[Strategies of interpersonal negotiation in children 18-24 months of age (conflict, avoidance and resolution of the conflict)].

This research seeks to determine the social competence of children between 18 and 24 months of age. It took place in two consultation centers (PMI) (50 children of North African origin) and two nurseries (20 native children). Each child is observed in a "natural" setting: in a waiting room and during free activity. The sequences in its behavior allow us to pinpoint the conflicts arising between the child and its peers as to who gets what and how an object is used: it also allows us to analyze the negotiating tactics it brings into play: resolution or avoidance tactics. Three conclusions can be drawn: 1. The ways of negotiating depend on the context; 2. The young child's negotiating shows processes of becoming less self-centered that go from mere anticipation to coordinating viewpoints; 3. Each child shows an interactive style. This research could contribute to creating a preventive policy: the pedagogy of conflict and a program for learning to interrelate socially.
