Conflicting Data About Dyslexia's Cause

摘要

J. D. E. Gabrieli ("Dyslexia: A New Synergy between education and cognitive neuro-science," Review, 17 July, p. 280) mentions that dyslexia could be the result of a deficit in the magnocellular part of the visual system. He cites only a few corroborating studies and provides no counterexamples. In doing so, he risks leaving the reader with the impression that the support for a magnocellular deficit in dyslexia is solid.
