As computer games get to look more lifelike, it seems that their violence is spilling over into real life. It is reported that some dozens of children have been murdered since 1997, which has been linked to all obsession (着迷) with violent video games. Recently the parents of a 14-­year-­old murder victim in the UK blamed the killer's obsession with the game Manhunt, causing a government review of legislation (立法) to protect children.

Psychologists think there may be many reasons why violent games are more harmful to children than violent movies. Firstly, players are actively involved in violence, and may begin to see using weapons as second nature. Secondly, violent games provide repetitive aggressive (侵犯的) experiences that are rewarded by more killing.

Many studies have shown that people who play violent games regularly are more likely to show high levels of aggression. For instance, in 2000, scientists in Iowa State University found that people who played violent games were more likely to admit involvement in aggressive behaviors, including assaults (侵犯人体罪) or robberies.

A study of 13 to 14-­year­-old children showed that more than half had played games recommended only for over­18s. The more violent the games they played, the more they considered physical aggression to be acceptable. Besides, children who play violent games are more prone (有做……倾向的) to arguing with teachers and fighting.

Experimental studies have also hinted at a possible link. In one, scientists asked a group of students to play a violent game, while another group played the non­violent. Those who played the violent games were faster to react to aggressive words subsequently (随后) flashed on screen.
