Question

Quizplus · Accepted Answer

Rudy's mother capitalized on Rudy's lack of object permanence, which is the understanding that objects continue to exist even when they cannot be seen, heard, or otherwise sensed. By putting the knife out of Rudy's sight, she relied on his developmental stage where he might not yet understand that the knife still exists even though he can no longer see it.
