Abstract
-
Formulaic and novel language was studied in normal aging and Alzheimer's disease. Two schools of thought regarding formulaic language have arisen in the literature on language in Alzheimer's disease. One hypothesis is that processing formulaic language is more difficult than processing novel (propositional) language. However, descriptive studies indicate that formulaic language production is more abundant than novel language in the speech of those with AD. Four experiments were administered to explore this controversy, as well as normal aging effects. Both types of language were tested with respect to various types of processing using a comprehension task, a grammaticality judgment task, a sentence completion task and a sentence repetition task. Results support a dissociation between comprehension and the other language abilities tested in Alzheimer's disease; comprehension of formulaic language is more compromised by the disease process and production (repetition, grammaticality judgment, and sentence completion) is relatively preserved. In normal aging this dissociation was not seen. Age related decline was noted, however, on those tasks which required complex processing and increased memory load.
