Question

Quizplus · Accepted Answer

At around 9 months, babies begin to understand object permanence, the idea that objects still exist even when they are out of sight. By hiding the toy behind the pillow instead of under the blanket, Kevin's mother is testing his understanding of object permanence. The fact that Kevin looks under the blanket instead of behind the pillow suggests that he has not yet fully grasped this concept, which is typical for a 9-month-old.
