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.
Psychological abuse
When considering the emotional state of psychological abusers, psychologists have focused on aggression as a contributing factor. While it is typical for people to consider males to be the more aggressive of the two sexes, researchers have studied female aggression to help understand psychological abuse patterns in situations involving female abusers. According to Walsh and Shluman, "The higher rates of female initiated aggression [including psychological aggression] may result, in part, from adolescents' attitudes about the unacceptability of male aggression and the relatively less negative attitudes toward female aggression". This concept that females are raised with fewer restrictions on aggressive behaviors (possibly due to the anxiety over aggression being focused on males) is a possible explanation for women who utilize aggression when being mentally abusive.
