... is linked to insults, not abuse when growing up.
I won't repeat everything I posted elsewhere, but really, that's the stupidest research I've heard of in a long time. First of all, starting with calling a version of Half Life 2 where enemies evaporate "non-violent". So, if there's no blood it's not violence? If you just disintegrate people that's a non-violent game? That's such a basic problem with definitions that I feel that the researchers should be taken out and evaporated non-violently.
Then there's the conclusion. Sure, people can get angry when they are frustrated. You don't have to be a genius to know that. A more interesting question would be how well people deal with that frustration. Do players of violent game tend to have worse control of their temper in this respect than others? That would be more interesting than the stupid conclusions here.
(And I'd like to apologise to the researchers, I haven't read the research paper, just the articles on various sites, and it's possible that it's only the writers of these editorials who are jumping to conclusions. However I'm sure that the "non-violent Half life 2" is part of the original article, and as such I can believe that the rest of the stupidity also exists there.)
