## Piaget's Stages of Cognitive Development | Stage | Age Range | Key Features | Cognitive Milestones | |---|---|---|---| | 1. Sensori-Motor Stage | Birth to 2 years | Development through sensory experiences and movement. | Reflexes, habits, object permanence, intentional actions, curiosity, and increased mobility. | | 2. Pre-Operational Stage | 2 to 7 years | Symbolic thinking, fantasy, and intuitive thoughts dominate. | Pretend play, symbolic representation, primitive reasoning, egocentrism, and curiosity ("Why" stage). | | 3. Concrete Operational Stage | 7 to 11 years | Logical thinking and concrete cognitive operations emerge. | Inductive reasoning, conservation, reversibility, classification, and understanding others' perspectives. | | 4. Formal Operational Stage | 12+ years | Rational and abstract thinking, hypothetical reasoning, and planning. | Deductive reasoning, abstract concepts, philosophical thinking, identity formation, and compassion. | ### Additional Information Jean Piaget was a Swiss psychologist known for his groundbreaking work in cognitive development. He published his first scientific paper on albino sparrows at the age of 11. In 1920, he began working with intelligence tests, discovering that younger children think differently than older children. Piaget emphasized that while lifelong learning is possible, the formal operational stage is the final stage of cognitive development.
