Which Piaget stage is described as birth through 2 years, learning through physical interaction?

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

Answer: (A)

This question taps into Piaget’s stages of cognitive development and which period matches infancy. From birth to about age two, children learn mainly through their senses and motor actions—grabbing, sucking, looking, moving objects, and otherwise interacting physically with the world. This is the sensorimotor stage, where understanding grows as actions produce real effects and as infants begin to coordinate sensory input with movement. A key milestone here is object permanence—the realization that objects exist even when they aren’t visible—which shows how thinking moves from immediate, concrete actions to more intentional exploration. By the end of this stage, infants also begin to show the beginnings of symbolic thought, but their thinking remains deeply rooted in concrete, hands-on experiences.

The other stages describe different patterns of thinking that appear later: the preoperational stage involves language development and pretend play but still lacks logical operations; the concrete operational stage introduces logical reasoning about concrete objects and events; the formal operational stage brings abstract and hypothetical reasoning.
