In the 1950's new ways of treatment were being sought. The emergence of drug therapy has revolutionized the treatment of ailments ranging from mild depression to manic schizophrenia.

Behavior therapy uses different approaches such as systematic desensitization and aversion therapy. The cognitive-behavioral approach attempts to modify a person's self statements to change his or her behavior.
