Many people hear voices that aren’t really there. It drives some to seek psychiatric treatment, but others are able to make use of it in healthy ways. In this episode, Al Powers and Phil Corlett from Yale University talk about their research into the similarities and differences between these two groups, and what the rest of us can learn from their experiences. They tell their stories behind developing their article “Pavlovian conditioning–induced hallucinations result from overweighting of perceptual priors,” which they co-authored with Chris Mathys, published in the August 2017 issue of the journal Science.
