    Rather than being a static, species specific trait, reproductive behavior in female amphibians is variable within an individual during the breeding season when females are capable of reproductive activity. Changes in receptivity coincide with changes in circulating estrogen. Estrogen is highest at the point when females are ready to choose a male and lay eggs. At this time female receptivity (her probability of responding to a male vocal signal) is highest and her selectivity among conspecific calls (measured by her probability of responding to a degraded or otherwise usually unattractive male signal) is lowest. These changes occur even though females retain the ability to discriminate different acoustic characteristics of various conspecific calls. After releasing her eggs, female amphibians quickly become less receptive and more choosy in terms of their responses to male sexual advertisement signals. Male vocal signals stimulate both behavior and estrogen changes in amphibian females making mating more probable. The changes in female reproductive behavior are the same as those generally accepted as indicative of a change in female sexual arousal leading to copulation. They are situationally triggered, gated by interactions with males, and decline with the consummation of sexual reproduction with a chosen male. The changes can be triggered by either internal physiological state or by the presence of stimuli presented by males, and the same stimuli change both behavior and physiological (endocrine) state in such a way as to make acceptance of a male more likely. Thus amphibian females demonstrate many of the same general characteristics of changing female sexual state that in mammals indicate sexual arousal. PMID:20816968

    Introduction Theoretically, the physiological response to stress should inhibit the sexual response. This has been demonstrated experimentally in animal models, and correlationally in studies of human reproduction. It is reasonable to expect, then, that the stress response would be blunted during sexual arousal, and several researchers have found a pattern of decreasing cortisol during sexual arousal. Aim In the present study, we explored individual differences in women’s cortisol response to sexual arousal in a laboratory setting. We also examined how cortisol response in the laboratory related to a validated measure of sexual arousal functioning in real life. Main Outcome Measures Cortisol levels were measured in saliva via enzyme immunoassay. Subjective arousal was measured by a self-report questionnaire, and genital arousal was measured by a vaginal photoplethysmograph. Methods Subjective and physiological responses to an erotic film were assessed in 30 women. Saliva samples were taken at baseline and following the film. Results The majority of women (N = 20) showed a decrease in cortisol; nine women showed an increase in response to an erotic film. The women who showed an increase in cortisol had lower scores on the Arousal, Desire, and Satisfaction domains of the Female Sexual Function Index. Genital arousal in the laboratory was not related to cortisol change. Conclusions Women who show an increase in cortisol in response to sexual stimuli in the laboratory have lower levels of functioning in certain areas of their sexual life compared with women who show a decrease in cortisol. Stress related to sexual performance may interfere with sexual arousal. PMID:18624961

    Unlike members of other species that are genetically wired to be attracted to their sexual partners, humans learn the cues that guide them in choosing their sexual partners and that trigger sexual arousal. Genetically wired mechanisms must be directing the acquisition of those cues and organizing them in information structures that underlie human sexual behavior. Individual sexuality is a combination of the genetic mechanisms and information learned through personal experiences. This article focuses on the roots of human sexuality - on genetically embedded mechanisms, common to all humans, around which the wide variety of sexual behaviors is built. It proposes a model that defines the basic mechanisms and their role in developing individual sexuality. It is suggested that three brain areas host the roots of human sexuality: the auditory area, which provides stimuli that serve as cues for the identification of a mate; an emotional area, which provides cues for emotional arousal; and a corporal area, which controls the physiological expressions of arousal. The amygdala is a main candidate for the emotional area, and the hypothalamus for the corporal area, but other areas may also provide those inputs. Experimental observations that support this model are discussed, and an outline of additional experiments for validating the model is proposed. If validated, the model would provide knowledge that fills a gap in the understanding of human sexuality - knowledge that would benefit individuals, the medical profession, and society as a whole.

    Previous research suggested that disgust may interfere with healthy sexual functioning by demonstrating that women with sexual pain disorders are characterized by heightened disgust propensity, relatively strong (physiological and subjective) disgust responses when exposed to sexual stimuli, and relatively strong automatic sex-disgust memory associations. To broaden the understanding of the relationship between sex and disgust, Study 1 tested the relationship between trait disgust and sexual functioning in both men (N = 109) and women (N = 187), and showed that specifically for women both relatively high disgust propensity and high sensitivity were related to lower sexual functioning. Study 2 focused on healthy young adults (N = 19 men and N = 24 women), and tested the relationship between trait disgust and automatic sex-disgust associations as well as the predictive value of trait disgust propensity for participants' level of sexual arousal while watching an erotic video. Participants completed a single-target Implicit Association Task and self-report measures of trait disgust propensity, disgust sensitivity, and sexual functioning. Furthermore, genital and subjective sexual arousal was measured, while participants were watching neutral and erotic video clips. Women showed stronger sex-disgust associations and reported higher disgust propensity than men. Overall, indices of trait disgust and sex-disgust associations were not strongly associated with sexual functioning or sexual arousability. Unexpectedly, specifically in men, high levels of trait disgust sensitivity predicted higher levels of genital and subjective sexual arousal. Overall, no strong evidence was found to support the view that, among young adults without sexual difficulties, high trait disgust or relatively strong automatic sex-disgust associations are associated with low sexual functioning and low sexual arousal.

    Conditioning of sexual arousal has been demonstrated in several species from fish to humans but has not been demonstrated in nonhuman primates. Controversy exists over whether nonhuman primates produce pheromones that arouse sexual behavior. Although common marmosets copulate throughout the ovarian cycle and during pregnancy, males exhibit behavioral signs of arousal, demonstrate increased neural activation of anterior hypothalamus and medial preoptic area, and have an increase in serum testosterone after exposure to odors of novel ovulating females suggestive of a sexually arousing pheromone. Males also have increased androgens prior to their mate's ovulation. However, males presented with odors of ovulating females demonstrate activation of many other brain areas associated with motivation, memory, and decision making. In this study, we demonstrate that male marmosets can be conditioned to a novel, arbitrary odor (lemon) with observation of erections, and increased exploration of the location where they previously experienced a receptive female, and increased scratching in post-conditioning test without a female present. This conditioned response was demonstrated up to a week after the end of conditioning trials, a much longer lasting effect of conditioning than reported in studies of other species. These results further suggest that odors of ovulating females are not pheromones, strictly speaking and that marmoset males may learn specific characteristics of odors of females providing a possible basis for mate identification.

    The fetish objects in these case histories were unique enough, and the attraction to the objects strong enough, that the individuals could clearly track their interest from early childhood through adulthood. It is much easier to retrieve remote, explicit memories, such as events (eg, a party where balloons popped) or playing with objects, than to recall the process of sexual development with no distinct markers in the individual's history. Because these distinct experiences predated identified sexuality, became a focus of attention for the individual, and then were incorporated into the individual's sexual interests and masturbatory fantasies, it was possible to accurately track the patterns of sexual arousal. We were also able to clearly identify how these men attempted to blend their deviant interests into sexual relationships with partners and the consequences of their efforts. If we are to understand how sexual interests develop, a number of obstacles need to be overcome. Sexual interest has to be openly discussed. Parents need to appreciate how the early sexual interests of their children can go awry, contaminate their adult relationships, and lead to problematic lives. Researchers need a means of understanding how to communicate with children about their earliest interests, sexual interests, and sexual behaviors in a nonjudgmental manner. Until then, tracking unusual interests that lead to erotic interests is the first step in the overall process of understanding how sexual interest develops and is assimilated, either successfully or unsuccessfully, into an individual's adult sexual life.

    Disgust, a negative emotion which evokes strong behavioral avoidance tendencies, has been associated with sexual dysfunction. Recently, it was postulated that healthy sexual functioning requires a balance between excitatory (increased sexual arousal) and inhibitory processes (lowered disgust levels). This suggests that amplification of excitatory processes (like sexual arousal) could be a valuable addition to treatments for affect-based sexual dysfunctions. The major aim of the present study was to establish whether up-regulation could effectively enhance arousal levels during sexual stimuli, and whether such a training would simultaneously reduce disgust. Students (N = 163, mean age = 20.73 years, SD = 2.35) were trained in up-regulation of affect using either a sexual arousal film (i.e., female-friendly erotic movie) or a threat arousal film clip (i.e., horror movie), while control groups viewed the films without training instructions. Following this, participants viewed and rated state emotions during a series of pictures (sexual, disgusting, or neutral). Up-regulation of mood successfully enhanced general arousal in both groups, yet these arousal levels were not paralleled by reductions in disgust. Overall, the findings indicate that emotion regulation training by maximizing positive affect and general arousal could be an effective instrument to facilitate affect-related disturbances in sexual dysfunctions.

    Previous research suggests that sexual stimuli increase testosterone (T) in women and shows inconsistent effects of sexual arousal on cortisol (C), but effects of cognitive aspects of arousal, rather than behaviors or sensory stimuli, are unclear. The present study examined whether sexual thoughts affect T or C and whether hormonal contraceptive (HC) use moderated this effect, given mixed findings of HC use confounding hormone responses. Participants (79 women) provided a baseline saliva sample for radioimmunoassay. We created the Imagined Social Situation Exercise (ISSE) to test effects of imagining social interactions on hormones, and participants were assigned to the experimental (sexual) or one of three control (positive, neutral, stressful) conditions. Participants provided a second saliva sample 15 min post-activity. Results indicated that for women not using HCs, the sexual condition increased T compared to the stressful or positive conditions. In contrast, HC using women in the sexual condition had decreased T relative to the stressful condition and similar T to the positive condition. The effect was specific to T, as sexual thoughts did not change C. For participants in the sexual condition, higher baseline T predicted larger increases in sexual arousal but smaller increases in T, likely due to ceiling effects on T. Our results suggest that sexual thoughts change T but not C, baseline T levels and HC use may contribute to variation in the T response to sexual thoughts, and cognitive aspects of sexual arousal affect physiology.

    This study was conducted to test interpersonal, attitudinal, and sexual predictors of sexual assertiveness in a Spanish sample of 1,619 men and 1,755 women aged 18-87 years. Participants completed measures of sexual assertiveness, solitary and dyadic sexual desire, sexual arousal, erectile function, sexual attitudes, and frequency of partner abuse. In men, higher sexual assertiveness was predicted by less non-physical abuse, more positive attitudes toward sexual fantasies and erotophilia, higher dyadic desire, and higher sexual arousal. In women, higher sexual assertiveness was predicted by less non-physical abuse, less solitary sexual desire and higher dyadic sexual desire, arousal, erotophilia, and positive attitudes towards sexual fantasies. Results were discussed in the light of prevention and educational programs that include training in sexual assertiveness skills. PMID:22875718

    Sexual offenses cause significant harm to victims, their families, and society as a whole and thus are an important social concern. While it is commonly assumed that sexual offenses are committed solely by males, research has shown that approximately 5 % of sex crimes in the USA and Canada are committed by females. Penile plethysmography (PPG) is a method to measure male genital arousal, which is commonly used in the assessment and treatment of male sex offenders and men with paraphilic sexual interests. Similarly, vaginal photoplethysmography (VPP) is a test to measure female genital arousal and is commonly used to assess female sexual dysfunctions. Although VPP is currently the most validated method to measure genital arousal in women, its use with female sex offenders or females with paraphilic sexual interests has been almost nonexistent. One explanation for this is that some research has suggested that female genital arousal may not be category-specific, meaning that women will respond to any sexual cues, not just those involving their preferred sexual interests. However, not all research supports this finding. Due to the potential benefits of using VPP in the assessment and treatment of female sex offenders or females with paraphilic sexual interests, it is important that further research be done before dismissing the use of VPP in forensic populations. The purpose of this article is to review the current research on VPP and its applicability to female sex offenders and females with paraphilic sexual interests. PMID:25749745

Results Many unique physiologic methods of evaluating female sexual function have been developed over the last four decades. Each method has its benefits and limitations. Conclusions Many physiologic methods exist, but most are not well-validated. Additionally, there has been an inability to correlate most physiologic measures with subjective measures of sexual arousal. Furthermore, given the complex nature of the sexual response in women, physiologic measures should be considered in context of other data, including the history, physical exam, and validated questionnaires. Nonetheless, the existence of appropriate physiologic measures is vital to our understanding of female sexual function and dysfunction. PMID:19046582

    Introduction.? Women with provoked vestibulodynia (PVD) report lower sexual arousal than nonaffected women, however, laboratory studies of arousal have reported contradictory results about whether group differences exist in genital and subjective arousal. Aim.? To examine genital and subjective sexual arousal in women with and without PVD. Methods.? Eligible women with and without PVD (N?=?42) attended a laboratory session that included an interview, questionnaire completion, and genital imaging. A direct measure of superficial blood flow-laser Doppler imaging-was used to assess vulvar blood flow levels while participants watched three films, including an erotic film. Participants answered questions about their level of sexual arousal before, during, and after the erotic film. Main Outcome Measures.? Average vulvar blood flow levels during the baseline and erotic films, numerical ratings of subjective sexual arousal and anxiety, as well as questionnaire measures of arousal. Results.? There was a significant group difference in genital arousal, whereby the PVD group showed a lower genital response to the erotic film, as well as a significant interaction between baseline blood flow and group membership. Separate group regression analyses demonstrated that baseline blood flow explained a substantial amount of the variance in erotic film blood flow in the control group (70%), while only 27% was explained by this variable in the PVD group. There were no differences in subjective sexual arousal or anxiety between the groups. Across questionnaire measures, women with PVD reported lower sexual arousal than the control group. Conclusions.? The results suggest that women with PVD show lower genital responsiveness than nonaffected women to sexual stimuli in a laboratory setting and that their genital arousal is likely impacted by a number of biopsychosocial factors.

The present research sought to test (1) whether sexual arousal effects could be replicated under more controlled laboratory settings, (2) whether women showed the same pattern of results, and (3) whether this effect was specific to sexual disinhibition or would generalize to non-sexual disinhibited behavior. In two experimental studies, male and female participants (Study 1: N = 84; Study 2: N = 86) were either sexually aroused by acoustically presented erotic narratives or listened to sexually non-arousing neutral narratives. Afterwards, they self-estimated their likelihood of engaging in a variety of behaviors that could be characterized as sexual or non-sexual disinhibited behavior. Results replicated the previously established effect of sexual disinhibition under sexual arousal for men and provided the first evidence for a similar effect in women. No arousal effects were observed for non-sexual behavior, rendering alternative explanations based on mere indifferent responding unlikely. The discussion focused on a plausible explanation for this effect. PMID:25091213

    The purpose of this study was to determine if self-identified bisexual, heterosexual, and homosexual men show differential genital and subjective arousal patterns to video presentations of bisexual, heterosexual, male homosexual, and lesbian sexual interactions. It was predicted that, relative to heterosexual and homosexual stimuli, bisexual men would show the highest levels of sexual arousal to bisexual erotic material, while this stimulus would induce relatively low levels of response in heterosexual and homosexual men. A sample of 59 men (19 homosexual, 13 bisexual, and 27 heterosexual) were presented with a series of 4-min sexual videos while their genital and subjective sexual responses were measured continuously. Bisexual men did not differ significantly in their responses to male homosexual stimuli (depicting men engaging in sex) from homosexual men, and they did not differ significantly in their responses to heterosexual (depicting two women, without same-sex contact, engaged in sex with a man) and lesbian (depicting women engaging in sex) stimuli from heterosexual men. However, bisexual men displayed significantly higher levels of both genital and subjective sexual arousal to a bisexual stimulus (depicting a man engaged in sex with both a man and a woman) than either homosexual or heterosexual men. The findings of this study indicate that bisexuality in men is associated with a unique and specific pattern of sexual arousal. PMID:21387117

    Background Theories of personality have posited an increased arousal response to external stimulation in impulsive individuals. However, there is a dearth of studies addressing the neural basis of this association. Methods We recorded skin conductance in 26 individuals who were assessed with Barratt Impulsivity Scale (BIS-11) and performed a stop signal task during functional magnetic resonance imaging. Imaging data were processed and modeled with Statistical Parametric Mapping. We used linear regressions to examine correlations between impulsivity and skin conductance response (SCR) to salient events, identify the neural substrates of arousal regulation, and examine the relationship between the regulatory mechanism and impulsivity. Results Across subjects, higher impulsivity is associated with greater SCR to stop trials. Activity of the ventromedial prefrontal cortex (vmPFC) negatively correlated to and Granger caused skin conductance time course. Furthermore, higher impulsivity is associated with a lesser strength of Granger causality of vmPFC activity on skin conductance, consistent with diminished control of physiological arousal to external stimulation. When men (n = 14) and women (n = 12) were examined separately, however, there was evidence suggesting association between impulsivity and vmPFC regulation of arousal only in women. Conclusions Together, these findings confirmed the link between Barratt impulsivity and heightened arousal to salient stimuli in both genders and suggested the neural bases of altered regulation of arousal in impulsive women. More research is needed to explore the neural processes of arousal regulation in impulsive individuals and in clinical conditions that implicate poor impulse control. PMID:26079873

    Sexual coercion is a significant problem on college campuses despite numerous attempts to better understand and prevent it. Some criminological research has examined the role of sexual arousal in decisions to use coercion and force, while psychologists have studied how overperception of sexual interest relates to coercive behaviors. The current study combines these two lines of research to examine whether sexual arousal increases the perception of sexual interest in a hypothetical coercion scenario. A sample of 387 college males were randomly placed into arousal and control conditions and asked to watch either erotic material or a lecture and complete questions regarding a common social dating scenario. Bivariate and multivariate results indicated significant relationships between sexual arousal and overperception of sexual intent with the decision to engage in sexually coercive behaviors, as well as a mediation effect. The implications for theory and sexual assault prevention are discussed. PMID:24407143

    Sexual concordance refers to the degree to which two aspects of human sexual arousal (genital response and self-reported sexual arousal) correspond with each other. Researchers have consistently reported a sex difference in sexual concordance: The relationship between genital responses and reported feelings of sexual arousal in men is positive and large, whereas the relationship in women is positive but much smaller than that seen in men. The study of interoception--people's awareness of their physiological states--reveals a similar sex difference: Men are more aware of a variety of (non-genital) responses (e.g., heart rate) than women in the laboratory. The purpose of the current study was to investigate whether the sex difference in sexual concordance was related to a broader sex difference in interoception. Twenty men and 20 women were presented with twelve 90 s sexual and non-sexual film clips while their genital responses, heart rate, and respiration rate were measured. Participants also estimated their physiological responses. As expected, men were significantly more sexually concordant than women. Men were also significantly more aware of their heart rate, but there was no significant sex difference in respiration rate awareness. Sexual concordance was not significantly correlated with either heart rate or respiration rate awareness. The results suggest that the sex difference in sexual concordance may be a unique phenomenon, separate from general awareness of physiological states. PMID:22399053

    Prior studies consistently report that men's genital responses correspond to their sexual activity interests (consenting vs. coercive sex) whereas women's responses do not. For women, however, these results may be confounded by the sexual activities studied and lack of suitable controls. We examined the subjective and genital arousal responses of men and women with conventional (22 men and 15 women) or masochistic sexual interests (16 men and 17 women) to narratives describing conventional sex or masochistic sex. The aims of the studies were twofold: (1) to examine whether gender differences in the specificity of sexual arousal previously observed for gender also exist for sexual activity interests; and (2) to examine whether men and women with masochistic sexual interests demonstrate specificity of sexual response for their preferred sexual activities. Surprisingly, the pattern of results was very similar for men and women. Both men and women with conventional sexual interests (WCI) reported more sexual arousal, and responded more genitally, to conventional than to masochistic sex, demonstrating specificity of sexual arousal for their preferred sexual activities. Despite showing specificity for conventional sexual activities, the genital responses of WCI were still gender nonspecific. In contrast, women and men with masochistic sexual interests demonstrated nonspecific subjective and genital responses to conventional and masochistic sex. Indices of genital and subjective sexual arousal to masochistic versus conventional stimuli were positively and significantly correlated with self-reported thoughts, fantasies, interests, and behaviors involving masochism. The results suggest that gender similarities in the specificity of sexual arousal for sexual activity exist despite consistent gender differences in the specificity of sexual arousal for gender.

    Arousal-oriented online sexual activities (OSAs) are any activities on the Internet that involve sexually explicit and/or sexually arousing stimuli. These can be solitary-arousal activities, requiring only one person be involved. They can also be partnered-arousal activities that involve at least two people interacting (Shaughnessy, Byers, & Walsh, 2011). Most researchers have focused on the negative outcomes of arousal-oriented OSAs on users' sexual life and life in general. Yet, these activities can also have positive outcomes. In two separate studies, we examined men's and women's perceptions of the positive and negative outcomes of their solitary- and partnered-arousal OSA experience. Study 1 included heterosexual university students (N = 191); Study 2 consisted of heterosexual and sexual minority individuals from the community (N = 316). Participants completed a background questionnaire and measures of their solitary- and partnered-arousal OSA experience and outcomes of these experiences. Overall, solitary- and partnered-arousal OSA was common among study participants. In both studies, participants reported significantly greater positive than negative outcomes of their solitary- and partnered-arousal OSAs, albeit the overall impact was small. We did not find significant gender differences or differences by sexual orientation in positive or negative outcomes of arousal-oriented OSAs. Our results suggest that, for most people, participating in solitary- and partnered-arousal OSAs has little impact on them. PMID:23740466

    The relationship between automatic thoughts and emotions presented during sexual activity and their correlation with sexual arousal was investigated. A total of 491 individuals (163 women and 232 men without sexual problems and 47 women and 49 men with a DSM-IV diagnosis of sexual dysfunction) completed the Sexual Modes Questionnaire (SMQ; Nobre and Pinto-Gouveia, Journal of Sex Research, 40, 368-382, 2003). Results indicated several significant correlations among automatic thoughts, emotions, and sexual arousal. Erection concern thoughts in the men and failure/disengagement thoughts and lack of erotic thoughts in the women presented the most significant negative correlations with sexual arousal. Additionally, sadness and disillusion were positively related to these negative cognitions and negatively associated with sexual arousal in both sexes. On the other hand, pleasure and satisfaction were negatively associated with the above-mentioned negative cognitions and positively associated with subjective sexual arousal in both men and women. Overall, findings support the hypothesis that cognitive, emotional, and behavioral dimensions are closely linked and suggest a mode typical of sexual dysfunction composed of negative automatic thoughts, depressive affect, and low subjective sexual arousal.

    Previous studies have indicated that women with diabetes mellitus are at higher risk to develop sexual dysfunctions. In the current study, we hypothesized that lower genital arousal response-as a consequence of diabetes-related damage to nerves and blood vessels-might play a part in these higher prevalence rates. Vaginal blood flow, subjective sexual response, and clitoral sensitivity were compared between women with diabetes and healthy controls, and associations with diabetes complications were investigated. In pre- and postmenopausal women with type 1 diabetes (n = 42) and healthy controls (n = 46), vaginal blood flow was measured as vaginal pulse amplitude (VPA). VPA was assessed at rest, during erotic film viewing, and during vibrotactile clitoral stimulation. Subjective sexual arousal was measured using a questionnaire. Clitoral sensitivity was assessed by a vibration perception test. Data on diabetes complications were obtained from medical records, and neuropathy was assessed by quantitative sensory testing. VPA, subjective sexual arousal, and clitoral sensitivity were not significantly different between women with diabetes and controls. Nevertheless, women with diabetes who had retinopathy showed significantly lower VPA than women without retinopathy, and women with diabetes who had neuropathy showed significantly higher sensation thresholds for vibrotactile clitoral stimulation. The results do not support the hypothesis of a disrupted genital arousal response in women with diabetes. However, the observed associations between retinopathy and vaginal blood flow, and between neuropathy and clitoral sensitivity, suggest that diabetes-related complications might adversely affect the physiological basis of female sexual response.

    Background Sex and disgust are basic, evolutionary relevant functions that are often construed as paradoxical. In general the stimuli involved in sexual encounters are, at least out of context strongly perceived to hold high disgust qualities. Saliva, sweat, semen and body odours are among the strongest disgust elicitors. This results in the intriguing question of how people succeed in having pleasurable sex at all. One possible explanation could be that sexual engagement temporarily reduces the disgust eliciting properties of particular stimuli or that sexual engagement might weaken the hesitation to actually approach these stimuli. Methodology Participants were healthy women (n?=?90) randomly allocated to one of three groups: the sexual arousal, the non-sexual positive arousal, or the neutral control group. Film clips were used to elicit the relevant mood state. Participants engaged in 16 behavioural tasks, involving sex related (e.g., lubricate the vibrator) and non-sex related (e.g., take a sip of juice with a large insect in the cup) stimuli, to measure the impact of sexual arousal on feelings of disgust and actual avoidance behaviour. Principal Findings The sexual arousal group rated the sex related stimuli as less disgusting compared to the other groups. A similar tendency was evident for the non-sex disgusting stimuli. For both the sex and non-sex related behavioural tasks the sexual arousal group showed less avoidance behaviour (i.e., they conducted the highest percentage of tasks compared to the other groups). Significance This study has investigated how sexual arousal interplays with disgust and disgust eliciting properties in women, and has demonstrated that this relationship goes beyond subjective report by affecting the actual approach to disgusting stimuli. Hence, this could explain how we still manage to engage in pleasurable sexual activity. Moreover, these findings suggest that low sexual arousal might be a key feature in the maintenance of particular sexual dysfunctions. PMID:22984465

    Women with a history of childhood sexual abuse (CSA) experience dissociative symptoms and sexual difficulties with greater frequency than women without a history of CSA. Current models of sexual dysfunction for sexual abuse survivors suggest that dissociation may mediate the relationship between CSA and sexual arousal difficulties. Dissociation, however, is often conceptualized as a single construct in studies of CSA and not as separate domains as in the dissociation literature. In the present study, women with (CSA, N = 37) and without (NSA, N = 22) a history of CSA recruited from the community were asked to indicate the frequency and intensity of their experience in two dissociation subgroups, derealization and depersonalization, during sex with a partner and in their daily life. Findings showed that, in the NSA group, more depersonalization during sex with a partner was associated with lower sexual arousal functioning. However, for both the NSA and CSA groups, more derealization during sex was associated with higher sexual arousal functioning. No measure of dissociation was significantly associated with sexual responses in the laboratory. These findings highlight the importance of distinguishing between different forms of dissociation (i.e., derealization and depersonalization) in the study of sexual arousal functioning. In addition, the findings challenge the notion that dissociation is a main predictor of sexual arousal problems in survivors of CSA and suggest that a more nuanced relationship may exist.

    Sexual arousal is a motivational state that moves humans toward situations that inherently pose a risk of disease transmission. Disgust is an emotion that adaptively moves humans away from such situations. Incongruent is the fact that sexual activity is elementary to human fitness yet involves strong disgust elicitors. Using an experimental paradigm, we investigated how these two states interact. Women (final N=76) were assigned to one of four conditions: rate disgust stimuli then watch a pornographic clip; watch a pornographic clip then rate disgust stimuli; rate fear stimuli then watch a pornographic clip; or watch a pornographic clip then rate fear stimuli. Women’s genital sexual arousal was measured with vaginal photoplethysmography and their disgust and fear reactions were measured via self-report. We did not find that baseline disgust propensity predicted sexual arousal in women who were exposed to neutral stimuli before erotic content. In the Erotic-before-Disgust condition we did not find that sexual arousal straightforwardly predicted decreased image disgust ratings. However, we did find some evidence that sexual arousal increased self-reported disgust in women with high trait disgust and sexual arousal decreased self-reported disgust in women with low trait disgust. Women who were exposed to disgusting images before erotic content showed significantly less sexual arousal than women in the control condition or women exposed to fear-inducing images before erotic content. In the Disgust-before-Erotic condition the degree of self-reported disgust was negatively correlated with genital sexual arousal. Hence, in the conflict between the ultimate goals of reproduction and disease avoidance, cues of the presence of pathogens significantly reduce the motivation to engage in mating behaviors that, by their nature, entail a risk of pathogen transmission.

    Time perception, crucial for adaptive behavior, has been shown to be altered by emotion. An arousal-dependent mechanism is proposed to account for such an effect. Yet, physiological measure of arousal related with emotional timing is still lacking. We addressed this question using skin conductance response (SCR) in an emotion regulation paradigm.…

    Observational stance refers to the perspective a person takes while viewing a sexual stimulus, either as a passive observer (observer stance) or an active participant (participant stance). The objective of the current study was to examine the relationship between observational stance and sexual arousal (subjective and genital) across a range of sexual stimuli that do or do not correspond with a participant's sexual attraction (preferred or nonpreferred stimuli, respectively). Regression analyses revealed that, for men (n = 44), participant stance significantly predicted subjective and genital arousal. Women's (n = 47) observer and participant stance predicted subjective arousal but not genital arousal. Analysis of variance showed that participant stance was greatest under preferred sexual stimuli conditions for all groups of participants, while observer stance scores revealed a less consistent pattern of response. This was particularly true for opposite-sex-attracted women, whose ratings of observer stance were lowest for preferred stimuli. Observational stance does not appear to account for gender differences in specificity of sexual arousal; for men, however, participant stance uniquely predicted genital response after controlling for sexual attractions. Similarities in the relationships between men's and women's observational stance and sexual responses challenge previous claims of gender differences in how men and women view erotica. PMID:23514448

    The assessment of sexual arousal in men and women informs theoretical studies of human sexuality and provides a method to assess and evaluate the treatment of sexual dysfunctions and paraphilias. Understanding measures of arousal is, therefore, paramount to further theoretical and practical advances in the study of human sexuality. In this meta-analysis, we review research to quantify the extent of agreement between self-reported and genital measures of sexual arousal, to determine if there is a gender difference in this agreement, and to identify theoretical and methodological moderators of subjective-genital agreement. We identified 132 peer- or academically-reviewed laboratory studies published between 1969 and 2007 reporting a correlation between self-reported and genital measures of sexual arousal, with total sample sizes of 2,505 women and 1,918 men. There was a statistically significant gender difference in the agreement between self-reported and genital measures, with men (r = .66) showing a greater degree of agreement than women (r = .26). Two methodological moderators of the gender difference in subjective-genital agreement were identified: stimulus variability and timing of the assessment of self-reported sexual arousal. The results have implications for assessment of sexual arousal, the nature of gender differences in sexual arousal, and models of sexual response. PMID:20049519

    Neonatal studies suggest elevated arousal can negatively influence perceptual and cognitive processes during early development. The authors explored this issue during the prenatal period by pharmacologically elevating physiological arousal in bobwhite quail (Colinus virginianus) embryos during exposure to a maternal call, then assessing preference for the familiar call following hatching. Embryos receiving norepinephrine showed a prenatal elevation in heart rate and failed to demonstrate a preference for the familiar call following hatching. Embryos not receiving norepinephrine showed no elevation in heart rate and demonstrated a preference for the familiar call. These results indicate elevated arousal can interfere with perceptual learning during the prenatal period and provide additional evidence for an optimal window of arousal necessary to foster species-typical perceptual functioning during early development.

    This study examined the effects of reappraising stress arousal on affective displays, physiological responses, and social performance during an evaluative situation. Participants were sampled from across the social anxiety spectrum and instructed to reappraise arousal as beneficial or received no instructions. Independent raters coded affective displays, nonverbal signaling, and speech performance. Saliva samples collected at baseline and after evaluation were assayed for salivary alpha-amylase (sAA), a protein that indexes sympathetic activation. Arousal reappraisal participants exhibited less shame and anxiety, less avoidant nonverbal signaling, and performed marginally better than no instruction controls. Reappraisal participants also exhibited increased levels of sAA and increased appraisals of coping resources compared with controls. Furthermore, stress appraisals mediated relationships between reappraisal and affective displays. This research indicates that reframing stress arousal can improve behavioral displays of affect during evaluative situations via altering cognitive appraisals. PMID:24749642

    Little is known about arousal to socially stressful situations in children with Autism Spectrum Disorders. This preliminary study investigates physiologic arousal in children with high functioning autism (HFA, n=19) compared to a comparison group (n=11) before, during, and after the Trier Social Stress Test. The HFA group was more likely to have a decrease in salivary cortisol following the stressor, while the comparison group was more likely to have an increase (p=.02). However, there was no difference in electrodermal activity, a measure of sympathetic arousal, or vagal tone, a measure of parasympathetic activity, between groups. These findings implicate a differential neuroendocrine response to social stress in children with HFA despite similar sympathetic and parasympathetic responses during a stressor. Further studies are required to substantiate this finding. PMID:22081773

    Human studies suggest that prior emotional responses are stored within the brain as associations called somatic markers and are recalled to inform rapid decision-making. Consequently, behavioural and physiological indicators of arousal are detectable in humans when making decisions, and influence decision outcomes. Here we provide the first evidence of anticipatory arousal around the time of decision-making in non-human animals. Chickens were subjected to five experimental conditions, which varied in the number (one versus two), type (mealworms or empty bowl) and choice (same or different) of T-maze goals. As indicators of arousal, heart-rate and head movements were measured when goals were visible but not accessible; latency to reach the goal indicated motivation. We found a greater increase in heart-rate from baseline to the goal-viewing period, more head movements and shorter latencies in all conditions including mealworms compared to those with empty bowls. More head movements when two mealworm bowls were available compared to just one, and prior to occasions when hens accessed an empty bowl rather than declining to move, showed that arousal preceded and influenced decision-making. Our results provide an important foundation for investigating arousal during animal decision-making and suggest that the somatic-marker hypothesis might not only apply to humans. PMID:24513559

    Using a randomly selected community sample of 200 Danish young adult men and women in a randomized experimental design, the study investigated the effects of a personality trait (agreeableness), past pornography consumption, and experimental exposure to non-violent pornography on attitudes supporting violence against women (ASV). We found that lower levels of agreeableness and higher levels of past pornography consumption significantly predicted ASV. In addition, experimental exposure to pornography increased ASV but only among men low in agreeableness. This relationship was found to be significantly mediated by sexual arousal with sexual arousal referring to the subjective assessment of feeling sexually excited, ready for sexual activities, and/or bodily sensations associated with being sexually aroused. In underscoring the importance of individual differences, the results supported the hierarchical confluence model of sexual aggression and the media literature on affective engagement and priming effects.

    The associations between attachment representations of adopted young adults and their experiential and physiological arousal to infant crying were examined. Attachment representations were assessed with the Attachment Script Assessment (ASA), and the young adults listened to infant cries, during which ratings of cry perception were collected and physiological reactivity was measured. Secure adoptees showed a well-integrated response to infant distress: heart-rate increases and respiratory sinus arrhythmia (RSA) withdrawal were coupled with heightened perception of urgency in these individuals. In insecure adoptees RSA withdrawal was absent, and a combination of lowered perceived urgency and heightened sympathetic arousal was found, reflecting a deactivating style of emotional reactivity. Overall, our findings support the idea that internal working models of attachment explain individual differences in the way attachment-related information is processed. PMID:25460537

    We conducted a literature review of patients' conditions described under persistent genital arousal disorder and restless genital syndrome, vulvodynia and male genital skin pain of unknown aetiology (penoscrotodynia). Our aim is to improve the understanding of the condition, unify nomenclature and promote evidence-based practice. The most prominent symptom in persistent genital arousal disorder and restless genital syndrome is a spontaneous, unwelcomed, intrusive and distressing vulval sensation. There are similarities between the clinical presentation of vulvodynia, penoscrotodynia, persistent genital arousal disorder and restless genital syndrome patients. The aetiology of persistent genital arousal disorder and restless genital syndrome, similar to vulvodynia, could be better explained in terms of neuro-vascular dysfunction, genital peripheral neuropathy and/or dysfunctional micro-vascular arterio-venous shunting. Erythromelalgia lends itself to explain some cases of restless genital syndrome, who have concurrent restless legs syndrome; and therefore draw parallels with the red scrotum syndrome. The published literature supports the concept of classifying restless genital syndrome as a sub-type of vulvodynia rather than sexual dysfunction. PMID:23970620

    Wheeler and Rubin (1987) advanced evidence that penile volume responses (PVRs) were no more sensitive than penile circumference responses (PCRs) in measuring erection which the authors incorrectly identified with sexual arousal. Knowledge of the literature would have led them to question that identification and the methodology of their study. PVRs have repeatedly been demonstrated to assess validly not erection but the sexual orientation of individuals, when derived from the early stage of erectile response to brief stimuli that were from their onset of moderate erotic strength. PCR assessment has been of the degree of erection to stimuli of 2-10 min duration. No success has been reported using PCR measures of erection to classify subjects individually as to their sexual orientation. Classification of groups of 30 but not 6 homosexuals was successful using their PCRs to nudes. Attempts to identify rapists and pedophiles from normals, and aggressive from nonaggressive rapists and pedophiles by PCRs have failed to be replicated. In comparing PVRs and PCRs, Wheeler and Rubin used as stimuli three 10-min presentations of a film which apparently did not immediately introduce erotic material. This procedure would not elicit meaningful PVRs. Though never validated as a measure of individuals' sexual arousal, PCR measures of erection are currently widely recommended for assessment and determining treatment of individual sex offenders. If these assessments could affect or are believed by the offenders to affect the outcome of the legal processes in which they are involved, the procedure is not only scientifically unsupported, it is unethical.

    The physiology of small mammalian hibernators shifts profoundly over a year, from summer homeothermy to winter heterothermy. Torpor-arousal cycles define high-amplitude tissue activity fluctuations in winter, particularly for skeletal muscle, which contributes to the energetically demanding rewarming process via shivering. To better understand the biochemistry underlying summer-winter and torpor-arousal transitions, we applied two-dimensional gel electrophoresis coupled with liquid chromatography/mass spectrometry/mas spectrometry to the soluble proteins from hindlimb muscle of 13-lined ground squirrels (Ictidomys tridecemlineatus) in two summer and six winter states. Two hundred sixteen protein spots differed by sampled state. Significantly, intrawinter protein adjustment was a minor component of the dataset despite large discrepancies in muscle activity level among winter states; rather, the bulk of differences (127/138 unequivocally identified proteins spots) occurred between summer and winter. We did not detect any proteomic signatures of skeletal muscle atrophy in this hibernator nor any differential seasonal regulation of protein metabolism. Instead, adjustments to metabolic substrate preferences dominated the detected proteomic differences. Pathways of carbohydrate metabolism (glycolysis and gluconeogenesis) were summer enriched, whereas the winter proteome was enriched for fatty acid ?-oxidation. Nevertheless, our data suggest that some reliance on carbohydrate reserves is maintained during winter. Phosphoglucomutase (PGM1), which reversibly prepares glucose subunits for either glycolysis or glycogenesis, showed apparent winter state-specific phosphorylation. PGM1 was phosphorylated during rewarming and dephosphorylated by interbout arousal, implying that glucose supplements lipid fuels during rewarming. This, along with winter elevation of TCA cycle enzymes, suggests that hindlimb muscles are primed for rapid energy production and that carbohydrates are an important fuel for shivering thermogenesis.

    Although studies suggest that alcohol increases women’s sexual desire, no studies to our knowledge have examined the effects of acute alcohol intoxication on women’s sexual desire. The majority of research examining alcohol’s effects on sexual arousal in women suggests that alcohol increases self-reported arousal. In an alcohol administration study in which women projected themselves into an eroticized scenario depicting a consensual sexual encounter with a new male partner, we examined the effects of alcohol and condom condition on women’s sexual desire and arousal. The moderating effects of sex-related alcohol expectancies were also examined. Results revealed that alcohol intoxication was related to less desire to engage in sex with a new partner and condom presence was related to more desire. Alcohol interacted with sexual disinhibition alcohol expectancies, indicating that more expectancy endorsement was associated with greater sexual desire and self-reported arousal in the alcohol condition, but not the control condition. Condom condition had no effect on self-reported sexual arousal. The present research suggests that sexual desire merits research attention in non-clinical samples, and experimental methodology can provide valuable information about alcohol’s influence on women’s sexual desire, thus advancing our understanding of this relationship beyond cross-sectional correlations. The current findings also provide evidence that sex-related alcohol expectancies may play an important role in alcohol-involved sexual experiences including desire and arousal. PMID:23661324

    Vespertilionid bats are thought to have a dissociated pattern of reproduction; mating occurs in autumn as well as during periodic arousals from hibernation when testes are regressed and ovaries are “in stasis.” Sex steroid levels in both sexes are basal at this time. This pattern would indicate that sex steroids per se may not be activating sexual behavior. Gonadectomy of

    The frequency of spontaneous genital arousal (GA) and persistent genital arousal disorder (PGAD) in women is unknown. The aim of this study was to conduct an anonymous survey to assess the frequency and nature of spontaneous GA and PGAD in women attending a walk-in sexual health clinic in London. Female patients completed a questionnaire, which included demographic information, medical, psychiatric and gynaecology history, the hospital anxiety and depression scale, and a somatization scale. Patients were then asked to complete three questions regarding spontaneous and persistent GA. Any patient with one or more symptoms then answered questions about the distress, intensity and duration of sensations. Ninety-six subjects participated. The mean age was 28.97 years. Thirty-two women (33.3%) answered 'yes' to at least one question regarding spontaneous or persistent GA and six women (6.3%) women answered 'yes' to all three questions. Only one subject fulfilled all five diagnostic criteria for PGAD. In conclusion, women report a high rate of spontaneous GA in the absence of desire or excitement. This has not been well described previously. A small proportion of women report multiple features of spontaneous and persistent GA, with chronicity over years, but without distress in most cases. Larger studies are needed. PMID:19625580

    In three experiments, we explore the link between peripheral physiological arousal and logicality in a deductive reasoning task. Previous research has shown that participants are less likely to provide normatively correct responses when reasoning about emotional compared to neutral contents. Which component of emotion is primarily involved in this effect has not yet been explored. We manipulated the emotional value of the reasoning stimuli through classical conditioning (Experiment 1), with simultaneous presentation of negative/neutral pictures (Experiment 2), or by using intrinsically negative/neutral words (Experiment 3). We measured skin conductance (SC) and subjective affective ratings of the stimuli. In all experiments, we observed a negative relationship between SC and logicality. Participants who showed greater SC reactivity to negative stimuli compared to neutral stimuli were more likely to make logical errors on negative, compared to neutral reasoning contents. There was no such link between affective ratings of the stimuli and the effect of emotion on reasoning. PMID:21106478

    Previous research has shown that playing violent video game exposure can increase aggressive thoughts, aggressive feelings, and physiological arousal. This study compared the effects that playing a realistic violent, unrealistic violent, or nonviolent video game for 45 min has on such variables. For the purpose of this study, realism was defined as the probability of seeing an event in real life. Participants (N=74; 39 male, 35 female) played either a realistic violent, unrealistic violent, or nonviolent video game for 45 min. Aggressive thoughts and aggressive feelings were measured four times (every 15 min), whereas arousal was measured continuously. The results showed that, though playing any violent game stimulated aggressive thoughts, playing a more realistic violent game stimulated significantly more aggressive feelings and arousal over the course of play.

    Most men have a category-specific pattern of genital and subjective sexual arousal, responding much more strongly to erotic stimuli depicting their preferred sex than to erotic stimuli depicting their nonpreferred sex. In contrast, women tend to have a less specific arousal pattern. To better understand this sex difference, we used neuroimaging to explore its neural correlates. Heterosexual and homosexual women viewed erotic photographs of either men or women. Evoked neural activity was monitored via fMRI and compared with responses to the same stimuli in heterosexual and homosexual men. Overall, a network of limbic (as well as the anterior cingulate) and visual processing regions showed significantly less category-specific activity in women than men. This was primarily driven by weaker overall activations to preferred-sex stimuli in women, though there was also some evidence of stronger limbic activations to nonpreferred-sex stimuli in women. Primary results were similar for heterosexual and homosexual participants. Women did show some evidence of category-specific responses in the visual processing regions, although even in these regions they exhibited less differential activity than men. In the anterior cingulate, a region with high concentrations of sex-hormone receptors, subjective and neural category specificity measures correlated positively for women but negatively for men, suggesting a possible sex difference in the role of the anterior cingulate. Overall, results suggest that men tend to show more differentiated neural responses than do women to erotic photographs of one sex compared to the other sex, though women may not be entirely indifferent to which sex is depicted.

    Previous studies have established that neutral olfactory cues associated with sexual reward or inhibition become conditioned stimuli that direct male or female rats toward or away from potential sex partners bearing the cue. Here we examined the ability of a somatosensory cue to exert stimulus control over sexual arousal and copulation in male rats. In the first experiment, two groups of sexually naïve male rats had their first copulatory experiences with receptive females in bilevel chambers with or without a rodent jacket. On a final copulatory test, half of the rats in each group were tested with the jacket on or off. Rats trained and tested without the jacket copulated normally, as did rats trained and tested with the jacket on, and rats trained without the jacket but tested with the jacket on. However, significantly fewer rats trained with the jacket on but tested with the jacket off copulated to ejaculation, and those that did made significantly fewer anticipatory level changes and had fewer significantly longer mount, intromission, and ejaculatory latencies, and fewer ejaculations. In the second experiment, one group of sexually naïve males was given differential conditioning trials in bilevel chambers to associate the jacket on with sexual reward (copulation to ejaculation with a sexually receptive female) and the jacket off with sexual inhibition (thwarted copulatory attempts with a sexually nonreceptive female). A second group had the opposite order of association. A final test with receptive females was made for all males with the jacket on. Males trained to associate the jacket with excitation displayed normal copulation whereas males trained to associate the jacket with inhibition displayed significantly fewer anticipatory level changes and ejaculations, and had significantly longer ejaculation latencies. Thus, somatosensory cues can signal sexual excitation or inhibition in male rats depending on the conditioning history. PMID:23954746

    This study compared the brain activation patterns associated with visual sexual arousal in connection with sexual hormone levels in postoperative male-to-female (MTF) transsexuals and normal premenopausal and menopausal women using 3.0 T functional MRI. A total of 30 volunteers including 10 premenopausal women, 10 menopausal women, and 10 postoperative MTF transsexuals who had undergone sex reassignment surgery participated in this study. Brain activity was measured while viewing erotic male and female nude pictures. The free testosterone and estradiol levels of the postoperative MTF transsexuals were not in the normal range seen in normal premenopausal women, but were in range seen in menopausal women. The postoperative MTF transsexuals showed significantly higher activities in the hippocampus, parahippocampal gyrus, amygdala, putamen, globus pallidus, thalamus, and head of caudate nucleus in response to erotic male nude pictures in contrast to female pictures (P<0.005). The predominant activation areas observed in the postoperative MTF transsexuals in contrast to the menopausal women when viewing male nude pictures included the insula, hippocampus, thalamus, and putamen (P<0.005). Similar to the postoperative MTF transsexuals, the premenopausal women showed significantly higher activities than menopausal women in the insula, hippocampus, thalamus, and parahippocampal gyrus (P<0.005). This study revealed that the brain activation patterns associated with visual sexual arousal in postoperative MTF transsexuals are similar to those in premenopausal women, although the sexual hormone levels in the postoperative MTF transsexuals are in the average range of those in menopausal women.

    The neurobiological bases of human sexual behavior are only partly understood. The etiology of most human sexual dysfunctions is not understood at all. Nevertheless, substantial progress has been made in the treatment of some male sexual disorders. The prime example should be erectile deficiency, where several efficient and safe treatments are available. Pharmacological treatment for premature ejaculation is also available, although it is still in an early stage. Disorders of sexual desire have attracted much attention when women are affected but far less so when men are concerned. Whereas animal models appropriate for testing treatments for problems with erection and premature ejaculation are available, it is questionable whether such models of the desire disorders have predictive validity. There seems to be many factors involved both in reduced and enhanced sexual desire, most of which are unknown. In this review we present some data suggesting that an electroencephalographic analysis of brain activity during exposure to sexually relevant stimuli in male rats and men and during execution of sexual behaviors in male rats may provide useful information. The effects of a commonly used drug, ethanol, on the electroencephalogram recorded during sexual events in rats and men are also described. Although this approach to the analysis of the central nervous activity associated with sexual desire, arousal and behavior is still in its infancy, the data obtained so far show a remarkable similarity between men and rats. This suggests that animal studies of electroencephalographic responses to drugs in sexual contexts may be useful for predicting effects in the human male. PMID:24534418

Forty boys with ASD, 39 with FXS, and 28 with typical development (TD), aged 4–15 years, participated. Boys with FXS were hyperaroused compared to boys with TD but did not differ from boys with ASD. Dampened vagal tone predicted pragmatic impairment in ASD, and associations emerged between cardiac activity and receptive/expressive vocabulary across groups. Findings support autonomic dysfunction as a mechanism underlying pragmatic impairment in ASD and suggest that biophysiological profiles are shared in ASD and FXS, which has implications for understanding the role of fragile X mental retardation-1 (FMR1, the FXS gene) in the pathophysiology of ASD.

    Conflicting evidence exists regarding whether bisexual-identified men are sexually aroused to both men and women. We hypothesized that a distinct characteristic, level of curiosity about sexually diverse acts, distinguishes bisexual-identified men with and without bisexual arousal. Study 1 assessed men's (n=277) sexual arousal via pupil dilation to male and female sexual stimuli. Bisexual men were, on average, higher in their sexual curiosity than other men. Despite this general difference, only bisexual-identified men with elevated sexual curiosity showed bisexual arousal. Those lower in curiosity had responses resembling those of homosexual men. Study 2 assessed men's (n=72) sexual arousal via genital responses and replicated findings of Study 1. Study 3 provided information on the validity on our measure of sexual curiosity by relating it to general curiosity and sexual sensation seeking (n=83). Based on their sexual arousal and personality, at least two groups of men identify as bisexual. PMID:24055219

    The human sexual response to sexually arousing stimuli is a motivational incentive-based cycle comprising subjective experience and physiologic changes. Clinical and empirical data support a circular model of overlapping phases of variable order. Brain imaging data of sexual arousal identify areas of cerebral activation and inhibition reflecting a complex network of cognitive, motivational, emotional, and autonomic components. Psychologic and biologic factors influence the brain's appraisal and processing of sexual stimuli to allow or disallow subsequent arousal. The sexual and non-sexual outcomes influence motivation to future sexual intimacy. Variability is marked both between individuals and within a person's sexual life, influenced by multiple factors, including stage of life cycle, mental health, and relationship happiness. Neurologic disease can interrupt the cycle at many points: by limiting motivation, reducing ability to attend to and feel sexual stimuli, and accomplishing the movements needed to stimulate and experience intercourse. Impairments to genital congestion, penile erection, and orgasm may also occur. Disease-associated changes to the interpersonal relationship and self-image plus frequently comorbid depression will tend to lessen motivation and temper the brain's appraisal of sexual stimuli, so precluding arousal. Therapy begins by explaining the sexual response cycle, clarifying the points of interruption in the patient's own cycle so as to guide treatment. PMID:26003236

    Men's sexually aggressive behavior potentially could relate to either physiological hyporeactivity or hyperreactivity, and these two different physiological profiles could be associated with different underlying causes of sexual aggression. Thus, measurement of physiological reactivity could provide insight into mechanisms relevant to the etiology of sexual aggression. The relationship between sexual aggression and physiological reactivity was investigated in 78 community men (38 sexually aggressive and 40 non-aggressive men). In a laboratory protocol, the men were exposed to neutral, negative-affect-inducing, and positive-affect-inducing stimuli. Men's salivary cortisol concentrations and electrodermal activity (EDA) were measured throughout the laboratory procedure. Sexually aggressive men demonstrated (1) lower overall cortisol levels and (2) lower EDA reactivity in some conditions as compared to non-aggressive men. Results of this study were consistent with the idea that men's sexual aggression is associated with physiological hyporeactivity, a physiological profile that has been found to be associated with externalizing behaviors and psychopathic traits.

    The literature on sexual responses shows a large and not fully understood between-women variance in sexual responses and in strength of coherence between physiological and subjective sexual responses. This study investigated cognitive factors theorized to be associated with sexual responses that could explain such variance. Specifically, we investigated the predictive value of sexual excitation/inhibition and sexual schemas on sexual response and coherence. Vaginal photoplethysmography and continuous subjective sexual arousal were collected from 29 young women while they watched a control/erotic video sequence. Hierarchical linear modeling revealed that high sexual excitation and schemas related to passion and romance were related to higher coherence. These findings support the notion that cognitive factors that enhance sexual arousal contribute to the large variation seen in the coherence of sexual response as measured in the laboratory.

    Among 27,000 infants studied prospectively to characterize their sleep-wake behavior, 38 infants died under 6 months of age. They included 26 cases of sudden infant death syndrome (SIDS). Five infants who died from congenital cardiac abnormalities, two from infected pulmonary dysplasia, two from septic shock with multi-organ failure, one during a prolonged seizure, one from a prolonged neonatal hypoxemia, one from meningitis with brain infarction. All the infants had been recorded during one night in a pediatric sleep laboratory some 3-12 weeks before death. The frequency and duration of sleep apneas were analyzed. The infants' brain stem material was collected and immunohistochemistry of glial fibrillary acidic protein (GFAP) was carried out. The density of GFAP-positive reactive astrocytes was measured in the cardiorespiratory and arousal pathway. Akaike information criterion statistics (AIC) were calculated to elucidate the relationship between the epidemiological data on sleep position, the physiological data and the pathological data in SIDS victims. The duration of obstructive apnea was the most significant variable to differentiate between SIDS victims and control infants. In conclusion, the present study sustains the possibility of an organic fragility within the arousal pathway in SIDS victims with repetitive sleep apneas. PMID:12350297

    Objective This study used functional magnetic resonance imaging (fMRI) to contrast the differential brain activation patterns in response to visual stimulation with both male and female erotic nude pictures in male-to-female (MTF) transsexuals who underwent a sex reassignment surgery. Materials and Methods A total of nine healthy MTF transsexuals after a sex reassignment surgery underwent fMRI on a 3.0 Tesla MR Scanner. The brain activation patterns were induced by visual stimulation with both male and female erotic nude pictures. Results The sex hormone levels of the postoperative MTF transsexuals were in the normal range of healthy heterosexual females. The brain areas, which were activated by viewing male nude pictures when compared with viewing female nude pictures, included predominantly the cerebellum, hippocampus, putamen, anterior cingulate gyrus, head of caudate nucleus, amygdala, midbrain, thalamus, insula, and body of caudate nucleus. On the other hand, brain activation induced by viewing female nude pictures was predominantly observed in the hypothalamus and the septal area. Conclusion Our findings suggest that distinct brain activation patterns associated with visual sexual arousal in postoperative MTF transsexuals reflect their sexual orientation to males.

    During the postpartum period, women experience significant changes in their neuroendocrine profiles and social behavior compared to before pregnancy. A common experience with motherhood is a decrease in sexual desire. Although the lifestyle and peripheral physiological changes associated with parturition might decrease a woman’s sexual interest, we hypothesized that there are also hormone-mediated changes in women’s neural response to sexual and infant stimuli with altered reproductive priorities. We predicted that amygdala activation to sexually arousing stimuli would be suppressed in postpartum versus nulliparous women, and altered with intranasal oxytocin administration. To test this, we measured amygdala activation using fMRI in response to sexually arousing pictures, infant pictures, and neutral pictures in 29 postpartum and 30 nulliparous women. Half of the women received a dose of exogenous oxytocin before scanning. As predicted, nulliparous women subjectively rated sexual pictures to be more arousing, and infant pictures to be less arousing, than did postpartum women. However, nulliparous women receiving the nasal oxytocin spray rated the infant photos as arousing as did postpartum women. Right amygdala activation was lower in postpartum versus nulliparous women in response to sexual, infant, and neutral images, suggesting a generalized decrease in right amygdala responsiveness to arousing images with parturition. There was no difference in right amygdala activation with nasal spray application. Postpartum women therefore appear to experience a decrease in sexual interest possibly as a feature of a more generalized decrease in amygdala responsiveness to arousing stimuli. PMID:23085496

    2008-01-01

    The locus coeruleus (LC), the major noradrenergic nucleus of the brain, gives rise to fibres innervating most structures of the neuraxis. Recent advances in neuroscience have helped to unravel the neuronal circuitry controlling a number of physiological functions in which the LC plays a central role. Two such functions are the regulation of arousal and autonomic activity, which are inseparably linked largely via the involvement of the LC. Alterations in LC activity due to physiological or pharmacological manipulations or pathological processes can lead to distinct patterns of change in arousal and autonomic function. Physiological manipulations considered here include the presentation of noxious or anxiety-provoking stimuli and extremes in ambient temperature. The modification of LC-controlled functions by drug administration is discussed in detail, including drugs which directly modify the activity of LC neurones (e.g., via autoreceptors, storage, reuptake) or have an indirect effect through modulating excitatory or inhibitory inputs. The early vulnerability of the LC to the ageing process and to neurodegenerative disease (Parkinson’s and Alzheimer’s diseases) is of considerable clinical significance. In general, physiological manipulations and the administration of stimulant drugs, ?2-adrenoceptor antagonists and noradrenaline uptake inhibitors increase LC activity and thus cause heightened arousal and activation of the sympathetic nervous system. In contrast, the administration of sedative drugs, including ?2-adrenoceptor agonists, and pathological changes in LC function in neurodegenerative disorders and ageing reduce LC activity and result in sedation and activation of the parasympathetic nervous system.

    Prenatal auditory stimulation in chicks with species-specific sound and music at 65 dB facilitates spatial orientation and learning and is associated with significant morphological and biochemical changes in the hippocampus and brainstem auditory nuclei. Increased noradrenaline level due to physiological arousal is suggested as a possible mediator for the observed beneficial effects following patterned and rhythmic sound exposure. However, studies regarding the effects of prenatal high decibel sound (110 dB; music and noise) exposure on the plasma noradrenaline level, synaptic protein expression in the hippocampus and spatial behavior of neonatal chicks remained unexplored. Here, we report that high decibel music stimulation moderately increases plasma noradrenaline level and positively modulates spatial orientation, learning and memory of one day-old chicks. In contrast, noise at the same sound pressure level results in excessive increase of plasma noradrenaline level and impairs the spatial behavior. Further, to assess the changes at the molecular level, we have quantified the expression of functional synapse markers: synaptophysin and PSD-95 in the hippocampus. Compared to the controls, both proteins show significantly increased expressions in the music stimulated group but decrease in expressions in the noise group. We propose that the differential increase of plasma noradrenaline level and altered expression of synaptic proteins in the hippocampus are responsible for the observed behavioral consequences following prenatal 110 dB music and noise stimulation.

  6. Sex Differences in Response to Visual Sexual Stimuli: A Review

    2009-01-01

    This article reviews what is currently known about how men and women respond to the presentation of visual sexual stimuli. While the assumption that men respond more to visual sexual stimuli is generally empirically supported, previous reports of sex differences are confounded by the variable content of the stimuli presented and measurement techniques. We propose that the cognitive processing stage of responding to sexual stimuli is the first stage in which sex differences occur. The divergence between men and women is proposed to occur at this time, reflected in differences in neural activation, and contribute to previously reported sex differences in downstream peripheral physiological responses and subjective reports of sexual arousal. Additionally, this review discusses factors that may contribute to the variability in sex differences observed in response to visual sexual stimuli. Factors include participant variables, such as hormonal state and socialized sexual attitudes, as well as variables specific to the content presented in the stimuli. Based on the literature reviewed, we conclude that content characteristics may differentially produce higher levels of sexual arousal in men and women. Specifically, men appear more influenced by the sex of the actors depicted in the stimuli while women’s response may differ with the context presented. Sexual motivation, perceived gender role expectations, and sexual attitudes are possible influences. These differences are of practical importance to future research on sexual arousal that aims to use experimental stimuli comparably appealing to men and women and also for general understanding of cognitive sex differences.

    Stress and anxiety are commonly thought to be detrimental to sexual function. Several studies in both the human and animal literature, however, have found that inducing anxiety can enhance sexual function in women. The mechanisms that explain a negative relationship between physical and psychological stress and sexual functioning are well documented, but little is known about how stress or anxiety might have a facilitatory effect on sexual arousal. As an initial step in exploring the relationship between anxiety and sexual arousal, the present study examined the role of the autonomic nervous system, and the adrenal hormones cortisol and dehydroepiandrosterone-sulfate (DHEA-S) in response to a sexual film, an anxiety-inducing film, and a humorous film. Nineteen premenopausal women (mean age 24.4 years) who were free from sexual difficulties came into the lab on three separate days. At each session they were shown an anxiety-inducing, sexually arousing, or humorous (control) film while their physiological arousal was measured. They also provided saliva samples before and after each film. Cortisol significantly decreased, while DHEA-S increased in the sexual and humorous conditions. Neither hormone changed significantly in the anxiety-inducing condition. Autonomic nervous system activity measured by heart rate and heart rate variability did not change in response to the sexual or anxiety-inducing films, but heart rate variability increased significantly in response to the humorous film. The cortisol/DHEA-S ratio at the post-sexual film time point was significantly negatively correlated with genital arousal (measured by vaginal pulse amplitude). Anxiety-inducing films did not result in a physiological stress response, which can explain why they do not impair sexual function. PMID:21195074

    Nowadays, the idea of a reciprocal influence of physiological and psychological processes seems to be widely accepted. For instance, current theories of embodied emotion suggest that knowledge about an emotion concept involves simulations of bodily experienced emotional states relevant to the concept. In line with this framework, the present study investigated whether actual levels of physiological arousal interact with the processing of emotional words. Participants performed 2 blocks of an attentional blink task, once after a cycling session (increased arousal) and once after a relaxation session (reduced arousal). Concretely, participants were instructed to detect and report 2 target words (T1 and T2) presented among a series of nonword distractors. T1 and T2 were either neutral, high arousal, or low arousal words. Results revealed that increased physiological arousal led to improved reports of high arousal T2 words, whereas reduced physiological arousal led to improved reports of low arousal T2 words. Neutral T2 remained unaffected by the arousing conditions. These findings emphasize that actual levels of physiological arousal modulate the cognitive access to arousal (in-)congruent emotional concepts and suggest a direct grounding of emotion knowledge in our bodily systems of arousal.

    Affective and cognitive factors play an important role in the activation and regulation of men's sexual arousal. Barlow (1986) argued that initial affective reactions determine the allocation of attention to sexual stimuli. We applied Barlow's model to our understanding of the role of sexual arousal in sexual orientation, where sexual arousal patterns have consistently been found to be congruent with self-reported orientation in men, but not in women. Visual attention of 28 heterosexual and 22 homosexual men to same- and opposite-sex erotic stimuli was assessed and experimentally-directed by means of a newly developed software application, while genital (penile rigidity) and affective responses (self-reported and physiological) were measured. In line with previous research, we found "category specificity" in men's sexual arousal, in that sexual responses were strongest to orientation-congruent stimuli. Also, both homosexual and heterosexual men experienced stronger sexual responses to conditions in which their attention was directed to sexual versus nonsexual content of orientation-congruent stimuli. Only homosexual men manifested higher sexual responses when their visual attention was directed towards the sexual content of orientation-incongruent stimuli. Heterosexual men experienced weaker positive and stronger negative affective responses to orientation-incongruent content, suggestive of potential avoidance or inhibitory mechanisms. PMID:24473940

    Sexual dysfunction affects both men and women, involving organic disorders, psychological problems, or both. Overall, the state of our knowledge is less advanced regarding female sexual physiology in comparison with male sexual function. Female sexual dysfunction has received little clinical and basic research attention and remains a largely untapped field in medicine. The epidemiology of female sexual dysfunction is poorly understood because relatively few studies have been done in community settings. In the United States, female sexual dysfunction has been estimated to affect 40% of women in the general population. Among the elderly, however, it has been reported that up to 87% of women complain of sexual dissatisfaction. Several studies have shown that the prevalence of female sexual arousal disorders correlates significantly with increasing age. These studies have shown that sexual arousal and frequency of coitus in the female decreases with increasing age. The pathophysiology of female sexual dysfunction appears more complex than that of males, involving multidimensional hormonal, neurological, vascular, psychological, and interpersonal aspects. Organic female sexual disorders may include a wide variety of vascular, neural, or neurovascular factors that lead to problems with libido, lubrication, and orgasm. However, the precise etiology and mechanistic pathways of age-related female sexual arousal disorders are yet to be determined. In the past two decades, some advances have been made in exploring the basic hemodynamics and neuroregulation of female sexual function and dysfunction in both animal models and in human studies. In this review, we summarize neural regulation of sexual function and neurological causes of sexual dysfunction in women. PMID:20664775

    Sensory perception can modulate aging and physiology across taxa. We found that perception of female sexual pheromones through a specific gustatory receptor expressed in a subset of foreleg neurons in male fruit flies, Drosophila melanogaster, rapidly and reversibly decreases fat stores, reduces resistance to starvation, and limits life span. Neurons that express the reward-mediating neuropeptide F are also required for pheromone effects. High-throughput whole-genome RNA sequencing experiments revealed a set of molecular processes that were affected by the activity of the longevity circuit, thereby identifying new candidate cell-nonautonomous aging mechanisms. Mating reversed the effects of pheromone perception; therefore, life span may be modulated through the integrated action of sensory and reward circuits, and healthy aging may be compromised when the expectations defined by sensory perception are discordant with ensuing experience.

    Evolutionary-minded developmentalists studying predictive-adaptive-response processes linking childhood adversity with accelerated female reproductive development and health scientists investigating the developmental origins of health and disease (DOoHaD) may be tapping the same process, whereby longer-term health costs are traded off for increased probability of reproducing before dying via a process of accelerated reproductive maturation. Using data from 73 females, we test the following propositions using path analysis: (a) greater exposure to prenatal stress predicts greater maternal depression and negative parenting in infancy, (b) which predicts elevated basal cortisol at 4.5 years, (c) which predicts accelerated adrenarcheal development, (d) which predicts more physical and mental health problems at age 18. Results prove generally consistent with these propositions, including a direct link from cortisol to mental health problems. DOoHaD investigators should consider including early sexual maturation as a core component linking early adversity and stress physiology with poor health later in life in females.

    Ginkgo biloba extract (GBE) facilitates blood flow, influences nitric oxide systems, and has a relaxant effect on smooth muscle tissue. These processes are important to the sexual response in women and, hence, it is feasible that GBE may have a therapeutic effect. The present study was the first to provide an empirical examination of the effects of both short- and long-term GBE administration on subjective and physiological (vaginal photoplethysmography) measures of sexual function in women with Sexual Arousal Disorder. A single dose of 300 mg GBE had a small but significant facilitatory effect on physiological, but not subjective, sexual arousal compared to placebo in 99 sexually dysfunctional women. The long-term effects of GBE on sexual function were assessed in 68 sexually dysfunctional women who were randomly assigned to 8 weeks treatment of either (1) GBE (300 mg/daily), (2) placebo, (3) sex therapy which focused on training women to attend to genital sensations, or (4) sex therapy plus GBE. When combined with sex therapy, but not alone, long-term GBE treatment significantly increased sexual desire and contentment beyond placebo. Sex therapy alone significantly enhanced orgasm function compared with placebo. Long-term GBE administration did not significantly enhance arousal responses beyond placebo. It was concluded that (1) neither short- or long-term administration of GBE alone substantially impacts sexual function in women, (2) a substantial placebo effect on sexual function exists in women with sexual concerns, and (3) teaching women to focus on genital sensations during sex enhances certain aspects of women’s sexual functioning.

    2015-02-01

    Studies involving genetic engineering on animal models and mathematical analysis of cardiovascular signals on humans are shedding new light on the interactions between the arterial baroreceptor reflex (baroreflex) and arousal. Baroreceptor stimulation, if very mild or performed under anaesthesia, may inhibit cortical arousal. However, substantial increases or decreases in baroreflex activation cause arousal in animal models and human subjects in physiological conditions. On the other hand, cardiovascular changes during autonomic arousals and between the states of wakefulness and sleep involve changes in the baroreflex set point and balance with central autonomic commands. Neural connectivity and functional data suggest that the nucleus of the solitary tract, adrenergic C1 neurons of the medulla, and the parabrachial nucleus of the pons mediate the bidirectional interactions between the baroreflex and arousal. These interactions may constitute a positive feedback loop that facilitates sharp and coordinated brain state and autonomic transitions upon arousal: upon arousal, central autonomic commands may increase blood pressure, thereby loading baroreceptors and further increasing arousal. Anomalies of this feedback loop may play a role in the pathophysiology of disease conditions associated with cardiovascular and sleep-wake cycle alterations. These conditions include: obstructive sleep apnoea syndrome, with its association with excessive daytime sleepiness and baroreflex impairment; and insomnia, with its association with autonomic hyperarousal and hypertension. When faced with disorders associated with cardiovascular and sleep-wake cycle alterations, clinical reasoning should entertain the possibility that both conditions are strongly influenced by anomalies of baroreflex function.

    Study Objectives: The effect of common sedatives on upper airway physiology and breathing during sleep in obstructive sleep apnea (OSA) has been minimally studied. Conceptually, certain sedatives may worsen OSA in some patients. However, sleep and breathing could improve with certain sedatives in patients with OSA with a low respiratory arousal threshold. This study aimed to test the hypothesis that trazodone increases the respiratory arousal threshold in patients with OSA and a low arousal threshold. Secondary aims were to examine the effects of trazodone on upper airway dilator muscle activity, upper airway collapsibility, and breathing during sleep. Design: Patients were studied on 4 separate nights according to a within-subjects cross-over design. Setting: Sleep physiology laboratory. Patients: Seven patients with OSA and a low respiratory arousal threshold. Interventions: In-laboratory polysomnograms were obtained at baseline and after 100 mg of trazodone was administered, followed by detailed overnight physiology experiments under the same conditions. During physiology studies, continuous positive airway pressure was transiently lowered to measure arousal threshold (negative epiglottic pressure prior to arousal), dilator muscle activity (genioglossus and tensor palatini), and upper airway collapsibility (Pcrit). Measurements and Results: Trazodone increased the respiratory arousal threshold by 32 ± 6% (-11.5 ± 1.4 versus -15.3 ± 2.2 cmH2O, P < 0.01) but did not alter the apnea-hypopnea index (39 ± 12 versus 39 ± 11 events/h sleep, P = 0.94). Dilator muscle activity and Pcrit also did not systematically change with trazodone. Conclusions: Trazodone increases the respiratory arousal threshold in patients with obstructive sleep apnea and a low arousal threshold without major impairment in dilator muscle activity or upper airway collapsibility. However, the magnitude of change in arousal threshold was insufficient to overcome the compromised upper airway anatomy in these patients. Citation: Eckert DJ; Malhotra A; Wellman A; White DP.

    Physiological correlates of behavioral and emotional problems, substance use onset and initiation of risky sexual behavior have not been studied in adolescents with prenatal drug exposure. We studied the concordance between baseline respiratory sinus arrhythmia (RSA) at age 3 and baseline Cortisol levels at age 11. We hypothesized that children who showed concordance between RSA and Cortisol would have lower neurobehavioral disinhibition scores which would in turn predict age of substance use onset and first sexual intercourse. The sample included 860 children aged 16 years participating in the Maternal Lifestyle Study, a multisite longitudinal study of children with prenatal exposure to cocaine and other substances. Structural equation modeling was used to test pathways between prenatal substance exposure, early adversity, baseline RSA, baseline Cortisol, neurobehavioral disinhibition, drug use, and sexual behavior outcomes. Concordance was studied by examining separate male and female models in which there were statistically significant interactions between baseline RSA and Cortisol. Prenatal substance exposure was operationalized as the number of substances to which the child was exposed. An adversity score was computed based on caregiver postnatal substance use, depression and psychological distress, number of caregiver changes, socioeconomic and poverty status, quality of the home environment, and child history of protective service involvement, abuse and neglect. RSA and Cortisol were measured during a baseline period prior to the beginning of a task. Neurobehavioral disinhibition, based on composite scores of behavioral dysregulation and executive dysfunction, substance use and sexual behavior were derived from questionnaires and cognitive tests administered to the child. Findings were sex specific. In females, those with discordance between RSA and Cortisol (high RSA and low Cortisol or low RSA and high Cortisol) had the most executive dysfunction which, in turn, predicted earlier initiation of alcohol by age 16. Among boys, there also existed a significant baseline RSA by baseline Cortisol interaction. Boys with low baseline RSA and high baseline Cortisol had the highest levels of behavioral dysregulation. This increase in behavioral dysregulation was in turn related to initiation of alcohol use by age 16 and lower age of first sexual intercourse. We found sex-specific pathways to the initiation of alcohol use and risky sexual behavior through the combined activity of parasympathetic and neuroendocrine functioning. The study of multiple physiological systems may suggest new pathways to the study of age of onset of substance use and engagement in risky sexual behavior in adolescents. PMID:25033835

The study of multiple physiological systems may suggest new pathways to the study of age of onset of substance use and engagement in risky sexual behavior in adolescents. PMID:25033835

    Persistent genital arousal disorder (PGAD) is not well known or adequately understood by physicians. PGAD is characterized by a persistent and highly unwanted state of genital arousal and orgasm-like feelings. “Ghusl” is an ablution in Islamic culture, which is an obligatory ritual wherein the body is washed thoroughly after exposure to “religious contaminants,” such as sexual intercourse, menstruation, and childbirth.

    Persistent Genital Arousal Disorder (PGAD) refers to the experience of persistent sensations of genital arousal that are felt to be unprovoked, intrusive and unrelieved by one or several orgasms. It is often mistaken for hypersexuality since PGAD often results in a high frequency of sexual behaviour. At present little is known with certainty about the etiology of this condition. We

    According to life history theory, environmental cues indicating that one's future survivability is low increase reproductive effort. This suggests that exposure to low survivability cues will increase people's preparedness to engage in sex. However, according to sexual selection theory and parental investment theory, evolutionary pressures favored a more conservative sexual strategy among women compared to men.

    "Anatomy is destiny": Sigmund Freud viewed human anatomy as a necessary, although not a sufficient, condition for understanding the complexity of human sexual function with a solid biologic basis. The aim of the chapter is to describe women's genital anatomy and physiology, focusing on women's sexual function with a clinically oriented vision. Key points include: embryology, stressing that the "female" is the anatomic "default" program, differentiated into "male" only in the presence of androgens at physiologic levels for the gestational age; sex determination and sex differentiation, describing the interplay between anatomic and endocrine factors; the "clitoral-urethral-vaginal" complex, the most recent anatomy reading of the corpora cavernosa pattern in women; the controversial G spot; the role of the pelvic floor muscles in modulating vaginal receptivity and intercourse feelings, with hyperactivity leading to introital dyspareunia and contributing to provoked vestibulodynia and recurrent postcoital cystitis, whilst lesions during delivery reduce vaginal sensations, genital arousability, and orgasm; innervation, vessels, bones, ligaments; and the physiology of women's sexual response. Attention to physiologic aging focuses on "low-grade inflammation," genital and systemic, with its impact on women sexual function, especially after the menopause, if the woman does not or cannot use hormone replacement therapy.

    Many people watch sexually arousing material on the Internet in order to receive sexual arousal and gratification. When browsing for sexual stimuli, individuals have to make several decisions, all possibly leading to positive or negative consequences. Decision-making research has shown that decisions under ambiguity are influenced by consequences received following earlier decisions. Sexual arousal might interfere with the decision-making process and should therefore lead to disadvantageous decision-making in the long run. In the current study, 82 heterosexual, male participants watched sexual pictures, rated them with respect to sexual arousal, and were asked to indicate their current level of sexual arousal before and following the sexual picture presentation. Afterwards, subjects performed one of two modified versions of the Iowa Gambling Task in which sexual pictures were displayed on the advantageous and neutral pictures on the disadvantageous card decks or vice versa (n = 41/n = 41). Results demonstrated an increase of sexual arousal following the sexual picture presentation. Decision-making performance was worse when sexual pictures were associated with disadvantageous card decks compared to performance when the sexual pictures were linked to the advantageous decks. Subjective sexual arousal moderated the relationship between task condition and decision-making performance. This study emphasized that sexual arousal interfered with decision-making, which may explain why some individuals experience negative consequences in the context of cybersex use. PMID:23733155

    2015-05-01

    In the social psychological threat-compensation literature, there is an apparent contradiction whereby relatively extreme beliefs both decrease markers of physiological arousal following meaning violations, and increase the values affirmation behaviors understood as a palliative responses to this arousal. We hypothesize that this is due to the differential impact of measuring extremism on behavioral inhibition and approach systems following meaning violations, whereby extremism both reduces markers of conflict arousal (BIS) and increases values affirmation (BAS) unrelated to this initial arousal. Using pupil dilation as a proxy for immediate conflict arousal, we found that the same meaning violation (anomalous playing cards) evoked greater pupil dilation, and that this pupillary reaction was diminished in participants who earlier reported extreme beliefs. We also found that reporting extreme beliefs was associated with greater affirmation of an unrelated meaning framework, where this affirmation was unrelated to physiological markers of conflict arousal.

    Strokes are the second leading cause of death and the third leading cause of disability worldwide. Thanks in part to better and more available diagnosis, treatment, and rehabilitation, the vast majority of stroke patients tend to survive strokes, particularly in the industrialized world. Motor disability and cognitive changes such as aphasia and visuospatial disorders are most often considered among the major contributors to stroke burden. This chapter discusses disorders of sexual functions as another frequent sequel of strokes. Strokes generally induce hyposexuality, but in some instances they may be followed by hypersexuality. There is some evidence suggesting that lesions of either hemisphere affect sexual activities, but for different reasons: aphasia and depression after left-hemisphere lesions, a deficit in arousal and perhaps visuospatial disorders after right-hemisphere lesions. Psychologic, psychosocial, and physical factors, as well as medications, play an important role. A better understanding of the psychosocial and physiologic mechanisms underlying sexual functioning can provide insight into improving sexual activity and therefore quality of life in patients affected by strokes and other brain lesions.

    The attentional myopia model of behavioral control (Mann & Ward, 2007) was tested in an experiment investigating the relationship between physiological arousal and aggression. Drawing on previous work linking arousal and narrowed attentional focus, the model predicts that arousal will lead to behavior that is relatively disinhibited in situations in which promoting pressures to aggress are highly salient. In situations in which inhibitory pressures are more salient, the model predicts behavior that is relatively restrained. In the experiment, 81 male undergraduates delivered noise-blasts against a provoking confederate while experiencing either high or low levels of physiological arousal and, at the same time, being exposed to cues that served either to promote or inhibit aggression. In addition to supporting the predictions of the model, this experiment provided some of the first evidence for enhanced control of aggression under conditions of heightened physiological arousal. Implications for interventions designed to reduce aggression are discussed. PMID:18561301

    2014-01-01

    A wealth of animal and human studies demonstrate that early life environment significantly influences adult metabolic balance, however the etiology for offspring metabolic misprogramming remains incompletely understood. Here, we determine the effect of maternal diet per se on offspring sex-specific outcomes in metabolic health and hypothalamic transcriptome regulation in mice. Furthermore, to define developmental periods of maternal diet misprogramming aspects of offspring metabolic balance, we investigated offspring physiological and transcriptomic consequences of maternal high-fat/high-sugar diet feeding during pregnancy and/or lactation. We demonstrate that female offspring of high-fat/high-sugar diet-fed dams are particularly vulnerable to metabolic perturbation with body weight increases due to postnatal processes, whereas in utero effects of the diet ultimately lead to glucose homeostasis dysregulation. Furthermore, glucose- and maternal-diet sensitive gene expression modulation in the paraventricular hypothalamus is strikingly sexually dimorphic. In summary, we uncover female-specific, maternal diet-mediated in utero misprogramming of offspring glucose homeostasis and a striking sexual dimorphism in glucose- and maternal diet-sensitive paraventricular hypothalamus gene expression adjustment. Notably, female offspring metabolic vulnerability to maternal high-fat/high-sugar diet propagates a vicious cycle of obesity and type 2 diabetes in subsequent generations. PMID:24684305

    Women with a history of childhood sexual abuse (CSA) are at greater risk for experiencing sexual problems in their adult lives. Yet, little is known about the possible role of cognitive and affective mechanisms in the development of sexual arousal difficulties in this population. This study investigated the role of pre-existing affect (affect prior to exposure to sexual stimuli) on genital responses, subjective sexual arousal, and affect elicited during the presentation of erotic film excerpts in a community sample of 25 women with and 25 women without a history of CSA. The CSA group showed greater pre-existing negative affect and smaller genital responses to the erotic film stimuli compared to the NSA group. Findings support a moderating effect of CSA, in that pre-existing negative affect was associated with strength of genital responses in the NSA but not in the CSA group. The results did not support a mediation model of pre-existing negative affect as an explanation for smaller physiological sexual responses in the CSA group. Taken together, the findings suggest that pre-existing affect may be more relevant for women with no history of CSA and call for more research on factors implicated in impaired sexual responses in women with a history of CSA.

    Persistent genital arousal disorder (PGAD) is characterized by intrusive sexual arousal that is unresolvable via sexual activity and persists for an extended period of time. PGAD's etiology is unknown, and it has no established treatments. This case study reports on a 71-year-old female patient diagnosed with PGAD who received 9 sessions of hypnotherapy. The following measures were administered at baseline and follow-up: Hospital Anxiety and Depression Scale, Center for Epidemiologic Studies Depression Scale, Pittsburgh Sleep Quality Index, and visual analogue measurements of quality of life, intensity of symptoms, and marital interference. At follow-up, there were significant improvements in all measures. Given the currently limited alternatives for treatment, this case study suggests that hypnotherapy may be beneficial for some patients with PGAD. PMID:24568327

    N-Acylhomoserine lactone (AHL)-mediated quorum-sensing (QS) regulates virulence functions in plant and animal pathogens such as Agrobacterium tumefaciens and Pseudomonas aeruginosa. A chemolibrary of more than 3500 compounds was screened using two bacterial AHL-biosensors to identify QS-inhibitors (QSIs). The purity and structure of 15 QSIs selected through this screening were verified using HPLC MS/MS tools and their activity tested on the A. tumefaciens and P. aeruginosa bacterial models. The IC50 value of the identified QSIs ranged from 2.5 to 90 µg/ml, values that are in the same range as those reported for the previously identified QSI 4-nitropyridine-N-oxide (IC50 24 µg/ml). Under the tested culture conditions, most of the identified QSIs did not exhibit bacteriostatic or bactericidal activities. One third of the tested QSIs, including the plant compound hordenine and the human sexual hormone estrone, decreased the frequency of the QS-regulated horizontal transfer of the tumor-inducing (Ti) plasmid in A. tumefaciens. Hordenine, estrone as well as its structural relatives estriol and estradiol, also decreased AHL accumulation and the expression of six QS-regulated genes (lasI, lasR, lasB, rhlI, rhlR, and rhlA) in cultures of the opportunist pathogen P. aeruginosa. Moreover, the ectopic expression of the AHL-receptors RhlR and LasR of P. aeruginosa in E. coli showed that their gene-regulatory activity was affected by the QSIs. Finally, modeling of the structural interactions between the human hormones and AHL-receptors LasR of P. aeruginosa and TraR of A. tumefaciens confirmed the competitive binding capability of the human sexual hormones. This work indicates potential interferences between bacterial and eukaryotic hormonal communications. PMID:24376718

    Introduction The question of whether removal of sensory receptors in the prepuce by circumcision affects sensitivity and/or sexual pleasure is often debated. Aims To examine histological correlates relevant to penile sensitivity and sexual pleasure. Methods Systematic review of the scientific literature on penile structures that might affect sensitivity and sexual sensation. Articles were included if they contained original data on human male penile histology or anatomy. Individual articles, including reference lists, were evaluated. They were then considered in relation to physiological data from articles retrieved by a previous systematic review. Results We retrieved 41 publications on penile structure. Considered in the light of 12 reporting physiological measurements, our evaluation finds that sexual response is unlikely to involve Meissner’s corpuscles, whose density in the prepuce diminishes at the time of life when male sexual activity is increasing. Free nerve endings also show no correlation with sexual response. Because tactile sensitivity of the glans decreases with sexual arousal, it is unrelated to sexual sensation. Thermal sensitivity seems part of the reward mechanism of intercourse. Vibrational sensitivity is not related to circumcision status. Observations that penile sexual sensation is higher post circumcision are consistent with greater access of genital corpuscles to sexual stimuli after removal of the prepuce. This is based on the distribution of these corpuscles (which are located in the glans) and, in uncircumcised men, the position of the retracted prepuce during intercourse, rather than any change in the number of genital corpuscles. The scientific literature suggests that any sexual effect of circumcised men may depend solely on exposure of the glans and not on the absence of the prepuce. Conclusion Based on histological findings and correlates of sexual function, loss of the prepuce by circumcision would appear to have no adverse effect on sexual pleasure. Our evaluation supports overall findings from physiological measurements and survey data. PMID:26185672

Relative to the comparison group, for whom a greater increase in skin conductance was associated with poor arithmetic performance and less risk taking behavior, females with fragile X displayed a minimal increase in heart activity that was nevertheless associated with poor performance on mental arithmetic. In contrast, no arousal–cognitive performance relationship emerged for the group with Turner syndrome. Taken together, our findings suggest that distinct profiles of arousal modulation might be associated with cognitive deficits in these syndrome populations. PMID:17340202

    The neurophysiology and antennal lobe projections of olfactory receptor neurons (ORNs) within sexually isomorphic short trichoid sensilla of male Heliothis virescens (Noctuidae: Lepidoptera) were investigated using cut-sensillum recording and cobalt-lysine staining. A total of 202 sensilla were sorted into 14 possible sensillar categories based on odor responses and physiology of ORNs within. Seventy-two percent of the sensilla identified contained ORNs stimulated by conspecific odors. In addition, a large number of ORNs were specifically sensitive to ss-caryophyllene, a plant-derived volatile (N = 41). Axons originating from ORNs associated with individual sensilla were stained with cobalt lysine (N = 67) and traced to individual glomeruli in the antennal lobe. ORNs with responses to female sex pheromone components exhibited similar axonal projections as those previously described from ORNs in long sensilla trichodea in male H. virescens. Antennal lobe axonal arborizations of ORNs sensitive to hairpencil components were also located in glomeruli near the base of the antennal nerve, whilst those sensitive to plant odorants projected to more medial glomeruli. Comparisons with ORNs described from female H. virescens supports the notion that glomeruli at the base of the antennal nerve are associated with conspecific and interspecific odorants, whereas those located medially are associated with plant volatiles.

    In this experimental study, we investigated how recalling positive, negative, and affectively neutral autobiographic sexual experiences in their personal history affected the current sexual response of sexually functional male volunteers. Based on an attentional-capacity account of sexual arousal, we predicted that affectively charged autobiographic sexual memory recall, both with negative and positive valence, would negatively impact genital arousal, compared to recalling affectively neutral sexual experiences. We expected that subjective sexual arousal would not be differentially affected by emotional memory valence. We measured subjective and genital response to erotic video fragments in sexually functional volunteers (N = 24) in a within-subjects, repeated-measures design. For the memory manipulation, participants received instructions to visualize and mentally re-experience positive, negative, and neutral sexual episodes from autobiographic memory. Memory instructions were found to result in the expected affective states. As predicted, compared to recalling neutral memory, mean genital response was significantly lower during recalling positive and negative memory. However, contrary to prediction, subjective sexual arousal was affected, when multilevel analysis was performed, including a time effect. The implications of the findings were discussed with respect to the advancement of theory and therapeutic intervention. PMID:23519590

    Little is known with certitude about the triggers of persistent genital arousal disorder (PGAD) in women, although there appears to be certain common features of the disorder. Women complain of unbidden feelings of genital arousal that are qualitatively different from sexual arousal that is preceded by sexual desire/and or subjective arousal. The majority of women find PGAD distressing and report only brief relief with orgasm. In this article, we describe five women who believe they developed PGAD either after withdrawing from selective serotonin reuptake inhibitor (SSRI) anti-depressants or while using them. We discuss these sexual symptoms in relation to what is already known about prolonged SSRI withdrawal syndromes and the possible etiologies of these conditions. While not a common cause of PGAD, it is possible that use of, and withdrawal from, pharmacological agents contributes to the development of PGAD. PMID:18224549

    Individuals attempting to label their emotions look for a plausible source of their physiological arousal. Co-occurrence of plausible sources can lead to the misattribution of real (or bogus) physiological arousal, resulting in physically attractive individuals being perceived as more attractive than they actually are. In two experiments, female participants heard bogus heart rate feedback while viewing photos of attractive male models. Compared with low-power and control participants, high-power participants rated reinforced photos (increased heart rate) more attractive than non-reinforced photos (stable heart rate) to a greater extent when they heard their own bogus heart rate feedback (Experiments 1 and 2) and to a lesser extent when they heard a recording of another participant's heart rate (Experiment 2). These findings, which suggest that power increases the tendency to misattribute one's physiological arousal to physically attractive individuals, are discussed with reference to theories linking power and social perception.

The hypotheses emerging from these theories were evaluated through a critical analysis of several areas of research including habituation of arousal to erotic stimuli, preferences regarding number of sexual partners, the effect of long-term monogamous relationships on sexual arousal and desire, and prevalence and risk factors associated with extradyadic behavior. The current literature best supports the predictions made by sexual strategies theory in that sexual functioning has evolved to promote short-term mating. Sexual arousal and desire appear to decrease in response to partner familiarity and increase in response to partner novelty in men and women. Evidence to date suggests this effect may be greater in men. PMID:25222339

    Individuals who are high in rape myth acceptance (RMA) have been found to report a high proclivity to rape. In a series of three studies, the authors examined whether the relationship between RMA and self-reported rape proclivity was mediated by anticipated sexual arousal or anticipated enjoyment of sexually dominating the rape victim.

    Arousal protects against the adverse and potentially fatal effects of asphyxia during sleep. Asphyxia stimulates the carotid bodies and central chemoreceptors but the sequence of events leading to arousal is uncertain. In this review, the theoretical mechanisms leading to arousal from sleep are briefly summarized and the issue of whether central respiratory chemoreceptors (CRCs) or other types of CO2-responsive CNS neurons contribute to asphyxia-induced arousal is discussed. We focus on the role of the retrotrapezoid nucleus, the raphe and the locus coeruleus and emphasize the anatomical and neurophysiological evidence which suggests that these putative central chemoreceptors could contribute to arousal independently of their effects on breathing. Finally, we describe recent attempts to test the contribution of specific brainstem pathways to asphyxia-induced arousal using optogenetic and other tools and the possible contribution of a group of hypoxia-sensitive brainstem neurons (the C1 cells) to breathing and arousal.

    Four experiments revealed arousal-enhanced location memory for pictures. After an incidental encoding task, participants were more likely to remember the locations of positive and negative arousing pictures than the locations of non-arousing pictures, indicating better binding of location to picture. This arousal-enhanced binding effect did not have a cost for the binding of nearby pictures to their locations. Thus, arousal can enhance binding of an arousing picture’s content to its location without interfering with picture-location binding for nearby pictures. In addition, arousal-enhanced picture-location memory binding is not just a side effect of enhanced memory for the picture itself, as it occurs both when recognition memory is good and when it is poor.

  8. The influence of atypical antipsychotic drugs on sexual function

    Human sexuality is contingent upon many biological and psychological factors. Such factors include sexual drive (libido), physiological arousal (lubrication/erection), orgasm, and ejaculation, as well as maintaining normal menstrual cycle. The assessment of sexual dysfunction can be difficult due to the intimate nature of the problem and patients’ unwillingness to discuss it. Also, the problem of dysfunction is often overlooked by doctors. Atypical antipsychotic treatment is a key component of mental disorders’ treatment algorithms recommended by the National Institute of Health and Clinical Excellence, the American Psychiatric Association, and the British Society for Psychopharmacology. The relationship between atypical antipsychotic drugs and sexual dysfunction is mediated in part by antipsychotic blockade of pituitary dopamine D2 receptors increasing prolactin secretion, although direct correlations have not been established between raised prolactin levels and clinical symptoms. Variety of mechanisms are likely to contribute to antipsychotic-related sexual dysfunction, including hyperprolactinemia, sedation, and antagonism of a number of neurotransmitter receptors (?-adrenergic, dopaminergic, histaminic, and muscarinic). Maintaining normal sexual function in people treated for mental disorders can affect their quality of life, mood, self-esteem, attitude toward taking medication, and compliance during therapy.

    Yawning is a familiar and phylogenetically widespread phenomenon, but no consensus exists regarding its functional significance. We tested the hypothesis that yawning communicates to others a transition from a state of physiological and/or psychological arousal (for example, due to action of a stressor) to a more relaxed state. This arousal reduction hypothesis predicts little yawning during arousal and more yawning (above baseline) during and after down-regulation of arousal. Experimental capture-restraint tests with wild adult Nazca boobies (Sula granti), a seabird, increased yawning frequency after release from restraint, but yawning was almost absent during tests. Natural maltreatment by non-parental adults also increased yawning by nestlings, but only after the maltreatment ended and the adult left. CORT (corticosterone) was a logical a priori element of the stress response affecting the stressor-yawning relationship under the arousal reduction hypothesis, and cannot be excluded as such for adults in capture-restraint tests but is apparently unimportant for nestlings being maltreated by adults. The arousal reduction hypothesis unites formerly disparate results on yawning: its socially contagious nature in some taxa, its clear pharmacological connection to the stress response, and its temporal linkage to transitions in arousal between consciousness and sleep.

    Sexual health in the menopause is a medical challenge because the progressive decline of sexual hormones interacts with the aging process and many psychosocial stressors modulate vulnerability for sexual symptoms (low sexual desire, poor arousal and lubrication, dyspareunia, orgasmic dysfunction and lack of satisfaction). In clinical practice, a coordinated approach is needed to optimally manage the risk for developing female sexual dysfunction (FSD), especially when chronic conditions are present. Biomedical and psychosocial interventions include general education, recognition of signs and symptoms, promotion of health, attention to the partner and individualization of treatment. Counselling to overcome personal and relational difficulties should be always combined with hormonal and non-hormonal strategies to maximize biological signals driving the sexual response. By enhancing women's abilities to cope with sexual changes at midlife, health care providers may significantly optimize healthy aging and partnership. PMID:24879777

    Placing a patient in a state of general anesthesia is crucial for safely and humanely performing most surgical and many nonsurgical procedures. How anesthetic drugs create the state of general anesthesia is considered a major mystery of modern medicine. Unconsciousness, induced by altered arousal and/or cognition, is perhaps the most fascinating behavioral state of general anesthesia. We perform a systems neuroscience analysis of the altered arousal states induced by five classes of intravenous anesthetics by relating their behavioral and physiological features to the molecular targets and neural circuits at which these drugs are purported to act. The altered states of arousal are sedation-unconsciousness, sedation-analgesia, dissociative anesthesia, pharmaco-logic non-REM sleep, and neuroleptic anesthesia. Each altered arousal state results from the anesthetic drugs acting at multiple targets in the central nervous system. Our analysis shows that general anesthesia is less mysterious than currently believed. PMID:21513454

    Collective rituals are present in all known societies, but their function is a matter of long-standing debates. Field observations suggest that they may enhance social cohesion and that their effects are not limited to those actively performing but affect the audience as well. Here we show physiological effects of synchronized arousal in a Spanish fire-walking ritual, between active participants and related spectators, but not participants and other members of the audience. We assessed arousal by heart rate dynamics and applied nonlinear mathematical analysis to heart rate data obtained from 38 participants. We compared synchronized arousal between fire-walkers and spectators. For this comparison, we used recurrence quantification analysis on individual data and cross-recurrence quantification analysis on pairs of participants' data. These methods identified fine-grained commonalities of arousal during the 30-min ritual between fire-walkers and related spectators but not unrelated spectators. This indicates that the mediating mechanism may be informational, because participants and related observers had very different bodily behavior. This study demonstrates that a collective ritual may evoke synchronized arousal over time between active participants and bystanders. It links field observations to a physiological basis and offers a unique approach for the quantification of social effects on human physiology during real-world interactions. PMID:21536887

  14. Contribution of Arousal from Sleep to Postevent Tachycardia in Patients with Obstructive Sleep Apnea

    2013-01-01

    Study Objectives: Heart rate increases after obstructive events in patients with obstructive sleep apnea (OSA). This response is generally attributed to arousal from sleep. Opening of the obstructed airway, however, is associated with ventilatory and hemodynamic changes that could result in physiologic responses unrelated to arousal. Our objective was to determine the contribution of these physiologic responses to postevent tachycardia. Design: Analysis of data obtained during previous research protocols. Setting: Academic sleep laboratory. Participants: Twenty patients with severe OSA. Interventions: Patients were placed on a continuous positive airway pressure (CPAP) device. CPAP was reduced during sleep to different levels (dial-downs), producing obstructive events of varying severity. Some dial-downs with severe obstruction were maintained until spontaneous airway opening. In others, CPAP was increased after three obstructed breaths, terminating the events approximately 10 sec before spontaneous termination in long dial-downs. Measurement and Results: Beat-by-beat heart rate (HR) was measured for 20 sec following airway opening. Spontaneous opening during sustained dial-downs occurred 21.9 ± 8.4 sec after dial-down, was associated with arousal, and resulted in the greatest postevent tachycardia (7.8 ± 4.0 min-1). However, deliberate termination of events (12.2 ± 2.6 sec after dial-down) was also followed by tachycardia that, in the absence of cortical arousal, showed a dose-response behavior, increasing with severity of obstruction and without apparent threshold. ?HR following deliberately brief, severe obstruction (3.8 ± 3.0 min-1) was approximately half the ?HR that followed spontaneous opening of equally severe obstructions despite the shorter duration and absence of cortical arousal. Conclusions: Postevent tachycardia is due in large part to physiologic (arousal-unrelated) responses that occur upon relief of obstruction.

    General arousal has been operationally defined as an enhanced motor activity and enhanced intensity of response to sensory stimuli. Even though the effects of gonadal hormones on mating behavior have been much studied, their potential effect on generalized arousal, as defined above, has never been evaluated. In the present study we employed a thoroughly validated assay of general arousal to determine the effects of estradiol (E) and testosterone (T) in gonadectomized female and male mice, respectively. The steroids were administered in three different ways: A fast-acting, water soluble preparation given intraperitoneally, an oil solution given subcutaneously, and an oil solution in a subcutaneous Silastic capsule. Motor activity and responses to sensory stimuli were recorded for 24h, 91h, and seven days following hormone administration, respectively. All measures of arousal varied according to the day/night cycle. The water soluble steroid preparation had no reliable effect. When the same doses of estradiol and testosterone were administered subcutaneously in an oil vehicle no effect of either treatment on arousal was observed. The subcutaneously implanted capsule containing estradiol or testosterone had a delayed effect on motor activity in females (four to seven days) but no effect in males. The long time required by the gonadal hormones for affecting arousal would be consistent with, but does not prove, a genomic action. The limited effects of E and T in our arousal assay suggest to us that the strongest actions of these hormones on arousal occur in the context of sequences of responses to sexually relevant stimuli.

    The physiological processes underlying trust are subject of intense interest in the behavioral sciences. However, very little is known about how trust modulates the affective link between individuals. We show here that trust has an effect on heart rate arousal and synchrony, a result consistent with research on joint action and experimental economics. We engaged participants in a series of joint action tasks which, for one group of participants, was interleaved with a PGG, and measured their heart synchrony and arousal. We found that the introduction of the economic game shifted participants' attention to the dynamics of the interaction. This was followed by increased arousal and synchrony of heart rate profiles. Also, the degree of heart rate synchrony was predictive of participants' expectations regarding their partners in the economic game. We conclude that the above changes in physiology and behavior are shaped by the valuation of other people's social behavior, and ultimately indicate trust building process. PMID:26037635

    The present study examined how well implicit measures were able to predict sexual orientation. Most previous research in the sexual orientation domain has been dependent upon self-report, which requires explicit, conscious awareness of sexual orientation and/or erotic preferences. On the other hand, implicit measurements are thought to be able to reflect immediate automatic reactions that may not be available to introspection. A total of 50 heterosexual and 25 homosexual men completed two implicit measures: the Implicit Association Task (IAT) and the Priming Task (PT). Sexual orientation was determined by self-report. In the PT, participants classified words as either sexually attractive or unattractive. Each word was preceded by a "prime" that was a picture of either a male or a female. The IAT consisted of classifying these same words as sexually attractive or unattractive, and classifying the pictures as either male or female. Both the IAT and the PT had very good ability to predict sexual orientation with Area Under the Curves (AUC) of 0.97 and 0.86, respectively. Unlike many other reports of implicit measures of behavior, the IAT and the PT correlated strongly with each other, and also with the explicit measurements of sexual orientation. It was concluded that these implicit measures can provide a valuable tool for research into sexual orientation and erotic preference that can complement existing measures, such as self-report questionnaires and physiological changes in sexual arousal in response to erotic stimuli.

    Electroencephalography (EEG) often fails to assess both the level (i.e., arousal) and the content (i.e., awareness) of pathologically altered consciousness in patients without motor responsiveness. This might be related to a decline of awareness, to episodes of low arousal and disturbed sleep patterns, and/or to distorting and attenuating effects of the skull and intermediate tissue on the recorded brain signals. Novel approaches are required to overcome these limitations. We introduced epidural electrocorticography (ECoG) for monitoring of cortical physiology in a late-stage amytrophic lateral sclerosis patient in completely locked-in state (CLIS). Despite long-term application for a period of six months, no implant-related complications occurred. Recordings from the left frontal cortex were sufficient to identify three arousal states. Spectral analysis of the intrinsic oscillatory activity enabled us to extract state-dependent dominant frequencies at <4, ~7 and ~20 Hz, representing sleep-like periods, and phases of low and elevated arousal, respectively. In the absence of other biomarkers, ECoG proved to be a reliable tool for monitoring circadian rhythmicity, i.e., avoiding interference with the patient when he was sleeping and exploiting time windows of responsiveness. Moreover, the effects of interventions addressing the patient's arousal, e.g., amantadine medication, could be evaluated objectively on the basis of physiological markers, even in the absence of behavioral parameters. Epidural ECoG constitutes a feasible trade-off between surgical risk and quality of recorded brain signals to gain information on the patient's present level of arousal. This approach enables us to optimize the timing of interactions and medical interventions, all of which should take place when the patient is in a phase of high arousal. Furthermore, avoiding low-responsiveness periods will facilitate measures to implement alternative communication pathways involving brain-computer interfaces (BCI). PMID:25374532

    A false feedback paradigm was used to produce a discrepancy between expected and "actual" tumescence among 57 sexually dysfunctional and 58 sexually functional men randomly assigned to one of four false tumescence feedback conditions: negative (NEG), neutral (NEU), positive (POS), or no (NO) feedback. Participants predicted an erection score before viewing an erotic film and then received false tumescence feedback based on this score. Tumescence and cognitive ratings were obtained before and after the feedback. It was predicted that discrepancies would differ between dysfunctional and functional participants such that functional participants would have the ability to overcome discrepancies, whereas dysfunctional participants would not. As expected, POS decreased tumescence for dysfunctional participants and NO did not influence tumescence for either group. Unexpectedly, NEU decreased tumescence for dysfunctional participants and NEG decreased tumescence for functional participants. Despite tumescence changes, cognitive ratings generally followed the feedback that was given. These results only partially support current models of sexual dysfunction and behavioral regulation. Anxiety, self-focused attention, cognitive interference, and unexpectedness of the feedback could not account for the partial support. However, most feedback that was outside of the realm of the status quo for both functional and dysfunctional participants did decrease tumescence, despite outcome expectancies. These results suggest that both functional and dysfunctional men may be at risk for erectile failure should feedback about their performance be discrepant from what they expect. Prevention and treatment should focus on preparing men for occasional erectile failure and on helping them overcome discrepant feedback. PMID:18561016

    Background: The scar tissue formed by episiotomy during vaginal delivery, and the related pain, is very frequent. The change in the normal anatomy can cause cosmetic and physiologic problems. It can affect and cause deterioration in sexual functions. Therefore, making the right diagnosis and applying the right surgical procedures are very important. Aims: Our aim was to examine the effect of the perineoplasty operation on the sexual dysfunctions that present due to vaginal delivery. Study Design: Self-controlled study. Methods: Forty patients, who attended our clinic between April 2012 and May 2013, and who were between the ages of 20 and 50 years, were included in the study. The patients had complaints of scar tissue in the perineum and various sexual dysfunctions after vaginal delivery, and they were suitable for perineoplasty. The Female Sexual Function Index (FSFI) questionnaire was applied to the patients before and 6 months after the operation, and the results were compared. Results: After the perineoplasty operation, there was a statistically significant improvement in the patients in the domains of sexual desire, arousal, lubrication, orgasm, and sexual satisfaction (p<0.005). However, there was no significant improvement in the feeling of pain during sexual intercourse (p=0.184). The mean±SD total FSFI score increased significantly after the operation (p<0.005). Conclusion: The sexual dysfunctions that develop due to perineal damage during vaginal delivery can benefit significantly from the perineoplasty operation if the indications are correct. However, vaginal perineoplasty did not provide an improvement in dyspareunia. PMID:26185713

    The study of arousal and attention could be of prominent importance for elucidating both fundamental and practical aspects of the mind-brain puzzle. Defined as "general activation of mind" (Kahnemann in Attention and effort. Prentice-Hall, New Jersey, 1973), or "general operation of consciousness" (Thacher and John in Functional neuroscience: foundations of cognitive processing. Erlbaum, Hillsdale, 1977), arousal can be considered as a starting point of fundamental research on consciousness. Similar role could be assigned to attention, which can be defined by substituting the attributes "general" with "focused". Concerning the practical applications, the empirically established correlation between neuronal oscillations and arousal/attention levels is widely used in research and clinics, including neurofeedback, brain-computer communication, etc. However, the neurophysical mechanism underlying this correlation is still not clear enough. In this paper, after reviewing some present classical and quantum approaches, a transition probability concept of arousal based on field-dipole quantum interactions and information entropy is elaborated. The obtained analytical expressions and numerical values correspond to classical empirical results for arousal and attention, including the characteristic frequency dependence and intervals. Simultaneously, the fundamental (substrate) role of EEG spectrum has been enlightened, whereby the attention appears to be a bridge between arousal and the content of consciousness. Finally, some clinical implications, including the brain-rate parameter as an indicator of arousal and attention levels, are provided. PMID:18975019

    Animals modulate their arousal state to ensure that their sensory responsiveness and locomotor activity match environmental demands. Neuropeptides can regulate arousal, but studies of their roles in vertebrates have been constrained by the vast array of neuropeptides and their pleiotropic effects. To overcome these limitations, we systematically dissected the neuropeptidergic modulation of arousal in larval zebrafish. We quantified spontaneous locomotor activity and responsiveness to sensory stimuli after genetically induced expression of seven evolutionarily conserved neuropeptides, including adenylate cyclase activating polypeptide 1b (adcyap1b), cocaine-related and amphetamine-related transcript (cart), cholecystokinin (cck), calcitonin gene-related peptide (cgrp), galanin, hypocretin, and nociceptin. Our study reveals that arousal behaviors are dissociable: neuropeptide expression uncoupled spontaneous activity from sensory responsiveness, and uncovered modality-specific effects upon sensory responsiveness. Principal components analysis and phenotypic clustering revealed both shared and divergent features of neuropeptidergic functions: hypocretin and cgrp stimulated spontaneous locomotor activity, whereas galanin and nociceptin attenuated these behaviors. In contrast, cart and adcyap1b enhanced sensory responsiveness yet had minimal impacts on spontaneous activity, and cck expression induced the opposite effects. Furthermore, hypocretin and nociceptin induced modality-specific differences in responsiveness to changes in illumination. Our study provides the first systematic and high-throughput analysis of neuropeptidergic modulation of arousal, demonstrates that arousal can be partitioned into independent behavioral components, and reveals novel and conserved functions of neuropeptides in regulating arousal.

    From a classical viewpoint, sex-specific behavior and physiological functions as well as the brain structures of mammals such as rats and mice, have been thought to be influenced by perinatal sex steroids secreted by the gonads. Sex steroids have also been thought to affect the differentiation of the sex-typical behavior of a few members of the avian order Galliformes, including the Japanese quail and chickens, during their development in ovo. However, recent mammalian studies that focused on the artificial shuffling or knockout of the sex-determining gene, Sry, have revealed that sex chromosomal effects may be associated with particular types of sex-linked differences such as aggression levels, social interaction, and autoimmune diseases, independently of sex steroid-mediated effects. In addition, studies on naturally occurring, rare phenomena such as gynandromorphic birds and experimentally constructed chimeras in which the composition of sex chromosomes in the brain differs from that in the other parts of the body, indicated that sex chromosomes play certain direct roles in the sex-specific differentiation of the gonads and the brain. In this article, we review the relative contributions of sex steroids and sex chromosomes in the determination of brain functions related to sexual behavior and reproductive physiology in mammals and birds.

    The European eel migrates 5,000–6,000 km to the Sargasso Sea to reproduce. Because they venture into the ocean in a pre-pubertal state and reproduce after swimming for months, a strong interaction between swimming and sexual maturation is expected. Many swimming trials have been performed in 22 swim tunnels to elucidate their performance and the impact on maturation. European eels are able to swim long distances at a cost of 10–12 mg fat/km which is 4–6 times more efficient than salmonids. The total energy costs of reproduction correspond to 67% of the fat stores. During long distance swimming, the body composition stays the same showing that energy consumption calculations cannot be based on fat alone but need to be compensated for protein oxidation. The optimal swimming speed is 0.61–0.67 m s?1, which is ~60% higher than the generally assumed cruise speed of 0.4 m s?1 and implies that female eels may reach the Sargasso Sea within 3.5 months instead of the assumed 6 months. Swimming trials showed lipid deposition and oocyte growth, which are the first steps of sexual maturation. To investigate effects of oceanic migration on maturation, we simulated group-wise migration in a large swim-gutter with seawater. These trials showed suppressed gonadotropin expression and vitellogenesis in females, while in contrast continued sexual maturation was observed in silver males. The induction of lipid deposition in the oocytes and the inhibition of vitellogenesis by swimming in females suggest a natural sequence of events quite different from artificial maturation protocols.

    Models of suicidal behavior that assess the interplay of multiple risk factors are needed to better identify at-risk individuals during periods of elevated risk, including following psychiatric hospitalization. This study investigated contributions of facets of anger, gender, and sexual victimization to risk for suicide attempts after hospital discharge. Psychiatric patients (N = 748; ages 18-40; 44% female) recruited from 3 inpatient facilities were assessed during hospitalization and every 10 weeks during the year following discharge as part of the MacArthur Violence Risk Assessment Study. Multiple logistic regression models with facets of anger (disposition toward physiological arousal, hostile cognitions, and angry behavior) from the Novaco Anger Scale (Novaco, 1994), gender, and childhood sexual victimization history were used to predict suicide attempts in the year following hospital discharge. Facets of anger differentially predicted suicide attempts as a function of gender and sexual victimization history, over and above the variance accounted for by symptoms of depression, anxiety, and recent suicide attempts. In men, greater disposition toward angry behavior predicted an overall greater likelihood of a suicide attempt in the year following hospital discharge, particularly among men with childhood sexual victimization. In women with a history of childhood sexual victimization, physiological arousal predicted suicide attempts. Results indicate that facets of anger are relevant predictors of suicide attempts following hospital discharge for psychiatric patients with a history of childhood sexual victimization. Further, results suggest that incorporating gender and victimization history into models of risk for suicide can help clarify relationships between anger and self-directed violence. PMID:23834063

  4. Vocal correlates of sender-identity and arousal in the isolation calls of domestic kitten (Felis silvestris catus)

    2012-01-01

    Introduction Human speech does not only communicate linguistic information but also paralinguistic features, e.g. information about the identity and the arousal state of the sender. Comparable morphological and physiological constraints on vocal production in mammals suggest the existence of commonalities encoding sender-identity and the arousal state of a sender across mammals. To explore this hypothesis and to investigate whether specific acoustic parameters encode for sender-identity while others encode for arousal, we studied infants of the domestic cat (Felis silvestris catus). Kittens are an excellent model for analysing vocal correlates of sender-identity and arousal. They strongly depend on the care of their mother. Thus, the acoustical conveyance of sender-identity and arousal may be important for their survival. Results We recorded calls of 18 kittens in an experimentally-induced separation paradigm, where kittens were spatially separated from their mother and siblings. In the Low arousal condition, infants were just separated without any manipulation. In the High arousal condition infants were handled by the experimenter. Multi-parametric sound analyses revealed that kitten isolation calls are individually distinct and differ between the Low and High arousal conditions. Our results suggested that source- and filter-related parameters are important for encoding sender-identity, whereas time-, source- and tonality-related parameters are important for encoding arousal. Conclusion Comparable findings in other mammalian lineages provide evidence for commonalities in non-verbal cues encoding sender-identity and arousal across mammals comparable to paralinguistic cues in humans. This favours the establishment of general concepts for voice recognition and emotions in humans and animals. PMID:23259698

    Study Objectives: The present study aimed at further investigating trait aspects of sleep-related cognitive arousal and general cognitive arousal and their association with both objective and subjective sleep parameters in primary insomnia patients. Methods: A clinical sample of 182 primary insomnia patients and 54 healthy controls was investigated using 2 nights of polysomnography, subjective sleep variables, and a questionnaire on sleep-related and general cognitive arousal. Results: Compared to healthy controls, primary insomnia patients showed both more sleep-related and general cognitive arousal. Furthermore, sleep-related cognitive arousal was closely associated with measures of sleep-onset and sleep-maintenance problems, while general cognitive arousal was not. Conclusions: Cognitive-behavioral treatment for insomnia might benefit from dedicating more effort to psychological interventions that are able to reduce sleep-related cognitive arousal.

    Older adults have been shown to describe their happiness as lower in arousal when compared to younger adults. In addition, older adults prefer low arousal positive emotions over high arousal positive emotions in their daily lives. We experimentally investigated whether or not changing a few words in the description of happiness could influence a person’s rating of their happiness. We randomly assigned 193 participants, aged 22–92 years, to one of three conditions (high arousal, low arousal, or control). In line with previous findings, we found that older participants rated their happiness lower when framed as high in arousal (i.e., ecstatic, to be bursting with positive emotions) and rated their happiness higher when framed as low in arousal (i.e., satisfied, to have a life filled with positive emotions). Younger adults remained uninfluenced by the manipulation. Our study demonstrates that arousal is essential to understanding ratings of happiness, and gives support to the notion that there are age differences in the preference for arousal.

    Orphanin FQ/nociceptin (OFQ/N) inhibits the activity of proopiomelanocortin (POMC) neurones located in the hypothalamic arcuate nucleus (ARH) that regulate female sexual behaviour and energy balance. We tested the hypothesis that gonadal steroids differentially modulate the ability of OFQ/N to inhibit these cells via presynaptic inhibition of transmitter release and postsynaptic activation of G protein-gated, inwardly-rectifying K+ (GIRK)-1 channels. Whole-cell patch clamp recordings were performed in hypothalamic slices prepared from ovariectomised rats. OFQ/N (1 ?M) decreased the frequency of miniature excitatory postsynaptic currents (mEPSCs) and inhibitory postsynaptic currents (mIPSCs), and also caused a robust outward current in the presence of tetrodotoxin, in ARH neurones from vehicle- treated animals. A priming dose of oestradiol benzoate (EB; 2 ?g) increased basal mEPSC frequency, markedly diminished both the OFQ/N-induced decrease in mEPSC frequency and the activation of GIRK-1 currents, and potentiated the OFQ/N-induced decrease in mIPSC frequency. Steroid treatment regimens that facilitate sexual receptivity reinstate the basal mEPSC frequency, the OFQ/N-induced decrease in mEPSC frequency and the activation of GIRK-1 currents to levels observed in vehicle-treated controls, and largely abolish the ability of OFQ/N to decrease mIPSC frequency. These effects were observed in an appreciable population of identified POMC neurones, nearly one-half of which projected to the medial preoptic nucleus. Taken together, these data reveal that gonadal steroids influence the pleiotropic actions of OFQ/N on ARH neurones, including POMC neurones, in a disparate manner. These temporal changes in OFQ/N responsiveness further implicate this neuropeptide system as a critical mediator of the gonadal steroid regulation of reproductive behaviour. PMID:24617903

    The redefinition of posttraumatic stress disorder (PTSD) in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, has highlighted a range of posttraumatic affects beyond fear and anxiety. For survivors of interpersonal violence, shame has been shown to be an important contributor of self-reported symptomatology. Although biological models of PTSD emphasize physiological arousal secondary to fear and anxiety, evidence suggests that shame might be related to increased arousal as well. This study tested the contributions of anxiety, fear, and shame to autonomic arousal in a sample of female victims (N = 27) of interpersonal violence with PTSD. Shame proneness was the only significant correlate of autonomic arousal during a trauma reminder paradigm. These findings indicate that shame corresponds to important indicators of changes to the autonomic nervous system that have previously been assumed to be fear related. PMID:25894989

    Studying vocal correlates of emotions is important to provide a better understanding of the evolution of emotion expression through cross-species comparisons. Emotions are composed of two main dimensions: emotional arousal (calm versus excited) and valence (negative versus positive). These two dimensions could be encoded in different vocal parameters (segregation of information) or in the same parameters, inducing a trade-off between cues indicating emotional arousal and valence. We investigated these two hypotheses in horses. We placed horses in five situations eliciting several arousal levels and positive as well as negative valence. Physiological and behavioral measures collected during the tests suggested the presence of different underlying emotions. First, using detailed vocal analyses, we discovered that all whinnies contained two fundamental frequencies (“F0” and “G0”), which were not harmonically related, suggesting biphonation. Second, we found that F0 and the energy spectrum encoded arousal, while G0 and whinny duration encoded valence. Our results show that cues to emotional arousal and valence are segregated in different, relatively independent parameters of horse whinnies. Most of the emotion-related changes to vocalizations that we observed are similar to those observed in humans and other species, suggesting that vocal expression of emotions has been conserved throughout evolution.

    2012-02-01

    Distractions from sexual cues have been shown to decrease the sexual response, but it is unclear how distracters decrease sexual response. Individual differences may modulate the efficacy of distracters. Forty women viewed three sexual films while their labial temperature and continuous self-reported sexual arousal were monitored. One sexual film had simultaneous verbal distracters concerning dissatisfaction with one's physical appearance (higher salience distracter), a second had distracters concerning daily chores (lower salience distracter), and the third sexual film had no distracters. Participant's reporting greater relationship satisfaction and more communication with their partner about their own physical appearance were expected to decrease the efficacy (increased sexual arousal) of the distracters concerning physical appearance. Contrary to expectations, women who received less feedback about their body from their partners reported less sexual arousal during a sexual film with body distracters than a sexual film with general distracters or a sexual film with no distracters. All women exhibited lower labial temperature in Minutes 2 and 3 of the sexual film with body image distracters as compared to the other two sexual films. Possible explanations explored include self-verification theory and individual differences in the indicators that women consider when rating their sexual arousal. PMID:22083654

    2005-01-01

    ACCEPTANCE OF AN EVIDENCE-BASED CONCEPTUALIZATION OF WOMEN'S SEXUAL RESPONSE combining interpersonal, contextual, personal psychological and biological factors has led to recently published recommendations for revision of definitions of women's sexual disorders found in the American Psychiatric Association's Diagnostic and Statistical Manual (DSM–IV-TR). DSM-IV definitions have focused on absence of sexual fantasies and sexual desire prior to sexual activity and arousal, even though the frequency of this type of desire is known to vary greatly among women without sexual complaints. DSM-IV definitions also focus on genital swelling and lubrication, entities known to correlate poorly with subjective sexual arousal and pleasure. The revised definitions consider the many reasons women agree to or instigate sexual activity, and reflect the importance of subjective sexual arousal. The underlying conceptualization of a circular sex-response cycle of overlapping phases in a variable order may facilitate not only the assessment but also the management of dysfunction, the principles of which are briefly recounted.

    Recent work has questioned whether the negativity bias is a distinct component of affective picture processing. The current study was designed to determine whether there are different neural correlates of processing positive and negative pictures using event-related brain potentials. The early posterior negativity and late positive potential were greatest in amplitude for erotic pictures. Partial Least Squares analysis revealed one latent variable that distinguished erotic pictures from neutral and positive pictures and another that differentiated negative pictures from neutral and positive pictures. The effects of orienting task on the neural correlates of processing negative and erotic pictures indicate that affective picture processing is sensitive to both stimulus-driven, and attentional or decision processes. The current data, together with other recent findings from our laboratory, lead to the suggestion that there are distinct neural correlates of processing negative and positive stimuli during affective picture processing.

    By 2022, the number of survivors is expected to grow to nearly 18 million. Therefore, addressing acute and chronic negative sequelae of a cancer diagnosis and its treatments becomes a health imperative. For women with a history of breast cancer, one of the common goals of treatment and prevention of recurrence is to reduce circulating concentrations of estradiol, especially in women with hormone receptor positive breast cancer. Hormone deprivation after a diagnosis of breast cancer impacts physiological targets other than in the breast tissue and can result in unwanted side effects, all of which can negatively impact quality of life and function and cause distress. Symptoms that are most strongly linked by evidence to hormone changes after cancer diagnosis and treatment include hot flashes, night sweats, sleep changes, fatigue, mood changes, and diminishing sexual function, including vaginal atrophy (decreased arousal, dryness and dyspareunia), infertility, decreased desire and negative self-image. Weight gain and resulting body image changes are often concomitants of the abrupt onset of treatment-induced menopause.The purpose of this chapter is to briefly review what is known about the advent of premature menopause in women treated for breast cancer, menopausal symptoms that are exacerbated by endocrine treatments for breast cancer, and the associated concerns of hot flashes and related menopausal symptoms, sexual health and fertility issues. We will discuss limitations in the current research and propose strategies that address current limitations in order to move the science forward. PMID:26059933

    Persistent Genital Arousal Disorder (PGAD) refers to the experience of persistent sensations of genital arousal that are felt to be unprovoked, intrusive and unrelieved by one or several orgasms. It is often mistaken for hypersexuality since PGAD often results in a high frequency of sexual behaviour. At present little is known with certainty about the etiology of this condition. We described a woman with typical PGAD symptoms and orgasmic seizures that we found to be related to a specific epileptic focus. We performed a EEG/MEG and fMRI spontaneous activity study during genital arousal symptoms and after the chronic administration of 300 mg/day of topiramate. From MEG data an epileptic focus was localized in the left posterior insular gyrus (LPIG). FMRI data evidenced that sexual excitation symptoms with PGAD could be correlated with an increased functional connectivity (FC) between different brain areas: LPIG (epileptic focus), left middle frontal gyrus, left inferior and superior temporal gyrus and left inferior parietal lobe. The reduction of the FC observed after antiepileptic therapy was more marked in the left than in the right hemisphere in agreement with the lateralization identified by MEG results. Treatment completely abolished PGAD symptoms and functional hyperconnectivity. The functional hyperconnectivity found in the neuronal network including the epileptic focus could suggest a possible central mechanism for PGAD. PMID:20144694

However, it is not clear from previous work whether arousing stimuli impair memory for all non-arousing nearby information or just background information. In several experiments, we tested how emotionally arousing pictures affect memory for nearby pictures and for background information. We found that when two pictures were presented together, having one of the pictures be arousing did not affect item and location memory for the other picture. In contrast, an arousing picture impaired memory for a background pattern. These findings suggest that arousal impairs memory for information that is the target of perceptual suppression, such as background information when there is a figure-ground distinction, but does not impair memory for other foreground information.

    The current study examined the differences in arousal (physiologically and subjectively) between gamblers and non-gamblers. Thirty students from a mid-sized university took part in the study for a chance to win money in a gambling task. Nearly half of the participants identified themselves as non-gamblers and slightly more than half of the participants considered themselves gamblers. Findings indicated that gamblers experienced a significantly higher increase in physiological arousal (heart rate) compared to non-gamblers during the gambling experience. The results suggests the possibility that physiological arousal may play a role in the appeal of gambling to certain types of people. Furthermore, when gamblers suffered a loss at the end of the game, they reported feeling worse as compared to the non-gamblers and relative to their state before playing. Moreover, this affective change explained 28.6% of the variance in gambling behavior according to self-reports. Findings suggest that gamblers in our study may have been more personally invested in the gambling tasks, such that losing was more disappointing to the habitual gamblers than the non-gamblers.

    We investigated the impact of sexual stimuli and the influence of sexual motivation on the performance in a dot-probe task and a line-orientation task in a large sample of males and females. All pictures (neutral, erotic) were rated on the dimensions of valence, arousal, disgust, and sexual arousal. Additionally, questionnaires measuring sexual interest/desire/motivation were employed. The ratings of the sexual stimuli point to a successful picture selection because sexual arousal did not differ between the sexes. The stimuli were equally arousing for men and women. Higher scores in the employed questionnaires measuring sexual interest/desire/motivation led to higher sexual arousal ratings of the sex pictures. Attentional bias towards sex pictures was observed in both experimental tasks. The attentional biases measured by the dot-probe and the line-orientation task were moderately intercorrelated suggesting attentional bias as a possible marker for a sex-attention trait. Finally, only the sexual sensation seeking score correlated with the attentional biases of the two tasks. Future research is needed to increase the predictive power of these indirect measures of sexual interest. PMID:25238545

    Studies of contagious yawning have reported inconsistent findings regarding whether dogs exhibit this behavior and whether it is mediated by social-cognitive processes or the result of physiological arousal. We investigated why some dogs yawn in response to human yawns; particularly, whether these dogs are exceptional in their ability to understand human social cues or whether they were more physiologically aroused. Sixty shelter dogs were exposed to yawning and nonyawning control stimuli demonstrated by an unfamiliar human. We took salivary cortisol samples before and after testing to determine the role of arousal in yawn contagion. Dogs were tested on the object-choice task to assess their sensitivity for interpreting human social cues. We found that 12 dogs yawned only in response to human yawns (i.e., appeared to exhibit yawn contagion), though contagious yawning at the population level was not observed. Dogs that exhibited yawn contagion did not perform better on the object-choice task than other dogs, but their cortisol levels remained elevated after exposure to human yawning, whereas other dogs had reduced cortisol levels following yawning stimuli relative to their baseline levels. We interpret these findings as showing that human yawning, when presented in a stressful context, can further influence arousal in dogs, which then causes some to yawn. Although the precise social-cognitive mechanisms that underlie contagious yawning in dogs are still unclear, yawning between humans and dogs may involve some communicative function that is modulated by context and arousal.

    2014-01-01

    Sexuality is a complex aspect of the human being’s life and is more than just the sexual act. Normal sexual functioning consists of sexual activity with transition through the phases from arousal to relaxation with no problems, and with a feeling of pleasure, fulfillment and satisfaction. Rheumatic diseases may affect all aspects of life including sexual functioning. The reasons for disturbing sexual functioning are multifactorial and comprise disease-related factors as well as therapy. Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease characterized by progressive joint destruction resulting from chronic synovial inflammation. It leads to various degrees of disability, and ultimately has a profound impact on the social, economic, psychological, and sexual aspects of the patient’s life. This is a systemic review about the impact of RA on sexual functioning. PMID:24829873

    Cultural effects on sexuality are pervasive and potentially of great clinical importance, but have not yet received sustained empirical attention. The purpose of this study was to explore the role of acculturation on sexual permissiveness and sexual function, with a particular focus on arousal in Asian women living in Canada. We also compared questionnaire responses between Asian and Euro-Canadian groups in hopes of investigating whether acculturation captured unique information not predicted by ethnic group affiliation. Euro-Canadian (n = 173) and Asian (n = 176) female university students completed a battery of questionnaires in private. Euro-Canadian women had significantly more sexual knowledge and experiences, more liberal attitudes, and higher rates of desire, arousal, sexual receptivity, and sexual pleasure. Anxiety from anticipated sexual activity was significantly higher in Asian women, but the groups did not differ significantly on relationship satisfaction or problems with sexual function. Acculturation to Western culture, as well as maintained affiliation with traditional Asian heritage, were both significantly and independently related to sexual attitudes above and beyond length of residency in Canada, and beyond ethnic group comparisons. Overall, these data suggest that measurement of acculturation may capture information about an individual's unique acculturation pattern that is not evident when focusing solely on ethnic group comparisons or length of residency, and that such findings may be important in facilitating the assessment, classification, and treatment of sexual difficulties in Asian women.

    Introduction Time spent viewing visual sexual stimuli (VSS) has the potential to habituate the sexual response and generalize to the partner context. Aim The aim of this study was to examine whether the time spent viewing VSS is related to sexual responsiveness felt in the laboratory or with a sexual partner. Methods Nontreatment-seeking men (N?=?280) reported their weekly average VSS viewing in hours. VSS hours were examined in relation to the sexual arousal experienced while viewing a standardized sexual film in the laboratory and erectile problems experienced with a sexual partner. Main Outcome Measures Self-reported sexual arousal in response to sexual films and erectile problems on the International Index of Erectile Function were the main outcome measures. Results More hours viewing VSS was related to stronger experienced sexual responses to VSS in the laboratory, was unrelated to erectile functioning with a partner, and was related to stronger desire for sex with a partner. Conclusions VSS use within the range of hours tested is unlikely to negatively impact sexual functioning, given that responses actually were stronger in those who viewed more VSS. PMID:26185674

    Objective To assess the degree to which a history of CSA moderates the association between sexual functioning and sexual distress in women. Method Women with (n = 105, M age = 33.71, 66.1% Caucasian) and without (n = 71, M age = 32.63, 74.7% Caucasian) a history of CSA taking part in a larger clinical trial completed self-report questionnaires at intake including the Sexual Satisfaction Scale for Women (SSS-W), the Female Sexual Function Index (FSFI), and the Trauma History Questionnaire (THQ). Results Desire, arousal, lubrication, and orgasm interacted with sexual abuse status in predicting sexual distress such that sexual functioning was more weakly associated with distress for women with a history of CSA. This disconnect was more pronounced for women who were abused by a family member. Conclusion CSA status serves as an important moderator of the association between sexual functioning and sexual distress in women. Specifically, women with a history of CSA show higher levels of distress in the context of good sexual functioning as compared to women without a history of CSA. Possible explanations and clinical implications are discussed. PMID:22391416

    Children with autism spectrum disorder (ASD) experience high rates of social stress and anxious arousal. Preliminary evidence suggests that companion animals can act as buffers against the adverse effects of social stress in adults. We measured continuous physiological arousal in children with ASD and typically developing (TD) children in a social context during four conditions: (a) a baseline of reading silently, (b) a scripted classroom activity involving reading aloud, (c) free play with peers and toys, and (d) free play with peers and animals (guinea pigs). Our results confirmed heightened arousal among children with ASD compared to TD children in all conditions, except when the animals were present. Children with ASD showed a 43% decrease in skin conductance responses during free play with peers in the presence of animals, compared to toys. Thus, animals may act as social buffers for children with ASD, conferring unique anxiolytic effects. © 2015 Wiley Periodicals, Inc. Dev Psychobiol 57: 584-595, 2015. PMID:25913902

    Locusts have two large collision-detecting neurons, the descending contralateral movement detectors (DCMDs) that signal object approach and trigger evasive glides during flight. We sought to investigate whether vision for action, when the locust is in an aroused state rather than a passive viewer, significantly alters visual processing in this collision-detecting pathway. To do this we used two different approaches to determine how the arousal state of a locust affects the prolonged periods of high-frequency spikes typical of the DCMD response to approaching objects that trigger evasive glides. First, we manipulated arousal state in the locust by applying a brief mechanical stimulation to the hind leg; this type of change of state occurs when gregarious locusts accumulate in high-density swarms. Second, we examined DCMD responses during flight because flight produces a heightened physiological state of arousal in locusts. When arousal was induced by either method we found that the DCMD response recovered from a previously habituated state; that it followed object motion throughout approach; and--most important--that it was significantly more likely to generate the maintained spike frequencies capable of evoking gliding dives even with extremely short intervals (1.8 s) between approaches. Overall, tethered flying locusts responded to 41% of simulated approaching objects (sets of 6 with 1.8 s ISI). When we injected epinastine, the neuronal octopamine receptor antagonist, into the hemolymph responsiveness declined to 12%, suggesting that octopamine plays a significant role in maintaining responsiveness of the DCMD and the locust to visual stimuli during flight.

    Introduction The American Psychiatric Association recommends considering sexually related personal distress when assessing female sexual dysfunction. Currently, there is little data regarding the impact of sexual complaints on sexual distress. Aim To investigate the association between sexual complaints and perceived sexual distress in a population of ambulatory adult women. Methods Using the short forms of the Personal Experiences Questionnaire and Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire, we assessed sexual complaints among 305 women seeking outpatient gynecologic care. Depressive symptoms were quantified using the Center for Epidemiologic Studies Depression (CESD) score. Sexual distress was measured using the Female Sexual Distress Scale (FSDS). Using multivariable logistic regression, we compared sexual complaints between distressed and nondistressed women. Main Outcome Measures Sexual distress, defined by FSDS score ?15. Results FSDS scores were available for 292/305 participants. Seventy-six (26%) scores reflected distress. Distressed women were more likely to be younger (55.2 ± 1.0 years vs. 56.7 ± 0.8 years, P = 0.017); have higher CESD scores (16.6 vs. 9.5, P = 0.001); and report decreased arousal (56.8% vs. 25.1%, P = 0.001), infrequent orgasm (54% vs. 28.8%, P = 0.001), and dyspareunia (39.7% vs. 10.6%, P = 0.001). Women with sexual distress were also more likely to report sexual difficulty related to pelvic floor symptoms, including urinary incontinence with sexual activity (9% vs. 1.3%, P = 0.005), sexual avoidance due to vaginal prolapse (13.9% vs. 1%, P = 0.001), or sexual activity restriction due to fear of urinary incontinence (14.9% vs. 0.5%, P = 0.001). After multivariate analysis, sexual distress was significantly associated with dyspareunia (odds ratio [OR] 3.11, P = 0.008) and depression score (OR 1.05, P = 0.006), and inversely associated with feelings of arousal during sex (OR 0.19, P = 0.001). Conclusion Our results indicate that sexually related personal distress is significantly associated with dyspareunia, depressive symptoms, and decreased arousal during sexual activity. This contributes to our understanding of how sexual complaints may adversely affect women’s quality of life. PMID:20704643

    2011-01-01

    Despite the World Health Organization's definition of sexual health as a state of well-being, virtually no public health research has examined sexual well-being outcomes, including sexual satisfaction. Emerging evidence suggests that sexual well-being indicators are associated with more classic measures of healthy sexual behaviors. We surveyed 2168 university students in the United States and asked them to rate their physiological and psychological satisfaction with their current sexual lives. Many respondents reported that they were either satisfied (approximately half) or very satisfied (approximately one third). In multivariate analyses, significant (P < .05) correlates of both physiological and psychological satisfaction included sexual guilt, sexual self-comfort, self-esteem (especially among men), relationship status, and sexual frequency. To enhance sexual well-being, public health practitioners should work to improve sexual self-comfort, alleviate sexual guilt, and promote longer term relationships. PMID:21778509

    1980-01-01

    A literature review was conducted to assess the basis of and techniques for physiological assessment of mental workload. The study findings reviewed had shortcomings involving one or more of the following basic problems: (1) physiologic arousal can be easily driven by nonworkload factors, confounding any proposed metric; (2) the profound absence of underlying physiologic models has promulgated a multiplicity of seemingly arbitrary signal processing techniques; (3) the unspecified multidimensional nature of physiological "state" has given rise to a broad spectrum of competing noncommensurate metrics; and (4) the lack of an adequate definition of workload compels physiologic correlations to suffer either from the vagueness of implicit workload measures or from the variance of explicit subjective assessments. Using specific studies as examples, two basic signal processing/data reduction techniques in current use, time and ensemble averaging are discussed.

    The incidence of sudden infant death syndrome (SIDS) has dropped significantly in most countries following the development of education campaigns on the avoidance of risk factors for SIDS. However, questions have been raised about the physiological mechanism responsible for the effects of these environmental risk factors. Since 1985, a series of prospective, multicentric studies have been developed to address these questions; over 20,000 infants were recorded during one night in a sleep laboratory and among these, 40 infants eventually died of SIDS. In this review, the following methods were employed: sleep recordings and analysis, monitoring procedure, data analysis of sleep stages, cardiorespiratory and oxygen saturation, scoring of arousals, spectral analysis of the heart rate and the determination of arousal thresholds, and statistical analysis and the results including sleep apneas, arousals and heart rate and autonomic controls in both future SIDS victims and normal infants were introduced separately. In addition, the physiological effect of prenatal risk factors (maternal smoking during gestation) and postnatal risk factors (administration of sedative drugs, prone sleeping position, ambient temperature, sleeping with the face covered by a bed sheet, pacifiers and breastfeeding) in normal infants were analyzed. In conclusion, the physiological studies undertaken on the basis of epidemiological findings provide some clues about the physiological mechanisms linked with SIDS. Although the description of the mechanisms responsible for SIDS is still far from complete, it appears to involve both arousal responses and cardiac autonomic controls during sleep-wake processes.

    2008-01-01

    The influence of cognitive and emotional variables on specific female sexual dysfunctions was investigated. A total of 207 women (160 without sexual problems and 47 with a Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) diagnosis of sexual dysfunction) answered a set of questionnaires assessing cognitive and emotional variables (cognitive schemas activated in sexual context - Questionnaire of Cognitive Schema Activation in Sexual Context (QCSASC); sexual beliefs - Sexual Dysfunctional Beliefs Questionnaire (SDBQ); automatic thoughts and emotions presented during sexual activity - Sexual Modes Questionnaire (SMQ)); and sexual functioning (Female Sexual Function Index (FSFI)). Results indicated that most women with sexual dysfunction activate incompetence schemas when facing unsuccessful sexual situations. Additionally, lack of erotic thoughts and increased attentional focus on failure and disengagement thoughts during sexual activity were also common in the clinical sample. Besides these common factors, results showed that some specific cognitive and emotional factors are associated with different clinical presentations. Sexual conservative beliefs seem to be closely related to hypoactive sexual desire and to a certain extent to arousal difficulties in women. Body image beliefs and automatic thoughts focusing on self-body appearance seem to be strongly associated with orgasmic disorder. Regarding emotions, fear was one of the best predictors of vaginismus, whereas sadness, disillusion, guilt, and lack of pleasure and satisfaction were closely associated to hypoactive sexual desire. Overall, these findings may contribute to the discussion regarding the treatment strategies used for the different female sexual dysfunctions. PMID:18576234

    The major classes of chemicals and brain pathways involved in sexual arousal in mammals are well studied and are thought to be of an ancient, evolutionarily conserved origin. Here we discuss what is known of these neurochemicals and brain circuits in fishes, the oldest and most species-rich group of vertebrates from which tetrapods arose over 200 million years ago. Highlighted are case studies in vocal species where well-delineated sensory and motor pathways underlying reproductive-related behaviors illustrate the diversity and evolution of brain mechanisms driving sexual motivation between (and within) sexes. Also discussed are evolutionary insights from the neurobiology and reproductive behavior of elasmobranch fishes, the most ancient lineage of jawed vertebrates, which are remarkably similar in their reproductive biology to terrestrial mammals.

    This study used an experimental paradigm to investigate the roles of sexual victimization history and alcohol intoxication in young women's sexual-emotional responding and sexual risk taking. A nonclinical community sample of 436 young women, with both an instance of heavy episodic drinking and some HIV/STI risk exposure in the past year, completed childhood sexual abuse (CSA) and adolescent/adult sexual assault (ASA) measures. A majority of them reported CSA and/or ASA, including rape and attempted rape. After random assignment to a high alcohol dose (.10 %) or control condition, participants read and projected themselves into an eroticized scenario of a sexual encounter involving a new partner. As the story protagonist, each participant rated her positive mood and her sexual arousal, sensation, and desire, and then indicated her likelihood of engaging in unprotected sex. Structural equation modeling analyses revealed that ASA and alcohol were directly associated with heightened risk taking, and alcohol's effects were partially mediated by positive mood and sexual desire. ASA was associated with attenuated sexual-emotional responding and resulted in diminished risk taking via this suppression. These are the first findings indicating that, compared to non-victimized counterparts, sexually victimized women respond differently in alcohol-involved sexual encounters in terms of sexual-emotional responding and risk-taking intentions. Implications include assessing victimization history and drinking among women seeking treatment for either concern, particularly women at risk for HIV, and alerting them to ways their histories and behavior may combine to exacerbate their sexual risks.

    Objectives Sexual function is an important dimension of adult life and yet very little is known about the relationships between female sexuality and chronic health conditions, including pelvic floor disorders. Our goal was to investigate the hypothesis that pelvic floor disorders are associated with female sexual problems, independent of other related factors. Methods The study population included 301 adult women seeking outpatient gynecologic and urogynecologic care. Pelvic floor disorders were assessed with the Pelvic Floor Disorders Inventory-20 (PFDI) and the Pelvic Organ Prolapse Quantification examination. Sexual function was assessed with the Personal Experiences Questionnaire. Using ordinal regression analysis, we identified characteristics and conditions associated with decreased libido, infrequent orgasm, decreased arousal, and dyspareunia. Results Sexual function was poorer among 78 women (26%) without a current sexual partner than among 223 with a partner (p<0.01). Among the 223 with a current partner, women with a high PFDI score were significantly more likely to report decreased arousal (p<0.01), infrequent orgasm (p<0.01) and increased dyspareunia (p<0.01). A similar pattern was observed for the urinary, colorectal-anal, and prolapse scales of the PFDI, although some associations were marginally significant. Stage III–IV prolapse was significantly associated with infrequent orgasm (p=0.02), but other sexual complaints were not more common with increasing prolapse stage. Conclusion Pelvic floor symptoms are significantly associated with reduced sexual arousal, infrequent orgasm, and dyspareunia. Clinicians who care for women with pelvic floor disorders should be aware of this association and should specifically address sexual concerns with women seeking treatment of incontinence and prolapse.

    Male undergraduates were exposed to a videotaped depiction of heterosexual rape accompanied by one of three soundtracks: the original soundtrack (featuring dialogue and background rock music), relaxing music, or no sound. Subjective reports of sexual arousal, general enjoyment, perceived erotic content, and perceived pornographic content of the sequence were then provided by each subject. Results indicated that males exposed to the videotape accompanied by the original soundtrack found the sequence significantly more pornographic than males exposed to the sequence accompanied by either relaxing background music or no sound. Ratings of sexual arousal, general enjoyment, and the perceived erotic content, however, did not differ significantly across soundtrack conditions. These results are compatible with the assertion that the content of a video soundtrack may influence the impact of depicted sexual violence. PMID:3729702

    The past few years have seen an increased awareness of the relevance of studying the role of sexual response, emotion, and traits such as sensation seeking and the propensity for sexual inhibition in risky sexual behavior. The current study examined the association between self-reported sexual risk taking and psychophysiological response patterns in 76 heterosexual and homosexual men. Measures included genital, electrodermal, startle eyeblink, and cardiovascular responses, and stimuli included threatening (depicting coercive sexual interactions) and nonthreatening (depicting consensual sexual interactions) sexual film excerpts. Sexual risk taking was hypothesized to be associated with decreased inhibition of sexual arousal and hyporeactive affective and autonomic responses to threatening sexual stimuli. Controlling for age and number of sexual partners in the past year, sexual risk taking (number of partners during the past 3 years with whom no condoms were used) was found to be associated with stronger genital responses and smaller eyeblink responses to both threatening and nonthreatening sexual stimuli. Correlations between genital and subjective sexual arousal were relatively low. Sexual risk taking was related to sensation seeking but not to the propensity for sexual inhibition. The findings suggest that risky sexual behavior may involve a role for psychophysiological mechanisms that are specific to sex as well as for ones that are associated with more general approach/avoidance response tendencies.

    Previous studies suggest that severe sexual sadism and psychopathy are phenotypically different, although both are characterized by deficits in emotional processing. We assessed empathic capacity in a sample of 12 sexual sadists in comparison with 23 non-sadistic offenders using the Multifaceted Empathy Test (MET). All participants were forensic patients under mandatory treatment orders who had committed sexual offenses. The MET is a computerized rating task that differentiates and measures cognitive and emotional components of empathy, or perspective-taking versus compassionate components. To identify the effects of possible empathy deficits caused by psychopathic traits, we controlled both samples for psychopathy as a covariate, measured by the Psychopathy Checklist-Revised (PCL-R). According to our results, sexual sadists did not differ from non-sadistic sexual offenders with regard to emotional empathy for either positive or negative stimuli. The results suggest that severe sexual sadism is a distinct, pathological sexual arousal response, not a deficit in emotional processing. PMID:22417758

    Recent research suggesting that a high proportion of men and women remain sexually active well into later life refutes the prevailing myth that aging and sexual dysfunction are inexorably linked. Age-related physiological changes do not render a meaningful sexual relationship impossible or even necessarily difficult. In men, greater physical stimulation is required to attain and maintain erections, and orgasms are less intense. In women, menopause terminates fertility and produces changes stemming from estrogen deficiency. The extent to which aging affects sexual function depends largely on psychological, pharmacological, and illness-related factors. In this article I review the physiological sex-related changes that occur as part of the normal aging process in men and women. I also summarize the effects on sexual function of age-related psychological issues, illness factors, and medication use. An understanding of the sexual changes that accompany normal aging may help physicians give patients realistic and encouraging advice on sexuality. Although it is important that older men and women not fall into the psychosocial trap of expecting (or worse, trying to force) the kind and degree of sexual response characteristic of their youth, it is equally as important that they not fall prey to the negative folklore according to which decreased physical intimacy is an inevitable consequence of the passage of time.

    Sexual problems are often attributed to psychological or physical deficits that are difficult to modify, or to a poor lover. In contrast, the neurophysiological interaction between body and brain can be understood as fundamental for the genital and emotional experience of sexuality. Neuropsychological discoveries and clinical observations show that elevated muscle tension, superficial breathing and reduced body movement, as employed by many individuals during sexual arousal, will limit the perception of arousal and the degree of sexual pleasure. In contrast, deep breathing and variations in movement and muscle tension support it. Through the use of self awareness exercises and physical learning steps, patients can integrate their sexuality and increases its resistance to psychological, medical and relational interferences.

    Introduction Extinction involves an inhibitory form of new learning that is highly dependent on the context for expression. This is supported by phenomena such as renewal and spontaneous recovery, which may help explain the persistence of appetitive behavior, and related problems such as addictions. Research on these phenomena in the sexual domain is lacking, where it may help to explain the persistence of learned sexual responses. Method Men (n?=?40) and women (n?=?62) participated in a differential conditioning paradigm, with genital vibrotactile stimulation as US and neutral pictures as conditional stimuli (CSs). Dependent variables were genital and subjective sexual arousal, affect, US expectancy, and approach and avoid tendencies towards the CSs. Extinction and renewal of conditioned sexual responses were studied by context manipulation (AAA vs. ABA condition). Results No renewal effect of genital conditioned responding could be detected, but an obvious recovery of US expectancy following a context change after extinction (ABA) was demonstrated. Additionally, women demonstrated recovery of subjective affect and subjective sexual arousal. Participants in the ABA demonstrated more approach biases towards stimuli. Conclusions The findings support the context dependency of extinction and renewal of conditioned sexual responses in humans. This knowledge may have implications for the treatment of disturbances in sexual appetitive responses such as hypo- and hypersexuality. PMID:25170909

  3. Affective Arousal as Information: How Affective Arousal Influences Judgments, Learning, and Memory

    PubMed Central

    2014-01-01

    The affect-as-information framework posits that affect is embodied information about value and importance. The valence dimension of affect provides evaluative information about stimulus objects, which plays a role in judgment and decisionmaking. Affect can also provide evaluative information about one's own cognitions and response inclinations, information that guides thinking and reasoning. In particular, positive affect often promotes, and negative affect inhibits, accessible responses or dominant modes of thinking. Affect thus moderates many of the textbook phenomena in cognitive psychology. In the current review, we suggest additionally that the arousal dimension of affect amplifies reactions, leading to intensified evaluations, increased reliance on particular styles of learning, and enhanced long-term memory for events. We conclude that whereas valenced affective cues serve as information about value, the arousal dimension provides information about urgency or importance. PMID:25067943

    The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), Task Force has recently rejected the proposal to include coercive paraphilia as an official diagnosis, reaffirming that rape is a crime and not a mental disorder. We hope this will discourage what has been the inappropriate practice of giving rapists the made-up diagnosis of paraphilia, NOS, nonconsent, to facilitate their psychiatric commitment under sexually violent predator (SVP) statutes. Losing the paraphilia, NOS, option has tempted some SVP evaluators to overdiagnose sexual sadism, which is an official DSM mental disorder. To prevent this improper application and to clarify those rare instances in which this diagnosis might apply, we present a brief review of the research on sexual sadism; an annotation of its definitions that have been included in the DSM since the Third Edition, published in 1980, and in the International Classification of Diseases, Tenth Edition (ICD-10); and a two-step process for making a diagnostic decision. Rape and sexual sadism have in common violence, cruelty, and a callous indifference on the part of the perpetrator to the suffering of the victim, but they differ markedly in motivation. Rapists use violence to enforce the victim's cooperation, to express aggression, or both. In contrast, in sexual sadism, the violence, domination, and infliction of pain and humiliation are a preferred or necessary precondition for sexual arousal. Only a small proportion of rapists qualify for the diagnosis of sexual sadism. PMID:22960924

Despite their prevalence, these two disorders are often not addressed by healthcare providers and patients due their private and awkward nature. As physicians, we need to move beyond our own unease in order to adequately address our patients’ sexual problems and implement appropriate treatment. Using the Sexual Response Cycle as the model of the physiological changes of humans during sexual stimulation and the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition this article will review the current literature on the desire disorders focusing on prevalence, etiology, and treatment.

    The authors investigated the effects of violent portrayals in movie previews on viewers' arousal and anticipated enjoyment of movies based on their arousal-seeking tendencies. A total of 159 college students watched 6 movie previews, each in a violent or nonviolent version, and reported their expectations of enjoying watching the movies. The results show that high arousal seekers reported a higher level of anticipated enjoyment after watching the violent previews than the nonviolent previews. In contrast, low arousal seekers did not expect much difference in their enjoyment between the two versions. In line with the theory of optimal stimulation level, the results indicate that viewers' anticipated enjoyment of movies after watching violent images in previews is moderated by individuals' arousal-seeking tendencies.

    The effects of learning on sexual orientation are rarely addressed in the literature. At the very least, such processes provide a means of elaborating upon orientation predispositions. Some aspects of our mates may inherently elicit a sexual response, but other attributes do so only after sexual experience with them. Animal research shows robust, direct effects of conditioning processes on partner preference with a few studies showing plasticity in preference for sex of partner. Descriptive research in humans suggests effects of experience on partner preference and, although experimental demonstrations of human sexual conditioning are neither numerous nor robust, sexual arousal is conditionable in women and men. With modern developments in learning theory (e.g., expectancy learning and evaluative conditioning), it seems appropriate to renew the investigation of contributions and limitations of conditioning processes to explaining how cues acquire erotic value and to attempt some integration between the sexual conditioning literature and research on sexual orientation or more generally sexual partner preference.

    Emotion influences most aspects of cognition and behavior, but emotional factors are conspicuously absent from current models of word recognition. The influence of emotion on word recognition has mostly been reported in prior studies on the automatic vigilance for negative stimuli, but the precise nature of this relationship is unclear. Various models of automatic vigilance have claimed that the effect of valence on response times is categorical, an inverted-U, or interactive with arousal. The present study used a sample of 12,658 words, and included many lexical and semantic control factors, to determine the precise nature of the effects of arousal and valence on word recognition. Converging empirical patterns observed in word-level and trial-level data from lexical decision and naming indicate that valence and arousal exert independent monotonic effects: Negative words are recognized more slowly than positive words, and arousing words are recognized more slowly than calming words. Valence explained about 2% of the variance in word recognition latencies, whereas the effect of arousal was smaller. Valence and arousal do not interact, but both interact with word frequency, such that valence and arousal exert larger effects among low-frequency words than among high-frequency words. These results necessitate a new model of affective word processing whereby the degree of negativity monotonically and independently predicts the speed of responding. This research also demonstrates that incorporating emotional factors, especially valence, improves the performance of models of word recognition. PMID:24490848

    Previous research demonstrates that manipulating vision influences balance. Here, we question whether manipulating balance can influence vision and how it may influence vision, specifically the perception of width. In Experiment 1, participants estimated the width of beams while balanced and unbalanced. When unbalanced, participants judged the widths to be smaller. One possible explanation is that unbalanced participants did not view the stimulus as long as when balanced because they were focused on remaining balanced. In Experiment 2, we tested this notion by limiting viewing time. Experiment 2 replicated the findings of Experiment 1 but viewing time had no effect on width judgments. In Experiment 3, participants’ level of arousal was manipulated because the balancing task likely produced arousal. While jogging, participants judged the beams to be smaller. In Experiment 4, participants completed another arousing task (counting backward by 7s) that did not involve movement. Again, participants judged the beams to be smaller when aroused. Experiment 5a raised participants’ level of arousal before estimating the board widths (to control for potential dual-task effects) and found that heightened arousal still influenced perceived width of the boards. Collectively, heightened levels of arousal, caused by multiple manipulations (including balance), influenced perceived width. PMID:20952786

    Study Objectives: To compare changes in end-tidal CO2, genioglossus muscle activity and upper airway resistance following tone-induced arousal and the return to sleep in healthy individuals with small and large ventilatory responses to arousal. Design: Observational study. Setting: Two sleep physiology laboratories. Patients or Participants: 35 men and 25 women with no medical or sleep disorders. Interventions: Auditory tones to induce 3-s to 15-s cortical arousals from sleep. Measurements and Results: During arousal from sleep, subjects with large ventilatory responses to arousal had higher ventilation (by analytical design) and tidal volume, and more marked reductions in the partial pressure of end-tidal CO2 compared to subjects with small ventilatory responses to arousal. However, following the return to sleep, ventilation, genioglossus muscle activity, and upper airway resistance did not differ between high and low ventilatory response groups (Breath 1 on return to sleep: ventilation 6.7 ± 0.4 and 5.5 ± 0.3 L/min, peak genioglossus activity 3.4% ± 1.0% and 4.8% ± 1.0% maximum, upper airway resistance 4.7 ± 0.7 and 5.5 ± 1.0 cm H2O/L/s, respectively). Furthermore, dilator muscle activity did not fall below the pre-arousal sleeping level and upper airway resistance did not rise above the pre-arousal sleeping level in either group for 10 breaths following the return to sleep. Conclusions: Regardless of the magnitude of the ventilatory response to arousal from sleep and subsequent reduction in PETCO2, healthy individuals did not develop reduced dilator muscle activity nor increased upper airway resistance, indicative of partial airway collapse, on the return to sleep. These findings challenge the commonly stated notion that arousals predispose to upper airway obstruction.

    It is well-established that exposure to emotionally laden events initiates secretion of the arousal-related hormone epinephrine in the periphery. These neuroendocrine changes and the subsequent increase in peripheral physiological output play an integral role in modulating brain systems involved in memory formation. The impermeability of the blood brain barrier to epinephrine represents an important obstacle in understanding how peripheral hormones initiate neurochemical changes in the brain that lead to effective memory formation. This obstacle necessitated the identity of a putative pathway capable of conveying physiological changes produced by epinephrine to limbic structures that incorporate arousal and affect related information into memory. A major theme of the proposed studies is that ascending fibers of the vagus nerve may represent such a mechanism. This hypothesis was tested by evaluating the contribution of ascending vagal fibers in modulating memory for responses learned under behavioral conditions that produce emotional arousal by manipulating appetitive stimuli. A combination of electrophysiological recording of vagal afferent fibers and in vivo microdialysis was employed in a second study to simultaneously assess how elevations in peripheral levels of epinephrine affect vagal nerve discharge and the subsequent potentiation of norepinephrine release in the basolateral amygdala. The final study used double immunohistochemistry labeling of c-fos and dopamine beta hydroxylase (DBH), the enzyme for norepinephrine synthesis to determine if epinephrine administration alone or stimulation of the vagus nerve at an intensity identical to that which improved memory in Experiment 1 produces similar patterns of neuronal activity in brain areas involved in processing memory for emotional events. Findings emerging from this collection of studies establish the importance of ascending fibers of the vagus nerve as an essential pathway for conveying the peripheral consequences of physiological arousal on brain systems that encode new information into memory storage.

    Objective Although research has established childhood sexual abuse (CSA) as a risk factor for men’s perpetration of sexual aggression, there has been little investigation of the factors undergirding this association. This study represents one of the first to use a laboratory-based sexual aggression analogue coupled with an alcohol administration protocol to investigate the pathways through which CSA and alcohol influence men’s self-reported sexual aggression intentions. Method After completing background questionnaires, male social drinkers (N = 220) were randomly assigned to a control, placebo, low alcohol dose or high alcohol dose condition. Following beverage consumption, participants read a sexual scenario in which the female partner refused to have unprotected sexual intercourse, after which they completed dependent measures. Results Path analysis indicated that men with a CSA history and intoxicated men perceived the female character as more sexually aroused and reported stronger sexual entitlement cognitions, both of which were in turn associated with greater condom use resistance and higher sexual aggression intentions. Exploratory analyses revealed that intoxication moderated the effects of CSA history on sexual entitlement cognitions, such that sexual entitlement cognitions were highest for men who had a CSA history and consumed alcohol. Conclusions Findings suggest that CSA history may facilitate sexual assault perpetration through its effects on in-the-moment cognitions, and that these effects may be exacerbated by alcohol intoxication.

    Although sexual dysfunction is common in psychiatric patients, quantification of sexual dysfunction is limited by the paucity of validated, user-friendly scales. In order to address this problem, the authors have developed the Arizona Sexual Experiences Scale (ASEX), a five-item rating scale that quantifies sex drive, arousal, vaginal lubrication/penile erection, ability to reach orgasm, and satisfaction from orgasm. Possible total scores range from 5 to 30, with the higher scores indicating more sexual dysfunction.

    Previous studies have demonstrated variable influences of sexual hormonal states on female brain activation and the necessity to control for these in neuroimaging studies. However, systematic investigations of these influences, particularly those of hormonal contraceptives as compared to the physiological menstrual cycle are scarce. In the present study, we investigated the hormonal modulation of neural correlates of erotic processing in a group of females under hormonal contraceptives (C group; N?=?12), and a different group of females (nC group; N?=?12) not taking contraceptives during their mid-follicular and mid-luteal phases of the cycle. We used functional magnetic resonance imaging to measure hemodynamic responses as an estimate of brain activation during three different experimental conditions of visual erotic stimulation: dynamic videos, static erotic pictures, and expectation of erotic pictures. Plasma estrogen and progesterone levels were assessed in all subjects. No strong hormonally modulating effect was detected upon more direct and explicit stimulation (viewing of videos or pictures) with significant activations in cortical and subcortical brain regions previously linked to erotic stimulation consistent across hormonal levels and stimulation type. Upon less direct and less explicit stimulation (expectation), activation patterns varied between the different hormonal conditions with various, predominantly frontal brain regions showing significant within- or between-group differences. Activation in the precentral gyrus during the follicular phase in the nC group was found elevated compared to the C group and positively correlated with estrogen levels. From the results we conclude that effects of hormonal influences on brain activation during erotic stimulation are weak if stimulation is direct and explicit but that female sexual hormones may modulate more subtle aspects of sexual arousal and behaviour as involved in sexual expectation. Results may provide a basis for future imaging studies on sexual processing in females, especially in the context of less explicit erotic stimulation. PMID:23418428

    Previous research using the Mood and Sexuality Questionnaire (MSQ) has revealed substantial variability in how negative mood impacts sexual response and behavior. However, the MSQ does not address differences between desire for solo or partnered sexual activity, examine the effects of sexual activity on mood, or assess the effects of positive mood. This paper presents the development and factor structure of the Revised Mood and Sexuality Questionnaire (MSQ-R). An exploratory factor analysis in a sample of heterosexual men, homosexual men, and heterosexual women (N = 1983) produced 8 factors. Considerable variability was found in how moods influence sexual desire and arousal, in the effects of mood on sexual behavior, and in the reciprocal effects of sexual activity on mood. Among other findings, heterosexual women were less likely than heterosexual and homosexual men to experience increased sexual desire and arousal when anxious or stressed, whereas homosexual men and heterosexual women were less likely than heterosexual men to experience increased desire when sad or depressed. Heterosexual men and women were more likely than homosexual men to report increased desire when in a positive mood. Intercorrelations and correlations with various sexual behaviors varied by group. Limitations and implications of the findings are discussed. PMID:22963331

    Most studies on physiological effects of emotion-inducing images and sounds examine stimulus locked variables reflecting a state of at most a few seconds. We here aimed to induce longer lasting emotional states using blocks of repetitive visual, auditory, and bimodal stimuli corresponding to specific valence and arousal levels. The duration of these blocks enabled us to reliably measure heart rate variability as a possible indicator of arousal. In addition, heart rate and skin conductance were determined without taking stimulus timing into account. Heart rate was higher for pleasant and low arousal stimuli compared to unpleasant and high arousal stimuli. Heart rate variability and skin conductance increased with arousal. Effects of valence and arousal on cardiovascular measures habituated or remained the same over 2-min intervals whereas the arousal effect on skin conductance increased. We did not find any effect of stimulus modality. Our results indicate that blocks of images and sounds of specific valence and arousal levels consistently influence different physiological parameters. These parameters need not be stimulus locked. We found no evidence for differences in emotion induction between visual and auditory stimuli, nor did we find bimodal stimuli to be more potent than unimodal stimuli. The latter could be (partly) due to the fact that our bimodal stimuli were not optimally congruent. PMID:23801957

    Sustaining and strengthening the ability of the elderly to continue their sexual needs can be realized as part of improving their quality of life, health and well-being. There is no age at which ends the expression of sexuality and intimacy. Through education, quality of life and advances in medicine, the average life expectancy is still increasing. Sexual activity of older people society usually describe using pejorative terms as an inappropriate, bizarre or obscene, but these labels are different than reality. Hormonal changes and other physiological changes associated with aging affect sexual interest. Erectile dysfunction is a problem in men increasing with age. There is no evidence that premature ejaculation is more common in older age. Cross-sectional studies showed no difference in sexual dysfunction between older and younger women. Age is not a barrier to sexually transmitted diseases. The most common pathogenetic factors for male erectile dysfunction are vascular diseases. In women, the most important symptoms of sexual dysfunction are lack of emotional wellbeing and a sense of intimacy during sexual intercourse. PMID:25815611

    This study investigates an extension of H.J. Eysenck's [Eysenck, H.J., 1967. The Biological Basis of Personality. Charles C. Thomas, Springfield, IL] arousal theory of extraversion, incorporating an effort system as a control system for different aspects of arousal. Extraverts were expected to have lower levels of reticocortical arousal than introverts, to invest more effort, and to have lower task performance in a monotonous vigilance task. In a 40-min vigilance task, participants had to react to the shorter of two 1 kHz tones presented binaurally at an event rate of 200 per 10 min. Spontaneous EEG, event-related potential, and performance data of 40 extremely introverted and 41 extremely extraverted students were available for statistical analysis. A tendency for lower arousal levels of extraverts (alpha 2 band), the expected higher effort investment (P300) and a lower performance (hits) of extraverts were found. PMID:16426692

    The aim of the present study was to investigate sexual behavior in population of psychiatric patients affected by schizophrenia, schizoaffective disorder or bipolar disorder by means of an ad hoc questionnaire designed to explore the three phases of the sexual response: desire (or interest), arousal, and performance. The study assessed patients' attitude toward sexuality, several aspects of their sexual behavior, including patients' awareness of the risk of sexually transmitted diseases (STD), contraceptive strategy preferred by patients, and sexual effects of psychotropic medication. Patients reported a high frequency of sexual dysfunction, in particular, hyposexuality. Schizophrenia diagnosis and female gender were associated with lower levels of sexual performance. The impact of psychotropic drugs on patients' sexuality was significant, with both positive and negative effects. Although 65.8% of patients reported to be concerned about the risk of contracting infections during sexual intercourse, most of them engaged in sexual behavior at high risk for acquisition and transmission of STD. Patients' compliance with contraceptive measures was poor. PMID:12711402

    In a recent paper published in the Journal of Child Sexual Abuse, we assessed the differences between sexually victimized and nonsexually victimized male adolescent sexual abusers ( Burton, Duty, & Leibowitz, 2011 ). We found that the sexually victimized group had more severe developmental antecedents (e.g., trauma and early exposure to pornography) and behavioral difficulties (sexual aggression, arousal, pornography use, and nonsexual offenses). The present study compares sexually victimized and nonsexually victimized adolescent sexual abusers with a group of nonsexually victimized delinquent youth. Findings included that delinquent youth had fewer behavioral and developmental problems than the comparison groups. In addition, sexually victimized sexual abusers had the highest mean scores on trauma and personality measures. Implications for research and treatment are offered. PMID:22574846

    Arousal and consciousness flexibly adjust to salient cues, but remain stable despite noise and disturbance. Diverse, highly interconnected neural networks govern the underlying transitions of behavioral state; these networks are robust but very complex. Frameworks from systems engineering provide powerful tools for understanding functional logic behind component complexity. From a general systems viewpoint, a minimum of three communicating control modules may enable flexibility and stability to coexist. Comparators would subtract current arousal from desired arousal, producing an error signal. Regulators would compute control signals from this error. Generators would convert control signals into arousal, which is fed back to comparators, to make the system noise-proof through self-correction. Can specific neurons correspond to these control elements? To explore this, here we consider the brain-wide orexin/hypocretin network, which is experimentally established to be vital for flexible and stable arousal. We discuss whether orexin neurons may act as comparators, and their target neurons as regulators and generators. Experiments are proposed for testing such predictions, based on computational simulations showing that comparators, regulators, and generators have distinct temporal signatures of activity. If some regulators integrate orexin-communicated errors, robust arousal control may be achieved via integral feedback (a basic engineering strategy for tracking a set-point despite noise). An integral feedback view also suggests functional roles for specific molecular aspects, such as differing life-spans of orexin peptides. The proposed framework offers a unifying logic for molecular, cellular, and network details of arousal systems, and provides insight into behavioral state transitions, complex behavior, and bases for disease.

    2005-08-10

    Sleep and arousal are known to be regulated by both homeostatic and circadian processes, but the underlying molecular mechanisms are not well understood. It has been reported that the Drosophila rest/activity cycle has features in common with the mammalian sleep/wake cycle, and it is expected that use of the fly genetic model will facilitate a molecular understanding of sleep and arousal. Here, we report the phenotypic characterization of a Drosophila rest/activity mutant known as fumin (fmn). We show that fmn mutants have abnormally high levels of activity and reduced rest (sleep); genetic mapping, molecular analyses, and phenotypic rescue experiments demonstrate that these phenotypes result from mutation of the Drosophila dopamine transporter gene. Consistent with the rest phenotype, fmn mutants show enhanced sensitivity to mechanical stimuli and a prolonged arousal once active, indicating a decreased arousal threshold. Strikingly,fmn mutants do not show significant rebound in response to rest deprivation as is typical for wild-type flies, nor do they show decreased life span. These results provide direct evidence that dopaminergic signaling has a critical function in the regulation of insect arousal. PMID:16093388

    Humans, and many non-human animals, produce and respond to harsh, unpredictable, nonlinear sounds when alarmed, possibly because these are produced when acoustic production systems (vocal cords and syrinxes) are overblown in stressful, dangerous situations. Humans can simulate nonlinearities in music and soundtracks through the use of technological manipulations. Recent work found that film soundtracks from different genres differentially contain such sounds. We designed two experiments to determine specifically how simulated nonlinearities in soundtracks influence perceptions of arousal and valence. Subjects were presented with emotionally neutral musical exemplars that had neither noise nor abrupt frequency transitions, or versions of these musical exemplars that had noise or abrupt frequency upshifts or downshifts experimentally added. In a second experiment, these acoustic exemplars were paired with benign videos. Judgements of both arousal and valence were altered by the addition of these simulated nonlinearities in the first, music-only, experiment. In the second, multi-modal, experiment, valence (but not arousal) decreased with the addition of noise or frequency downshifts. Thus, the presence of a video image suppressed the ability of simulated nonlinearities to modify arousal. This is the first study examining how nonlinear simulations in music affect emotional judgements. These results demonstrate that the perception of potentially fearful or arousing sounds is influenced by the perceptual context and that the addition of a visual modality can antagonistically suppress the response to an acoustic stimulus.

  1. Pupil-Linked Arousal Determines Variability in Perceptual Decision Making

    2014-01-01

    Decision making between several alternatives is thought to involve the gradual accumulation of evidence in favor of each available choice. This process is profoundly variable even for nominally identical stimuli, yet the neuro-cognitive substrates that determine the magnitude of this variability are poorly understood. Here, we demonstrate that arousal state is a powerful determinant of variability in perceptual decision making. We measured pupil size, a highly sensitive index of arousal, while human subjects performed a motion-discrimination task, and decomposed task behavior into latent decision making parameters using an established computational model of the decision process. In direct contrast to previous theoretical accounts specifying a role for arousal in several discrete aspects of decision making, we found that pupil diameter was uniquely related to a model parameter representing variability in the rate of decision evidence accumulation: Periods of increased pupil size, reflecting heightened arousal, were characterized by greater variability in accumulation rate. Pupil diameter also correlated trial-by-trial with specific patterns of behavior that collectively are diagnostic of changing accumulation rate variability, and explained substantial individual differences in this computational quantity. These findings provide a uniquely clear account of how arousal state impacts decision making, and may point to a relationship between pupil-linked neuromodulation and behavioral variability. They also pave the way for future studies aimed at augmenting the precision with which people make decisions. PMID:25232732

    Mammalian hibernation is a natural, fully reversible hypometabolic state characterized by a drastic reduction of body temperature and metabolic activity, which ensures survival to many species under adverse environmental conditions. During hibernation, many hibernators rely for energy supply almost exclusively on lipid reserves; the shift from carbohydrate to lipid metabolism implies profound rearrangement of the anabolic and catabolic pathways of energetic substrates. However, the structural counterpart of such adaptation is not known. In this study we investigated, by using immunoelectron microscopy, the fine intracellular distribution of two key enzymes involved in lipid metabolism, namely, the fatty acid synthase (FAS) and the long-chain fatty acyl-CoA synthetase (ACSL), in hepatocytes of euthermic, hibernating and arousing hazel dormice. Our results show that the two enzymes are differentially distributed in cellular compartments (cytoplasm, mitochondria and cell nuclei) of hepatocytes during euthermia. Quantitative redistribution of both enzymes among cellular compartments takes place during hibernation and arousal, in accordance with the physiological changes. Interestingly, this redistribution follows different seasonal patterns in cytoplasm, mitochondria and nuclei. In conclusion, our data represent the first quantitative morphological evidence of lipid enzyme distribution in a true hibernator throughout the year cycle, thus providing a structural framework to biochemical changes associated with the hypometabolism of hibernation.

    The simultaneous revision of the two major international classifications of disease, the Diagnostic and Statistical Manual of Mental Disorders and the International Classification of Diseases, serves as an opportunity to observe the dynamic processes through which social norms of sexuality are constructed and are subject to change in relation to social, political, and historical context. This article argues that the classifications of sexual disorders, which define pathological aspects of "sexually arousing fantasies, sexual urges or behaviors" are representations of contemporary sexual norms, gender identifications, and gender relations. It aims to demonstrate how changes in the medical treatment of sexual perversions/paraphilias passed, over the course of the 20th century, from a model of pathologization (and sometimes criminalization) of non-reproductive sexual behaviors to a model that reflects and privileges sexual well-being and responsibility, and pathologizes the absence or the limitation of consent in sexual relations.

    2013-01-01

    It is widely held that negative emotions such as threat, anxiety, and disgust represent the core psychological factors that enhance conservative political beliefs. We put forward an alternative hypothesis: that conservatism is fundamentally motivated by arousal, and that, in this context, the effect of negative emotion is due to engaging intensely arousing states. Here we show that study participants agreed more with right but not left-wing political speeches after being exposed to positive as well as negative emotion-inducing film-clips. No such effect emerged for neutral-content videos. A follow-up study replicated and extended this effect. These results are consistent with the idea that emotional arousal, in general, and not negative valence, specifically, may underlie political conservatism. PMID:24376687

    Which emotions underlie our positive experiences of art? Although recent evidence from neuroscience suggests that emotions play a critical role in art perception, no research to date has explored the extent to which specific emotional states affect aesthetic experiences or whether general physiological arousal is sufficient. Participants were assigned to one of five conditions-sitting normally, engaging in 15 or 30 jumping jacks, or viewing a happy or scary video-prior to rating abstract works of art. Only the fear condition resulted in significantly more positive judgments about the art. These striking findings provide the first evidence that fear uniquely inspires positively valenced aesthetic judgments. The results are discussed in the context of embodied cognition. PMID:22309722

  11. Is the torpor-arousal cycle of hibernation controlled by a non-temperature-compensated circadian clock?

    PubMed

    Malan, André

    2010-06-01

    During the hibernation season, mammalian hibernators alternate between prolonged bouts of torpor with a reduced body temperature (Tb) and short arousals with a return to euthermy. Evidence is presented here to show that this metabolic-and also physiological and neuroanatomical-rhythm is controlled by a clock, the torpor-arousal (TA) clock. The temperature dependence of torpor bout duration in 3 species of Spermophilus (published data) may be described by assuming that the TA clock is a circadian clock (probably not the suprachiasmatic clock) that has lost its temperature compensation. This loss might result either from a permanent deletion, or more likely from a seasonal epigenetic control at the level of the clock gene machinery. This hypothesis was verified over the full Tb range on published data from 5 other species (a monotreme, a marsupial, and 3 placental mammals). In a hibernation season, instantaneous subjective time of the putative TA clock was summated over each torpor bout. For each animal, torpor bout length (TBL) was accurately predicted as a constant fraction of a subjective day, for actual durations in astronomical time varying between 4 and 13 to 20 days. The resulting temperature dependence of the interval between arousals predicts that energy expenditure over the hibernation season will be minimal when Tb is as low as possible without eliciting cold thermogenesis.

    Pornography has become a primary source of sexual education. At the same time, mainstream commercial pornography has coalesced around a relatively homogenous script involving violence and female degradation. Yet, little work has been done exploring the associations between pornography and dyadic sexual encounters: What role does pornography play inside real-world sexual encounters between a man and a woman? Cognitive script theory argues media scripts create a readily accessible heuristic model for decision-making. The more a user watches a particular media script, the more embedded those codes of behavior become in their worldview and the more likely they are to use those scripts to act upon real life experiences. We argue pornography creates a sexual script that then guides sexual experiences. To test this, we surveyed 487 college men (ages 18-29 years) in the United States to compare their rate of pornography use with sexual preferences and concerns. Results showed the more pornography a man watches, the more likely he was to use it during sex, request particular pornographic sex acts of his partner, deliberately conjure images of pornography during sex to maintain arousal, and have concerns over his own sexual performance and body image. Further, higher pornography use was negatively associated with enjoying sexually intimate behaviors with a partner. We conclude that pornography provides a powerful heuristic model which is implicated in men's expectations and behaviors during sexual encounters. PMID:25466233

    White-nose syndrome (WNS) is an emerging infectious disease of hibernating bats linked to the death of an estimated 5.7 million or more bats in the northeastern United States and Canada. White-nose syndrome is caused by the cold-loving fungus Pseudogymnoascus destructans (Pd), which invades the skin of the muzzles, ears, and wings of hibernating bats. Previous work has shown that WNS-affected bats arouse to euthermic or near euthermic temperatures during hibernation significantly more frequently than normal and that these too-frequent arousals are tied to severity of infection and death date. We quantified the behavior of bats during these arousal bouts to understand better the causes and consequences of these arousals. We hypothesized that WNS-affected bats would display increased levels of activity (especially grooming) during their arousal bouts from hibernation compared to WNS-unaffected bats. Behavior of both affected and unaffected hibernating bats in captivity was monitored from December 2010 to March 2011 using temperature-sensitive dataloggers attached to the backs of bats and infrared motion-sensitive cameras. The WNS-affected bats exhibited significantly higher rates of grooming, relative to unaffected bats, at the expense of time that would otherwise be spent inactive. Increased self-grooming may be related to the presence of the fungus. Elevated activity levels in affected bats likely increase energetic stress, whereas the loss of rest (inactive periods when aroused from torpor) may jeopardize the ability of a bat to reestablish homeostasis in a number of physiologic systems.

    The ultimate goal of research efforts directed at underload, boredom, or complacency in high-technology work environments is to detect conditions or states of the operator that can be demonstrated to lead to performance degradation, and then to intervene in the environment to restore acceptable system performance. Physiological measures may provide indices of changes in condition or state of the operator that may be of value in high-technology work environments. The focus of the present study was on the use of physiological measures in the assessment of operator condition or state in a task underload scenario. A fault acknowledgement task characterized by simple repetitive responses with minimal novelty, complexity, and uncertainty was employed to place subjects in a task underload situation. Physiological measures (electrocardiogram (ECG), electroencephalogram (EEG), and pupil diameter) were monitored during task performance over a one-hour test session for 12 subjects. Each of the physiological measures exhibited changes over the test session indicative of decrements in subject arousal level. While high correlations between physiological measures were found across subjects, individual differences between subjects support the use of profiling techniques to establish baselines unique to each subject.

    Background Previous research has demonstrated a relationship between memory recall and P300 amplitude in list learning tasks, but the variables mediating this P300-recall relationship are not well understood. In the present study, subjects were required to recall items from lists consisting of 12 words, which were presented in front of pictures taken from the IAPS collection. One word per list is made distinct either by font color or by a highly arousing background IAPS picture. This isolation procedure was first used by von Restorff. Brain potentials were recorded during list presentation. Results Recall performance was enhanced for color but not for emotional isolates. Event-related brain potentials (ERP) showed a more positive P300-component for recalled non-isolated words and color-isolated words, compared to the respective non-remembered words, but not for words isolated by arousing background. Conclusion Our findings indicate that it is crucial to take emotional mediator variables into account, when using the P300 to predict later recall. Highly arousing environments might force the cognitive system to interrupt rehearsal processes in working memory, which might benefit transfer into other, more stable memory systems. The impact of attention-capturing properties of arousing background stimuli is also discussed. PMID:16863589

    Background Young people in European countries are experiencing high levels of alcohol and drug use and escalating levels of sexually transmitted infections. Individually these represent major public health priorities. Understanding of the association between sex and substance use, and specifically the strategic roles for which young people utilise substances to facilitate sexual activity, remains limited. Methods Respondent driven sampling methodology was used in nine European cities to survey 1,341 16–35 year olds representing youth and younger adults who routinely engage in nightlife. Participants self-completed questionnaires, designed to gather demographic, social, and behavioural data on historic and current substance use and sexual behaviour. Results Respondents reported strategic use of specific substances for different sexual purposes. Substances differed significantly in the purposes for which each was deployed (e.g. 28.6% of alcohol users use it to facilitate sexual encounters; 26.2% of cocaine users use it to prolong sex) with user demographics also relating to levels of sexual use (e.g. higher levels of: ecstasy use by males to prolong sex; cocaine use by single individuals to enhance sensation and arousal). Associations between substance use and sex started at a young age, with alcohol, cannabis, cocaine or ecstasy use before age 16 all being associated with having had sex before the age of 16 (odds ratios, 3.47, 4.19, 5.73, 9.35 respectively). However, sexes differed and substance use under 16 years was associated with a proportionately greater increase in early sex amongst girls. Respondents' current drug use was associated with having multiple sexual partners. Thus, for instance, regular cocaine users (c.f. never users) were over five times more likely to have had five or more sexual partners in the last 12 months or have paid for sex. Conclusion An epidemic of recreational drug use and binge drinking exposes millions of young Europeans to routine consumption of substances which alter their sexual decisions and increase their chances of unsafe and regretted sex. For many, substance use has become an integral part of their strategic approach to sex, locking them into continued use. Tackling substances with both physiological and psychological links to sex requires approaching substance use and sexual behaviour in the same way that individuals experience them; as part of the same social process.

    We present a series of experiments that explore the boundary conditions for how emotional arousal influences height estimates. Four experiments are presented, which investigated the influence of context, situation-relevance, intensity, and attribution of arousal on height estimates. In Experiment 1, we manipulated the environmental context to signal either danger (viewing a height from above) or safety (viewing a height from below). High arousal only increased height estimates made from above. In Experiment 2, two arousal inductions were used that contained either 1) height-relevant arousing images or 2) height-irrelevant arousing images. Regardless of theme, arousal increased height estimates compared to a neutral group. In Experiment 3, arousal intensity was manipulated by inserting an intermediate or long delay between the induction and height estimates. A brief, but not a long, delay from the arousal induction served to increase height estimates. In Experiment 4, an attribution manipulation was included, and those participants who were made aware of the source of their arousal reduced their height estimates compared to participants who received no attribution instructions. Thus, arousal that is attributed to its true source is discounted from feelings elicited by the height, thereby reducing height estimates. Overall, we suggest that misattributed, embodied arousal is used as a cue when estimating heights from above that can lead to overestimation. PMID:24699393

    This study examined the sexual functioning of single adults (61 men, 68 women) with high functioning autism and Asperger syndrome living in the community with and without prior relationship experience. Participants completed an on-line questionnaire assessing autism symptoms, psychological functioning, and various aspects of sexual functioning. In general participants reported positive sexual functioning. Participants without prior relationship experience were significantly younger and more likely to be male and identify as heterosexual. They reported significantly higher sexual anxiety, lower sexual arousability, lower dyadic desire, and fewer positive sexual cognitions. The men reported better sexual function than did the women in a number of areas. These results counter negative societal perceptions about the sexuality of high functioning individuals on the autism spectrum. PMID:23526036

    Phallometric testing, or penile plethysmography (PPG), is an objective measure of sexual arousal for males. While extensive research on the reliability and validity of PPG has promoted its reputation as the "gold standard" of objective measurement of sexual arousal, there is a lack of standardization of stimulus sets and interpretation of results between sites. This article describes the laboratory protocol employed for PPG at the Royal Ottawa Mental Health Centre's Sexual Behaviours Clinic (SBC) in Ottawa, Ontario, as well as those used by the Sexual Behaviors Clinic and Lab (SBCL) in the Community and Public Safety Psychiatry Division (CPSPD) of the Department of Psychiatry and Behavioral Sciences at Medical University of South Carolina (MUSC) in Charleston, South Carolina.

    Health Issue Much attention is devoted to women's reproductive health, but the formative and mature stages of women's sexual lives are often overlooked. We have analyzed cross-sectional data from the Sexual Behaviour module of the 2000/2001 Canadian Community Health Survey (CCHS), and reviewed the literature and available indicators of the sexual health of Canadian women. Key Findings Contemporary Canadian adolescents are becoming sexually active at younger ages than in previous generations. The gender gap between young males and females in age at first intercourse has virtually disappeared. The mean age at first intercourse for CCHS respondents aged 15–24 years was between 16 and 17. Canadian-born respondents are significantly younger at first intercourse than those who were born outside of Canada. Few adolescents recognize important risks to their sexual health. Older Canadians are sexually active, and continue to find emotional and physical satisfaction in their sexual relationships. Data Gaps and Recommendations Both health surveys and targeted research must employ a broader understanding of sexuality to measure changes in and determinants of the sexual health of Canadians. There is reluctance to direct questions about sexual issues to younger Canadians, even though increased knowledge of sexual health topics is associated with delayed onset of sexual intercourse. Among adults, sex-positive resources are needed to address aspects of aging, rather than medicalizing age-related sexual dysfunction. Age and gender-appropriate sexual health care, education, and knowledge are important not only for women of reproductive age, but for Canadians at all stages of life. PMID:15345087

    2013-10-01

    Prior research has demonstrated that semantic organization in the right hemisphere (RH) is more diffuse and specialized for distant semantic associates than is semantic organization in the left hemisphere (LH). The present research explored individual differences in this regard. If the RH is more specialized for distant semantic associates, then individuals with a more active RH should display greater activation of distant semantic associations. Two experiments were conducted to examine this issue. In both studies a line bisection task was used to assess arousal asymmetry. In Experiment 1, greater RH activation was associated with the ability to generate remote associates to three word stimuli. In Experiment 2, relatively greater RH activation was associated with enhanced priming of distant semantic associates. Taken together, these experiments demonstrate that arousal asymmetry is an individual difference variable that is related to variability in semantic organization and retrieval. PMID:23867738

    Pathways mediating the generation and/or maintenance of sleep reside within the preoptic/anterior hypothalamus (POAH). Reproduction, water balance, thermoregulation, and neuroendocrine functions are also associated with POAH, but it is not fully understood whether sleep is consolidated with these behavioral and physiological functions, or whether sleep-related circuitry is segregated from other POAH regions. Recent studies indicate that sleep mechanisms may be localized to the ventrolateral preoptic area (VLPO) and that this region sends inhibitory projections to waking/arousal-related neurons in the histaminergic tuberomammillary nucleus (TM), the noradrenergic locus coeruleus (LC), and the serotonergic dorsal raphe (DR). The present study is a quantitative investigation of preoptic area efferents to these monoaminergic groups. The results demonstrate that biotinylated dextran injections in the VLPO region reveal a robust innervation of TM that was as much as five times greater than innervation derived from other POAH subregions. The innervation of TM originated almost exclusively from injection sites in the region of galanin neurons. VLPO projections to the LC were moderately dense and were greater than in other POAH regions except for equivalent input from the medial preoptic area. Projections to the dorsal raphe were equivalent to LC innervation and were generally two to three times greater from VLPO than from other POAH regions, except for projections from the lateral preoptic region, which were similar in magnitude. The rostral and caudal levels projected more to the TM, whereas the midrostral region of VLPO strongly innervated the LC core. These findings, with recent studies demonstrating medial and lateral extensions of the sleep-related VLPO neuronal group, indicate that descending arousal state control may be mediated by this specific galaninergic/gamma-aminobutyric acid (GABA)ergic cell group.

    The underlying neurobiological factors involved in sexual orientation are largely unknown. This study investigated whether neural circuits or different cognitive processes accounted for differences in brain activation in 14 heterosexual and 14 homosexual males. Brain scans were undertaken in each subject using functional magnetic resonance imaging while they viewed different sexual stimuli, i.e. heterosexual couple stimuli (HCS), gay couple stimuli (GCS), lesbian couple stimuli (LCS) and neutral stimuli (NS). Ratings of sexual attractiveness of the stimuli were assessed. Subjective sexual arousal was induced by HCS and GCS in heterosexual and homosexual men, respectively. Sexual disgust was induced by GCS and LCS in heterosexual and homosexual men, respectively. Compared with viewing NS, viewing sexual stimuli induced significantly different brain activations, most of which had the characteristics of cognitive processes. These observations suggest that different cognitive patterns may be the major cause of different subjective responses to sexual stimuli between heterosexual and homosexual men. PMID:21672322

    Emotion regulation research has shown successful altering of unwanted aversive emotional reactions. Cognitive strategies can also regulate expectations of reward arising from conditioned stimuli. However, less is known about the efficacy of such strategies with expectations elicited by conditioned appetitive sexual stimuli, and possible sex differences therein. In the present study it was examined whether a cognitive strategy (attentional deployment) could successfully down-regulate sexual arousal elicited by sexual reward-conditioned cues in men and women. A differential conditioning paradigm was applied, with genital vibrostimulation as unconditioned stimulus (US) and sexually relevant pictures as conditional stimuli (CSs). Evidence was found for emotion down-regulation to effect extinction of conditioned sexual responding in men. In women, the emotion down-regulatory strategy resulted in attenuated conditioned approach tendencies towards the CSs. The findings support that top-down modulation may indeed influence conditioned sexual responses. This knowledge may have implications for treating disturbances in sexual appetitive responses.

    Asexuality is an emerging identity category that challenges the common assumption that everyone is defined by some type of sexual attraction. Asexuals--those who report feeling no sexual attraction to others--constitute one percent of the population, according to one prominent study. In recent years, some individuals have begun to identify as asexual and to connect around their experiences interacting with a sexual society. Asexuality has also become a protected classification under the antidiscrimination law of one state and several localities, but legal scholarship has thus far neglected the subject. This Article introduces asexuality to the legal literature as a category of analysis, an object of empirical study, and a phenomenon of medical science. It then offers a close examination of the growing community of self-identified asexuals. Asexual identity has revealing intersections with the more familiar categories of gender, sexual orientation, and disability, and inspires new models for understanding sexuality. Thinking about asexuality also sheds light on our legal system. Ours is arguably a sexual law, predicated on the assumption that sex is important. This Article uses asexuality to develop a framework for identifying the ways that law privileges sexuality. Across various fields, these interactions include legal requirements of sexual activity, special carve-outs to shield sexuality from law, legal protections from others' sexuality, and legal protections for sexual identity. Applying this framework, the Article traces several ways that our sexual law burdens, and occasionally benefits, asexuals. This Article concludes by closely examining asexuality's prospects for broader inclusion into federal, state, and local antidiscrimination laws. PMID:24654293

    One of the essential tasks of neuropsychoanalysis is to investigate the neural correlates of sexual drives. Here, we consider the four defining characteristics of sexual drives as delineated by Freud: their pressure, aim, object, and source. We systematically examine the relations between these characteristics and the four-component neurophenomenological model that we have proposed based on functional neuroimaging studies, which comprises a cognitive, a motivational, an emotional and an autonomic/neuroendocrine component. Functional neuroimaging studies of sexual arousal (SA) have thrown a new light on the four fundamental characteristics of sexual drives by identifying their potential neural correlates. While these studies are essentially consistent with the Freudian model of drives, the main difference emerging between the functional neuroimaging perspective on sexual drives and the Freudian theory relates to the source of drives. From a functional neuroimaging perspective, sources of sexual drives, conceived by psychoanalysis as processes of excitation occurring in a peripheral organ, do not seem, at least in adult subjects, to be an essential part of the determinants of SA. It is rather the central processing of visual or genital stimuli that gives to these stimuli their sexually arousing and sexually pleasurable character. Finally, based on functional neuroimaging results, some possible improvements to the psychoanalytic theory of sexual drives are suggested. PMID:24672467

    Increased memory for emotional stimuli is a well-documented phenomenon. Emotional arousal during the encoding of a stimulus is one mediator of this memory enhancement. Other variables such as semantic relatedness also play a role in the enhanced memory for emotional stimuli, especially for verbal stimuli. Research has not addressed the contributions of emotional arousal, indexed by self-report and autonomic measures, and semantic relatedness on memory performance. Twenty young adults (10 women) were presented neutral-unrelated words, school-related words, moderately arousing emotional words, and highly arousing taboo words while heart rate and skin conductance were measured. Memory was tested with free recall and recognition tests. Results showed that taboo words, which were both semantically related and high arousal were remembered best. School-related words, which were high on semantic relatedness but low on arousal, were remembered better than the moderately arousing emotional words and semantically unrelated neutral words. Psychophysiological responses showed that within the moderately arousing emotional and neutral word groups, those words eliciting greater autonomic activity were better remembered than words that did not elicit such activity. These results demonstrate additive effects of semantic relatedness and emotional arousal on memory. Relatedness confers an advantage to memory (as in the school-words), but the combination of relatedness and arousal (as in the taboo words) results in the best memory performance. PMID:16427713

    Introduction A number of questionnaires have been created to assess levels of sexual desire in women, but to our knowledge, there are currently no validated measures for assessing cues that result in sexual desire. A questionnaire of this nature could be useful for both clinicians and researchers, because it considers the contextual nature of sexual desire and it draws attention to individual differences in factors that can contribute to sexual desire. Aim The aim of the present study was to create a multidimensional assessment tool of cues for sexual desire in women that is validated in women with and without hypoactive sexual desire disorder (HSDD). Methods Factor analyses conducted on both an initial sample (N = 874) and a community sample (N = 138) resulted in the Cues for Sexual Desire Scale (CSDS) which included four factors: (i) Emotional Bonding Cues; (ii) Erotic/ Explicit Cues; (iii) Visual/Proximity Cues; and (iv) Implicit/Romantic Cues. Main Outcome Measures Scale construction of cues associated with sexual desire and differences between women with and without sexual dysfunction. Results The CSDS demonstrated good reliability and validity and was able to detect significant differences between women with and without HSDD. Results from regression analyses indicated that both marital status and level of sexual functioning predicted scores on the CSDS. The CSDS provided predictive validity for the Female Sexual Function Index desire and arousal domain scores, and increased cues were related to a higher reported frequency of sexual activity in women. Conclusions The findings from the present study provide valuable information regarding both internal and external triggers that can result in sexual desire for women. We believe that the CSDS could be beneficial in therapeutic settings to help identify cues that do and do not facilitate sexual desire in women with clinically diagnosed desire difficulties.

    Objective Sexual orientation is usually considered to be determined in early life and stable in the course of adulthood. In contrast, some transgender individuals report a change in sexual orientation. A common reason for this phenomenon is not known. Methods We included 115 transsexual persons (70 male-to-female “MtF” and 45 female-to-male “FtM”) patients from our endocrine outpatient clinic, who completed a questionnaire, retrospectively evaluating the history of their gender transition phase. The questionnaire focused on sexual orientation and recalled time points of changes in sexual orientation in the context of transition. Participants were further asked to provide a personal concept for a potential change in sexual orientation. Results In total, 32.9% (n?=? 23) MtF reported a change in sexual orientation in contrast to 22.2% (n?=? 10) FtM transsexual persons (p?=? 0.132). Out of these patients, 39.1% (MtF) and 60% (FtM) reported a change in sexual orientation before having undergone any sex reassignment surgery. FtM that had initially been sexually oriented towards males (?=?androphilic), were significantly more likely to report on a change in sexual orientation than gynephilic, analloerotic or bisexual FtM (p ?=? 0.012). Similarly, gynephilic MtF reported a change in sexual orientation more frequently than androphilic, analloerotic or bisexual MtF transsexual persons (p ?=? 0.05). Conclusion In line with earlier reports, we reveal that a change in self-reported sexual orientation is frequent and does not solely occur in the context of particular transition events. Transsexual persons that are attracted by individuals of the opposite biological sex are more likely to change sexual orientation. Qualitative reports suggest that the individual's biography, autogynephilic and autoandrophilic sexual arousal, confusion before and after transitioning, social and self-acceptance, as well as concept of sexual orientation itself may explain this phenomenon.

    Knowledge about the effects of the neuropeptide oxytocin (OXT) on human sexual behaviors and partner interactions remains limited. Based on our previous studies, we hypothesize that OXT should be able to positively influence parameters of sexual function and couple interactions. Employing a naturalistic setting involving 29 healthy heterosexual couples (n=58 participants), we analyzed the acute effects of intranasally administered OXT (24IU) on sexual drive, arousal, orgasm and refractory aspects of sexual behavior together with partner interactions. Data were assessed by psychometric instruments (Acute Sexual Experiences Scale, Arizona Sexual Experience Scale) as well as biomarkers, such as cortisol, ?-amylase and heart rate. Intranasal OXT administration did not alter "classical" parameters of sexual function, such as sexual drive, arousal or penile erection and lubrication. However, analysis of variance and a hierarchical linear model (HLM) revealed specific effects related to the orgasmic/post-orgasmic interval as well as parameters of partner interactions. According to HLM analysis, OXT increased the intensity of orgasm, contentment after sexual intercourse and the effect of study participation. According to ANOVA analysis, these effects were more pronounced in men. Men additionally indicated higher levels of sexual satiety after sexual intercourse with OXT administration. Women felt more relaxed and subgroups indicated better abilities to share sexual desires or to empathize with their partners. The effect sizes were small to moderate. Biomarkers indicated moderate psychophysiological activation but were not affected by OXT, gender or method of contraception. Using a naturalistic setting, intranasal OXT administration in couples exerted differential effects on parameters of sexual function and partner interactions. These results warrant further investigations, including subjects with sexual and relationship problems. PMID:24503174

  5. Legitimate vs. illegitimate restrictions – a motivational and physiological approach investigating reactance processes

    Threats to our freedom are part of our daily social interactions. They are accompanied by an aversive state of motivational arousal, called reactance, which leads people to strive to reestablish their threatened freedom. This is especially the case if the threat seems to be illegitimate in nature. However, reactance theory suggests that reactance should also be aroused when people are exposed to legitimate freedom threats. In this article we first aim to show that both illegitimate and legitimate freedom threats evoke reactance. Second, we aim to extend past work on reactance by exploring the underlying process of experiencing a legitimate vs. an illegitimate restriction. In the current study (N= 57) participants were restricted in an illegitimate (unexpected and inappropriate) or legitimate (unexpected but appropriate) way, or were not restricted at all. We assessed participants’ experience of reactance, their behavioral intentions to restore their freedom, their approach motivational states, as well as their physiological arousal (heart rate). Results indicated that when restricted in an illegitimate or a legitimate way, participants indicated the same amount of reactance as well as anger. However, when looking at people’s physiological reactions, important differences between illegitimate and legitimate restrictions become apparent. Illegitimate restrictions led to an immediate arousal, whereas legitimate restrictions led to a time delayed arousal. This suggests that illegitimate restrictions lead to a sudden increase in aversive arousal. Legitimate restrictions, however, seem to be associated with a more cognitive process in which people first need to structure their thoughts and reflect upon the situation before getting into the feeling of reactance in a physiologically arousing sense. Moreover a mediation analysis could show that behavioral intentions to regain one’s freedom result in positive and negative approach motivation. In sum we propose a combined dual-process and intertwined-process model explaining people’s reactions to legitimate vs. illegitimate restrictions. PMID:26042065

    A sexual health course was offered and taught by academic staff from the Faculty of Medicine, University of Malaya during semester II of every year as a university elective course to other university students apart from medical students. The course covered a wide range of topics: adolescent sexuality, family planning and pregnancy, violence against women, alternative sexual behavior, physiology of sex, sex and the disabled, gender bias in sexuality, relationship and marriage, sexual dysfunctions, clarification of sexual attitudes and STDs and AIDS. The Sexual Knowledge and Attitude Test (SKAT-II) was used to measure students' pre- and post-course scores on sexual knowledge and attitudes. Fifty-four students who completed both the pre- and post-course tests showed a significant change in sexual knowledge and their attitudes towards sexual myths and autoeroticism. Sexual knowledge was also positively correlated with age, heterosexual relations, autoeroticism and sexual myths scores. However, sexual knowledge is negatively related to religiosity and the influence of religious beliefs on one's attitudes towards sexual matters. This study showed that the sexual health course offered does have a positive impact in increasing one's knowledge and changing one's attitudes towards sexual issues. PMID:15779575

    Neurologic disease frequently negatively affects sexual experience in multiple ways. The patient's sexual self-image, sexual function, propensity to sexual pain, and motivation to be sexually active may be impacted, as may the sexual experiences of the partner. Difficulties with mobility can limit both partners' sexual arousal and pleasure. Conditions associated with chronic pain or continence concerns add further distress. Thus sexual rehabilitation needs to address many areas. Comorbid depression is common and needs to be stabilized before definitive treatment of sexual dysfunction. Management strategies include cognitive behavioral therapy, mindfulness-based cognitive therapy, and sex therapy and, for erectile dysfunction and premature ejaculation, pharmacotherapy can be added. Benefit from all these modalities is confirmed in the general population but only pharmacologic treatment of erectile dysfunction has been studied in neurologic patients, where benefit is also seen. Testosterone is indicated only for comorbid testosterone deficit: very occasionally the neurologic condition causes secondary male hypogonadism. No androgen deficiency state has been identified in women. Results of testosterone treatment in women are conflicting: recruited women were not clearly dysfunctional and women with neurologic conditions have not been studied. Future research involving both partners using combined medical and psychologic therapy as followed in clinical practice is advocated. PMID:26003258

    2009-05-01

    This article reviews sexual function questionnaires used in urogynecology, impact of pelvic floor dysfunction (PFD) on sexual function, and impact of surgical treatment of PFD on sexual function, with a focus on the experience and publications of validated sexual function questionnaires in the urogynecologic literature. A review of the literature was performed to obtain data on sexual function and PFD focusing on those studies that utilized validated sexual function questionnaires. Validated questionnaires assure data that are reliable, quantifiable, and reproducible. Quality-of-life questionnaires, such as The King's Health Questionnaire and the Incontinence Impact Questionnaire, include a few questions addressing sexual function but really deal with the overall impact of incontinence and/or prolapse on the patient's QOL or well-being and do not focus on sexual function. General questionnaires focused on sexual function include the Female Sexual Function Index and the Sexual History Form 12, which were designed to evaluate sexual function and have undergone validation and reliability testing in a general population. General questionnaires are not condition-specific and may not be sensitive enough to detect differences due to PFD. The Pelvic Organ Prolapse Urinary Incontinence Sexual Questionnaire (PISQ) is a condition-specific questionnaire focused on sexual function for use in women with PFD and has undergone rigorous validation and reliability testing. Many recent publications examining the impact of urinary incontinence (UI), fecal incontinence, and pelvic organ prolapse (POP) using validated generalized and disease-specific questionnaires have reported poorer sexual function in women with PFD. The PISQ has been used most commonly to evaluate sexual function after surgery for PFD, with increased PISQ scores in approximately 70%. Significant improvement is noted for sexual function related to physical and partner-related factors, with no changes for orgasm, desire, or arousal after surgical repair of PFD. Studies which used generalized sexual function questionnaires mainly found no change in sexual function following surgical treatment of POP and/or UI. In summary, the use of validated questionnaires shows that PFD is associated with a negative impact on sexual functions. Surgical correction of POP and/or UI improves sexual function in approximately 70% of patients, although some studies show no change with the use of non-condition-specific questionnaires.

    This study examined how valence and arousal affect the processes linked to subsequent memory for emotional information. While undergoing an fMRI scan, participants viewed neutral pictures and emotional pictures varying by valence and arousal. After the scan, participants performed a recognition test. Subsequent memory for negative or high arousal information was associated with occipital and temporal activity, while memory for positive or low arousal information was associated with frontal activity. Regression analyses confirmed that for negative or high arousal items, temporal lobe activity was the strongest predictor of later memory whereas for positive or low arousal items, frontal activity corresponded most strongly with later memory. These results suggest that the types of encoding processes relating to memory (e.g., sensory vs. elaborative processing) can differ based on the affective qualities of emotional information.

    To aid risk assessment, management, and treatment planning it is essential to assess child sexual abusers' deviant sexual interests (DSI) and preferences (DSP) for sex with children. However, measurement of DSI/DSP is fraught with psychometric problems. In consequence, research interest has shifted to latency-based indirect measures as a measurement approach to complement self-report and physiological assessment. Utilizing the Explicit and Implicit Sexual Interest Profile (EISIP)-a multimethod approach consisting of self-report, viewing time, and Implicit Association Test (IAT) DSI/DSP measures-we replicated phallometric DSI/DSP differences between child sexual abuser subgroups in a sample of intrafamilial, extrafamilial, and child pornography offenders. DSI/DSP was associated with recidivism risk, offense-behavioral measures of pedophilic interest, and sexual fantasizing. It also negatively correlated with antisociality. Distinguishing between child sexual abuser subtypes and being related to recidivism risk, the EISIP is a useful tool for sexual offender assessments. PMID:23524323

    This article presents the development of a brief, self-report measure of female sexual function. Initial face validity testing of questionnaire items, identified by an expert panel, was followed by a study aimed at further refining the questionnaire. It was administered to 131 normal controls and 128 age-matched subjects with female sexual arousal disorder (FSAD) at five research centers. Based on clinical interpretations of a principal components analysis, a 6-domain structure was identified, which included desire, subjective arousal, lubrication, orgasm, satisfaction, and pain. Overall test-retest reliability coefficients were high for each of the individual domains (r = 0.79 to 0.86) and a high degree of internal consistency was observed (Cronbach's alpha values of 0.82 and higher) Good construct validity was demonstrated by highly significant mean difference scores between the FSAD and control groups for each of the domains (p < or = 0.001). Additionally, divergent validity with a scale of marital satisfaction was observed. These results support the reliability and psychometric (as well as clinical) validity of the Female Sexual Function Index (FSFI) in the assessment of key dimensions of female sexual function in clinical and nonclinical samples. Our findings also suggest important gender differences in the patterning of female sexual function in comparison with similar questionnaire studies in males. PMID:10782451

    This paper reports on a study of individual variability in the relationship between negative mood and sexuality in men. Part 1 involves a questionnaire survey of 919 white heterosexual men, asking what typically happens to sexual interest and response when (a) depressed and (b) anxious/stressed, using the Mood and Sexuality Questionnaire (MSQ). Trait measures of sexual inhibition and excitation, depression, anxiety, and sensation seeking were also used. Relationships between trait measures and MSQ scores were tested using multiple linear and ordinal logistic regression. Of those reporting the experience of depression, 9.4% indicated increased and 42% decreased sexual interest when depressed; for anxiety/stress, the percentages were 20.6 and 28.3%, respectively. Increase in sexual interest during negative mood states was negatively related to age and trait measures of sexual inhibition and positively related to depression proneness and sexual excitation. In Part 2, the relationship between mood and sexuality was explored qualitatively, using in-depth interviews with 43 participants from Part 1. This supported the findings in Part 1, while finding more complex relations with depression than anxiety. Sex when depressed can serve needs for intimacy and self-validation as well as sexual pleasure. Sex when anxious appears to be more simply related to the calming effect of sexual release, plus a possible "excitation transfer" effect of anxious arousal. Further research is needed to explore these relationships in clinical mood disorders. Paradoxical increases of sexual interest with negative mood may help explain high risk as well as "out of control" patterns of sexual behavior. PMID:12807294

    Arousal and valence (pleasantness) are considered primary dimensions of emotion. However, the degree to which these dimensions interact in emotional processing across sensory modalities is poorly understood. We addressed this issue by applying a crossmodal priming paradigm in which auditory primes (Romantic piano solo music) varying in arousal and/or pleasantness were sequentially paired with visual targets (IAPS pictures). In Experiment 1, the emotion spaces of 120 primes and 120 targets were explored separately in addition to the effects of musical training and gender. Thirty-two participants rated their felt pleasantness and arousal in response to primes and targets on equivalent rating scales as well as their familiarity with the stimuli. Musical training was associated with elevated familiarity ratings for high-arousing music and a trend for elevated arousal ratings, especially in response to unpleasant musical stimuli. Males reported higher arousal than females for pleasant visual stimuli. In Experiment 2, 40 nonmusicians rated their felt arousal and pleasantness in response to 20 visual targets after listening to 80 musical primes. Arousal associated with the musical primes modulated felt arousal in response to visual targets, yet no such transfer of pleasantness was observed between the two modalities. Experiment 3 sought to rule out the possibility of any order effect of the subjective ratings, and responses of 14 nonmusicians replicated results of Experiment 2. This study demonstrates the effectiveness of the crossmodal priming paradigm in basic research on musical emotions. PMID:21859191

    This study was designed to measure the level of arousal influenced by 4 different musical experiences classified by task difficulty and to examine the relationship between music-induced arousal level and personality type. Participants included 32 university students who were neither musicians nor music majors. The Eysenck Personality Questionnaire (Eysenck & Eysenck, 1975) was used to identify participants as either extravert or introvert. Participants were randomly assigned to 1 of 4 types of musical tasks: listening, singing, rhythm tapping, or keyboard playing. Arousal level was measured using the Activation-Deactivation Adjective Check List (ADACL) (Thayer, 1978) before and after the musical task. The ADACL is a self-report scale consisting of a list of 20 adjectives which describe various transitory arousal states, including energy, tiredness, tension, and calmness. Results showed no significant difference between personality types and the changes in arousal level. Result indicated a significant effect of listening on decreased tension arousal. Singing and rhythm tapping, which are regarded as having a relatively moderate task difficulty, increased energy arousal significantly and decreased tiredness arousal significantly. Participants' tiredness arousal levels also decreased significantly after keyboard playing. These findings suggest that engaging in musical experience that has a moderate level of task difficulty makes individuals more energetic and less tired. PMID:18563971

    Two experiments were conducted to test a prediction of the arousal hypothesis that increased arousal will increase intake of less palatable and healthy foods. In both experiments, arousal was manipulated by adjusting the volume of a movie (soft, loud volume) while participants consumed foods. In Experiment 1, participants ate fresh (palatable) or stale (less palatable) popcorn during a 9-minute movie played at a soft or loud volume. Experiment 2 used the same procedures with healthier foods (carrot sticks and apple slices). Partial support for the arousal hypothesis in Experiment 1 showed that participants consumed more stale but not fresh popcorn in the loud (high arousal) versus soft (low arousal) volume group. These findings suggest that low but not high palatable foods are susceptible to manipulations of arousal. Consistent with this interpretation, Experiment 2 showed that high but not low environmental arousal increased intake of the fruits and vegetables, which are typically rated as lower in palatability compared to high fat foods. These results show that high arousal in an eating-typical environment increases intake of less palatable foods, and healthy foods (i.e., fruits and vegetables). Increasing the availability of healthier foods in a loud food environment can have a positive impact on increasing intake of fruits and vegetables in that environment. PMID:24762340

    The neurophysiologic basis of near death experience (NDE) is unknown. Clinical observations suggest that REM state intrusion contributes to NDE. Support for the hypothesis follows five lines of evidence: REM intrusion during wakefulness is a frequent normal occurrence, REM intrusion underlies other clinical conditions, NDE elements can be explained by REM intrusion, cardiorespiratory afferents evoke REM intrusion, and persons with an NDE may have an arousal system predisposing to REM intrusion. To investigate a predisposition to REM intrusion, the life-time prevalence of REM intrusion was studied in 55 NDE subjects and compared with that in age/gender-matched control subjects. Sleep paralysis as well as sleep-related visual and auditory hallucinations were substantially more common in subjects with an NDE. These findings anticipate that under circumstances of peril, an NDE is more likely in those with previous REM intrusion. REM intrusion could promote subjective aspects of NDE and often associated syncope. Suppression of an activated locus ceruleus could be central to an arousal system predisposed to REM intrusion and NDE. PMID:16606911

    Recent research suggests profound sex and sexual orientation differences in sexual response. These results, however, are based on measures of genital arousal, which have potential limitations such as volunteer bias and differential measures for the sexes. The present study introduces a measure less affected by these limitations. We assessed the pupil dilation of 325 men and women of various sexual orientations to male and female erotic stimuli. Results supported hypotheses. In general, self-reported sexual orientation corresponded with pupil dilation to men and women. Among men, substantial dilation to both sexes was most common in bisexual-identified men. In contrast, among women, substantial dilation to both sexes was most common in heterosexual-identified women. Possible reasons for these differences are discussed. Because the measure of pupil dilation is less invasive than previous measures of sexual response, it allows for studying diverse age and cultural populations, usually not included in sexuality research.

Because the measure of pupil dilation is less invasive than previous measures of sexual response, it allows for studying diverse age and cultural populations, usually not included in sexuality research.

    Following up on earlier research suggesting a link between implicit affiliation motivation and progesterone (P) and implicit power motivation and testosterone [T; Schultheiss, O.C., Dargel, A., Rohde, W., 2003. Implicit motives and gonadal steroid hormones: Effects of menstrual cycle phase, oral contraceptive use, and relationship status. Horm. Behav. 43, 293-301.], we tested whether arousal of affiliation motivation increases P levels and whether arousal of power motivation increases T levels. Sixty subjects were randomly assigned to watch 30 min of either Bridges of Madison County (affiliation arousal) or The Godfather II (power arousal), or a documentary about the Amazon (control condition). Levels of P and T were assessed in saliva samples taken before (T1), immediately after (T2), and 45 min after the movie (T3). The efficacy of experimental conditions to differentially arouse motives was verified by assessment of changes in affiliation and power motive imagery expressed in imaginative stories written before and after the movie. After the movie, salivary P levels (T2 and T3) in the affiliation-arousal group were significantly higher than in the control group and marginally higher than in the power-arousal group. Subjects' postmovie T responses (T3) depended on premovie T levels: in men, higher premovie T levels predicted a greater likelihood of postmovie T increases in the Power Arousal condition but not in the other conditions, whereas in women, higher premovie T levels tended to be associated with postmovie T decreases in the Power Arousal condition but not in the other conditions. These findings suggest that aroused affiliation motivation has a specific stimulatory effect on P, whereas aroused power motivation has a specific stimulatory effect on T in men, but not in women, with high baseline T levels.

    The rapid detection and evaluation of threat is of fundamental importance for survival. Theories suggest that this evolutionary pressure has driven functional adaptations in a specialized visual pathway that evaluates threat independently of conscious awareness. This is supported by evidence that threat-relevant stimuli rendered invisible by backward masking can induce physiological fear responses and modulate spatial attention. The validity of these findings has since been questioned by research using stringent, objective measures of awareness. Here, we use a modified continuous flash suppression paradigm to ask whether threatening images induce adaptive changes in autonomic arousal, attention, or perception when presented outside of awareness. In trials where stimuli broke suppression to become visible, threatening stimuli induced a significantly larger skin conductance response than nonthreatening stimuli and attracted spatial attention over scrambled images. However, these effects were eliminated in trials where observers were unaware of the stimuli. In addition, concurrent behavioral data provided no evidence that threatening images gained prioritized access to awareness. Taken together, our data suggest that the evaluation and spatial detection of visual threat are predicted by awareness. (PsycINFO Database Record PMID:25867508

    Pedophilia is characterized by a persistent sexual attraction to prepubescent children. Treatment with anti-androgen agents, such as luteinizing hormone-releasing hormone (LH-RH) agonists, reduces testosterone levels and thereby sexual drive and arousal. We used functional magnetic resonance imaging (fMRI) to compare visual erotic stimulation pre- and on-treatment with the LH-RH agonist leuprolide acetate in the case of homosexual pedophilia.

    The current randomized study evaluated an online cognitive behavioral therapy program for female sexual problems. PursuingPleasure (PP) consisted of six online modules that included psychoeducation, sensate focus, communication exercises, cognitive exercises, and e-mail contact with a therapist. PP incorporated mindfulness training and online chat groups as well as assessed partner sexual functioning. Participants demonstrated a completion rate of 57%, with 26 women with female sexual problems and related distress completing the program compared to a wait-list control group of 31 women also experiencing sexual problems and distress. Sexual problems reported by women in both groups included difficulties with sexual desire, arousal, orgasm, and pain. The treatment group demonstrated significant improvements in all domains of female sexual response (except for sexual pain) and significant reductions in the reported frequency of sexual problems and distress. Partner sexual functioning showed positive change. Improvements in female sexual functioning and some improvements in male partner sexual functioning were maintained at three-month follow-up. Limitations and suitability of clients for this treatment approach for women who are geographically isolated, who are unable to attend face-to-face therapy, and who possess a high degree of motivation are discussed.

    This article gives a clinically oriented overview of forensically relevant forms of sexual sadism disorder and its specific relationship to sexual homicide. In sexual homicide perpetrators, peculiar patterns of sexual sadism may be a motivational pathway to kill. Sexual sadism increases the risk for reoffending in sexual offenders. Through psychotherapy and pharmacological interventions, treatment of sadistic sex offenders has to consider special characteristics that may be different from those of nonsadistic sex offenders. Many of these offenders share a combination of sexual sadistic motives and an intact self-regulation, sometimes combined with a high level of sexual preoccupation. PMID:24877708

    As noted elsewhere in this report, a central goal of the Extended Duration Orbiter Medical Project (EDOMP) was to ensure that cardiovascular and muscle function were adequate to perform an emergency egress after 16 days of spaceflight. The goals of the Regulatory Physiology component of the EDOMP were to identify and subsequently ameliorate those biochemical and nutritional factors that deplete physiological reserves or increase risk for disease, and to facilitate the development of effective muscle, exercise, and cardiovascular countermeasures. The component investigations designed to meet these goals focused on biochemical and physiological aspects of nutrition and metabolism, the risk of renal (kidney) stone formation, gastrointestinal function, and sleep in space. Investigations involved both ground-based protocols to validate proposed methods and flight studies to test those methods. Two hardware tests were also completed.

    PubMed

    Snowden, Robert J; Gray, Nicola S

    2013-04-01

    Patterns of genital arousal to sexual stimuli are somewhat different between men and women. Heterosexual males and homosexual males show clear category specific arousal that is consistent with their self-reported sexual preference. However, heterosexual women do not show this category specificity. In the present study, we attempted to measure a person's automatic appraisals of stimuli with respect to the concept of sex via the use of implicit measures (the Implicit Association Test and the priming task). In three experiments, we showed that heterosexual females did not show a sex-related category specific response in favor of male versus female stimuli. However, this lack of specificity was not due to a lack of sex-related appraisals, but by equal appraisals of both male and female stimuli. On the other hand, heterosexual men, homosexual men, and homosexual women all showed automatic sex-related appraisals of stimuli that were category specific and in line with their self-reported sexual preference. The study shows difference in the pattern of sexual interest between genders at the earliest stages of the evaluation of a stimulus. PMID:22350127

    Sexual behavior is a critical function of human procreation. Despite previous studies that investigated the neural mechanisms of basic human physiological sexual functions, the neural mechanisms that underlie individual differences in human sexual permissiveness remain unknown. We used voxel-based morphometry and a questionnaire (scale for sexual attitudes) to measure sexual permissiveness to investigate the gray matter and white matter structural correlates of sexual permissiveness. Sexual permissiveness was negatively correlated with regional gray matter density of the structures involving the right amygdala and surrounding areas, and positively correlated with regional white matter density of the white matter area that spread around the left amygdala to the hypothalamus area. There were no gender-specific relationships in the neural correlates of our findings. These findings suggest that structural variations in regions that play key roles in the basic physiological aspects of human sexuality underlie individual complex sexual attitudes in social life.

    White-footed mice, Peromyscus leucopus, were exposed to 60-Hz electric fields to study the relationship between field strength and three measures of the transient arousal response previously reported to occur with exposures at 100 kV/m. Five groups of 12 mice each were given a series of four 1-h exposures, separated by an hour, with each group exposed at one of the following field strengths: 75, 50, 35, 25, and 10 kV/m; 8 additional mice were sham-exposed with no voltage applied to the field generator. All mice were experimentally naive before the start of the experiment, and all exposures occurred during the inactive (lights-on) phase of the circadian cycle. The first exposure produced immediate increases in arousal measures, but subsequent exposures had no significant effect on any measure. These arousal responses were defined by significant increases of gross motor activity, carbon dioxide production, and oxygen consumption, and were frequently recorded with field strengths of 50 kV/m or higher. Significant arousal responses rarely occurred with exposures at lower field strengths. Responses of mice exposed at 75 and 50 kV/m were similar to previously described transient arousal responses in mice exposed to 100-kV/m electric fields. Less than half of the mice in each of the field strength groups below 50 kV/m showed arousal response based on Z (standard) scores, but the arousals of the mice that did respond were similar to those of mice exposed at higher field strengths. Polynomial regression was used to calculate the field strength producing the greatest increases for each of the arousal measures. The results show that the amplitude of the transient arousal response is related to the strength of the electric field, but different measures of arousal may have different relationships to field strength.

    2011-08-01

    Many people believe that sexual orientation (homosexuality vs. heterosexuality) is determined by education and social constraints. There are, however, a large number of studies indicating that prenatal factors have an important influence on this critical feature of human sexuality. Sexual orientation is a sexually differentiated trait (over 90% of men are attracted to women and vice versa). In animals and men, many sexually differentiated characteristics are organized during early life by sex steroids, and one can wonder whether the same mechanism also affects human sexual orientation. Two types of evidence support this notion. First, multiple sexually differentiated behavioral, physiological, or even morphological traits are significantly different in homosexual and heterosexual populations. Because some of these traits are known to be organized by prenatal steroids, including testosterone, these differences suggest that homosexual subjects were, on average, exposed to atypical endocrine conditions during development. Second, clinical conditions associated with significant endocrine changes during embryonic life often result in an increased incidence of homosexuality. It seems therefore that the prenatal endocrine environment has a significant influence on human sexual orientation but a large fraction of the variance in this behavioral characteristic remains unexplained to date. Genetic differences affecting behavior either in a direct manner or by changing embryonic hormone secretion or action may also be involved. How these biological prenatal factors interact with postnatal social factors to determine life-long sexual orientation remains to be determined. PMID:21693676

  2. Low sexual desire--is it all in her head? Pathophysiology, diagnosis, and treatment of hypoactive sexual desire disorder.

    PubMed

    Simon, James A

    2010-11-01

    Hypoactive sexual desire disorder (HSDD) is thought to be the most prevalent form of female sexual dysfunction (FSD), affecting up to 1 in 10 US women. Hypoactive sexual desire disorder is defined by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) as persistent or recurrent deficiency or absence of sexual fantasies and thoughts, and/or desire for, or receptivity to, sexual activity, which causes personal distress or interpersonal difficulties and is not caused by a medical condition or drug. This definition has recently received criticism and recommendations for changes encompass the inclusion of duration, intensity, and frequency, and the elimination of distress as a diagnostic criterion. More recently, it has been suggested that arousal and desire be combined into one disorder for the upcoming DSM-V. Causes of low desire include chronic medical conditions, medications, surgeries, and psychosocial factors, but not necessarily increased age; both pre- and postmenopausal women can have HSDD, although the frequency appears to vary by age. Sexual function requires the complex interaction of multiple neurotransmitters and hormones, both centrally and peripherally, and sexual desire is considered the result of a complex balance between inhibitory and excitatory pathways in the brain. For example, dopamine, estrogen, progesterone, and testosterone play an excitatory role, whereas serotonin and prolactin are inhibitory. Thus, decreased sexual desire could be due to a reduced level of excitatory activity, an increased level of inhibitory activity, or both. A number of validated self-report and clinician-administered instruments are available for assessing female sexual function; however, most have been used primarily in clinical research trials. The Decreased Sexual Desire Screener (DSDS) was developed for practicing clinicians who are neither trained nor specialized in FSD to assist in making an accurate diagnosis of generalized acquired HSDD. As our understanding of the pathophysiology of HSDD increases, it may become easier for physicians to identify and treat women with low sexual desire. PMID:21084789

    Sathyanarayana Rao, T. S.; Darshan, M. S.; Tandon, Abhinav

    2015-01-01

    Background: Sexuality is an important aspect of the personality of an individual and influences psychological, physical and social well-being of both men and women. It is a paradox, that in the country where ‘kamasutra’ (by Vatsyayana) took birth, there is a lack of research publications and sexuality related literature; hence the current study was conducted, to estimate the prevalence and association of sexual disorders with various socio-demographic variables, in the selected rural population. Materials and Methods: Subjects who were sexually active and fulfilled the study criteria were administered Arizona Sexual Experience Scale as screening tool for the presence of sexual problems. Those who were found to be having sexual problems were interviewed further using appropriate questionnaires. Results: 21.15% of the male subjects were diagnosed to have one (or more) sexual disorder. Prevalence of erectile dysfunction was found to be 15.77%, male hypoactive sexual desire disorder (HSDD) 2.56%; premature ejaculation was found to be prevalent in 8.76% of the male subjects. Around 14% of the female subjects were diagnosed to have female sexual disorders. Prevalence of female arousal dysfunction was found to be 6.65%, female HSDD 8.87%, female anorgasmia 5.67%, female dyspareunia 2.34% and female sexual aversion disorder was found to be prevalent in 0.37% of the female subjects. Conclusion: This study concluded that one in five males and one in seven females were suffering from one (or more) sexual disorder. Improving the training of undergraduate medical and nursing students in sexuality related issues, increasing trained individuals in sexual medicine by starting new courses, providing sex education to the general population using media and merging sexual health care with primary care, are likely to play a significant role in addressing the increasing sexual health morbidity.

    PubMed

    Gingras, Bruno; Marin, Manuela M; Fitch, W Tecumseh

    2014-01-01

    Emotions in music are conveyed by a variety of acoustic cues. Notably, the positive association between sound intensity and arousal has particular biological relevance. However, although amplitude normalization is a common procedure used to control for intensity in music psychology research, direct comparisons between emotional ratings of original and amplitude-normalized musical excerpts are lacking. In this study, 30 nonmusicians retrospectively rated the subjective arousal and pleasantness induced by 84 six-second classical music excerpts, and an additional 30 nonmusicians rated the same excerpts normalized for amplitude. Following the cue-redundancy and Brunswik lens models of acoustic communication, we hypothesized that arousal and pleasantness ratings would be similar for both versions of the excerpts, and that arousal could be predicted effectively by other acoustic cues besides intensity. Although the difference in mean arousal and pleasantness ratings between original and amplitude-normalized excerpts correlated significantly with the amplitude adjustment, ratings for both sets of excerpts were highly correlated and shared a similar range of values, thus validating the use of amplitude normalization in music emotion research. Two acoustic parameters, spectral flux and spectral entropy, accounted for 65% of the variance in arousal ratings for both sets, indicating that spectral features can effectively predict arousal. Additionally, we confirmed that amplitude-normalized excerpts were adequately matched for loudness. Overall, the results corroborate our hypotheses and support the cue-redundancy and Brunswik lens models. PMID:24215647

    The influence, if any, of emotional arousal on memory is a controversial topic in the literature. Much of the research on memory for emotionally arousing events has focused on a few specific issues (e.g., differences in types of details recalled in emotionally arousing and neutral events; increasing ecological validity). Although gaining more recent attention, a neglected area in the literature has been memory for instances of repeated, emotionally arousing events. This issue has important implications for understanding children's ability to recall events in a forensic setting. We review existing findings on memory for emotionally arousing events in general and particularly in children, children's memory for events that occur repeatedly, and then discuss the scarce research on repeated emotionally arousing events and the need for further research in this area. We conclude that although it is clear that children are capable of accurately reporting arousing and repeated experiences, it is also apparent that circumstances both within and outside the control of investigative interviewers influence this ability.

    Attention is drawn to emotionally salient stimuli. The present study investigates processing of emotionally salient regions during free viewing of emotional scenes that were categorized according to the two-dimensional model comprising of valence (unpleasant, pleasant) and arousal (high, low). Recent studies have reported interactions between these dimensions, indicative of stimulus-evoked approach or withdrawal tendencies. We addressed the valence and arousal effects when emotional items were embedded in complex real-world scenes by analyzing both eye movement behavior and eye-fixation-related potentials (EFRPs) time-locked to the critical event of fixating the emotionally salient items for the first time. Both data sets showed an interaction between the valence and arousal dimensions. First, the fixation rates and gaze durations on emotionally salient regions were enhanced for unpleasant versus pleasant images in the high arousal condition. In the low arousal condition, both measures were enhanced for pleasant versus unpleasant images. Second, the EFRP results at 140-170 ms [P2] over the central site showed stronger responses for high versus low arousing images in the unpleasant condition. In addition, the parietal LPP responses at 400-500 ms post-fixation were enhanced for stimuli reflecting congruent stimulus dimensions, that is, stronger responses for high versus low arousing images in the unpleasant condition and stronger responses for low versus high arousing images in the pleasant condition. The present findings support the interactive two-dimensional approach, according to which the integration of valence and arousal recruits brain regions associated with action tendencies of approach or withdrawal.

    Background Emotion can either facilitate or impair memory, depending on what, when and how memory is tested and whether the paradigm at hand is administered as a working memory (WM) or a long-term memory (LTM) task. Whereas emotionally arousing single stimuli are more likely to be remembered, memory for the relationship between two or more component parts (i.e., relational memory) appears to be worse in the presence of emotional stimuli, at least in some relational memory tasks. The current study investigated the effects of both valence (neutral vs. positive vs. negative) and arousal (low vs. high) in an inter-item WM binding and LTM task. Methodology/Principal Findings A five-pair delayed-match-to-sample (WM) task was administered. In each trial, study pairs consisted of one neutral picture and a second picture of which the emotional qualities (valence and arousal levels) were manipulated. These pairs had to be remembered across a delay interval of 10 seconds. This was followed by a probe phase in which five pairs were tested. After completion of this task, an unexpected single item LTM task as well as an LTM task for the pairs was assessed. As expected, emotional arousal impaired WM processing. This was reflected in lower accuracy for pairs consisting of high-arousal pictures compared to pairs with low-arousal pictures. A similar effect was found for the associative LTM task. However, the arousal effect was modulated by affective valence for the WM but not the LTM task; pairs with low-arousal negative pictures were not processed as well in the WM task. No significant differences were found for the single-item LTM task. Conclusions/Significance The present study provides additional evidence that processes during initial perception/encoding and post-encoding processes, the time interval between study and test and the interaction between valence and arousal might modulate the effects of “emotion” on associative memory.

  11. Treatment of sexual offenders with psychopathic traits: recent research developments and clinical implications.

    2008-07-01

    This article provides a review of recent literature related to the treatment of psychopathy in forensic settings, with particular focus on studies with sexual offenders. The lack of empirical support for the position that psychopaths are untreatable is noted, and data suggesting optimism is discussed. Research demonstrating an interaction between psychopathy and substance abuse and between psychopathy and sexual deviance is also presented. Both substance abuse disorders and inappropriate arousal are frequently encountered in high-risk groups of sexual offenders. These topics are of relevance, in that the question of whether treatment is beneficial with high-risk sexual offenders, including those who are psychopathic, cannot be answered unless groups presenting with typical concurrent disorders (paraphilias, substance abuse, dependence) are discussed. It is argued that, although the evidence is still preliminary, there is reason for optimism with reference to whether psychopathic sexual offenders are responsive to treatment, including offenders presenting with concurrent disorders.

    Devotism, defined as sexual attraction toward disabilities, has not undergone extensive study. To verify whether devotees have characteristics suggestive of a paraphilic behavior, an ad hoc internet questionnaire was developed to study a population of 209 subjects enrolled from online devotee communities. With respect to the sexual preference, we observe a first population comprising subjects sexually attracted by disability per se and considers it as an erotic object. In the absence of disability, this group is also unable to become sexually aroused and experiences discomfort due to their condition. The second subpopulation comprises subjects attracted by specific characteristics of people with disabilities such as adaptability, fortitude, courage and ability to overcome obstacles. This group experiences low levels of discomfort for their sexual preference. Further studies will be necessary to confirm these data. PMID:24048013

    Effort magnitude is commonly thought to reflect motivation, but little is known about the influence of emotional factors. Here, we manipulated the emotional state of subjects, via the presentation of pictures, before they exerted physical effort to win money. After highly arousing pictures, subjects produced more force and reported lower effort sensation, regardless of monetary incentives. Functional neuroimaging revealed that emotional arousal, as indexed by postscan ratings, specifically correlated with bilateral activity in the ventrolateral prefrontal cortex. We suggest that this region, by driving the motor cortex, constitutes a brain pathway that allows emotional arousal to facilitate physical effort. PMID:19641108

    This study explored factors (gender, age, relationship status, symptomatology) associated with the sexual well-being of 141 (56 men and 85 women) adults with high-functioning autism and Asperger syndrome (HFA/AS) living in the community. Participants completed an online survey consisting of a measure of autistic symptoms as well as measures of dyadic and solitary sexual well-being. Canonical correlation analyses showed that participants who were currently in a romantic relationship reported more frequent dyadic affectionate and genital activity and greater sexual assertiveness and sexual satisfaction, pointing to the importance of context in an active sex life. After controlling for the first variate, men and individuals with less autism symptomatology, particularly in the social and communication domains, generally reported significantly greater dyadic sexual well-being, including greater sexual satisfaction, assertiveness, arousability, and desire and lower sexual anxiety and fewer sexual problems. Men also reported better solitary sexual well-being, including more sexual thoughts, more sexual desire, and more frequent solitary sexual activity; however, they had lower sexual knowledge. These results highlight the importance for research and sexuality education with individuals with HFA/AS to conceptualize sexual well-being as a multidimensional construct consisting of both dyadic and solitary aspects.

  18. Sexual inadequacy in the male

    PubMed Central

    Bancroft, John

    1971-01-01

    The adequacy of sexual functioning in the male depends on a complex interaction between psychological, hormonal and neurophysiological factors. Disturbance of any one of these factors may lead to sexual inadequacy. In the majority of cases no gross abnormality is found but the absence of gross hormonal or neurophysiological abnormality does not necessarily imply a purely psychological cause. Individual variations in the pattern of response of the autonomic nervous system or in the ability to learn control of autonomic responses such as erection or ejaculation may be sufficient to account for some cases of inadequacy and in others may increase the susceptibility to psychological factors. Further research is required to clarify these undoubtedly important psychophysiological relationships. Treatment has been most successful when it has taken into account both psychological and physiological factors. The advances made by Masters & Johnson (1970) in this area have partly depended on their earlier physiological and anatomical studies of sexual response (Masters & Johnson, 1966). It may be that in some cases the use of anxiety-reducing drugs or androgens will be all that is required but further work is required to identify such cases. The placebo effects of such preparations should not be overlooked particularly as many cases of sexual inadequacy are based on lack of confidence or ignorance and require little more than good advice or reassurance. Considerable advances in our understanding of these problems have been made in the past 20 years and techniques of endocrine, physiological and behavioural assessment are now available which should enable further progress to be made in the near future.

  19. Diabetes and sexual dysfunction: current perspectives

    PubMed Central

    Maiorino, Maria Ida; Bellastella, Giuseppe; Esposito, Katherine

    2014-01-01

    Diabetes mellitus is one of the most common chronic diseases in nearly all countries. It has been associated with sexual dysfunction, both in males and in females. Diabetes is an established risk factor for sexual dysfunction in men, as a threefold increased risk of erectile dysfunction was documented in diabetic men, as compared with nondiabetic men. Among women, evidence regarding the association between diabetes and sexual dysfunction are less conclusive, although most studies have reported a higher prevalence of female sexual dysfunction in diabetic women as compared with nondiabetic women. Female sexual function appears to be more related to social and psychological components than to the physiological consequence of diabetes. Hyperglycemia, which is a main determinant of vascular and microvascular diabetic complications, may participate in the pathogenetic mechanisms of sexual dysfunction in diabetes. Moreover, diabetic people may present several clinical conditions, including hypertension, overweight and obesity, metabolic syndrome, cigarette smoking, and atherogenic dyslipidemia, which are themselves risk factors for sexual dysfunction, both in men and in women. The adoption of healthy lifestyles may reduce insulin resistance, endothelial dysfunction, and oxidative stress – all of which are desirable achievements in diabetic patients. Improved well-being may further contribute to reduce and prevent sexual dysfunction in both sexes. PMID:24623985

    We examined the seasonal changes of the cecal microbiota of captive arctic ground squirrels (Urocitellus parryii) by measuring microbial diversity and composition, total bacterial density and viability, and short-chain fatty acid concentrations at four sample periods (summer, torpor, interbout arousal, and posthibernation). Abundance of Firmicutes was lower, whereas abundances of Bacteroidetes, Verrucomicrobia, and Proteobacteria were higher during torpor and interbout arousal than in summer. Bacterial densities and percentages of live bacteria were significantly higher in summer than during torpor and interbout arousal. Likewise, total short-chain fatty acid concentrations were significantly greater during summer than during torpor and interbout arousal. Concentrations of individual short-chain fatty acids varied across sample periods, with butyrate concentrations higher and acetate concentrations lower during summer than at all other sample periods. Characteristics of the gut community posthibernation were more similar to those during torpor and interbout arousal than to those during summer. However, higher abundances of the genera Bacteroides and Akkermansia occurred during posthibernation than during interbout arousal and torpor. Collectively, our results clearly demonstrate that seasonal changes in physiology associated with hibernation and activity affect the gut microbial community in the arctic ground squirrel. Importantly, similarities between the gut microbiota of arctic ground squirrels and thirteen-lined ground squirrels suggest the potential for a core microbiota during hibernation. PMID:25002417

    A number of studies have reported the association of sexual problems with ankylosing spondylitis (AS); however, the results have been conflicting. The present study aimed to investigate the impact of AS on sexual function. To develop a more comprehensive understanding of sexual function in patients with AS, a systematic review and meta-analysis of the literature up to 2013 was conducted. Studies that assessed the impact of AS on sexual function by adopting the International Index of Erectile Function or the Female Sexual Function Index (FSFI) scoring system were included. Statistical analysis was performed using Review Manager statistical software (version 5.2). The weighted mean differences were calculated by employing a fixed or random effects model. A total of 484 cases from five studies were identified as being well-documented and included in the meta-analysis. Compared with healthy controls, male patients with AS have a significant reduction in sexual function scores of erectile function (?3.07), orgasmic function (?1.17), sexual drive (?0.72) and intercourse satisfaction (?1.89). Female patients with AS have a lower FSFI score in domains of desire (?0.34) and arousal (?0.87). In conclusion, AS has a certain impact on the sexual function of male patients. AS appears to have a greater influence on the sexual function of males compared with that of females. However, the mechanism by which AS affects sexual function requires further evaluation by further studies of a larger population of patients. PMID:25780459

    The purpose of this investigation was to compare the neurotoxic potential of trimethylbenzene (TMB) isomers (the solvents) with that of benzene derivatives with a smaller number of methyl groups (toluene). The experiments were performed on WAG/Rij rats with EEG recording electrodes implanted in the fronto-parietal cortex. The solvents, toluene or TMB isomers: 1,3,5-TMB (mesitylene), 1,2,3-TMB (hemimellitene) or 1,2,4-TMB (pseudocumene), were diluted with olive oil and administered intragastrically via gavage at an acute dose of 0.002, 0.008, or 0.032 mol/kg. The electrocortical activity was recorded for 20 min before, and for 60 min after the solvent administration. The electrocorticograms were analysed with respect to the number and duration of the high-voltage spindles (HVS), a form of activity sensitive to the arousal level. In case of each solvent the observed effect--inhibition of the HVS activity--was dose-related. However, the effect produced by TMB isomers was in each case less pronounced than that of toluene. Among TMBs, pseudocumene displayed the least significant effect, and the efficacy of two other TMB isomers was similar. PMID:10846847

    The purpose of this study was to explore parent-child sexual communication by investigating the impact of direct and indirect parental messages on the sexual attitudes and sexual satisfaction of young adults. A survey research design was used to obtain data from undergraduate students attending a large Southern university. The findings indicate that both direct and indirect parental sexual messages are negative and restrictive and have a differential impact on sexual satisfaction and sexual attitudes. While sexual satisfaction was positive, sexual attitudes were found to be problematic, especially among females. Suggestions are given for approaches that family life educators and parents may use in order to recycle previous sexual messages. PMID:6631981

  11. Glutamatergic Signaling from the Parabrachial Nucleus Plays a Critical Role in Hypercapnic Arousal

    The mechanisms of arousal from apneas during sleep in patients suffering from obstructive sleep apnea (OSA) are not well understood. However, respiratory chemosensory pathways converge on the parabrachial nucleus (PB), which sends glutamatergic projections to a variety of forebrain structures critical to arousal including the basal forebrain, lateral hypothalamus, midline thalamus, and cerebral cortex. We tested the role of glutamatergic signaling in this pathway by developing an animal model for repetitive CO2 arousals (RCA) and investigating the effect of deleting the gene for the vesicular glutamate transporter 2 (Vglut2) from neurons in the PB. We used mice with lox P sequences flanking exon2 of the Vglut2 gene, in which adeno-associated viral vectors containing genes encoding Cre recombinase and green fluorescent protein were microinjected into the PB to permanently and selectively disrupt Vglut2 expression while labeling the affected neurons. We recorded sleep in these mice and then investigated the arousals during RCA. Vglut2 deletions that included the external lateral and lateral crescent subdivisions of the lateral PB more than doubled the latency to arousal and resulted in failure to arouse by 30 s in over 30% of trials. By contrast, deletions that involved the medial PB subdivision had minimal effects on arousal during hypercapnia but instead increased NREM sleep by about 43% during the dark period, and increased delta power in the EEG during NREM sleep by about 50%. Our results suggest that glutamatergic neurons in the lateral PB are necessary for arousals from sleep in response to CO2, while medial PB glutamatergic neurons play an important role in promoting spontaneous waking.

    This document provides information on issues related to sexual assault in the US. The specific topics briefly discussed are incidence, psychological impact, assault assessment kits, medical evaluation, legal concerns, counseling, follow-up, and special circumstances. It is stated that a woman who is sexually assaulted would experience intense anxiety, anger or fear, and rape-trauma syndrome. The physician evaluating the victim should be aware of the state statutory requirements, which may involve the use of kits for gathering evidence. Informed consent from the victim and meticulous physical examination of the entire body should be performed with photographs and drawings made in the injured areas. In counseling, the physician should talk with the patient concerning the degree of the injury and the probability of infection or pregnancy. There is a need for patients to be reevaluated concerning her medical and psychological status. PMID:12295376

    2008-01-01

    Objective To assess affective event-related brain potentials (ERPs) using visual pictures that were highly distinct on arousal level/valence category ratings and a response task. Methods Images from the International Affective Pictures System (IAPS) were selected to obtain distinct affective arousal (low, high) and valence (negative, positive) rating levels. The pictures were used as target stimuli in an oddball paradigm, with a visual pattern as the standard stimulus. Participants were instructed to press a button whenever a picture occurred and to ignore the standard. Task performance and response time did not differ across conditions. Results High-arousal compared to low-arousal stimuli produced larger amplitudes for the N2, P3, early slow wave, and late slow wave components. Valence amplitude effects were weak overall and originated primarily from the later waveform components and interactions with electrode position. Gender differences were negligible. Conclusion The findings suggest that arousal level is the primary determinant of affective oddball processing, and valence minimally influences ERP amplitude. Significance Affective processing engages selective attentional mechanisms that are primarily sensitive to the arousal properties of emotional stimuli. The application and nature of task demands are important considerations for interpreting these effects. PMID:18783987

    Many breast cancer survivors report a loss of sexual desire and arousability, consonant with the new DSM-V category of female sexual interest/arousal disorder. The cause of decreased sexual desire and pleasure after treatment for cancer is unknown. One possibility is that cancer, or treatment for cancer, damages brain circuits that are involved in reward-seeking. To test the hypothesis that brain reward systems are involved in decreased sexual desire in breast cancer survivors, we used functional magnetic resonance imaging (fMRI) to compare brain responses to erotica and other emotional stimuli in two groups of women previously treated for breast cancer with chemotherapy: those who were distressed about a perceived loss of sexual desire and those who may have had low desire, but were not distressed about it. Women distressed about their desire had reduced brain responses to erotica in the anterior cingulate and dorsolateral prefrontal cortex, which are part of the brain reward system. This study is the first to demonstrate, in cancer survivors, that problems with sexual desire/arousability are associated with blunted brain responses to erotica in reward systems. Future research is necessary to determine whether brain responses differ as a result of chemotherapy, hormone therapy, and menopausal status. This may contribute to the development of new, evidence-based interventions for one of the most prevalent and enduring side effects of cancer treatment. PMID:23955492

  18. Individual Differences in Nucleus Accumbens Activity to Food and Sexual Images Predict Weight Gain and Sexual Behavior

    2012-01-01

    Failures of self-regulation are common, leading to many of the most vexing problems facing contemporary society, from overeating and obesity to impulsive sexual behavior and HIV/AIDS. One reason that people may be prone to engaging in unwanted behaviors is because of heightened sensitivity to cues related to those behaviors; people may overeat because of hyper responsiveness to food cues, addicts may relapse following exposure to their drug of choice, and some people might engage in impulsive sexual activity because they are easily aroused by erotic stimuli. An open question is the extent to which individual differences in neural cue reactivity relate to actual behavioral outcomes. Here we show that individual differences in human reward-related brain activity in the nucleus accumbens to food and sexual images predict subsequent weight gain and sexual activity six months later. These findings suggest that heightened reward responsivity in the brain to food and sexual cues is associated with indulgence in overeating and sexual activity, respectively, and provide evidence for a common neural mechanism associated with appetitive behaviors.

    This prospective study described the trajectory of sexual well-being from before hematopoietic cell transplantation (HCT) to 3 years after in 131 allogeneic and 146 autologous HCT recipients using Derogatis Interview for Sexual Function and Derogatis Global Sexual Satisfaction Index. Sixty-one percent of men and 37% of women were sexually active pre-HCT; the prevalence declined to 51% (P = .01) in men and increased to 48% (P = .02) in women at 3 years post-HCT. After HCT, sexual satisfaction declined in both sexes (P < .001). All sexual function domains were worse in women compared with men (P ? .001). Orgasm (P = .002) and drive/relationship (P < .001) declined in men, but sexual cognition/fantasy (P = .01) and sexual behavior/experience (P = .01) improved in women. Older age negatively impacted sexual function post-HCT in both sexes (P < .01). Chronic graft-versus-host disease was associated with lower sexual cognition/fantasy (P = .003) and orgasm (P = .006) in men and sexual arousal (P = .05) and sexual satisfaction (P = .005) in women. All male sexual function domains declined after total body irradiation (P < .05). This study identifies vulnerable subpopulations that could benefit from interventional strategies to improve sexual well-being. PMID:24159171

    As adolescents progress through puberty, many biological changes occur and, for young women, this includes the onset of menses and the capability for reproduction. During this time, sexual identity is developed and expressions of sexuality become more frequent. Adolescent women engage in a variety of sexual behaviours, both non-coital and coital. As teens begin dating relationships, they are at risk
