La notion de contrastivité dans la mise en mots des représentations sociales.: Remarques méthodologiques sur le bilinguisme en Vallée d’Aoste

As part of a research on social representations of languages, bilingualism and bilingual education carried out by the IRRSAE from Aosta Valley, the writer of this article analyses other contexts suggested by speakers in the Aosta Valley. He tries in the first place to define these speach situations where these associations, comparisions or oppositions to other bilingual realities appear. Finally, on the basis of the works by Perelman & Olbrechts-Tyteca, the author situates them according to the role they play in the argumentation.
