Hypnosis Hypnosis is a systematic procedure that typically produces a heightened state of suggestibility. History of Hypnosis Mesmerism - Credit for the popularity of hypnosis goes to Franz Anton Mesmer, a physician, who mistakenly thought he discovered “animal magnetism.” Some of his patients experienced a trancelike state and felt better upon waking up. In 1841 Scottish surgeon James Braid witnessed a demonstration of mesmerism and began to develop his own technique. Braid held a bright object in front of patients’ eyes while also making verbal suggestions. He argued mesmerism was a state of “nervous sleep” produced by concentrated attention. He renamed it hypnosis after Hypnos, the Greek god of sleep. Used in the U.S. by Benjamin Rush (Father of America Psychiatry) in the mid 1800’s The famous neurologist Charcot taught hypnosis to Freud in 1885 Freud popularized hypnosis as part of psychoanalytic therapy Now an established field and used for many purposes Hypnotic State Hypnosis is not like a sleep state Very relaxed waking state Suggestible state Focused attention Four Steps in Hypnosis Distractions are minimized Told to concentrate on something specific Told what to expect Suggest events or feelings to occur Hypnotic induction is the process by which one person leads another into hypnosis. Not necessary to swing a watch in front of the eyes or say “you are feeling sleepy”! Moss (1965) reported being able to sometimes induce a trance simply by saying “Please sit in that chair and go into hypnosis”! The goal of most induction procedures is to relax the subject and increase his or her attention Measured by hypnotic susceptibility scales Sample test items from the Stanford Hypnotic Susceptibility Scale, Form C Hypnotic Susceptibility Hilgard (1977) 10% of subjects will be completely nonresponsive, 10% will pass all or nearly all items, and the rest will fall in between. Hypnotic Susceptibility People who are imaginative and prone to fantasy are often very hypnotizable. But people who lack these traits can also be hypnotized. Susceptibility can be enhanced by increasing people’s expectations (Spanos et al., 1991; Vickery & Kirsch, 1991). If you are willing to be hypnotized, chances are good that you could be. Hypnosis depends more on the efforts and abilities of the hypnotized person than the skills of the hypnotist. Uses of Hypnosis Hypnosis is being used in a variety of medical and counseling situations Pain relief - very effective Dentistry, childbirth, even surgery Psychotherapy – many applications work o less effective for breaking habits like overeating and smoking Memory enhancement – Not very effective Posthypnotic suggestibility – a subject is given instructions under hypnosis and follows them after returning to a non-hypnotized state. Posthypnotic amnesia – the subject is instructed to not remember any of the suggested behavior after leaving the hypnotic state. Effects of Hypnosis Many abilities have been tested during hypnosis, leading to the following conclusions: Superhuman acts of strength: hypnosis has no more effect on physical strength than instructions that encourage a person to make his or her best effort. Memory: there is some evidence that hypnosis can enhance memory. However, it frequently increases the number of false memories, as well. For this reason, many states now bar people who have been hypnotized from testifying in court. Sensory Changes: Hypnotic suggestions concerning sensations are among the most effective. Is Hypnosis an Altered State of Consciousness? Social Cognitive or Influence Theory: Hypnotic subjects may simply be imaginative actors playing a social role. Divided Consciousness Theory: Hypnosis is a special state of dissociated (divided) consciousness (Hilgard, 1986, 1992). Summary Hypnosis produces an increased receptiveness to suggestions. Hypnotized people subjectively experience their actions to be involuntary. Dissociation theories attribute this to divided streams of consciousness. Social Cognitive theories attribute this to subject’s expectation as to what effect hypnosis will have on them.
