Erikson's stages of psychosocial development are based on the theory that individuals pass through eight stages of psychosocial development, each characterized by a unique developmental task that must be successfully resolved to progress to the next stage.

Erikson believed that successful resolution of each stage contributes to a person's overall psychological well-being and personality development.
