Sign of the times
The work is published in Current Biology. What was particularly interesting was that the faster reaction times of the video gamers could be acquired by non-video gamers in 50 hours of training over a few weeks. But for the benefits to accrue, they had to play a particular sort of game.
Only those who played fast-moving action video games such as "Call of Duty 2" and "Unreal Tournament" saw an improvement in their decision-making skills. Rather ironically, players of "The Sims 2", a game where one has to decide how to organise an entire simulated world, did not benefit this way. Those trained with action video-games were 25% faster at coming to a conclusion, and answered just as many questions correctly.
