In her 25 years of research, psychology professor Lisa Feldman Barrett has delved into the depths of emotions by studying facial expressions, brain scans, and numerous physiology studies. Her extensive work has uncovered what emotions truly are and how they affect us. From happiness to anxiety, Barrett examines how these emotions vary from person to person and challenges the notion that we all experience them similarly. With fascinating insights, she shares her findings and highlights how we may have more control over our emotions than we previously thought.
