Stages

Differences

Piaget’s four stages of a child’s development are the sensorimotor stage, from birth to when they begin to speak about age 2, the preoperational stage, between ages 2 to 7, the concrete operational stage, between ages 7 and 11, and the formal operational stage, from adolescence to adulthood. These are at best useful generalizations. Different children develop different skills in different domains (logic versus language, for example) at different rates, sometimes by chance.
