When asked where the sun goes at night, four-year-old Kiet explains to his dad that it goes to sleep. Later that day, Kiet gets upset because he believes his sister's glass contains more juice than his glass. Both glasses actually contain the same amount of juice, but Kiet is confused because of the tall and thin shape of his sister's glass. From these instances, we can say that Kiet is in the stage of Piaget's cognitive development.

Preoperational stage of Piaget's cognitive development.
