Langue française - Année 1999 - Volume 121 - Numéro 1 - Pages 56-75Lita LUNDQUIST : Le Factum Textus, fait de grammaire, fait de linguistique ou fit de cognition ? People are able to distinguish with a large degree of consensus between texts and non-texts. In the present article, 1 discuss the theoretical implications of this fact for text linguistics. I demonstrate, partly via a small experiment, that sentences in text can contain three categories of linguistic expressions which contribute to signal their position in the text : anaphors, argumentative signals and mental space builders. Taking a partly psycholinguistic point of view, I argue how text linguistics must integrate cognitive as well as linguistic aspects, but suggest that it can nevertheless obtain status as a linguistic science by satisfying the three criteria proposed by Milner (1995) of falsification, « mathematisation » and « technical application ». 20 pages Source : Persée ; Ministère de la jeunesse, de l’éducation nationale et de la recherche, Direction de l’enseignement supérieur, Sous-direction des bibliothèques et de la documentation.
