Today’s NY Times reports on a planned study of the effectiveness of Posit Science’s Brain Fitness Program on veterans who suffered traumatic brain injuries (TBI) in combat. Posit Science was founded by Dr. Michael Merzenich, whose research into neuroplasticity forms the basis for the Fast ForWord programs.
Dr. Merzenich’s core claim is that brain structure is always changing, based on what people do and what they pay attention to. By doing specific brain exercises that focus and refine attention, he says, you can adjust the underlying structure of your brain. It is well established that this happens when we learn a new skill, like dancing. The question is, Can the same processes be employed to correct for brain damage?
Psychologists and others observing the study range from the cautiously optimistic (quoted in the Times, Gary Abrams, director of neurorehabilitation at U.C.S.F. and head of the T.B.I. support clinic at the San Francisco VA Medical Center, says “It is theoretically reasonable, but will it actually work to help veterans?”) to the skeptical (also cited, in the Times, Dr. P. Murali Doraiswamy, a Duke University psychiatrist, is “not convinced that gains translate into long-term benefits that can be generalized to daily challenges like remembering where the car is parked”).
The study will involve 132 veterans suffering from TBI. They’ll undergo a battery of cognitive tests before the program, and again 3 and 6 months after the program.
The Times article also makes a critical point that we frequently make about the neuroplasticity-based programs (Fast ForWord and Cogmed) that we use with struggling learners: the programs are different because they address the underlying cognitive deficits, rather than compensatory strategies.
