Video gaming, the experience of playing electronic games, has shown several benefits for human health. Recently, numerous video gaming studies showed beneficial effects on cognition and the brain. A systematic review of video gaming has been published. However, the previous systematic review has several differences to this systematic review.

Around the world, video gamers spend billions of hours per week in front of their screens. Some scientists have researched the impact of video games. Here, find our how they affect the brain and behavior.
At a glance, more than 150 million people in the United States play video games regularly, or for at least 3 hours per week. The average American gamer is a 35-year-old adult, with 72 percent of gamers aged 18 or older. For video game use by children, most parents – 71 percent – indicate that video games have a positive influence on their child’s life.
Video game sales continue to increase year on year. In 2016, the video game industry sold more than 24.5 billion games – up from 23.2 billion in 2015, and 21.4 billion in 2014.
The top three best-selling video games of 2016 were Call of Duty: Infinite Warfare, Battlefield 1, and Grand Theft Auto V. These games fall into the first-person shooter or action-adventure genres – the top two genres, accounting for 27.5 percent and 22.5 percent of sales, respectively. First-person shooter and action genres often stand accused of stirring aggression and causing violence and addiction.
A growing body of evidence, however, shows that video gaming can affect the brain and, furthermore, cause changes in many regions of the brain.
Scientists have recently collected and summarized results from 116 scientific studies to determine how video games can influence our brains and behaviors. The findings of their review were published in Frontiers in Human Neuroscience.
“Games have sometimes been praised or demonized, often without real data backing up those claims. Moreover, gaming is a popular activity, so everyone seems to have strong opinions on the topic,” says Marc Palaus, first author of the review.
By looking at all research to date, Palaus and team aimed to observe whether any trends had emerged with regard to how video games impact the structure and activity of the brain. A total of 22 of the reviewed studies explored structural changes in the brain and 100 studies analyzed changes in brain functionality and behavior.
Results of the studies indicate that playing video games not only changes how our brains perform but also their structure.
For example, video game use is known to affect attention. The studies included in the review show that video game players display improvements in several types of attention, including sustained attention and selective attention. Furthermore, the regions of the brain that play a role in attention are more efficient in gamers compared with non-gamers, and they require less activation to stay focused on demanding tasks.
A team of researchers from the Florida State University has stated that people should be skeptical of adverts that promote an increase in the performance of the brain that results from brain training games. They have said that science does not support these claims.
“Our findings and previous studies confirm there’s very little evidence these types of games can improve your life in a meaningful way,” says Wally Boot, associate professor of psychology, an expert on age-related cognitive decline.
People are increasingly under the impression that brain-training apps will safeguard them against memory loss or cognitive disorders.
Researchers tested whether playing brain-training games enhanced the working memory of players and thus improved other cognitive abilities, including reasoning, memory, and processing speed – a process scientists call “far transfer.” However, this was not the case.
“It’s possible to train people to become very good at tasks that you would normally consider general working memory tasks: memorizing 70, 80, even 100 digits,” explains Neil Charness, professor of psychology and a leading authority on aging and cognition.
“But these skills tend to be very specific and not show a lot of transfer. The thing that seniors, in particular, should be concerned about is, if I can get very good at crossword puzzles, is that going to help me remember where my keys are? And the answer is probably no,” he adds.
In contrast, a study published in Nature found that through the use of a specially designed 3-D video game, cognitive performance could be improved in older adults and some of the adverse effects on the brain associated with aging, reversed.
Scientists at the University of California-San Francisco (UCSF) clarify that this provides a measure of scientific support in the brain fitness arena – criticized for lacking evidence – that brain training can stimulate meaningful and lasting changes.
After 12 hours of training over the period of a month, study participants aged between 60 to 85 years improved performance on the game that surpassed that of individuals in their 20s playing the game for the first time. Moreover, two other significant cognitive areas were improved: working memory and sustained attention. These skills were maintained 6 months after completion of their training.
“The finding is a powerful example of how plastic the older brain is,” says Dr. Adam Gazzaley, Ph.D., UCSF associate professor of neurology, physiology and psychiatry and director of the Neuroscience Imaging Center. Dr. Gazzaley notes that it is encouraging that even a little brain training can reverse some of the brain decline that occurs with age.
A recent study conducted by neurobiologists at the University of California-Irvine (UCI) found that playing 3-D video games could also boost the formation of memories. Participants were allocated to either a group that played video games with a 2-D environment or a 3-D environment. After playing the games for 30 minutes per day for 2 weeks, the students were given memory tests that engaged the brain’s hippocampus.
The participants in the 3-D group significantly improved their memory test scores compared with the 2-D group. The 3-D group’s memory performance increased by 12 percent – the same amount that memory performance usually declines by between 45 and 70 years of age.
There seems to be a strong preponderance of reported decreases of brain function in studies in which the task performed during measurement was closely related to the video game that was actually trained (n=6) 2, 9, 30, 34, 35, 37, 40 The direction of these results – namely decreases in brain activity due to training when the trained task is performed – are in line with previous studies on ...

Oct 24, 2023 · The extent to which video game play alters the brain and cognition depends on many factors, such as age, amount of time spent playing video games, and what kind of video games are played. For instance, while playing video games does seem to have at least a small positive effect across all ages, video games tend to improve cognitive functions more in younger adults than in older adults over the ...
Oct 15, 2021 · Research has shown that playing these types of strategy games can improve cognitive development, such as greater sensitivity to contrasts, better eye-to-hand coordination, and superior memory. Evidence is also present that these types of video games can increase the size and efficiency of brain regions related to visuospatial thinking.
