Answer :
Answer:
The kids' different responses most likely reflect differences in:
B) Object permanence
Explanation:
Even though they are only four months apart in age, Emmanuel's brother and niece already show differences in object permanence. Object permanence is a child's ability to understand that an object continues to exist, even though it can no longer be seen. To the 4-month-old niece, once the blocks were put away, she no longer thought of them. It's as if they don't exist anymore. To the 8-month-old brother, the blocks still exist. He understands they have been placed inside a box by Emanuel. Thus, the brother has already developed object permanence, while the niece hasn't.
