This updated edition adds some new definitions of the emotions, new developments in emotional theory, selected additional references, and a new preface. In its basic volume it outlines in detail a model of primary emotions and their mixtures. It also examines the various problems that have plagued research in this area and shows how the model helps to resolve and clarify these issues. Using material from both psychoanalytic and behavioristic sources, as well as other theoretical viewpoints, this book remains a very comprehensive and valuable study. Originally published by Random House in 1962.
