Violent video games don't produce anti-social behaviour in player, study finds Call Of Duty Black Ops. ANTI-SOCIAL and violent video games do not produce anti-social behaviour in players, according to an Australian study released today, debunking previous research in the field. The new study has been welcomed by industry experts, who say research has yet to prove video games cause any negative short-term affects for players. The game research, conducted at the University of Queensland, tested three groups of university students using four types of video games - violent, anti-social, pro-social and non-violent - and their behaviour during or after their gaming session. Video game State of Decay banned in Australia Mad max to have hint of Aussie accent While participants thought responses to questionnaires were part of the study, researchers actually tested them by dropping a group of pens on the floor during or after gameplay and waiting to see if participants would help to retrieve them. The study found playing anti-social (Grand Theft Auto) and violent games (Call of Duty: Black Ops) compared to pro-social (World of Zoo) and non-violent games (Portal 2) had little effect on the helpfulness of players. Only when the researchers dropped the pens in the middle of the session did it have a substantial effect on helpfulness, actually increasing helpers from 37.5 per cent of those playing anti-social games to 87.5 per cent. "We failed to find evidence that playing video games affect pro-social behaviour," the study concluded. Here we fail to substantiate conjecture that playing contemporary, violent video games will lead to diminished pro-social behaviour. Interactive Games and Entertainment Association chief executive Ron Curry said the study backed up other research in the field and proved modern video games caused no short-term negative affects. "We've seen, over the last 10 years, this explosion in the uptake of video games and a lot of those are violent video games, yet in the same period we haven't seen a corresponding increase in violent behaviour," Mr Curry said. That doesn't mean all video games are suitable for all people. Some media is not suitable for young people and we have ratings for guidance. Mr Curry said while two games were recently refused an R18+ classification in Australia, regulators were simply using the "high-water mark" in relation to the guidelines, as happened when video game classifications were introduced 10 years ago.
