After studying the behavior of 120 school kids in Melbourne, Australian researcher Grant Devilly concluded that is no prove that links violence and video games.

"If you have a quite hyper kid, they will come down after playing a bit, but for the rest of the kids, the vast majority, it makes no difference at all in their general aggression rate," Devilly said.

His finding was that those predisposed to violence, and who were more reactive to their environments, changed their behaviour after playing a violent video game. Some became aggressive and some did not."The majority of people didn't increase in aggression at all - and we are not the first people to find that," Devilly said.

The Swinbourne University study relied on monitoring the behaviour of children after a 20-minute session with the violent video game Quake II.

The team conducted three studies, published in the American Psychological Association's Journal of Experimental Psychology, that found players of the games tend to be more aggressive drivers and are more prone to accidents, The Telegraph newspaper of London reported Monday.

Two of the studies found that interviewees admitted to having more aggressive feelings toward driving and to taking more risks after playing the games, while the third, which employed the use of a driving simulator, found that men took more risks on the simulator after playing the games. The amount of risk-taking was not increased for women.

"Risky media content, as provided by racing games, activates feelings of arousal and excitement related to increased risk taking ... at least in men," said team member Peter Fischer."We conclude that playing computer games could provoke unsafe driving.

"Road traffic practitioners should bear in mind the possibility that racing games indeed make road traffic less safe, not least because game players are mostly young adults, acknowledged as the highest accident-race group."
