Answer:
things continue to exist even when they are not perceived.
Step-by-step explanation:
Object permanence has to do with the realization that the existence of objects persists even though they cannot be seen, heard or touched. Swiss psychologist Jean Piaget used to believe that object permanence had to do with the babies' motor system development. However, he then suggests that children establish object permanence perception through the sense of tact and manipulation of objects.
