Abstract:  Conducted a study with 64 male undergraduates to examine the conditions under which media violence would “facilitate” aggression in angered individuals. It was noted that previous research has lacked support for facilitation due to improper control groups. It was predicted, based upon evidence that aggressive and neutral films are capable of both arousing a S and shifting his/her attention away from previous anger instigation (attentional shift), that only under a condition where an aggressive film is viewed prior to anger arousal will increased aggression occur if compared to a no-film control. Results indicate that when Ss were angered prior to film exposure, neutral films reduced aggression, with aggressive films not differing from a no-film control. Under subsequent anger arousal, however, there was a facilitation for aggressive film exposure. Implications of this study along with those from other recent media violence studies are discussed.
