This study examined whether electronic games foster aggression. Results indicated that players’ perceived competence was positively related to gaming motivation, which was in turn, negatively associated with player aggression. So players who perceived themselves as competent were less likely to display aggression. However, competence-impeding play led to higher levels of aggressive feelings, easier access to aggressive thoughts, and a greater likelihood of enacting aggressive behaviour. Overall, this pattern of effects was not influenced by whether or not the game contained violent content.
