Abstract

Individuals with Broca’s aphasia show lexical processing deficits, such as deficits in lexical access or lexical integration. Although studies have implicated lexical processing as areas of impairment in Broca’s aphasia, few studies have looked at the effects of these deficits on sentence comprehension. We conducted a series of eyetracking experiments to test whether Broca’s aphasic individuals are impaired in lexical access or lexical integration and whether such deficits affect sentence comprehension. Results showed that while lexical access and lexical integration are both impaired in Broca’s aphasia, only the deficit in lexical integration affects sentence comprehension.
