Five boys, aged 7.5–10.7 years, presented with a syndrome of severe dyslexia and color-naming difficulty, without comparable object or picturenaming difficulty, without color blindness, and without conspicuous “soft” neurological signs. Their color-naming defect was compared to a variety of color anomias reported in adults with acquired lesions and it was concluded that these boys most closely resemble the “aphasic”, rather than the “disconnexion” type. The remarkable severity and purity of their dyslexia, coupled with the color-naming defect, suggests that a highly specific differentiation of function exists within the cerebral language areas and discrete malfunction can account for specific subtypes of dyslexia.
