Agrammatism implies a lack of grammar, but recent studies suggest that agrammatic subjects retain a great deal of grammatical knowledge. This research explored sensitivity to grammatical violations to obtain a clearer picture of the relationship between knowledge and performance in this disorder. This research also investigated the extent to which aspects of morpho-syntactic processing might be differentially disrupted. Agrammatic and control subjects were tested for sensitivity to word order and agreement violations in four experiments: (1) Off-line grammaticality judgment, (2) On-line grammaticality judgment, (3) Repetition of grammatical and ungrammatical sentences, and (4) Repair of ungrammatical sentences.Subjects--Topical Terms:

520 $a Agrammatism implies a lack of grammar, but recent studies suggest that agrammatic subjects retain a great deal of grammatical knowledge. This research explored sensitivity to grammatical violations to obtain a clearer picture of the relationship between knowledge and performance in this disorder. This research also investigated the extent to which aspects of morpho-syntactic processing might be differentially disrupted. Agrammatic and control subjects were tested for sensitivity to word order and agreement violations in four experiments: (1) Off-line grammaticality judgment, (2) On-line grammaticality judgment, (3) Repetition of grammatical and ungrammatical sentences, and (4) Repair of ungrammatical sentences.
520 $a The results of the judgment experiments show that aphasic subjects retained some sensitivity to grammatical violations, though less than control subjects. Also, aphasic subjects were able to use this information on-line as they formulate their decisions. However, they were not equally sensitive to both violation types. Processing of word order violations was less disrupted than agreement violations.
520 $a Aphasic subjects experienced difficulty repeating grammatical and ungrammatical sentences and repairing ungrammatical sentences. However, they demonstrated similar (although degraded) performance patterns relative to the control subjects. During repetition, aphasic subjects experienced more difficulty with ungrammatical sentences and their errors were often in the direction of inadvertent correction, indicating grammatical sensitivity. Aphasic subjects made attempts to correct the grammaticality of the sentences during the repair experiment. Although performance was impaired compared to the control subjects, their attempts reflected some sensitivity to the violations as revealed by corrections involving the violation included in the target sentence. However, as in the grammaticality judgment tasks, greater sensitivity and productive control over word order violations was observed relative to violations of agreement.
520 $a The results of these experiments suggest that agrammatic asphasic subjects retain some linguistic knowledge, but their processing of this knowledge is disrupted. However, certain aspects of morpho-syntactic processing are differentially impaired as revealed in greater sensitivity to word order than to agreement violations. The findings are consistent with a view of language processing involving cue convergence over a context-sensitive lexicon and a view of agrammatic aphasia as disturbance to that processing.
