Question

Your little brother has a big ball of clay. While he watches, you roll the ball of clay into a long snake-like shape. He begins to cry because he thinks he has less clay now. Which of Piaget's stages is your brother likely to be in?

Answer 1

My brother would belong to the Pre-operational from Piaget stages.

Basically, Piaget's four stages of intellectual (or cognitive) development are:

Sensorimotor. Birth through ages 18-24 months.
Preoperational. Toddlerhood (18-24 months) through early childhood (age 7)
Concrete operational. Ages 7 to 12
Formal operational. Adolescence through adulthood.

Where are the choices that I have to choose from? Anyway, I'll just provide a detailed answer to your question.
