Video games is good for your brain. Whether playing video games has negative effects is something that has been debated for 30 years, in much the same way that rock and roll, television, and even the novel faced similar criticisms in their time.Purported negative effects such as addiction, increased aggression, and various health consequences such as obesity and repetitive strain injuries tend to get far more media coverage than the positives.In a series of experiments on small numbers of gamers (10 to 14 people in each study), the researchers reported that gamers with previous experience of playing such action video games were better at perceptual tasks such as pattern discrimination than gamers with less experience.In another experiment, they trained gamers who had little previous experience of playing action games, giving them 50 hours practice. It was shown that these gamers performed much better on perceptual tasks than they had prior to their training.
