What is the total number of stages in Erikson's theory of development?

Erikson's theory of psychosocial development outlines eight distinct stages that individuals progress through from infancy to late adulthood. Each stage presents a central conflict or challenge that must be addressed, contributing to the development of a healthy personality and acquiring basic virtues.

The eight stages include:

1. Trust vs. Mistrust (infancy)

2. Autonomy vs. Shame and Doubt (toddlerhood)

3. Initiative vs. Guilt (preschool age)

4. Industry vs. Inferiority (school age)

5. Identity vs. Role Confusion (adolescence)

6. Intimacy vs. Isolation (young adulthood)

7. Generativity vs. Stagnation (middle adulthood)

8. Integrity vs. Despair (late adulthood)

Each of these stages plays a crucial role in shaping an individual's psychosocial development, with successful resolution leading to a healthier social and emotional life. The identification of eight stages provides a comprehensive framework for understanding human development across the lifespan, highlighting the importance of social relationships and personal growth in achieving a well-rounded identity.
