A new systematic review and meta-analysis published in Acta Psychologica has synthesized two decades of research on the cognitive effects of video games, finding modest but statistically significant benefits. The study analyzed 133 studies involving 14,245 participants, covering research published between January 2005 and August 2025.
Study Design and Quality Assessment
The researchers conducted three separate meta-analyses: one on correlational studies, one comparing gamers to non-gamers, and one on controlled trials. They assessed study quality using the Joanna Briggs Institute Critical Appraisal Checklist, rating 69.93% of studies as medium quality, 25.56% as high, and 4.51% as low. Cognitive outcomes were grouped into five domains: memory, spatial ability, visual attention, cognitive control, and intelligence.
Key Findings Across Meta-Analyses
The correlational analysis revealed a statistically significant but weak positive correlation between video game play and overall cognitive ability, with the strongest association found for memory. The authors note, “In the meta-analysis of correlational studies, the findings revealed a statistically significant, yet weak, positive correlation between video game play and overall cognitive ability. This indicates that a longer duration of video game play may be associated with higher scores on cognitive assessments.” They add, “When examining specific cognitive domains, a significant association was found only for memory, suggesting that video game play may have a more consistent association with skills related to memory. One possible interpretation of this association is that individuals who invest more time in gaming engage in frequent and sustained recruitment of memory-related skills during gameplay.”
In comparisons between gamers and non-gamers, gamers showed a small overall advantage, particularly in spatial ability, visual attention, cognitive control, and intelligence. Controlled trials—which provide the strongest causal evidence—showed the smallest effects, with memory being the only domain demonstrating clear significant improvement.
Context and Skepticism
The authors acknowledge that some researchers remain skeptical about the cognitive benefits of video games, citing the problem of “near-transfer” effects. They explain, “Some researchers remain skeptical about the positive cognitive effects of playing video games, arguing that video game play typically produces only ‘near-transfer’ effects. This means improvements are largely confined to the video game itself or highly similar contexts, with limited evidence supporting the enhancement of ‘far-transfer’ cognitive abilities applicable to everyday life.”
Moderator Analyses
The team conducted moderator tests to examine whether factors such as gender, age, culture (Eastern vs. Western), health status, intervention duration, or game type influenced the results. They found little evidence that these factors strongly affected the outcomes, suggesting the cognitive benefits of video games are relatively consistent across different populations and conditions.
Implications
This comprehensive analysis provides the most up-to-date synthesis of the evidence, indicating that while video games are not a panacea for cognitive enhancement, they do offer small, measurable benefits—particularly for memory and spatial skills. The findings support the idea that the interactive nature of video games may engage cognitive processes in ways that passive entertainment does not.
