The desire to improve our cognitive ability through brain-training games has turned into what is said to be a trillion-dollar industry. Such games are based on the idea that testing our memory, attention and other types of brain processing will improve our overall intelligence and brain function. Companies like Lumosity, Cogmed and Nintendo are all cashing in hugely on this idea. But many scientists and experts in brain research feel the theory has serious flaws. There has yet to be concrete evidence proving anything close to what such companies claim to be able to do.
In fact, David Z. Hambrick, associate professor of psychology at Michigan State University, and his colleagues Tom Redick (lead researcher) and Randy Engle will soon be publishing new evidence that fails to replicate the very study that so much of the commercial industry rests upon. SmartPlanet spoke with Hambrick about the limits of intelligence and the findings from this new and potentially ground-breaking study.
