Final answer:
Scott can now comprehend that objects continue to exist even when out of sight, thanks to achieving object permanence, a crucial cognitive development stage according to Piaget's theory. This understanding allows him to participate in games like hide and seek and comprehend the return of people who leave his field of vision.
Step-by-step explanation:
Because Scott has recently achieved object permanence, he will now be able to understand that objects continue to exist even when they are not in sight. For example, if his favorite toy is covered with a blanket, Scott recognizes that the toy is still there and will likely try to uncover it. This developmental milestone, which typically occurs around 8 months of age, indicates a critical advancement in cognitive development according to Jean Piaget's theory.
Scott's acquisition of object permanence means he can engage in activities like hide and seek, and he will have the understanding that when someone leaves the room, that person still exists and will eventually return. This concept extends to objects as well; he will look for them in appropriate places if they are hidden from view. The realization that the world does not vanish when it becomes unseen is a foundational block for more complex cognitive processes.
