Hidden Object Test

A research technique invented by Piaget to assess object permanence in infants from 6 months old. An interesting object, like a small toy, is placed in front of a baby within her reach.

If the baby searches for the object under the cloth she demonstrates that she has a sense of the continued existence of absent objects.
