RELEVANCE OF ADVERB DISTRIBUTION FOR THE ANALYSIS OF SENTENCE REPRESENTATION IN AGRAMMATIC PATIENTS

In this study, it is shown that functional categories are present in agrammatic grammar. Specifically, the verb-adverb order is investigated in three agrammatic patients by means of a constituent ordering task. It is shown that when the verb is in a nonfinite form, it either precedes or follows the specifier-like adverb (both positions are correct), but when the verb is finite, the adverb always follows it (which is the only possible order). The conclusions are that (i) a functional category (namely Inflection), which is responsible for the relative order verb-adverb (of the relevant class), must exist in agrammatic grammar, and (ii) agrammatic aphasia cannot be described as a syntactic impairment involving basic sentence structure. © 1993 Academic Press, Inc.
