dc.description.abstractThis research was the first experimental study to investigate the effect of video gaming on measures of cooperative behavior from an evolutionary standpoint. The final sample comprised a total 117 participants (39 male, 78 females), with a mean age of 24 years (SD = 8.93). Participants were randomly assigned to 1 of 4 media conditions (violent book, violent video game, nonviolent video game, and violent TV show) and measured on prosocial behavior before any media exposure and assessed on cooperative behavior after media exposure. Novice and regular gamers did not differ on prosocial behavior before gaming. After media exposure, a self-constructed version of the iterated Prisoner’s Dilemma game was used to measure cooperation. Further analyses were then conducted to measure differences between conditions on cooperative behavior. It was found that regular and multiplayer gamers were not significantly higher or lower on measures of cooperative behavior compared to novices or solitary gamers. Although nonsignificant, effect sizes were consistent with past research which suggests heightened cooperation in regular gamers. Media type exposure did not have a significant effect on cooperative behavior. Findings suggest that cooperative behavior is not less prominent in regular or multiplayer gamers than novices or solitary gamers. These results indicate that, contrary to the predictions one may make from the GAM model of violent gaming (Anderson & Bushman, 2001), violent media exposure does not appear to produce reductions in prosocial or cooperative behavior.
