Intuitive physics in visual perception

Résumé : My research investigated intuitive physics in adult visual perception through behavioral measures. I focused on the physical constraint of solidity (i.e., solid objects cannot pass through each other). In my first study, I discovered that solidity is indeed embedded in the visual system, shaping our perception of object motion. My second study investigated the limits of the solidity constraint in vision, showing that it can be overridden by the stereo-scopic cue of depth in the context of the Pulfrich effect.

Generalized Shape Metrics on Neural Representations

Understanding the operation of biological and artificial networks remains a difficult and important challenge. To identify general principles, researchers are increasingly interested in surveying large collections of networks that are trained on, or biologically adapted to, similar tasks. A standardized set of analysis tools is now needed to identify how network-level covariates -- such as architecture, anatomical brain region, and model organism -- impact neural representations (hidden layer activations).
