Dichotic listening in psychiatric patients with and without diffuse brain damage.
A dichotic listening test was administered to a group of 49 psychiatric patients with mild diffuse brain damage and a group of 89 without. Despite the lack of difference between the groups on Verbal IQ, the performance of the brain-damaged group was significantly inferior to that of the non-brain-damaged group on a number of measures of error. The most striking difference between groups occurred on the report of digits presented to the left ear, where this report was made subsequent to the report of digits to the right ear. The finding was discussed with regard to its relevance to theories of hemisphetic asymmetry of language functioning.
