Summary

Abstract

In this chapter, studies on morpho-syntactic processing of Korean-speaking adults with Broca's aphasia are reviewed. In the production of grammatical morphemes, the aphasic adults could produce certain grammatical morphemes as correctly as normal adult subjects. In the comprehension of simple sentences, as with normal adults, the aphasic adults relied more on case-marker cues than on animacy or word-order cues, although they did not utilize case markers as extensively as normal adults. In comprehending sentences with relative clauses, the aphasic patients' performance patterns varied depending on the severity of their language deficits; while the moderate aphasic patients appeared to rely on word order, the mild aphasic patients showed evidence of their abilities to process case markers. It was also noted that the aphasic adults' sentence comprehension was greatly affected by the processing load of the tasks. The importance of the specificity of languages, the patients' severity of aphasia and the processing load of tasks in research on aphasia are discussed.

Introduction

Individuals who suffer from aphasia experience breakdowns in language processing. The relative degree of impairment across the different aspects of language processing varies between patients. Patients with Broca's aphasia are known to have pronounced deficits in morpho-syntactic processing. Their speech production is often characterized by a marked reduction in phrase length and syntactic complexity with omissions of inflections and grammatical function words, giving the patient's speech a “telegraphic look.” (Goodglass, 1993).
