"Playing quick paced action video games such as Call of Duty or Assassin's Creed can boost your ability to learn new motor skills, researchers have found. The University of Toronto study discovered people who play action video games such as Call of Duty or Assassin's Creed seem to learn a new sensorimotor skill more quickly than non-gamers do. With such skills, an individual generally moves from novice performance, characterized by a low degree of coordination, to expert performance, marked by a high degree of coordination. As a result of successful sensorimotor learning, one comes to perform these tasks efficiently and perhaps even without consciously thinking about them."
