John McDonnell

I am a doctoral candidate at NYU working in Todd Gureckis' Computation and Cognition Lab, studying the ways in which people form psychological categories and make use of them to solve tasks. My current project is to investigate the sort of on-the-fly categories people form to understand the reinforcement contingencies in the environment, comparing human performance to mechanistic models such as SUSTAIN and ALCOVE, as well as idealized rational models. I am also interested in the neurobiological systems that underlie category-learning in a variety of contexts.
