Joseph Kable and co-authors at the University of Pennsylvania have publish a study that, not only did commercial brain training with Lumosity™ have no effect on decision-making, it also had no effect on cognitive function beyond practice effects on the training tasks. During the last decade, commercial brain-training programs have risen in popularity, offering people the hope of improving their cognitive abilities through the routine performance of various “brain games” that tap cognitive functions such as memory, attention and cognitive flexibility. Ready the study in Journal of Neuroscience and Penn Today.
