Hypnosis

Hypnosis is a psychological state whose existence and effects are strongly debated. Some believe that it is a state under which the subject's mind becomes so suggestible that the hypnotist, the one who induces the state, can establish communication with the subconscious mind of the subject and command behavior that the subject would not choose to perform in a conscious state (even behavior to be performed after the subject has left the hypnotic state, through post-hypnotic suggestion,) or even behavior the subject would be incapable of in a conscious state, such as not feeling pain, manifesting skin blisters as if the subject had been burned, or recalling things the subject's conscious memory does not retain. However, there is strong dispute and skepticism about what behavior and effects hypnosis can induce; some believe that the state does not actually exist, and that all effects of 'hypnotism' that have been observed are in actuality a combination of subjects' expectations (based on their beliefs of hypnotism's effects) and their desire to please the hypnotist (see Hawthorne Effect).

Notable organisations

• The American Society of Clinical Hypnosis http://www.asch.net/ is an organization that "promotes greater acceptance of hypnosis as a clinical tool with broad applications". Hypnosis is applied to a great range of both physical and psychological ailments, rather than being restricted to purely psychological phenomena. The society was founded by Milton Erickson, a doctor who attempted to put hypnosis on a firm therapeutic backing in the 1950s.
• The American Psychological Association's Divison 30, the Division of Psychological Hypnosis http://www.apa.org/divisions/div30/, "brings together psychologists and other professionals interested in scientific and applied hypnosis".
