This study experimentally tested whether individuals have a tendency to associate attractive voices with attractive faces and, alternately, unattractive voices with unattractive faces. Participants viewed pairings of facial photographs of attractive and unattractive individuals and had listened to attractive and unattractive voice samples and were asked to indicate which facial picture they thought was more likely to be the speaker of the voice heard. Results showed that there was an overall tendency to associate attractive voices with attractive faces and unattractive voices with unattractive faces, suggesting that a “what-sounds-beautiful-looks-beautiful” stereotype exists. Interestingly, there was an even stronger propensity to pair unattractive voices to unattractive faces than for the attractive voice–face matching.

An abundance of unwanted sexual opportunities perpetrated by insensitive, physically and sexually abusive men may be a factor in the expression of homosexuality in some women. In the present study, we examined self-reports of dating histories, sexual experiences, and physical and sexual abuse among lesbians and heterosexual women. Lesbians with prior heterosexual experience reported more severe and more frequent physical abuse by men. Lesbians also reported more instances of forced, unwanted sexual contact perpetrated by men, and this sexual abuse occurred at a significantly earlier age. These data show that adverse experiences with the opposite sex are more common in lesbians than heterosexual women, and therefore negative heterosexual experiences may be a factor in the expression of a same-sex sexual orientation in women. We propose an evolutionary psychological interpretation of this phenomenon based on the cardinally different mating strategies of women and men that have evolved for maximizing the likelihood of reproduction.

This study provides a descriptive account of kissing behavior in a large sample of undergraduate college students and considers kissing in the context of both short-term and long-term mating relationships. Kissing was examined as a mate assessment device, a means of promoting pair bonds, and a means of inducing sexual arousal and receptivity. A total 1,041 college students completed one of three questionnaires measuring kissing preferences, attitudes, styles, and behaviors. Results showed that females place more importance on kissing as a mate assessment device and as a means of initiating, maintaining, and monitoring the current status of their relationship with a long-term partner. In contrast, males place less importance on kissing, especially with short-term partners, and appear to use kissing to increase the likelihood of having sex. The results suggest that kissing may play an important role as an adaptive courtship/mating ritual.
