In contrast with most introductions to the study of psychology, this book is written primarily from the viewpoint of freudian psychoanalytic theory and based principally upon psychoanalytic literature. Presenting the findings of clinicians rather than those of experimentalists, the writer draws upon the experience of Abraham, Ferenczi, Rank, Jones, Alexander, Reik, Klein, Isaacs, Fenichel and other psychoanalysts. He includes the views of only a few of the psychologists who have made contributions to dynamic principles, among whom are James, Woodworth, Wertheimer, Koehler, Koffka, and Kurt Lewin.
