Prelinguistic sign mixity and flexibility in interaction

Abstract

Based upon a reflection on the social origins of human psychological functions the authors propose an analysis of the transmission-appropriation of object uses by the 7 to 13 month old child through interaction with the adult termed baby-object-adult triadic interaction. The analysis is based on Peirce’s semiotics. Semiotic processes involved in the interaction are analysed with categories of icons, indexes and symbols. The authors show the great variety and flexibility of the signs used by the adult but also by the prelinguistic child. They also evidence different types of sign mixity. Peirce described a sign mixity which implies that the uses of signs is never pure but that a given sign may comprise elements of other signs and thus may belong to different sign classes. Here a second type of mixity is demonstrated which can be specified by the simultaneous occurence of sign configurations or estellas belonging to different semiotic repertoires. These may be implemented by the child or the adult or by both within the interaction.
