The Laboratoire des Systèmes Perceptifs (LSP) is a research unit (CNRS UMR 8248) within the Institut d’étude de la cognition (IEC) at the Ecole Normale Supérieure, Paris.

Members of the unit are interested in understanding the mechanisms underlying our perception of the world, with an emphasis on vision and audition. For this purpose, we harness tools from multiple disciplines, in particular behavioural psychophysics, integrative neuroscience, and computational modelling. Recent efforts have focused on the investigation of predictive coding, scene analysis, and dynamic sensory processes, both on fundamental and applied grounds.
