Personal profile

Biography

I study sensation and perception. I primarily use psychophysics to investigate perceptual after-effects, and I use decision-making experiments to understand how changes in perception shape our predictions, perceptions, and metacognitions. Some of my studies consider these things in relationship to causality; for example, do we infer cause and effect, or can we see it? What does a predictive brain tell us about all that?
