Daphne Bavelier studies how the brain adapts to changes in experience, either by nature or by training
Fears over children playing video games is leveraged by the media for many headlines. While most children play games, most gamers are adults. Daphne is a brain scientist, so has studied the impact of video games on the brain. She notes that excessive gaming is hazardous to the health, but in reasonable levels is generally beneficial. With the amount of time people can play games, she is looking at ways to leverage this power to solve health problems.
Her main focus for these studies were violent first person shooter action games – such as Call of Duty, which in previous tests showed much greater benefits than other games. Her findings were
- Gamers have better vision. This is counter to the old story that too much screen time will harm your eyes – gamers could make out small details better and could distinguish between shades of grey (useful for driving in foggy conditions). Games are now being developed to improve patients with poor vision.
- Gamers are better at focussing their attention. Again this is counter to the myths, but gamers can track more objects at a time and focus on tests for longer.
- Gamers are better multi-taskers: they can switch from one task to another with minimal cost. They performed better in the multitasking tests than ‘multimedia taskers’ – students who report chatting while listening to music and studying.
Most of these findings fly in the face of common wisdom, and show that scientific testing is necessary to test common knowledge.
Daphne used this to try and improve the brains of non-gamers. She assigned them to play first person shooters for 10hrs over 2wks and tested their ability to mentally rotate shapes before and after. They showed a significant improvement after gaming, and maintained that improvement 5 months after the study.
She is now working with game publishers to better integrate the elements of games that improve our brains while still keeping the games fun. This is not an easy or quick thing to do – since people are wary of past efforts at educational software.
I must admit I am skeptical of some of the studies shown. During the shape rotation one for example she didn’t mention a control group – is it possible the brain is improving as it gets exposed to the same test multiple times? I had a look through her publications (http://cms.unige.ch/fapse/people/bavelier/publications/publication-video-games/) and couldn’t pick out the exact study she was referring to. I hope I am wrong though – it is an interesting result if it is correct.
I am curious about how her work with the gaming companies will end up. If shooting games are already showing these benefits, is she aiming to tweak the games to focus more on the most beneficial points? Or is she trying to build more of these elements into non-shooter games?
Regardless, love the talk. Gaming often gets a bad rap from the media and other old wives tales (of the sort she debunked). It is good to know this is just another round of fear that strikes every generation as the world changes.
