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.
Aggression
According to philosopher and neuroscientist Nayef Al-Rodhan, "fear(survival)-induced pre-emptive aggression" is a human reaction to injustices that are perceived to threaten survival. It is often the root of the unthinkable brutality and injustice perpetuated by human beings. It may occur at any time, even in situations that appear to be calm and under control. Where there is injustice that is perceived as posing a threat to survival, "fear(survival)-induced pre-emptive aggression" will result in individuals taking whatever action necessary to be free from that threat.
