As a test of the nonlaboralory generalizability of attraction research, a computer dating field study was conducted. A SO-item questionnaire of attitudes and personality was administered to a 420-student pool, and 44 male-female pairs were selected on the basis of maximal or minimal similarity of responses. Each couple was introduced, given differential information about the basis for their matching, and asked to spend 30 minutes together at the Student Union on a "coke date." Afterward, they returned to the experimenter and were independently assessed on a scries of measures. It was found that attraction was significantly related to similarity and to physical attractiveness. Physical attractiveness was also significantly related to ratings of desirability as a date, as a spouse, and to sexual attractiveness. Both similarity and attractiveness were related to the physical proximity of the two individuals while they were talking to the experimenter after the date. In a follow-up investigation at the end of the semester, similarity and physical attractiveness were found to predict accurate memory of the date's name, incidence of talking to one another in the interim since the coke date, and desire to date the other person in the future.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
