Summary The effects of viewing an aggressive model on the observer's subsequent aggression were studied in three field experiments. Although Ss who saw a model criticize someone for blocking his car were not significantly more aggressive than those observing a neutral model, Ss who saw a model berate someone for bumping into him or butting in line later behaved more aggressively than those who had observed a polite model. Male Ss were significantly more aggressive than female Ss in the automobile experiment, but not in the other two.
