Videogames Affirm Violence Among Kids?

Thanks to Mainichi.co.jp for their report on a new Japanese survey claiming young videogame-playing children are more violent. According to the Ochanomizu University study, "The more elementary school students play video games, the more likely they are to get irritated and want to hit others." However, the story also points out that "Another study on British children also released at the International Simulation and Gaming Association meeting gave different results, finding that those who preferred violent games more were not as aggressive in their actual lifestyles", leading to the inevitable conclusion that there's no definite answer - though that Japanese survey did suggest that "In video games it is common for players to be awarded 'points' for violent actions, and there may be aspects in which violence is taken affirmatively."
