Abstract : Interactions in teamwork and their efficiency are based on a hierarchical system including verticale dyads. This research studies leadership through the social roles link to the hierarchical status of the vertical dyad (i.e., leader for the chief and follower for the subordinate).The influence of follower on leader and leadership is increasingly considered. However, the follower’s behaviors are still unexplored. This multidisciplinary doctoral work (i.e., psychology and affective computing) tries to highlight the influence of follower’s behavior on the leader, and the underlying process of this influence.To do so, we used the follower’s nonverbal behaviors (CNV) as the social clues that can influence the leader and his behaviors. The principles of social cognition are applied in this thesis to study the cognitive evaluation made by the leader. We worked on the activation of the caracteristics used to categorize followers, the implicit followership theories (IFTs).The study of the cognitive evaluation made by the leader comes we multiple issues, including methological ones. Thus, a preliminary work of translation and validation of a scale evaluating the IFTs was realized.The first exploratory study used images of virtual agents displaying CNV that could explicitly activate leaders’ IFTs. We complete these result through an analysis of a corpus of videos filming medical teams’ training. This study allowed us to observe dynamic CNV that could influence the perception of followership. In a third study, we implemented the CNV of the two previous studies in a virtual agent. Medical leaders had to interact with it, and implicit activation of IFTs was collected using a Go / No Go protocol. Finally, using a quantitative approach, we studied the influence of cognitive evaluation of the leader on his leadership behaviors.Results suggest that some caracteristics displayed in CNV (i.e., dominance and support) can activate the leaders’ IFTs. Moreover, the cognitive evaluation of the leader seems to influence his leadership behaviors.We will discuss the results and explain the scientifical and pédagogical contributions of this thesis. We will analyse our problematic through multiple angles, including the epistemologycal point of view allowing the study of IFTs, and the use of virtual agents in the research field of categorization process. The practical application of the doctoral work is the implementation of CNV in virtual subordinates for the deployement of a serious game for medical team leader.
