This study investigated whether cognitions and emotions elicited by media violence mediate aggressive behavior. Eighty undergraduates, 40 men and 40 women, participated in the experiment. First, subjects were exposed to one of four violent videos which varied in levels of violence and entertainment. Subjects' heart rate and eyeblink rate were continuously recorded while they watched the video. After watching it, subjects described their thoughts which occurred while watching it and rated their affective reactions to it. Finally, their aggressive behavior was measured. Results showed that (1) videos high in violence elicited more aggressive thoughts, more thoughts of negative affect, stronger negative affects, and stronger empty-powerless affects, whereas videos high in entertainment elicited stronger positive affects; (2) no significant differences were found among the videos in terms of physiological reactions and aggressive behavior; and (3) cognitions and emotions elicited by media violence did not mediate aggressive behavior.
