Pub Med has announced a new study on the effects of violent video game playing on persons with autism spectrum disorder, a study launched in response to some recent commentary that such game playing is more likely to negatively affect persons with ASD than those without the disorder. However, the authors report in their abstract that results “suggest that societal concerns that exposure to violent games may have a unique effect on adults with autism are not supported by evidence.”

It has been my contention for some time that violent video games are not causative of antisocial or violent behavior. Such behaviors have other roots, leaving only some measure of correlation (which is not causation) in its place. My view depends much on Social Cognitive Theory (Bandura) and the principal of self-agentic behavior, which is what led Bandura to leave the behaviorist school he originally advocated.
I would like to see someone investigate the possibility that playing violent video games may reinforce bad behavior in those predisposed to antisocial spectrum disorders, and not in those who lack such predispositions. But I’m afraid that experimental studies are likely to run afoul of guidelines for experiments with human subjects, leaving only population studies over time to try and fill the gap.
