Erikson's stages of psychosocial development include eight stages ranging from birth to old age.

The first of Erikson's stages of psychosocial development details the challenge of finding security and learning to trust oneself and one's environment.

These stages were called the Erik Erikson's Stages of Psychosocial Development.

Erikson's stages of psychosocial development describe progression into adult maturity, with each maturational stage characterized by a certain kind of psychsocial conflict.

Unlike some other theories of development such as Erikson's stages of psychosocial development, it is not assumed that even a majority of people progress through all levels.

In Erik Erikson's Stages of Psychosocial Development, generativity is a struggle against stagnation that ascends during adulthood.

Erik Erikson's stages of psychosocial development expanded on Freud's psychosexual stages, he defined eight stages that describe how individuals relate to their social world.

Erikson's stages of psychosocial development, as articulated by Erik Erikson, explain eight stages through which a healthily developing human should pass from infancy to late adulthood.

This stage was developed by George Vaillant in 1977 and added to Erikson's stages of psychosocial development, between intimacy vs. isolation and generativity vs. stagnation.

Examples of some theories are Daniel Levinson's theory of life structure, Lawrence Kohlberg's stages of moral development, and Erik Erikson's stages of psychosocial development.

Each of Erikson's stages of psychosocial development is marked by a conflict for which successful resolution will result in a favourable outcome, and by an important event that this conflict resolves itself around.

Erik Erikson's stages of psychosocial development can also be seen in the choices Boy makes vs. the choices Dunstan makes (e.g. Boy chooses intimacy while Dunstan chooses isolation).

Optimal human development generally occurs in identifiable stages (e.g., Jean Piaget's theory of cognitive development, Erik Erikson's stages of psychosocial development, John Bowlby's attachment framework, and other developmental stage theories).

Other theories on personality development include Jean Piaget's stages of development, Erik Erikson's stages of psychosocial development, and personality development in Sigmund Freud's theory being formed through the interaction of id, ego, and super-ego.

Wilber's conception of the level is clearly based on several theories of developmental psychology, including: Piaget's theory of cognitive development, Kohlberg's stages of moral development, Maslow's hierarchy of needs, Erikson's stages of psychosocial development, and Jane Loevinger's stages of ego development.
