Step-by-step explanation:
The behavior of Nicholas coming home late for supper decreased to zero after his parents started taking away a dollar of his allowance every time he was late. This is an example of response cost, which is a form of negative punishment. Response cost involves the removal of a valued item or privilege in order to decrease an undesirable behavior.
