actually research on brain activity using CAT scans and MMRI, have found that the activity in the brain while playing or watching violent scenes, is exactly the same as when watching a real violent scene..
ie, the same part that gets activated in reality is activated when playing a video game. this finding indicates that people get immersed in the game /movie that their brains do not distinguish fantasy violence from reality..

more over, from a behavioural perspective, it makes sense that playing violent games, will make the violent act more salient, and so it would be the first response ( it comes out easily)!!
