Prior research has indicated an association between exposure to violent media and aggressivethoughts, feelings, and behavior, potentially as a result of effects on inhibitory mechanisms. However, the role of violence in video games in modulating subsequent neural activity related to cognitive inhibition has received little attention. To examine short-term effects of playing a violent video game, 45 adolescents were randomly assigned to play either a violent or a nonviolent video gamefor 30 minutes immediately prior to functional magnetic resonance imaging ( fMRI). During the fMRI procedure, participants performed a go/no-go task that required them to press a button for each target stimulus and
