A reproductive threat-based model of evolved sex differences in jealousy

Although heterosexual women and men consistently demonstrate sex differences in jealousy, these differences disappear among lesbians and gay men as well as among heterosexual women and men contemplating same-sex infidelities (infidelities in which the partner and rival are the same sex). Synthesizing these past findings, the present paper offers a reproductive threat-based model of evolved sex differences in jealousy that predicts that the sexes will differ only when the jealous perceivers' reproductive outcomes are differentially at risk. This model is supported by data from a web-based study in which lesbians, gay men, bisexual women and men, and heterosexual women and men responded to a hypothetical infidelity scenario with the sex of the rival randomly determined. After reading the scenario, participants indicated which type of infidelity (sexual versus emotional) would cause greater distress. Consistent with predictions, heterosexual women and men showed a sex difference when contemplating opposite-sex infidelities but not when contemplating same-sex infidelities, whereas lesbians and gay men showed no sex difference regardless of whether the infidelity was opposite-sex or same-sex.     

Minority stress and mental health among Dutch LGBs: examination of differences between sex and sexual orientation

Minority stress is often cited as an explanation for greater mental health problems among lesbian, gay, and bisexual (LGB) individuals than heterosexual individuals. However, studies focusing on sex or sexual orientation differences in level of minority stress and its impact on mental health are scarce, even more so outside the United States. Performing secondary analyses on the data of a Dutch population study on sexual health, the present study examines the robustness of the minority stress model by explaining mental health problems among men and women with mostly or only same-sex sexual attraction, and men and women who are equally attracted to same-sex and opposite-sex partners in the "gay-friendly" Netherlands (N = 389; 118 gay men, 40 bisexual men, 184 lesbian women, and 54 bisexual women). Results showed that minority stress is also related to mental health of Dutch LGBs. Participants with a higher level of internalized homonegativity and those who more often encountered negative reactions from other people on their same-sex sexual attraction reported more mental health problems. Such negative reactions from others, however, had a stronger link with mental health among lesbian/gay than among bisexual participants. Openness about one's sexual orientation was related to better mental health among sexual minority women, but not among their male counterparts. Suggestions for future research, implications for counseling, and other societal interventions are discussed.     

Relationships between Gender Role Attitudes, Role Division, and Perception of Equity among Heterosexual, Gay and Lesbian Couples

The purpose of the present study was to investigate the relationships between gender role attitudes, household tasks, and the perception of equity among heterosexual, gay and lesbian couples. One hundred and twenty-four participants (54 heterosexuals, 30 gay men and 40 lesbians) were tested. It was found that same-sex couples had more liberal attitudes toward gender roles than did heterosexual couples. In addition, significant differences were found between the spouses in their responses regarding role division in housekeeping in each group. The responses of heterosexual spouses correlate more closely with each other regarding the role of each of the spouses than was the case for same-sex couples. However, the role division among lesbian couples was more egalitarian than that of heterosexual couples. In addition, heterosexual women consider their married life less equitable than heterosexual men do. Similarly, one of the gay spouses considers the relationship less equitable than the other spouse does. The results are discussed in terms of their relevance to theories of social perception and cultural backgrounds.     

Adult romantic relationships as contexts of human development: a multimethod comparison of same-sex couples with opposite-sex dating, engaged, and married dyads

This article presents a multimethod, multi-informant comparison of community samples of committed gay male (n=30) and lesbian (n=30) couples with both committed (n=50 young engaged and n=40 older married) and noncommitted (n=109 exclusively dating) heterosexual pairs. Specifically, in this study the quality of same- and opposite-sex relationships was examined at multiple levels of analysis via self-reports and partner reports, laboratory observations, and measures of physiological reactivity during dyadic interactions. Additionally, individuals in same-sex, engaged, and marital relationships were compared with one another on adult attachment security as assessed through the coherence of participants' narratives about their childhood experiences. Results indicated that individuals in committed same-sex relationships were generally not distinguishable from their committed heterosexual counterparts, with one exception--lesbians were especially effective at working together harmoniously in laboratory observations.     

Money, Housework, Sex, and Conflict: Same-Sex Couples in Civil Unions, Those Not in Civil Unions, and Heterosexual Married Siblings

In this study we examined the division of finances, the division of household tasks, relationship maintenance behaviors, sexual activity, monogamy, and conflict among same-sex couples who had had civil unions in Vermont, same-sex couples who had not had civil unions recruited from their friendship circles, and married heterosexual couples recruited from among their siblings. Married heterosexuals had a more traditional, gendered division of finances, household tasks, and relationship maintenance behaviors, even though the heterosexuals were all siblings or in-laws of lesbians or gay men. Sexual orientation was a stronger predictor of the division of household tasks than was income difference within couples. Lesbians reported less frequent sexual activity than married heterosexual women, and gay men were less monogamous than married heterosexual men. Gay men in civil unions differed on a few variables from gay men not in civil unions, but there were no differences among lesbians.     

Gender differences in friendship patterns

The same-sex and opposite-sex friendship patterns of men and women students from two first-year psychology classes at the University of Waikato in New Zealand were examined. A friendship questionnaire previously used in the United States of America was administered to compare results of the two cultures. Findings from this study support American research suggesting that women are more intimate and emotional in their same-sex friendships than men, and tend to place a higher value on these friendships than men do. In accordance with findings of the American sample, New Zealand women emphasized talking, emotional sharing, and discussing personal problems with their same-sex friends, and men showed an emphasis on sharing activities and doing things with their men friends. Differences between the American and New Zealand samples were shown for men in the number of friends and the intimacy levels of these friendships. New Zealand men preferred numerous but less intimate same-sex friends, while women (as in the United States) showed a preference for a few, close, intimate same-sex friends. Men, in contrast to women, derived emotional support and therapeutic value more from their opposite-sex relationships than their same-sex friendships. Finally, more men than women stated they would not cancel an engagement with an opposite-sex friend in order to go out with a same-sex friend. Results are interpreted as suggesting a need for changes in the current socialization process of males who are taught to repress their emotions and form rather less intimate and possibly less beneficial same-sex friendships than women.     

Gender-role's attitude, perceived similarity, and sexual prejudice against gay men

Two hundred and twenty-six heterosexual participants (115 women and 111 men) were asked to indicate their attitude toward gender-roles, their perceived similarities with gay men, and their attitude toward gay men (i.e., sexual prejudice). As expected, male participants showed more sexual prejudice than female participants, and perceived dissimilarities were related to a greater sexual prejudice. Support for gender-roles was related to sexual prejudice for male participants, but not for female participants. More interestingly, the three-way interaction suggested that perceived similarities moderated the link between gender-roles and sexual prejudice among heterosexual men, but not among heterosexual women. Attitude in favor of traditional gender-roles was related to sexual prejudice for male participants who perceived gay men as different, but not for those who perceived gay men as similar. These findings are discussed in terms of the defensive function of men's attitude toward homosexuality as a result of threat to masculinity.     

Sexual Debut Ages in Heterosexual,Lesbian, Gay,and Bisexual Young Adults in Norway

This study estimates sexual debut ages in young heterosexual, lesbian, gay, and bisexual men and women in Norway. A questionnaire survey was completed online by 27.2 % of a representative national web sample of 2090 persons aged 18–29 years. Three self-selected samples of 924 respondents completed an extended version of the survey online. Lesbian and bisexual women reported earlier experience of orgasm through masturbation than heterosexual women (median 13.1 vs. 15.2 years), and heterosexual men (median 13.5) reported earlier debut than heterosexual women. There was a statistically significant difference between heterosexual and lesbian and bisexual women’s age at the first experience of receptive vaginal sex (median 16.8 vs. 15.4 years). As regards experience of insertive vaginal sex, a significantly higher percentage of heterosexual men than women, and of heterosexual and lesbian and bisexual women, reported experience. It was more common among lesbian and bisexual women than heterosexual women to have had oral sex with another woman, but in neither group did the cumulative percent reach 50 % by the age of 29 years and the median could not be estimated. Gay and bisexual men reported earlier receptive anal sex debut than heterosexual men. With regard to insertive anal sex, gay and bisexual men accumulated experience earlier than heterosexual men, and lesbian and bisexual women acquired this experience earlier than heterosexual women. Compared to heterosexuals, LGB persons of both genders engage in more varied sexual activities. Lesbian and gay persons have same-sex experiences at an earlier age than bisexuals.     

Masculinity Ideology, Male Identity, and Romantic Relationship Quality Among Heterosexual and Gay Men

This research assessed factors that may affect men’s romantic relationships. One hundred men (50 heterosexual and 50 gay) in the Northeast US completed measures that assessed masculinity ideology, male identity, and relationship quality. We examined whether the quality of heterosexual men’s romantic relationships differ from that of romantic relationships among gay men, and whether masculinity ideology and male identity are related to the quality of heterosexual and same-sex romantic relationships. Results indicated no differences between heterosexual and gay men in the perceived quality of romantic relationships. However, in both gay and heterosexual men, traditional masculinity ideology and a male identity characterized by a lack of psychological relatedness to other men were associated with lower quality romantic relationships.     

Does body satisfaction differ between gay men and lesbian women and heterosexual men and women? A meta-analytic review

Studies investigating body image satisfaction among groups of different sexual orientations (i.e., gay men, lesbian women, and heterosexual men and women) have produced equivocal findings. To synthesise the available research, 27 studies (20 published and 7 unpublished) were meta-analysed (N=5220). Comparisons between heterosexual (n=1397) and gay men (n=984) produced a small effect size, with the former being slightly more satisfied with their bodies. An even smaller difference was observed for studies comparing heterosexual (n=1391) and lesbian women (n=1448), with greater levels of body satisfaction being evidenced by the latter group. Tests of homogeneity for each effect size were found to be highly significant. In an attempt to identify variables that may be responsible for the observed heterogeneity, the following categorical factors were assessed: the measures used to evaluate body satisfaction, date of study (1980s versus 1990s+), publication status (published or unpublished), and body weight. The results of this exploratory search for potential moderator variables as well as limitations of the current meta-analysis are discussed.     

Gay and lesbian coaches' teams: differences in liking by male and female former sport participants

Previous literature suggests that men, more than women, both adhere to traditional gender beliefs and evaluate violators more harshly. Thus, within the heteronormative sport environment it was hypothesized that men's liking of a team coached by a gay or lesbian may be influenced more than women's liking. Respondents were college-age men (n=130) and women (n=98), former sport participants. Multivariate analysis of covariance (controlling for the presence of gay and lesbian friends and acquaintances) supported the hypothesis. Findings are discussed in terms of sports' heterosexual environment, adherence to gender-role norms, and motivational sexual prejudice.     

Beyond Similarities: Cross-Gender and Cross-Orientation Best Friendship in a Sample of Sexual Minority and Heterosexual Young Adults

The research investigates differences between heterosexual (n?=?714) and lesbian and gay men (n?=?386) young adults regarding best friendship patterns, well-being, and social anxiety. Based on data from a paper-pencil survey of 1,100 Italian young adults aged 18 to 26, this study underlines the importance of the best friend in young adults’ psychological adjustment, highlighting patterns of friendship in heterosexual and lesbian and gay men young adults. Overall, the majority of participants declared that they had best friends; in the total sample, significant differences were found between women and men, and between lesbian/gay men participants and heterosexual young adults. Lesbian and gay men participants reported more cross-gender best friendships than heterosexual participants did, as well as more cross-orientation best friendships. Gender differences were found only with regards to cross-gender friendships: gay men reported more cross-gender friendships than lesbians did, while heterosexual females reported a higher percentage of cross-gender best friendship than heterosexual males did. MANOVA analysis, only in the gay and lesbian sample, showed the effect of gender, cross-gender, and cross-orientation on well-being and social anxiety. For the well-being dimension, gay men participants with female best friends reported higher scores. In terms of social anxiety, lesbian and gay young adults with cross-gender and cross-orientation best friends reported lower levels of social anxiety.     

Sexual willingness with same- and other-sex prospective partners: Experimental evidence from the bar scene

Sex is ubiquitous in the media, but only a fraction depicts sexual interactions between same-sex partners. This field study, conducted outside of bars in the Midwestern United States, examined 83 heterosexuals’ sexual willingness with a same- or other-sex partner. Participants viewed a randomly assigned video vignette of a same- or other-sex partner. Alcohol intake, partner attractiveness, and sexual willingness were measured. Using moderated regression analysis, we found that alcohol intake predicted sexual willingness with the male target for both men and women, but not with the female target. The attractiveness of same-sex partners was related to sexual willingness. Sexual willingness was only influenced by alcohol intake and perceived attractiveness of a same-sex prospective partner. Most notably, alcohol intake was related to increased sexual willingness of men with a same-sex partner, suggesting a potential shift in normative casual sexual behavior among heterosexual men.     

An exploration of prevalence of domestic violence in same-sex relationships

The prevalence of domestic violence in a sample of 33 men and 33 women currently or previously in same-sex relationships was assessed. Data were collected through a mail survey in the state of Virginia. Of 1000 surveys sent out 66 usable ones were returned (response rate = 6.6%). Analysis indicated that 34 had experienced some form of domestic violence, but significant differences between male and female respondents were not detected. When data from this same-sex sample were compared with those of the heterosexual sample of the National Violence Against Women Survey, intimate partner assault may be more prevalent against gay men than against heterosexual men, but there was no significant difference between lesbians and heterosexual females.     

Beauty and the attributions of the beholder

Four studies used an attributional approach to examine interpersonal attraction. Underlying causal dimensions were predicted to influence differentially two components of attraction, dating and complimenting. In the first study, 24 subjects indicated whether they would date physically attractive stimulus persons. Complimenting was examined in the second and third studies, with 24 subjects rating the likelihood of complimenting attractive opposite-sex stimulus persons and 32 subjects rating the likelihood of complimenting same-sex stimulus persons. For these studies the reason for the stimulus person's attractiveness varied in controllability (volitional versus nonvolitional) and stability (temporary versus permanent). Consistent with predictions, controllability influenced likelihood of complimenting but not dating. In addition, compliments were more likely when the reason for attractiveness was unstable than when stable. Conversely, dating was more likely when attactiveness was stable than when unstable. However, stability had less influence on men responding to women than on either men responding to men or women responding to both sexes. Similar results were obtained in a fourth study in which 56 subjects recalled incidents where they complimented or dated others for their physical attractiveness.     

Toward an Understanding of “The Sex Game”: The Effects of Gender and Self-Monitoring on Perceptions of Sexuality and Likability in Initial Interactions1

Results of several studies indicate that men attribute more sexual meaning to heterosexual interactions than do women. Based on Abbey's (1982) findings, we hypothesized that males, in comparison to females, would attribute more sexuality to opposite-sex partners. Based on findings from several self-monitoring dating studies, we predicted that high self-monitors would rate their partners and themselves higher on sexuality and likability traits than would low self-monitors. A laboratory study was conducted in which mixed-sex pairs of participants discussed their likes and dislikes about college life. Participants then rated themselves and their opposite-sex partners on a set of sexuality and likability trait adjectives and indicated their interest in getting to know their partner better. Results supported the gender hypotheses, whereas they only partially supported the self-monitoring predictions. The self-monitoring effects on self-ratings of sexuality and partner ratings of likability are used to explain why high self-monitors are more successful than low self-monitors in establishing heterosexual relationships.     

Gender differences in the incentive salience of adult and infant faces

Facial appearance can motivate behaviour and elicit activation of brain circuits putatively involved in reward. Gender differences have been observed for motivation to view beauty in adult faces—heterosexual women are motivated by beauty in general, while heterosexual men are motivated to view opposite-sex beauty alone. Although gender differences have been observed in sensitivity to infant cuteness, infant faces appear to hold equal incentive salience among men and women. In the present study, we investigated the incentive salience of attractiveness and cuteness in adult and infant faces, respectively. We predicted that, given alternative viewing options, gender differences would emerge for motivation to view infant faces. Heterosexual participants completed a “pay-per-view” key-press task, which allowed them to control stimulus duration. Gender differences were found such that infants held greater incentive salience among women, although both sexes differentiated infant faces based on cuteness. Among adult faces, men exerted more effort than women to view opposite-sex faces. These findings suggest that, contrary to previous reports, gender differences do exist in the incentive salience of infant faces as well as opposite-sex faces.     

Gender-related traits in gay men, lesbian women, and heterosexual men and women: the virtual identify of homosexual-heterosexual diagnosticity and gender diagnosticity

Three studies investigated the relationship between gender-related traits and sexual orientation. Study 1 showed that gay men and lesbians in an unselected sample of 721 college students differed from same-sex heterosexuals most strongly on gender diagnosticity (GD) measures, which assess male- versus female-typicality of interests (effect sizes of 2.70 for men and .96 for women) and least strongly on measures of instrumentality (I) and expressiveness (E). In Study 2, GD measures showed large differences between 95 gay and 136 heterosexual men (effect sizes of 1.61 and 1.83) and between 46 lesbian and 225 heterosexual women (effect sizes of .98 and 1.28), whereas I and E showed much smaller differences. In Study 3, GD showed large differences between 90 gay and 81 heterosexual men (effect sizes of 1.76 and 1.97) and between 82 lesbians and 108 heterosexual women (effect sizes 1.67 and 1.70). whereas I and E showed much smaller differences. Using data from Studies 2 and 3, "gay-heterosexual diagnosticity" measures were computed for men and "lesbian-heterosexual diagnosticity" measures for women, based on occupational and hobby preferences. These measures correlated very strongly with GD measures.     

The Effect of Self‐Identified Sexual Orientation on Helping Behavior in a British Sample: Are Lesbians and Gay Men Treated Differently?

In a British sample, the wrong-number technique was used to examine levels of helping behavior shown toward lesbians and gay men. A wrong-number telephone call, from either a man who self-identified as gay or heterosexual, or a woman who self-identified as either lesbian or heterosexual, was made to 232 men and women. The caller requested help by asking the respondent to relay a message to his or her partner by telephone. As predicted, lesbians and gay men were less likely to be given help than were their same-gender heterosexual counterparts. However, lesbians were given a similar amount of help as were heterosexual men. Male participants were less likely to give help to gay men than to lesbians, but female participants were no less likely to help lesbians than gay men. The results suggest that, although lesbians and gay men meet discrimination in everyday life, the level of discrimination may differ.     

Employee Gender, Gender Similarity, and Supervisor-Subordinate Cross-Evaluations

This article examines the relationship between employee gender and gender similarity on the one hand and supervisor-subordinate cross-evaluations and subordinate rewards on the other, using a sample of 651 employees from five midwestern organizations. Data were obtained through structured interviews, supervisor ratings of subordinates, and employee personnel records. Two-way analysis of variance results indicated that (a) evaluations of women are more positive than evaluations of men and (b) opposite-sex evaluations tend to be higher than same-sex evaluations, but (c) men subordinates receive more promotions, and same-sex subordinates more pay increases, than do women subordinates and opposite-sex subordinates respectively.
