Abstract

Both young children and agrammatic aphasic speakers have difficulty interpreting pronouns, but not reflexive elements. This phenomenon is known as the delay of Principle B effect in language acquisition. The interpretation of pronouns is non-adult-like for children and disturbed in agrammatic aphasia, yet there is evidence that interpretation of pronouns is not always problematic for these populations and that it seems to be governed by linguistic principles. This chapter examines the linguistic principles underlying the interpretation of pronouns and reflexives among children and agrammatic aphasic speakers whose native languages were Dutch, Spanish, and Italian by focusing on two types of sentences: simple transitive sentences and Exceptional Case Marking constructions. It first looks at earlier research on language acquisition and agrammatism before discussing two important linguistic theories, Government and Binding Theory and Reflexivity and Primitives of Binding.
