A phoneme discrimination test, based on CCVC (Consonant-Consonant-Vowel-Consonant) syllabes was administered to 42 controls, 43 right brain-damaged patints, 48 non aphasic left brain-damaged patients and 36 aphasic left brain damaged patients, under normal listening conditions. An overall evaluation of the test, aphasic patients were significantly more impaired than both controls and other brain-damaged patients. Errors made in the discrimination of phonemes contrasting in voicing or in place of articulation were then considered. Aphasics were once more clearly distinguishable from the other subjects, since they showed a relatively greater difficulty in discriminating place rather than voice contrasts. Some implications of these findings are discussed.
