Preference for human body odors is influenced by gender and sexual orientation

Human body odor may contribute to selection of partners. If so, sexual orientation may influence preference for and perhaps production of human body odors. In a test of these hypotheses, heterosexual and homosexual males and females made two-alternative forced-choice preference judgments for body odors obtained from other heterosexual and homosexual males and females. Subjects chose between odors from (a) heterosexual males and gay males, (b) heterosexual males and heterosexual females, (c) heterosexual females and lesbians, and (d) gay males and lesbians. Results indicate that differences in body odor are detected and responded to on the basis of, in part, an individual's gender and sexual orientation. Possible mechanisms underlying these findings are discussed.     

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.     

Sex role self schema and psychological adjustment in coupled homosexual and heterosexual men and women

This study examined the relation between dimensions of sex role self schema (assessed by four factor scores of the Bem Sex Role Inventory: Instrumentality, Expressiveness, Autonomy, and Masculinity-Femininity) and psychological adjustment (assessed by the Symptom Checklist-90-R) in 366 homosexuals (230 males and 136 females) and 241 heterosexuals (124 males and 117 females). All subjects were in a cohabitating relationship. Homosexuals and heterosexuals did not differ in psychological adjustment, but men were found to be more distressed by paranoid symptoms than women. Dimensions of sex role self schema varied by an interaction between gender and sexual orientation. Gender differences on Instrumentality, Expressiveness, and Masculinity-Femininity were more pronounced for heterosexuals than for homosexuals. Further, homosexual women were more Instrumental than heterosexual women, while homosexual and heterosexual men were equivalent; homosexual men were more Expressive than heterosexual men, while homosexual and heterosexual women were equivalent; and the discrepancy between homosexual and heterosexual women's Masculinity-Femininity score was greater than that between homosexual and heterosexual men. Hierarchical regression analyses indicated that only education and the Autonomy dimension of sex role self scheme were the best nonredundant predictors of psychological adjustment, although the relations were weak. Findings are discussed in terms of current theory and research on sex role self schemas.     

IS SEXUAL ORIENTATION A MATTER OF CHOICE?

Ninety women in lesbian and heterosexual couples were compared on relationship values, views of same-gender and cross-gender intimate relationships, and perceived choice of sexual orientation. Both groups reported similar values, levels of self-esteem, and capacity for intimacy. The majority in both groups described their relationships with women as more emotionally and intellectually intimate than those with men. A majority of women in lesbian couples (58%) and a third of women in heterosexual couples reported choosing the orientation of their current sexual relationship. Women with male partners did not perceive major differences between homosexual and heterosexual relationships, citing sexual attraction as the primary reason they chose a male partner. In contrast, many women with female partners characterized lesbian relationships as more intimate and equal, and less gender-role stereotyped, frequently citing these characteristics, along with sexual attraction, as reasons for their relationship preference.     

Sex differences in cognition: the role of testosterone and sexual orientation

The performance of both heterosexual and homosexual males and females was compared on four cognitive tasks which have been shown to reveal evidence of sexual dimorphism. In one spatial and one verbal task, significant sex and orientation effects were found. Significant relationships were also found between salivary free-testosterone levels and performance on both spatial tasks, but no significant associations were found for performance on the two verbal tasks. The present study revealed both within- and between-sex differences in cognition and indicates that these differences may be partly accounted for by the activational effects of free testosterone.     

Courtship in the personals column: The influence of gender and sexual orientation

Eight hundred personal advertisements were analyzed, representing an equal sampling of male and female homosexual and heterosexual advertisers on the East and West Coast of the United States. In general, men were more concerned with physical characteristics, while women stressed psychological factors. Homosexuals were more concerned with sexuality, while heterosexuals specified a broader range of characteristics. Significant interactions between gender and sexual orientation point to the importance of sex-role expectations in the heterosexual context and suggest substantial differences between males and females who choose homosexuality.     

Sexual orientation and visuo-spatial ability

On the basis of a literature review it was concluded that sex differences in cognitive ability and the etiology of male homosexuality may have a common biological base, leading to the prediction that in terms of cognitive ability homosexual males (HmM) would resemble heterosexual females (HtF) rather than heterosexual males (HtM). This prediction was investigated using visuo-spatial tasks on which males are known to perform better than females. In Experiment 1 HtM performed better on a water level task than HmM and HtF whose performances did not differ significantly. A different version of the water level task and the Vincent Mechanical Diagrams Test were used in Experiment 2; on both tasks the HtM performed better than the HmM and the HtF whose performance did not differ significantly. The results are interpreted as support for a common biological determinant of cognitive ability and male sexual orientation.     

Color preferences according to gender and sexual orientation

The present study was undertaken to verify findings surrounding sex differences in color preferences, and to extend this realm of inquiry by looking for possible differences in color preferences associated with sexual orientation. Based on a large sample of North American college students, significant gender differences were found, with the main difference being a greater preference for shades of blue by males than by females. Females, on the other hand, tended to be more evenly divided than males between preferring both green and blue. Regarding sexual orientation, we found no significant differences between heterosexuals and homosexual/bisexuals of either gender. In other words, male and female homosexuals/bisexuals exhibited essentially the same configuration of color preferences as did their heterosexual counterparts.     

Sexual orientation and spatial memory

The present study aimed at determining the influence of sexual orientation in human spatial learning and memory. Participants performed the Boxes Room, a virtual reality version of the Holeboard. In Experiment I, a reference memory task, the position of the hidden rewards remained constant during the whole experiment. In Experiment II, a working memory task, the position of rewards changed between blocks. Each block consisted of two trials: One trial for acquisition and another for retrieval. The results of Experiment I showed that heterosexual men performed better than homosexual men and heterosexual women. They found the rewarded boxes faster. Moreover, homosexual participants committed more errors than heterosexuals. Experiment II showed that working memory abilities are the same in groups of different sexual orientation. These results suggest that sexual orientation is related to spatial navigation abilities, but mostly in men, and limited to reference memory, which depends more on the function of the hippocampal system.     

Differences in selective processing of nonemotional information between agoraphobic and normal subjects

Abstract

The performance of agoraphobic and normal subjects is compared across three different types of task (Kamin blocking effect, incidental learning, and choice reaction time) all designed to tap processing of neutral stimuli. Agoraphobics differed from normals on the Kamin blocking task and on one of the two incidental learning measures employed. Choice reaction time performance was the same in both groups. The relevance of these findings for future studies of emotional processing in such subjects is discussed.     

Friendship trumps ethnicity (but not sexual orientation): comfort and discomfort in inter-group interactions

An experience sampling study tested the degree to which interactions with out-group members evoked negative affect and behavioural inhibition after controlling for level of friendship between partners. When friendship level was statistically controlled, neither White nor Black participants reported feeling more discomfort interacting with ethnic out-group members compared to ethnic in-group members. When partners differed in sexual orientation, friendship level had a less palliating effect. Controlling for friendship, both gay and straight men - but not women - felt more behaviourally inhibited when interacting with someone who differed in sexual orientation, and heterosexual participants of both genders continued to report more negative affect with gay and lesbian interaction partners. However, gay and lesbian participants reported similar levels of negative affect interacting with in-group (homosexual) and out-group (heterosexual) members after friendship level was controlled. Results suggest that much of the discomfort observed in inter-ethnic interactions may be attributable to lower levels of friendship with out-group partners. The discomfort generated by differences in sexual orientation, however, remains a more stubborn barrier to comfortable inter-group interactions.     

An experimental analysis of exposure to “explicit” heterosexual stimuli as an effective variable in changing arousal patterns of homosexuals

The effect of exposure to explicit heterosexual stimuli on heterosexual arousal was experimentally analyzed in four homosexuals in a series of single case experimental designs. Each subject was sequentially exposed to films of female or male sexual content under positive therapeutic instructions. Penile response to female slides in separate measurement sessions increased during exposure to the female film, decreased during exposure to the male film, and increased once again when the female film was reinstated. The increase in penile response to female stimuli was paralleled in many instances by changes in masturbatory fantasy, reports of arousal and heterosexual behavior outside the laboratory. Increasing heterosexual arousal had little effect on homosexual responsivity. Results are discussed in terms of exposure facilitating extinction of avoidance responses toward females and providing new sexual fantasy content.     

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.     

Evidence from a homosexual sample for a sex‐specific rival‐oriented mechanism: Jealousy as a function of a rival's physical attractiveness and dominance

Among heterosexual women in particular, a rival's physical attractiveness evokes jealousy, whereas among heterosexual men in particular, a rival's dominance evokes feelings of jealousy. The present study conducted with gay men and lesbian women examined whether these sex‐differentiated responses reflect an evolved sex‐specific rival‐oriented mechanism according to which males and females pay attention to different rival characteristics or an evolved general partner‐oriented mechanism, according to which males and females pay attention to those characteristics that their actual and potential partners find important. In an experiment, using a 2 (Participant Sex) × 2 (Rival Physical Attractiveness) × 2 (Rival Dominance) mixed factor design, homosexual participants were presented with a scenario in which their partners were flirting with an individual of the same sex. Lesbian women, but not gay men, reported more jealousy when they were exposed to a physically attractive rival as compared with a physically unattractive rival. Gay males, but not lesbian women, reported more jealousy when they were exposed to a rival high in dominance as compared with a rival low in dominance, especially when exposed to a physically unattractive rival. In addition, among women high in dominance, a dominant rival evoked relatively less jealousy, and among women high in social comparison orientation, an unattractive rival evoked relatively more jealousy. It is concluded that males and females posses an evolved sex‐specific rival‐oriented mechanism through which they respond more or less automatically to those rival characteristics that have been important in sexual selection in our evolutionary past.     

Patterns of Sexual Coercion in Adult Heterosexual Relationships: An Exploration of Male Victimization

The sexual coercion of adult males by females in heterosexual relationships has received little empirical attention. The purpose of this study was to identify and describe such relationships — in comparison with relationships involving the sexual coercion of females, of both males and females, and of neither — through analysis of data for 3,032 couples that completed the Preparation for Marriage instrument ( Holman, Busby, & Larson, 1989 ). Current individual and couple characteristics were investigated for male subjects and their partners. The results revealed greater deficiencies in relational resources and commitment in coercive versus noncoercive couples. In addition, gender differences were noted among results for different victim/offender configurations.     

Actual differences and stereotypical perceptions in body image and eating disturbance: A comparison of male and female heterosexual and homosexual samples

In the present study, 32 homosexual males (HMM), 32 homosexual females (HMF), 32 heterosexual males (HTM), and 32 heterosexual females (HTF) completed measures of body image disturbance and concerns with weight and dieting from five different perspectives: self, and typical homosexual male, heterosexual male, heterosexual female, and homosexual female. Participants were primarily Caucasian. Results indicated that, in general, HMMs and HTFs showed greater actual concerns with appearance, weight, and dieting, and were perceived to possess greater body image disturbance and dieting concerns compared to HTMs and HMFs. Subjects also held various stereotypic misperceptions about certain target groups such that HTFs and HMMs were predicted to possess greater body image disturbance and be more concerned with weight and dieting than was actually true. In addition, subjects made accurate predictions about HTMs overall, but were inconsistent in their predictions of HMFs on these measures. Results are discussed in terms of possible variation in the degree of importance these attributes may have for members of these four populations and how such differences may lead to an increased risk for developing eating disorders among heterosexual females and homosexual males.     

Gay Stereotypes: The Use of Sexual Orientation as a Cue for Gender-Related Attributes

This study investigated whether gay men and lesbians are assumed to have attributes stereotypically associated with the other gender. Participants were 110 male and female undergraduates from a private, Midwestern, U.S. university. Participants were randomly assigned to one of four conditions (i.e., gay male, lesbian, heterosexual female, heterosexual male) and rated their given target on possession of traditionally masculine and feminine occupational interests, activities, and traits. Results revealed that, despite some changes in the status of gay men and lesbians in society, stereotypes regarding sexual orientation were similar to those seen in studies conducted 20 years ago. Specifically, gay males were viewed as less masculine/more feminine than heterosexual males, and lesbians were viewed as more masculine/less feminine than heterosexual females.     

He's gotta have it: shopping dependence and the homosexual male clothing consumer

Shopping is not always ‘fun’ and is not always ‘therapeutic’, yet, the negative aspects and motivations for this behaviour have received little attention. Consumers often may be dependent upon shopping activity to satisfy personal needs, such as emotional repair and self‐image, which are far removed from the acquisition and use of products. Not only may this dependence be dysfunctional in that it signals an individual's inability to control their shopping behaviour but also it may be symptomatic of more serious problems, such as compulsive and even addictive shopping. This paper explores this shopping dependence in the context of fashion clothing consumption. Male consumers are considered, with sexual orientation employed as an indicator of behaviour. Data from a survey of 225 homosexual and 225 heterosexual UK males suggest that homosexual males display clothes shopping dependence, and at a level that is significantly stronger than for heterosexuals. Younger males show a greater tendency to display such behaviour, with dependence declining with age for both groups. Managerial and research implications are considered.
