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.
Aggressionism
The concept of aggressionism is based on the root word "aggression." In this particular concept, aggression occurs in all species as a form of protection of their own or of their territory in order to keep their young safe. However, though most species protect against their predators, some also protect from their own. For example, lions are very territorial and fight other grown, male lions to keep their status as the alpha. Similar to humans, if an invader attacks, human instinct leads them to defend oneself and fend them off. When necessary, for the sake of survival, most species become aggressive to get food to survive. Yet, aggressionism isn't the same as aggression. Aggressionism is the concept of aggression particularly made for humans, as it is more complex than simply wanting to survive. This is demonstrated in one of its definitions describing it as "the action of a state in violating by force the rights of another state, particularly its territorial rights; an unprovoked offensive, attack, invasion, or the like..." or a "hostile or destructive mental attitude or behavior" which leads to conflict and eventually, bloodshed.
