Effects of Ethnic Group Cultural Differences on Cooperative and Competitive Behavior on a Group Task

This study examined the hypothesis that differences in the cultural norms of Anglo-Americans and three other ethnic groups—Asian, Hispanic, and Black Americans—will result in different behaviors on a group task. Student subjects were assigned to ethnically diverse or allAnglo groups. Individual and group responses were measured using a Prisoner's Dilemma task in which participants could choose to compete or cooperate with another party. We hypothesized that groups composed of people from collectivist cultural traditions would display more cooperative hehavior than groups composed of people from individualistic cultural traditions. Results confirmed this hypothesis. Implications for future research and for organizations seeking to manage diversity are discussed.
