New Studies Show Promise for Brain Training in Improving Fluid Intelligence
Whether computerized games designed by psychologists and neuroscientists can literally make people smarter has been hotly debated by scientists, with a small but outspoken cadre of skeptics demanding stronger proof. Now two new studies have found the kind of real-world benefits from the brain-training games that skeptics have been calling for.
The first, published today in the Proceedings of the National Academy of Sciences, found that less than six hours of brain games played over the course of 10 weeks enabled poor first-graders who attend school irregularly due to family problems to catch up with their regularly-attending peers in math and language grades.
The second, presented over the weekend at the Cognitive Neuroscience Society meeting in Boston, combined the results of 13 previous studies of computerized brain-training in young adults to conclude that training significantly enhances fluid intelligence—the fundamental human ability to detect patterns, reason, and learn. That is, practicing the games literally makes people smarter.
Together with other recent studies demonstrating real-world benefits of brain training in healthy older adults, preschoolers, and school children with ADHD, the new papers appear to provide fresh ammunition to psychologists and neuroscientists whose research has been under attack by a handful of skeptics who insist that the training is a waste of time.
