This book presents an integration of psychoanalytic theories of human development from Freud to the present, showing their implications for the evaluation and treatment of children and adults. The authors not only review the literature on emotional growth but also provide a developmental theory of their own, one that examines psychosexual development in the context of a number of other simultaneously evolving systems - emotional, behavioural, cognitive, and social - all of which work in relation to one another in a dynamic way. They describe the developmental sequences of these systems and how they coalesce to form the human personality.
