AMES, Iowa -- Like other fathers and sons, Douglas Gentile and his father have spent many hours arguing about video games. What makes them different is that Douglas, an Iowa State University assistant professor of psychology, is one of the country's top researchers on the effects of media on children. His father, J. Ronald Gentile, is a leading researcher on effective teaching and a distinguished teaching professor emeritus of educational psychology at the University of Buffalo, State University of New York.

Through their discussions, they realized that video games use the same techniques that really great teachers use.

The Gentiles decided to test that hypothesis. Through a study of nearly 2,500 youths, they found that video games are indeed effective teaching tools. Students who played multiple violent video games actually learned through those games to produce greater hostile actions and aggressive behaviors over a span of six months.
