Abstract
Alcohol is often consumed in group settings. The present article examines the effect of alcohol on intergroup competitiveness through the use of a prisoner's dilemma game. One hundred fifty-eight college students participated in the study, either individually or as a member of a 4-person experimental single-sex group. Participants consumed either alcohol (1.13 g ethanol/kg body weight) or a placebo. Results show no effect of alcohol on cooperative choice within individuals. However, groups were significantly less cooperative after consuming alcohol than they were after consuming a placebo. In addition, after consuming alcohol, groups were less cooperative than were individuals. Results are discussed in terms of the way alcohol may affect focus of attention on group-level cues.
