trendspotter points out this research from Duke University: "Hours spent at the video gaming console not only train a player's hands to work the buttons on the controller, they probably also train the brain to make better and faster use of visual input, according to Duke University researchers (abstract). 'Gamers see the world differently,' said Greg Appelbaum, an assistant professor of psychiatry in the Duke School of Medicine. 'They are able to extract more information from a visual scene.' ... Each participant was run though a visual sensory memory task that flashed a circular arrangement of eight letters for just one-tenth of a second. After a delay ranging from 13 milliseconds to 2.5 seconds, an arrow appeared, pointing to one spot on the circle where a letter had been. Participants were asked to identify which letter had been in that spot. At every time interval, intensive players of action video games outperformed non-gamers in recalling the letter."
