With respect to the contributions of digital games to improvement of cognitive processes, researchers suggest that regular practice has a significant influence on improving the performance related to basic visual skills (Li, Polat, Scalzo, & Bavelier, 2010); on the ability to perceive objects simultaneously (Dye & Bavelier, 2010; Feng, Spence, & Pratt, 2007); and on the ability to do more than one task at the same time (Boot, Kramer, Simons, Fabiani, & Gratton, 2008).
