What is "ego psychology"

Ego psychology is a school of psychoanalysis rooted in Sigmund Freud's structural id-ego-superego model of the mind.

An individual interacts with the external world as well as responds to internal forces. Many psychoanalysts use a theoretical construct called the ego to explain how that is done through various ego functions. Adherents of ego psychology focus on the ego's normal and pathological development, its management of libidinal and aggressive impulses, and its adaptation to reality.
