Controversy about the visual magnocellular deficit in developmental dyslexics

J Stein, J Talcott, V Walsh - Trends in cognitive sciences, 2000 - cell.com
In a recent review, Bernt Skottun1 strongly attacked the hypothesis that some dyslexics show
impaired development of the magnocellular pathway of their visual systems. Significantly …

The magnocellular theory of developmental dyslexia

The current status of the magnocellular theory of developmental dyslexia

J Stein - Neuropsychologia, 2019 - Elsevier
