On today’s Please Explain we’ll look into how hypnosis works, and how it can be effective in treating people who want to stop smoking, lose weight, or calm their nerves before a test. We’re joined by Dr. Roberta Temes, hypnotist, psychologist, and author of The Complete Idiot’s Guide to Hypnosis; and Dr. Amir Raz, Professor in the Departments of Psychiatry, Neurology and Neurosurgery, and Psychology, and Canada Research Chair in the Cognitive Neuroscience of Attention, at McGill University and SMBD Jewish General Hospital.
