While people have known for centuries that facial expressions can reveal what people are thinking and feeling, it is only recently that the face has been studies scientifically for what it can tell us about internal states, social behavior, and psychopathology. Today, because sophisticated measuring systems are more widely available, a wealth of new research on facial behavior has contributed enormously to our understanding of human psychology. The chapters in this volume represent the state-of-the-art in the study of facial expression. They address key topics and questions such as the dynamic and morphological differences between voluntary and involuntary expressions, the relationship between what people show on their faces and what they say they feel, whether it is possible to use facial behavior to draw distinctions among psychiatric populations, and the latest research on automating facial measurement. The book also includes updated commentary by the authors on any contributions appearing previously and a concluding integration and critique of all the contributions by Paul Ekman.
Paul Ekman was a Professor of Psychology for 32 years in the Department of Psychiatry at the University of California at San Francisco. He also served as chief psychologist in the U.S. Army, Fort Dix New Jersey from 1958-1960. His interests have focused on two separate, but related topics: He originally focused on nonverbal behavior, and by the mid-60s concentrated on the expression and physiology of emotion. His other interest is interpersonal
deception. His research program was supported by grants from the National Institute of Mental Health, the National Science Foundation, and the Advanced Research Projects Agency of the DOD, loosely affiliated with UCSF. His many honors have included the Distinguished Scientific Contribution Award of the American
Psychological Association in 1991, and an honorary doctor of humane letters from the University of Chicago in 1994. Dr. Ekman retired from UCSF in 2004.
