Human physical aggression as a function of alcohol and threat of harm

Abstract

The present study investigated the effect of threat of physical harm on the aggressive behavior of intoxicated and nonintoxicated subjects. Forty male undergraduates competed in a reaction time task in which they could deliver shock to an increasingly provocative opponent. In the threat condition, subjects could be hurt by the opponent (they wore a shock electrode), while in the no-threat condition, they could not be hurt by the opponent (the electrode was removed prior to the competition). The results indicated that under conditions of low provocation, the intoxicated subjects behaved more aggressively than the nonintoxicated subjects in both the threatening and nonthreatening condition. However, under conditions of increasing provocation, only the intoxicated subjects in the threatening condition increased their shock settings.
