Playing video games moderately improves various mental skills, allowing players to process information and memorize details more effectively. A recent comprehensive review of dozens of studies found that gaming provides modest performance benefits across a variety of age groups and study designs. The study was published in the journal Acta Psychologica.
Cognitive ability refers to a person’s ability to receive, process, store, and retrieve information. This broad category includes everyday mental functions such as paying attention, visualizing objects in physical space, and remembering past events. These skills predict a wide range of life outcomes, from academic success to general health. Mental sharpness tends to decline as we age, so researchers are looking for ways to preserve and enhance brain function throughout the lifespan.
Cognitive training involves repeating standardized mental tasks to strengthen specific brain abilities. Video games are considered the perfect medium for this type of training because they feature structured goals, adjustable difficulty settings, and instant feedback. Rumei Zhao and colleagues at Shanghai Normal University investigated whether spending time in the digital world actually improves everyday mental performance. Zhao, along with co-authors Xuechen Ding and Junyi Li, analyzed data covering a wide range of game genres.
The idea that gaming changes the brain is related to neuroplasticity. Neuroplasticity is the brain’s ability to reorganize its physical connections in response to new experiences. Some researchers advocate the “learning to learn” theory. This concept suggests that people who navigate difficult game mechanics can refine common problem-solving strategies and transfer them to real-world situations. Other experts remain skeptical about these benefits, arguing that playing a particular video game usually only makes you better at that particular game.
To resolve some of these conflicting ideas, the research team pooled data from 133 independent studies. This process resulted in a large sample of 14,245 participants. The researchers divided the collected literature into three different mathematical analyzes based on how the original study was designed.
Their first analysis looked at correlational studies that simply looked at people’s gaming habits and compared those habits to their scores on psychological assessments. The research team found a weak but positive association between playing games and overall mental performance. When analyzing specific skills, memory was the only area that showed a reliable relationship with game time.
It’s quite possible that gamers will frequently utilize memory-driven skills during their sessions. However, this type of research cannot prove that games improve memory. It’s equally possible that people with naturally strong memories are drawn to games in the first place.
The second analysis focused on direct comparisons between avid gamers and non-gamers. In these studies, experienced players generally performed better than non-players on a variety of cognitive tests. The gamers showed superior performance across multiple areas, including spatial awareness, visual attention, and intelligence. Spatial abilities are mental skills used to visualize and rotate objects in the mind’s eye.
Scientists test spatial awareness abilities by having participants look at folded paper shapes and mentally unfold them to match a distinct target. Gamers also showed better cognitive control than their non-gaming peers. Cognitive control acts as the brain’s command center, helping people suppress impulsive behavior and smoothly switch between different rules and tasks. In a laboratory setting, this is often measured by observing how quickly a subject can stop a planned physical movement when a red light flashes on the screen.
Video games often require concentration and quick reactions for long periods of time. Replaying these may facilitate the neural adaptations needed to efficiently process chaotic information. The third analysis evaluated a controlled trial in which researchers had people play video games for a period of time and then measured changes in mental performance. This experimental approach provides the strongest evidence of cause and effect.
The researchers found that the video game intervention led to small improvements in overall mental performance compared to alternative activities and a rest control group. When examining specific skills, memory once again stood out as having benefited in isolation. Researchers believe that the rich nature of virtual environments may play a major role in supporting memory formation. Modern games often feature vast simulated worlds, and exploring these digital maps can be just as taxing on the brain as navigating physical space.
The game also gives you frequent and predictable rewards, such as completing a level or finding hidden items. This constant loop of action and reward is somewhat unique to interactive media and distinguishes gaming from passive entertainment like watching television. These in-game rewards trigger the release of dopamine in the brain. Dopamine is a chemical messenger often associated with pleasure and motivation, but it also acts as an essential element in cementing new memories.
The release of dopamine during engaging activities helps the brain recognize that certain information is worth retaining. This chemical boost may promote more focused practice while strengthening the neural circuits responsible for long-term memory consolidation. The samples analyzed were very diverse and covered all age groups, from children to the elderly. Participants included healthy individuals as well as clinical participants such as patients with depression and multiple sclerosis.
Some experts suggest that implementing digital interventions may increase the psychological adaptability of clinical populations. Designing games specifically for these groups could provide customized and easily tracked rehabilitation exercises. The scientists also examined whether external variables changed the magnitude of psychological benefits. They categorized interventions by specific game genres, including real-time strategy titles, puzzle games, motion-sensing activities, and shooter games.
Although past research suggests that certain genres are better at increasing visual attention, game type did not significantly influence the results of this extensive analysis. Other variables such as participants’ gender, age group, and cultural background did not significantly alter the results. The research team used established academic guidelines to assess the quality of the included studies. These checklists examine how well studies define participant groups, measure their variables, and handle confounding background data.
A study may have a docking point if it was unable to use an appropriate control group or if the evaluators knew which participants were receiving the gaming intervention. Based on these ratings, the majority of studies were rated as being of moderate quality. Few met the absolute highest standards of experimental rigor. Excluding lower-quality studies from mathematics did not significantly change the overall conclusion.
This consistency gives researchers confidence that the modest psychological benefits associated with gaming are not just a statistical illusion. Still, the reliance on moderate quality evidence means that these results should be interpreted with some caution. Researchers measured cognitive skills in a variety of ways, with some relying on unvalidated self-report surveys instead of objective computer tests. The included studies also varied widely in intervention protocols.
Some participants in the experiment played the game for just a few minutes, while others played for dozens of hours over several weeks. This discrepancy makes it difficult to establish the ideal dosage for digital brain training. A lack of long-term tracking data also prevents researchers from knowing whether the psychological benefits disappear after a person turns off their gaming console. A more rigorous experimental setup that tracks participants over time will be needed to see if gaming offers durable protection against age-related mental decline.
For now, existing data is prompting a shift in how society views digital recreation. Although games are not meant to replace traditional learning or physical exercise, they can serve as an attractive supplement to keeping your mind active.
