Genital and psychoaffective response to erotic stimulation in sexually functional and dysfunctional men.

To understand the sexual response patterns of men with premature ejaculation and erectile dysfunction, the authors compared genital and affective responses of sexually functional and dysfunctional men with 3 types of sexual stimulation: an erotic video, penile vibrotactile stimulation, and a combination of both. Genital response differed across both groups and stimulus conditions, with an interactive effect indicating that groups showed different response patterns depending on the stimulation. Affective responses also differed across groups and interacted with stimulus conditions. The combination genital and affective response was superior to either alone in distinguishing men with no sexual problems from those with erectile or ejaculatory problems (or both). These factors were particularly useful in discriminating men with premature ejaculation from those with combined premature ejaculation and erectile dysfunction.

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.

Motivational factors in nonincarcerated sexually aggressive men.

Research on convicted rapists has demonstrated the importance of several key motivational factors in male sexual aggression. In particular, anger at women and the need to dominate or control them have been repeatedly implicated. Although anger and power have also been shown to be important in understanding college men who report sexually aggressive behavior, there has been little research on what underlies these motives. This research combined questions assessing these underlying motivational factors, as well as questions dealing with underlying sexual motivation and disinhibition, with a slightly modified version of the Sexual Experiences Survey (Koss & Oros, 1982). In Study 1, subjects were 184 male undergraduates. Factor analysis of the questions composing the four scales yielded four slightly modified scales. Scales measuring underlying anger, underlying power, and disinhibition significantly differentiated sexually aggressive from nonaggressive men but did not distinguish between men who were coercive, manipulative, or nonaggressive. In a replication on a smaller sample (n?=?70), underlying anger, underlying power, and disinhibition again differentiated sexually aggressive from nonaggressive men.

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

In Exp I, 37 male and 42 female undergraduates 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. In Exp II, 367 males were classified into no arousal, moderate arousal, or high arousal from force (AFF) groups on the basis of self-reports. To evaluate the veridicality of this classification, 118 Ss' penile tumescence in response to various depictions was assessed. Findings generally replicate those of the Exp I and confirm the accuracy of the AFF classification. The no- and the moderate-AFF Ss were less sexually aroused by aggressive than by nonaggressive portrayals, but the opposite was found for the high-AFF group. Strong differences between AFF groups were found on ideological factors, including acceptance of violence against and dominance over women, acceptance of nonsexual aggression, and Ss' beliefs that they might actually use force against women. In contrast, differences were not found on sexuality factors. Implications for theories on the causes of rape are discussed.

The role of sexual arousal in sexually aggressive behavior: A meta-analysis.

Meta-analyses were performed on 9 studies of 434 Ss' penile responsivity to rape stimuli. The mean effect size for raw score data suggested that most sexual aggressors against women exhibit slightly more rape arousal than control or comparison Ss, whereas the mean effect size for rape index (rape arousal:consenting sexual arousal) data suggested a moderate between-groups difference. Rape index effect sizes in individual studies, however, were heterogeneous. The rape index appears sensitive to differences between sexually aggressive men and those who are not but is not sensitive to differences between men who sexually aggress against women vs other types of sexual aggressors. Also discussed are the needs for standardization and methodological and statistical improvements. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Biographical and self-report correlates of female guilt responses to visual erotic stimuli.

Divided 60 female undergraduates into high- and low-sex guilt groups on the basis of their responses to D. L. Mosher's True-False Guilt Inventory. All Ss reported an increase in state of sexual arousal after viewing erotic stimuli. None of the Ss reported any significant difference in state of guilt after viewing the stimuli. Low-sex guilt Ss rated the masturbation, coitus, and petting stimuli as more sexually arousing, better, more pleasant, safer, and more appealing than did high-sex-guilt Ss.

Personality and attitudinal characteristics of sexually coercive college males.

To identify the characteristics of male participants in coercive sexual activities, 190 college males completed a survey of their involvement in coercive sexual behavior and a battery of measures selected to reflect conceptually relevant dimensions of coercive sexuality, including the short form of the Attitudes Toward Women Scale and the scales from the California Psychological Inventory. Consistent with reports in the literature, Ss reported being involved in a wide spectrum of sexually coercive behaviors. The degree of involvement in sexually coercive behavior covaried with personality measures of irresponsibility, a lack of social conscience, and a value orientation legitimizing aggression, particularly against women. Data suggest that these characterological features were necessary to potentiate the general cultural context of coercive sexuality into personally coercive sexual behavior.

Emotional arousal and aggressive behavior

Reviews evidence that (a) supported the proposition that general emotional arousal facilitates aggression in the presence of aggressive cues and (b) substantiated the position that an arousal state of anger specifically increases the instigation to aggression. Furthermore, research is reviewed which supports the view that additional general arousal increases or decreases the effect of anger on aggression, depending on whether the arousal state is attributed to the source of the anger or to another source of general arousal. Controversy about the anger/aggression relation is discussed in terms of the failure to specify the function of the aggressive response. Research revealed that if the aggressive response is directed primarily toward injuring the target (but not toward some other goal), an angered person expresses aggression.

Young school-age sexually aggressive children.

As the full spectrum of sexual abuse sequelae is becoming known, a subset of child victims has been noted to exhibit sexually aggressive behavior. Their sexual behavior far exceeds the mutual exploratory behavior normally seen in young children and resembles more closely the behavior of older sex offenders. We present data from the psychological evaluation of twenty-two 4- to 11-year-old children referred for sexually aggressive behavior, including intellectual, behavioral, projective, and parent–child relational quality. Behavior problem data from these children are contrasted with data from twenty-two 5- to 13-year-old boys who completed a sexual abuse treatment program. Some differences appear related to the development of sexual aggression (e.g., aggression level, nature of the abuse, and family functioning) and are discussed.

Sexual arousal to rape depictions: Individual differences.

145 male undergraduates participated (a) in an orientation session in which personality variables, sexual motivations, sexual experience, and self-reported likelihood of raping were assessed and (b) in a laboratory session in which they listened to 1 of 8 audiotaped depictions of an interaction involving sexual acts between a man and a woman. The content of these depictions was systematically manipulated along the dimensions of consent, pain, and outcome. Later in the 2nd session, Ss listened to a 2nd audiotaped portrayal of either nonconsenting or consenting sex. Their sexual arousal was assessed throughout this 2nd session by penile tumescence and self-reports. Results highlight the importance of the interaction between individual differences variables and manipulations in the content of the portrayals in affecting sexual arousal to rape depictions. Support was obtained for the prediction that such arousal is not an isolated response but is associated with other measures of sexually aggressive tendencies.

Sexual arousal to rape and consenting depictions: The importance of the woman's arousal.

143 male and female undergraduates were randomly assigned to read 1 of 8 versions of an erotic passage. The independent variables in the stories were nonconsent vs consent, woman's arousal vs disgust, and woman's pain vs no pain. Sex of S was the 4th independent variable. Data indicate that both in terms of experimentally manipulated variables and individual within-cell perceptual differences, the outcome dimension (arousal vs disgust) was the only variable that significantly affected Ss' sexual arousal. Portrayals that depicted the woman as experiencing sexual arousal, irrespective of whether they portrayed rape or consenting interactions, were reported by Ss to be more sexually stimulating than those depicting disgust.

Reactions of convicted rapists to sexually explicit stimuli.

Describes a study in which 28 convicted rapists and 28 controls convicted of nonsexual crimes were shown a series of slides depicting sexual themes (young couple in a romantic pose, nude female, male masturbating, heterosexual petting, heterosexual fellatio, heterosexual coitus, and sadomasochism) while measures of penile volume, GSR, and subjective ratings were obtained. Following this presentation, S rated all 7 slides on semantic differential scales. No significant differences were found between groups on the penile volume measures, but the rapists displayed greater arousal on the GSR measures and gave more negative ratings to the sexual themes than controls. This finding suggests that the stimuli were unpleasant for the rapists, supporting previous research. (18 ref.) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of erotic stimuli on male aggression toward females.

To examine the effects of highly erotic films on aggression toward females, 72 male undergraduates were first either angered or treated in a neutral manner by a male or female confederate. After viewing a highly erotic or a neutral film, Ss were given an opportunity to both aggress against and reward the confederate. Erotic films were found to increase aggression overall, but there was no indication of differential aggression as a function of sex of target. Results for physiological arousal, however, suggested that aggression was possibly inhibited for Ss exposed to an erotic film and paired with a female. Suggestions for future lines of research based on the notion of inhibition are offered, along with observations regarding the sexual arousal and aggression relationship.

The effect of emotional arousal on subsequent sexual arousal in men.

The effect of emotional arousal on subsequent sexual arousal was assessed in 14 18–34 yr old men. Ss initially viewed either 1 of 2 emotionally arousing videotapes (depression-and-anger or anxiety-and-anger producing) or a neutral videotape (a travelogue), each of which was followed by an erotic videotape. Sexual arousal was measured physiologically with a penile strain gauge. Although there were no differences in the level of sexual arousal during the antecedent emotionally arousing or neutral videotapes, sexual arousal during the subsequent erotic videotapes was differentially affected by them. Sexual arousal following the anxiety-and-anger videotape was greater than that following either the depression-and-anger videotape or the travelogue. Prior exposure to the travelogue resulted in greater sexual arousal than did the videotape producing depression and anger. (10 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of alcohol and cognitive set on sexual arousal to deviant stimuli.

48 undergraduate male social drinkers were randomly assigned to 1 of 2 expectancy set conditions in which they were led to believe that the beverage they were administered contained alcohol or no alcohol. For half of the Ss in each expectancy condition, the beverage was an alcoholic malt liquor; the others drank a nonalcoholic malt beverage. After their drinks, changes in penile tumescence (PT) in response to normal and deviant tape recordings and to self-generated fantasy were measured physiologically by a mercury-in-rubber strain gauge. The cognitive set (expectancy) significantly increased PT in response to the various erotic recordings. Alcohol did not significantly influence levels of sexual arousal. Ss who believed they had consumed an alcoholic beverage evidenced significantly more arousal to the forcible rape recording and to the sadistic stimuli than Ss who believed that they had consumed a nonalcoholic beverage, regardless of the actual contents of the beverage. The cognitive set, as well as the alcohol, significantly influenced heart rate, skin temperature, and subjective reports of sexual arousal. Self-report measures of sexual arousal were positively correlated with PT. Mosher Forced-Choice Guilt Inventory scores were not significantly correlated with PT, although the Sex Guilt subscore was negatively correlated with the subjective measure of sexual arousal for the heterosexual intercourse and forcible rape tapes.

Victim reactions in aggressive erotic films as a factor in violence against women.

Investigated whether the behavioral characteristics of the people in erotic films and the nature of the targets available for aggression afterward can affect subsequent aggression. In Exp I, 80 male undergraduates were angered by a male or female confederate. They were then shown a neutral film or 1 of 3 erotic films. The erotic films differed in terms of their aggressive content (2 were aggressive and 1 was not) and the reactions of the female victim in the 2 aggressive films (positive vs negative). Ss were then allowed to aggress against the confederate via electric shock. Results indicated that films had no effect on male targets, whereas both types of aggressive erotic films increased aggression toward the females. In Exp II with 80 male Ss, the effects of the above films on nonangry viewers were investigated with only female confederates. Results indicate that angered Ss were more aggressive toward the female after viewing either aggressive erotic film but that only the positive-outcome aggressive film increased aggression in nonangered Ss. The theoretical and applied aspects of aggressive and nonaggressive erotica are discussed. (40 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Sexual relationships, risk behaviour, and condom use in the spread of sexually transmitted infections to heterosexual men

Adolescents attending 5 state schools for the deaf responded to a 35-item questionnaire designed to probe their knowledge of AIDS. The 129 students in grades 9-12 had extremely limited core knowledge of AIDS, with the correct answers to only 8 of the 35 questions known by most students in all 4 grades. A minority of males and females knew the answers to most questions, indicating that AIDS education programs for deaf adolescents are urgently needed.     

Using cognitive science methods to assess the role of social information processing in sexually coercive behavior.

74 undergraduate men completed cognitive performance tasks assessing perceptual organization, classification, and category learning, as well as self-report measures relevant to sexual coercion. The stimuli were slides of Caucasian women who varied along affect and physical exposure (i.e., sensuality) dimensions. Data were analyzed using a weighted multidimensional scaling model, signal-detection theory analyses, and a connectionist learning model (RASHNL; J. K. Kruschke and M. K. Johansen, 1999). Individual differences in performance on the classification and category-learning tasks were congruent with individual differences in perceptual organization. Additionally, participants who showed relatively more attention to exposure than to affect were less sensitive to women's negative responses to unwanted sexual advances. Overall, the study demonstrates the feasibility and utility of cognitive science methods for studying information processing in psychopathology, (PsycINFO Database Record (c) 2010 APA, all rights reserved)
