My research suggests that video game players have, on average, much higher cognitive abilities than non-players. Experiments done show that players have above average scores in tests such as digit-span forward, divided attention, and spatial recognition abilities.
However, the question still to be answered is do these games increase such abilities or do people with higher cognitive function gravitate towards playing games?
A study of over 500 random participants highlighted that players who class themselves as expert players (and specifically role-play games) scored significantly higher than novice players and non-players. But it must be also concluded that games like Nintendo's brain training, are simply drill and practice for tests as stated above. Hence, as practice makes perfect, players will always score higher and the more expert the player , the higher the score.
So are brain training games increasing the players cognitive ability or just teaching them to pass the test? And does the immersive environment of a compelling Role-Play Game merely motivate the player to fine tune their executive functions or do they also learn meta-cognitive techniques to enhance their learning? Long term studies by doing pre-test and post-test are not really possible as you cannot isolate the player from all other facets in their live that may improve basic cognitive abilities. My past and current experiments conclude that games do accelerate these executive functions within the player, but results can never be conclusive and can only suggest.
Food for thought! What is your opinion, I would be interested in discussing this.
