«The vast majority of our youth play video games for more than three hours a week, but the beneficial effects on decision-making and the brain are not exactly known,» said lead researcher Mukesh Dhamala, assistant professor at the Georgia Department of State. Physics and Astronomy and the University's Institute of Neurology on gbwhatsapp.
«Our results show that frequent video game players are better at tasks that require sensorimotor processing and cognitive decision making, which can help our military personnel on the battlefield.»
During the study, the researchers administered a series of tests to the participants to assess their visual attention, sensorimotor processing, and cognitive decision-making skills. They found that avid video game players were better at these tasks than non-gamers. Those who played about three hours a week had an advantage over those who did not play games in performing both visual attention and sensorimotor tasks. In addition, those who frequently gamble had higher activation in areas of the brain associated with visual attention and sensorimotor processing compared to those who did not.
Avid gamers also showed significantly more activation in brain regions associated with cognitive decision making compared to non-gamers, including areas for integrating information from multiple senses, planning ahead, and suppressing inappropriate responses.
«Our results suggest that frequent video game play may be associated with specific neural adaptations that maintain cognitive control in healthy adults,» the authors write.
«These neural differences may be important in understanding the potential health risks associated with video games, especially for adolescents and children, where the benefits of cognitive control are particularly important.»
The study «Neural Correlates of Video Games in Adolescents and Adults» was published in the June issue of the journal PLOS One.
Jordan, who received his doctorate in physics and astronomy from the State of Georgia in 2021, had poor vision in one eye as a child. As part of the study, when he was about 5 years old, he was asked to cover his good eye and play video games to improve the vision of a weak one. Jordan credits video game training with helping him go from legal blindness in one eye to developing strong imaging abilities that eventually allowed him to play lacrosse and paintball. He is now a doctoral student at the University of California, Los Angeles.
