Averaged Encephalic Response of Aphasics to Linguistic and Nonlinguistic Auditory Stimuli

Pamela J. Metting

This study investigated the averaged encephalic responses (AER) of aphasics to words and to white noise stimuli matched to the amplitude of each word. Subjects were classified according to the Functional Communication Profile. Fifty presentations of each of the stimuli were presented to the right and left ears of aphasics while they were completing a simple recognition task. Electroencephalographic (EEG) activity was recorded from bipolar electrodes at right and left hemisphere placements (T₅-F₃; T₆-F₄). Differences were found in the component latencies between hemispheres, but further analysis showed that this was present only in those subjects who had severe communication difficulties. There were no significant AER differences between the stimuli, but the AERs obtained were inconsistent. The differences found could be a reflection of the damage to the left hemisphere which is outwardly affecting the aphasic's communicative behavior.
