In which stage do infants learn primarily through senses and motor actions, such as looking, listening, touching, mouthing, and grasping?

• A. Sensorimotor
• B. Preoperational
• C. Concrete operational
• D. Formal operational

Answer: (A)

Infants learn about the world through direct sensory input and their own motor actions—looking, listening, touching, mouthing, and grasping. This describes the sensorimotor stage, which lasts roughly from birth to about two years old. In this period babies start with reflexes and gradually turn those actions into purposeful behaviors as they explore how their movements affect the world around them. A key milestone is object permanence—the understanding that objects continue to exist even when not in view—which develops through ongoing sensorimotor interaction. As they move beyond mere reflexes toward more complex coordination of senses and actions, thinking becomes more concrete and later branches into symbolic thought and language, marking progression to the next stages. In contrast, the preoperational stage emphasizes pretend play and language without solid logical operations on objects, the concrete operational stage centers on logical reasoning about concrete objects, and the formal operational stage involves abstract reasoning.
