The physical properties of the signals activating our senses are often correlated in nature;
it would therefore be advantageous to exploit such correlations to better process sensory information. Stimulus correlations can be contingent and readily available to the senses (like the temporal correlation between mouth movements and vocal sounds in speech), or can be the results of the statistical co-occurrence of certain stimulus properties that can be learnt over time (like the relation between the frequency of acoustic resonance and the size of the resonator). In my talk I will present a series of experiments demonstrating the
effects of crossmodal correspondences on multisensory processing, and their grounding in natural scene statistics.

Cesare Parise studied Experimental Psychology at the University of Milano-Bicocca (Italy), and then moved to Oxford to do his DPhil (also in Experimental Psychology) under the supervision of Charles Spence. During his DPhil, Parise also worked for the University of Trento (Rovereto, Italy) and the Max Planck Institute for Biological Cybernetics Tuebingen, Germany). After his DPhil, Parise started a post-doc in Germany under the supervision of Professor Marc Ernst, first at the Max Planck Institute for Biological Cybernetics, and then at the Department of Biology at University of Bielefeld. Parise’s research focuses on the mechanisms of multisensory integration, which he investigates using a variety of techniques including psychophysics, computational modeling, virtual environments, bioacoustics, and analyses of natural scene statistics. Parise’s work has been published in top-tier international journals, and his DPhil dissertation was awarded the best Italian doctoral dissertation in Experimental Psychology.
