Last year, Iowa State University researcher Douglas Gentile published a survey of American 8-to-18 year-olds which found 12% of boys were video-game addicted, having at least six symptoms out of 11, similar to a scale for gambling addiction. Yet only 3% of girls were video game addicts.

Robert Weis and Brittany C Cerankosky of Denison University measured a group of boys' academic baseline achievement and surveyed their parents and teachers as well. They then gave half the boys video-game units. Boys receiving the video-game stations experienced an academic nosedive. The control group of boys without video games continued with solid schoolwork.

games provide information when it is needed, rather than all at once in the beginning, and also provide an environment that is "pleasantly frustrating" because the tasks are challenging but achievable.

"We tend to teach science, for example, by telling you a lot of stuff and then letting you do science. Games teach the other way. They have you do stuff, and then as you need to know information, they tell it to you."
