Why is object permanence a giant step in intellectual development?

Object permanence is a crucial milestone in intellectual development because it signifies a child's ability to understand that objects continue to exist even when they are not visible. This cognitive skill, typically developed by around 8 to 12 months of age, lays the foundation for more complex thinking, problem-solving, and memory. It enhances a child's understanding of the world, allowing them to anticipate events and interact more effectively with their environment. Furthermore, mastering object permanence fosters social and emotional development, as it helps children form attachments and engage with caregivers more meaningfully.
