Across a series of recent studies, participants who played violent video games consistently showed increases in their aggressive behavior, both during and after playing. A study that linked violent video games to childhood aggression found that in every group tested, “children who had been exposed to more violence in video games became more aggressive over time than their peers who had had less exposure.” (Harding 1).
