Erikson's stages of psychosocial development

Erikson's stages of psychosocial development, as articulated in the second half of the 20th century by Erik Erikson in collaboration with his wife Joan Erikson, is a comprehensive psychoanalytic theory that identifies a series of eight stages that a healthy developing individual should pass through from infancy to late adulthood. According to Erikson's theory the results from each stage, whether positive or negative, influence the results of succeeding stages.
