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.

摘要

人们经常在群体环境中饮酒。本文通过囚徒困境博弈来研究酒精对群体间竞争的影响。158名大学生参与了这项研究，他们要么单独参与，要么作为4人实验性单性别小组的成员参与。参与者要么饮用酒精饮料（每千克体重1.13克乙醇），要么饮用安慰剂。结果表明，酒精对个体内部的合作选择没有影响。然而，与饮用安慰剂后相比，饮酒后小组的合作显著减少。此外，饮酒后，小组比个体更不合作。本文从酒精可能影响对群体层面线索的注意力焦点的角度对结果进行了讨论。
