The final stage of Piaget's cognitive-developmental theory, suitable for ages 11 and up, is called which?

• A. Formal Operational Stage
• B. Sensorimotor Stage
• C. Preoperational Stage
• D. Concrete Operational Stage

Answer: (A)

Piaget's thinking evolves from concrete experiences to abstract reasoning, and the final stage that emerges around ages 11 and up is the Formal Operational Stage. In this stage, thinking becomes abstract and hypothetical. Adolescents can reason about possibilities, test hypotheses systematically, and handle abstract concepts like algebra, ethics, and future planning without needing concrete objects. This distinguishes it from earlier stages, where thought is more tied to direct experience: the sensorimotor stage relies on sensing and acting; the preoperational stage uses symbols but shows egocentrism and limited logical operation; and the concrete operational stage handles logical thinking about concrete objects but not abstract ideas.
