You know, the benefits of videogames just keep adding up. According to a study published in Nature Neuroscience, video game training may help people improve contrast sensitivity, or the ability to differentiate between shades of gray. Among the two groups studied, the most improvement was noted among folks who played games which required precise, visually guided aiming actions, such as Call of Duty 2 and Unreal Tournament 2004. "When people play action games," said Daphne Bavelier, a professor of brain and cognitive sciences at the University of Rochester, "they're changing the brain's pathway responsible for visual processing. These games push the human visual system to the limits and the brain adapts to it, and we've seen the positive effect remains even two years after the training was over." Now that we've established that the Xbox can be part of a healthy lifestyle, it would be irresponsible of us not to play it more often.
