Variabilité inter-individuelle, contrainte de l'environnement et structuration de groupe : une étude chez le rat Wistar

Abstract : The present work concerns a social differentiation that systematically appears in small groups of rats placed in a situation of alimentary constraint. The first part is devoted to the detailed typology of the individuals. Two types are characterized: some rats are able to overcome the constraint. The others cannot act in such a waif and must attack the formers in order to steal the food. The second part concerns the socio-cognitive process in the groups; in terms of specialize and interdependent roles which do not correspond to a dominance hierarchy. The last part is devoted to the ontogenesis social differentiation determinism. The results from a set of tests applied to the rats between birth and adult stage can predict the future of roles of the rats in the experimental situation.
