In the first of the current studies, researchers had 320 college students play either violent or nonviolent video games. After about 20 minutes of playing, a fight was staged outside the lab in which one of the actors appeared to be left moaning from the pain of a sprained ankle. The participants who played violent video games took 73 seconds compared to respond to the "victim," compared to the 16 seconds that the non-violent players took. Not only this, but the violent gamers also took notice the commotion less often than did the non-violent players; when they did, they were less likely than the non-violent gamers to rate it as serious.'[T]hese studies clearly show that violent media exposure can reduce helping behavior.'
