eliminate a designated behavior by strengthening other behaviors that are incompatible with it.
Pamela is constantly late getting home for supper. Her parents could punish her for her tardiness; and if punishment is effective, she will stop being late. On the other hand, her parents could take the opposite course of action and reward her for getting home on time. If the reward is effective, Pamela will develop the habit of arriving on time for supper; and since being on time is the opposite of being late, Pamela's problem of lateness thus could be eliminated without punishment. (Whether or not Pamela's parents would actually want to choose this second course of action would depend on several factors which will be discussed later in this section.)
