Large meta-analysis finds video games linked to modest cognitive gains
A review of 133 studies confirms small but consistent improvements in memory, attention, and reasoning across game types and ages.
What to know
- A meta-analysis of 133 studies spanning 2005–2025 confirms video games improve memory, attention, and reasoning, but the gains are small and consistent across all ages and game types.
- Controlled trials, the gold standard, showed modest benefits (r=0.088); correlational studies suggested stronger associations, but causality remains uncertain.
- Researchers emphasize games are a potential cognitive aid, not a proven treatment, and call for more rigorous controlled trials to establish stronger evidence.

Meta-analysis of 133 studies confirms modest, consistent cognitive gains from gaming
A systematic review and meta-analysis synthesizing 133 studies (269 effect sizes, 14,245 participants) across correlational studies, between-group comparisons, and controlled trials found statistically significant positive associations between video game play and cognitive ability. Controlled trials showed small but significant benefits (r=0.088). Effects held across age, sex, cultural context, and game type, though researchers emphasized the gains are modest and called for further controlled trials.
“All three designs showed statistically significant, albeit generally weak, positive associations between video game play and cognitive ability.”

A 20-week study contrasted changes in cognitive performance between and electrical brain activity between groups of college students playing action or strategy video games (1 hr/day, n=33 and 35, respectively). Both groups had improved spatial attention, working memory, and executive function. Improvements in spatial attention and working memory…

Research finds different game genres enhance cognition in distinct ways
A 20-week controlled trial found that college students playing action or strategy games (1 hour per day) both improved in spatial attention, working memory, and executive function, with action game players showing greater gains in spatial attention and working memory.
“Both groups had improved spatial attention, working memory, and executive function. Improvements in spatial attention and working memory were greater for the action game players.”

background
Research shows thinner cerebral cortex linked to heavy gaming in adolescents — A study examining brain structure found that more time spent playing video games is linked to a thinner cerebral cortex in adolescents, marking one of several competing findings in the gaming-cognition research landscape.
