Abstract

Video game players outperform non-players on measures of basic attention and performance. Differences might result from exposure to video games or reflect other group differences. Research has suggested a causal link between video game experience and improved attentional skills (e.g., Green & Bavelier, 2003). We sought to replicate and extend these results. Expert/non-gamer performance was assessed on tasks tapping a wide range of abilities. Non- gamers played 20+ hours of an action video game, a puzzle game, or a real-time strategy game. Expert gamers and non-gamers differed on a number of basic cognitive skills: experts could track objects moving at greater speeds, better detected changes to objects stored in visual short-term memory, switched more quickly between tasks, and mentally rotated objects more efficiently. Strikingly, extensive video game practice did not substantially enhance performance for non- gamers on most cognitive tasks (except for a mental rotation task). Our results suggest that at least some differences between video game experts and non-gamers in basic cognitive performance result either from far more extensive video game experience or from pre-existing group differences in abilities that result in a self-selection effect.
