Phobias are highly susceptible to treatments based on conditioning. Most other disorders are not as susceptible to treatment. Two basic types of treatment are known as systematic desensitization and flooding. Systematic desensitization is basically showing something to the person with the phobia that brings positive emotion while having that phobia that creates the fear in the background at a distance. Each time this occurs the item that creates the fear is moved closer and closer. This is called a gradual conditioning procedure which eventually eliminates the phobia. Systematic desensitization pairs relaxation with a fear. Flooding therapy is a treatment that has the phobia being exposed for a long amount of time which gives the greatest amount of time that the phobia needs to be eliminated.
