La rationalité de l'incohérence en conversation schizophrène (Analyse pragmatique conversationnelle et sémantique formelle)

We base on well known researches in pragmatics, linguistics and psychology of communication who define the schizophrenics troubles of thought according to their intrication with some properties of language, discourse and conversation. But we observe that those researches fail to represent the cognitive rationality of incoherence. We prepare a new method of analysis which takes the dynamical properties of verbal interaction sequences into account that constitute the natural context of the trouble's expression. This method connects a discourse representation theory (DRT) to aspects of pragmatics and conversational analysis. In the way we make such a model suitable to discontinuity in verbal interaction, we show it is possible 1) to describe the specific processes of thought of the schizophrenic speaker and “normal” and 2) to decipher the dialogical mechanism, probably in part archaic, which maintains the exchange despite disturbances.
