A renowned expert in nonverbal communication, Paul Ekman has led a revolution in our scientific understanding of emotions. Now he assembles his pathbreaking research and theories in a comprehensive look at human emotional life. Emotions Revealed explores the evolutionary essence of anger, sadness, fear, surprise, disgust, contempt, and happiness. Drawing on his fieldwork investigating universal facial expressions in Papua New Guinea and his analysis of the prognosis of hospital patients based on their emotional profile, Ekman shows that emotions are deeply imbedded in the human species. In the process, he answers such questions as: What triggers emotions and can we stop them? How does our body signal to others whether we are slightly sad or anguished, peeved or enraged? Can we learn to distinguish between a polite smile and the genuine thing? Unique exercises and photographs help readers identify emotions in themselves and others. Emotions Revealed is a practical, mind-opening, and potentially life-changing exploration of science and self.
