Aversion therapy is one of the more classical behavioral therapies and is somewhat similar to a punitive measure, that is, the patient is made to confront what he or she dislikes, resents, and hates, thus reducing the frequency of the bad behavior. The opposite of this is rewarding behavior, when the good behavior is expected to occur more frequently, give the patient some reward, such as giving some candy, tokens, these are all possible. If the patient is directly given what the patient is averse to, such as phobic patients, especially the fear of high or certain animals, directly expose it to a particularly high scene, or full of the animal scene feared, may not be accepted at once, and even particularly fear, fear, panic, the most serious time will have a feeling of near death, so it is very dangerous. The next best thing is to use a more systematic, safer, step-by-step approach, that is, the patient’s aversion to some of these scenes, divided into different levels of exposure, so that patients slowly accept their own fear and anxiety, so also known as systematic desensitization therapy. Whether it is aversion therapy or systematic desensitization therapy, it must be done according to the actual situation of the patient, and it is best to do it under the guidance of professional counselors and psychiatrists.
