Researchers at Iowa State University have determined that kids who play violent video games become more aggressive over time.

Researcher Douglas Genile was part of the team that tracked young video game players over a three year period.

"When kids play pro-social games, they learn from those and end up being more helpful and cooperative.  If they play violent video games, they learn from that and end up being more willing to behave aggressively when provoked."

The study concluded that the video games kids play directly correlates to behavior in the real world.
