Violent(暴力的) computer games have been strongly connected with aggression(好斗) in teenager boys in a study that shows the machines are increasingly becoming substitutes(替代品)for friendship.

The research provides powerful support to the doubt that actual violence could be one of the factors behind the crimes of aggression including young people. John Colwell, a lecturer at Middlesex University, who carried out the research, said aggression in boys seemed to increase with the amount of playing such games. “There are many facts to suggest there is a connection between playing computer games and aggression,” he said.

Previous studies have shown only a certain relation between such games and aggression. This conclusion was uncertain because it could mean that children who played the games did so because they had shown a sign to violence. Colwell's work shows, however, that there is a strong link, meaning that playing such games makes children more aggressive. He reached his conclusions after studying the behavior of 204 pupils aged 12-14 from a school in north London.

Children became obviously more aggressive the longer they had been playing violent games. They shouted, pushed and hit other children. Those who played in occasional bursts showed little effect. All the children spent many hours playing such games. Nearly 97% of boys and 88% of girls were regular users. Almost the boys, the heaviest computer users tended to have the fewest friends and reported seeing their machine as a friend.
