Abstract:
In this research the authors examined the accuracy of judging sexual orientation on the basis of brief observations or "thin slices" of nonverbal behavior. In Study 1, sexual orientation was judged more accurately than chance, with judgments being more accurate when based on dynamic nonverbal behavior (10-s and 1-s silent video segments) than on static information (a series of 8 still photographs). Gay men and lesbians were more accurate than heterosexuals in judging still photographs and 1-s clips but not in 10-s clips. In Study 2, judgments based on 10-s dynamic figural outline displays containing primarily gestural information were more accurate than chance.
