McGraw had recently read about research suggesting visual and rhythmic stimulation could improve reading and attention. Perhaps, she thought, this emerging theory about learning could be matched with the latest video game craze.
"There are a lot of ways to help kids read better," said McGraw, adding that few children find them interesting. "Kids naturally gravitate toward video games."
As part of the study, McGraw and colleagues recruited 62 sixth graders who suffered from attention deficit hyperactivity disorder (ADHD). First, the children were given a series of reading tests. Half the kids were then instructed to play Dance Dance Revolution for about an hour a week. The other children continued with their normal routine.
Just to ensure that no parent was taken aback by the unusual educational aid, McGraw said they chose the Disney version of the game, which includes a dancing Mickey Mouse and songs by Chubby Checker.
Three months later, the kids took the same reading tests again. The scores were largely the same for both groups, but those who played Dance Dance Revolution did slightly better with so-called receptive coding skills, the ability to immediately recall a word or series of numbers. This type of testing indicates greater focus and attention, a key issue for children with ADHD. The more times the kids played the game, the better they did.
"This was the real hot spot," said McGraw. By quickly matching their movements to visuals and music, children who play Dance Dance Revolution seem to strengthen the areas of the brain that are necessary for better memorization, McGraw explained. Since the game is exciting, these skills are more easily improved.
McGraw hopes to press ahead with her research to find a broader educational role for Dance Dance Revolution, as well as other video games.
"Everyone is playing them," she said, "And it's something schools can afford."
