Quizplus · Accepted Answer

Piaget's theory of cognitive development suggests that object permanence, or the understanding that objects continue to exist even when they are not visible, is not fully developed until around 8-9 months of age. Therefore, your niece may not yet have completely understood that you still exist even when you cover your face with a blanket.
