[The demonstration of communication behaviors in children with early psychoses].
The authors present a research project on the ways children suffering from early psychosis communicate non-verbally. These children are studied in their regular treatment center, using a behavioral method using a set of possibilities described for a normal young child. For the three children who were studied, rather different means of non-verbal communication were highlighted, which changed and were enriched when the adult taking care of them "improved" the way his interaction with the child was organized. Our findings raise questions concerning the semiology of these conditions and it's treatment.
