If you are going to read Tallal's 'stuff' you might also want to
check out Michael Studdert-Kennedy as he has some (IMHO correct)
apprehensions about her interpretation of her findings. This is
particularly relevant because there is a 'remedial training technique'
being touted as the next best thing for all sorts of language/phonological
impairments, not just dyslexia. BTW, much of Tallal's application of her
findings to 'dyslexic' children suffers from her lack of a clear, consistent
operational definition of dyslexia. I do think her findings are intriguing,
I am just a bit wary about the whole FastForward (tm) phenomenon and the
way it is marketed as the best intervention for a multitude of language/
phonological problems. My .02 cents. I've assumed you have alluded to
FastForward below:
