James M Yearsley

Postdoctoral fellow
Research Area: Cognition and Cognitive Neuroscience

James has a background in theoretical physics, with a PhD from Imperial College London and post doc experience at the University of Cambridge. He moved to cognitive science to work on physics inspired models of cognition, particularly models of judgment and decision making based on the mathematics of quantum theory. More generally, he is interested in the way particular cognitive models might either be derived from underlying neural behaviour, or deduced as specific instances of a more general information processing framework.
