Question

Quizplus · Accepted Answer

Object permanence refers to the understanding that objects continue to exist even when they cannot be seen or heard. The A-not-B error is a common test used to assess object permanence in infants and toddlers. When toddlers avoid the A-not-B error - which involves hiding an object in one location (A) several times and then moving it to a new location (B) - they demonstrate that they understand that the object still exists, even though it is not in the original hiding spot. Therefore, choice (A) is the best answer.
