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.
本研究调查了媒体暴力引发的认知和情绪是否会介导攻击行为。80名本科生，40名男性和40名女性参与了该实验。首先，让受试者观看四段暴力视频中的一段，这些视频在暴力程度和娱乐性方面有所不同。在受试者观看视频时，持续记录他们的心率和眨眼率。观看视频后，受试者描述他们在观看时产生的想法，并对他们对视频的情感反应进行评分。最后，测量他们的攻击行为。结果表明：（1）暴力程度高的视频引发了更多的攻击想法、更多的负面情绪想法、更强烈的负面情绪以及更强烈的空虚无力感，而娱乐性高的视频引发了更强烈的积极情绪；（2）在生理反应和攻击行为方面，各视频之间未发现显著差异；（3）媒体暴力引发的认知和情绪并未介导攻击行为。
