When Gaming Is Good for You

Videogames can change a person's brain and, as researchers are finding, often that change is for the better.

Love them or hate them, online videogames are a treasure trove for researchers who are studying how all those keyboard taps, mouse clicks and joystick moves may affect behavior, perception and even cognitive skills. WSJ's Lee Hotz reports.
A growing body of university research suggests that gaming improves creativity, decision-making and perception. The specific benefits are wide ranging, from improved hand-eye coordination in surgeons to vision changes that boost night driving ability.

People who played action-based video and computer games made decisions 25% faster than others without sacrificing accuracy, according to a study. Indeed, the most adept gamers can make choices and act on them up to six times a second—four times faster than most people, other researchers found. Moreover, practiced game players can pay attention to more than six things at once without getting confused, compared with the four that someone can normally keep in mind, said University of Rochester researchers. The studies were conducted independently of the companies that sell video and computer games.
