HJF Researcher's Brain Training Featured by NPR
'Dual n-back' training, one of two brain-training methods most scientists use in research significantly improves memory and attention better than the other method and shows more significant changes in the brain, reports NPR.org.
Led by Kara Blacker, a former postdoctoral fellow in psychology and brain sciences at Johns Hopkins University and current researcher at HJF, the study showed that the kind of brain training people use matters. The exercises did not make anyone smarter, but they did improve skills needed to excel at school and at work.
Three groups of participants were given tests for baselines in working memory, attention and intelligence. They also had EEGs to measure brain activity. Groups trained on different brain exercises not commericially sold, but tools scientists rely on. Those who practices the 'dual n-back' exercise showed a 30 percent improvement in working memory, nearly double the gains made by the group working with the other common method.
