"As fun as they may be to play, brain training games have one fundamental flaw: the improvements you see the more you perform the exercises are not evidence of your brain becoming better, smarter, or faster. Instead, the improvements are the same sorts of improvements that you will see in almost any task: the more you practice, the better you get at it. You haven't gotten any smarter, you've just learned how to perform the task at hand faster and more efficiently which translates into a better score.
"An example from one recent brain training game, The Amazing Brain Train, is illustrative of my point. One of the mini-games is called "Pond Sum". In this exercise the idea is to guide a frog across a grid of lily pads laid out on a pond. Each pad is numbered and the idea is to guide the frog in such a way that the sum of all of the numbers that he jumps on will equal the number displayed at the top of the screen."
