Montre-moi comment tu bouges, je te dirai à quoi tu penses : vers une approche incarnée de la cognition sociale

Abstract : This thesis assumes a grounded approach to social cognition, which defends that our abilities to understand others’ mental states rely on our immediate experience of sensori-motor informations in social interactions and do not need any inference processes. Some critical theorethical limits have been addressed to this approach to social cognition. Typically, it is considered that this conception can not explain high order mentalization, as, for example, the inference of social intentions, because there are not systematic links between those cognitive constructs and the systems of perception and action. Through the studies of this thesis, we have in a first time showed that the kinematics of voluntary movements are influenced by the type of social intention that is endorsed by participants. Precisely, when an action is produced for a partner, its spatio-temporal characteristics are amplified. Then, we have demonstrated that these kinematic variations are influenced by the physical properties of the partner, and particularly by the eyes’ level. Finally, our results showed that these typical kinematic variations are implicitly processed during social interaction and that they can trigger spontaneous social intention attribution. Interestingly, the ability of participants to access others’ mental states from motor action variations is strongly related to their explicit mentalizing performances. In sum, this thesis provides the first experimental evidences supporting the possibility to spontaneously access to others’ social intentions from perceptive and motor processes.
