How Video Games Affect Memory
A strange thing can happen after you have spent enough time playing a video game.
You may forget the name of someone you met earlier in the day, yet remember exactly where a hidden item was located on a map you explored only once. You may have trouble recalling what you had for lunch, but somehow remember which doorway an opponent disappeared through several minutes ago.
That raises an interesting question.
Can playing video games actually improve memory?
The answer is more complicated than a simple yes or no.
Video games do not appear to improve every type of memory in the same way. However, depending on the type of game and the way it is played, gaming may influence specific cognitive abilities such as selective attention, visuospatial attention, working memory, spatial memory, and cognitive control.
At the same time, gaming can work in the opposite direction if it regularly cuts into sleep, physical activity, studying, or other important parts of daily life.
To understand how video games affect memory, we first need to stop treating “memory” as one single ability.
Video Games and Memory: Memory Is Not Just One Skill
When people say they have a “good memory,” they are usually combining several different mental abilities into one phrase.
Remembering a phone number for a few seconds is not the same process as remembering a childhood event.
Finding your way through an unfamiliar neighborhood is also different from recalling a list of words.
Several cognitive systems are especially relevant when researchers study gaming.
| Cognitive Function | What It Does | Example During Gaming |
|---|---|---|
| Selective attention | Focuses on relevant information while ignoring distractions | Finding an opponent among many moving objects |
| Sustained attention | Maintains focus over time | Following a long mission or extended match |
| Working memory | Holds and manipulates information for a short period | Remembering enemy locations while planning the next move |
| Spatial memory | Stores locations and relationships between places | Remembering a map, route, or item location |
| Cognitive control | Helps switch attention and suppress irrelevant responses | Ignoring distractions and reacting to an important cue |
| Long-term memory | Stores information for extended periods | Remembering game rules, strategies, and maps weeks later |
This distinction matters because research does not suggest that gaming simply raises a person’s overall “memory score.”
Instead, some types of gaming appear to place repeated demands on particular mental systems.
And the systems that are used repeatedly are the ones most likely to show measurable changes.
Video Games May Affect Attention Before They Affect Memory
Memory begins before information is actually stored.
First, the brain has to notice the information.
In cognitive psychology, this early stage is often called encoding.
If you never pay attention to something in the first place, the brain has much less information available to store.
Imagine walking through a shopping mall while staring at your phone.
Someone may later ask what store you passed five minutes earlier, and you might have no idea.
That does not necessarily mean your memory failed.
The information may never have been properly encoded because your attention was somewhere else.
Fast-paced video games constantly challenge this first stage of memory.
In many action games, players must track enemies, movement, terrain, objectives, ammunition, teammates, and visual warnings at the same time.
The brain has to decide what matters and what can be ignored.
This repeatedly engages selective attention and visuospatial attention.
Research on action video game players has often found differences in the way experienced players distribute visual attention, especially when information appears rapidly across different areas of the screen.
That is one reason the connection between gaming and memory often begins with attention.
Better selection of relevant information can make later memory formation easier because the brain has better information to work with.
Do Action Video Games Really Improve Attention?
Action games are among the most studied genres in gaming and cognition research.
A major meta-analysis published in Psychological Bulletin examined the relationship between action video game experience and perceptual, attentional, and cognitive abilities.
Experienced action gamers often performed better than non-gamers on certain cognitive tasks.
However, there is an important detail.
The differences were usually larger in studies that simply compared existing gamers with non-gamers.
The effects were smaller in controlled training studies where researchers assigned people to play games and then measured how their abilities changed.
That distinction matters.
People who already have strong visual attention may simply be more likely to enjoy fast-paced games.
In other words, researchers must separate selection effects from training effects.
Did gaming improve the skill?
Or did people who already had the skill choose the game?
Training studies suggest that gaming may produce genuine improvements in certain attentional abilities, but the effects are usually much more modest than dramatic headlines suggest.
Top-down attention is one area researchers often discuss.
This is the ability to deliberately direct attention toward information that matters for a current goal.
For example, a player may ignore explosions, background animation, and other visual noise while searching for one specific target.
That is very different from saying that action games make a person “smarter.”
The effect appears to be more specific.
Working Memory Is Constantly Used During Gaming
Working memory is one of the most important cognitive systems involved in complex gameplay.
Working memory allows you to hold information in your mind temporarily while using it.
A common real-world example is driving after a GPS tells you:
“Turn right in 300 feet.”
For a short time, you have to retain that instruction while also monitoring traffic, signs, pedestrians, and the road.
Games often require the same type of mental juggling.
Imagine a strategy game.
You may need to remember that you have 800 units of a resource, that a new structure costs 500, that an opponent is approaching from the north, and that another unit will become available in 30 seconds.
You are not simply memorizing those details.
You are constantly updating and using them.
This is called working memory updating.
The same process occurs in shooters, role-playing games, real-time strategy games, and many multiplayer games.
A player might remember where an opponent was last seen while monitoring ammunition, health, teammate positions, and the next objective.
Research on video-game-based cognitive training has found some evidence that working memory updating can improve after certain forms of training.
However, the results are not consistent across every game, age group, or study.
That means it is more accurate to say that gaming may train certain components of working memory rather than claiming that video games improve memory in general.
Why Spatial Memory Is So Important in Video Game Research
Spatial memory is one of the most interesting areas in the gaming literature.
Spatial memory helps us remember where things are and how different locations are connected.
It allows you to remember where you parked your car, navigate a building, or find your way back through a neighborhood.
A brain structure called the hippocampus is deeply involved in both memory formation and spatial navigation.
Many modern 3D games require players to create what neuroscientists sometimes call a cognitive map.
You learn that one hallway connects to another room.
You remember that a staircase leads to a higher level.
You recognize that taking one route eventually loops back to a location you visited earlier.
This resembles what happens when you explore a real city for the first time.
At first, every street seems unfamiliar.
After repeated exploration, the brain begins organizing the environment into a mental map.
Some video games may require a surprisingly similar form of spatial learning.
A Real Research Example: Super Mario 64 and the Hippocampus
One frequently discussed study examined older adults between the ages of 55 and 75.
Participants were placed into different groups.
One group trained with the 3D platform game Super Mario 64.
Another learned piano using computer-based instruction.
A third group did not complete the same type of structured training.
Participants in the game group spent months learning and navigating a three-dimensional environment.
Researchers reported increases in gray matter within the hippocampus in the gaming group when comparing brain scans taken before and after training.
Changes in other brain regions were also observed in the music group and game group.
This study is fascinating, but it also needs context.
The gaming group was small, so the findings should not be treated as proof that playing a specific game automatically enlarges the hippocampus.
What the study does suggest is more interesting.
Even in later adulthood, learning a new spatial environment may be associated with neuroplasticity.
Neuroplasticity refers to the brain’s ability to change in response to experience.
The important factor may not be the fact that a person was “playing a game.”
The important factor may be the type of mental problem the brain was repeatedly solving.
The Type of Cognitive Challenge May Matter More Than the Game Genre
Gaming research used to focus heavily on genre.
Researchers compared action games, strategy games, puzzle games, casual games, and other categories.
That approach is useful, but it has limitations.
Two games in the same genre can demand very different mental skills.
One action game may require intense visual tracking.
Another may rely heavily on memorizing a map.
A strategy game may require long-term planning, while another may become highly repetitive once the player learns a fixed strategy.
Recent research has increasingly looked at game mechanics and cognitive demands rather than genre labels alone.
A meta-analysis of video-game-based cognitive training suggested that specific game features may help explain cognitive outcomes better than broad genre categories.
That makes sense.
The brain does not know whether a game has been labeled “action,” “strategy,” or “adventure” by a store.
The brain responds to the tasks it repeatedly performs.
Kori’s Midway Thought
The more I look at this research, the less useful it seems to divide games into only two categories: “good for the brain” and “a waste of time.”
Chess does not improve every kind of memory simply because it requires thinking, and video games are no different.
If a game repeatedly forces you to explore unfamiliar environments, you are using spatial memory. If it requires you to track rapidly changing information, attention and working memory are under pressure.
What seems to matter most is not simply whether someone plays games, but what the brain is repeatedly being asked to do while playing them.
Does Better Gaming Performance Transfer to Real Life?
This is where one of the most important concepts in cognitive training appears.
It is called transfer.
Researchers often distinguish between near transfer and far transfer.
Near transfer occurs when practice improves performance on a similar task.
For example, repeatedly tracking moving objects in a fast-paced game might improve performance on another visual tracking task.
Far transfer is much more ambitious.
It would mean that gaming improves abilities in areas that are very different from the activity being practiced.
For example, someone might claim that playing video games improves grades, general intelligence, job performance, or memory in everyday life.
Far transfer is much harder to demonstrate.
Many cognitive training studies find that people become better at tasks that resemble the skill they practiced.
That is not surprising.
What is less certain is whether those improvements spread broadly across unrelated areas of life.
So if someone becomes extremely good at remembering the layout of a video game map, we should not automatically assume that person will also remember names, appointments, vocabulary, or school material better.
One-line tip: Instead of asking, “Is this game good for the brain?” ask, “What information does this game repeatedly force my brain to notice, remember, update, and use?”
What Does the Newer Large-Scale Research Show?
A 2026 meta-analysis published in Acta Psychologica reviewed research published between 2005 and 2025.
The analysis included 133 studies, more than 14,000 participants, and hundreds of reported effect sizes.
Researchers examined relationships between video game experience and several cognitive abilities, including memory, spatial ability, visual attention, cognitive control, and intelligence-related measures.
The overall pattern was positive.
Gaming was associated with better performance in several cognitive domains.
However, the average effects were small.
That is a very important distinction.
The evidence does not suggest that gaming transforms memory or intelligence.
At the same time, it would also be inaccurate to say that gaming has no measurable relationship with cognitive performance.
The current evidence sits somewhere in the middle.
Certain forms of gaming appear to be associated with small but meaningful changes in specific cognitive skills.
More Gaming Does Not Mean More Memory Improvement
If some gaming is cognitively demanding, it may seem logical to assume that playing more must be even better.
That is not necessarily true.
One reason is automaticity.
When you begin a new game, almost everything requires active thought.
You have to learn the controls, understand the rules, remember the map, recognize patterns, and decide what to do next.
After hundreds of hours, many of those decisions become automatic.
The brain may no longer be solving the same number of new problems.
Cognitive load decreases as skills become familiar.
This is similar to many forms of training.
A beginner learning piano must think carefully about every note.
An experienced musician can perform familiar sequences with much less conscious effort.
Gaming can work the same way.
From a cognitive perspective, new challenges may matter more than endlessly repeating familiar ones.
Gaming Can Also Interfere With Memory
There is another side of the discussion that should not be ignored.
The cognitive demands of a game and the lifestyle effects of gaming are two different things.
Sleep is one of the biggest examples.
Memories are not fully processed only while we are awake.
After learning, the brain continues stabilizing and reorganizing information.
This process is called memory consolidation.
Sleep plays an important role in that process.
If someone regularly stays up late gaming and loses one or two hours of sleep, the cognitive benefits of the game may be offset by the effects of sleep deprivation.
Research has linked late-night or prolonged gaming with delayed sleep, shorter sleep duration, fatigue, and poorer next-day cognitive performance in some groups.
This does not mean that playing a game at night automatically damages memory.
The problem is usually behavioral.
A 45-minute gaming session that ends at a reasonable time is very different from playing until 3 a.m. before work or school.
Play Style May Matter More Than Total Play Time
Two people can both play video games for two hours and have completely different cognitive experiences.
One person may spend those two hours exploring a new 3D environment, learning unfamiliar mechanics, remembering locations, and adjusting strategies.
Another may repeat the same familiar task with very little new learning.
The number of hours is identical.
The mental workload is not.
| Play Pattern | Possible Cognitive Demand |
|---|---|
| Exploring unfamiliar 3D environments | Spatial memory and cognitive mapping |
| Tracking fast-moving targets | Selective and visuospatial attention |
| Managing several changing variables | Working memory and cognitive control |
| Building long-term strategies | Planning and decision-making |
| Repeating highly familiar actions | Lower levels of new cognitive challenge |
| Playing late into the night | Possible disruption of sleep and memory consolidation |
| Gaming that replaces exercise, study, or social activity | Possible indirect effects on cognitive health |
This is why studies that look only at “hours played per week” may miss important details.
What you play, how you play, and what the gaming session replaces in your daily life may all matter.
What Parts of the Brain Are Often Discussed in Gaming Research?
Several brain regions frequently appear in studies of gaming and cognition.
The hippocampus is strongly involved in spatial memory and the formation of new memories.
The prefrontal cortex plays an important role in working memory, inhibition, planning, and decision-making.
The parietal cortex contributes to spatial processing and visual attention.
Visual and motor areas are also heavily involved because games constantly connect perception with action.
Players repeatedly move through a cycle that looks something like this:
See information.
Interpret it.
Remember what matters.
Choose an action.
Observe the result.
Update the plan.
This is sometimes described as a perception-action loop.
Games can repeat this loop hundreds or even thousands of times during a single session.
That repeated interaction is one reason video games have attracted so much attention from cognitive scientists.
Still, claims about the brain should be made carefully.
Finding a change in one brain region does not mean that every player will experience the same structural or functional change.
Brain imaging studies can differ considerably depending on the game, population, training period, and research method.
How to Use Games as a More Meaningful Cognitive Activity
If your goal is to use gaming as one form of cognitive stimulation, challenge matters more than simply accumulating hours.
For spatial memory, try navigating without relying constantly on map markers.
For strategy games, create your own plan instead of copying an optimized strategy from a guide.
For puzzle games, move to unfamiliar problem types rather than replaying the same comfortable levels.
Games that require you to continually learn, adapt, remember, and make decisions are likely to demand more from the brain than repetitive gameplay that has become almost automatic.
But gaming should remain part of a larger cognitive lifestyle.
Sleep, exercise, reading, learning new skills, social interaction, and real-world problem-solving are all important.
If a supposedly “brain-training” gaming routine regularly costs you sleep, the tradeoff may not make much sense.
Video Games Can Challenge Memory, but They Are Not a Magic Brain Workout
The research on gaming and cognition is genuinely interesting.
Action games have been associated with differences in visuospatial attention.
Some game-based training studies have found improvements in specific aspects of working memory.
Three-dimensional navigation games may strongly engage spatial memory systems.
Certain studies have also reported brain changes related to learning and neuroplasticity.
But the effects are usually selective.
A large 2026 meta-analysis found positive relationships between gaming and several cognitive abilities, but the average effects were small.
That is probably the best way to understand the evidence.
Video games are not a universal memory enhancer.
They are complex environments that can repeatedly exercise particular cognitive skills.
A game that requires navigation may challenge spatial memory.
A fast visual game may challenge attention.
A strategy game may place greater demands on working memory and cognitive control.
The brain adapts less to the word “gaming” than to the actual problems it repeatedly has to solve.
Video games can repeatedly engage specific cognitive skills such as attention, working memory, and spatial memory. But memory is not determined by gaming alone. How well we remember information also depends on attention during encoding, sleep and memory consolidation, repeated retrieval, physical activity, stress, and the way we organize new information.
If you want to go beyond gaming and understand how to learn information more efficiently and remember it for longer, 「Memory Improvement: The Brain Science of Learning Faster and Remembering Longer」 explains how memories are formed, strengthened, and retrieved, along with practical strategies that can be used in everyday learning.
Kori’s Take
After looking through the research, I think the biggest mistake is focusing only on how many hours someone plays.
The more useful question is what the brain is doing during those hours.
If a player is exploring unfamiliar spaces, tracking several pieces of information, changing strategies, and making decisions under pressure, that is clearly an active cognitive experience.
But if the same gaming habit pushes bedtime later every night and consistently reduces sleep, the overall effect can look very different.
Video games are neither a memory supplement nor automatically harmful to the brain.
Used in moderation, the right kind of game can be one more environment where attention, working memory, spatial memory, and problem-solving are repeatedly exercised.
The key is not simply playing more.
The key is continuing to learn.

How Video Games Affect Memory Q&A
1. Can playing video games actually improve memory?
Some forms of gaming may improve specific cognitive functions related to memory, but they do not appear to improve every type of memory equally.
The strongest evidence tends to involve abilities such as visuospatial attention, spatial processing, and certain components of working memory.
Improving at a particular gaming-related cognitive task also does not guarantee that everyday memory will improve to the same degree.
2. What type of video game is best for memory?
There is no single game that researchers can confidently call the best game for memory.
The cognitive demands of the game matter more.
Games that require spatial navigation, active planning, rapid visual search, working memory, strategy changes, and continuous learning may provide more cognitive stimulation than highly repetitive games.
The key question is what mental process the game repeatedly requires.
3. Does playing more video games lead to better memory?
Not necessarily.
Once a game becomes extremely familiar, many actions become automatic and require less active cognitive processing.
Excessive gaming can also reduce sleep or replace exercise, studying, and other beneficial activities.
For cognitive stimulation, continuing to face new problems and maintaining healthy sleep may matter more than simply increasing total gaming hours.
