It was also found that the best gamers can make choices and act on them up to six times a second, four times faster than most people. People who play action-based games make decisions 25 per cent faster than others and are no less accurate, according to one study. Games also benefit a variety of brain functions, including decision-making. This is useful for driving at night, piloting a plane or reading X-rays. Vision is also improved, particularly telling the difference between shades of grey. A study of surgeons who do microsurgery in Boston found that those who played video games were 27 per cent faster and made 37 per cent fewer errors than those who didn't. Pre-school children who played interactive games such as the ones available on Wii have been shown to have improved motor skills, for example they can kick, catch and throw a ball better than children who don’t play video games. Games can help to develop physical skills. But now researchers are finding that games can actually change us for the better and improve both our body and mind. For years video games have been criticised for making people more antisocial, overweight or depressed.
