"Video games are now being used frequently through educational disciplines to train children and adults, in remedial situations, in business practices to train employees, and they're even being used by the military," Erickson told me.
Past research has shown that expert gamers tend to outperform novices on basic measures of attention and perception. Some studies have suggested that video-game training can help novices bridge the gap - while others indicated that the novices couldn't catch up after more than 20 hours of training. Read more...
