Florent Levillain is a researcher in cognitive psychology at CHArt-LUTIN Userlab. During his thesis, he studied mental imagery and the understanding of dynamic scenes, conducting research both at the International School for Advanced Studies (Trieste, Italy) and at the Paris 8 Saint Denis University. After a postdoctoral fellowship at the Johns Hopkins University where he examined the limitations of short-term memory as well as the perception of causal relationships, Florent Levillain resumed an investigation of the interpretation of action. What are the motion cues that enable an event to be perceived? Which cognitive systems contribute to the spontaneous understanding of behavior in terms of intentional actions? These questions are brought up in the context of a collaboration with the Diip Ensadlab at The Ecole Nationale Supérieure des Arts Décoratifs in Paris.
