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.  相似文献

Much has been written about the low self-esteem of adolescent girls relative to adolescent boys, but little research has explored the role that friendship quality may play in affecting self-esteem. Ninety-seven female and 67 male 11th and 12th graders completed measures of self-esteem and of friendship quality with both same- and cross-gender best friends. Ninety-five percent of the participants were White, and ranged across the socioeconomic spectrum with the majority coming from middle-class families. We found that girls' self-esteem was significantly lower than boys' self-esteem and that girls rated their relationships as stronger, more interpersonally rewarding, and more stressful than boys did. Boys reported that their friendship with their best female friend was more interpersonally rewarding than their friendship with their best male friend, whereas girls rated the quality of their same- and cross-gender friends similarly. As expected, girls' self-esteem was positively correlated with the friendship quality of their cross-gender best friend. However, their self-esteem was not correlated with the quality of their same-gender friendship. Boys' self-esteem did not correlate with the quality of their same- or cross-gender best friendship. Results may help us understand the relatively low self-esteem experienced by adolescent girls.  相似文献

The present study fills a crucial gap in literature surrounding the lives of African American men by exploring factors that shape the quality of these men's friendships. Drawing on data from a sample of 171 African American men, the study examines the relative utility of subjective religiosity, subjective spirituality, advice exchange, and affective sharing as predictors of the level of perceived support from male and female friends. Findings reveal age differences in subjective religiosity, subjective spirituality, and in level of advice and affective exchange in men's same-sex as well as cross-sex friendships. Age differences emerged in men's perceptions of the supportiveness of their friendships with women but not with men. Age was not a predictor of perceived supportiveness of same-sex or cross-sex friendships. Subjective religiosity did not predict support in same-sex or cross-sex friendships. Subjective spirituality positively predicted perceived support in men's same-sex friendships but not in cross-sex friendships. Implications of these findings are discussed.  相似文献

To search for genetic influence on human fertility differentials appears inconsistent with past empirical research and prior interpretations of Fisher's fundamental theorem of natural selection. We discuss Fisher's theorem and give reasons why genetic influences may indeed account for individual differences in human fertility. We review recent empirical studies showing genetic influence on variance in fertility outcomes and precursors to fertility. Further, some of the genetic variance underlying fertility outcomes overlaps with that underlying fertility precursors. Findings from different cultures, different times, different levels of data, and both behavioral and molecular genetic designs lead to the same conclusion: Fertility differentials are genetically influenced, and at least part of the influence derives from behavioral precursors that are under volitional control, which are themselves genetically mediated.  相似文献

This article provides a construct-by-construct review of the effectiveness of sexual asault prevention programs in modifying sexual assault-related attitudes, cognitions, emotions, and behaviors. This article also discusses variables that may moderate program effectiveness, variables that may mediate program effectiveness, methodological issues, programs for special populations, and iatrogenic effects. In general, sexual assault prevention programs have been shown to be effective in producing short-term reductions in rape-supportive attitudes. There is insufficient evidence, however, to conclude that such programs are effective in reducing the incidence of sexual assault.  相似文献

Three preschool children participated in a behavioral training program to improve their gross-motor skills. Ten target behaviors were measured in the training setting to assess direct effects of the program. Generalization probes for two gross-motor behaviors, one fine-motor skill, and two social behaviors were conducted in other settings. Results indicated that the training program improved the gross-motor skills trained and that improvements sometimes generalized to other settings. Contrary to suggestions in educational literature, the gross-motor training program did not produce changes in fine-motor skills or social behaviors. Implications for educators and for the development of the technology of generalization are outlined.  相似文献

We review four articles from JEAB's March 1994 issue celebrating the contributions of Joseph V. Brady. These articles have implications for studying private events and for studying multiple operants. We suggest that regularly including self-reports about private events in behavioral pharmacological research has resulted in an accumulated knowledge that has facilitated examination of interesting relations among self-reports, environmental factors, and other observable behaviors. Methodological lessons that behavioral pharmacologists have learned regarding the study of multiple operants are also relayed. We provide examples of how these lessons could be useful to applied behavior analysts studying nonpharmacological issues.  相似文献
