Outline of Final Research Achievements

In order to obtain suggestions concerning rehabilitation of language comprehension in various types of communication disorders including aphasia, we investigated (1) sound perceptions in Broca's area, (2) relations between auditory processing disorders (APD) and other cognitive dysfunctions, and (3) effectiveness of visual information of mouth movements on phonological recognition in persons with aphasia and non-handicapped persons.
Our results were as follows. (1) We did not find specific characteristics in a person with damage to Broca's area in our experiments. (2) We found a relation of APD to low cerebral blood flow as well as mild memory disorders. (3) We also found visual information facilitated phonological recognition in both persons with aphasia and non-handicapped persons.
