Dr. Stocker's work is aimed at understanding how our visual percept of the world is shaped by our beliefs and expectations about what there is to be perceived. Using both theory and experiments, research in his laboratory explores how the statistical properties of our visual environment shape our expectations (i.e. objective expectations), and how our expectations reflect our own previous perceptual decisions (i.e. subjective expectations). He is a faculty member in the Department of Psychology and teaches PSYC111 (Perception).
