De la valeur sociale des personnes à celle des objets : étude expérimentale de la généralisation de l'utilité et de la désirabilité sociales

Abstract : Following evaluative framework of social judgment (Beauvois and Dubois, 2009), this thesis aims at showing that the two dimensions of persons judgment (the so called : "social utility" and "social desirability") correspond to two evaluative knowledge's modes that can be applied to common objects judgment. More precisely, we propose to demonstrate that these two evaluative modes can be 1. induced from evaluative practices made either into the person register, or into the object register, and 2. then generalized to objects descriptions (following induction into person register) or to persons descriptions (following induction into object register). Two researches started with showing that current and evaluative adjectives that are suitable for objects description are massively structured by two dimensions similar to social desirability and social utility (respectively "agreeableness" and "market value"). Six other experiments intended to test the generalization of the two evaluative modes. As predicted, results showed that it is possible to induce the two evaluative knowledge modes, especially that which pertains to persons social utility and market value, and another descriptive knowledge mode, and that these induced modes can be generalized from persons to objects and conversely from objects to persons. Thus, these findings suggest that the social desirability and the social utility traits dimensions function like two general modes of evaluative knowledge that can be applied to any social object. They also confirm that the mobilization of these two modes is not a consequence of psychological realism, but result of evaluative social practices. Theoretical implications for the evaluative framework as well as directions for future work and a potential application for consumer psychology are discussed.
