The original edition of Emotion in the Human Face, published in 1972, was the first volume to evaluate and integrate all the research on facial expression of emotion since Darwin’s The Expression of Emotions in Man and Animals was published in 1872. It presented a detailed, critical discussion of research involving the face and emotion, focusing on the complex conceptual and methodological issues involved, and settling many past controversies, such as whether the face provides accurate information about emotion, and whether some facial expressions are universal. In 1982, Dr. Ekman expanded, reorganized, annotated, and cross-referenced the contents of the first edition, bringing the review of basic research up to date and charting the new developments in the field.
