Violent Video Games and Snack Attacks
Parents have long wondered whether violent video games encourage bad behavior in the kids who play them, but now a study suggests that such games may promote overeating. Researchers placed a bowl of M&Ms next to 172 high school students while they played either a nonviolent game or Grand Theft Auto, a game that rewards players for stealing cars, dealing drugs, and killing pedestrians on screen. Kids playing the violent game consumed an average of 39 candies during play, compared with nine in the group playing the nonviolent game. The researchers say these results suggest that violent video games promote decreased self-control.
