How we change what others think, feel, believe and do
Get others to do as you wish by making them uncomfortable or unhappy until they agree.
If they do not comply in the short term, you can escalate your actions, for example taking them more often or doing things that are increasingly uncomfortable for the other person.
A child nags their parent until they get what they want. If the parent seems to ignore them, they nag more loudly, more frequently, more aggressively and then start to cry.
An interrogator keeps a prisoner awake and without food until the prisoner supplies useful information.
Do it now! Do it now! Don't wait, just do it right away!
Aversive stimulation can seem like a logical thing to do. For people with limited understanding of motivation, it can also seem like the obvious thing to do. The only problem is that it not only causes discomfort -- it also causes opposition and dislike, such that the other person may refuse to comply simply as a means of revenge and asserting their own control as a reaction against you trying to control them.
While torture is indeed aversive therapy, and even less physical means can cause great distress, more moderate forms aversive stimulation are both common and sometimes a reasonable option.
Considerations when to use this approach:
Aversive Stimulation is the eighth of the 64 compliance-gaining strategies described by Kellerman and Cole.
