    ABSTRACT: Vaginal vasocongestion and lubrication serve to prepare the vaginal lumen for sexual activity. Lubrication is important for sexual functioning and difficulties with lubrication are one of the most commonly reported symptoms of sexual dysfunction. Few studies have empirically examined how vasocongestion and lubrication relate to one another and there are currently no well-established measures of lubrication. In this study, we designed and tested a simple method to assess lubrication at the vaginal introitus in 19 healthy women, using litmus test strips. We examined the relationship between lubrication and vaginal vasocongestion (measured with a photoplethysmograph) when elicited by audiovisual sexual stimuli (male–female sexual interactions). Lubrication was elicited by the sexual stimuli and was strongly correlated with reports of sexual arousal. Unexpectedly, lubrication was not correlated with vasocongestion, even though the latter was also elicited by the sexual stimuli. We discuss the implications of these findings for informing our understanding of the female sexual response and the potential clinical and scientific utility of this new measure.

    ABSTRACT: Müller et al. (2014) recently published a chart review study of 43 men diagnosed with pedophilia (DSM-III, IV, or IV-TR) and phallometrically assessed for pedophilic interest on two occasions. Phallometry involves the measurement of erections while examinees are exposed to a variety of sexual stimuli in the laboratory. All 43 men showed larger penile responses to child stimuli than to adult stimuli on the first assessment (as a requirement for inclusion in the study) and 21 of them showed the reverse pattern on the second assessment occurring at least 6 months later (on average, 50 months later). Müller et al. concluded that the results provided “an important challenge to the belief that the sexual interests in men with pedophilia cannot change toward interest in adults” (p. 1228). Fedoroff, the corresponding author of the article, recently asserted in a radio interview that “In treatment, people can not only lose recurrent, intense sexually arousing fantasies involving children, but c ...

    ABSTRACT: Little research has been conducted to examine paraphilic sexual interests in nonclinical samples. The little that exists suggests that atypical sexual interests are more common in men than in women, but the reasons for this difference are unknown. In this study, we explored the prevalence of paraphilic interests in a nonclinical sample of men and women. We expected that men would report greater arousal (or less repulsion) toward various paraphilic acts than women. We also examined putative correlates of paraphilias in an attempt to explain the sex difference. In all, 305 men and 710 women completed an online survey assessing sexual experiences, sexual interests, as well as indicators of neurodevelopmental stress, sex drive, mating effort, impulsivity, masculinity/femininity, and socially desirable responding. As expected, significant sex differences were found, with men reporting significantly less repulsion (or more arousal) to the majority of paraphilic acts than women. Using mediation analysis, sex drive was the only correlate to significantly and fully mediate the sex difference in paraphilic interests. In other words, sex drive fully accounted for the sex difference in paraphilic interests. The implications of these findings for understanding the etiology of atypical sexual interests are discussed.

    ABSTRACT: Sexual concordance refers to the association between physiological and self-reported sexual arousal. Women typically exhibit lower sexual concordance scores than men. There is also a sex difference in interoception-awareness of (nonsexual) physiological states or responses-such that women, compared with men, tend to be less aware of and less accurate at detecting changes in their physiological responses. Women with anxiety problems tend to have better interoceptive abilities than nonanxious women. To investigate whether women's lower sexual concordance is associated with interoception using a sample likely to show high variation in interoceptive abilities. Sixteen anxious and 15 nonanxious women were presented with twelve 90 seconds sexual and nonsexual film clips while their genital response, heart rate, and respiration rate were measured. A heartbeat mental tracking task was also employed. Genital response was measured with a vaginal photoplethysmograph. Heart rate was measured with an electrocardiogram and respiration rate with a thermistor. Participants estimated their physiological responses after each film. A mental tracking task was also used to assess participants' awareness of heart rate. Within-subject correlations were computed for each physiological/self-reported response combination. Overall, sexual concordance (i.e., the correlation between genital responses and perceptions of genital response) was not significantly associated with heart rate awareness or respiration rate awareness. Anxious women did not exhibit significantly higher sexual concordance or heart rate awareness than nonanxious women; the nonanxious women actually exhibited higher respiration rate awareness. The results suggest that sexual concordance may be a distinct phenomenon from interoception and in need of its own explanation. Suschinsky KD and Lalumière ML.

    ABSTRACT: Studies investigating men and women separately suggest a sex difference in the habituation of genital responses to sexual stimuli: Men’s responses habituate readily whereas women’s responses appear more resistant. These studies also demonstrate that attention is positively correlated with habituation effects when they occur. The preparation hypothesis asserts that women’s genital responses occur automatically in the presence of sexual cues to protect them from injuries that may occur as a result of penetration. It follows that women may not habituate as much as men because the costs of not responding to sexual cues are likely higher for women than they are for men. In a recent study we found similar and pronounced habituation effects for genital responses and self-reported attention in men and in women. The aims of the current study were to examine whether habituation can be elicited when attention is maintained and if a sex difference would be observed. Thirty-six men and women were presented with 14 audiovisual stimuli following a within-subjects habituation design. Genital responses were measured using circumferential phallometry and vaginal photoplethysmography. Poststimulus ratings of sexual arousal and attention were recorded. Results showed habituation of genital but not subjective sexual responses in both sexes. Participants reported a high degree of attention across habituation trials, but controlling for changes in attention eliminated habituation effects for genital responses. The role of attention in sexual responses and the implications of our findings for the preparation hypothesis are discussed. (PsycINFO Database Record (c) 2013 APA, all rights reserved)

    ABSTRACT: Given that social messages encourage women to inhibit sexual responses, and that measures of women’s genital arousal are not always consistent with self-reported sexual arousal, we evaluated the relationship between impression management (IM) and 3 methods of assessing self-reported sexual arousal: continuously rated arousal, pre- and poststimulus discrete ratings of arousal, and change in arousal. In Study 1, women (N = 39) reported their sexual arousal continuously throughout neutral and erotic audio narratives and following each stimulus using discrete scales. In Study 2, women (N = 40) reported their sexual arousal prior to, continuously throughout, and following neutral and erotic films. Across studies, discrete measures of sexual arousal (pre- and poststimulus) were significantly negatively correlated with total IM scores (assessed using the IM subscale of the Balanced Inventory of Desirable Responding [BIDR-6]), whereas continuously reported sexual arousal was not significantly associated with IM. In Study 2, change in arousal reported before and after each stimulus was not consistently related to IM, though IM was significantly negatively correlated with change in desire to masturbate. We recommend that researchers assess self-reported sexual arousal using continuous measures or change scores, rather than discrete measures, and consider controlling for IM.

    ABSTRACT: In a recent study, we found a negative association between psychopathy and violence against genetic relatives. We interpreted this result as a form of nepotism and argued that it failed to support the hypothesis that psychopathy is a mental disorder, suggesting instead that it supports the hypothesis that psychopathy is an evolved life history strategy. This interpretation and subsequent arguments have been challenged in a number of ways. Here, we identify several misunderstandings regarding the harmful dysfunction definition of mental disorder as it applies to psychopathy and regarding the meaning of nepotism. Furthermore, we examine the evidence provided by our critics that psychopathy is associated with other disorders, and we offer a comment on their alternative model of psychopathy. We conclude that there remains little evidence that psychopathy is the product of dysfunctional mechanisms.

    ABSTRACT: Introduction.  Laboratory studies have revealed two well-replicated sex differences in sexual arousal patterns: category specificity and sexual concordance. Men's genital responses are dependent on specific sexual cues and are concordant with subjective reports of arousal. Women's genital responses are much less dependent on specific sexual cues and are much less concordant with their subjective reports. The preparation hypothesis provides a functional explanation for these sex differences and posits that women's genital responses are not tied to sexual preferences but rather occur automatically in the presence of any sexual cue to protect the genital tissues from injuries incurred through sexual activity. This hypothesis leads to the expectation that women's genital responses may not habituate as quickly or as completely as men's. Aim.  To determine whether there is a sex difference in the habituation of genital responses and to further test the preparation hypothesis of women's genital responses. Methods.  Twenty men and 20 women had their genital responses measured while they were exposed to nine consecutive presentations of the same erotic film clip (habituation), followed by two presentations of different erotic film clips (novelty), and followed by two presentations of the original erotic film clip (dishabituation). Main Outcome Measures.  Genital responses were measured continuously using penile strain gauges (assessing penile circumference) and vaginal probes (assessing vaginal pulse amplitude). Participants reported subjective sexual arousal, perceived genital arousal, and attention after each film clip presentation. Results.  Men and women displayed very similar patterns of genital responses, consistent with habituation and novelty effects. Effects of habituation and novelty were eliminated once subjective reports of attention were covaried. Conclusion.  Contrary to the prediction from the preparation hypothesis of women's genital responses, men's and women's responses showed similar patterns of habituation upon repeated exposure. Future research should attempt to maintain participants' attention in order to further test the preparation hypothesis. Dawson SJ, Suschinsky KD, and Lalumière ML.

    ABSTRACT: Risk-sensitivity theory predicts that organisms are more likely to take risks when they are unlikely to achieve their goals through safer, low-risk means. Those who are competitively disadvantaged are less likely to succeed in social competition and should consequently show elevated risk-taking. We experimentally tested this hypothesis by exposing participants to cues of relative competitive disadvantage or relative competitive advantage via feedback from a purported intelligence test. Participants then made a number of high-risk or low-risk economic decisions (Experiment 1). Experiment 2 built on this design by either maintaining or ameliorating cues of relative competitive (dis)advantage. Results indicate that cues of relative competitive disadvantage led to increased risk-taking, and that risk-taking can be reduced when cues of disadvantage are ameliorated. Since risk-taking tends to generalize across domains, these results can potentially apply to a number of problematic risky behaviors.

    ABSTRACT: Psychopaths routinely disregard social norms by engaging in selfish, antisocial, often violent behavior. Commonly characterized as mentally disordered, recent evidence suggests that psychopaths are executing a well-functioning, if unscrupulous strategy that historically increased reproductive success at the expense of others. Natural selection ought to have favored strategies that spared close kin from harm, however, because actions affecting the fitness of genetic relatives contribute to an individual's inclusive fitness. Conversely, there is evidence that mental disorders can disrupt psychological mechanisms designed to protect relatives. Thus, mental disorder and adaptation accounts of psychopathy generate opposing hypotheses: psychopathy should be associated with an increase in the victimization of kin in the former account but not in the latter. Contrary to the mental disorder hypothesis, we show here in a sample of 289 violent offenders that variation in psychopathy predicts a decrease in the genetic relatedness of victims to offenders; that is, psychopathy predicts an increased likelihood of harming non-relatives. Because nepotistic inhibition in violence may be caused by dispersal or kin discrimination, we examined the effects of psychopathy on (1) the dispersal of offenders and their kin and (2) sexual assault frequency (as a window on kin discrimination). Although psychopathy was negatively associated with coresidence with kin and positively associated with the commission of sexual assault, it remained negatively associated with the genetic relatedness of victims to offenders after removing cases of offenders who had coresided with kin and cases of sexual assault from the analyses. These results stand in contrast to models positing psychopathy as a pathology, and provide support for the hypothesis that psychopathy reflects an evolutionary strategy largely favoring the exploitation of non-relatives.

    ABSTRACT: Published typologies of sexual homicide lack theoretical grounding and empirical support. They also conceptualize the phenomenon of sexual homicide as somewhat discrete, though offenders are not typically specialists. Here, we propose a model that situates the phenomenon of sexual killing into broader categories of antisocial behavior, positing three types of perpetrators of serial sexual homicides: competitively disadvantaged, psychopathic, and sadistic offenders. Using biographical data of 82 serial sexual homicide offenders, we tested our model as well as the influential organized/disorganized model. Principal components analysis produced five components consisting of offender and offense characteristics, and cluster analysis revealed three distinct groups of perpetrators (sadistic offenders, competitively disadvantaged offenders, and slashers), as well as a fourth, heterogeneous group; this cluster solution, however, may be unstable. In summary, there is only mixed support for either model.

    ABSTRACT: On average, rapists show greater relative genital responses to rape stories than do nonrapists in the laboratory. It has been suggested that this robust group difference is explained by the fact that many rapists are sexually sadistic. It is not clear, however, what the critical cues underlying rapists' genital responses are, because rape stories used in previous research include a mix of sadistic cues of violence and victim injury as well as cues of victim resistance and nonconsent. The present study was conducted to identify the critical cues producing self-identified sadists' sexual responses, and thereby to test sexual sadism as an explanation of rapists' arousal pattern. The present study was also conducted to develop a new phallometric test for sexual sadism for research and clinical applications, given evidence of poor diagnostic reliability and validity. Eighteen self-identified male sadists, 22 men with some sadistic interests who did not meet all of our sadist criteria, and 23 nonsadists (all recruited from the community) were compared in their genital and subjective responses to a new set of stories that disentangle violence/injury cues from resistance/nonconsent cues. The three groups differed in both their genital and subjective responses: using indices of relative responding, sadists responded significantly more to cues of violence/injury than nonsadists and men with some sadistic interests. The group difference for cues of nonconsent was not significant. The results suggest that sexual sadism primarily involves arousal to violence/injury in a sexual context rather than resistance/nonconsent.

    ABSTRACT: The evolution of spite entails actors imposing costs on 'negative' relatives: those who are less likely than chance to share the actor's alleles and therefore more likely to bear rival alleles. Yet, despite a considerable body of research confirming that organisms can recognize positive relatives, little research has shown that organisms can recognize negative relatives. Here, we extend previous work on human phenotype matching by introducing a cue to negative relatedness: negative self-resembling faces, which differ from an average face in the opposite direction to the way an individual's own face differs from the average. Participants made trustworthiness and attractiveness judgements of pairs of opposite-sex positive and negative self-resembling faces. Analyses revealed opposing effects of positive and negative self-resembling faces on trustworthiness and attractiveness judgements. This is the first clear evidence that humans are sensitive to negative relatedness cues, and suggests the potential for the adaptive allocation of spiteful behaviour.

    ABSTRACT: In phallometric research, rapists have a unique pattern of erectile responses to stimuli depicting sexual activities involving coercion and violence. In this study, we attempted to determine the cues that control rapists' erectile responses to rape stories in the laboratory. A total of 12 rapists and 14 non-rapists were exposed to recorded audio scenarios that systematically varied with regard to the presence or absence of three orthogonally varied elements: sexual activity and nudity, violence and injury, and expression of non-consent. As expected from prior research, an index computed by subtracting participants' greatest mean responses to stories describing mutually consenting sexual activity from their greatest mean responses to stories describing rape was much higher among rapists than non-rapists. Both groups showed larger responses when stories involved sexual activity and nudity, but neither group exhibited a preference for cues of violence and serious injury, or for cues of non-consent. The element that produced the larger group difference, however, was the presence or absence of active consent. The results indicated that a sexual interest in (or indifference to) non-consent is at least as central to accounting for the unique sexual orientation of rapists as is sexual responding to violence and injury.

    ABSTRACT: Recent research has revealed that many aspects of female sexuality change across the menstrual cycle. In this study, we examined changes in sexual fantasies and visual sexual interests across the menstrual cycle. A total of 27 single, heterosexual women (M age=21.5 years) not using hormonal contraceptives answered questions on a web-based diary every day for 30 days about their sexual fantasies and behaviors. Twenty-two of them also completed a viewing time task during three different menstrual cycle phases (follicular, ovulation, and luteal) to assess changes in visual sexual interest. Ovulation status was determined by a self-administered urine test. Results showed that the frequency and arousability of sexual fantasies increased significantly at ovulation. The number of males in the fantasies increased during the most fertile period, with no such change for the number of females. Fantasy content became more female-like during ovulation, focusing more on emotions rather than explicit sexual content. Women displayed a category non-specific pattern of viewing time with regard to target age and gender, regardless of fertility status. Results were discussed in the context of the ovulatory shift hypothesis of female sexuality.

    ABSTRACT: 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.

    ABSTRACT: Quinsey and Lalumière (1995) suggested that some, if not most, paraphilias are exaggerated manifestations of more normative and functional mate selection preferences. The present study tested whether Feederism, a fat fetish focused on erotic eating, feeding, and gaining weight, is an exaggeration of a sexual arousal pattern commonly seen in the general population. Thirty participants (15 men and 15 women) recruited from the general population were assessed using penile plethysmography and vaginal photoplethysmography, respectively. None of the participants were self-identified Feeders or Feedees. Participants were shown sexual, neutral, and feeding still images while listening to audio recordings of sexual, neutral, and feeding stories. Participants did not genitally respond to feeding stimuli. However, both men and women subjectively rated feeding stimuli as more sexually arousing than neutral stimuli. We discuss the discordance between physiological and self-reported sexual arousal in the context of sex differences in sexual concordance and implications for future research.

    ABSTRACT: Studies of bisexual sexual interest have focused mostly on measures of genital arousal in bisexual men and have generally failed to find evidence of a bisexual pattern of genital arousal. Bisexual women have rarely been studied and other measures of sexual interest have not been used to study bisexual interest in either sex. In this study, we examined a non-genital measure of sexual interest, viewing time, among 16 bisexual men, 19 bisexual women, 15 heterosexual men, 15 heterosexual women, 15 homosexual men, and 10 homosexual women. Sexual orientation was determined from a self-report questionnaire. Stimuli were pictures of males and females of all five Tanner stages of sexual development. Participants were asked to rate the sexual appeal of the individuals depicted in the pictures, while the time taken to provide a response was covertly measured. Using a signed index that compared viewing times to pictures of sexually mature males and females, bisexual men and bisexual women did not look longer at pictures of one gender, whereas the other four groups had longer viewing times for pictures of one gender. Using an absolute index, the three groups of women showed a similar (and low) degree of gender preference. All groups showed longer viewing times for sexually mature individuals than for sexually immature individuals, suggesting that the viewing time responses of bisexual men and women were not produced by a general tendency to look indiscriminately at all pictures. There were small to moderate correlations between viewing times and rated sexual appeal in all groups. Results suggest that viewing time can be used to detect a bisexual pattern of sexual interest in bisexual men and bisexual women.
