The sexual responses of sexual sadists

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.

Gender and sexual orientation differences in sexual response to sexual activities versus gender of actors in sexual films

In this study, the authors investigated the hypothesis that women's sexual orientation and sexual responses in the laboratory correlate less highly than do men's because women respond primarily to the sexual activities performed by actors, whereas men respond primarily to the gender of the actors. The participants were 20 homosexual women, 27 heterosexual women, 17 homosexual men, and 27 heterosexual men. The videotaped stimuli included men and women engaging in same-sex intercourse, solitary masturbation, or nude exercise (no sexual activity); human male-female copulation; and animal (bonobo chimpanzee or Pan paniscus) copulation. Genital and subjective sexual arousal were continuously recorded. The genital responses of both sexes were weakest to nude exercise and strongest to intercourse. As predicted, however, actor gender was more important for men than for women, and the level of sexual activity was more important for women than for men. Consistent with this result, women responded genitally to bonobo copulation, whereas men did not. An unexpected result was that homosexual women responded more to nude female targets exercising and masturbating than to nude male targets, whereas heterosexual women responded about the same to both sexes at each activity level.     

Relationship between short-term sexual strategies and sexual jealousy

In a classic study, Buss, Larson, Westen, and Semmelroth reported that men were more distressed by the thought of a partner's sexual infidelity (sexual jealousy) and women were more distressed by the thought of a partner's emotional infidelity (emotional jealousy). Initially, Buss and his associates explained these results by suggesting that men are concerned about uncertainty of paternity, that is, the possibility of raising another man's child while believing the child is their own. However, later they explained the results in terms of men's preference for short-term sexual strategies. The purpose of this research was to test the explanation of short-term sexual strategies. Men and women subjects were instructed to imagine themselves in a relationship which was either short-term (primarily sexual) or long-term (involving commitment) and then respond to Buss's jealousy items. It was hypothesized that, when both men and women imagined a short-term relationship, they would be more threatened by a partner's sexual infidelity, and, when they imagined a long-term relationship, they would be more threatened by a partner's emotional infidelity. Support was found for this hypothesis.     

The credibility of sexual abuse allegations: Child sexual abuse, adult rape, and sexual harassment

Allegations and denials of sexual abuse often occur in a context in which there is rarely decisive evidence. The present study investigated the credibility of allegations of three kinds of sexual abuse—child sexual abuse, adult rape, and sexual harassment—that also contained a denial by the alleged perpetrator. Perceptions of fair punishment were investigated for the perpetrator if he did actually commit these acts and for the accuser if she was lying. Results indicated that allegations were generally rated in the credible direction. Allegations of child sexual abuse were rated more credible than allegations of rape or sexual harassment. Females found all allegations more credible than males. Males were more likely to believe allegations in the child sexual abuse condition than either the rape or sexual harassment conditions. Females were more likely to believe sexual harassment allegations. Punishments were generally the most severe for child sexual abuse, and psychotherapy was a popular disposition for both perpetrators and those making false allegations.     

Greater exposure to sexual content in popular movies predicts earlier sexual debut and increased sexual risk taking

Early sexual debut is associated with risky sexual behavior and an increased risk of unplanned pregnancy and sexually transmitted infections later in life. The relations among early movie sexual exposure (MSE), sexual debut, and risky sexual behavior in adulthood (i.e., multiple sexual partners and inconsistent condom use) were examined in a longitudinal study of U.S. adolescents. MSE was measured using the Beach method, a comprehensive procedure for media content coding. Controlling for characteristics of adolescents and their families, analyses showed that MSE predicted age of sexual debut, both directly and indirectly through changes in sensation seeking. MSE also predicted engagement in risky sexual behaviors both directly and indirectly via early sexual debut. These results suggest that MSE may promote sexual risk taking both by modifying sexual behavior and by accelerating the normal rise in sensation seeking during adolescence.     

Implicit motives and sexual conservatism as predictors of sexual behaviors

This study was designed to provide an assessment of the relationship between the two most important implicit motives and the most frequently studied sexual behaviors. A community sample of 102 men and 92 women completed measures of implicit power and affiliation-intimacy motives, sexual conservatism, social desirability, and sexual behavior. For men, high power motivation was positively associated with the number of sexual partners and the frequency of sex. There was an interaction between sexual conservatism and power motivation in women. For women low in sexual conservatism, high power motivation was positively associated with the number of sexual partners and with earlier initiation to intercourse and oral sex. There were few associations between affiliation-intimacy motivation and sexual behaviors; however, women high in this motive reported later initiation to oral sex.     

Effects of emotional state on sexual desire and sexual dysfunction

The present study explored effects of emotional states on sexual desire and dysfunction. Three basic emotion dimensions, pleasure-displeasure, arousal-nonarousal, and dominance-submissiveness, served as the independent factors. Factor analysis of a sexual desire and problems questionnaire yielded a single factor with sexual desire as one pole and sexual problems as the opposite pole. The resulting sexual desire scale had a KR-20 reliability coefficient of .98 and constituted a highly homogeneous dependent measure. Sexual desire was greater when subjects felt pleasure rather than displeasure, unaroused rather than aroused, and dominant rather than submissive. Desire increased with increasing arousal in pleasant states and decreased with increasing arousal in unpleasant states (Pleasure × Arousal interaction). Desire increased with increasing dominance in pleasant states and decreased with increasing dominance in unpleasant states (Pleasure × Dominance interaction). In unaroused states, submissiveness attenuated the polarization of sexual desire as a function of pleasure-displeasure (Pleasure × Arousal × Dominance interaction). The highest levels of sexual desire and freedom from sexual problems were associated with pleasant and dominant feelings (e.g., admired and vigorous or relaxed and leisurely); the lowest levels were reported for unpleasant and aroused feelings (e.g., hostile and hateful or pained and embarrassed). Except for the uniformly greater sexual desire of males than of females across all conditions, all findings were applicable equally to the two sexes.     

Adolescent sexual behavior

What is known about adolescent sexual behavior is reviewed. First, the onset of sexual behavior in the teenage years is considered as a function of cohort, gender, and ethnic differences. Omissions in the research on sexual behavior other than intercourse are highlighted. Possible biological, social, and social cognitive processes underlying teenage sexual behavior are then considered. Next, demographic trends in the use of contraceptives and antecedents of regular birth control use are reviewed. Finally, some of the successful program initiatives directed toward altering sexual and contraceptive practices are discussed, keeping in mind the importance and relative lack of well-designed and carefully evaluated programs.     

Men's sexual self-schema

Sexual self-schemas are cognitive generalizations about sexual aspects of oneself. In Part 1, a measure of men's sexual self-schema is developed. Studies of test-retest and internal consistency reliability and validity studies of factor analysis, internal structure, convergent and discriminant validity, process, group difference, and change are provided. The construct consists of 3 dimensions: passionate-loving, powerful-aggressive, and open-minded-liberal traits. In Part 2, the data suggest that men's sexual schema is derived from past sexual experience, is manifest in current sexual experience, and guides future sexual behavior. In Part 3, the data document the cognitive processing aspects of sexual schema. Consistent with the investigators' schema research with women, these data substantiate the importance of cognitive representations of sexuality.     

Impulsive-compulsive sexual behavior

Impulsive-compulsive sexual behavior is a little studied clinical phenomenon which affects approximately 5% to 6% of the population. In the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition-Text Revision, it is classified as an impulse control disorder not otherwise specified or a sexual disorder not otherwise specified. It may be placed in a possible new category in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition called substance and behavioral addictions. This clinical entity is reviewed and the merit of classifying it as an addiction is assessed. Information is presented regarding its diagnostic criteria, epidemiology, types of behavior it can involve, relationship to hypersexuality, comorbidities, treatment, and etiology. The data regarding this disorder and its overlap with chemical addiction is limited. If the two disorders are to be grouped together, further data are needed.     

Proving sexual assault

The framework provided by therapeutic jurisprudence is used to examine the rules of evidence that govern sexual assault trials. The concern is with the impact of the trial process on the accusing witness.In the first part a personal narrative is used to put the legal rules in context. Psychological sources are used in discussing the reasons for presenting such a narrative.In the second part, the effect of statutory changes to the common law rules as effected in NSW in 1981 is analyzed. Drawing upon the Heroines of Justice report the paper suggests that the intention of reducing the trauma of the victim has not yet been achieved. It is suggested that this failure is not unique. A change in attitude on the part of those involved in the trial process is necessary, and the hope is that this paper might contribute to such a change.     

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.
