Video Games Shown to Improve Children's Cognitive, Memory Skills in New US Study
Parents often worry about the harmful impacts of video games on their children, from mental health and social problems to missing out on exercise.

Lead author Bader Chaarani, an assistant professor of psychiatry at the University of Vermont, told AFP he was naturally drawn to the topic as a keen gamer himself with expertise in neuroimagery.
Prior research had focused on detrimental effects, linking gaming with depression and increased aggression.
These studies were however limited by their relatively small number of participants, particularly those involving brain imaging, said Charaani.
For the new research, Chaarani and colleagues analyzed data from the large and ongoing Adolescent Brain Cognitive Development (ABCD) Study, which is funded by the National Institutes of Health.
They looked at survey answers, cognitive test results, and brain images from around 2,000 nine- and ten-year-olds, who were separated into two groups: those who never played games, and those who played for three hours or more a day.
This threshold was chosen as it exceeds the American Academy of Pediatrics screen time guidelines of one or two hours of video games for older children.
Impulses and memory
Each group was assessed in two tasks.
The first involved seeing arrows pointing left or right, with the children asked to press left or right as fast as they could.
They were also told to not press anything if they saw a "stop" signal, to measure how well they could control their impulses.
In the second task, they were shown people's faces, and then asked if a subsequent picture shown later on matched
