Hypnosis is a mental state (according to "state theory") or imaginative role-enactment (according to "non-state theory"). It is usually induced by a procedure known as a hypnotic induction, which is commonly composed of a long series of preliminary instructions and suggestions. Hypnotic suggestions may be delivered by a hypnotist in the presence of the subject, or may be self-administered ("self-suggestion" or "autosuggestion"). The use of hypnotism for therapeutic purposes is referred to as "hypnotherapy", while its use as a form of entertainment for an audience is known as "stage hypnosis".
The words hypnosis and hypnotism both derive from the term neuro-hypnotism (nervous sleep) coined by the Scottish surgeon James Braid around 1841. Braid based his practice on that developed by Franz Mesmer and his followers ("Mesmerism" or "animal magnetism"), but differed in his theory as to how the procedure worked.
Contrary to a popular misconception – that hypnosis is a form of unconsciousness resembling sleep – contemporary research suggests that hypnotic subjects are fully awake and are focusing attention, with a corresponding decrease in their peripheral awareness. Subjects also show an increased response to suggestions. In the first book on the subject, Neurypnology (1843), Braid described "hypnotism" as a state of physical relaxation accompanied and induced by mental concentration ("abstraction").
It could be said that hypnotic suggestion is explicitly intended to make use of the placebo effect. For example, in 1994, Irving Kirsch proposed a definition of hypnosis as a "nondeceptive mega-placebo," i. e., a method which openly makes use of suggestion and employs methods to amplify its effects.
James Randi, a professional magician and skeptic, provides a definition of hypnosis as "a mutual agreement of the operator and the subject that the subject will cooperate in following suggestions".
Braid elaborated upon this brief definition in a later work:
Braid therefore defined hypnotism as a state of mental concentration which often led to a form of progressive relaxation termed "nervous sleep". Later, in his The Physiology of Fascination (1855), Braid conceded that his original terminology was misleading, and argued that the term "hypnotism" or "nervous sleep" should be reserved for the minority (10%) of subjects who exhibited amnesia, substituting the term "monoideism", meaning concentration upon a single idea, as a description for the more alert state experienced by the others.
A new definition of hypnosis, derived from academic psychology, was provided in 2005, when the Society for Psychological Hypnosis, Division 30 of the American Psychological Association (APA), published the following formal definition:
I define hypnotism as the induction of a peculiar psychical [i.e., mental] condition which increases the susceptibility to suggestion. Often, it is true, the [hypnotic] sleep that may be induced facilitates suggestion, but it is not the necessary preliminary. It is suggestion that rules hypnotism. (Hypnosis & Suggestion, 1884: 15)
Bernheim's conception of the primacy of verbal suggestion in hypnotism dominated the subject throughout the twentieth century, leading some authorities to declare him the father of modern hypnotism (Weitzenhoffer, 2000).
Contemporary hypnotism makes use of a wide variety of different forms of suggestion including: direct verbal suggestions, "indirect" verbal suggestions such as requests or insinuations, metaphors and other rhetorical figures of speech, and non-verbal suggestion in the form of mental imagery, voice tonality, and physical manipulation. A distinction is commonly made between suggestions delivered "permissively" or in a more "authoritarian" manner. As Harvard hypnotherapist Deirdre Barrett describes in the book Tales from a Hypnotherapist’s Couch, most modern research suggestions are designed to bring about immediate responses—an arm rises immediately, whereas hypnotheraputic suggestions are usually post-hypnotic ones are intended to trigger responses affecting behavior for periods ranging from days to a lifetime in duration. The hypnotheraputic ones are often repeated in multiple sessions before they achieve peak effectiveness.
Whereas the older "depth scales" tried to infer the level of "hypnotic trance" based upon supposed observable signs, such as spontaneous amnesia, most subsequent scales measure the degree of observed or self-evaluated responsiveness to specific suggestion tests, such as direct suggestions of arm rigidity (catalepsy). The Stanford, Harvard, HIP, and most other susceptibility scales convert numbers into an assessment of a person's susceptibility as 'high', 'medium', or 'low'. Approximately 80% of the population are medium, 10% are high and 10% are low. There is some controversy as to whether this is distributed on a “normal” bell-shaped curve or whether it is bi-modal with a small “blip” of people at the high end. Hypnotizability Scores are highly stable over a person’s lifetime. Research by Deirdre Barrett has found that there are two distinct types of highly susceptible subjects which she terms fantasizers and dissociaters. Fantasizers score high on absorption scales, find it easy to block out real-world stimuli without hypnosis, spend much time daydreaming, report imaginary companions as a child and grew up with parents who encouraged imaginary play. Dissociaters often have a history of childhood abuse or other trauma, learned to escape into numbness, and to forget unpleasant events. Their association to “daydreaming” was often going blank rather than vividly recalled fantasies. Both score equally high on formal scales of hypnotic susceptibility.
Last May [1843], a gentleman residing in Edinburgh, personally unknown to me, who had long resided in India, favored me with a letter expressing his approbation of the views which I had published on the nature and causes of hypnotic and mesmeric phenomena. In corroboration of my views, he referred to what he had previously witnessed in oriental regions, and recommended me to look into the “Dabistan,” a book lately published, for additional proof to the same effect. On much recommendation I immediately sent for a copy of the “Dabistan”, in which I found many statements corroborative of the fact, that the eastern saints are all self-hypnotisers, adopting means essentially the same as those which I had recommended for similar purposes.
Although he rejected the transcendental/metaphysical interpretation given to these phenomena outright, Braid accepted that these accounts of Oriental practices supported his view that the effects of hypnotism could be produced in solitude, without the presence of any other person (as he had already proved to his own satisfaction with the experiments he had conducted in November 1841); and he saw correlations between many of the "metaphysical" Oriental practices and his own "rational" neuro-hypnotism, and totally rejected all of the fluid theories and magnetic practices of the mesmerists. As he later wrote:
In as much as patients can throw themselves into the nervous sleep, and manifest all the usual phenomena of Mesmerism, through their own unaided efforts, as I have so repeatedly proved by causing them to maintain a steady fixed gaze at any point, concentrating their whole mental energies on the idea of the object looked at; or that the same may arise by the patient looking at the point of his own finger, or as the Magi of Persia and Yogi of India have practised for the last 2,400 years, for religious purposes, throwing themselves into their ecstatic trances by each maintaining a steady fixed gaze at the tip of his own nose; it is obvious that there is no need for an exoteric influence to produce the phenomena of Mesmerism. […] The great object in all these processes is to induce a habit of abstraction or concentration of attention, in which the subject is entirely absorbed with one idea, or train of ideas, whilst he is unconscious of, or indifferently conscious to, every other object, purpose, or action.
In 1784, at the request of King Louis XVI, a series of French scientific committees, one of which included the American ambassador to France, Benjamin Franklin, scrutinized Mesmer's theories. They also investigated the practices of a disaffected student of Mesmer, one Charles d'Eslon (1750–1786), and despite the fact that they accepted that Mesmer's results were valid, their placebo-controlled experiments following d'Eslon's practices convinced them that Mesmerism's were most likely due to belief and imagination rather than to any sort of invisible energy ("animal magnetism") transmitted from the body of the Mesmerist.
It appears to me, that the general conclusions established by Mesmer’s practice, with respect to the physical effects of the principle of imagination [...] are incomparably more curious than if he had actually demonstrated the existence of his boasted science [of "animal magnetism"]: nor can I see any good reason why a physician, who admits the efficacy of the moral [i.e., psychological] agents employed by Mesmer, should, in the exercise of his profession, scruple to copy whatever processes are necessary for subjecting them to his command, any more than that he should hesitate about employing a new physical agent, such as electricity or galvanism.
In Braid's day, the Scottish School of Common Sense provided the dominant theories of academic psychology and Braid refers to other philosophers within this tradition throughout his writings. Braid therefore revised the theory and practice of Mesmerism and developed his own method of "hypnotism" as a more rational and "common sense" alternative.
It may here be requisite for me to explain, that by the term Hypnotism, or Nervous Sleep, which frequently occurs in the following pages, I mean a peculiar condition of the nervous system, into which it may be thrown by artificial contrivance, and which differs, in several respects, from common sleep or the waking condition. I do not allege that this condition is induced through the transmission of a magnetic or occult influence from my body into that of my patients; nor do I profess, by my processes, to produce the higher [i.e., supernatural] phenomena of the Mesmerists. My pretensions are of a much more humble character, and are all consistent with generally admitted principles in physiological and psychological science. Hypnotism might therefore not inaptly be designated, Rational Mesmerism, in contra-distinction to the Transcendental Mesmerism of the Mesmerists.
Despite briefly toying with the name "rational Mesmerism", Braid ultimately emphasised his approach's uniqueness, carrying out informal experiments throughout his career to refute the arguments invoking supernatural practices, and demonstrate instead the role of ordinary physiological and psychological processes such as suggestion and focused attention in producing the observed effects.
Braid worked very closely with his friend and ally the eminent physiologist Professor William Benjamin Carpenter, an early neuro-psychologist, who introduced the "ideo-motor reflex" theory of suggestion. Carpenter had observed examples of expectation and imagination apparently influencing involuntarily muscle movement. A classic example of the ideo-motor principle in action is the so-called "Chevreul pendulum" (named after Michel Eugène Chevreul). Chevreul claimed that divinatory pendulae were made to swing by unconscious muscle movements, brought about by appropriate concentration alone.
Braid soon assimilated Carpenter's observations into his own theory, realising that the effect of focusing attention was to enhance the ideo-motor reflex response. Braid extended Carpenter's theory to encompass the influence of the mind upon the body more generally, beyond the muscular system, and therefore referred to the "ideo-dynamic" response and coined the term "psycho-physiology" to refer to the study of general mind/body interaction.
In his later works, Braid reserved the term "hypnotism" for cases in which subjects entered a state of amnesia resembling sleep. For the rest, he spoke of a "mono-ideodynamic" principle to emphasise that the eye-fixation induction technique worked by narrowing the subject's attention to a single idea or train of thought ("monoideism") which amplified the effect of the consequent "dominant idea" upon the subject's body by means of the ideo-dynamic principle.
Azam's enthusiasm for hypnotism influenced Ambroise-Auguste Liébeault, a country doctor. Hippolyte Bernheim discovered Liébeault's enormously popular group hypnotherapy clinic and subsequently became an influential hypnotist. The study of hypnotism subsequently revolved around the fierce debate between Jean-Martin Charcot and Hippolyte Bernheim, the two most influential figures in late 19th century hypnotism.
Charcot operated a clinic at the Pitié-Salpêtrière Hospital (thus, also known as the "Paris School" or the "Salpêtrière School"), while Bernheim had a clinic in Nancy (also known as the "Nancy School"). Charcot, influenced more by the Mesmerists, argued that hypnotism was an abnormal state of nervous functioning found only in certain hysterical women. He claimed that it manifested in a series of physical reactions which could be divided into distinct stages. Bernheim argued that anyone could be hypnotised, that it was an extension of normal psychological functioning, and that its effects were due to suggestion. After decades of debate, Bernheim's view dominated. Charcot's theory is now just a historical curiosity.
Initially, Freud was an enthusiastic proponent of hypnotherapy, and soon began to emphasise hypnotic regression and ab reaction (catharsis) as therapeutic methods. He wrote a favorable encyclopedia article on hypnotism, translated one of Bernheim's works into German, and published an influential series of case studies with his colleague Joseph Breuer entitled Studies on Hysteria (1895). This became the founding text of the subsequent tradition known as "hypno-analysis" or "regression hypnotherapy."
However, Freud gradually abandoned hypnotism in favour of psychoanalysis, emphasizing free association and interpretation of the unconscious. Struggling with the great expense of time that psychoanalysis required, Freud later suggested that it might be combined with hypnotic suggestion to hasten the outcome of treatment,
It is very probable, too, that the application of our therapy to numbers will compel us to alloy the pure gold of analysis plentifully with the copper of direct [hypnotic] suggestion.
However only a handful of Freud's followers were sufficiently qualified in hypnosis to attempt the synthesis. Their work had a limited influence on the hypno-therapeutic approaches now known variously as "hypnotic regression", "hypnotic progression", and "hypnoanalysis".
Erickson had no hesitation in presenting any suggested effect as being "hypnosis", whether or not the subject was in a hypnotic state. In fact, he was not hesitant in passing off behaviour that was dubiously hypnotic as being hypnotic.
At the outset of cognitive-behavioural therapy during the 1950s, hypnosis was used by early behaviour therapists such as Joseph Wolpe and also by early cognitive therapists such as Albert Ellis. Barber, Spanos & Chaves introduced the term "cognitive-behavioural" to describe their "nonstate" theory of hypnosis in Hypnotism: Imagination & Human Potentialities (1974). Indeed, the earliest theories and practices of hypnotism, even those of Braid, resemble the cognitive-behavioural orientation in some respects.
Modern hypnotherapy has been used in a variety of forms, such as regression hypnotherapy (or "hypnoanalysis") and Ericksonian hypnotherapy.
Hypnosis has been studied clinically with varying success. Applications include: pain management weight loss skin disease
Self-hypnosis is popularly used to quit smoking and reduce stress, while stage hypnosis can persuade people to perform unusual public feats.
The evidence for hypnosis as an efficacious treatment of IBS was encouraging. Two of three studies that investigated the use of hypnosis for IBS were well designed and showed a clear effect for the hypnotic treatment of IBS.
Hypnosis for IBS has received moderate support in the National Institute for Health and Clinical Excellence guidance published for UK health services. It has been used as an aid or alternative to chemical anesthesia, and it has been studied as a way to soothe skin ailments.
In one study conducted at the Frenchay Hospital thirty-three patients with IBS were given four separate sessions of hypnosis over the course of seven weeks, each session lasting 40 minutes. Of the thirty-three patients, twenty reported an improvement in their symptoms while eleven were shown to be cleared of all symptoms. However some skeptics have claimed this sample size too small to be a meaningful result.
A number of studies show that hypnosis can reduce the pain experienced during burn-wound debridement, bone marrow aspirations, and childbirth. The International Journal of Clinical and Experimental Hypnosis found that hypnosis relieved the pain of 75% of 933 subjects participating in 27 different experiments.
In 1996, the National Institutes of Health declared hypnosis effective in reducing pain from cancer and other chronic conditions. For example, research done at the Mount Sinai School of Medicine studied two patient groups facing breast cancer surgery. The group that received hypnosis reported less pain, nausea, and anxiety post-surgery. The average hypnosis patient reduced treatment costs by an average $772.00.
The American Psychological Association published a study comparing the effects of hypnosis, ordinary suggestion and placebo in reducing pain. The study found that highly suggestible individuals experienced a greater reduction in pain from hypnosis compared with placebo, whereas less suggestible subjects experienced no pain reduction from hypnosis when compared with placebo. Ordinary non-hypnotic suggestion also caused reduction in pain compared to placebo, but was able to reduce pain in a wider range of subjects (both high and low suggestible) than hypnosis. The results showed that it is primarily the subjects responsiveness to suggestion, whether within the context of hypnosis or not, that is the main determinant of causing reduction in pain.
Treating skin diseases with hypnosis (hypnodermatology) has performed well in treating warts, psoriasis, and atopic dermatitis.
Hypnosis may be useful as an adjunct therapy for weight loss. A 1996 meta-analysis studying hypnosis combined with cognitive-behavioural therapy found that people using both treatments lost more weight than people using CBT alone.
The use of hypnosis in intelligence would present certain technical problems not encountered in the clinic or laboratory. To obtain compliance from a resistant source, for example, it would be necessary to hypnotise the source under essentially hostile circumstances. There is no good evidence, clinical or experimental, that this can be done.
Furthermore, the document states that:
It would be difficult to find an area of scientific interest more beset by divided professional opinion and contradictory experimental evidence…No one can say whether hypnosis is a qualitatively unique state with some physiological and conditioned response components or only a form of suggestion induced by high motivation and a positive relationship between hypnotist and subject…T.X. Barber has produced “hypnotic deafness” and “hypnotic blindness”, analgesia and other responses seen in hypnosis—all without hypnotizing anyone…Orne has shown that unhypnotized persons can be motivated to equal and surpass the supposed superhuman physical feats seen in hypnosis.
The study concludes:
It is probably significant that in the long history of hypnosis, where the potential application to intelligence has always been known, there are no reliable accounts of its effective use by an intelligence service.
Research into hypnosis in military applications is further verified by the MKULTRA experiments, also conducted by the CIA. According to Congressional testimony, the CIA experimented with utilizing LSD and hypnosis for mind control. Many of these programs were done domestically and on participants who were not informed of the study's purposes or that they would be given drugs.
Hypnotherapy is the use of hypnosis in psychotherapy. It is used by licensed physicians, psychologists, and others. Physicians and psychiatrists may use hypnosis to treat depression, anxiety, eating disorders, sleep disorders, compulsive gaming, and posttraumatic stress.
Certified hypnotherapists who are not physicians or psychologists often treat smoking and weight management. (Success rates vary: a meta-study researching hypnosis as a quit-smoking tool found it had a 20 to 30 percent success rate, similar to other quit-smoking methods, while a 2007 study of patients hospitalised for cardiac and pulmonary ailments found that smokers who used hypnosis to quit smoking doubled their chances of success.)
In a January 2001 article in Psychology Today Harvard psychologist Deirdre Barrett wrote
A hypnotic trance is not therapeutic in and of itself, but specific suggestions and images fed to clients in a trance can profoundly alter their behavior. As they rehearse the new ways they want to think and feel, they lay the groundwork for changes in their future actions...and she described specific ways this is operationalized for habit change and amelioration of phobias. In her 1998 book of hypnotherapy case studies, she reviews the clinical research on hypnosis with dissociative disorders, smoking cessation, and insomnia and describes successful treatments of these complaints.
In a July 2001 article for Scientific American titled "The Truth and the Hype of Hypnosis", Michael Nash wrote:
...using hypnosis, scientists have temporarily created hallucinations, compulsions, certain types of memory loss, false memories, and delusions in the laboratory so that these phenomena can be studied in a controlled environment. Past life regression, meanwhile, is often viewed with skepticism.
Self-hypnosis
Self-hypnosis happens when a person hypnotises himself or herself, commonly involving the use of autosuggestion. The technique is often used to increase motivation for a diet, quit smoking, or reduce stress. People who practice self-hypnosis sometimes require assistance; some people use devices known as mind machines to assist in the process, while others use hypnotic recordings.Self-hypnosis is claimed to help with stage fright, relaxation, and physical well-being.
Stage hypnosis
Stage hypnosis is a form of entertainment, traditionally employed in a club or theatre before an audience. Due to stage hypnotists' showmanship, many people believe that hypnosis is a form of mind control. Stage hypnotists typically attempt to hypnotise the entire audience and then select individuals who are "under" to come up on stage and perform embarrassing acts, while the audience watches. However, the effects of stage hypnosis are probably due to a combination of psychological factors, participant selection, suggestibility, physical manipulation, stagecraft, and trickery. The desire to be the centre of attention, having an excuse to violate their own fear suppressors and the pressure to please are thought to convince subjects to 'play along'. Books by stage hypnotists sometimes explicitly describe the use of deception in their acts, for example, Ormond McGill's New Encyclopedia of Stage Hypnosis describes an entire "fake hypnosis" act which depends upon the use of private whispers throughout.
[The hypnotist whispers off-microphone:] “We are going to have some good laughs on the audience and fool them… so when I tell you to do some funny things, do exactly as I secretly tell you. Okay? Swell.” (Then deliberately wink at the spectator in a friendly fashion.)Stage hypnosis traditionally employs two fundamental strategies: # Participant selection. Preliminary suggestion tests, such as asking the audience to clasp their hands and suggesting they cannot be separated, are usually used to select out the most suggestible and compliant subjects from the audience. By asking for volunteers to mount the stage, the performer also tends to select the most extroverted members of the audience. # Deception of the audience. Stage hypnotists are performers who traditionally, but not always, employ a variety of "sleight of hand" strategies to mislead their audience for dramatic effect.
The strategies of deception employed in traditional stage hypnosis can be categorised as follows: # Off-microphone whispers. The hypnotist lowers his microphone and whispers secret instructions to the participant on stage, outside of the audience's hearing. These may involve requests to "play along" or fake hypnotic responses. # Failure to challenge. The stage hypnotist pretends to challenge subjects to defy a suggestion, e.g., "You cannot stand up out of your chair because your backside is stuck down with glue." However, no specific cue is given to the participants to begin their effort ("Start trying now!"). This creates the illusion that a specific challenge has been issued and effort made to defy it. # Fake hypnosis tricks. Stage hypnosis literature contains a large repertoire of sleight of hand tricks, of the kind used by professional illusionists. None of these tricks requires any hypnosis or suggestion, depending on physical manipulation and audience deception. The most famous example of this type is the "human plank" trick, which involves making a subject's body become rigid (cataleptic) and suspending them horizontally between two chairs, at which point the hypnotist will often stand upon their chest for dramatic effect. This has nothing to do with hypnosis, but simply depends on the fact that when subjects are positioned in the correct way they can support more weight than the audience assumes.
Other uses
Hypnotism has also been used in forensics, sports, education, physical therapy and rehabilitation. Hypnotism has also been employed by artists for creative purposes most notably the surrealist circle of André Breton who employed hypnosis, automatic writing and sketches for creative purposes. Hypnotic methods have been used to re-experience drug states, and mystical experiences.Some people have drawn analogies between certain aspects of hypnotism and areas such as crowd psychology, religious hysteria, and ritual trances in preliterate tribal cultures.
Many famous sports figures like Tiger Woods have used hypnosis to gain an edge on their competition. This is accomplished by accessing an athlete's altered conscious state and incorporating a different way of processing information.
The state versus non-state debate
The central theoretical disagreement is known as the "state versus nonstate" debate. When Braid introduced the concept of hypnotism he equivocated over the nature of the "state", sometimes describing it as a specific sleep-like neurological state comparable to animal hibernation or yogic meditation, while at other times he emphasised that hypnotism encompassed a number of different stages or states which were an extension of ordinary psychological and physiological processes. Overall, Braid appears to have moved from a more "special state" understanding of hypnotism toward a more complex "nonstate" orientation.State theorists interpret the effects of hypnotism as primarily due to a specific, abnormal and uniform psychological or physiological state of some description, often referred to as "hypnotic trance" or an "altered state of consciousness." Nonstate theorists rejected the idea of hypnotic trance and interpret the effects of hypnotism as due to a combination of multiple task-specific factors derived from normal cognitive, behavioural and social psychology, such as social role-perception and favorable motivation (Sarbin), active imagination and positive cognitive set (Barber), response expectancy (Kirsch), and the active use of task-specific subjective strategies (Spanos). The personality psychologist Robert White is often cited as providing one of the first nonstate definitions of hypnosis in a 1941 article:
Hypnotic behaviour is meaningful, goal-directed striving, its most general goal being to behave like a hypnotised person as this is continuously defined by the operator and understood by the client.Put simply, it is often claimed that whereas the older "special state" interpretation emphasises the difference between hypnosis and ordinary psychological processes, the "nonstate" interpretation emphasises their similarity.
Comparisons between hypnotised and non-hypnotised subjects suggest that if a "hypnotic trance" does exist it only accounts for a small proportion of the effects attributed to hypnotic suggestion, most of which can be replicated without hypnotic induction.
Hyper-suggestibility
Braid can be taken to imply, in later writings, that hypnosis is largely a state of heightened suggestibility induced by expectation and focused attention. In particular, Hippolyte Bernheim became known as the leading proponent of the "suggestion theory" of hypnosis, at one point going so far as to declare that there is no hypnotic state, only heightened suggestibility. There is a general consensus that heightened suggestibility is an essential characteristic of hypnosis.
If a subject after submitting to the hypnotic procedure shows no genuine increase in susceptibility to any suggestions whatever, there seems no point in calling him hypnotised, regardless of how fully and readily he may respond to suggestions of lid-closure and other superficial sleeping behaviour.
Conditioned inhibition
Ivan Pavlov stated that hypnotic suggestion provided the best example of a conditioned reflex response in human beings, i.e., that responses to suggestions were learned associations triggered by the words used. Pavlov himself wrote:
Speech, on account of the whole preceding life of the adult, is connected up with all the internal and external stimuli which can reach the cortex, signaling all of them and replacing all of them, and therefore it can call forth all those reactions of the organism which are normally determined by the actual stimuli themselves. We can, therefore, regard ‘suggestion’ as the most simple form of a typical reflex in man.He also believed that hypnosis was a "partial sleep" meaning that a generalised inhibition of cortical functioning could be encouraged to spread throughout regions of the brain. He observed that the various degrees of hypnosis did not significantly differ physiologically from the waking state and hypnosis depended on insignificant changes of environmental stimuli. Pavlov also suggested that lower-brain-stem mechanisms were involved in hypnotic conditioning.
Pavlov's ideas combined with those of his rival Bekhterev and became the basis of hypnotic psychotherapy in the Soviet Union, as documented in the writings of his follower K.I. Platonov. Soviet theories of hypnotism subsequently influenced the writings of Western behaviourally-oriented hypnotherapists such as Andrew Salter.
Neuropsychology
Neurological imaging techniques provide no evidence of a neurological pattern that can be equated with a "hypnotic trance". Changes in brain activity have been found in some studies of highly responsive hypnotic subjects. These changes vary depending upon the type of suggestions being given. However, what these results indicate is unclear. They may indicate that suggestions genuinely produce changes in perception or experience that are not simply a result of imagination. However, in normal circumstances without hypnosis, the brain regions associated with motion detection are activated both when motion is seen and when motion is imagined, without any changes in the subjects' perception or experience. This may therefore indicate that highly suggestible hypnotic subjects are simply activating to a greater extent the areas of the brain used in imagination, without real perceptual changes.Another study has demonstrated that a color hallucination suggestion given to subjects in hypnosis activated color-processing regions of the occipital cortex. A 2004 review of research examining the EEG laboratory work in this area concludes:
The induction phase of hypnosis may also affect the activity in brain regions which control intention and process conflict. Anna Gosline claims:
Dissociation
Pierre Janet originally developed the idea of dissociation of consciousness from his work with hysterical patients. He believed that hypnosis was an example of dissociation, whereby areas of an individual's behavioural control separate from ordinary awareness. Hypnosis would remove some control from the conscious mind, and the individual would respond with autonomic, reflexive behaviour. Weitzenhoffer describes hypnosis via this theory as "dissociation of awareness from the majority of sensory and even strictly neural events taking place."
Neodissociation
Ernest Hilgard, who developed the "neodissociation" theory of hypnotism, hypothesised that hypnosis causes the subjects to divide their consciousness voluntarily. One part responds to the hypnotist while the other retains awareness of reality. Hilgard made subjects take an ice water bath. They said nothing about the water being cold or feeling pain. Hilgard then asked the subjects to lift their index finger if they felt pain and 70% of the subjects lifted their index finger. This showed that even though the subjects were listening to the suggestive hypnotist they still sensed the water's temperature.
Mind-dissociation
This theory was proposed by Y.D. Tsai in 1995 as part of his psychosomatic theory of dreams. Inside each brain, there is a program " I " (the conscious self) which is distributed over the conscious brain and coordinates mental functions (cortices), such as thinking, imagining, sensing, moving, reasoning … etc. "I" also supervises memory storage. Many bizarre states of consciousness are actually the results of dissociation of certain mental functions from "I".When a person is hypnotized, it might be that his/her imagination is dissociated and sends the imagined content back to the sensory cortex, resulting in dreams or hallucinations; or that some senses are dissociated, resulting in hypnotic anesthesia; or that motor function is dissociated, resulting in immobility; or that reason is dissociated and he/she obeys the hypnotist's orders; or that thought is dissociated and not controlled by reason, hence strives to straighten out his/her body between two chairs. A command can also be acted out long after the hypnosis session, as follows: The subject obeys the voice of reason in normal state, but when hypnotized, reason is replaced by the hypnotist's command to make decisions or beliefs, and will be very uneasy if he/she does not do things as decided or his/her belief is contradicted. Hypnotherapy is also based on this principle.
Social role-taking theory
The main theorist who pioneered the influential role-taking theory of hypnotism was Theodore Sarbin. Sarbin argued that hypnotic responses were motivated attempts to fulfill the socially-constructed roles of hypnotic subjects. This has led to the misconception that hypnotic subjects are simply "faking". However, Sarbin emphasised the difference between faking, in which there is little subjective identification with the role in question, and role-taking, in which the subject not only acts externally in accord with the role but also subjectively identifies with it to some degree, acting, thinking, and feeling "as if" they are hypnotised. Sarbin drew analogies between role-taking in hypnosis and role-taking in other areas such as method acting, mental illness, and shamanic possession, etc. This interpretation of hypnosis is particularly relevant to understanding stage hypnosis in which there is clearly strong peer pressure to comply with a socially-constructed role by performing accordingly on a theatrical stage.Hence, the social constructionism and role-taking theory of hypnosis suggests that individuals are enacting (as opposed to merely playing) a role and that really there is no such thing as a hypnotic trance. A socially-constructed relationship is built depending on how much rapport has been established between the "hypnotist" and the subject (see Hawthorne effect, Pygmalion effect, and placebo effect).
Psychologists such as Robert Baker and Graham Wagstaff claim that what we call hypnosis is actually a form of learned social behaviour, a complex hybrid of social compliance, relaxation, and suggestibility that can account for many esoteric behavioural manifestations.
Cognitive-behavioural theory
Barber, Spanos, & Chaves (1974) proposed a nonstate "cognitive-behavioural" theory of hypnosis, similar in some respects to Sarbin's social role-taking theory and building upon the earlier research of Barber. On this model, hypnosis is explained as an extension of ordinary psychological processes like imagination, relaxation, expectation, social compliance, etc. In particular, Barber argued that responses to hypnotic suggestions were mediated by a "positive cognitive set" consisting of positive expectations, attitudes, and motivation. Daniel Araoz subsequently coined the acronym "TEAM" to symbolise the subject's orientation to hypnosis in terms of "trust", "expectation", "attitude", and "motivation".Barber et al., noted that similar factors appeared to mediate the response both to hypnotism and to cognitive-behavioural therapy (CBT), in particular systematic desensitization. Hence, research and clinical practice inspired by their interpretation has led to growing interest in the relationship between hypnotherapy and CBT.
Information theory
An approach loosely based on Information theory uses a brain-as-computer model. In adaptive systems, feedback increases the signal-to-noise ratio, which may converge towards a steady state. Increasing the signal-to-noise ratio enables messages to be more clearly received. The hypnotist's object is to use techniques to reduce interference and increase the receptability of specific messages (suggestions).
Systems theory
Systems theory, in this context, may be regarded as an extension of Braid's original conceptualization of hypnosis as involving a process of enhancing or depressing nervous system activity. Systems theory considers the nervous system's organization into interacting subsystems. Hypnotic phenomena thus involve not only increased or decreased activity of particular subsystems, but also their interaction. A central phenomenon in this regard is that of feedback loops, which suggest a mechanism for creating hypnotic phenomena.

Richard Wayne Bandler (born February 24, 1950) is an American author and trainer in the fields of alternative psychology and of self-help. He is best known as the co-inventor (with John Grinder) of Neuro-linguistic programming (NLP), a collection of concepts and techniques intended to understand and change human behavior-patterns. He also developed other systems known as Design Human Engineering (DHE) and Neuro Hypnotic Repatterning (NHR).
While Bandler was a student at University of California, Santa Cruz he also led a Gestalt therapy group. John Grinder, a professor at the University, said to Bandler that he could explain almost all of the questions and comments Bandler made using transformational grammar, the topic in linguistics that Grinder specialized in. They developed a model for therapy and called it the meta-model. It became their first book, The Structure of Magic, Volume I (1975).
Bandler was Gregory Bateson's landlord. Bateson taught at UCSC, Kresge College as did Grinder, and had moved to a community on Alba Road near the Santa Cruz mountains community of Ben Lomond. He would have a profound influence on Bandler's future, introducing him and Grinder to Milton Erickson, the three of them together forming some of the foundational models for Neuro-linguistic programming. In 1975 Bandler then formed his own company, Meta Publications, and released Patterns of the Hypnotic Techniques of Milton H. Erickson Volume I (1975).
Bandler and Grinder went on to author The Structure of Magic Volume II (1976), Patterns of the Hypnotic Techniques of Milton H. Erickson Volume II (1977) and Changing With Families (1976) which was co-authored with Virginia Satir herself.
Bandler also modeled Israeli physicist and founder of the Feldenkrais school of body work, Moshe Feldenkrais, and later published his book "The Elusive Obvious". In many of his classes he has taught elements of this form of bodywork which he modeled.
Since that time Bandler's career has focused on developing and presenting NLP and related concepts as an author, publisher, public speaker and consultant. Audiences include individuals seeking life improvement and businesses using these concepts and techniques to improve sales.
By the end of 2000 some sort of rapprochement between Bandler and Grinder was achieved when the parties entered a release wherein they agreed, among other things, that "they are the co-creators and co-founders of the technology of Neuro-linguistic Programming. "Drs. Grinder and Bandler recognize the efforts and contributions of each other in the creation and initial development of NLP." In the same document, "Dr. John Grinder and Dr. Richard Bandler mutually agree to refrain from disparaging each other's efforts, in any fashion, concerning their respective involvement in the field of NeuroLinguistic Programming." ("Release" reproduced as Appendix A of Whispering in the Wind by Grinder and Bostic St Clair (2001)).
