Deep dyslexia and the right-hemisphere hypothesis: What’s left?

Abstract

One account of the residual reading abilities seen in deep dyslexia asserts that they entirely reflect the operation of an intact right-hemisphere reading system rather than a partially disabled left-hemisphere reading system. Evidence from experiments on normal subjects suggests that there is no representation in the right hemisphere for words that denote color that can be accessed by visual presentation. Examination of several deep dyslexic’s color-word reading abilities reveals little deficit. This suggests that the right-hemisphere account of the residual reading abilities seen in deep dyslexia is not a sufficient one. © 1981, The psychonomic Society, Inc.. All rights reserved.
