Abstract

The complexity of a verb’s argument structure influences accuracy of sentence production in aphasia. Here we report preliminary evidence from five participants with aphasia that semantic argument structure and/or syntactic phrase structure contribute to processing difficulty in persons with aphasia in ways that cannot be accounted for as length effects. We contrasted repetition of sentences containing verb particles and prepositional object structures that were balanced for length and lexical content. Results indicated that the verb particles were used correctly significantly more often than the prepositions in sentence repetition.
