 We developed auditory word-picture matching tasks for three semantic category levels and examined the performances on these tasks by patients with aphasia. The subjects were 43 aphasic patients and 10 non-aphasic patients with right hemisphere brain damage. For each of the tasks, six pictures (one target item and five foils), were presented during each trial. In the Level 1 task, all of the foils were semantically different from the target item (e.g. target dog: foils bed, cabbage, etc), while in the Level 3 task, the foils were semantically similar to the target item (dog: cat, pig). The Level 2 task was midway between the Level 1 and 3 tasks (dog: peacock, penguin).

 The number of correct responses in the aphasic group was significantly lower than the non-aphasic group. The number of correct responses was significantly different for each task level in the aphasic group but not in the non-aphasic group. In the subgroups of mild aphasia and aphasia with good auditory comprehension, the number of correct responses to the Level 3 task was significantly lower than the non-aphasic group, but not for the Level 1 or Level 2 tasks. The number of correct responses was significantly correlated with the auditory comprehension subtest scores of Standard Language Test of Aphasia. We think that our tasks are valid for measuring auditory comprehension in patients with aphasia and that the "within category" tasks like the Level 3 task may be useful for detecting mild comprehension disorders of lexical items.
