Research Theme

Our primary interest is to study the neural time course and correlates underpinning the processing of the early stages of social interactions. We have now set out to address several key issues important to our understanding of the processing of social interactions, for example (i) what is the biological function of spontaneous and involuntary facial reactions when facing emotional events; (ii) how and when do we perceive / decide that we are the target of a communicative intention (iii) how we (decide to) prepare an adapted motor response. We combine several approaches, behavioural (performances and reactions times), psycho-physiological (such as skin conductance, heart rate and facial EMG) and neuroimaging techniques (fMRI and EEG) in healthy individuals and in individuals with an Autism Spectrum Disorder.
