Which theorists are commonly associated with stage theories of development?

The correct answer highlights Piaget and Erikson, who are both prominent figures in psychology known for their influential stage theories of development. Jean Piaget is famous for his cognitive development theory, which outlines specific stages that children go through as they learn about and interact with the world. These stages are characterized by increasingly complex levels of reasoning and understanding, such as the sensorimotor, preoperational, concrete operational, and formal operational stages.

Erik Erikson, on the other hand, is known for his psychosocial development theory, which identifies eight distinct stages of human development that encompass not just childhood, but the entire lifespan. Each stage is characterized by a specific conflict that individuals must resolve to develop a healthy psychological state.

Both theories emphasize that development occurs in progressive, stage-like sequences and each stage has particular characteristics and tasks that influence subsequent stages. This aligns with the overall concept of stage theories in development—representing qualitative changes at different life phases.

The other theorists listed do not focus on stage-based frameworks in the same vein. Freud's psychosexual stages offer a different perspective, focusing on childhood and drives but not in the context of broader development across the lifespan. Skinner and Watson are more associated with behaviorist approaches, concentrating on observable behaviors
