A team of Australian researchers recently conducted a study to determine what effect -- if any -- late-night violent gaming sessions have on a young person's sleep cycle. Two groups of teenage boys were either made to play 50 minutes of Call of Duty 4: Modern Warfare or watch March of the Penguins while lying in bed. The results showed that the group who played Modern Warfare took only a few minutes longer to fall asleep than those watching the movie, causing the researchers to think presleep gaming's negative effects "may be more modest than previously thought."
