Category Specificity of Self-Reported Sexual Attraction and Viewing Times to Male and Female Models in a Large U.S. Sample: Sex, Sexual Orientation, and Demographic Effects.

Recent research has documented large and robust sex differences in the category specificity of self-reported sexual attraction and viewing times to men and women, with men showing more polarized responses to the two sexes than women. However, this research has been limited by the use of small and restricted samples. To address this, the current study assessed a representative sample of more than 2800 U.S. adults on demographic and attitudinal variables and on two measures of category specificity: one based on self-reported sexual attraction and the other based on viewing times to male and female swimsuit models. Key findings were replicated. On average, men were considerably more category specific in self-reported sexual attraction and viewing times than women, and this was true for both heterosexual and homosexual participants. Self-identified bisexual and asexual participants tended to be lower on category specificity than other groups. Although demographic and attitudinal factors such as age, ethnicity, state and region of residence, social class, political liberalism-conservatism, and religiousness were sometimes weakly related to category specificity, sex differences in category specificity remained robust despite demographic and attitudinal variation.
