Flooding, sometimes referred to as in vivo exposure therapy, is a form of behavior therapy and desensitization – or exposure therapy – based on the principles of respondent conditioning. As a psychotherapeutic technique, it is used to treat phobia and anxiety disorders including post-traumatic stress disorder .
Desensitization is commonly used with simple phobias like insect phobia. [23] [24] In addition, desensitization therapy is a useful tool in training domesticated dogs. [25] Systematic desensitization used in conjunction with counter-conditioning was shown to reduce problem behaviours in dogs, such as vocalization and property destruction. [25]
Systematic desensitization, (relaxation training paired with graded exposure therapy), is a behavior therapy developed by the psychiatrist Joseph Wolpe. It is used when a phobia or anxiety disorder is maintained by classical conditioning .
Since the 1950s, several sorts of exposure therapy have been developed, including systematic desensitization, flooding, implosive therapy, prolonged exposure therapy, in vivo exposure therapy, and imaginal exposure therapy. [22] Exposure and response prevention (ERP) traces its roots back to the work of psychologist Vic Meyer in the 1960s.
An abbreviated example of an exposure hierarchy is pictured in Image 1. Image 1: Exposure hierarchy example for treating public speaking fears. When exposure to an item at the bottom of the hierarchy leads to moderately reduced distress or increased tolerance, a client progresses up the hierarchy to more and more difficult exposures.
In medicine, desensitization is a method to reduce or eliminate an organism's negative reaction to a substance or stimulus. In pharmacology , drug desensitization refers to two related concepts. First, desensitization may be equivalent to drug tolerance and refers to subjects' reactions (positive or negative) to a drug reducing following its ...
Homologous desensitization also occurs with cytokine and other types of receptors, such as those of the epidermal growth factor receptor type, but in these cases desensitization is mediated by other types of receptor kinases. [2] Homologous desensitization serves to limit or restrain a cell's responses to stimuli.
Systematic desensitization is a process in which people seeking help slowly become accustomed to their phobia, and ultimately overcome it. Traditional systematic desensitization involves a person being exposed to the object they are afraid of over time so that the fear and discomfort do not become overwhelming.
