The GamePolitics blog has received excerpts from a new meta-analysis of the various studies attempting to link video game play with aggressive behavior. The study’s researcher, Christopher Ferguson has dissected 25 recent studies on video game violence and found that in general, while video game playing increased aggressive thoughts support for a link between game play and actual behavior was limited. Overall, those studies that employed better standards for measuring aggression showed lesser effects from video game play. Ferguson also found that publication bias played a large role in the studies; studies that showed stronger links seemed to be favored over those that did not.
