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.
Learned helplessness
Learned helplessness is behavior that occurs when the subject endures repeatedly painful or otherwise aversive stimuli which it is unable to escape from or avoid. After such experiences, the organism often fails to learn or accept "escape" or "avoidance" in new situations where such behavior is likely to be effective. In other words, the organism learned that it is helpless. In situations where there is a presence of aversive stimuli, it has accepted that it has lost control and thus gives up trying, even as changing circumstances offer a method of relief from said stimuli. Such an organism is said to have acquired learned helplessness. Learned helplessness theory is the view that clinical depression and related mental illnesses may result from such real or perceived absence of control over the outcome of a situation.
