Stimulus-specific neglect in a deep dyslexic patient.
We report a patient (B.V.) who appears to suffer from two dyslexic disorders. First, B.V. showed a severe impairment in reading aloud nonwords (e.g., reading TREST as TREE), in addition to making several semantic errors when reading aloud words (e.g., reading ILL as SICK) and in picture naming (e.g., responding KNIFE to a picture of a FORK). These results suggest that B.V. suffers from deep dyslexia. Second, B.V. showed an impairment in reading the final letters of both words and nonwords (e.g., reading SHOWN as SHORT and reading PROGE as PROOF). Thus, it appears that B.V. also suffers from neglect dyslexia. We discuss how these two forms of dyslexia could be interacting to account for B.V.'s pattern of errors in reading aloud words and nonwords and in picture naming.
