Read the following article on video games and violent behavior.

More and more of today's video games feature violent acts and weapons. Video games require gamers to pay close attention to the game because if you look away for a second, it could mean game over. As gamers become active participants in the game, some researchers believe that they begin to identify with the violent characters that they are portraying. Some researchers have found that this identification increases the gamer's ability to learn aggressive behaviors. Researchers argue that excessive exposure to violent video games may increase violent behaviors. A recent survey determined that over 70% of violent video games reward violence. If we think about behaviors, many are learned through reward. We teach our animals how to do certain behaviors by rewarding them; couldn't the same be true of gamers? We could argue that we are teaching gamers that violent behavior is good by rewarding the behavior. Either way, there certainly seems to be a connection between violence and video games.
