Most research on violent video game play suggests a positive relationship with aggression-related outcomes. Expanding this research, the current study examines the impact group size, game motivation, in-game behavior, and verbal aggression have on post-game play hostility. Consistent with previous research, group size and verbal aggression both displayed a significant positive relationship with hostility. From these results, avenues for future research on anti- and prosocial outcomes from group gaming are offered. (PsycINFO Database Record (c) 2008 APA, all rights reserved)(from the journal abstract)
