Which sequence correctly lists Piaget's stages in the order described in the material?

• A. Sensorimotor, Preoperational, Concrete Observational, Formal Operation
• B. Sensorimotor, Concrete Observational, Preoperational, Formal Operation
• C. Preoperational, Sensorimotor, Concrete Observational, Formal Operation
• D. Sensorimotor, Concrete Operational, Formal Operation, Preoperational

Answer: (A)

Piaget’s stages advance from infancy to adolescence in a fixed progression: sensorimotor, preoperational, concrete operational, then formal operational. In the sensorimotor stage, infants learn through actions and senses and develop object permanence. The preoperational stage follows, with growing language and symbolic thinking but limited logic and egocentrism. The concrete operational stage comes next, where children begin logical thinking about concrete objects and understand concepts like conservation. Finally, the formal operational stage brings abstract and hypothetical reasoning. The correct sequence mirrors that exact order, even if one term uses a slightly different label (Concrete Operational may appear as a variant). The other sequences reorder stages or mislabel them, which does not fit the established progression.
