gale A; Goldschmidt, Lidush; Willford, Jennifer

2008-01-01

This study examined the effect of prenatal cocaine use on infant physical, cognitive, and motor development, and temperamental characteristics, controlling for other factors that affect infant development. Women were, on average, 26.8 years old, had 12 years of education, and 46% were African American. During the first trimester, 18% were frequent users of cocaine (> or =1 line/day). The infants were, on average, 14.6 months old at this follow-up phase. Women who used cocaine during pregnancy rated their infants as more fussy/difficult and unadaptable than did women who did not use cocaine. Cocaine use in the second trimester was associated with significantly lower motor scores on the Bayley Scales of Infant Development (BSID) [N. Bayley, Manual for the Bayley Scales of Infant Development, Psychological Corporation, New York, 1969.]. There was no effect of prenatal cocaine use on BSID mental performance or on growth. These findings are consistent with other reports in the literature and with the hypothesis that prenatal cocaine exposure affects development through changes in neurotransmitter systems.

There are studies on the relationship between the position and shape of hair whorls on bovine forehead and phenotypic traits. According to anecdotal beliefs by horse users and handlers, temperamental traits may be related to the position of hair whorls in horses. No previous research on the mechanisms of inheritance of hair whorls has been performed, so the aim of the present study was to determine the heritability of the position of the hair whorl on the forehead of Konik horses. The horses (n = 362) were classified into five groups based on the whorl position on forehead with respect to the top and bottom eye lines. The estimated heritability of hair whorl position was 0.753 (SE = 0.056). Heritability adjusted for the discontinuity of the trait was 0.836. The results show that hair whorl position in Konik Polski horses is highly heritable. The possible relationship between position of hair whorls on the forehead and other morphological traits needs further research and should be interpreted with caution.

Suffering in silence: why a developmental psychopathology perspective on selective mutism is needed.

PubMed

Cohan, Sharon L; Price, Joseph M; Stein, Murray B

2006-08-01

A developmental psychopathology perspective is offered in an effort to organize the existing literature regarding the etiology of selective mutism (SM), a relatively rare disorder in which a child consistently fails to speak in 1 or more social settings (e.g., school) despite speaking normally in other settings (e.g., home). Following a brief description of the history, prevalence, and course of the disorder, multiple pathways to the development of SM are discussed, with a focus on the various genetic, temperamental, psychological, and social/environmental systems that may be important in conceptualizing this unusual childhood disorder. The authors propose that SM develops due to a series of complex interactions among the various systems reviewed (e.g., a strong genetic loading for anxiety interacts with an existing communication disorder, resulting in heightened sensitivity to verbal interactions and mutism in some settings). Suggestions are provided for future longitudinal, twin/adoption, molecular genetic, and neuroimaging studies that would be particularly helpful in testing the pathways perspective on SM.

Emotion Socialization Strategies of Mothers With Borderline Personality Disorder Symptoms: The Role of Maternal Emotion Regulation and Interactions With Infant Temperament.

2017-06-01

Although the interpersonal difficulties associated with borderline personality disorder (BPD) are well established, their manifestations within the context of parent-child relationships remain understudied. The current study investigated the relation of maternal BPD symptoms to nonsupportive emotion socialization (i.e., the extent to which mothers punish or minimize their young children's displays of negative emotions), as well as the mediating role of maternal emotion regulation difficulties in this relation. The authors also investigated the moderating role of maternal BPD symptoms in the relation between infant temperamental anger and fear and punitive/minimizing emotion socialization. Using a sample of 99 mother-infant dyads, the authors found that maternal BPD symptoms were significantly related to punitive/minimizing emotion socialization and that maternal emotion regulation difficulties mediated this relation. Moreover, maternal BPD symptoms strengthened the association between mother-reported infant anger and punitive/minimizing emotion socialization. These results extend the growing literature on the impact of maternal BPD on child development.

2012-01-01

Self-report data from 112 two-parent families were used to compare levels and predictors of four types of mothers’ and fathers’ engagement with their preschool aged children: socialization, didactic, caregiving, and physical play. Mothers were more involved than fathers in socialization, didactic, and caregiving, whereas fathers were more involved than mothers in physical play. Mothers’ greatest engagement was in caregiving, whereas fathers were about equally engaged in didactic, caregiving, and physical play. Mothers who contributed more to family income were less engaged in socialization and caregiving, whereas fathers with nontraditional beliefs about their roles were more engaged in didactic and caregiving. Children with greater temperamental effortful control received more didactic and physical play engagement from mothers. Fathers were more likely to engage in socialization activities with earlier-born children, whereas mothers were more likely to engage in socialization with girls high in effortful control. Mothers were more likely to engage in physical play with boys and with later-born children. PMID:23645966

Associations among Context-Specific Maternal Protective Behavior, Toddler Fearful Temperament, and Maternal Accuracy and Goals

Kiel, Elizabeth J.; Buss, Kristin A.

2011-01-01

Maternal protective responses to temperamentally fearful toddlers have previously been found to relate to increased risk for children’s development of anxiety-spectrum problems. Not all protective behavior is “overprotective,” and not all mothers respond to toddlers’ fear with protection. Therefore, the current study aimed to identify conditions under which an association between fearful temperament and protective maternal behavior occurs. Participants included 117 toddlers and their mothers, who were observed in a variety of laboratory tasks. Mothers predicted their toddlers’ fear reactions in these tasks and reported the importance of parent-centered goals for their children’s shyness. Protective behavior displayed in low-threat, but not high-threat, contexts related to concurrently observed fearful temperament and to mother-reported shy/inhibited behavior one year later. The relation between fearful temperament and protective behavior in low-threat, but not high-threat, contexts was strengthened by maternal accuracy in anticipating children’s fear and maternal parent-centered goals for children’s shyness.

Interest in mindfulness has increased over the last decade, resulting in several mindfulness-based interventions being developed and their efficacy empirically demonstrated. The practice of mindfulness has been associated with low levels of anxiety or depression and improved quality of life or personal well-being. The aim of this study is to translate the Child and Adolescent Mindfulness Measure (CAMM) and adapt it to Catalan so as to analyze its internal consistency and construct and convergent validity. The CAMM was administered to a sample of secondary school students ranging in age from 11 to 16 years old. The Catalan version of the CAMM shows a good fit with the unidimensional model and internal consistency similar to the original version (α = .80). Furthermore, CAMM scores correlated positively with subjective well-being, temperamental dimensions of effortful control and self-esteem. The Catalan Version of CAMM is a valid and reliable measure of mindfulness skills.

The Interaction Between Child Behavioral Inhibition and Parenting Behaviors: Effects on Internalizing and Externalizing Symptomology.

PubMed

Ryan, Sarah M; Ollendick, Thomas H

2018-02-20

Both child temperament and parenting have been extensively researched as predictors of child outcomes. However, theoretical models suggest that specific combinations of temperament styles and parenting behaviors are better predictors of certain child outcomes such as internalizing and externalizing symptoms than either temperament or parenting alone. The current qualitative review examines the interaction between one childhood temperamental characteristic (child behavioral inhibition) and parenting behaviors, and their subsequent impact on child psychopathology. Specifically, the moderating role of parenting on the relationship between child behavioral inhibition and both internalizing and externalizing psychopathology is examined, and the methodological variations which may contribute to inconsistent findings are explored. Additionally, support for the bidirectional relations between behavioral inhibition and parenting behaviors, as well as for the moderating role of temperament on the relationships between parenting and child outcomes, is briefly discussed. Finally, the clinical applicability of this overall conceptual model, specifically in regard to future research directions and potential clinical interventions, is considered.

Early family context and development of adolescent ruminative style: moderation by temperament.

PubMed

Hilt, Lori M; Armstrong, Jeffrey M; Essex, Marilyn J

2012-01-01

We know very little about the development of rumination, the tendency to passively brood about negative feelings. Because rumination is a risk factor for many forms of psychopathology, especially depression, such knowledge could prove important for preventing negative mental health outcomes in youth. This study examined developmental origins of rumination in a longitudinal sample (N=337; 51% girls) studied in preschool (ages 3½ and 4½ years) and early adolescence (ages 13 and 15 years). Results indicated that family context and child temperament, assessed during the preschool period, were risk factors for a ruminative style in adolescence. Specifically, early family contexts characterised by over-controlling parenting and a family style of negative-submissive expressivity predicted higher levels of later rumination. These associations were moderated by children's temperamental characteristics of negative affect and effortful control. Further, the interaction of these temperament factors exerted an additional influence on later rumination. Implications for prevention and intervention efforts are discussed.

Regulatory competence and social communication in term and preterm infants at 12 months corrected age. Results from a randomized controlled trial.

Temperamental regulatory competence and social communication in term and preterm infants at 12 months corrected age was studied in a randomized controlled intervention trial aimed at enhancing maternal sensitive responsiveness. Surviving infants <2000 g from a geographically defined area were randomized to an intervention (71) or a control group (69), and compared with term infants (74). The intervention was a modified version of the "Mother-Infant Transaction Program". Regulatory competence was measured with the Infant Behavior Questionnaire, and social communication with the Early Social Communication Scales. Preterm intervention infants with low regulatory competence had higher responding to joint attention than preterm control infants. A sensitizing intervention may moderate the association between temperament and social communication, and thus allow an alternative functional outlet for preterm infants low in regulatory competence. The finding may have implications for conceptualizations of the role of early sensitizing interventions in promoting important developmental outcomes for premature infants.

This study examined genetic and environmental influences on harsh parenting of 9-month-olds. We examined whether positive child-, parent-, and family-level characteristics were associated with harsh parenting in addition to negative characteristics. We were particularly interested in examining evocative gene-environment correlation (rGE) by testing the effect of birth parent temperament on adoptive parents’ harsh parenting. Additionally, we examined associations among adoptive parents’ own temperaments, their marital relationship quality, and harsh parenting. Adoptive fathers’ (but not adoptive mothers’) harsh parenting was inversely related to an index of birth mother positive temperament (reward dependence), indicating evocative rGE. Higher marital quality was associated with less harsh parenting, but only for adoptive fathers. Adoptive parents’ negative temperamental characteristics (harm avoidance) were related to hostile parenting. Findings suggest the importance of enhancing positive family characteristics in addition to mitigating negative characteristics, as well as engaging multiple levels of the family system to prevent harsh parenting.

Research has examined temperament in individuals with borderline personality disorder (BPD) but not in their offspring, despite offspring's risk of developing BPD and the importance of temperament in the etiology of BPD. We recruited a low-socioeconomic sample of 36 mothers with BPD and their children ages 4 through 7, and 34 normative comparisons. Replicating prior studies, mothers with BPD reported themselves as having more negative affectivity (frustration, fear) and less effortful control (inhibitory control, attentional control, activation control) than did comparisons. Mothers with BPD also reported that their offspring had more negative affectivity (anger/frustration, fear) and less effortful control (inhibitory control, attentional focusing) than did comparisons. We were concerned about potential bias and shared method variance. We therefore provided validity support for mothers' ratings of their children with teacher ratings of child behavior and child self-report via their story-stem completion narratives. We discuss children's temperamental vulnerability versus differential susceptibility to the environment.

The Role of Negative Affect and Physiological Regulation in maternal attribution

Wang, Zhe; Deater-Deckard, Kirby; Bell, Martha Ann

2016-01-01

SYNOPSIS Objective Mothers who attribute child misbehaviors to children’s intentions, and not to situational causes, show more hostile parenting behaviors. Why are some mothers more likely than others to make more hostile attributions (i.e., high intentional attributions and low situational attributions) when confronted with child challenging behaviors? We examined the relation between mothers’ perception of child challenging behaviors and their hostile attributions of child misbehaviors, with an emphasis on how maternal negative affect and resting vagal activity moderated this relation. Design 160 mothers of 3- to 7-year-old children reported their perceptions of child problem behaviors, their attributions regarding child misbehaviors, and their temperamental negative affect. Mothers’ respiratory sinus arrhythmia (RSA) was measured during resting state. Results Maternal perceptions of child challenging behaviors were positively related to hostile maternal attributions, and this relation was strongest in mothers with high negative affect and low resting RSA. Conclusions These findings indicate the importance of considering mothers’ affective and physiological attributes when examining social-cognitive processes in parenting. PMID:27667969

Background Depression is a broad and heterogeneous diagnostic grouping, central to which is depressed mood or inability to enjoy most activities. Depressive symptoms are frequently accompanied by conduct problems stemming from anger. It is very important to know the interrelation of these emotions very well to be able to help adolescents to manage them more easily. The main aim of this article is to present the problem of interaction between negative affects (emotional instability, anger state and trait, physical and verbal aggression and depression) analyzing the different relationship through the time in spanish sample. Material and Methods The sample included 470 adolescents (192 boys and 225 girls) in a three-wave longitudinal study in Valencia (Spain). The mean age was 14.70 in the first wave. Structural equations modelling was employed to explore two longitudinal models. Results The results show differences based on sex, and that an internalised variable, like emotional instability, is relevant to prevent the appearance of depression directly in girls and also the later appearance of aggression as long as anger mediates, in both boys and girls, so the control of anger becomes an important goal to control the rest of the negative affects. Conclusions This results has consequences in the preparation of all programmes that try to establish an emotional control on adolescents, as not only has to be taken into account as a direct goal the control of externalised emotions like anger, but internalised emotions like emotional instability have to be taken into account also. Furthermore, it is also made apparent that not only the punctual explosions and externalisation of anger have to be worked on, but the temperamental aspects which are the base of anger trait have to be worked on too. Key words:Emotional instability, anger, depression, aggression, negative emotions, adolescence. PMID:27545395

We compared sex-stratified developmental and temperamental profiles at 18 months in children screening negative for autism spectrum disorder (ASD) on the Modified Checklist for Autism in Toddlers (M-CHAT) but later receiving diagnoses of ASD (false-negative group) versus those without later ASD diagnoses (true-negative group). We included 68 197 screen-negative cases from the Norwegian Mother and Child Cohort Study (49.1% girls). Children were screened by using the 6 critical items of the M-CHAT at 18 months. Groups were compared on domains of the Ages and Stages Questionnaire and the Emotionality Activity Sociability Temperament Survey. Despite passing M-CHAT screening at 18 months, children in the false-negative group exhibited delays in social, communication, and motor skills compared with the true-negative group. Differences were more pronounced in girls. However, with regard to shyness, boys in the false-negative group were rated as more shy than their true-negative counterparts, but girls in the false-negative group were rated as less shy than their counterparts in the true-negative group. This is the first study to reveal that children who pass M-CHAT screening at 18 months and are later diagnosed with ASD exhibit delays in core social and communication areas as well as fine motor skills at 18 months. Differences appeared to be more pronounced in girls. With these findings, we underscore the need to enhance the understanding of early markers of ASD in boys and girls, as well as factors affecting parental report on early delays and abnormalities, to improve the sensitivity of screening instruments.

The Temperament Evaluation of the Memphis, Pisa, Paris and San Diego Questionnaire (TEMPS) has, in its self and rater-wise evaluation form, been designed to evaluate temperamental characteristics in clinical and non-clinical populations. In this study we aim to extend the field of correlations of TEMPS to include the Occupational Personality Questionnaire, ipsative version (OPQ32i). These correlations, if present, could provide a partial contribute to the validation process of TEMPS, currently in progress in various countries. OPQ32 is a self-report personality questionnaire designed to give information on an individual's preferred behavior, as assessed in terms of a number of work-related characteristics. In 921 applicants, who were competing to become cadets in the Italian Navy, we assessed, during the entrance examination, the correlations between TEMPS-A[P] and OPQ32i. Depressive temperament implies a low level of ability to relate to others; hyperthymic temperament implies high levels of feelings and emotions, and the capability to relate to people; cyclothymic temperament appears to be distinguished by creativity and a low level of relationships with others; irritable temperament partly overlaps with cyclothymic temperament, the main difference being the higher level of energy and the lower level of empathy of irritable subjects. The four affective temperaments, in our sample, proved to significantly differ in the work capacity features measured by OPQ32 factors. These observed correlations between the two tests partially contributes to the ongoing validation process of TEMPS-A[P]. From a personality standpoint this study further supports the hypothesis that temperaments belong to the realm of normality rather than that of pathology, in line with their putative adaptive role.

Alcohol use, "alcohol abuse," and illicit drug use were investigated in a representative sample of 1076 urban, northern Italian high school students aged 14 to 19 years in 2001. In addition to questions on substance use, the participants were asked about school achievements and perceived substance use among friends. All the students were submitted to Zuckerman Sensation Seeking Scale (SSS) scale, Eysenck Personality Questionnaire (EPQ), Buss-Durkee Hostility Inventory (BDHI), and Parental Bonding Instrument (PBI). Lifetime alcohol use was found in 80.5%, "alcohol abuse" in 37.7%, cannabis use in 26.2%, ecstasy in 2.8%, heroin in 3.8%, and cocaine in 8.3% of the students: gender differences were significant for alcohol use, "alcohol abuse" and ecstasy use, with male subjects outnumbering females, but not for reported cannabis, heroin, and cocaine use. Early substance use onset among adolescents aged 14-16 years was detected. Higher sensation seeking on SSS, social coping impairment on EPQ, direct aggressiveness on BDHI, poor school achievements, and lower parental care on PBI were found associated with illicit drug use and "alcohol abuse" (multiple drugs users). Increased levels of aggressiveness and sensation seeking were evidenced both in minimal experimenters (ME) and habitual users (HU), without any significant difference, in comparison with abstinent students. Similarly, ME scored higher than abstinent subjects on EPQ for social coping impairment, but lower than HU. Parental care perception was lower in HU, but not in ME with, respect to abstinent subjects. Pearson inverse correlation was demonstrated between PBI scores and EPQ maladaptation and BDHI aggressiveness. Data from this preliminary pilot study suggest that temperamental traits and personality changes may be associated to early substance use "proneness" and reduced perception of parental care.

Math anxiety has an important impact on mathematical development and performance. However, although math anxiety is supposed to be a transcultural trait, assessment instruments are scarce and are validated mainly for Western cultures so far. Therefore, we aimed at examining the transcultural generality of math anxiety by a thorough investigation of the validity of math anxiety assessment in Eastern Europe. We investigated the validity and reliability of a Polish adaptation of the Abbreviated Math Anxiety Scale (AMAS), known to have very good psychometric characteristics in its original, American-English version as well as in its Italian and Iranian adaptations. We also observed high reliability, both for internal consistency and test-retest stability of the AMAS in the Polish sample. The results also show very good construct, convergent and discriminant validity: The factorial structure in Polish adult participants (n = 857) was very similar to the one previously found in other samples; AMAS scores correlated moderately in expected directions with state and trait anxiety, self-assessed math achievement and skill as well temperamental traits of emotional reactivity, briskness, endurance, and perseverance. Average scores obtained by participants as well as gender differences and correlations with external measures were also similar across cultures. Beyond the cultural comparison, we used path model analyses to show that math anxiety relates to math grades and self-competence when controlling for trait anxiety. The current study shows transcultural validity of math anxiety assessment with the AMAS. PMID:26648893

Some clinical studies on attention deficit hyperactivity disorder (ADHD) have been found to overlap those of studies on personality, particularly those on the Novelty Seeking trait (NS) as measured by the Junior Temperament and Character Inventory (JTCI). The aim of this study was to evaluate the potential role of NS in clinical research on ADHD. We enroled 146 ADHD children (125 boys; mean age=9.61, S.D.=2.50) and 223 age- and gender-matched control children (178 boys; mean age=9.41, S.D.=2.30). All the parents filled in the JTCI for the evaluation of personality according to Cloninger׳s model. An exploratory factor analysis differentiated the NS items that concern "Impulsivity" (NS1) from those that concern other features (NS2). Multivariate Analysis of Variance (MANOVAs) revealed significant differences between ADHD children and non-ADHD children in temperamental dimensions: the scores of ADHD children were higher than those of non-ADHD children in Total NS, NS1-Impulsivity and NS2. Our results show that the NS dimension of the JTCI in ADHD children is higher than in non-ADHD children, even when a correction is made for impulsivity items. This finding suggests that the NS trait plays a central role in ADHD diagnosis even when items referred to impulsivity are removed from the NS scale. Copyright © 2015 Elsevier Ireland Ltd.

Problems related to aggression in young people are traditionally subsumed under the header of conduct problems, which include conduct disorder and oppositional defiant disorder. Such problems in children and adolescents are an important societal and mental health problem. In this paper we present an evolutionarily informed developmental psychopathology view of conduct problems inspired by the NIMH Research Domain Criteria (RDoC) initiative. We assume that while there are many pathways to conduct problems, chronic or temporary impairments in the domain of social cognition or mentalizing are a common denominator. Specifically, we conceptualize conduct problems as reflecting temporary or chronic difficulties with mentalizing, that is, the capacity to understand the self and others in terms of intentional mental states, leading to a failure to inhibit interpersonal violence through a process of perspective-taking and empathy. These difficulties, in turn, stem from impairments in making use of a normally evolutionarily protected social learning system that functions to facilitate intergenerational knowledge transmission and protect social collaborative processes from impulsive and aggressive action. Temperamental, biological, and social risk factors in different combinations may all contribute to this outcome. This adaptation then interacts with impairments in other domains of functioning, such as in negative and positive valence systems and cognitive systems. This view highlights the importance of a complex interplay among biological, psychological, and environmental factors in understanding the origins of conduct problems. We outline the implications of these views for future research and intervention. Copyright © 2017 Elsevier Ltd. All rights reserved.

Purpose The purpose of this study was to assess the relation of behavioral inhibition to stuttering and speech/language output in preschool-age children who do (CWS) and do not stutter (CWNS). Method Participants were preschool-age (ages 36 to 68 months), including 26 CWS (22 males) and 28 CWNS (13 males). Participants’ behavioral inhibition (BI) was assessed by measuring the latency to their sixth spontaneous comment during conversation with an unfamiliar experimenter, using methodology developed by Kagan, Reznick, and Gibbons (1989). In addition to these measures of BI, each participant’s stuttered and non-stuttered disfluencies and mean length of utterance (in morphemes) were assessed. Results Among the more salient findings, it was found that (1) there was no significant difference in BI between preschool-age CWS and CWNS as a group, (2) when extremely high versus low inhibited children were selected, there were more CWS with higher BI and fewer CWS with lower BI when compared to their CWNS peers, and (3) more behaviorally inhibited CWS, when compared to less behaviorally inhibited CWS, exhibited more stuttering. Conclusions Findings are taken to suggest that one aspect of temperament (i.e., behavioral inhibition) is exhibited by some preschool-age CWS and that these children stutter more than CWS with lower behavioral inhibition. The present results seem to support continued study of the association between young children’s temperamental characteristics and stuttering, the diagnostic entity (i.e., CWS versus CWNS), as well as stuttering, the behavior (e.g., frequency of stuttered disfluencies).

Temperament appears to be a factor involved in professional attitudes. The most impressive findings are those on the importance of cyclothymia in art and of hyperthymia in leadership. In this study we raise the issue of whether the relationship between hyperthymic temperament and the choice of a military career, previously reported among Italian Air Force applicants, can be extended to another military service such as the Italian Navy. We compared temperaments between those who had applied to become a cadet officer in the Italian Air Force or in the Italian Navy, with special reference to gender differences and the ability of the two types of applicants to pass the psychiatric examination for admission that we had recently assessed in the Italian Air Force. Hyperthymic traits were well represented in both these armed services. Navy applicants differed from air-force applicants in obtaining higher depressive, cyclothymic and irritable scores. Navy applicants who passed the psychiatric entrance examination (PEE) showed the same incidence of hyperthymic temperament as their Air Force counterparts, but higher depressive, cyclothymic and irritable scores. Considering gender, among Air Force applicants depressive traits were better represented in males; conversely, among Navy applicants they were better represented in females. If we consider gender together with PEE results, the highest hyperthymic scores were more frequently found among males who passed and females who failed to pass the PEE. On the other hand, a greater number of cyclothymic traits were found in females who passed and males who failed to pass the PEE. It was confirmed that hyperthymic temperament represents the temperamental profile of those who aim to become a cadet officer in the Italian armed forces. This study further supports the idea that hyperthymic traits bring distinct advantages in a professional field, such as a military career, which is closely related to leadership.

Behaviorally inhibited children display a temperamental profile characterized by social withdrawal and anxious behaviors. Previous research, focused largely on adolescents, suggests that attention biases to threat may sustain high levels of behavioral inhibition (BI) over time, helping link early temperament to social outcomes. However, no prior studies examine the association between attention bias and BI before adolescence. The current study examined the interrelations among BI, attention biases to threat, and social withdrawal already manifest in early childhood. Children (N=187, 83 Male, Mage=61.96 months) were characterized for BI in toddlerhood (24 & 36 months). At 5 years, they completed an attention bias task and concurrent social withdrawal was measured. As expected, BI in toddlerhood predicted high levels of social withdrawal in early childhood. However, this relation was moderated by attention bias. The BI-withdrawal association was only evident for children who displayed an attention bias toward threat. The data provide further support for models associating attention with socioemotional development and the later emergence of clinical anxiety. PMID:21318555

Association studies of the serotonin transporter promoter polymorphism (5-HTTLPR) and negative emotionality (NE) are inconclusive. However, emerging evidence suggests that the association between this polymorphism and NE may be influenced by levels of another temperament trait, positive emotionality (PE). Therefore, this study examined whether the association between the 5-HTTLPR and NE was moderated by PE. A community sample of 413 three-year-old children completed a standardized battery of laboratory tasks designed to tap temperamental emotionality. Children were also genotyped for the 5-HTTLPR. No direct association between 5-HTTLPR genotype and NE was found. However, the interaction of child PE and NE predicted 5-HTTLPR genotype. Furthermore, children with a short allele who were also low in PE had significantly greater NE than children without a short allele or children with high PE. Our findings suggest that the short allele of the 5-HTTLPR is associated with NE only in the context of low PE. Inconsistent links between NE and this gene in previous research may stem from the failure to consider other temperament traits that moderate associations. PMID:21038952

Social anxiety disorder symptoms are generally proposed to be related to broad temperamental vulnerabilities (e.g., a low level of approach and high level of avoidance temperament), specific psychological vulnerabilities (e.g., fears of negative and positive evaluation), and additional disorders (e.g., major depressive disorder). However, existing tests of such a model have either not considered depressive symptoms or relied on samples of undergraduates. We examined these and related questions via a latent variable model in a large dataset (N=2253) that combined participants across a variety of studies. The model had adequate fit in the whole sample, and good fit in a subsample in which more participants completed the depression measure. The model indicated that low level of approach and high level of avoidance temperament contributed to fears of evaluation and social anxiety symptoms, and that fears of evaluation additionally contributed independently to social anxiety symptoms. The relationship between social anxiety and depressive symptoms was entirely accounted for by these vulnerabilities: Depressive symptoms were only predicted by avoidance temperament.

This study examined changes in coparenting after the birth of a second child. Mothers and fathers from 241 2-parent families reported on their spouses' coparenting cooperation and conflict with their firstborn children before (prenatal) and 4 months after the birth of a second child. Parents completed prenatal questionnaires on their gender-role attitudes, marital satisfaction, and firstborn children's temperamental characteristics. Parents also reported on their second-born infants' temperaments at 1 month of age. Coparenting conflict increased across the transition, and cooperation decreased. Couples in which fathers reported greater marital satisfaction were more cooperative 4 months after the second birth. Firstborns' difficult temperaments contributed to less cooperative coparenting by both parents. When mothers had more traditional gender-role beliefs, fathers engaged in more conflictual coparenting behavior, and when fathers had more traditional gender-role beliefs, mothers engaged in more conflictual coparenting behavior. Mothers, but not fathers, engaged in more coparenting conflict regarding the firstborn when both the firstborn and infant sibling had difficult temperaments.

The present prospective study examined the prediction of prosociality from effortful control and ego-resiliency from late adolescence to emerging adulthood. Participants were 476 young adults (239 males and 237 females) with a mean age of 16 years (SD = .81) at T1, 18 years (SD = .83) at T2, 20 years (SD = .79) at T3, 22 years (SD = .81) at T4, and 26 years (SD = .81) at T5. Controlling for the stability of the examined variables and the effect of potential confounding variables (i.e., sex, socioeconomic status [SES], and age), results supported a model in which a temperamental dimension, effortful control, positively predicted a specific behavioral tendency (i.e., prosociality) indirectly through mediation by a personality factor (i.e., ego-resiliency). Practical implications of the results are discussed in terms of the importance of early prevention efforts designed to enhance the capacity to cope effectively with emotional reactions and difficult situations. © 2014 by the Society for Personality and Social Psychology, Inc.

Affective Traits in Schizophrenia and Schizotypy

Horan, William P.; Blanchard, Jack J.; Clark, Lee Anna; Green, Michael F.

2008-01-01

This article reviews empirical studies of affective traits in individuals with schizophrenia spectrum disorders, population-based investigations of vulnerability to psychosis, and genetic and psychometric high-risk samples. The review focuses on studies that use self-report trait questionnaires to assess Negative Affectivity (NA) and Positive Affectivity (PA), which are conceptualized in contemporary models of personality as broad, temperamentally-based dispositions to experience corresponding emotional states. Individuals with schizophrenia report a pattern of stably elevated NA and low PA throughout the illness course. Among affected individuals, these traits are associated with variability in several clinically important features, including functional outcome, quality of life, and stress reactivity. Furthermore, evidence that elevated NA and low PA (particularly the facet of anhedonia) predict the development of psychosis and are detectable in high-risk samples suggests that these traits play a role in vulnerability to schizophrenia, though they are implicated in other forms of psychopathology as well. Results are discussed in terms of their implications for treatment, etiological models, and future research to advance the study of affective traits in schizophrenia and schizotypy. PMID:18667393

2017-05-01

The Cloninger's Psychobiological Model of Temperament and Character includes temperamental dimensions such as reward dependence (RD) and harm avoidance (HA). Studies of RD differentiate between sensitivity to reward (SR) versus to punishment (SP). We investigated the interrelationship between HA and RD in acutely ill patients with binge/purge (B/P) type eating disorders (EDs) and following symptomatic stabilization. Fifty patients with B/P EDs were assessed at admission to inpatient treatment, 36 of whom were reassessed at discharge. Thirty-six controls were similarly assessed. Participants completed Tridimensional Personality Questionnaire (TPQ), Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ), and took the Gambling Task. Patients with B/P EDs had higher TPQ-RD and lower TPQ-HA accompanied by lower SPSRQ-SR and SPSRQ-SP. SPSRQ-SP correlated positively and negatively with TPQ-HA and TPQ-RD, respectively. Combination of lower TPQ-HA, lower SPSRQ-SP, and greater risk-taking inclination may maintain disordered eating in patients with B/P EDs.

2017-01-01

The authors compared the relations between general psychological difficulties and dimensions of temperament in children with and without learning disability (LD). The main aim was to analyze whether and to what extent children's temperament dimensions contribute to their general psychological difficulties when LD diagnosis, age, and gender are taken into account. Participants were 52 elementary school children 7-11 years old (M age = 8.61 years, SD = 1.21 years). Twenty-six of them had been diagnosed with LD. Six teachers rated their pupils with and without LD in relation to their general psychological difficulties (Strengths and Difficulties Questionnaire) and temperament dimensions (Italian Questionnaires of Temperament). In children with LD, the main dimensions of temperament with the power to predict general psychological difficulties (i.e., emotionality and social orientation) concern these students' relationships with others (teachers and peers). The findings of the current study draw educators' and practitioners' attention to the fact that children's temperamental characteristics may affect how they experience their LD, with significant implications for their later social adjustment.

Photodynamic therapy (PDT) of dysplasia and early cancer of the esophagus could show good results in the potential of ablation. Unfortunately, the existing expensive and temperamental dye laser systems foiled a broad clinical use. In this pilot study, we investigated the feasibility of an inexpensive and maintenance-free diode laser system for PDT of dysplasia and early cancer in Barrett's esophagus. Eight patients with Barrett's esophagus and/or early cancer were treated. As light source we used a diode laser system with a maximum power output of 2 W and a wavelength of 633 +/- 3 nm. One patient was treated initially with Photosan-3, seven patients received 5-aminolevulinic acid. In all patients we could achieve reduction in length and/or histologically proven downgrading. In three quarters of the patients, complete eradication of adenocarcinoma could be attained. Columnar-lined metaplastic epithelium could also be completely eradicated. PDT using a diode laser system is comparably effective in Barrett's esophagus/early cancer as PDT with dye laser systems. PDT is a gentle and effective technique with little side effects.

The association of anxiety disorders and obsessive compulsive personality disorder with anorexia nervosa: evidence from a family study with discussion of nosological and neurodevelopmental implications.

To investigate the association of anorexia nervosa with anxiety disorders through use of a case-control family study design. Lifetime prevalence of anxiety disorders and obsessive compulsive personality disorder was determined among 574 first-degree relatives of 152 probands with anorexia nervosa and compared to rates observed among 647 first-degree relatives of 181 never-ill control probands. Adjusting for comorbidity of the same illness in the proband, relatives of probands with anorexia nervosa, had a significantly higher prevalence of generalized anxiety, obsessive compulsive disorder, separation anxiety disorder, social phobia, panic disorder, and obsessive compulsive personality disorder compared to relatives of never-ill control probands. Anorexia nervosa may share familial liability factors in common with various anxiety phenotypes. In suggesting that a transmitted propensity for anxiety is a key aspect of vulnerability in anorexia nervosa, the findings point to research developments in the affective neurosciences, specifically the neurocircuitry of fear and anxiety, as a heuristic framework in which to interpret aspects of premorbid temperamental anxieties and clinical symptoms.

The aim of this study was to investigate the relationship between personality and sexual motivation according to Cloninger's psychobiological model of the personality. Three hundred and ten volunteers recruited among the students of the University of Messina, Italy, participated in the study. 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.

Infant and maternal predictors of early life feeding decisions: The timing of solid food introduction

2015-01-01

There is limited research on the maternal and infant characteristics associated with the timing of solid food introduction. The current study examined how maternal feeding style and infant temperament independently and interactively predicted the age at which infants were introduced to solid food. Data from 115 predominately white, middle-class mothers were collected when infants were 4 and 6 months of age. The timing of solid food introduction was positively correlated with mothers' age, education, breastfeeding at 4 months, self-reported responsiveness to infants' hunger and satiety cues, and negatively correlated with mothers' pre-pregnancy body mass index (BMI), beliefs about feeding infants solid food prior to 6 months of age, and infants' temperamental motor reactivity. When controlling for maternal age, education, pre-pregnancy BMI, and milk feeding method at 4 months, the timing of solid food introduction was negatively predicted by mothers' beliefs about feeding solid food prior to 6 months of age. Exploratory interaction analyses suggested that infant temperament marginally moderated maternal feeding style in predicting the timing of solid food introduction. PMID:26025089

Dysthymia and cyclothymia in psychiatric practice a century after Kraepelin.

PubMed

Akiskal, H S

2001-01-01

Kraepelin had a modern vision of affective illness. He hypothesized that affective recurrences arose from enduring dispositions of depressive, cyclothymic, irritable, or 'manic' types. These dispositions appeared as 'temperaments' in English translations of his work. In the extreme, such temperamental gloominess or moodiness is today officially diagnosed as 'dysthymic' or 'cyclothymic'; irritable and hyperthymic (or manic) dispositions have not received official sanction in the contemporary psychiatric nomenclature. This paper reviews recent research which supports Kraepelin's theoretical framework regarding dysthymic and cyclothymic dispositions both as clinically relevant extreme forms of temperament and as precursors of major affective episodes. Compelling lines of evidence along epidemiologic, clinical-descriptive, familial-genetic, therapeutic, and follow-up perspectives are summarized for each disposition. Much of what in contemporary psychiatry is considered to be in the realm of subthreshold affective conditions, overlaps considerably with Kraepelin's concepts of the trait affective dispositions described herein. Most importantly, although Kraepelin's observations were based primarily on hospitalized, severely ill affective patients, his broad vision still guides us today for understanding etiology and instituting public health and preventive measures in major affective episodes.

Sex-specific relationships among attachment security, social values, and sensation seeking in early adolescence: implications for adolescents' externalizing problem behaviour.

In early adolescence, attachment security reflects not only the quality of ongoing relationships with parents, but also how adolescents process social relationships with "others" - that is, their "social value orientation" - with possible implications for adolescents' risk-taking. In this study, a sample of Italian early adolescents were administered self-report measures in order to examine the relationships (a) between early adolescents' perceived attachment security to mothers and fathers, social values (related to family and the socio-cultural context), and sensation seeking (as a temperamental predisposition to risk-taking), and (b) between these variables and adolescents' externalizing problem behaviour. Adolescents were more securely attached to the same-sexed parent. Further, attachment security with the opposite-sexed parent predicted more conservative social value orientations, and lower levels of problem behaviour. In contrast, sensation seeking predicted self-enhancement and openness-to-change values to a greater extent, and, in girls, lower levels of attachment security to mothers and fathers.

Objective. Group fighting is portrayed as a piece of Americana among delinquent youth, but the behavior produces significant multifaceted negative consequences. The current study examines the heterogeneity and correlates of group fighting using national-level data. Method. Employing data from the National Survey on Drug Use and Health between 2002 and 2013 (n = 216,852), we examine links between group fighting and temperamental, parental, and academic factors as well as other externalizing behaviors (i.e., violence, crime, substance use). Results. The prevalence of group fighting in the United States is 14.8% with 11.33% reporting 1–2 group fights and 3.46% reporting 3+ group fights. A clear severity gradient in school functioning and academic performance, sensation seeking, parental disengagement, violence and delinquency, and substance use disorders is seen in the normative, episodic, and repeat offender groups. Conclusions. Youths who participate in 3+ group fights display the exceptionality and severity of other serious/chronic/habitual antisocial youth which suggests that group fighting should be considered a significant indicator of developing criminality.

Harsh Parenting and Fearfulness in Toddlerhood Interact to Predict Amplitudes of Preschool Error-Related Negativity

PubMed Central

Brooker, Rebecca J.; Buss, Kristin A.

2014-01-01

Temperamentally fearful children are at increased risk for the development of anxiety problems relative to less-fearful children. This risk is even greater when early environments include high levels of harsh parenting behaviors. However, the mechanisms by which harsh parenting may impact fearful children’s risk for anxiety problems are largely unknown. Recent neuroscience work has suggested that punishment is associated with exaggerated error-related negativity (ERN), an event-related potential linked to performance monitoring, even after the threat of punishment is removed. In the current study, we examined the possibility that harsh parenting interacts with fearfulness, impacting anxiety risk via neural processes of performance monitoring. We found that greater fearfulness and harsher parenting at 2 years of age predicted greater fearfulness and greater ERN amplitudes at age 4. Supporting the role of cognitive processes in this association, greater fearfulness and harsher parenting also predicted less efficient neural processing during preschool. This study provides initial evidence that performance monitoring may be a candidate process by which early parenting interacts with fearfulness to predict risk for anxiety problems. PMID:24721466

Chronotype has long been associated with mental disorders and temperamental features. This study aims to investigate the association of circadian preference with a new model for emotional and affective temperament. In this Web survey, 6436 subjects (27.2% males) answered the Affective and Emotional Composite Temperament Scale (AFECTS), the Circadian Energy Scale (CIRENS), and questions on subjective sleep parameters for a sleep-based chronotype measure. Temperament was more strongly correlated with daily energy score than with chronotype. For emotional dimensions, Volition, Coping, and Control positively correlated with high and stable daily energy, contrary to Sensitivity. Evening types showed a less adaptive emotional profile than morning and intermediate types, who showed a relatively similar emotional pattern. Focus and order (facets of Control), energy (facet of Volition), caution (facet of Inhibition), and problem facing (facet of Coping) were distinctive for the three circadian types, being particularly low in evening types and high in morning types. Differences between affective temperaments were more pronounced for morning and afternoon than for evening scores. Cyclothymic and euphoric temperaments, which relate to bipolar disorders, and apathetic, volatile, and disinhibited temperaments, which relate to attention-deficit/hyperactivity disorder (ADHD), showed the latest chronotype (i.e., evening preference). In conclusion, temperament was more associated with absolute energy levels than with chronotype. Evening types had less emotional control, coping, volition, and caution, and more affective instability and externalization. The circadian daily energy profile can be very informative about human temperament and vice versa, and their combined assessment may be useful in the evaluation of psychiatric patients.

Objective To find, review, and critically evaluate evidence pertaining to the phenomenology of pediatric bipolar disorder and its validity as a diagnosis. Methods The present qualitative review summarizes and synthesizes available evidence about the phenomenology of bipolar disorder (BD) in youths, including description of the diagnostic sensitivity and specificity of symptoms, clarification about rates of cycling and mixed states, and discussion about chronic versus episodic presentations of mood dysregulation. The validity of the diagnosis of BD in youths is also evaluated based on traditional criteria including associated demographic characteristics, family environmental features, genetic bases, longitudinal studies of youths at risk of developing BD as well as youths already manifesting symptoms on the bipolar spectrum, treatment studies and pharmacologic dissection, neurobiological findings (including morphological and functional data), and other related laboratory findings. Additional sections review impairment and quality of life, personality and temperamental correlates, the clinical utility of a bipolar diagnosis in youths, and the dimensional versus categorical distinction as it applies to mood disorder in youths. Results A schema for diagnosis of BD in youths is developed, including a review of different operational definitions of `bipolar not otherwise specified.' Principal areas of disagreement appear to include the relative role of elated versus irritable mood in assessment, and also the limits of the extent of the bipolar spectrum – when do definitions become so broad that they are no longer describing `bipolar' cases? Conclusions In spite of these areas of disagreement, considerable evidence has amassed supporting the validity of the bipolar diagnosis in children and adolescents. PMID:18199237

The original norms for the Revised Infant Temperament Questionnaire (RITQ) were published in 1978 and were based on a small sample from the US. The aim of this study is to compare temperament scores from the original RITQ against scores from a large population-based cohort of infants from the UK. This study consists of 10,937 infants from the Avon Longitudinal Study of Parents and Children (ALSPAC) born between April 1991 and December 1992 in the southwest of England. Infant temperament at 6 months of age was reported by parents using the adapted RITQ. Responses were scored according to the RITQ manual and then categorized into temperament groups (easy, intermediate low, intermediate high, and difficult) using either the RITQ norms or norms derived from the data. The scores for each temperament subscale and the proportion of children in each temperament group were compared across the two methods. Subscale scores for the ALSPAC sample were higher (more "difficult") than the RITQ norms for rhythmicity, approach, adaptability, intensity, and distractibility. When RITQ norms were applied, 24% infants were categorized as difficult and 25% as easy, compared with 15% difficult and 38% easy when ALSPAC norms were used. There are discrepancies between RITQ norms and the ALSPAC norms which resulted in differences in the distribution of temperament groups. There is a need to re-examine RITQ norms and categorization for use in primary care practice and contemporary population-based studies. Copyright © 2015 Elsevier Inc. All rights reserved.

In Japan, TEMPS-A has gathered much attention, because Kraepelin's concepts on "fundamental states" of mood disorder and temperaments have been widely respected. TEMPS-A was translated into Japanese (and after the approval of the English back translation by H.S.A.), it was administered to 1391 non-clinical subjects, and 29 unipolar and 30 bipolar patients in remission. Of the non-clinical sample, 426 were readministered the instrument again in 1 month. A control group matched for gender and age was drawn from the non-clinical sample. Regarding test-retest reliability, Spearman's coefficients for depressive, cyclothymic, hyperthymic, irritable and anxious temperaments were 0.79, 0.84, 0.87, 0.81 and 0.87, respectively; regarding internal consistency, Cronbach's alpha coefficients were 0.69, 0.84, 0.79, 0.83 and 0.87, respectively. The unipolar and bipolar groups showed significantly higher depressive, cyclothymic and anxious temperament scores than the control group. Curiously, the bipolar group showed significantly lower hyperthymic score than the control group; irritable temperament scores showed no significant differences. Depressive, cyclothymic, irritable and anxious temperament scores showed significant correlations with each other. Between the unipolar and bipolar groups, there was little difference regarding the temperament scores. Also the inter-temperament correlations showed the same pattern in the unipolar and bipolar groups. The clinically well cohort was 70% male. TEMPS-A showed a high reliability and validity (internal consistency) in a Japanese non-clinical sample. By and large, the hypothesized five temperament structure was upheld. Depressive, cyclothymic and anxious temperaments showed concurrent validity with mood disorder. Irritable temperament may represent a subtype of depressive, cyclothymic or anxious temperaments. There may be a temperamental commonality between unipolar and bipolar disorders. TEMPS-A will open new possibilities for international research on mood disorder and personality traits.

The results of two self-administered, paper-and-pencil tests based on biosocial theory of personality have been compared simultaneously: the Temperament and Character Inventory (TCI) and NEO Five Factor Inventory (NEO-FFI). The stability of the personality dimensions was assessed across age, sex and education level samples in a group of 406 Polish adults with major mental diseases excluded by use of PRIME-MD questionnaire. Significant effects of age, sex, and education have been found while comparing personality dimensions in both temperamental (novelty seeking, NS; harm avoidance, HA; reward dependence, RD; persistence, P) and character scales (cooperativeness, C; self-transcendence, ST) in TCI. Among subscales of temperament only NS1, RD4 were stable according to concerning factors. All converted to their age and sex norms NEO-FFI dimensions were stable according to sex. Extraversion scale was changeable depending on age (p = 0.04). Neuroticism dimension was a little higher in lower educated group (p = 0.035).To sum up, it was concluded that sex- and age-specific norms for the dimensions of the Polish version of TCI are necessary considering the established significant differences. Particular personality genetic studies should account for age, sex and also educational differences in their methods of associative studies. In the exploration of personality dimensions on healthy volunteers the Polish version of NEO-FFI corresponds better than TCI to theory of stability and genetic determinants of human personality. As the study included persons with excluded major mental diseases, the sample is appropriate to provide a control group in the research of psychiatric patients using both TCI and NEO-FFI. TCI scores for persons with excluded mental disease are highly changeable depending on age, sex and education. Adjusted to sex and age scores NEO-FFI corresponded better than TCI to stability and genetic determinants of human personality.

The role of food experiences during early childhood in food pleasure learning.

Nicklaus, Sophie

Infants are born equipped to ingest nutrients, but have to learn what to eat. This must occur early, because the mode of feeding evolves dramatically, from "tube" feeding in utero to eating family foods. Eating habits established during early years contribute to the development of subsequent eating habits. Therefore, it is fundamental to understand the most important early periods (between birth and 2 years, i.e. onset of food neophobia) for the development of eating habits and the drivers of this development. The role of pleasure in eating is central, especially during childhood when cognitive drivers of food choices may be less prominent than later in life. It is not easy to define and measure pleasure of eating in early childhood. However, it is possible to identify the characteristics of the eating experience which contribute to drive infant's eating and to shape preferences (food sensory properties; food rewarding properties; social context of eating). The learning processes involve repeated exposure (including to a variety of flavours), association with post-absorptive consequences and with contextual signals (including family members). The important early periods for learning food pleasure start being well identified. Beyond the first flavour discoveries during the prenatal and lactation periods (through the infant's exposure to flavours from foods of the mother's diet), the most important phase may be the beginning of complementary feeding. Infants discover the sensory (texture, taste and flavour) and nutritional properties (energy density) of the foods that will ultimately compose their adult diet; parents are still in charge of providing appropriate foods, timing, context for eating. Inter-individual differences in food pleasure learning, related to temperamental dimensions, or to sensory sensitivity also have to be taken into account. Copyright © 2015 Elsevier Ltd.

AFECTS is a novel psychometric instrument that provides an integrated framework based on affective temperamental traits and their trait dimensions. It has the potential to be used in clinical and research fields to study psychopathology and mental health. It is now necessary to field-test this instrument with diverse populations and psychopathological entities. The primary aim was to test the construct validity and the internal consistency of the Spanish Version of the AFECTS instrument on Mexican subjects. AFECTS characteristics were then compared between general population and stable psychiatric patients. A cross-sectional design involving 350 subjects from the general population in México City and 91 stable patients with a bipolar disorder (BPD, n=20), major depressive disorder (MDD, n=35), or with a schizophrenia (n=36) diagnosis. A six-factor structure in trait dimensions, explaining 61.4% of the variance, with a Cronbach׳s alpha of 0.93 was found. Euthymic (23%) and hyperthymic (12%) affective temperaments were the most frequent, while dysphoric (3%) and apathetic (3%) were the least. Trait dimension differences were found in Volition, Sensitivity, and the Instability Index between the groups, particularly those with a bipolar disorder. Use of a self report instrument, and a small sample not representative of the Mexican population or patients with psychiatric conditions. The Spanish Version of the AFECTS instrument has adequate psychometric properties. This version of AFECTS will allow the use of this instrument among Spanish speaking populations and contribute to the continued research efforts on integrative models such as AFECT.

Alm, Per A; Risberg, Jarl

2007-01-01

The purpose of this study was to investigate the relation between stuttering and a range of variables of possible relevance, with the main focus on neuromuscular reactivity, and anxiety. The explorative analysis also included temperament, biochemical variables, heredity, preonset lesions, and altered auditory feedback (AAF). An increased level of neuromuscular reactivity in stuttering adults has previously been reported by [Guitar, B. (2003). Acoustic startle responses and temperament in individuals who stutter. Journal of Speech Language and Hearing Research, 46, 233-240], also indicating a link to anxiety and temperament. The present study included a large number of variables in order to enable analysis of subgroups and relations between variables. Totally 32 stuttering adults were compared with nonstuttering controls. The acoustic startle eyeblink response was used as a measure of neuromuscular reactivity. No significant group difference was found regarding startle, and startle was not significantly correlated with trait anxiety, stuttering severity, or AAF. Startle was mainly related to calcium and prolactin. The stuttering group had significantly higher scores for anxiety and childhood ADHD. Two subgroups of stuttering were found, with high versus low traits of childhood ADHD, characterized by indications of preonset lesions versus heredity for stuttering. The study does not support the view that excessive reactivity is a typical characteristic of stuttering. The increased anxiety is suggested to mainly be an effect of experiences of stuttering. As a result of reading this article, the reader will be able to: (a) critically discuss the literature regarding stuttering in relation to acoustic startle, anxiety, and temperament; (b) describe the effect of calcium on neuromuscular reactivity; (c) discuss findings supporting the importance of early neurological incidents in some cases of stuttering, and the relation between such incidents and traits of ADHD or ADD; and (d) discuss the role of genetics in stuttering.

Child's positive and negative impacts on parents--a person-oriented approach to understanding temperament in preschool children with intellectual disabilities.

Despite previous efforts to understand temperament in children with intellectual disability (ID), and how child temperament may affect parents, the approach has so far been unidimensional. Child temperament has been considered in relation to diagnosis, with the inherent risk of overlooking individual variation of children's temperament profiles within diagnostic groups. The aim of the present study was to identify temperamental profiles of children with ID, and investigate how these may affect parents in terms of positive and negative impacts. Parent-rated temperament in children with ID was explored through a person-oriented approach (cluster analysis). Children with ID (N=49) and typically developing (TD) children (N=82) aged between 4 and 6 years were clustered separately. Variation in temperament profiles was more prominent among children with ID than in TD children. Out of the three clusters found in the ID group, the disruptive, and passive/withdrawn clusters were distinctly different from clusters found in the TD group in terms of temperament, while the cluster active and outgoing was similar in shape and level of temperament ratings of TD children. Children within the disruptive cluster were described to have more negative and less positive impacts on mothers compared to children within the other clusters in the ID group. Mothers who describe their children as having disruptive temperament may be at particular risk for experiencing higher parenting stress as they report that the child has higher negative and lower positive impacts than other parents describe. The absence of a relationship between child temperament profile and positive or negative impact on fathers may indicate that fathers are less affected by child temperament. However, this relationship needs to be further explored. Copyright © 2011 Elsevier Ltd. All rights reserved.

Standardized testing has become a common form of student evaluation with high stakes, and limited research exists on understanding the roles of students' personality traits and social-evaluative threat on their academic performance. This study examined the roles of avoidance temperament (i.e., fear and behavioral inhibition) and evaluative threat (i.e., fear of failure and being viewed as unintelligent) in standardized math test and course grades in college students. Undergraduate students (N=184) from a large public university were assessed on temperamental fear and behavioral inhibition. They were then given 15 minutes to complete a standardized math test. After the test, students provided data on evaluative threat and their math performance (scores on standardized college entrance exam and average grades in college math courses). Results indicate that avoidance temperament was linked to social-evaluative threat and low standardized math test scores. Furthermore, evaluative threat mediated the influence of avoidance temperament on both types of math performance. Results have educational and clinical implications, particularly for students at risk for test anxiety and underperformance. Interventions targeting emotion regulation and stress management skills may help individuals reduce their math and test anxieties.

This study examined the contributions of several important domains of functioning to attention-deficit/hyperactivity disorder (ADHD) symptoms and conduct problems. Specifically, we investigated whether cognitive inhibition, emotion regulation, emotionality, and disorganized attachment made independent and specific contributions to these externalizing behaviour problems from a multiple pathways perspective. The study included laboratory measures of cognitive inhibition and disorganized attachment in 184 typically developing children (M age = 6 years, 10 months, SD = 1.7). Parental ratings provided measures of emotion regulation, emotionality, and externalizing behaviour problems. Results revealed that cognitive inhibition, regulation of positive emotion, and positive emotionality were independently and specifically related to ADHD symptoms. Disorganized attachment and negative emotionality formed independent and specific relations to conduct problems. Our findings support the multiple pathways perspective on ADHD, with poor regulation of positive emotion and high positive emotionality making distinct contributions to ADHD symptoms. More specifically, our results support the proposal of a temperamentally based pathway to ADHD symptoms. The findings also indicate that disorganized attachment and negative emotionality constitute pathways specific to conduct problems rather than to ADHD symptoms. © 2016 The British Psychological Society.

Resilience among African American adolescent mothers: predictors of positive parenting in early infancy.

To use Nath et al.'s (1991) conceptual model of adolescent parenting to examine the relationship between resiliency factors measured shortly after delivery and maternal parenting behavior at 6 months. We recruited 181 first-time, adolescent African American mothers at delivery. Data on resiliency factors (maturity, self-esteem, and mother-grandmother relationships) were collected when infants were 1-4 weeks of age. Data on parental nurturance and parenting satisfaction were examined through observations and self-report at 6 months. Multiple regression analyses were used to examine the longitudinal impact of resiliency factors on parental nurturance and parenting satisfaction. Maternal maturity, positive self-esteem, and positive adolescent mother-grandmother relationships (characterized by autonomy and mutuality) were associated with better parenting outcomes. Maternal parenting satisfaction was lowest when infants were temperamentally difficult and mothers and grandmothers had a confrontational relationship. Longitudinal associations between mother-grandmother relationships at delivery and parental behavior and satisfaction 6 months later may suggest an intergenerational transmission of parenting style. Recommendations are provided for intervention programs to enhance mother-grandmother relationships in contexts where adolescents are required to live with a guardian to receive government assistance.

Parental anxiety confers risk for the development of an anxiety disorder in children, and this risk may be transmitted through children's stress reactivity. Further, some children may be more vulnerable to reactivity in the presence of parent factors such as anxiety. In this study, we examined whether parents' anxiety symptoms prospectively predict school-aged children's physiological reactivity following stress, assessed through their electrodermal activity (galvanic skin response) during recovery from a performance challenge task, and whether this varies as a function of children's temperamental fearfulness. Parents and their children (N = 68) reported on their anxiety symptoms at Time 1 of data collection, and parents characterized the extent to which their children had fearful temperaments. At Time 2 children completed the performance challenge and two recovery tasks. Greater parental anxiety symptom severity at Time 1 predicted children's higher electrodermal response during both recovery tasks following the failure task. Further, these effects are specific to children with medium and high fearful temperament, whereas for children low in fearfulness, the association between parent anxiety and child reactivity is not significant. Findings provide additional evidence for the diathesis-stress hypothesis and are discussed in terms of their contribution to the literature on developmental psychopathology.

Anger is a negative emotion associated with approach motivation and may influence children's attention preference. Three experiments examined the effect of anger on the attentional biases accompanying reward versus punishment cues in Chinese 5- and 6-year-olds. Experiment 1 tested children who were prone to report angry feelings in an unfair game. Experiment 2 measured children who were rated by parents and teachers for temperamental anger. Experiment 3 explored children who reported angry feelings in a frustrating attention task with rigged and noncontingent feedback after controlling for temperament anger. Results suggested that both the angry and anger-prone children were faster to engage attention toward the reward cues than toward the punishment cues in the three experiments. Furthermore, the angry children in the frustrating attention task (and those with poor attention focusing by parental report) were slower in disengaging attention away from the reward versus punishment cues (especially after negative feedback). Results support the approach motivation of anger, which can facilitate children's attention toward the appetitive approach-related information. The findings are discussed in terms of the adaptive and maladaptive function of anger. Copyright © 2013 Elsevier Inc. All rights reserved.

Personality Predictors of Successful Development: Toddler Temperament and Adolescent Personality Traits Predict Well-Being and Career Stability in Middle Adulthood

PubMed Central

2015-01-01

The aim of the study was to predict both adaptive psychological functioning (well-being) and adaptive social functioning (career stability) in middle adulthood based on behaviors observed in toddlerhood and personality traits measured in adolescence. 83 people participated in an ongoing longitudinal study started in 1961 (58% women). Based on children’s behavior in toddlerhood, three temperamental dimensions were identified – positive affectivity, negative affectivity and disinhibition. In adolescence, extraversion and neuroticism were measured at the age of 16 years. Various aspects of well-being were used as indicators of adaptive psychological functioning in adulthood: life satisfaction, self-esteem and self-efficacy. Career stability was used as an indicator of adaptive social functioning. Job careers of respondents were characterized as stable, unstable or changeable. Extraversion measured at the age of 16 proved to be the best predictor of well-being indicators; in case of self-efficacy it was also childhood disinhibition. Extraversion in adolescence, childhood disinhibition and negative affectivity predicted career stability. Findings are discussed in the context of a theoretical framework of higher order factors of the Big Five personality constructs, stability and plasticity. PMID:25919394

This study examined the effects of parents’ positive and negative affect and behavior while interacting with their preschool child and the moderating role of child temperament in predicting children’s subsequent difficulty with socially appropriate behavior around school-entry. Independent observational measures were used to assess child temperament (dysphoria; exuberance) and parenting at age 3, and multi-informant reports of child socially appropriate behavior were collected at age 6 (N = 219). Hierarchical multiple regression analyses revealed that children’s temperamental dysphoria moderated the relationship between positive parenting and later socially appropriate behavior. High- and low-dysphoric children trended in opposite directions; highly dysphoric children experienced greater difficulty with socially appropriate behavior as levels of positive parenting increased, whereas low-dysphoric children experienced less difficulty with socially appropriate behavior with higher levels of positive parenting. There was also an interaction between positive and negative parenting, whereby the combination of elevated positive and negative parenting predicted children’s later difficulty with socially appropriate behavior. The findings suggest that positive parenting interacts with early child temperament and negative parenting to impact the development of children’s socially appropriate behavior. PMID:28824223

Infant EEG and temperament negative affectivity: Coherence of vulnerabilities to mothers' perinatal depression.

2016-11-01

Associations between infants' frontal EEG asymmetry and temperamental negative affectivity (NA) across infants' first year of life and the potential moderating role of maternal prenatal depressive symptoms were examined prospectively in infants (n = 242) of mothers at elevated risk for perinatal depression. In predicting EEG, in the context of high prenatal depressive symptoms, infant NA and frontal EEG asymmetry were negatively associated at 3 months of age and positively associated by 12 months of age. By contrast, for low depression mothers, infant NA and EEG were not significantly associated at any age. Postnatal depressive symptoms did not add significantly to the models. Dose of infants' exposure to maternal depression mattered: infants exposed either pre- or postnatally shifted from a positive association at 3 months to a negative association at 12 months; those exposed both pre- and postnatally shifted from a negative association at 3 months to a positive association at 12 months. Prenatal relative to postnatal exposure did not matter for patterns of association between NA and EEG. The findings highlight the importance of exploring how vulnerabilities at two levels of analysis, behavioral and psychophysiological, co-occur over the course of infancy and in the context of mothers' depressive symptomatology.

2016-11-01

Children's depressive symptoms in the transition from preschool to school are rarely investigated. We therefore tested whether children's temperament (effortful control and negative affect), social skills, child psychopathology, environmental stressors (life events), parental accuracy of predicting their child's emotion understanding (parental accuracy), parental emotional availability, and parental depression predict changes in depressive symptoms from preschool to first grade. Parents of a community sample of 995 4-year-olds were interviewed using the Preschool Age Psychiatric Assessment. The children and parents were reassessed when the children started first grade (n = 795). The results showed that DSM-5 defined depressive symptoms increased. Child temperamental negative affect and parental depression predicted increased, whereas social skills predicted decreased, depressive symptoms. However, such social skills were only protective among children with low and medium effortful control. Further, high parental accuracy proved protective among children with low effortful control and high negative affect. Thus, interventions that treat parental depression may be important for young children. Children with low effortful control and high negative affect may especially benefit from having parents who accurately perceive their emotional understanding. Efforts to enhance social skills may prove particularly important for children with low or medium effortful control.

The effects of temperament, psychopathy, and childhood trauma among delinquent youth: A test of DeLisi and Vaughn's temperament-based theory of crime.

PubMed

DeLisi, Matt; Fox, Bryanna H; Fully, Matthew; Vaughn, Michael G

Recent interest among criminologists on the construct of temperament has been fueled by DeLisi and Vaughn's (2014) temperament-based theory of antisocial behavior. Their theory suggests that core self-regulation capacity and negative emotionality are the most salient temperament features for understanding the emergence and maintenance of antisocial and violent behavior, even among offending populations. The present study tests the relative effects of these temperamental features along with psychopathic traits and trauma in their association with violent and non-violent delinquency in a sample of 252 juvenile offenders. Results from a series of negative binomial regression models indicate that temperament was uniformly more strongly associated with violent and non-violent delinquency than psychopathic traits and childhood traumatic events. Exploratory classification models suggested that temperament and psychopathy possessed similar predictive capacity, but neither surpassed prior history of violence and delinquency as a predictor of future offending. Overall, findings are supportive of DeLisi and Vaughn's temperament-based theory and suggest temperament as conceptualized and measured in the present study may play an important role as a risk factor for violent and non-violent delinquency.

2012-05-01

This report describes the state of the art in distinguishing data generated by differential susceptibility from diathesis-stress models. We discuss several limitations of existing practices for probing interaction effects and offer solutions that are designed to better differentiate differential susceptibility from diathesis-stress models and quantify their corresponding implications. In addition, we demonstrate the utility of these methods by revisiting published evidence suggesting that temperamental difficulty serves as a marker of enhanced susceptibility to early maternal caregiving across a range of outcome domains in the NICHD Study of Early Child Care and Youth Development. We find that, with the exception of mother reports of psychopathology, there is consistent evidence in the Study of Early Child Care and Youth Development that the predictive significance of early sensitivity is moderated by difficult temperament over time. However, differential susceptibility effects emerged primarily for teacher reports of academic skills, social competence, and symptomatology. In contrast, effects more consistent with the diathesis-stress model were obtained for mother reports of social skills and objective tests of academic skills. We conclude by discussing the value of the application of this work to the next wave of Gene × Environment studies focused on early caregiving experiences.

Childhood negative emotionality predicts biobehavioral dysregulation 15 years later

The temperamental trait of negative emotionality (NE) plays an important role in maladaptation among adults experiencing significant life stress. However, the prospective relation between childhood NE and subsequent inter-related behavioral, emotional, and biological dysregulation in later life has not yet been established among children who experience early adversity. Using a longitudinal sample of youth who experienced parental divorce during childhood (N = 160; 53% male; 83% White), we tested the hypothesis that childhood NE would predict physiological, emotional, and behavioral dysregulation 15 years later. NE was assessed by maternal report when youth were between 9-12 years old. Fifteen years later, young adults (mean age = 25.55 years) participated in a psychosocial stress task to assess cortisol reactivity and reported on internalizing symptoms and problematic alcohol use. Structural equation modeling revealed that higher childhood NE predicted significantly greater alcohol use, internalizing symptoms, and total cortisol output during a stress task 15 years later. Importantly, these findings held adjusting for childhood internalizing symptoms. In addition, problematic alcohol use was associated with greater cortisol reactivity and internalizing symptoms. Findings suggest that childhood NE is a critical risk marker for interrelated forms of dysregulation in young adulthood among at-risk youth. PMID:27100364

Despite a plethora of studies, controversies abound on whether the long-term traits of unipolar and bipolar patients could be differentiated by temperament and whether these traits, in turn, could be distinguished from subthreshold affective symptomatology. 98 bipolar I (BP-I), 64 bipolar II (BP-II), and 251 unipolar major depressive disorder (UP-MDD) patients all when recovered from discrete affective episodes) and 617 relatives, spouses or acquaintances without lifetime RDC diagnoses (the comparison group, CG) were administered a battery of 17 self-rated personality scales chosen for theoretical relevance to mood disorders. Subsamples of each of the four groups also received the General Behavior Inventory (GBI). Of the 436 personality items, 103 that significantly distinguished the three patient groups were subjected to principal components analysis, yielding four factors which reflect the temperamental dimensions of "Mood Lability", "Energy-Assertiveness," "Sensitivity-Brooding," and "Social Anxiety." Most BP-I described themselves as near normal in emotional stability and extroversion; BP-II emerged as labile in mood, energetic and assertive, yet sensitive and brooding; MDD were socially timid, sensitive and brooding. Gender and age did not have marked influence on these overall profiles. Within the MDD group, those with baseline dysthymia were the most pathological (i.e., high in neuroticism, insecurity and introversion). Selected GBI items measuring hypomania and biphasic mood changes were endorsed significantly more often by BP-II. Finally, it is relevant to highlight a methodologic finding about the precision these derived temperament factors brought to the UP-BP differentiation. Unlike BP-I who were low on neuroticism, both BP-II and UP scored high on this measure: yet, in the case of BP-II high neuroticism was largely due to mood lability, in UP it reflected subdepressive traits. We used self-rated personality measures, a possible limitation generic to the paper-and-pencil personality literature. It is therefore likely that BP-I may have over-rated their "sanguinity"; or should one consider such self-report as a reliable reflection of one's temperament? One can raise similar unanswerable questions about "depressiveness" and "mood lability." As contrasted to CG and published norms, the postmorbid self-described "usual" personality is 1) sanguine among many, but not all, BP-I; 2) labile or cyclothymic among BP-II; and 3) subanxious and subdepressive among UP. It is further noteworthy that with the exception of BP-II, the temperament scores of BP-I and MDD were within one SD from published norms. Rather than being pathological, these attributes are best conceived as subclinical temperamental variants of the normal, thereby supporting the notion of continuity between interepisodic and episodic phases of affective disorders. These findings overall are in line with Kraepelin's views and contrary to the DSM-IV formulation of axis-II constructs as being pathological and sharply demarcated from affective episodes.

Orbitofrontal Cortex Volume and Effortful Control as Prospective Risk Factors for Substance Use Disorder in Adolescence.

Orbitofrontal cortex (OFC) dysfunction has been proposed to increase the risk for developing a substance use disorder (SUD) during adolescence. In this study, we suggest that a reduction in OFC volumes might underlie temperament-based risk factors for SUD, and examined whether smaller OFC volumes during early adolescence could predict later development of SUD. Adolescents (n = 107; 58 male, 49 female) underwent structural MRI and completed a self-report measure of temperamental effortful control at age 12. At 3 subsequent assessments (aged 15, 16, and 18) SUD was assessed via a semi-structured clinical interview. By the third assessment, 24 participants (22.4%) had received a lifetime diagnosis of SUD. Smaller volumes of the left OFC, right OFC, and left medial subregions predicted lifetime history of SUD by age 18. Volumes of the left OFC and left lateral subregions were positively correlated with effortful control, and left OFC volumes mediated the relationship between effortful control and SUD. Smaller volumes of the OFC and low effortful control during adolescence appear to be associated phenotypes that increase the risk of subsequent SUD. Further studies examining the temporal sequence of these risk factors are needed to fully understand this relationship. © 2016 S. Karger AG, Basel.

In this study, we evaluated predictors of resilience among 8- to 12-year-old children recruited from primarily low socioeconomic status neighborhoods, 117 of whom suffered from clinical levels of conduct problems and/or depression, and 63 of whom suffered from no significant symptoms. Tests of interactions were conducted between (a) paternal antisocial behavior and maternal depression and (b) several physiological indices of child temperament and emotionality in predicting (c) children’s conduct problems and depression. Both internalizing and externalizing outcomes among children were associated specifically with maternal melancholic depression, and not with nonmelancholic depression. In addition, low levels of respiratory sinus arrhythmia (RSA) among children conferred significant risk for depression, regardless of maternal melancholia, whereas high RSA offered partial protection. Furthermore, high levels of maternal melancholia conferred significant risk for child depression, regardless of paternal antisocial behavior, whereas low levels of maternal melancholia offered partial protection. Finally, low levels of electrodermal responding (EDR) conferred significant risk for conduct problems, regardless of paternal antisocial behavior, whereas high EDR offered partial protection. None of the identified protective factors offered complete immunity from psychopathology. These findings underscore the complexity of resilience and resilience-related processes, and suggest several potential avenues for future longitudinal research. PMID:17705899

A Translational Neuroscience Approach to Understanding the Development of Social Anxiety Disorder and its Pathophysiology

2014-01-01

This review brings together recent research from molecular, neural circuit, animal model, and human studies to understand the neurodevelopmental mechanisms underlying Social Anxiety Disorder (SAD). SAD is common, debilitating, and often leads to further psychopathology. Numerous studies demonstrate that extremely behaviorally inhibited and temperamentally anxious young children are at marked risk to develop SAD. Recent work in human and nonhuman primates has identified a distributed brain network that underlies early-life anxiety including: central nucleus of the amygdala, anterior hippocampus and orbitofrontal cortex. Moreover, studies in nonhuman primates demonstrate that alterations in this circuit are trait-like in that they are stable over time and across contexts. Importantly, the components of this circuit are differentially influenced by heritable and environmental factors and specific lesion studies demonstrate a causal role for multiple components of the circuit. Molecular studies in rodents and primates are pointing to disrupted neurodevelopmental and neuroplastic processes within critical components of the early-life dispositional anxiety neural circuit. The possibility of identifying an early-life at-risk phenotype, along with an understanding of its neurobiology, provides an unusual opportunity to conceptualize novel preventive intervention strategies aimed at reducing the suffering of anxious children and preventing them from developing further psychopathology.

2016-04-01

Various parenting behaviors (e.g., protection, intrusiveness, sensitivity) have been shown to impact young children's anxiety development, particularly for temperamentally inhibited children. These behaviors have sometimes predicted both increases and decreases in anxiety in inhibited children, suggesting that linear relations may not adequately model their influence. In the current study, we proposed the dimension of encouragement to approach novelty to characterize parenting behavior ranging from very little encouragement (i.e., protective behavior) to very strong encouragement (i.e., intrusiveness), with gentle encouragement residing in the middle. In a sample of 110 toddlers (48 female, 62 male) and their mothers, the linear and curvilinear effects of this parenting dimension were investigated in relation to change in child separation anxiety and shyness from age 2 to age 3. Inhibited temperament was also investigated as a moderator. Encouragement to approach novelty displayed the hypothesized curvilinear relation to change in separation anxiety, but not shyness, at extreme levels of inhibited temperament. Toddlers increased in separation anxiety when mothers' encouragement resided at either extreme end of the continuum, with lower child anxiety occurring when mothers displayed behavior closer to the middle of the continuum. Implications for the study of parenting outcomes for inhibited toddlers are discussed.

In a randomized controlled trial, the Observational Randomized Controlled Trial of Childhood Differential Susceptibility (ORCHIDS study), we tested whether observed parental affect and observed and reported parenting behavior are mechanisms of change underlying the effects of the behavioral parent training program the Incredible Years (IY). Furthermore, we tested whether some children are more susceptible to these change mechanisms because of their temperamental negative affectivity and/or serotonin transporter linked polymorphic region (5-HTTLPR) genotype. Participants were 387 Dutch children between 4 and 8 years of age (M age = 6.31, SD = 1.33; 55.3% boys) and their parents. Results showed that although IY was successful in improving parenting behavior and increasing parental positive affect, these effects did not explain the significant decreases in child externalizing problems. We therefore found no evidence for changes in parenting behavior or parental affect being the putative mechanisms of IY effectiveness. Furthermore, intervention effects on child externalizing behavior were not moderated by child negative affectivity or 5-HTTLPR genotype. However, child 5-HTTLPR genotype did moderate intervention effects on negative parenting behavior. This suggests that in research on behavioral parent training programs, "what works for which parents" might also be an important question.

Temperament and Attention as Core Mechanisms in the Early Emergence of Anxiety

2015-01-01

Anxiety is a pervasive, impairing, and early appearing form of psychopathology. Even when anxiety remits, children remain at a two- to threefold increased risk for the later emergence of a mood disorder. Therefore, it is imperative to identify and examine underlying mechanisms that may shape early emerging patterns of behavior that are associated with anxiety. One of the strongest and first visible risk factors is childhood temperament. In particular, children who are behaviorally inhibited or temperamentally shy are more likely to exhibit signs of anxiety by adolescence. However, not all shy children do so, despite the early risk. We know that attention mechanisms, particularly the presence of attention biases toward or away from threat, can play a critical role in the emergence of anxiety. The current chapter will bring together these separate lines of research to examine the ways in which attention can modulate the documented link between early temperament and later anxiety. In doing so, the chapter will highlight multiple levels of analysis that focus on the behavioral, cognitive, and neural mechanisms in the temperament-attention-anxiety network. The chapter will help identify both markers and mechanisms of risk, supporting future work aimed at improving theory and intervention by focusing on attention biases to environmental threat.

Little is known about how parenting might offset genetic risk to prevent the onset of child problems during toddlerhood. We used a prospective adoption design to separate genetic and environmental influences and test whether associations between structured parenting and toddler behavior problems were conditioned by genetic risk for psychopathology. The sample included 290 linked sets of adoptive families and birth mothers and 95 linked birth fathers. Genetic risk was assessed via birth mother and birth father psychopathology (anxiety, depression, antisociality, and drug use). Structured parenting was assessed via microsocial coding of adoptive mothers' behavior during a cleanup task. Toddler behavior problems were assessed with the Child Behavior Checklist. Controlling for temperamental risk at 9 months, there was an interaction between birth mother psychopathology and adoptive mothers' parenting on toddler behavior problems at 18 months. The interaction indicated two pathways to child problems: structured parenting was beneficial for toddlers at high genetic risk but was related to behavior problems for toddlers at low genetic risk. This crossover interaction pattern was replicated with birth father psychopathology as the index of genetic risk. The effects of structured parenting on toddler behavior problems varied as a function of genetic risk. Children at genetic risk might benefit from parenting interventions during toddlerhood that enhance structured parenting.

The present study investigated links between the observer-rated process of psychotherapy and 2 key psychotherapy relationship constructs (i.e., working alliance and attachment to the therapist) in the context of a brief, attachment-based, home-visiting, mother-infant intervention that aimed to promote later secure infant attachment. Additionally, links between observer ratings of intervener and mother contributions to process were examined. Participants included 85 economically stressed mothers of first-born, 5.5-month-old, temperamentally irritable infants. Therapists included 2 doctoral-level and 4 master's-level home visitors. Observer-rated therapist psychotherapy process variables (i.e., warmth, exploration, and negative attitude) were not linked to maternal ratings of working alliance. Therapist warmth, however, was positively associated with maternal ratings of security of attachment to the therapist, and therapist negative attitude was positively related to maternal ratings of preoccupied-merger attachment to the therapist. As expected, both therapist warmth and exploration were positively associated with both maternal participation and exploration. Therapist negative attitude was inversely related to maternal exploration, but not to maternal participation. Results support the idea that attention to the psychotherapy process and relationship may be important in the context of a brief home-visiting parenting intervention with a nonclinical sample.

Quasi-Dynamic Versus Fully-Dynamic Simulations of Slip Accumulation on Faults with Enhanced Dynamic Weakening

NASA Astrophysics Data System (ADS)

Lapusta, N.; Thomas, M.; Noda, H.; Avouac, J.

2012-12-01

Long-term simulations that incorporate both seismic events and aseismic slip are quite important for studies of earthquake physics but challenging computationally. To study long deformation histories, most simulation methods do not incorporate full inertial effects (wave propagation) during simulated earthquakes, using quasi-dynamic approximations instead. Here we compare the results of quasi-dynamic simulations to the fully dynamic ones for a range of problems to determine the applicability of the quasi-dynamic approach. Intuitively, the quasi-dynamic approach should do relatively well in problems where wave-mediated effects are relatively simple but should have substantially different (and hence wrong) response when the wave-mediated stress transfers dominate the character of the seismic events. This is exactly what we observe in our simulations. We consider a 2D model of a rate-and-state fault with a seismogenic (steady-state velocity-weakening) zone surrounded by creeping (steady-state velocity-strengthening) areas. If the seismogenic zone is described by the standard Dieterich-Ruina rate-and-state friction, the resulting earthquake sequences consist of relatively simple crack-like ruptures, and the inclusion of true wave-propagation effects mostly serves to concentrate stress more efficiently at the rupture front. Hence, in such models, rupture speeds and slip rates are significantly (several times) lower in the quasi-dynamic simulations compared to the fully dynamic ones, but the total slip, the crack-like nature of seismic events, and the overall pattern of earthquake sequences is comparable, consistently with prior studies. Such behavior can be classified as qualitatively similar but quantitatively different, and it motivates the popularity of the quasi-dynamic methods in simulations. However, the comparison changes dramatically once we consider a model with enhanced dynamic weakening in the seismogenic zone in the form of flash heating. In this case, the fully dynamic simulations produce seismic ruptures in the form of short-duration slip pulses, where the pulses form due to a combination of enhanced weakening and wave effects. The quasi-dynamic simulations in the same model produce completely different results, with large crack-like ruptures, different total slips, different rupture patterns, and different prestress state before large, model-spanning events. Such qualitative differences between the quasi-dynamic and fully-dynamic simulation should result in any model where inertial effects lead to qualitative differences, such as cases with supershear transition or fault with different materials on the two sides. We will present results on our current work on how the quasi-dynamic and fully dynamic simulations compare for the cases with heterogeneous fault properties.

Stress and personality.

Lecic-Tosevski, D; Vukovic, O; Stepanovic, J

Stress is an adaptation reaction of living organisms in response to internal or external threats to homeostasis. It is considered as a complex defence mechanism representing the final endpoint of numerous dynamic and interconnected factors of biological, psychological and social nature. Stress is not a simple, stimulus-response reaction, but the interaction between an individual and the environment, involving subjective perception and assessment of stressors, thus constituting a highly personalized process. Specific inherited characteristics, early experience in life, and particular, learned cognitive predispositions make individuals more or less susceptible to the effects of stressors. Resilience and vulnerability to stressors as well as intensity of stress response are greatly dependable on age, gender, intelligence, and numerous characteristics of personality, such as hardiness,locus of control, self-efficacy, self-esteem, optimism, hostility (component of type A personality)and type D traits (negative affectivity and social inhibition). To understand the relation between personality and stress, it is essential to recognize the impact of individual differences in the following four aspects: (1) choice or avoidance of environments that are associated with specific stressors, challenges or benefits, (2) way of interpreting a stressful situation and evaluating one's own abilities and capacities for proactive behaviour so as to confront or avoid it, (3) intensity of response to a stressor,and (4) coping strategies employed by the individual facing a stressful situation. Studies have recorded considerable consistency in coping strategies employed to confront stressful situations, independentlyof situational factors and in connection with permanent personality and temperamental traits,such as neuroticism, extraversion, sense of humour, persistence, fatalism, conscientiousness, andopenness to experience. Positive affect has been associated with positive reappraisal (reframing) ofstressful situations, goal-directed problem-focused coping, using spiritual or religious beliefs to seekcomfort, and infusion of meaning into the ordinary events of daily life in order to gain a psychologicaltime-out from distress. Characteristics of a resilient personality are: ability to cope in stressful situations,continuing engagement in activities, flexibility to unexpected changes in life, ability to seeksocial support, perceiving stress as a challenge - a chance for growth and development rather than athreat to life, taking care of one's body, living in harmony with nature, optimism and sense of humour,work and love, developing spiritualism and seeking true sense. The tolerance threshold is individual.However, even persons with mature and integrated personalities exposed to prolonged stress mayexperience failure of their adaptive capacities and psychological or somatic decompensation. Duringthe last years, Life Skills Education has become the focus of particular attention. Educational programsaim at developing the capacities for critical thinking, analyzing and problem-solving, buildingof self-confidence, confronting various negative pressures imposed by the environment, improvingself-assessment, developing communication and social adjustment skills, and gaining control overstressors and one's own affective and behavioral response. Finally, special programs for individualvulnerable population groups (teenagers, elderly persons, patients with AIDS, addictions, etc.) havebeen introduced so as to strengthen their ability to handle specific stressful situations.

The relationship between protein sequence, structure, and dynamics has been elusive. Here, we report a comprehensive analysis using an in-solution experimental approach to study how the conservation of tertiary structure correlates with protein dynamics. Hydrogen exchange measurements of eight processivity clamp proteins from different species revealed that, despite highly similar three-dimensional structures, clamp proteins display a wide range of dynamic behavior. Differences were apparent both for structurally similar domains within proteins and for corresponding domains of different proteins. Several of the clamps contained regions that underwent local unfolding with different half-lives. We also observed a conserved pattern of alternating dynamics of the α helices lining the inner pore of the clamps as well as a correlation between dynamics and the number of salt bridges in these α helices. Our observations reveal that tertiary structure and dynamics are not directly correlated and that primary structure plays an important role in dynamics. Copyright © 2014 Elsevier Ltd.

This paper presents the results of a study aimed at validating psychological questionnaires evaluating temperamental and personality features. It discusses their usefulness in diagnosing drivers' aptitude for safe driving and working as professional drivers. Three psychological questionnaires were validated: the Formal Characteristics of Behaviour - Temperament Inventory (FCB-TI), the Eysenck Personality Questionnaire - Revised and Short Scale (EPQ-R (S)) and the Impulsiveness Questionnaire (IVE). Three groups of drivers (n=246) aged 19-75 participated in the study. Group I (professional drivers; n=96) and Group II (nonprofessional drivers; n=75) had never been involved in road crashes, whereas Group III (nonprofessional drivers; n=75) were offenders involved in fatal injury road crashes. Criterion-related validity, Cronbach's alpha and Guttman split-half reliability coefficient were in assessing the psychometric properties of the questionnaires. There were some significant differences between Groups II and III for most traits. However, contrary to expectations, higher Emotional Reactivity, Perseveration and lower Endurance as well as higher Neuroticism, Impulsiveness and Venturesomeness were determined for Group II than for Group III. Additionally, the temperament and personality profile of Group II turned out to be less fitted to the profile of safe drivers than that of Group III, whose profile was actually similar to that of Group I. This seems to result from a high tendency for a positive self-presentation among Group I and Group III (a significantly higher result on the Lie scale in comparison with Group II). The results suggest that if psychological tests are to decide on whether a person may be a professional driver or may drive vehicles, the three questionnaires (FCB-TI, EPQ-R(S) and IVE) do not provide a valid diagnosis of professional drivers' aptitude because of drivers' high tendency for positive self-presentation. However, they can be used in job counselling and in screening high-risk drivers. Copyright © 2014 Elsevier Ltd. All rights reserved.

Beyond Behavioral Inhibition: A Computer Avatar Task Designed to Assess Behavioral Inhibition Extends to Harm Avoidance.

2017-01-01

Personality factors such as behavioral inhibition (BI), a temperamental tendency for avoidance in the face of unfamiliar situations, have been identified as risk factors for anxiety disorders. Personality factors are generally identified through self-report inventories. However, this tendency to avoid may affect the accuracy of these self-report inventories. Previously, a computer based task was developed in which the participant guides an on-screen "avatar" through a series of onscreen events; performance on the task could accurately predict participants' BI, measured by a standard paper and pencil questionnaire (Adult Measure of Behavioral Inhibition, or AMBI). Here, we sought to replicate this finding as well as compare performance on the avatar task to another measure related to BI, the harm avoidance (HA) scale of the Tridimensional Personality Questionnaire (TPQ). The TPQ includes HA scales as well as scales assessing reward dependence (RD), novelty seeking (NS) and persistence. One hundred and one undergraduates voluntarily completed the avatar task and the paper and pencil inventories in a counter-balanced order. Scores on the avatar task were strongly correlated with BI assessed via the AMBI questionnaire, which replicates prior findings. Females exhibited higher HA scores than males, but did not differ on scores on the avatar task. There was a strong positive relationship between scores on the avatar task and HA scores. One aspect of HA, fear of uncertainty was found to moderately mediate the relationship between AMBI scores and avatar scores. NS had a strong negative relationship with scores on the avatar task, but there was no significant relationship between RD and scores on the avatar task. These findings indicate the effectiveness of the avatar task as a behavioral alternative to self-report measures to assess avoidance. In addition, the use of computer based behavioral tasks are a viable alternative to paper and pencil self-report inventories, particularly when assessing anxiety and avoidance.

Although competing species are expected to exhibit compensatory dynamics (negative temporal covariation), empirical work has demonstrated that competitive communities often exhibit synchronous dynamics (positive temporal covariation). This has led to the suggestion that environmental forcing dominates species dynamics; however, synchronous and compensatory dynamics may appear at different length scales and/or at different times, making it challenging to identify their relative importance. We compiled 58 long-term datasets of zooplankton abundance in north-temperate and sub-tropical lakes and used wavelet analysis to quantify general patterns in the times and scales at which synchronous/compensatory dynamics dominated zooplankton communities in different regions and across the entire dataset. Synchronous dynamics were far more prevalent at all scales and times and were ubiquitous at the annual scale. Although we found compensatory dynamics in approximately 14% of all combinations of time period/scale/lake, there were no consistent scales or time periods during which compensatory dynamics were apparent across different regions. Our results suggest that the processes driving compensatory dynamics may be local in their extent, while those generating synchronous dynamics operate at much larger scales. This highlights an important gap in our understanding of the interaction between environmental and biotic forces that structure communities. © 2014 The Author(s) Published by the Royal Society.

The preliminary experimental results of Z-pinch dynamic hohlraums conducted on the Primary Test Stand (PTS) facility are presented herein. Six different types of dynamic hohlraums were used in order to study the influence of load parameters on radiation characteristics and implosion dynamics, including dynamic hohlraums driven by single and nested arrays with different array parameters and different foams. The PTS facility can deliver a current of 6-8 MA in the peak current and 60-70 ns in the 10%-90% rising time to dynamic hohlraum loads. A set of diagnostics monitor the implosion dynamics of plasmas, the evolution of shock waves in the foam and the axial/radial X-ray radiation, giving the key parameters characterizing the features of dynamic hohlraums, such as the trajectory and related velocity of shock waves, radiation temperature, and so on. The experimental results presented here put our future study on Z-pinch dynamic hohlraums on the PTS facility on a firm basis.

Nitrous oxide (N2O) is the third most important greenhouse gas and its terrestrial budget remains poorly constraint, with bottom up and top down estimates of country emissions often disagreeing by more than a factor of two. Whilst the measurements of the biosphere / atmosphere exchange of CO2 with micrometeorological methods is commonplace, emissions of CH4 and N2O are more commonly measured with enclosure techniques due to limitations in fast-response sensors with good signal-to-noise characteristics. Recent years have seen the development of a range of instruments based on optical spectroscopy. This started in the early 1990s with instruments based on lead salt lasers, which had temperamental long-term characteristics. More recent developments in quantum cascade lasers has lead to increasingly stable instruments, initially based on pulsed, later on continuous wave lasers. Within the context of the European FP7 Infrastructure Project InGOS ('Integrated non-CO2 Greenhouse gas Observing System'), we conducted an intercomparison of six fast response sensors for N2O: three more or less identical instruments based on off-axis Integrated Cavity Optical Spectrocopy (ICOS) (Los Gatos Research Inc.) and three instruments based on quantum cascade laser absorption spectrometry (Aerodyne Research Inc.): one older generation pulsed instrument (p-QCL) and two of the latest generation of compact continuous wave instruments (cw-QCL), operating at two different wavelengths. One of the ICOS instruments was operated with an inlet drier. In addition, the campaign was joined by a relaxed eddy-accumulation system linked to a FTIR spectrometer (Ecotech), a gradient system based on a home-built slower QCL (INRA Orleans) and a fast chamber system. Here we present the results of the study and a detailed examination of the various corrections and errors of the different instruments. Overall, with the exception of the older generation QCL, the average fluxes based on the different fast-response instruments agreed within +/- 7.4%, although fluxes were moderate. The cw-QCL systems showed somewhat better signal-to-noise characteristics and a lower flux detection limit than the ICOS analysers. Intriguingly, there seemed to be some minor differences between the ICOS instruments which showed cross sensitivities to CO to varying degree. Overall the study demonstrates, that, while not cheap, both the ICOS-based instruments and the cw-QCLs are suitable for the measurement of even moderate N2O fluxes.

On the number of different dynamics in Boolean networks with deterministic update schedules.

Aracena, J; Demongeot, J; Fanchon, E; Montalva, M

2013-04-01

Deterministic Boolean networks are a type of discrete dynamical systems widely used in the modeling of genetic networks. The dynamics of such systems is characterized by the local activation functions and the update schedule, i.e., the order in which the nodes are updated. In this paper, we address the problem of knowing the different dynamics of a Boolean network when the update schedule is changed. We begin by proving that the problem of the existence of a pair of update schedules with different dynamics is NP-complete. However, we show that certain structural properties of the interaction diagraph are sufficient for guaranteeing distinct dynamics of a network. In [1] the authors define equivalence classes which have the property that all the update schedules of a given class yield the same dynamics. In order to determine the dynamics associated to a network, we develop an algorithm to efficiently enumerate the above equivalence classes by selecting a representative update schedule for each class with a minimum number of blocks. Finally, we run this algorithm on the well known Arabidopsis thaliana network to determine the full spectrum of its different dynamics. Copyright © 2013 Elsevier Inc. All rights reserved.

Disconnecting structure and dynamics in glassy thin films

Sussman, Daniel M.; Cubuk, Ekin D.; Liu, Andrea J.

2017-01-01

Nanometrically thin glassy films depart strikingly from the behavior of their bulk counterparts. We investigate whether the dynamical differences between a bulk and thin film polymeric glass former can be understood by differences in local microscopic structure. Machine learning methods have shown that local structure can serve as the foundation for successful, predictive models of particle rearrangement dynamics in bulk systems. By contrast, in thin glassy films, we find that particles at the center of the film and those near the surface are structurally indistinguishable despite exhibiting very different dynamics. Next, we show that structure-independent processes, already present in bulk systems and demonstrably different from simple facilitated dynamics, are crucial for understanding glassy dynamics in thin films. Our analysis suggests a picture of glassy dynamics in which two dynamical processes coexist, with relative strengths that depend on the distance from an interface. One of these processes depends on local structure and is unchanged throughout most of the film, while the other is purely Arrhenius, does not depend on local structure, and is strongly enhanced near the free surface of a film.

Sun, Y.; Borland, Michael

Many different objectives and genetic algorithms have been proposed for storage ring nonlinear dynamics performance optimization. These optimization objectives include nonlinear chromaticities and driving/detuning terms, on-momentum and off-momentum dynamic acceptance, chromatic detuning, local momentum acceptance, variation of transverse invariant, Touschek lifetime, etc. In this paper, the effectiveness of several different optimization methods and objectives are compared for the nonlinear beam dynamics optimization of the Advanced Photon Source upgrade (APS-U) lattice. The optimized solutions from these different methods are preliminarily compared in terms of the dynamic acceptance, local momentum acceptance, chromatic detuning, and other performance measures.

Dynamics of Change and Change in Dynamics

PubMed Central

Boker, Steven M.; Staples, Angela D.; Hu, Yueqin

2017-01-01

A framework is presented for building and testing models of dynamic regulation by categorizing sources of differences between theories of dynamics. A distinction is made between the dynamics of change, i.e., how a system self–regulates on a short time scale, and change in dynamics, i.e., how those dynamics may themselves change over a longer time scale. In order to clarify the categories, models are first built to estimate individual differences in equilibrium value and equilibrium change. Next, models are presented in which there are individual differences in parameters of dynamics such as frequency of fluctuations, damping of fluctuations, and amplitude of fluctuations. Finally, models for within–person change in dynamics over time are proposed. Simulations demonstrating feasibility of these models are presented and OpenMx scripts for fitting these models have been made available in a downloadable archive along with scripts to simulate data so that a researcher may test a selected models’ feasibility within a chosen experimental design.

Evolution of the stellar mass function in multiple-population globular clusters

2018-05-01

We present the results of a survey of N-body simulations aimed at studying the effects of the long-term dynamical evolution on the stellar mass function (MF) of multiple stellar populations in globular clusters. Our simulations show that if first-(1G) and second-generation (2G) stars have the same initial MF (IMF), the global MFs of the two populations are affected similarly by dynamical evolution and no significant differences between the 1G and 2G MFs arise during the cluster's evolution. If the two populations have different IMFs, dynamical effects do not completely erase memory of the initial differences. Should observations find differences between the global 1G and 2G MFs, these would reveal the fingerprints of differences in their IMFs. Irrespective of whether the 1G and 2G populations have the same global IMF or not, dynamical effects can produce differences between the local (measured at various distances from the cluster centre) 1G and 2G MFs; these differences are a manifestation of the process of mass segregation in populations with different initial structural properties. In dynamically old and spatially mixed clusters, however, differences between the local 1G and 2G MFs can reveal differences between the 1G and 2G global MFs. In general, for clusters with any dynamical age, large differences between the local 1G and 2G MFs are more likely to be associated with differences in the global MF. Our study also reveals a dependence of the spatial mixing rate on the stellar mass, another dynamical consequence of the multiscale nature of multiple-population clusters.

Mood disorder history and personality assessment in premenstrual dysphoric disorder.

Menstrually related dysphoria is known to be associated with other affective disorders, notably major depressive disorder and puerperal depression. The relationship between premenstrual dysphoric disorder (PMDD) and maladaptive personality disorders and traits, however, is less established, at least in part because of the methodological and nosologic difficulties in the diagnosis of both PMDD and personality disorders. This study seeks to address this problem to elucidate the relationship between PMDD, other affective disturbances commonly experienced by women, and maladaptive personality. Axis I and II disorders were examined using standardized instruments and stringent diagnostic criteria (DSM-IV and the International Personality Disorders Examination) in 34 women with DSM-IV PMDD and 22 healthy women without severe premenstrual mood changes. Seventy-seven percent of the PMDD group had suffered from a past Axis I disorder in comparison with 17% of the control group. Two thirds of the parous women with PMDD had suffered from major depressive disorder in the puerperium. Personality disorder diagnoses were not highly represented in either group of women. The women with PMDD had significantly more obsessional personality traits (p < .001 ) but not absolute personality disorder diagnoses. Obsessional symptoms are known to cluster with the affective disorders and may reflect underlying temperamental and biological vulnerability. This study provides further evidence of the link between serotonergic dysregulation, personality vulnerability, and mood changes related to the female reproductive cycle.

Objective: Past research has associated childhood characteristics and experiences with alcohol use at single time points in adolescence. Other work has focused on drinking trajectories across adolescence but with risk factors typically no earlier than middle or high school. Similarly, although the connection between underage drinking and affiliation with deviant friends is well established, early risk factors for their covariation across adolescence are uncertain. The present study examines the influence of early individual and contextual factors on (a) trajectories across high school of per-occasion alcohol use and (b) the covariation of alcohol use and deviant friends over time. Method: In a longitudinal community sample (n = 374; 51% female), temperamental disinhibition, authoritarian and authoritative parenting, and parental alcohol use were assessed during childhood, and adolescents reported on alcohol use and affiliation with deviant friends in the spring of Grades 9, 10, 11, and 12. Results: Early parental alcohol use predicted the intercept of adolescent drinking. Subsequent patterns of adolescent alcohol use were predicted by sex and interactions of sex and childhood disinhibition with early authoritarian parenting. Additionally, childhood disinhibition interacted with parental alcohol use to moderate the covariation of drinking and deviant friends. Conclusions: These findings highlight early individual and contextual risk factors for alcohol use across high school, extending previous work and underscoring the importance of developmental approaches and longitudinal techniques for understanding patterns of growth in underage drinking.

Growth modeling was used to examine the developmental trajectory of infant temperamental fear with maternal fear and depressive symptoms as predictors of infant fearfulness and change in infant fear predicting toddler anxiety symptoms. In Study 1, a sample of 158 mothers reported their own depressive symptoms and fear when their children were 4 months of age and infant fearfulness at 4, 6, 8, 10, and 12 months. Maternal symptoms of depression predicted steeper increases in infant fearfulness over time (z = 2.06, p < .05), with high initial infant fear and steeper increases in fear (intercept, z = 2.32, p < .05, and slope, z = 1.88, p < .05) predicting more severe toddler anxiety symptoms. In Study 2, an independent sample of 134 mothers completed measures of maternal depression and fear when the infants were 4 months old, and standardized laboratory observations of infant fear were made at 8, 10, and 12 months. Consistent with Study 1, maternal depression accounted for change in fearfulness (z = 2.30, p < .05), with more frequent and more severe maternal symptoms leading to greater increases in infant fear and increases in fearfulness z = 2.08, p < .05) leading to more problematic toddler anxiety. The implications and contributions of these findings are discussed in terms of methodology, fear development, and developmental psychopathology. 2010 APA, all rights reserved

Positive parenting has been related both to lower cortisol reactivity and more adaptive temperament traits in children, whereas elevated cortisol reactivity may be related to maladaptive temperament traits, such as higher negative emotionality (NE) and lower positive emotionality (PE). However, no studies have examined whether hypothalamic-pituitary-adrenal axis activity, as measured by cortisol reactivity, moderates the effect of the quality of the parent-child relationship on changes in temperament in early childhood. In this study, 126 3-year olds were administered the Laboratory Temperament Assessment Battery (Lab-TAB; Goldsmith et al., 1995) as a measure of temperamental NE and PE. Salivary cortisol was collected from the child at 4 time points during this task. The primary parent and the child completed the Teaching Tasks battery (Egeland et al., 1995), from which the quality of the relationship was coded. At age 6, children completed the Lab-TAB again. From age 3 to 6, adjusting for age 3 PE or NE, a better quality relationship with their primary parent predicted decreases in NE for children with elevated cortisol reactivity and predicted increases in PE for children with low cortisol reactivity. Results have implications for our understanding of the interaction of biological stress systems and the parent-child relationship in the development of temperament in childhood. PMID:26689860

The delayed domestication of may be associated with their poor temperament and to date there is no published information on the temperament of the farmed Understanding of the temperament and selection program for its evaluation in a breeding herd is important not only for farming but also to other types of animal production. We investigated the temperament of ( = 17) raised in the tropics and determined its relationship with stress. A distance of 13.2 m was fixed for the measurement of flight times. hinds with rapid speed are considered temperamental. Each hind was earmarked for a crush test score between 1 and 5; 1 represents calm and 5 represents highly agitated . Stress was determined by measuring plasma cortisol using a cortisol RIA kit and live weight gain was determined by weighing the animals weekly. The hinds were aged using their date of birth records. We found a strong negative correlation between flight time, crush score, and plasma cortisol concentration ( < 0.05). Animals with very poor temperament have elevated plasma cortisol level and lower weight gain ( < 0.05). It was concluded that flight time, crush score, and plasma cortisol concentration could be used for selecting hinds based on temperament for the breeding herd. This method is quick and easy to implement on a farm; therefore, it remains the test choice for selecting animals based on temperament for the breeding herd.

Introduction The current study examined the relationships between parental depression, offspring depression, and offspring temperament among 203 offspring of parents with or without depression. The specific aim was to investigate how offspring difficult temperament affects frequency, severity, and duration of offspring major depressive episodes (MDEs). Methods As part of an ongoing multigenerational study assessing familial transmission of depression, offspring were assessed over a 20-year study period. Offspring temperament was assessed at baseline using the Dimensions of Temperament Survey and diagnostic interviews were conducted at each of the four waves using best estimate procedures. Results Difficult temperament predicted greater frequency of lifetime MDEs. Parental depression moderated the relationship between offspring difficult temperament and severity of MDEs, such that difficult temperament was associated with increased severity ratings among high-risk, but not low-risk offspring. Dimensional analysis revealed that lower rhythmicity and adaptability were associated with greater number of lifetime MDEs, while higher inattention/distractibility was associated with shorter duration of MDEs. Discussion Certain limitations must be noted, namely the self-report nature of temperament data and the relatively small sample size drawn from a clinical and predominantly Caucasian and Christian sample. Notwithstanding these limitations, our results suggest that the clinical presentation of major depression may reflect temperamental profiles and should be considered in diagnostic and treatment settings.

[Bipolar disorder: inter-episode symptoms].

PubMed

Azorin, J-M

2012-12-01

The importance of inter-episode symptoms in bipolar disorder can be traced back to the middle of the 19th century, at a time when the two fathers of the concept in France, Falret and Baillarger were opposed on the issue as to whether the presence of free intervals between the episodes had to be part or not of the disease's definition. Modern studies have reported rates between 50 and 68% for those symptoms which refer to subsyndromal manifestations present between affective episodes but that do not meet the required criteria for episodes definition. These manifestations comprise residual symptoms, prodromes, axis I comorbid psychiatric disorders, side effects of treatment, temperamental features, and comorbidity with personality disorders. Inter- episodes symptoms represent a risk factor for the occurrence of relapses and recurrences and are usually associated with impairments in functioning in almost all domains of psychosocial and family life. As they are easy to miss, it is important in clinical practice, to draw the attention of clinicians, patients and relatives to the role they have in the course of the illness. As far as their management, it may be crucial to achieve a full remission of the episodes, using adequate dosages of psychotropic drugs. Residual symptoms, prodromes as well as other inter-episode symptoms may respond to strategies based on cognitive-behaviour therapy, and/or psychoeducation. Copyright © 2012 L’Encéphale.

Stressful life events increase the probability of depressive problems in early adolescence. Several genetic and environmental risk factors may change individual sensitivity to the depressogenic effect of these events. We examined modification by parental depression and gender, and mediation of the former by temperament and family environment. Data were collected as part of a longitudinal cohort study of (pre)adolescents (n = 2127). During the first assessment wave at approximately age 11, we assessed parental depression, family functioning, perceived parenting behaviours, and temperamental frustration and fearfulness. At the second wave, about two and a half years later, stressful life events between the first and second assessment were assessed. Depressive problems were measured at both waves. Adolescents with parents who had a (lifetime) depressive episode were more sensitive to the depressogenic effect of stressful events than adolescents without depressed parents. Furthermore, girls are more sensitive to these effects than boys. The modifying effect of parental depression was not mediated by temperament, family functioning and perceived parenting. Life events were assessed without consideration of contextual information. Depressive problems were measured by questionnaires that did not directly represent DSM-IV criteria. The measure of parental depression was unspecific regarding severity and timing of depressive episodes. The results suggest that gender and parental depression are associated with increased sensitivity to depression after experiencing stressful life events during adolescence.

Objective Although most people will experience a traumatic event, only some will develop significant psychological symptoms in the aftermath. In the current study, we utilize a preexisting longitudinal study located in Long Island to examine the impact of Hurricane Sandy on internalizing symptoms in a large sample of children. We focused on temperamental fear and a biomarker of risk for anxiety, the error-related negativity (ERN). The ERN is a negative deflection in the event-related potential (ERP) occurring when individuals make mistakes and is increased in anxious individuals. Method The final sample consisted of 223 children who had undergone an observational assessment of fear at age 3 and an electroencephalogram assessment of the ERN at age 6. At the age 9 assessment, internalizing symptoms were assessed, and then again after the hurricane (approximately 65 weeks later). Results A significant three-way interaction between fearfulness, hurricane stressors, and the ERN in predicting post-hurricane increases in internalizing symptoms suggested that children who were high in fear at age 3 and experienced elevated hurricane stressors were characterized by subsequent increases in internalizing symptoms, but only when they were also characterized by an increased ERN at age 6. Conclusion These findings support a diathesis-stress model, suggesting that early temperament and pre-stressor biological markers confer risk for increased psychological symptoms following environmental stressors.

The purpose of the present study was to investigate whether infant temperament and previous feeding history were associated with infants’ acceptance and rejection of a novel food at 12 months of age. Mother–infant dyads (n = 89) were video-recorded during a novel food (hummus, cottage cheese) feeding task. Infants’ reactions (acceptance and rejection behaviors) and maternal responsiveness and affect during the interaction were coded from the recordings by teams of coders. Mothers reported on their infants’ temperamental approach via the Infant Behavior Questionnaire-Revised (IBQ-R) and their infants’ feeding history (previous exposure to solid foods and exclusive breastfeeding). Regression analyses revealed that infants rated lower on approach showed less acceptance of the first offer of novel food than infants rated higher on approach. Additionally, low approach infants who were previously exposed to a greater number of solid foods showed fewer rejection behaviors in response to the later offers of food. Exclusive breastfeeding for 4 months did not appear to have an effect on acceptance or rejection. Finally, greater maternal responsiveness was related to the infants’ acceptance of the new food whereas lower maternal responsiveness was associated with rejection of the novel food. These results suggest that the acceptance and rejection of new foods by infants is dependent upon their temperament and previous exposure to solid foods, as well as the manner in which mothers present the novel food.

Considerable research exists documenting the relationship between maternal mood disorders, primarily major depressive disorder (MDD), and a variety of negative child outcomes. By contrast, research exploring the reverse pathway whereby child traits are associated with later maternal mood disorders is much more limited. We examined whether young children’s temperament and psychopathology predicted maternal mood disorders approximately 6 years later. Child temperament and symptoms were assessed at age three using semi-structured diagnostic interviews and parent-report inventories. Maternal psychopathology was assessed with semi-structured interviews when children were three and nine years old. Mothers also reported on their marital satisfaction when children were three and six years old. Child temperamental negative affectivity (NA), depressive symptoms, and externalizing behavior problems significantly predicted maternal mood disorders over and above prior maternal mood, anxiety, and substance disorders. The link between children’s early externalizing symptoms and maternal mood disorders 6 years later was mediated by maternal marital satisfaction 3 years after the initial assessment. These findings suggest that early child temperament and psychopathology contribute to risk for later maternal mood disorders both directly and through their impact on the marital system. Research indicates that effective treatment of maternal depression is associated with positive outcomes for children; however, this study suggests that treating early child problems may mitigate the risk of later maternal psychopathology.

Affective temperaments are the subclinical manifestations or phenotypes of mood states and hypothetically represent one healthy end of the mood disorder spectrum. However, there is a scarcity of studies investigating the neurobiological basis of affective temperaments. One fundamental aspect of temperament is the behavioral reactivity to environmental stimuli, which can be effectively evaluated by use of cognitive event-related potentials (ERPs) reflecting the diversity of information processing. The aim of the present study is to explore the associations between P300 and the affective temperamental traits in healthy individuals. We recorded the P300 ERP waves using an auditory oddball paradigm in 50 medical student volunteers (23 females, 27 males). Participants' affective temperaments were evaluated using the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego-auto questionnaire version (TEMPS-A). In bivariate analyses, depressive temperament score was significantly correlated with P300 latency ( r s = 0.37, P < .01). In a multiple linear regression analysis, P300 latency showed a significant positive correlation with scores of depressive temperament (β = 0.40, P < .01) and a significant negative one with scores of cyclothymic temperament (β = -0.29, P = .03). Affective temperament scores were not associated with P300 amplitude and reaction times. These results indicate that affective temperaments are related to information processing in the brain. Depressive temperament may be characterized by decreased physiological arousal and slower information processing, while the opposite was observed for cyclothymic temperament.

Depression is characterized by low positive emotionality (PE) and high negative emotionality (NE), as well as asymmetries in resting electroencephalography (EEG) alpha power. Moreover, frontal asymmetry has itself been linked to PE, NE, and related constructs. However, little is known about associations of temperamental PE and NE with resting EEG asymmetries in young children and whether this association changes as a function of development. In a longitudinal study of 254 three-year old children, we assessed PE and NE at age 3 using a standard laboratory observation procedure. Frontal EEG asymmetries were assessed at age 3 and three years later at age 6. We observed a significant three-way interaction of preschool PE and NE and age at assessment for asymmetry at F3-F4 electrode sites, such that children with both low PE and high NE developed a pattern of increasingly lower relative left-frontal cortical activity over time. In addition, F7-F8 asymmetry was predicted by a PE by time interaction, such that the frontal asymmetry in children with high PE virtually disappeared by age 6. Overall, these findings suggest that early temperament is associated with developmental changes in frontal asymmetry, and that the combination of low PE and high NE predicts the development of the pattern of frontal symmetry that is associated with depression.

A Tour Through Shape Dynamic Black Holes

NASA Astrophysics Data System (ADS)

Herczeg, Gabriel

Shape dynamics is a classical theory of gravity which agrees with general relativity in many important cases, but possesses different gauge symmetries and constraints. Rather than spacetime diffeomorphism invariance, shape dynamics takes spatial diffeomorphism invariance and spatial Weyl invariance as the fundamental gauge symmetries associated with the gravitational field. Despite these differences, shape dynamics and general relativity generically predict the same dynamics--there exist gauge-fixings of each theory that ensure agreement with the other. However, these gauge-fixing conditions are not necessarily globally well-defined and it is therefore possible to find solutions of the shape dynamics equations of motion that agree with general relativity on some open neighborhoods, but which have different global structures. In particular, the black hole solutions of the two theories disagree globally. Understanding these novel "shape dynamic black holes" is the primary goal of this thesis.

This paper investigates hybrid function projective synchronization in complex dynamical networks. When the complex dynamical networks could be synchronized up to an equilibrium or periodic orbit, a hybrid feedback controller is designed to realize the different component of vector of node could be synchronized up to different desired scaling function in complex dynamical networks with time delay. Hybrid function projective synchronization (HFPS) in complex dynamical networks with constant delay and HFPS in complex dynamical networks with time-varying coupling delay are researched, respectively. Finally, the numerical simulations show the effectiveness of theoretical analysis.

Dynamic change in psychotherapy, as measured by theory-related or mode-specific instruments, have been criticized for being too intercorrelated with symptomatic change measures. In this study, long-term changes after brief dynamic psychotherapy were studied in 45 moderately disturbed neurotic patients by a reliable outcome battery. The factor structure of all the change variables suggested that they tapped 2 distinct and stable sources of variance: dynamic and symptomatic change. The categories of overall dynamic change were different from categories of change on the Global Assessment Scale. A small systematic difference was found between the categories of overall dynamic change and the categories of target complaints change also, due to false solutions of dynamic conflicts.

The generation of action potentials (APs) is a key process in the operation of nerve cells and the communication between neurons. Action potentials in mammalian central neurons are characterized by an exceptionally fast onset dynamics, which differs from the typically slow and gradual onset dynamics seen in identified snail neurons. Here we describe a novel method of analysis which provides a quantitative measure of the onset dynamics of action potentials. This method captures the difference between the fast, step-like onset of APs in rat neocortical neurons and the gradual, exponential-like AP onset in identified snail neurons. The quantitative measure of the AP onset dynamics, provided by the method, allows us to perform quantitative analyses of factors influencing the dynamics.

Globular star clusters that formed at the same cosmic time may have evolved rather differently from the dynamical point of view (because that evolution depends on the internal environment) through a variety of processes that tend progressively to segregate stars more massive than the average towards the cluster centre. Therefore clusters with the same chronological age may have reached quite different stages of their dynamical history (that is, they may have different 'dynamical ages'). Blue straggler stars have masses greater than those at the turn-off point on the main sequence and therefore must be the result of either a collision or a mass-transfer event. Because they are among the most massive and luminous objects in old clusters, they can be used as test particles with which to probe dynamical evolution. Here we report that globular clusters can be grouped into a few distinct families on the basis of the radial distribution of blue stragglers. This grouping corresponds well to an effective ranking of the dynamical stage reached by stellar systems, thereby permitting a direct measure of the cluster dynamical age purely from observed properties.

Dynamic characteristics of a pump-turbine during hydraulic transients of a model pumped-storage system: 3D CFD simulation

The runaway process in a model pumped-storage system was simulated for analyzing the dynamic characteristics of a pump-turbine. The simulation was adopted by coupling 1D (One Dimensional) pipeline MOC (Method of Characteristics) equations with a 3D (Three Dimensional) pump-turbine CFD (Computational Fluid Dynamics) model, in which the water hammer wave in the 3D zone was defined by giving a pressure dependent density. We found from the results that the dynamic performances of the pump-turbine do not coincide with the static operating points, especially in the S-shaped characteristics region, where the dynamic trajectories follow ring-shaped curves. Specifically, the transient operating points with the same Q11 and M11 in different moving directions of the dynamic trajectories give different n11. The main reason of this phenomenon is that the transient flow patterns inside the pump-turbine are influenced by the ones in the previous time step, which leads to different flow patterns between the points with the same Q11 and M11 in different moving directions of the dynamic trajectories.

But, understanding the atomistic details of protein dynamics and the role of hydration water remains rather limited.

Internal protein dynamics spread overmore » a wide time range fromfaster than picosecond to longer than microseconds. We suggest that the structural relaxation in hydrated proteins appears on the microsecond time scale, while faster processes present mostly motion of side groups and some domains. Hydration water plays a crucial role in protein dynamics on all time scales. It controls the coupled protein-hydration water relaxation on 10 100 ps time scale. Our process defines the friction for slower protein dynamics.

This paper presents state-of-the art within advanced vehicle dynamics of heavy trucks with the perspective of road safety. The most common accidents with heavy trucks involved are truck against passenger cars. Safety critical situations are for example loss of control (such as rollover and lateral stability) and a majority of these occur during speed when cornering. Other critical situations are avoidance manoeuvre and road edge recovery. The dynamic behaviour of heavy trucks have significant differences compared to passenger cars and as a consequence, successful application of vehicle dynamic functions for enhanced safety of trucks might differ from the functions in passenger cars. Here, the differences between vehicle dynamics of heavy trucks and passenger cars are clarified. Advanced vehicle dynamics solutions with the perspective of road safety of trucks are presented, beginning with the topic vehicle stability, followed by the steering system, the braking system and driver assistance systems that differ in some way from that of passenger cars as well.

To compare estimation of glomerular filtration rate determined via conventional methods (ie, scintigraphy and plasma clearance of technetium Tc 99m pentetate) and dynamic single-slice computed tomography (CT). 8 healthy adult cats. Scintigraphy, plasma clearance testing, and dynamic CT were performed on each cat on the same day; order of examinations was randomized. Separate observers performed GFR calculations for scintigraphy, plasma clearance testing, or dynamic CT. Methods were compared via Bland-Altman plots and considered interchangeable and acceptable when the 95% limits of agreement (mean difference between methods ± 1.96 SD of the differences) were ≤ 0.7 mL/min/kg. Global GFR differed < 0.7 mL/min/kg in 5 of 8 cats when comparing plasma clearance testing and dynamic CT; the limits of agreement were 1.4 and -1.7 mL/min/kg. The mean ± SD difference was -0.2 ± 0.8 mL/min/kg, and the maximum difference was 1.6 mL/min/kg. The mean ± SD difference (absolute value) for percentage filtration by individual kidneys was 2.4 ± 10.5% when comparing scintigraphy and dynamic CT; the maximum difference was 20%, and the limits of agreement were 18% and 23% (absolute value). GFR estimation via dynamic CT exceeded the definition for acceptable clinical use, compared with results for conventional methods, which was likely attributable to sample size and preventable technical complications. Because 5 of 8 cats had comparable values between methods, further investigation of dynamic CT in a larger sample population with a wide range of GFR values should be performed.

The dynamical fusion process of 48Ca + 144Sm with different impact parameters near barrier is studied by an extended quantum molecular dynamics (EQMD) model, where width of wavepacket is dynamically treated based on variational principle. The time evolution of different energy components such as potential energy, kinetic energy, Coulomb energy and Pauli potential are analyzed when dynamical or fixed width is assumed in calculation. It is found that the dynamical wavepacket width can enhance the dissipation of incident energy and the fluctuations, which are important to form compound nuclei. Moreover, we compare the fusion barrier dependence on the incident energy when it is determined by both dynamical and fixed wavepacket width.

Effects of dynamical grouping on cooperation in N-person evolutionary snowdrift game

A population typically consists of agents that continually distribute themselves into different groups at different times. This dynamic grouping has recently been shown to be essential in explaining many features observed in human activities including social, economic, and military activities. We study the effects of dynamic grouping on the level of cooperation in a modified evolutionary N-person snowdrift game. Due to the formation of dynamical groups, the competition takes place in groups of different sizes at different times and players of different strategies are mixed by the grouping dynamics. It is found that the level of cooperation is greatly enhanced by the dynamic grouping of agents, when compared with a static population of the same size. As a parameter β, which characterizes the relative importance of the reward and cost, increases, the fraction of cooperative players fC increases and it is possible to achieve a fully cooperative state. Analytically, we present a dynamical equation that incorporates the effects of the competing game and group size distribution. The distribution of cooperators in different groups is assumed to be a binomial distribution, which is confirmed by simulations. Results from the analytic equation are in good agreement with numerical results from simulations. We also present detailed simulation results of fC over the parameter space spanned by the probabilities of group coalescence νm and group fragmentation νp in the grouping dynamics. A high νm and low νp promotes cooperation, and a favorable reward characterized by a high β would lead to a fully cooperative state.

Dynamical heterogeneities of cold 2D Yukawa liquids

Dynamical heterogeneities of 2D liquid dusty plasmas at different temperatures are investigated systematically using Langevin dynamical simulations. From the simulated trajectories, various heterogeneity measures have been calculated, such as the distance matrix, the averaged squared displacement, the non-Gaussian parameter, and the four-point susceptibility. It is found that, for 2D Yukawa liquids, both spatial and temporal heterogeneities in dynamics are more severe at a lower temperature near the melting point. For various temperatures, the calculated non-Gaussian parameter of 2D Yukawa liquids contains two peaks at different times, indicating the most heterogeneous dynamics, which are attributed to the transition of different motions and the α relaxation time, respectively. In the diffusive motion, the most heterogeneous dynamics for a colder Yukawa liquid happen more slowly, as indicated by both the non-Gaussian parameter and the four-point susceptibility.

Concurrence of dynamical phase transitions at finite temperature in the fully connected transverse-field Ising model

We construct the finite-temperature dynamical phase diagram of the fully connected transverse-field Ising model from the vantage point of two disparate concepts of dynamical criticality. An analytical derivation of the classical dynamics and exact diagonalization simulations are used to study the dynamics after a quantum quench in the system prepared in a thermal equilibrium state. The different dynamical phases characterized by the type of nonanalyticities that emerge in an appropriately defined Loschmidt-echo return rate directly correspond to the dynamical phases determined by the spontaneous breaking of Z2 symmetry in the long-time steady state. The dynamical phase diagram is qualitatively different depending on whether the initial thermal state is ferromagnetic or paramagnetic. Whereas the former leads to a dynamical phase diagram that can be directly related to its equilibrium counterpart, the latter gives rise to a divergent dynamical critical temperature at vanishing final transverse-field strength.

The field of study of complex systems considers that the dynamics of complex systems are founded on universal principles that may be used to describe a great variety of scientific and technological approaches of different types of natural, artificial, and social systems. Several authors have suggested that earthquake dynamics and the dynamics of economic (financial) systems can be analyzed within similar mathematical frameworks. We apply concepts of the nonextensive statistical physics, on time-series data of observable manifestations of the underlying complex processes ending up with these different extreme events, in order to support the suggestion that a dynamical analogy exists between a financial crisis (in the form of share or index price collapse) and a single earthquake. We also investigate the existence of such an analogy by means of scale-free statistics (the Gutenberg-Richter distribution of event sizes). We show that the populations of: (i) fracto-electromagnetic events rooted in the activation of a single fault, emerging prior to a significant earthquake, (ii) the trade volume events of different shares/economic indices, prior to a collapse, and (iii) the price fluctuation (considered as the difference of maximum minus minimum price within a day) events of different shares/economic indices, prior to a collapse, follow both the traditional Gutenberg-Richter law as well as a nonextensive model for earthquake dynamics, with similar parameter values. The obtained results imply the existence of a dynamic analogy between earthquakes and economic crises, which moreover follow the dynamics of seizures, magnetic storms and solar flares.

The dynamics of insulin secretion stimulated by repaglinide, a glinide, and the combinatorial effects of repaglinide and incretin were investigated. At 4.4 mM glucose, repaglinide induced insulin secretion with a gradually increasing first phase, showing different dynamics from that induced by glimepiride, a sulfonylurea. In the presence of glucagon-like peptide-1 (GLP-1), insulin secretion by repaglinide was augmented significantly but to lesser extent and showed different dynamics from that by glimepiride. At 4.4 mM glucose, the intracellular Ca 2+ level was gradually increased by repaglinide alone or repaglinide plus GLP-1, which differs from the Ca 2+ dynamics by glimepiride alone or glimepiride plus GLP-1, suggesting that the difference in Ca 2+ dynamics contributes to the difference in the dynamics of insulin secretion. At a higher concentration (8.8 mM) of glucose, the dynamics of insulin secretion stimulated by repaglinide was similar to that by glimepiride. Combination of repaglinide and GLP-1 significantly augmented insulin secretion, the amount of which was comparable to that by the combination of glimepiride and GLP-1. The Ca 2+ dynamics was similar for repaglinide and glimepiride at 8.8 mM glucose. Our data indicate that repaglinide has characteristic properties in its effects on the dynamics of insulin secretion and intracellular Ca 2+ and that the combination of repaglinide and GLP-1 stimulates insulin secretion more effectively than the combination of glimepiride and GLP-1 at a high concentration of glucose, providing a basis for its use in clinical settings.

It is interesting and of significant importance to investigate how network structures co-evolve with opinions. In this article, we show that, a simple model integrating consensus formation, link rewiring, and opinion change allows complex system dynamics to emerge, driving the system into a dynamic equilibrium with the co-existence of diversified opinions. Specifically, similar opinion holders may form into communities yet with no strict community consensus; and rather than being separated into disconnected communities, different communities are connected by a non-trivial proportion of inter-community links. More importantly, we show that the complex dynamics may lead to different numbers of communities at the steady state with a given tolerance between different opinion holders. We construct a framework for theoretically analyzing the co-evolution process. Theoretical analysis and extensive simulation results reveal some useful insights into the complex co-evolution process, including the formation of dynamic equilibrium, the transition between different steady states with different numbers of communities, and the dynamics between opinion distribution and network modularity.

Exploring the Internal Dynamics of Globular ClustersThe formation histories and structural properties of globular clusters are imprinted on their internal dynamics. Energy equipartition results in velocity differences for stars of different mass, and leads to mass segregation, which results in different spatial distributions for stars of different mass. Intermediate-mass black holes significantly increase the velocity dispersions at the centres of clusters. By combining accurate measurements of their internal kinematics with state-of-the-art dynamical models, we can characterise both the velocity dispersion and mass profiles of clusters, tease apart the different effects, and understand how clusters may have formed and evolved.Using proper motions from the Hubble Space Telescope Proper Motion (HSTPROMO) Collaboration for a set of 22 Milky Way globular clusters, and our discrete dynamical modelling techniques designed to work with large, high-quality datasets, we are studying a variety of internal cluster properties. We will present the results of theoretical work on simulated clusters that demonstrates the efficacy of our approach, and preliminary results from application to real clusters.

In this review paper, we will present different data-driven dimension reduction techniques for dynamical systems that are based on transfer operator theory as well as methods to approximate transfer operators and their eigenvalues, eigenfunctions, and eigenmodes. The goal is to point out similarities and differences between methods developed independently by the dynamical systems, fluid dynamics, and molecular dynamics communities such as time-lagged independent component analysis, dynamic mode decomposition, and their respective generalizations. As a result, extensions and best practices developed for one particular method can be carried over to other related methods.
