Social anxiety, sexual behavior, and contraceptive use

Two hundred and sixty college students completed a questionnaire that provided information regarding their sexual experience, knowledge, and attitudes; their self-evaluations on dimensions related to sexuality; and their level of heterosocial anxiety (anxiety experienced in social interactions with members of the other sex). Compared with subjects low in heterosocial anxiety, highly anxious respondents were less sexually experienced, engaged in sexual activity less frequently, had fewer sexual partners, were less likely to have engaged in oral sex, expressed a higher degree of apprehension about sex, and had a somewhat higher incidence of sexual dysfunctions. In addition, low socially anxious women tended to use the pill, whereas highly anxious women preferred the condom. High and low heterosocially anxious respondents also differed on self-ratings related to their sexuality but did not differ in their attitudes or knowledge regarding sex. The results are discussed in terms of the cognitive, behavioral, and affective concomitants of social anxiety.     

Men's heterosocial skill and attitudes toward women as predictors of verbal sexual coercion and forceful rape

This study assessed whether men's heterosocial skill and attitudes toward women are related to verbal and physical sexual coercion in a nonincarcerated population. We predicted that heterosocially skilled men would be more likely than unskilled men to have engaged in verbal sexual coercion, whereas unskilled men would be more likely than skilled men to have engaged in physical sexual coercion (i.e., forceful rape). We expected an interaction, with this pattern holding only for men who accepted traditional gender roles or male sexual dominance; men who did not accept these attitudes were expected to be unlikely to have engaged in either verbal or physical coercion. To identify sexually coercive men, we administered questionnaires to 1152 male introductory psychology students. They completed anonymous self-report measures of (a) heterosocial skill, (b) attitudes toward women, and (c) involvement with verbal and physical sexual coercion. Results showed that heterosocially skilled men were more likely than unskilled men to have engaged in verbal sexual coercion, but heterosocial skill was unrelated to forceful rape. Men who accepted traditional gender roles or male sexual dominance were more likely than other men to have engaged in both verbal sexual coercion and forceful rape. There were no interactions. Theoretical issues and treatment implications are discussed.The authors wish to thank Gayla Goolsby, Trudi Zaplac, Diane Collinge, Shelley Davis, Gina Benedicto, and DiAnne Poehl.

Pavlovian conditioning of sexual arousal: parametric and background manipulations

Recent studies have shown that a Pavlovian conditioned stimulus (CS) for unconsummated sexual arousal can increase the rate of copulation in the rat. This report includes five experiments examining the effects of parametric manipulations on the conditioned arousal response. Results show that between six and nine trials are necessary for reliable conditioning, but extinction is somewhat slower than acquisition. The function for the CS-US (unconditioned stimulus) interval is quadratic, with a minimum of several minutes required for effective conditioning. In the first three experiments, it appeared that background cues were conditioned as well as the designated CSs, and this was tested explicitly in the last two studies. In one, the effect of background cues was shown by training and testing in different situations; in the second, background cues were shown to be subject to latent inhibition. These results demonstrate the influence of Pavlovian learning in sexual behavior and help to provide the basis for an animal model of the acquisition of deviant sexual arousal in humans.     

Does the horny man think women want him too? Effects of male sexual arousal on perceptions of female sexual willingness

ABSTRACT

Disputes over acquaintance rape typically center on the issue of whether the alleged victim consented to sex. Disputed sexual encounters often take place when one or both involved parties is sexually aroused, and this arousal might influence the extent to which the parties perceive sexual consent. Two studies tested the effects of men’s sexual arousal on their interpretations of the extent to which 25 hypothetical female behaviors reflected sexual willingness. Arousal was manipulated via written fantasies (Study 1) or exposure to erotic material (Study 2). Manipulated arousal and individual differences in rated arousal were each associated with greater perceptions of female sexual willingness. Manipulated arousal was significant only for single men in Study 2. Findings suggested present-state sexual arousal affects single men’s interpretations of women’s sexual willingness. Men’s sexual arousal might prominently contribute to misunderstandings in sexual communication.     

The effects of state and trait self-focused attention on sexual arousal in sexually functional and dysfunctional women

This study examined the effects of state self-focused attention on sexual arousal and trait self-consciousness on sexual arousal and function in sexually functional (n=16) and dysfunctional (n=16) women. Self-focused attention was induced using a 50% reflectant television screen in one of two counterbalanced sessions during which self-report and physiological sexual responses to erotic films were measured. Self-focused attention significantly decreased vaginal pulse amplitude (VPA) responses among sexually functional but not dysfunctional women, and substantially decreased correlations between self-report and VPA measures of sexual arousal. Self-focused attention did not significantly impact subjective sexual arousal in sexually functional or dysfunctional women. Trait private self-consciousness was positively related to sexual desire, orgasm, compatibility, contentment and sexual satisfaction. Public self-consciousness was correlated with sexual pain. The findings are discussed in terms of Masters and Johnson's [Masters, W. H. & Johnson, V. E. (1970). Human sexual inadequacy. Boston: Little, Brown) concepts of "spectatoring" and "sensate focus."     

Alcohol and human sexual behavior.

Despite the potential clinical significance of the relationship between alcohol consumption and human sexual responsiveness. the subject has received little systematic research attention. Clinical observations have suggested that alcohol abuse can lead to impotency disorders in males and sexual dysfunction in women. Alcohol has been associated with sex offences such as rape and pedophilia, increased sexual activity and extramarital affairs. However, correlation has been confused with cause, and unequivocal evidence of alcohol as the causal agent is lacking. Recent research using penile tumescence and vaginal pressure pulse as measures of sexual arousal has shown a significant negative linear relation between alcohol and sexual responsiveness in both men and women social drinkers. Findings that cognitive rather than pharmacological factors decisively influence alcohol's effects on sexual arousal, together with other psychosocial analyses, dispute the disinhibition hypothesis of alcohol's effects. A social learning analysis of alcohol's influence on sex is proposed.     

Habituation and dishabituation of female sexual arousal

Measures of subjective and physiological sexual arousal were taken within a session while women either viewed the same segment of erotic film on many occasions or employed the same sexual fantasy over a number of trials. For both film and fantasy there were significant reductions in subjective sexual arousal and average pulse amplitude during the course of repeated erotic stimulation. Subsequent presentation of novel erotic stimuli led to recovery in sexual arousal. Bases for habituation and dishabituation of female sexual arousal are discussed.     

Using a Naturalistic Sport Context to Train Social Skills in Children

ABSTRACT

Researchers have utilized sports activities to deliver social skills training (SST) programs to children. Using a multiple-baseline across behaviors design, we examined whether a brief SST program delivered during a soccer camp would increase social skills and athletic competencies. Each participant’s self-concept, and his interest in soccer were evaluated. Results suggest that the SST procedure effectively increased targeted social skills. Further, participants reported increased interest in soccer and higher overall self-concept. Our results suggest that similar effects can be achieved in a relatively short, but intense, camp that utilizes SST and sports-skill training components. Limitations and implications are discussed.     

The interaction of state and trait aspects of self-focused attention affects genital, but not subjective, sexual arousal in sexually functional women

In this study we investigated the effects of state and trait aspects of self-focused attention on genital and subjective sexual arousal of sexually functional, healthy women during presentation of audiovisual erotic stimuli. Psychophysiological sexual response was measured as vaginal pulse amplitude using a vaginal photoplethysmograph. Experiential aspects of sexual arousal were measured both during stimulus presentation and retrospectively after stimulus offset. Trait level of sexual self-focus was measured with the Sexual Self-Consciousness Scale. State self-focus was induced by switching on a TV camera that pointed at the participant's face and upper torso. A manipulation check revealed that both groups experienced equally elevated levels of self-focused attention of their physical appearance. Induction of state self-focus per se did not affect genital responses, but an interaction effect of self-focus and participants' level of trait sexual self-focus was revealed. Compared with women with low scores on this trait, women with high scores exhibited smaller genital responses when state self-focus was induced. Both groups did not differ when no self-focus was induced. Increase of state self-focus did not affect subjective sexual arousal, but participants with a high level of trait sexual self-focus reported stronger subjective arousal, compared with those with low trait level. The results were discussed with reference to previous work in this field. Some implications for treatment of sexual arousal disorder were discussed.     

Dissociation of sexual arousal and sexual proclivity in the garden snail, Helix aspersa

Sexual arousal (intensity of courtship) and sexual proclivity (tendency to court) in Helix aspersa can be reliably measured using externally observable correlates. Snails with sexual proclivity are significantly more likely to turn toward an anesthetized conspecific after contacting it than are sexually unreceptive snails. Sexual arousal can be inferred from the stage of a snail's genital eversion, which appears only during courtship. The higher the stage of the eversion, the shorter the time required to complete introductory courtship behavior and the higher the rate of successful copulation, the fewer the number of breaks and pauses during courtship, and the longer the time a snail will spend in contact with an anesthetized conspecific. Sexual proclivity has no effect on feeding or locomotory behavior; however, sexual arousal inhibits feeding and increases locomotor activity. Snails that were allowed daily contact with conspecifics required less time to complete introductory courtship behavior relative to snails that were isolated from conspecifics for 1 week. This suggests that daily contact increases sexual arousal. A greater percentage of isolated snails exhibited courtship behavior than did snails which had experienced daily conspecific contact. This suggests that isolation increases sexual proclivity. These differences indicate that sexual arousal is not merely due to an increase in sexual proclivity.     

Neural correlates of subliminally presented visual sexual stimuli

In the context of forensic psychiatry, it is crucial that diagnoses of deviant sexual interests are resistant to manipulation. In a first attempt to promote the development of such tools, the current fMRI study focusses on the examination of hemodynamic responses to preferred, in contrast to non-preferred, sexual stimuli with and without explicit sexual features in 24 healthy heterosexual subjects. The subliminal stimulus presentation of sexual stimuli could be a new approach to reduce vulnerability to manipulation. Meaningful images and scrambled images were applied as masks. Recognition performance was low, but interestingly, sexual preference and explicitness modulated stimulus visibility, suggesting interactions between networks of sexual arousal and consciousness. With scrambled masks, higher activations for sexually preferred images and for explicit images were found in areas associated with sexual arousal (Stoleru, Fonteille, Cornelis, Joyal, & Moulier, 2012). We conclude that masked sexual stimuli can evoke activations in areas associated with supraliminal induced sexual arousal.     

Sexually aggressive and nonaggressive men: sexual arousal and judgments in response to acquaintance rape and consensual analogues

Self-identified sexually aggressive (SA) and nonaggressive (NA) college men listened to audiotape analogues of consensual sexual intercourse and acquaintance rape. Phallometric and decision-latency methodology was used to examine sexual arousal and decisions to stop sexual advances in each scenario. Both groups showed increases in penile response to the consensual scenario. Consistent with the inhibition model of sexual aggression, the SA group showed greater sexual arousal and failed to inhibit responding when force was introduced in the rape, whereas the NA group exhibited less arousal and greater inhibition to force. The SA group allowed the rape to continue significantly longer than the NA group. These effects were greatly magnified in SA men who endorsed high calloused sexual beliefs, implying that a cognitive set that justifies sexual aggression and lacks victim empathy may disinhibit sexual arousal and potentiate coercive decision making.     

Sexual submissiveness in women: costs for sexual autonomy and arousal

Women are bombarded with images of women's sexual submission and subservience to male partners. The authors argue that women internalize this submissive role, namely, they associate sex implicitly with submission. The authors propose that this association leads to submissive sexual behavior, thereby reducing sexual autonomy and arousal. Study 1 found that women implicitly associated sex with submission. Study 2 showed that women's implicit association of sex with submission predicted greater personal adoption of a submissive sexual role. Study 3 found that men did not implicitly associate sex with submission. Study 4 demonstrated that women's adoption of a submissive sexual role predicted lower reported arousal and greater reported difficulty becoming sexually aroused; sexual autonomy mediated these effects.     

Men's likelihood of sexual aggression: the influence of alcohol,sexual arousal,and violent pornography

Previous research findings have indicated that both alcohol intoxication and violent pornography exposure may contribute to increased sexual aggression by men. This study used an experimental paradigm to examine the effects of a moderate alcohol dose, alcohol‐related beliefs, and victim response on men's self‐reported likelihood of committing sexual aggression. A community sample of male social drinkers (N=84) participated in an experiment in which they read an eroticized rape depiction after completing an alcohol administration protocol. The stimulus story varied whether the victim, who initially expressed unwillingness to engage in sexual activity, expressed pleasure or distress in response to the man physically forcing her to perform several explicit sex acts. A path analytic model illustrated that participants' self‐reported likelihood of behaving like the sexual aggressor in the story was directly related to their own sexual arousal. Heightened sexual arousal was reported by participants who had consumed alcohol, those who read the victim‐pleasure story, and those who believed that drinking women are sexually vulnerable. Results suggest that sexual arousal to violent pornography, as influenced by acute alcohol intoxication and other factors, may be an important component of men's perceptions of their own sexual aggression likelihood.

The role of sexual arousal and sexual partner characteristics in HIV+ MSM's intentions to engage in unprotected sexual intercourse

OBJECTIVE: This study investigated the effects of sexual arousal and sexual partner characteristics as determinants of HIV+ men who have sex with men's (MSM) intentions to engage in unprotected sex. DESIGN: In a computer-based controlled experiment, 67 HIV+ MSM underwent a sexual arousal manipulation and indicated their intentions to engage in unprotected sex with hypothetical partners who differed in terms of HIV serostatus, physical attractiveness, relationship type, and preference for condom use. MAIN OUTCOME MEASURES: Computer-delivered questions assessed HIV+ MSM's intentions to engage in various sexual acts with each hypothetical partner. RESULTS: As predicted, sexually aroused HIV+ MSM indicated stronger intentions to engage in unprotected sex than nonaroused HIV+ MSM; and having a partner who was attractive, HIV+, long term, or who preferred not to use condoms, also led to riskier intentions. Several significant interactions among these factors were found, which were generally consistent with predictions and with theory and research on cognitive processing and decision making. CONCLUSIONS: These findings have implications for understanding risky sexual behavior among HIV+ individuals and for the development of interventions to reduce this risk.     

Evaluation of a sexual abuse prevention program for adults with mental retardation.

Programs to teach sexual abuse prevention skills to persons with mental retardation have rarely been evaluated empirically, and typical evaluations are limited to assessment of the participants' knowledge rather than their performance of specific skills. In the present study, 6 adult women with mental retardation were trained in sexual abuse prevention, and performance was assessed using four separate measures: pretests and posttests of knowledge, verbal report, role play, and naturalistic probes. All women learned the skills but failed to exhibit them to criterion during the probes. We discuss the implications for further training and assessment of sexual abuse prevention skills.     

A sex difference in the specificity of sexual arousal

Sexual arousal is category-specific in men; heterosexual men are more aroused by female than by male sexual stimuli, whereas homosexual men show the opposite pattern. There is reason to believe that female sexual arousal is organized differently. We assessed genital and subjective sexual arousal to male and female sexual stimuli in women, men, and postoperative male-to-female transsexuals. In contrast to men, women showed little category specificity on either the genital or the subjective measure. Both heterosexual and homosexual women experienced strong genital arousal to both male and female sexual stimuli. Transsexuals showed a category-specific pattern, demonstrating that category specificity can be detected in the neovagina using a photoplethysmographic measure of female genital sexual arousal. In a second study, we showed that our results for females are unlikely to be explained by ascertainment biases. These findings suggest that sexual arousal patterns play fundamentally different roles in male and female sexuality.     

Sexual arousal in response to aggression: ideological, aggressive, and sexual correlates

In two experiments we assessed the impact of aggression on nonrapists' sexual arousal. In the first, both male subjects (n = 37) and female subjects (n = 43) reported more sexual arousal in response to nonaggressive than to aggressive depictions when the portrayals were sexually explicit, but the opposite occurred when the portrayals were nonsexual. Only male subjects (N = 359) participated in the second experiment. On the basis of their self-reported sexual arousal to the use of force, they were classified into the no arousal, moderate arousal or high arousal from force groups. To evaluate the veridicality of this classification, we assessed some subjects' (n = 118) penile tumescence in response to various depictions. The findings generally replicated those of the first experiment and confirmed the accuracy of the arousal-from-force classification. The no arousal and the moderate arousal from force subjects were less sexually aroused by aggressive than by nonaggressive portrayals, but the opposite was found for the high arousal from force group. Using the entire sample (N = 359), we also assessed differences on various factors among these three groups. We found strong differences on ideological factors, including acceptance of violence against and dominance over women. We also found differences in acceptance of nonsexual aggression and in subjects' beliefs that they might actually use force against women. In contrast, differences were not found on sexuality factors. The data's implications for theories on the causes of rape are discussed.
