COLUMBIA, Mo., May 31 (UPI) -- People who play violent video games become less responsive to violence and are likely to become more aggressive, U.S. researchers suggest.
Bruce Bartholow of the University of Missouri says the study involved 70 young adult participants randomly assigned to play either a non-violent or a violent video game for 25 minutes. After the playing, the researchers measured brain responses as participants viewed a series of neutral photos, such as a man on a bike, and violent photos, such as a man holding a gun in another man's mouth.
