Exposure to violent media has been widely linked to increased aggression. In the present research, we examined whether violent media exposure would be associated with increased aggression, which would then spread within social networks like a contagious disease. Two groups of first year psychology students completed a questionnaire three times over the course of a year, measuring their media exposure, aggression, personality, and social relations within the group. Cross-sectional analysis provided mixed results in regards to the link between violent media and aggression. Siena analysis found no evidence of homophily (i.e., participants were not more likely to be friends with others similar to themselves) nor of social influence (i.e., participant's behavior did not predict a change in their friends' behavior). However, given the relatively small sample sizes and the weak ties between participants, more work is needed to assess the spread of violent media effects.
接触暴力媒体与攻击性的增加广泛相关。在本研究中，我们检验了暴力媒体的接触是否会与攻击性的增加相关，而这种增加是否会像传染病一样在社交网络中传播。两组一年级心理学学生在一年的时间里完成了三次问卷调查，测量他们的媒体接触、攻击性、个性以及群体内的社会关系。横断面分析提供了关于暴力媒体和攻击性之间联系的混合结果。辛纳分析发现，没有证据表明同质性（即参与者与自己相似的人更有可能成为朋友）或社会影响（即参与者的行为并不能预测其朋友行为的改变）。然而，鉴于参与者之间的样本量较小且联系较弱，需要进一步的研究来评估暴力媒体影响的传播。
