Abstract

Agrammatic individuals show impaired production of verbs with complex argument structure. Whether these participants show argument structure deficits during comprehension, however, is unclear. The present study investigated this issue by examining electrophysiological responses to argument structure violations in agrammatic individuals and healthy adults. Results showed that unlike control participants, who evinced a negative effect followed by a positive shift (N400-P600) in response to argument structure violations, individuals with agrammatic aphasia showed a P600 response only. This suggests impaired real time processing of the thematic requirements of verbs.
