I believe the answer is: A close parent–child bond motivates children to listen to parents. 
in a close parent-child bond, we teach children to follow the parents' instruction and perspective in order to obtain certain level of affection.
Since in this relationship requires the children to constantly make an effort to fulfill the expectation of the parents, the children need to have low anxiety and able to handle disapproval.
