What was the results of the Bushman & Anderson study on the effects of violent video game play on aggression.
A critic argues that this study does not necessarily provide strong evidence for the claim that violent video game play causes aggression, because there may have been more aggressive or impulsive people in the violent video game group than in the nonviolent video game group (the observed results could be due to the personalities of the research participants, not the video game play). is this a reasonable criticism?
