A study of 120 children aged 11 to 15 by the Swinburne University of Technology revealed most kids are unaffected by violent games. However, children who have a tendency towards aggression will become a bit more aggressive by playing violent video games.
But for the majority of children there was no difference in behaviour, according to the research published in the Psychology, Crime and Law journal.
The study monitored the behaviour of children from 10 schools in eastern and southern metropolitan Melbourne before and after playing the violent video game Quake II for 20 minutes, Swinburne's Professor Grant Devilly said.
Prof Devilly said only children predisposed to aggression and more reactive to their environments changed their behaviour after playing and of those only some showed more aggression.
"They were a little bit more aggressive anyway in their interaction with life," he said.
"The majority of people did not increase in aggression at all and we're not the first people to find that."
