I think it has to do with their peer's actions/responses. If they put off homework/studying for a test to the last minute then that child will do the same. Most children's psychology is conformity and wanting to fit in with their friends. That is why the saying "choose your friends wisely" exists, you want to have friends that have the same values as you. In this case, you want a peer group that does their homework and studies for their tests so they can help you be better academically.
