Concept
Desensitization (psychology)
Summary
In psychology, Desensitization is a treatment or process that diminishes emotional responsiveness to a negative, aversive, or positive stimulus after repeated exposure. Desensitization can also occur when an emotional response is repeatedly evoked in situations where the action tendency associated with the emotion proves irrelevant or unnecessary. The process of desensitization was developed by psychologist Mary Cover Jones and is primarily used to assist individuals in unlearning phobias and anxieties. Desensitization is a psychological process where a response is repeatedly elicited in circumstances where the emotion's propensity for action is irrelevant. Joseph Wolpe (1958) developed a method of a hierarchal list of anxiety-evoking stimuli in order of intensity, which allows individuals to undergo adaptation. Although medication is available for individuals with anxiety, fear, or phobias, empirical evidence supports desensitization with high rates of cure, particularly in clients with depression or schizophrenia. Wolpe's "reciprocal inhibition" desensitization process is based on well-known psychology theories such as Hull's "drive-reduction" theory and Sherrington's concept of "reciprocal inhibition." Individuals are gradually exposed to anxiety triggers while using relaxation techniques to reduce anxiety. It is an effective treatment for anxiety disorders.
The hierarchical list is constructed between client and therapist in rank ordered series of steps from the least disturbing to the most disturbing fears or phobias. A list of escalating exposure scenarios is created by the therapist and the patient for acrophobia.The patient progresses from using a low step ladder to standing and taking the first step. The scenes are arranged in a commonly used version of this treatment in order of increasing arousal. Secondly, the client is taught techniques that produce deep relaxation. This is repeated until the element of the hierarchy no longer causes anxiety or fear, at which point the next scene is shown.
