Recognition reading in paralexia.

Reading aloud and recognition reading were examined in a paralexic patient. Certainty ratings made by the patient during oral reading indicated that he was usually unaware of paralexic errors which he made. In an auditory recognition reading task for words previously misread, the patient still performed poorly, often chosing his paralexic response as the correct alternative. Possible mechanisms underlying paralexia are discussed in the light of these findings.
