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). |
