The Breakdown of Morphology in Aphasia

The purpose of this chapter is to characterize the breakdown of morphology in the performance of aphasic subjects in sentence and in single-word processing. Evidence from an array of languages investigated within a unilingual or cross-linguistic approach is presented and several recent interpretations are reviewed. It will be argued that the introduction of theoretical linguistic and psycholinguistic considerations into the study of aphasia contributes to a better understanding of the way in which pathology affects the morphological component of language.
