The developmental theory of Erik Erikson builds upon and extends Sigmund Freud's classical account of psychosexual stages. Noteworthy in this regard is the fact that Erikson was analyzed and influenced by Freud's daughter, Anna. According to orthodox Freudian psychoanalytic theory, personality development is completed by at least adolescence and is relatively independent from positive environmental influences. Moreover, ego development is considered to be defensive in nature; the ego emerges to control and regulate the id, which comprises biologically determined instincts, needs, urges, and the like.
