Ben Alderson-Day is an associate professor of psychology and a fellow of the Wolfson Research Institute for Health and Wellbeing at Durham University. He joins host Krys Boyd to discuss the psychology and neuroscience of feeling watched or hearing voices as he tries to unravel a phenomenon felt by people the world over.
