RESEARCH ACTIVITY

Our research aims at identifying the mechanisms that underlie the abilities to infer mental states from other people's behaviour. As social interactions are by essence dynamic, mental states are described here as the desires, emotions, beliefs and intentions that are reflected in human actions. It was recently proposed that an automatic motor simulation process of perceived nonverbal behaviours underpins a primitive and implicit form of understanding of other people's mental states, and therefore is one of the core components of mind-reading abilities. However, our initial assumption is that there are inter-individual differences in the efficiency of this process; and secondly that mind-reading abilities cannot be reduced to motor simulation. Rather, it entails a broader understanding that involves studying the coupling between the representations of other people's actions, intentions and affective states.

Our central concerns are to identify the neurobiological bases of intentional and emotional body movements and to investigate the functional significance of communication of intention and emotion through body movements. The goal is to assess the degree of interaction between the representations of other people's actions, intentions and affective states, taking into account individual differences (motor experience and social abilities) and contextual effects (such as personal involvement) that impact on these interactions.

In collaboration with Pr. B. de Gelder, we investigate the neural basis involved during the perception of body expressions of emotions and its link with motor preparation. In parallel, we explore the abilities to infer mental states (intentions, false belief and emotions) through the perception of other people's behaviour in people with Asperger syndrome, in collaboration with Dr B. Wicker and Dr S. Berthoz. These projects combine several approaches, behavioural (performances and reactions times), physiological (such as skin conductance) and neuromimaging techniques (fMRI and EEG).

Keywords : Action & perception, intentions, emotions, fMRI, social neurosciences.
