During which stage do children begin to learn about their world through actions?

• A. Concrete-Operational
• B. Preoperational
• C. Formal Operations
• D. Sensorimotor

Answer: (D)

The key idea is that learning about the world through actions is the sensorimotor stage. In this early stage, infants understand their world by directly interacting with it—grasping, looking, mouthing, shaking, and moving objects to see how they respond. They start with reflexes and then increasingly coordinate their actions to explore cause and effect. A crucial milestone here is object permanence: understanding that things continue to exist even when not seen, which builds from those action-based explorations. Other stages move toward thinking with symbols, language, and logical operations, rather than relying primarily on physical actions, so the sensorimotor stage is the period dominated by learning through action.
