Aggression
Some scholars believe that behaviors like aggression may be partially learned by watching and imitating people's behavior, while other researchers have concluded that the media may have some small effects on aggression. There is also research questioning this view. For instance, a long-term outcome study of youth found no long-term relationship between playing violent video games and youth violence or bullying. One study suggested there is a smaller effect of violent video games on aggression than has been found with television violence on aggression. This effect is positively associated with type of game violence and negatively associated to time spent playing the games. The author concluded that insufficient evidence exists to link video game violence with aggression. However, another study suggested links to aggressive behavior.
Hostile attribution bias
In addition, hostile attribution bias is hypothesized to be one important pathway through which other risk factors, such as peer rejection or harsh parenting behavior, lead to aggression. For example, children exposed to peer teasing at school or child abuse at home are much more likely to develop high levels of hostile attribution bias, which then lead them to behave aggressively at school and/or at home. Thus, in addition to partially explaining one way aggression develops, hostile attribution bias also represents a target for the intervention and prevention of aggressive behaviors.
