Not a week goes by when an article extolling the evils of video games is published, so it’s refreshing to see a positive piece appear. In an interesting bit of research, scientists have determined that people who play action-based video games, like first-person shooters, are 58% better at perceiving fine contrast differences in real life, such as shades of grey.
From LiveScience:
“If you are driving at dusk with light fog it could make the difference between seeing the car in front of you or not seeing it,” study leader Daphne Bavelier told LiveScience.
The ability to discern slight differences in shades of gray, or contrast sensitivity, is the primary limiting factor in how well one sees, said Bavelier, a professor of brain and cognitive sciences at the University of Rochester.
“Normally, improving contrast sensitivity means getting glasses or eye surgery—somehow changing the optics of the eye,” she said. “But we’ve found that action video games train the brain to process the existing visual information more efficiently, and the improvements last for months after game play stopped.”
How was the research conducted?
In the new study, her team tested the contrast sensitivity function of 22 students, then divided them into two groups: One group played the action video games “Unreal Tournament 2004″ and “Call of Duty 2.” The other played “The Sims 2,” which is richly visual, but does not require as much visual-motor coordination.
The volunteers each played 50 hours during the 9-week test. Then their vision was tested again.
Those who played the action games showed an average 43 percent improvement in their ability to discern close shades of gray — close to the difference Bavelier had previously observed between game players and non-game players — whereas the Sims players showed no improvement.
