This is news that many have long awaited. Researchers can now say conclusively that playing action videogames can have a positive effect on the brain.
Canadian psychologists from the University of Torontohave revealed that playing action video games, even for a relatively short time, cause differences in brain activity and improvements in visual attention.
This is the first time that research has been able to attribute the brain activity differences directly to playing video games, not to preexisting differences in the brain.
Not sure how the researchers did this, but they managed to find 25 people who had never played a video game, and they had them play for 10 hours broken down into one and two hour segments. Sixteen played a shooting game and nine played a three-dimensional puzzle.
Before and after the games, the subjects’ brain waves were recorded while they completed a task—detecting a target among other distractions in a wide visual field.
