Researchers from Georgia State University found out that video game players show better decision-making skills and enhanced activity in key regions of the brain as compared to non-players.
The authors used functional magnetic resonance imaging (FMRI) and concluded that video games could be a useful tool for training in perceptual decision-making. The subjects lay inside an FMRI machine with a mirror that allowed them to see a cue immediately followed by a display of moving dots. Participants were asked to press a button in their right or left hand to indicate the direction the dots were moving or resist pressing either button if there was no directional movement.
The study showed that video game players were faster and more accurate with their responses. Analysis of the brain scans found that the differences were correlated with enhanced activity in certain parts of the brain.
"These results indicate that video game playing potentially enhances several of the subprocesses for sensation, perception and mapping to action to improve decision-making skills," the authors wrote. "These findings begin to illuminate how video game playing alters the brain in order to improve task performance and their potential implications for increasing task-specific activity."
The study also states that the video game players were better in both speed and accuracy of response.
