Time course of grammatical encoding in agrammatism. In Clinical Aphasiology Conference: Clinical Aphasiology Conference (2011 : 41st : Fort Lauderdale, FL : May 31-June 4, 2011) / : (2011).
Two on-line sentence production experiments explored the time course of grammatical encoding in normal and agrammatic speakers. Incremental models suggest grammatical encoding proceeds in a word-by-word manner, without advanced planning. Structural models suggest a hierarchical predicate structure (e.g., verb argument structure, VAS) is encoded prior to speech onset. Results showed that when agrammatic speakers produced sentences in a pre-defined order, they produced sentences incrementally, similar to controls. However, in a free sentence production task, both controls and agrammatic speakers encoded VAS prior to speech onset. Further, agrammatic speakers’ syntactic deficits resulted in a greater use of VAS than controls.
