Possible role of abnormal auditory feedback in conduction aphasia

A 63-yr-old man with conduction aphasia was asked to repeat 4 monosyllables, 1 polysyllable, and a sentence under normal conditions and under Delayed Auditory Feedback (DAF). In 20 normal controls, DAF produced louder and slower speech and linguistic errors similar to those found in mild expressive...

Description
Summary:A 63-yr-old man with conduction aphasia was asked to repeat 4 monosyllables, 1 polysyllable, and a sentence under normal conditions and under Delayed Auditory Feedback (DAF). In 20 normal controls, DAF produced louder and slower speech and linguistic errors similar to those found in mild expressive aphasia. In contrast, the patient with conduction aphasia showed little increase in intensity and spoke faster and with fewer linguistic errors under DAF than under normal conditions. The paradoxical improvement inducedby DAF in this patient suggests that abnormal auditory feedback may cause some of the features of conduction aphasia.
