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.     

Arousal transfer: The influence of fear arousal on subsequent sexual arousal for subjects with high and low sex guilt

Male subjects (N = 128) with high or low sex guilt either were or were not threatened with shock (fear arousal manipulation) and then viewed either an erotic or a neutral film (sex arousal manipulation). Then all subjects viewed and rated slides of attractive women and slides of landscapes (neutral control slides). If fear arousal was specifically transferred to sexual arousal as is often predicted rather than simply causing a general increase in arousal, then it would be expected that subjects who had been exposed to the threat would show high arousal in response to the slides of women and low arousal to the slides of landscapes, whereas subjects who had not been threatened would show low arousal to both the slides of women and landscapes. Physiological (pulse rate, skin resistance), self-report, and word association measures consistently indicated that (a) both of the arousal manipulations were effective, (b) the slides of women were arousing, (c) sex guilt influenced responses as would be expected from previous research, but (d) did not indicate support for arousal transference. These findings (a) provide information concerning the influence of guilt on drives, (b) raise questions about the transfer of arousal that was noted in less controlled investigations, and (c) highlight the need for additional controls in research of this type.     

The influence of sex and sex role orientation on sexual coercion

One hundred female and 77 male college students completed a questionnaire in which they indicated whether they had ever used physical or verbal coercive strategies to initiate sexual behavior with a partner, or had ever engaged in sexual behavior in response to a partner's coercive initiatives. Results showed that males are far more likely than females to initiate coerced sexual behavior and females are more likely to be victimized. In addition, masculine persons reported using coercive strategies more than other sex role orientation types. However, this was due principally to the fact that males were masculine types much more frequently than females. Therefore, sex (that is, being male or female) seems a more critical factor in determining, initiating, or responding to sexual coercion than sex role orientation.     

Effects of sex role identity and sex on definitions of sexual harassment

Individuals' own definitions of sexual harassment ultimately influence the success of their companies in responding to the Equal Employment Opportunity Commission's (EEOC) guidelines against sexual harassment. Previous research has consistently shown that women see more sexual harassment than do men. However, sex differences in definitions of sexual harassment could be explained by sex role identity. Results from a study of undergraduate business students and MBA students holding full-time jobs instead reaffirmed the existence of a sex effect and revealed the presence of a Sex X Masculinity interaction effect. Subjects' femininity had a minor effect on their definitions of sexual harassment.A previous version of this article was presented at the Academy of Management Meeting, Dallas, August, 1983. Appreciation is extended to Lisa A. Film for her assistance with data analysis.     

Causal attributions and male sexual arousal: the impact of attributions for a bogus erectile difficulty on sexual arousal, cognitions, and affect

After viewing 2 sexually explicit films, 52 sexually functional participants were given bogus feedback indicating a low erectile response. The men were given either an external, fluctuating attribution (i.e., poor films) or an internal, stable attribution (i.e., problematic thoughts about sex) for the low arousal. As hypothesized, participants in the external, fluctuating group evidenced greater erectile response and subjective arousal during a 3rd film than did participants given the internal, stable attribution. This may indicate that after an occasion of erectile difficulty, the cause to which the difficulty is attributed plays an important role in future sexual functioning.     

Irreplaceability and the intentionality of sexual arousal

Philosophers writing about the intentionality of sexual arousal have generally been of two minds. One approach likens it to an appetite that aims at a distinctive type of gratification. A second treats it as the attempt, through a process of embodiment, to unite with a transcendental self. The first model lays stress on the fungibility of the object of sexual desire: the body and certain of its parts. The latter sees arousal as burdened with impossible satisfaction conditions based on an extravagant metaphysics of the self. In this paper, I defend an account that emphasizes the cooperative element in arousal and assimilates its content to that of other such social activities. This preserves the central place of the self in the intentionality of arousal in a way that is metaphysically benign and that ultimately avoids treating sex as a sui generis form of human interaction.     

Adding fuel to fire: the impact of followers' arousal on ratings of charisma

The authors conducted an experimental laboratory study and a longitudinal field study to investigate the impact of followers' arousal on ratings of charisma. Both studies examined 2 contrasting hypotheses: (a) the misattribution hypothesis, which posits a direct effect of arousal, and (b) the response-facilitation hypothesis, which posits an interactive effect of arousal and leaders' charismatic appeal on ratings of charisma. The overall results from both studies provide support for the response-facilitation hypothesis. In addition, the authors tested the hypothesis that arousal effects are limited to ratings of charisma. As expected, ratings of transactional leadership, in contrast with ratings of charisma, were not influenced by followers' arousal states. The authors discuss the implications of these results and offer suggestions for future research.     

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.     

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.     

Early sexual experiences: the role of Internet access and sexually explicit material.

The current study investigated whether viewing X-rated movies, Internet access in the home, and gender of the participant would differ between age of first initiation for oral sex, age of first initiation for sexual intercourse, and number of sexual partners. An online sample of 437 participants with an average age of 29.46 participated in the study. Each participant completed a survey that assessed early sexual behaviors and Internet and X-rated material exposure. Results discovered males with Internet access during the ages of 12 to 17 reported significantly younger ages for first oral sex compared to males without Internet access. In addition, male and female participants with Internet access, between the ages 12 to 17, reported younger ages for first sexual intercourse compared to participants without Internet access. Study limitations and implications are discussed.     

Jealousy in response to online and offline infidelity: the role of sex and sexual orientation

The goal of the present study was to examine the emotional content and intensity of jealousy in response to different types of infidelity (both online and offline unfaithful partner behaviors) among Dutch heterosexuals (n = 191) and homosexuals (n = 121). Based on previous research (Dijkstra, Barelds & Groothof, 2010), participants were presented with ten jealousy‐evoking situations following which the intensity of two different emotional aspects of jealousy was assessed (betrayal/anger and threat). Results showed that scenarios describing a partner having sex with someone else or falling in love with someone else primarily evoked betrayal/anger‐related jealousy, whereas scenarios describing an emotional connection between a partner and someone else primarily evoked threat‐related jealousy. In addition, women experienced more jealousy than men in response to scenarios in which a partner engaged in potentially extra‐dyadic online (but not offline) behaviors. Finally, compared to same‐sex heterosexuals, homosexuals, both male and female, responded with less intense jealousy to scenarios describing a partner having sex with someone else. Implications for the treatment of (internet) infidelity are discussed.     

Pavlovian conditioning of sexual arousal: first- and second-order effects

Despite the likely importance of Pavlovian conditioning in sexual behavior, previous evidence of reliable or sizeable effects is very sparse. This report includes four experiments in the conditioning of sexual arousal in the males of a mammalian species, namely, the rat. In each case the unconditioned response (UR) was unconsummated arousal after exposure to a female. There was evidence of a substantial conditioned effect, as shown by decreases in the time to complete copulation during postconditioning conditioned stimulus (CS) tests. It is also possible to establish a second-order conditioned response (CR), which retains its strength even after extinction of the first-order response. These results confirm the power of Pavlovian contingencies in sexual responding and provide implications for conditioning theory and applied work.     

Distinct brain systems underlie the processing of valence and arousal of affective pictures

Valence and arousal are thought to be the primary dimensions of human emotion. However, the degree to which valence and arousal interact in determining brain responses to emotional pictures is still elusive. This functional MRI study aimed to delineate neural systems responding to valence and arousal, and their interaction. We measured neural activation in healthy females (N = 23) to affective pictures using a 2 (Valence) × 2 (Arousal) design. Results show that arousal was preferentially processed by middle temporal gyrus, hippocampus and ventrolateral prefrontal cortex. Regions responding to negative valence included visual and lateral prefrontal regions, positive valence activated middle temporal and orbitofrontal areas. Importantly, distinct arousal-by-valence interactions were present in anterior insula (negative pictures), and in occipital cortex, parahippocampal gyrus and posterior cingulate (positive pictures). These data demonstrate that the brain not only differentiates between valence and arousal but also responds to specific combinations of these two, thereby highlighting the sophisticated nature of emotion processing in (female) human subjects.     

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.
