 We investigated sequential changes in the error content of an aphasic patient using auditory word/picture-matching tasks. The subject was a 32-year-old male who developed severe sensory aphasia following a left cerebral hemorrhage. At the initial examination 12 months after the onset of aphasia, he was unable to comprehend even simple words. Unrelated errors were more common than semantically related errors for the target items. The patient was able to comprehend some words at 20 months after onset, when the target items were presented with foils of different semantic categories (e.g., target is "dog" and foils are "cabbage" or "hammer"). The correct answer ratio had significantly improved compared with that recorded at 12 months after onset. However, when the target items were presented with the same-category foils (e.g., target is "dog" and foils are "cat" or "pig"), no significant improvement was noted, although the proportion of unrelated errors had significantly decreased. Then, the patient showed significant improvement at 32 months after onset, even when same-category foils were presented. These results suggest that the error content changes according to the improvement in comprehension deficit.
