What is the correct order of Piaget's four cognitive development stages from earliest to latest?

• A. Sensorimotor → Preoperational → Concrete Operations → Formal Operations
• B. Preoperational → Sensorimotor → Formal Operations → Concrete Operations
• C. Conservation → Assimilation → Accommodation → Piaget Four Stages
• D. Formal Operations → Sensorimotor → Preoperational → Concrete Operations

Answer: (A)

Piaget’s thinking becomes gradually more complex as children move from practical action to abstract reasoning. In the earliest stage, infants learn about the world through their senses and actions, tracking objects they can see or touch and eventually realizing objects continue to exist even when not in view. Next, children gain language and symbolic thinking but still think in a very here-and-now, egocentric way, often struggling with logic that operates on transformations. Then they begin to use logic with concrete objects and events, understanding ideas like conservation and reversibility. Finally, they develop the ability to think abstractly and reason about hypothetical situations. This sequence—sensorimotor, then preoperational, then concrete operational, and finally formal operational—reflects the progressive buildup of cognitive complexity. Other sequences mix up the order or treat concepts like conservation or the processes of assimilation and accommodation as stages, which isn’t how Piaget organized the theory.
