Previous studies investigating the familial nature of sexual orientation have often relied on the reports of siblings. They have generally obtained extremely high accuracy rates for proband rating of the sexual orientation of siblings. However, participants in these studies have probably been unusually open about their sexual orientation, and thus it is uncertain if more representative particip...

The impact of types of social connectedness-family, other adult, and school-on suicide ideation and attempts among all youth, the relative impact of each type, and effect modification by sexual orientation was assessed. Data were from the 2007-2009 Milwaukee Youth Risk Behavior Surveys. Multivariable logistic regression analyses calculated the risk of suicide ideation and attempts by sexual ori...

The present study examined sexual orientation-related differences in object location memory by using 3 object arrays (testing object exchange, object shift, and novel objects conditions) and 1 metric positional memory array. Heterosexual women and homosexual men significantly outperformed heterosexual men in all 3 object arrays. However, there were no group differences in metric positional memo...

The United States has recently made significant and positive civil rights gains for LGB people, including expanded recognition of marriages between people of the same sex. Among the central tropes that have emerged in the struggle for the rights of LGB people are that they are "born that way," that sexual orientations cannot change, and that one's sexual orientation is not affected by choice. W...

The notion that an individual’s sexual orientation can be ascertained through distinctive speech patterns abounds in popular culture. This article reviews the small but growing body of literature examining whether sexual orientation is conveyed and perceived through speech. These studies show some individuals speak in a way that conveys their sexual orientation to naïve listeners. Contrary to m...

The current study explored the relation between sexual orientation, media persuasion, and eating and body image concerns among 78 college men (39 gay; 39 straight). Participants completed measures of sexual orientation, eating disorder symptoms, appearance-related anxiety, perceived importance of physical attractiveness, perceptions of media influence, and media exposure. Gay men scored signifi...

Sexual differentiation of the human brain has been suggested to take place through exposure to sex steroids during intrauterine development. Animal experiments have shown that interference in this process by underfeeding of the mother can result in feminization of the male offspring. We explored the possible effects of prenatal exposure to famine on sexual orientation and gender identity in hum...

\s=b\ Recent studies postulate biologic factors as the primary basis for sexual orientation. However, there is no evidence at present to substantiate a biologic theory, just as there is no compelling evidence to support any singular psychoso-cial explanation. While all behavior must have an ultimate biologic substrate, the appeal of current biologic explanations for sexual orientation may deriv...
