This book focuses on the crucial importance of developmental work to psychotherapy and psychopathology. It offers an account of psychotherapy to integrate scientific knowledge of psychological development and represents psychological states in the minds of infants, children, adolescents, and adults.

In a brilliant examination of the frontiers of human emotion and cognition, four prominent psychoanalysts combine the perspectives of developmental psychology, attachment theory and psychoanalytic technique. The result of this marriage of disciplines is a bold, energetic and ultimately encouraging vision for the psychoanalytic treatment.
