OMAHA, Neb. -- Playing video games increases aggression in some children and young adults and normalizes killing, some doctors said.
Research suggests that violent video games can make children feel different. A brain scan of a teenager who has just played what was deemed a nonviolent video game was compared to the scan of a teen who had just spent 30 minutes playing a violent game. Indiana School of Medicine researchers said highlighted areas in the brains showed increased activity in the areas involved in emotional arousal.
