Abstract
|
|
|
The purpose of this study was to compare receptive language performance and expressive language perormance in 13 patients with aphasia by using three stimulus presentation modes´ Stimulus mode I (picture), Stimulus mode II (written word), Stimulus III (question using verbal explanation). The stimulus consisted of 10 words. They included 5 functional word and 5 non-functional words. The 13 subjects with aphasia were divided into 2 aphasic types: 5Broca´s aphasics and 8 anomic aphasics. The results were as follows:
Firstly the three stimulus modes didn´t affect recptive language performance of aphasia subject. Secondly, the three stimulus modes were effective on expressive language performance of aphasia subjects. Particularly, stimulus mode II (written words) was effectivein naming the aphasia subjects. Thirdly, the functional words with high frequency were better than non-functional words with low frequency on expressive language performance, but not on receptive language performance of aphasia subjects. Finally, the interaction between three stimulus modes and the functional (nonfunctional) words effected expressive language performance only, but not receptive language per:ormance. Particularly, presenting stimulus in written words which are functional words produced the best expressive language performance.
