Which of the following is NOT a Piaget stage of cognitive development?

• A. Linguistic stage
• B. Sensorimotor
• C. Preoperational
• D. Concrete operational

Answer: (A)

Piaget’s theory outlines four major stages of cognitive development, each representing a qualitative shift in how children think: Sensorimotor, where understanding comes through physical interaction with the world; Preoperational, where symbolic thinking grows but logic is still limited and egocentrism can be present; Concrete Operational, where logical thinking emerges about concrete objects and events; and Formal Operational, where abstract and hypothetical reasoning develops. A stage focused specifically on language does not exist in Piaget’s framework. Language develops and becomes more sophisticated within these stages, supporting thinking, but Piaget did not describe a separate “linguistic” stage. The other options listed are all recognized Piaget stages, while the linguistic one is not.
