Which Piaget stage lasts from birth to about 2 years and is characterized by learning through movement and sensation?

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

Answer: (B)

The main idea here is Piaget’s first stage of cognitive development, when infants learn by moving and sensing their world. In this period, babies start with reflexes and gradually combine sensor input with motor actions, turning simple behaviors into intentional exploration. A key milestone is object permanence—the understanding that objects still exist even when they aren’t visible. This stage spans from birth to about two years, ending as symbolic thought and more advanced reasoning begin to emerge. The other stages describe thinking that uses symbols, concrete logical operations, or abstract reasoning, which appear later in childhood and don’t capture infancy’s learning through movement and sensation.
