Exposure therapy is used to treat excessive fears, which are central to many anxiety disorders. During exposure therapy, the person is presented with a fear-evoking stimulus in a controlled fashion, until the fear diminishes. Treatment is collaborative, with the patient and therapist working together to decide how and when exposure will take place. Exposure duration depends on many factors, including the type of feared stimuli and the severity of the person's fears. Typically, an exposure session lasts 40–90 minutes, and sessions are repeated until the fear is substantially reduced or eliminated. Sessions may be either therapist-assisted or completed by the patient as homework assignments. In order to ensure that exposure is optimally effective, the patient is exposed to fear-evoking stimuli in a variety of different contexts to promote the generalization of therapeutic effects (Bouton, 2002).
