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.     

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.

Pornography,preference for porn‐like sex,masturbation, and men's sexual and relationship satisfaction

Pornography use, preference for “porn‐like” sex, masturbation, and sexual and relationship satisfaction were assessed among two samples of men (N_{Study 1} = 326, N_{Study 2} = 335). Frequent pornography use was associated with sexual dissatisfaction, greater preference for porn‐like sex, and more frequent masturbation in both studies. Pornography use was associated with relationship dissatisfaction in Study 2 only. The data did not support the notion that pornography negatively impacts sexual or relationship satisfaction via preference for porn‐like sex. In fact, it may bolster sexual satisfaction by promoting sexual variety. The data were consistent with a model in which pornography negatively, indirectly affects sexual and relationship satisfaction via masturbation frequency. Pornography use may have multiple opposing influences on sexual satisfaction.     

Gender,sexual orientation,and disordered eating

Abstract

While most patients with bulimia nervosa are heterosexual women, a significant number of men with bulimia nervosa are gay males, suggesting that gay men, more than heterosexual men, may be at risk for developing eating disorders. This study compared the food-related attitudes and behaviors of heterosexual men and women in contrast with those of lesbians and gay men, attempting to find whether one's sexual orientation may contribute to differential risk. Two thousand employees were randomly selected from a large health care corporation, of whom 805 returned a completed questionnaire including Stunkard and Messick's (1985) Dietary Restraint and Disinhibition Scales. A stratified random sample was drawn to include demographically comparable groups of 25 lesbians, 50 gay men, 75 heterosexual women, and 75 heterosexual men. Women were less satisfied with their appearance at their present weight and expressed more restraint and more negative feelings after bingeing than did men. Heterosexual women were most dissatisfied with their weight, although heterosexual men were more objectively overweight. Gay men and heterosexual women were similar in disordered eating patterns and disinhibition, contrasting with lesbians and heterosexual men.     

Hostile masculinity,sexual aggresion,and gender-biased domineeringness in conversations

This study assessed the ability of certain variables to predict which men would be more domineering in conversations with a woman and/or with a man. The variables included men's self-reported sexually aggressive behavior and several components comprising a personality profile labeled “Hostile Masculinity.” As expected, these variables successfully predicted domineering behavior toward the female but not toward the male. These findings supported theories hypothesizing that men's desire to control women and men's antisocial behavior toward them are due to specific rather than to general factors (i. e., evolutionary and feminist theorizing). © 1994 Wiley-Liss, Inc.     

Body appreciation,sexual relationship status,and protective sexual behaviors in women

The relationship between body appreciation and sexual risk reduction behavior in women is under-explored. This cross-sectional study examined the relationships between body appreciation, male condom use, and sexually transmitted infection (STI) testing among a community-based sample of women (n = 285). Logistic regression results revealed that after controlling for age, BMI, and sexual orientation, having more than one sexual partner moderated body appreciation and current male condom use (OR = 4.21, p < .01, CI = 1.510–11.726). Body appreciation was not a significant predictor of STI testing in the previous 12 months. This suggests that women with higher body appreciation may be more likely to engage in some protective sexual health behaviors. Interventions that seek to improve body appreciation instead of body size change such as weight loss or gain may encourage certain protective sexual behaviors in women.     

The nature of sexual reinforcement.

Sexual reinforcers are not part of a regulatory system involved in the maintenance of critical metabolic processes, they differ for males and females, they differ as a function of species and mating system, and they show ontogenetic and seasonal changes related to endocrine conditions. Exposure to a member of the opposite sex without copulation can be sufficient for sexual reinforcement. However, copulatory access is a stronger reinforcer, and copulatory opportunity can serve to enhance the reinforcing efficacy of stimulus features of a sexual partner. Conversely, under certain conditions, noncopulatory exposure serves to decrease reinforcer efficacy. Many common learning phenomena such as acquisition, extinction, discrimination learning, second-order conditioning, and latent inhibition have been demonstrated in sexual conditioning. These observations extend the generality of findings obtained with more conventional reinforcers, but the mechanisms of these effects and their gender and species specificity remain to be explored.     

Aggressive behavioral characteristics,hormones, and sexual orientation in men and women

Aggressive behavioral characteristics were assessed in groups of men and women by a self-report instrument, the Aggression Inventory, in which adult males reported more physical and verbal aggression than did females. Furthermore, males had higher scores on measures of impulsiveness and lack of frustration tolerance than did females, while women were more likely to avoid confrontation. In a second study, groups of male and female homosexuals and heterosexuals completed this Aggression Inventory after having blood samples taken to assay resting levels of testosterone (T) and estradiol (E). Groups of subjects within each gender were closely matched in terms of age, education, and vocational interests. Women were matched for the same time in their menstrual cycle (early follicular phase). Among men, homosexuals were indistinguishable from heterosexuals on all measures of aggression. Lesbians did not differ from heterosexual women on any aggression subscale except physical aggression, in which the homosexual women had lower scores. T and E were positively correlated with several indices of aggressive behavioral characteristics in men but were negatively correlated with those same measures in women.     

Self-objectification,body self-consciousness during sexual activities,and sexual satisfaction in college women

Few studies examine the mechanisms that link body image to sexual satisfaction in women. Using the tenets of objectification theory, this study investigated the relationships between body surveillance, body shame, body self-consciousness during sexual activities, and sexual satisfaction in an ethnically diverse sample of American female college students (N = 368), while controlling for relationship status and body mass index. Results based on self-report measures of these constructs suggested that body shame and body self-consciousness during sexual activity were negatively correlated with sexual satisfaction. Additionally, path analysis indicated that body surveillance predicted increased body self-consciousness during sexual activity, partially mediated by body shame. Body self-consciousness, in turn, predicted decreased sexual satisfaction. Overall, study findings highlight the negative consequences of body image concerns for women's sexual satisfaction.     

The relationship between conformity to gender norms,sexual orientation,and gender identity for sexual minorities

The current study examined how dimensions of masculinity and femininity were expressed for sexual minorities. Cluster analysis was used to determine the number of latent classes for conformity to masculine and feminine norms for sexual minorities. A four-class solution was the best fit to the data. Cluster 1 (labeled Relating to others through equality and caring, n = 41) was characterized by low dominance and power over women and high involvement with kids and have nice relationships norms. Cluster 2 (labeled Relating to others through avoidance and misogyny, n = 38) was characterized by low risk-taking and have nice relationships and high power over women and disdain for homosexuality. Cluster 3 (labeled Relating to others through power, n = 34) was characterized by high winning, pursuit of status, and appearance and low modesty. Cluster 4 (labeled Relating to others through sex, n = 27) was characterized by low involvement in romantic relationships and sexual fidelity while endorsing high playboy attitudes. Results indicate that conforming to gender norms tends to follow categories of interpersonal beliefs and behaviors rather than being based in gender identity or sexual orientation. Implications of the results for future research and clinical practice are examined.     

The effects of alcohol intoxication and sexual interest on men's sexual persistence and hostility in a dating simulation

Perpetrators of sexual assault are often intoxicated; however, few experimental studies evaluate alcohol's “in the moment” effects on sexual aggression. This study extends past theory and research by examining the acute effects of alcohol on men's decisions about how to respond to sexual refusals in a dating simulation. Men (N = 62) ages 21–29 were randomly assigned to consume alcohol (target breath alcohol level 0.080%) or no alcohol. Participants were encouraged to talk to a simulated woman and act as they would on an actual date. They made choices from a list which included nonsexual and sexual options. The female agent was programmed to engage in some sexual activities but refuse others. Refusals became more intense if participants persisted. Negative binomial regression analysis was used to test a path analytic model. As predicted, participants' self‐reported desire to have sex was positively associated with choosing more consensual sexual activities during the simulation (i.e., activities in which the woman willingly engaged). Consensual sexual activities were positively associated with the number of times participants persisted after the woman refused. Alcohol moderated this relationship such that it was stronger for intoxicated men than sober men. The more sexual refusals participants received, the more hostile verbal comments they made to the woman. Contrary to our predictions, this relationship was not moderated by alcohol condition. Because participants had multiple opportunities to escalate their aggression or desist, this paradigm provides new insights into the mechanisms through which intoxication enhances the likelihood of sexual aggression in dating situations.

     

Assessment of sexual preference using a choice reaction time task

The purpose of this study was to investigate the use of a choice reaction time task, during which slides of sexually explicit and neutral stimuli were used as an interference task, to differentiate between groups of individuals on the basis of their sexual preference. Twenty subjects, in each of the four groups (heterosexual males, heterosexual females, homosexual males, and homosexual females), participated in this study. Sexual orientation was determined by self-report. Subjects were given a choice reaction time with interference task, followed by a recall incidental learning task. A significant higher-order interaction was found among gender, orientation, and stimulus type for all four groups. This interaction indicated a longer reaction time to slides depicting preferred sexual partners than to nonpreferred sexual partners or neutral scenes. These results indicate that sexual arousal does interfere with cognitive processing. A main effect for gender was found for the incidental learning task, with males having the fewest errors.     

Cognitive and physiological indices of sexual arousal in homosexual,bisexual, and heterosexual males

Cognitive and physiological indices of sexual arousal were investigated utilizing groups of homosexual, bisexual, and heterosexual subjects (ten subjects per group) who were presented both homosexual and heterosexual films and slides. The results indicated that both homosexual and heterosexual subjects were able to estimate accurately their degree of erection to the erotic stimuli. Bisexual subjects, however, showed a large discrepancy between the magnitude of actual erection and verbally reported estimates of penile tumescence. In terms of physiological arousal, the erectile responses of the homosexual and bisexual groups were indistinguishable, a finding which questions the existence of male bisexuality as distinct from homosexuality or as a different sexual orientation in males.     

Let's talk openly about sex: Sexual communication,self-esteem and efficacy as correlates of sexual well-being

Drawing from theories of sexual development, the aim of this study was investigate whether sexual well-being was more positive when youth reported more frequent and better quality sex-related communication, and greater sexual subjectivity (sexual body esteem and pleasure self-efficacy). Sexual well-being was measured with reference to partnered behaviour, including safe-sex behavioural competence, sexual assertiveness, and emotional reactions. Young adults (N = 209; 61% female) aged 17–21 completed questionnaires. While also considering age, gender, romantic status and coital experience in regression analyses, participants higher in competence reported more frequent communication with mothers in high school, and current higher quality communication with mothers and friends. Participants reported more positive emotions related to sex when they had better quality communication with their friends. Associations of sexual subjectivity with greater sexual well-being were found, and small indirect effects were found between retrospectively reported communication frequency and sexual well-being via pleasure self-efficacy.     

Negative urgency and risky sexual behaviors: A clarification of the relationship between impulsivity and risky sexual behavior

How does impulsivity relate to risky sexual behavior? Whereas some research has attempted to answer this question in terms of global impulsivity, past research has demonstrated the need to conceptualize impulsivity as a multifaceted trait (Whiteside & Lynam, 2001). Research has been mixed as to which facets of impulsivity predict risky sexual behavior. The major aim of this project was to further the understanding between the five facets of impulsivity (positive urgency, negative urgency, lack of premeditation, sensation-seeking, and lack of perseverance) and risky sexual behavior. This study used a longitudinal design and showed that risky sex was highest among people who act rashly on the basis of negative emotion (negative urgency) and who crave novel, exciting situations (sensation seeking). These findings add to a growing body of literature on the importance of different facets of impulsivity in predicting risky sexual behavior.     

Psychopathic traits,gender, and motivations for sex: Putative paths to sexual coercion

Evidence suggests that both men and women perpetrate sexual coercion. Psychological factors, including psychopathic traits and power motivations, have been proposed to characterize male-perpetrated sexual coercion; however, it is unclear whether these factors play a similar role in female-perpetrated coercion or whether other motivations (e.g., intimacy, affect regulation) should be considered. To improve our understanding in this area, the current study first examined relationships between psychopathic traits and sexual coercion in a sample of 1199 undergraduate students (756 women), with gender as a potential moderator of these relationships. Second, the role of motivations for sex (e.g., power, affect regulation) in accounting for the psychopathy-coercion relationship was examined in men and women. Data were collected using an online survey and analyzed using multigroup path analysis. Results implicated impulsive-antisocial traits as particularly important to male-perpetrated verbal (e.g., manipulative) and nonverbal (e.g., physical) coercion, and that this relationship was partially explained by motives for sex involving power. In contrast, psychopathic traits did not appear to play a major role in female perpetrated coercion; instead, emotional value (i.e., intimacy-related) motivations for sex were associated with verbal (e.g., manipulation) coercion in women. In sum, our results support a conceptual model of male perpetration where men who are high in impulsive-antisocial traits may engage in sexual coercion in an attempt to feel powerful. Further, the findings in the female sample suggest that factors other than psychopathy, such as gender role beliefs in regard to sexual encounters, may be particularly important to female perpetrated sexually coercive behavior.
