Which of the following are the main stages of human development according to Erikson's psychosocial theory?

Erikson's psychosocial theory delineates eight distinct stages of human development that span from infancy to old age, each characterized by a central conflict that individuals must navigate to develop a healthy personality and social skills. The correct answer includes all eight stages:

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)

These stages are crucial as they outline the primary psychosocial challenges faced at each life phase, illustrating how successful navigation contributes to a well-adjusted adult.

In contrast, the other choices do not encompass the entirety of Erikson's framework. Some are incomplete, omitting key stages, such as identity formation during adolescence or generativity in middle adulthood, both significant aspects of personal development later in life. Others offer incorrect stages from different developmental theories, such as the cognitive stages proposed by Piaget,
