There is evidence that playing certain types of video games does in fact improve reflexes. Video games have been shown to improve reaction times useful in a number of everyday skills, from driving to multitasking.
Playing action-oriented video games can train the brain to make correct decisions faster, according to a study performed at the University of Rochester. The scientists tested two groups of young adults, none of whom were regular video game players. The first group played fifty hours of action-oriented games, while the second group played slower-paced games. The first group showed faster response times afterward in tests designed to measure reactions to visual and auditory stimuli. It is believed that because video gamers' brains have been trained to collect these kinds of stimuli efficiently, they are able to process information and make decisions faster than non-gamers.
