The effect of stimulus content on volunteering for sexual interest research among college students

Much of the literature on volunteer bias in sexual interest research has been limited to either identifying variables on which volunteers differ from nonvolunteers or examining how the intrusiveness of the meaurement device affects volunteer rates. The present study was designed to examine whether stimulus content would affect volunteer rates and volunteer/non‐volunteer differences in a large sample of college students (206 men and 358 women). The study also sought to determine whether such findings could also apply to research that recruits from exclusively heterosexual samples. Students completed questionnaires in small groups and were asked whether they would be willing to volunteer for studies that would involve viewing and rating five different types of sexually explicit images (nude men, nude women, heterosexual behavior, male homosexual behavior, and female homosexual behavior). Results indicate that men and women differed in the types of images that they would volunteer to view, based upon the content of the images. Furthermore, volunteers for each type of image reported significantly greater self‐monitoring as well as sexual and general sensation seeking than did nonvolunteers, while differences on other measures were less consistent. Discussion is given to specific ways in which the findings and gen‐eralizability of sexual interest study results can be affected.     

Individual Differences in the Effects of Mood on Sexuality: The Revised Mood and Sexuality Questionnaire (MSQ-R)

Previous research using the Mood and Sexuality Questionnaire (MSQ) has revealed substantial variability in how negative mood impacts sexual response and behavior. However, the MSQ does not address differences between desire for solo or partnered sexual activity, examine the effects of sexual activity on mood, or assess the effects of positive mood. This article presents the development and factor structure of the Revised Mood and Sexuality Questionnaire (MSQ-R). An exploratory factor analysis in a sample of heterosexual men, homosexual men, and heterosexual women (N = 1,983) produced eight factors. Considerable variability was found in how moods influence sexual desire and arousal, in the effects of mood on sexual behavior, and in the reciprocal effects of sexual activity on mood. Among other findings, heterosexual women were less likely than heterosexual men and homosexual men to experience increased sexual desire and arousal when anxious or stressed, whereas homosexual men and heterosexual women were less likely than heterosexual men to experience increased desire when sad or depressed. Heterosexual men and heterosexual women were more likely than homosexual men to report increased desire when in a positive mood. Intercorrelations and correlations with various sexual behaviors varied by group. Limitations and implications of the findings are discussed.     

Heterosexual,Homosexual, and Bisexual Men’s Pupillary Responses to Persons at Different Stages of Sexual Development

This study investigated whether pupil size during the viewing of images of adults and children reflects the sexual orientation of heterosexual, homosexual, and bisexual men (n = 100, M_age = 22). More specifically, we explored whether this measure corresponds with sexual age preferences for adults over children in nonpedophilic men. In general, results across three experiments, in which observers freely viewed or rated the sexual appeal of person images, suggest that pupil dilation to sexual stimuli is an indicator of sexual orientation toward adults. Heterosexual men’s pupils dilated most strongly to adults of the other sex, homosexual men dilated most strongly to adults of the same sex, and bisexual men showed an intermediate pattern. Dilation to adults was substantially stronger than dilation to younger age groups. Sexual appeal ratings for images of adults and children also correlated with pupil responses, suggesting a direct link between pupil dilation and sexual interest. These findings provide support for pupil dilation as a measure of sex- and age-specific sexual preferences.     

Androgen and psychosexual development: core gender identity, sexual orientation and recalled childhood gender role behavior in women and men with congenital adrenal hyperplasia (CAH)

We assessed core gender identity, sexual orientation, and recalled childhood gender role behavior in 16 women and 9 men with CAH and in 15 unaffected female and 10 unaffected male relatives, all between the ages of 18 and 44 years. Women with congenital adrenal hyperplasia (CAH) recalled significantly more male-typical play behavior as children than did unaffected women, whereas men with and without CAH did not differ. Women with CAH also reported significantly less satisfaction with the female sex of assignment and less heterosexual interest than did unaffected women. Again, men with CAH did not differ significantly from unaffected men in these respects. Our results for women with CAH are consistent with numerous prior reports indicating that girls with CAH show increased male-typical play behavior. They also support the hypotheses that these women show reduced heterosexual interest and reduced satisfaction with the female sex of assignment. Our results for males are consistent with most prior reports that boys with CAH do not show a general alteration in childhood play behavior. In addition, they provide initial evidence that core gender identity and sexual orientation are unaffected in men with CAH. Finally, among women with CAH, we found that recalled male-typical play in childhood correlated with reduced satisfaction with the female gender and reduced heterosexual interest in adulthood. Although prospective studies are needed, these results suggest that those girls with CAH who show the greatest alterations in childhood play behavior may be the most likely to develop a bisexual or homosexual orientation as adults and to be dissatisfied with the female sex of assignment.     

Fraternal Birth Order,Handedness, and Sexual Orientation in a Chinese Population

We examined the relationship between handedness, fraternal birth order, and sexual orientation in a Chinese population, and analyzed the influence of the components assessing sexual orientation and criteria classifying individuals as homosexual on this relationship. A large sample of heterosexual, bisexual, and homosexual men and women participated in a web-based survey. Our results showed that homosexual women are more likely to be non-right-handed than heterosexual women, regardless of how sexual orientation was defined, whereas bisexual women are more likely to be non-right-handed than heterosexual women when sexual orientation was assessed via sexual attraction and sexual identity. Bisexual men are more likely to be non-right-handed than heterosexual men when sexual orientation was assessed via sexual attraction. We found neither a fraternal birth-order effect nor an interaction between sibling sex ratio, handedness, and sexual orientation. The small number of siblings may be the reason why we could not replicate the fraternal birth-order effect in this Chinese population, which highlights the importance of cultural differences in the understanding of handedness, fraternal birth order, and sexual orientation.     

Women's Erotic Rape Fantasies: An Evaluation of Theory and Research

In an online study, measures of subjective sexual experiences in one's current relationship were compared across four groups: Men and women in mixed-sex (i.e., heterosexual) and same-sex (i.e., homosexual) relationships. Results indicated far more similarities than differences across the four groups, with groups reporting almost identical sexual repertoires, and levels of sexual communcation with partner. Men reported experiencing somewhat more sexual desire than women, while women reported slightly higher levels of general sexual satisfaction than men. Those in same-sex relationships reported slightly higher levels of sexual desire than those in mixed-sex relationships. Compared to the other three groups, heterosexual men reported deriving somewhat less satisfaction from the more tender, sensual, or erotic sexual activities. Implications of these findings for sex therapists are discussed.     

Heterosexuals attitudes toward bisexual men and women in the United States

This paper examines heterosexual adults attitudes toward bisexual men and women using data from a 1999 national RDD survey (N = 1,335). Ratings on 101-point feeling thermometers were lower (less favorable) for bisexual men and bisexual women than for all other groups assessed--including religious, racial, ethnic, and political groups--except injecting drug users. More negative attitudes toward bisexuals were associated with higher age, less education, lower annual income, residence in the South and rural areas, higher religiosity, political conservatism, traditional values concerning gender and sexual behavior, authoritarianism, and lack of contact with gay men or lesbians. White heterosexual women expressed significantly more favorable attitudes than other women and all men. A gender difference was observed in attitudes toward bisexuals and homosexuals: Heterosexual women rated bisexuals significantly less favorably than they rated homosexuals, regardless of gender, whereas heterosexual men rated male targets less favorably than female targets, regardless of whether the target was bisexual or homosexual.     

Swinging: A replication and test of a theory

Traditional sex‐role stereotypes suggest that men and women engage in sex for different reasons. Previous studies have supported the notion that women are more motivated by emotional expression in having sex, and men are more concerned with physical gratification. In a survey of sexual behavior, heterosexual and homosexual respondents were asked to rate the importance of a variety of reasons for having sex and not having sex. The results showed that men and women differed in the importance attached to emotional and physical motives, with gender differences appearing in both heterosexuals and homosexuals. Certain practical motives (e.g., to reproduce, fear of AIDS, fear of pregnancy) differentiated between homosexuals and heterosexuals. Motivations predicting frequency of sexual behavior in the last month depended on the relationship status of the respondent. These findings, although suggesting that gender differences in motivations for sex persist in all kinds of relationships, point to many similarities among gay and straight men and women in reasons for having sex and limiting sexual activity.     

Differences in perceived barriers to volunteering to formal organizations: Lack of time versus lack of interest

This article reports the findings of a study of perceived barriers to volunteering to formal organizations by nonvolunteers. We examine the types of barriers, their frequencies, and their relationships with individual‐level sociodemographic characteristics of nonvolunteers. Data from a 2001–2002 national survey conducted by the U.S. Bureau of Labor Statistics are analyzed using multiple regression techniques. Contrary to general expectations, only three barriers—lack of time, lack of interest, and ill health—are fairly common. Furthermore, as expected, different social class groups identify different types of barriers. The article concludes with a discussion of the theoretical implications of the findings (for example, how indicators of social and cultural capital affect access to volunteer opportunities) and practical implications concerning recruitment of volunteers.     

Heterosexuals' attitudes toward bisexual men and women in the United States

This paper examines heterosexual adults’ attitudes toward bisexual men and women using data from a 1999 national RDD survey (N = 1,335). Ratings on 101‐point feeling thermometers were lower (less favorable) for bisexual men and bisexual women than for all other groups assessed—including religious, racial, ethnic, and political groups—except injecting drug users. More negative attitudes toward bisexuals were associated with higher age, less education, lower annual income, residence in the South and rural areas, higher religiosity, political conservatism, traditional values concerning gender and sexual behavior, authoritarianism, and lack of contact with gay men or lesbians. White heterosexual women expressed significantly more favorable attitudes than other women and all men. A gender difference was observed in attitudes toward bisexuals and homosexuals: Heterosexual women rated bisexuals significantly less favorably than they rated homosexuals, regardless of gender, whereas heterosexual men rated male targets less favorably than female targets, regardless of whether the target was bisexual or homosexual.     

Using Electronic Contact to Reduce Homonegative Attitudes,Emotions, and Behavioral Intentions Among Heterosexual Women and Men: A Contemporary Extension of the Contact Hypothesis

The current study experimentally examined the potential for a contemporary extension of the contact hypothesis, known as electronic contact, or E-contact, to reduce sexual prejudice, intergroup anxiety, and avoidant behavioral intentions among heterosexuals. It also extended the sexual minority contact literature by examining the role of participant and interaction partner sex as a possible boundary condition of this contact–prejudice relationship. To test our hypotheses, 140 heterosexual female and male university students were randomly allocated to interact with a homosexual or heterosexual, female or male E-contact partner, in a collaborative and text-only online interaction before completing the outcome measures. Overall, the results demonstrated that interacting online with a female, as opposed to a male, homosexual E-contact partner reduced heterosexual men’s feelings of intergroup anxiety, which in turn was associated with lower sexual prejudice and outgroup avoidance. For heterosexual women, however, E-contact did not influence the outcome variables. In the context of sexual prejudice, these results suggest that E-contact may be particularly useful as a prejudice-reduction strategy among individuals who typically require it most: heterosexual men.     

Pupillary Responses to Static Images of Men and Women: A Possible Measure of Sexual Interest?

The pupil dilates to images that are arousing. In Experiment 1, we examined if the pupil’s response to brief presentations (2,000 ms) of static images could be used to identify individuals’ sexual orientation. Participants were grouped according to their self-reported gender and sexual orientation (male heterosexual, N = 20; male bisexual, N = 13; male homosexual, N = 19; female heterosexual, N = 28; female bisexual, N = 21; female homosexual, N = 17). Pupil size was monitored to images of men in seminude poses, women in seminude poses, or neutral images. Every group showed the same pattern of responses, with the greatest dilation to male images, then female images, and least dilation to the neutral images. Experiment 2 used more tightly controlled stimuli and tested at two different image durations (150 and 3,000 ms). Both heterosexual men (N = 18) and women (N = 20) showed greater pupil dilation to images of nude men than to nude women. However, in Experiment 3, where we reduced the erotic content by using images of clothed models, both heterosexual men and women showed greater pupil dilation to images of women. The results showed that while the pupil does dilate strongly to sexual imagery, its response to these brief static images does not correspond to a person’s sexual orientation in a simple manner.     

Psychiatric Symptoms and Same-Sex Sexual Attraction and Behavior in Light of Childhood Gender Atypical Behavior and Parental Relationships

This study explores the relation between the level of current symptoms of depression and anxiety and recalled childhood gender atypical behavior (GAB), and quality of relationships with parents among men and women who reported same-sex sexual attraction or engaged in same-sex sexual behavior and men and women who did not. Matched pairs, 79 men (n = 158) and 148 women (n = 296), with equal levels of GAB were created of Finnish participants with either same-sex sexual attraction or behavior and participants without. The measures used were retrospective questionnaires. Ratings of maternal and paternal over-control and coldness differed as a function of same-sex sexual attraction or behavior. Childhood GAB was correlated with negative ratings of parental relationships. Both same-sex sexual attraction or behavior and a history of childhood GAB affected the reported levels of current depression and anxiety. Only gender typical participants with no same-sex sexual attraction or behavior reported significantly lower levels of symptoms. The findings suggest that childhood GAB is related to later distress both among hetero- and homosexual individuals. The elevated level of psychological distress among homosexual individuals, reported in several studies, might—to some extent—be caused by their generally higher levels of childhood GAB as opposed to a homosexual orientation per se.     

Attitudes toward lesbians,gay men,bisexual women,and bisexual men in Germany

Attitudes toward lesbians, gay men, bisexual women, and bisexual men were assessed in a national representative sample of 2,006 self‐identified heterosexual women and men living in Germany. Replicating previous findings, younger people held more favorable attitudes than older people; women held more favorable attitudes than men; and men held more favorable attitudes toward female than male homosexuality, whereas women did not differentiate. However, women held more favorable attitudes toward homosexuals than toward bisexuals, whereas men did not differentiate. Knowing a homosexual person was an important predictor of attitudes, as was political party preference. Both same‐sex and opposite‐sex sexual attraction were substantially related with attitudes. Our findings support the notion that attitudes toward lesbians, gay men, bisexual women, and bisexual men are related but distinct constructs.     

Does Sexual Orientation Have an Impact on Nonverbal Behavior in Interpersonal Communication?

This study explores the impact of sexual orientation on the nonverbal behavior of individuals in dyadic communication situations. It is hypothesized that the patterns of nonverbal behavior displayed in dyads with and without an individual with an open homosexual orientation are different from those in dyads with heterosexual participants only. An observational study was conducted with a total of 24 participants, 12 with a heterosexual orientation and 12 with a homosexual orientation (6 males and 6 females in each group). Participants were videotaped during a 20-min conversation which took place in dyads that were composed of individuals of the same biological sex with either the same sexual orientation (homosexual or heterosexual) or differing sexual orientations. Results show that in dyads which include a homosexual person nonverbal behavior is different from that displayed in dyads consisting of heterosexual participants only in terms of self-touch, body posture, body orientation, and gaze. Results are interpreted in terms of stereotyping and presentation rules.     

Attitudes toward lesbians, gay men, bisexual women, and bisexual men in Germany

Attitudes toward lesbians, gay men, bisexual women, and bisexual men were assessed in a national representative sample of 2,006 self-identified heterosexual women and men living in Germany. Replicating previous findings, younger people held more favorable attitudes than older people; women held more favorable attitudes than men; and men held more favorable attitudes toward female than male homosexuality, whereas women did not differentiate. However, women held more favorable attitudes toward homosexuals than toward bisexuals, whereas men did not differentiate. Knowing a homosexual person was an important predictor of attitudes, as was political party preference. Both same-sex and opposite-sex sexual attraction were substantially related with attitudes. Our findings support the notion that attitudes toward lesbians, gay men, bisexual women, and bisexual men are related but distinct constructs.     

Intimate partner homicide methods in heterosexual, gay, and lesbian relationships

Previous research indicates that the killing method used in homicides may reflect the motivation of the offender and qualities of the victim-offender relationship. The effect of gender and sexual orientation of intimate partner homicide offenders (N = 51,007) was examined with respect to the brutality of killing methods. Guided by previous research and theory, it was hypothesized that homicide brutality will vary with the offender's sexual orientation and gender, such that the percentage of killings coded as brutal will be higher for (a) gay and lesbian relative to heterosexual relations, (b) men relative to women, (c) gay relative to heterosexual men, and (d) lesbian relative to heterosexual women. The rates of intimate partner homicide were also hypothesized to vary with the gender of the partners, such that (a) homicide rates will be higher in gay relative to heterosexual and lesbian couples and (b) homicide rates will be lowest in lesbian couples. The results support all but one prediction derived from the two hypotheses. We predicted that men would kill their partners more brutally than would women, but the results indicate that the opposite is true.     

Traversing gender,sexual orientation,and race-ethnicity: Sexual victimization in a population-based sample of older adults

This research examined the intersectionality of gender, sexual orientation, and race-ethnicity, and its impact on lifetime sexual victimization among a population-based sample of older adults. Data for this study came from the 2011–2014 waves of the Behavioral Risk Factor Surveillance System. The final sample to be used for analysis included 8.862 individuals ages 50 years and over to examine whether and to what extent lesbian, gay, and bisexual older adults differ from heterosexual older adults in experiencing lifetime sexual victimization, and whether the effect of sexual orientation on experiencing lifetime sexual victimization differs across racial-ethnic groups. Logistic regression analysis revealed that lesbian women were 2.59 times more likely and bisexual women 2.15 times more likely both relative to heterosexual women to experience lifetime sexual victimization. When examining whether race-ethnicity imparts additional risk, the findings revealed that non-White heterosexual individuals were 29.6% less likely relative to White heterosexual individuals to experience lifetime sexual victimization, while non-White women, generally, were 2.29 times more likely relative to White men to experience lifetime sexual victimization. Our findings affirm the importance of the intersectionality of sexual orientation and gender when examining lifetime sexual victimization of older adults, adding to the emerging body of research that examines the complexities of older adult lives from multifaceted perspectives.     

Differential gaze behavior towards sexually preferred and non-preferred human figures

The gaze pattern associated with image exploration is a sensitive index of our attention, motivation, and preference. To examine whether an individual's gaze behavior can reflect his or her sexual interest, this study compared gaze patterns of young heterosexual men and women (M?=?19.94 years, SD?=?1.05) while they viewed photographs of plain-clothed male and female figures aged from birth to 60 years old. The analysis revealed a clear gender difference in viewing sexually preferred figure images. Men displayed a distinctive gaze pattern only when viewing 20-year-old female images, with more fixations and longer viewing times dedicated to the upper body and waist-hip regions. Women also directed more attention at the upper body on female images in comparison to male images, but this difference was not age-specific. Analysis of local image salience revealed that observers' eye-scanning strategies could not be accounted for by low-level processes, such as analyzing local image contrast and structure, but were associated with attractiveness judgments. The results suggest that the difference in cognitive processing of sexually preferred and non-preferred figures can be manifested in gaze patterns associated with figure viewing. Thus, eye-tracking holds promise as a potential sensitive measure for sexual preference, particularly in men.
