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. As the baby watches, the experimenter covers the object so that it is out of sight. If the baby searches for the object under the cloth she demonstrates that she has a sense of the continued existence of absent objects.
