Sensorimotor. Birth through ages 18-24 months (Explorer)

Preoperational. Toddler-hood (18-24 months) through early youth (age 7)

(children learn to think abstractly, understand symbolic concepts, and use language etc.)

Concrete operational. Ages 7 to 12 (Understanding complexities)

Formal operations: Pre-adulthood through adulthood (H ypothetical, and theoretical reasoning)
