This study investigated the effects of violent video game play and trait hostility on attentional bias toward negatively valenced words. Following video game play, participants completed an emotional Stroop task. Results indicated greater Stroop interference for participants high in trait hostility and for participants playing violent video games. Implications of these findings are discussed with respect to current models of aggressive behavior. (PsycINFO Database Record (c) 2008 APA, all rights reserved)(from the journal abstract)
