Effects of violent video games on players’ and observers’ aggressive cognitions and aggressive behaviors

Abstract

Although previous research has shown that exposure to violent video games is related to aggression, little is known about the relationship between the player’s perspective (player vs. observer) and aggression. In this experimental study, we tested the short-term effects of actively playing versus passively observing the same type of video games on aggressive cognitions and aggressive behaviors. A total of 192 12-year-old children (50% girls) were randomly assigned to one of four conditions: (a) violent game player (active violent players), (b) violent game observer (passive violent observers), (c) neutral game player (active neutral players), or (d) neutral game observer (passive neutral observers). After either playing or observing the designated games, each participant completed a lexical decision task and a competitive reaction time task to measure their aggressive cognitions and behaviors. Results showed that players displayed more aggressive cognitions and behaviors than observers. Boys displayed more aggressive cognitions and behaviors than girls, but this trend was observed only in the violent game play condition. Mediational analysis suggested that aggressive cognitions partially mediated the effect of violent video games on aggressive behaviors.
