The Ego and the Mechanisms of Defense by Anna Freud Publisher: East China Normal University Press

Introduction
The Ego and the Mechanisms of Defense is an important work in the field of psychoanalysis. It has been popular for 80 years since its publication. The book is roughly divided into three parts, each of which has groundbreaking contributions. In the first part, Anna Freud pioneered the establishment of the self as the task of psychoanalysis, and explained that the unconscious derivatives that appear in consciousness and behavior are also the objects of psychoanalysis. In the second part, Anna Freud systematized the psychoanalytic knowledge of defense mechanisms, sorted out the defense mechanisms discussed in her father's works, further proposed new defense mechanisms, and explained their working principles in a broader model of personality development and psychopathology. In the third part, Anna Freud examined adolescence, a stage of psychological development that was neglected by early psychoanalysis.

In 1952, she founded the Hampstead Child Therapy Clinic, now the Anna Freud National Center for Children and Families.
