Acknowledgments. We wish to express special appreciation to Dr. Margaret Naeser, who kindly undertook a detailed analysis of one of the CT-scans. Dr. W. Burgess assisted in preparing stimulus materials. Patient scheduling and testing was facilitated by the cooperation of D. Frank Benson, M.D., Bruce Gerratt, Ph.D., Bette Hadler, M.A., David Keith, M.A., Daniel Kempler, Ph.D., Jeffrey Metter, M.D., Bruce Miller, M.D., Gail Monahan, M.A., and Adam Wechsler, M.D. This project was supported in part by the Veterans Administration.

N2 - A dissociation between facial recognition and facial discrimination is well known, but investigations of “phonagnosia” (impairment of voice recognition and discrimination) have not been pursued. Using familiar and unfamiliar voices as stimuli, a marked difference between the ability to recognize familiar voice and the ability to discriminate between unfamiliar voices was identified in five patients, and a sixth showed a severe impairment in both tasks. Clinical and radiologic findings in these cases suggest that recognition of familiar voices is impaired by damage to inferior and lateral parietal regions of the right hemisphere, whereas impairment of voice discrimination abilities is associated with temporal lobe damage of either hemisphere. This dissociation of recognition and discrimination of the human voice suggests that these two functions are mediated by different brain structures and may contribute differentially to clinical syndromes.
