![]() What has not been proven is that this translates to improved life skills that involve intelligence and informed decision making. So there is certainly good data that shows that if one engages in learning one particular exercise, performance in that particular exercise does improve. What they will do is improve the performance on the particular test that one trains with. In fact, the most recent data that examine all the studies concludes there is virtually no or very little evidence that the brain games or training improve overall intelligence, memory, or other higher cognitive functions. Subsequent studies have not duplicated the remarkable first report that got the entire concept launched. ![]() The idea gained national recognition in 2008 when Jaeggi published a scientific article that showed with specific cognitive exercises that there was a significant increase in subjects’ IQ. There has been some scientific study and a lot more rhetoric about this controversial topic. The training is to be distinguished from real games like crossword puzzles and Sudoku, which are games with no specific neuroscience target. The fundamental idea is that the exercises that are called games by some will improve performance of the individual in the areas that they target. It has been estimated that the entire industry in 2014 collected $1.3 billion. The Lumosity app was downloaded 50 thousand times a day in January. According to Elizabeth Day writing in The Guardian , Lumosity had revenue of $24 million in January of 2014. Nevertheless, a large number of people do the brain training. And the biologic evidence for the enhancement of critical functions by “exercises” is absent. This works in the gym for the biceps, but the brain is a mushy organ full of neurons, receptors, and proteins that all have specific function. ![]() Skeptics have pointed out that the concept of training the brain is not like training for a marathon, since the brain is not a muscle that gets larger and stronger with repetitive exercises.
