Abstract
-
It has been claimed that a central syntactic processor underlies all modalities of language performance. This claim has been supported by evidence of parallel syntactic deficits in the production and comprehension of language by agrammatic aphasics. These parallels have been demonstrated across groups of subjects, but rarely within groups. The present study applied two dissimilar comprehension tasks to agrammatics (and to fluent aphasics as controls) in order to test the parallel deficit claim. One of these tasks was a paraphrase judgment paradigm using written input; and the other was an auditory comprehension paradigm. It was found that each aphasic group produced deficit patterns that were task-independent (i.e., were parallel across tasks). The deficit patterns produced by the two groups differed. Further analysis indicated that the agrammatics, lacking the use of syntactic cues to grammatical relations in relative sentences, resort to a sentence processing strategy based on the proximity of semantically compatible nouns and verbs, and on canonical word order. While the agrammatic deficit was shown to be task-independent, the use of a strategy or strategies was task-dependent in some subjects.
