Phoneme and timbre monitoring in left and right cerebrovascular accident patients.
Ten left hemisphere and 10 right hemisphere CVA patients were required to monitor for the target phoneme /b/ in a series of monosyllabic words, and a target timbre in a series of eight different timbres. Left hemisphere damaged aphasic patients were more accurate for target timbres over phonemes; the reverse pattern was found in the nonaphasic right hemisphere patients.
