A study of about 2,000 children Scientists from the University of Vermont, USA, and published by JAMA Network Open, contradict the maxim that “video games are bad”. According to the report, children who reported playing video games three hours or more per day performed better on tests of cognitive abilities than those who never played.
The study tested 9- to 10-year-olds, dividing them into groups of those who played or didn’t rate. Their performance on two tasks that measured the ability to control impulsive behavior and remember information. The children’s brain activity while performing the tasks was also analyzed.
“This study adds to our growing understanding of the associations between video game play and brain development,” said Nora Volkow, director of the National Institute on Drug Abuse, which provided most of the data analyzed. “It also suggests that there may be cognitive benefits associated with this popular pastime, which warrants further investigation.”
During the study, functional analysis of MRI brain images showed that children who played games showed increased brain activity in brain regions associated with attention and memory. At the same time, there is less brain activity in brain regions related to vision. The researchers believe that this relatively low activity is due to visual processing as a result of playing the games repeatedly.
Although previous studies have shown an association between video games and increased depression, aggression, and ArrhythmiasThis was not the case with the new work. However, the researchers emphasize that this study does not allow for a cause-and-effect analysis, and therefore does not mean that children should spend unlimited time on computers, mobile phones or televisions, in addition to video games themselves..
