ABSTRACT
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.
