Dyslexia and specifically distorted drawings of the face - a new subgroup with prosopagnosia-like signs.

Identification of a subgroup (38%) of dyslexics (new syndrome?). These, against controls (5.5%), drew 'neolithic' face configurations analogous to those visually experienced in prosop-agnosia. Essential symptoms of this subgroup are seen as result of specific early ways of processing visual data: lexical shapes (letters, words) and facial features, as if these were concrete entities, not abstract component parts. Thus, with letters, taken as entities, d = q, d = b, N = Z.
