Two years ago we published a Cerebrum article, “The Brain Games Conundrum: Does Cognitive Training Really Sharpen the Mind?” Complicating the issue for our co-authors, Walter R. Boot and Arthur F. Kramer—both neuroscientists who had spent years studying cognitive psychology, neuroscience, and aging—were two open letters to the neuroscience community from more than one-hundred scientists, one objecting to effectiveness claims made by brain-game companies and the other a rebuttal saying brain training has a solid scientific base.
Near the end of a Q&A with Boot and Kramer following the article’s publication, Boot predicted that “maybe in ten years we might know enough to make more definitive recommendations.”
Boot’s prediction was reaffirmed earlier this week with the publishing of a comprehensive evaluation of the scientific literature on brain games in the journal Psychological Science in the Public Interest. Seven scientists, including Boot, reviewed more than 130 studies of brain games and other forms of cognitive training. The evaluation included studies of products from industry giant Lumosity.
