Abstract

Abstract In the light of continuing disagreement as to the nature of agrammatisrn in Broca's aphasia, the purpose of the present investigation was to probe further into this syndrome in a case study of a Polish-speaking agrammatic aphasic with left-hemisphere damage of cerebro-vascular origin. The patient's production, comprehension and grammatical judgement abilities were investigated in a variety of tasks. Supplementary information (writing, reading, repeating and naming) was also elicited. Results do not warrant a production versus comprehension dichotomy, but the patient's performances exhibited a clear dissociation between marked syntactic and mild morphological disruptions. Performance patterns across tasks showed that at least some aspects of syntax and semantics were exploited and that normal computational heuristics, as well as compensatory strategies, were applied.
