Zitat des Tages von Daphne Bavelier:
Studies of social games, puzzle games, and brain-training games have shown they have little effect on the brain despite often being marketed as improving memory and reaction speeds.
Action game players make more correct decisions per unit time. If you are a surgeon or you are in the middle of a battlefield, that can make all the difference.
When people play action games, they're changing the brain's pathway responsible for visual processing. These games push the human visual system to the limits, and the brain adapts to it.
'Screen time' is meaningless - what matters is what you do while on the screen. The good, the bad, and the ugly faces of screen time will all have to do with which activities you engage into.
We need to go beyond saying, 'I know what these games do because I see my son playing them,' and try to understand the complexities - that different video games have different effects.
Normally, improving contrast sensitivity means using glasses or surgery to correct the eye. But we've found that action video games train the brain to process visual information more efficiently and improve vision.
In order to sharpen its prediction skills, our brains constantly build models, or 'templates,' of the world. The better the template, the better the performance. And now we know playing action video game actually fosters better templates.
Everybody thought that screen time was bad for vision. Well, it happens that spending a lot of time reading on a computer is bad for your vision, but spending a lot of time playing first-person-shooter games is good for your vision.
People who played action video games have better vision in the sort of conditions where there is not much contrast. It can make all the difference when driving at dusk, or in fog, in being able, for instance, to see a dog crossing the road in twilight.
