Which developmental theory emphasizes the role of stages in child development?

The emphasis on stages in child development is a hallmark of Erikson's Psychosocial Theory. Erik Erikson proposed a model consisting of eight distinct stages, each characterized by a specific conflict or challenge that individuals must navigate to develop a healthy personality and social relationships. This stage-based approach means that development progresses through a sequence of critical periods, with each stage building upon the outcomes of preceding ones.

In contrast, while both Piaget's Cognitive Theory and Kohlberg's Moral Development Theory also present specific frameworks for understanding growth, they do not emphasize psychosocial stages in the same way Erikson does. Piaget focused primarily on cognitive development and the processes through which children gain an understanding of the world, while Kohlberg outlined stages of moral reasoning. Vygotsky's Sociocultural Theory centers on the influence of social interactions and culture on cognitive development without a clear stage progression.

Thus, Erikson's theory distinctly stands out for its focus on different stages of psychosocial development throughout an individual's life.
