Lisa Feldman Barrett, PhD, is among the top 0.1% most cited scientists in the world for her revolutionary research in psychology and neuroscience. She is a University Distinguished Professor of Psychology at Northeastern University. She also holds appointments at Harvard Medical School and Massachusetts General Hospital, where she is Chief Science Officer for the Center for Law, Brain & Behaviour. In addition to academic work, Barrett has written two science books for the public, How Emotions are Made and Seven and a Half Lessons About the Brain. This episode begins with Lisa talking about how the brain's processes can help overcome anxiety related to public speaking, and how sensations interpreted as anxiety can be redefined as determination or arousal through cognitive reframing. Peter and Kasia explore the philosophical implications of neuroscience concepts such as free will and the self, the construction of social reality, and environmental influences on leading a meaningful life.
