In order to under stand a sentence, it is necessary to under stand every word which make up the sentence and to under stand how they function in the sentence structure. This study attempted to investigate the specific features that Broca, Wernicke and anomic aphasics show in their under standing of a sentence structure. The material used for the research was a syntactically ambiguous sentence. An example is 정치가 which is ambiguou s between the two meanings of 정치(politics ) + 가(particle) and 정치가(politician ). Reading time for resolving ambiguity in a self- paced reading task was measured. In the previous research for normals, there was no difference between ambiguou s/ unambiguou s sentence when a sentence segment like 정치가 was used as a subject , meaning politics + particle, but a significant difference was found when the sentence segment was analy sed as noun + affix , meaning a politician. T herefore we concluded that Koreans analyze an ambiguous segment like 정치가 as a subject ( politician + particle ). It was also found that three patient subject s had no diffuculty in proces sing morpho- syntactic information campared with the normal subject s. However , all of the aphasic subject s took longer time than the normal subject s to read the sentence. Furthermore, in the case of Wernicke aphasic, she did not have difficulty in the proces sing of morpho- syntactic information, but had obviou s difficulty in integrating information of the last segment of the sentence.
