Large modifications of analytic technique are a flight from the Oedipal conflict. But in the author's observations of analysts with widely divergent theoretical orientation, impressive therapeutic results are achieved so long as the primary importance of transference analysis is recognized. Recent developments mainly concern ego psychology, the significance of object relations, the role of aggression, and the part played by regression and repetition-compulsion in the transference. Zetzel examines various theories about the elements that constitute the essence of transference and the factors that lead to therapeutic change.
