A microgenetic model of paragrammatisms produced by a schizophrenic speaker.
A series of papers appearing in Brain and Language ask whether schizophrenic language irregularities can be understood in linguistic terms. This literature is reviewed and the contrary positions of different authors are highlighted. The clinical presentation of a schizophrenic male is described. In a single interview he produced a set of paragrammatical errors which are noteworthy insofar as they indicate sustained epochs of diminished expressivity. In this sense, they differ from schizophasic deviance, which is described by Lecours and Vanier-Clement (Brain and Language, 3, 516-565, 1976) as an enhanced expressivity cooccurring with intact language competence. They are also partially decodable, which distinguishes them from the schizophrenic segments discussed by Chaika. Analyses of the paragrammatisms indicate disruptions at three discrete representational levels. One involves the formation of abstract speaker intentions, while the second organizes syntagms into some serial form, and the third level takes content words belonging to a particular syntagm and positions them in a syntactic frame. A microgenic model of these representational planes is proposed that is based on the theoretical perspective of Brown, as well as Garrett's investigations of normal speech errors. The model is justified insofar as the paragrammatisms indicate "linguistic regressions" back to more "thought-like" linguistic representations. Moreover, a recapitulation of specific linguistic mappings is demonstrated to occur between processing levels. This microgenetic model represents an extension of previous work in aphasiology insofar as it targets combinatorial rather than selectional processes as primary planes of disruption.
