Which developmental stage according to Jean Piaget involves learning through sensory perception?

The developmental stage that involves learning through sensory perception is the Sensorimotor stage. This stage, which typically occurs from birth to approximately two years of age, is characterized by infants learning about their environment primarily through their senses and their motor actions. During this time, babies explore the world by touching, seeing, hearing, and moving, and they begin to develop an understanding of object permanence—the realization that objects continue to exist even when they cannot be seen.

In contrast, the Preoperational stage, which follows Sensorimotor development, is marked by the development of language and symbolic thinking but is limited in logical reasoning. The Concrete Operational stage introduces logical thinking and the ability to perform operations on concrete objects, while the Formal Operations stage involves abstract reasoning and the ability to think about hypothetical situations. None of these later stages primarily emphasize learning through sensory perception in the same foundational way that the Sensorimotor stage does.
