Sharp Brains: Brain Fitness and Cognitive Health News

Neuroplasticity, Brain Fitness and Cognitive Health News

Icon on Brain Fitness: Tree or Forest? published yesterday a thought-provoking article focused on Posit Science’s Brain Fitness Program, titled Buff Up Your Brain, that combined a) some pretty good analysis and great points about that specific program and justifiable (to a point) criticism of the commercial tone of a recent PBS Special, with b) the error of confusing a tree with the forest, that led the author to make several unwarranted claims regarding the field.

Computerized cognitive training has been around since way before Posit Science, and will be here way beyond Posit Science (and SharpBrains, and, and their auditory processing product-featured in the PBS Special- is not, in our view, the most particularly impressive example. Well-directed cognitive exercise can enhance mental skills and transfer to real-life outcomes, acting as a good complementary tool, when used properly, to other lifestyle options and tools.

For example, we read that “At present, the only way a brain fitness program can demonstrate its value is through traditional “neuropsychological testing.”” and that “But it isn’t easy to create a double-blind study for a computerized brain exercise program.”

I suspect the author is not familiar with Dr. Torkel Klingberg’s work, for one, summarized in this list of scientific papers:,

or many of the others mentioned in the End Notes of our recent report, such as

Or the ones we review in more detail, from researchers such as John Gabrieli and Karlene Ball.

So, please, let’s clarify: are we talking about a tree, or perhaps even several trees, or the forest?

And, when talking about one specific tree, can we please clearly state what tacit hypothesis is being refuted: whether it is  a “general solution” or not (in our view, no program is) or a specific tool, that, like any tool, can be useful in the proper context?

And now, good night!-as we saw recently, sleep is a much needed, inexpensive yet time-consuming, brain fitness program

    After two TIA strokes my brain is limited. If I hear someone go into a complicated discus-sion, my brain will shut down. Memory of even important dates are elusive. This is since my last stroke. I had to wait 12 hours for treatment in the emergency room–after both strokes! The hospital had no rooms available, so no one would even look at me until I was admitted.
    My long-term memory works pretty well. I can remember names of movie people from 50 or more years ago.

    Hello Bill, thanks for sharing your experience. May stroke survivors get better after periods of rehabilitation, both physical and cognitive. Your neuropsychologist and speech therapist should be able to work with you and help improve, as much as possible, areas such as information processing and working memory.

    Kind regards
