Piaget’s Preoperational Stage

In Jean Piaget’s analysis of child cognition, a child goes through four stages of development:

  1. sensorimotor
  2. preoperational
  3. concrete operational
  4. formal operational
  5. Children in the second stage have difficulties with conservation; that is, they can’t accurately differentiate shape, number, and volume. As the video below demonstrates, the preoperational stage is also the most adorable.

    P.S.: Apparently I didn’t have a post prepared yesterday! Sorry about that, loyal readers. I am bad at queuing.
