Piaget's Four Stages
Captions available
The idea
Piaget described four stages taken in a fixed order, sensorimotor, preoperational, concrete operational and formal operational; preoperational children fail conservation because of centration and irreversibility.
In practice
Poured into a tall thin glass, the same juice seems like more to a four-year-old.
Where people slip
The ages are approximate; the order is the theory's firm claim.
