Normes sociales de jugement et décisions de groupes

Abstract : The framework of this thesis is located at the same time in the field of research on the decisions of groups and in the field of research of the social norms of judgement. Research on the discussions and group decisions highlighted a scouring phenomenon : the polarization of group, consistent in a toughening of the decision of group towards a prominent and developed side. On the basis of the report according to which the decisions of groups link with the value, we studied the influence at the time of group decision implying of the social norms of judgement. We carried out six experimental studies. The principal results indicate discussion of group implying of the normative proposals: 1) polarization link with the value and more precisely with social utility and less with the social likeableness ; 2) an activation of the social norm takes place. This one consists especially of a stimulation knowledge of the devalorization of no normative propositionals; 3) an effect of generalization will intra and inter norms is observed.
