Not every person is hypnotizable to the same degree; some aren’t hypnotizable at all. “Hypnotizability … is modestly correlated with absorption, a personality construct reflecting a disposition to enter states of narrowed or expanded attention and a blurring of boundaries between oneself and the object of perception,” writes John F. Kihlstrom, a psychologist at the University of California, Berkeley, in a 2013 paper in Cortex. “Absorption, in turn, is related to ‘openness to experience,’ one of the ‘Big Five” dimensions of personality.”
Once the person is in the trance state, and is in a safe seated position, you can use the power of suggestion on your hypnotized subject. For example, you can tell them that when you count to three that they will open their eyes but that they will not remember their name. Then count to three and tell them to open their eyes. When their eyes are open, ask them to tell you their name. They will be amazed that they can't remember their own name.
Following the French committee's findings, Dugald Stewart, an influential academic philosopher of the "Scottish School of Common Sense", encouraged physicians in his Elements of the Philosophy of the Human Mind (1818) to salvage elements of Mesmerism by replacing the supernatural theory of "animal magnetism" with a new interpretation based upon "common sense" laws of physiology and psychology. Braid quotes the following passage from Stewart:
Most relaxation techniques require daily practice to be effective. A variety of formats for teaching relaxation and meditation exist, including classes as well as individual sessions. Relaxation can be taught in 1 session by conducting and audio taping a relaxation session. Using the audio tape, patients can then practice the techniques daily at home. Methods such as progressive muscle relaxation are easy to learn; yoga, tai chi, and meditation can take years to master completely.
“With hypnosis, you capture people’s attention. … You get people to turn to a more passive state of attention and to stop judging everything. To just let it happen,” Patterson said. “And when you do this, the amazing thing is that it’s as if you’re talking directly to the part of the brain that’s monitoring the reactions.” In his work, he ties suggestions of comfort to the daily practice of caring for burn wounds. “In burn care you know they’re going to pull off the bandages and then they’re going to start washing the wounds,” he explains. “The message is that when your wounds are washed, that will be the reminder of how comfortable you are.” The patient will often look like they’re asleep. “But if you ask them, ‘If you can still hear me, feel your head nod,’ almost always you’ll get that head nod,” he said. He’s seen this work for decades, but is so grateful for the recent advent of brain-imaging studies. They serve as evidence he can hold up to skeptics: See? Do you believe me now?
"How long will I spend in therapy?", is like asking, "How long is a piece of string?" Everyone is different and everyone's individual needs and circumstances vary. There is no definitive answer. However, while some talking therapies can require commitments of a year or more, hypnotherapy tends to be a much faster solution. The average length of time I spend with a client is around 4-6 weekly sessions, to create sustainable changes which some have been trying to implement for years.
In hypnosis, patients typically see practitioners by themselves for a course of hourly or half-hourly treatments. Some general practitioners and other medical specialists use hypnosis as part of their regular clinical work and follow a longer initial consultation with standard 10- to 15-minute appointments. Patients can be given a post-hypnotic suggestion that enables them to induce self-hypnosis after the treatment course is completed. Some practitioners undertake group hypnosis, treating up to a dozen patients at a time—for example, teaching self-hypnosis to prenatal groups as preparation for labor.
In 2007, a meta-analysis from the Cochrane Collaboration found that the therapeutic effect of hypnotherapy was "superior to that of a waiting list control or usual medical management, for abdominal pain and composite primary IBS symptoms, in the short term in patients who fail standard medical therapy", with no harmful side-effects. However the authors noted that the quality of data available was inadequate to draw any firm conclusions.
Many of the clucking chicken images are the result of hypnosis’s forefather, Franz Anton Mesmer (1734-1815). Mesmer believed that there was an invisible force, a cosmic energy, that could be harnessed by one person to influence another person’s behavior. While his theory was wrong, the techniques he used were effective. These techniques were picked up on and developed over the coming years for therapeutic and medical purposes. Sigmund Freud, for instance, used hypnosis techniques. In the mid-1900s, hypnotherapy as we know it evolved. Milton Erickson (1901-1980) pioneered “indirect hypnosis,” during which therapists work with individual patients to shift their perceptions of themselves and their issues.
Research into hypnosis in military applications is further verified by the Project 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 expert, Dr Peter Marshall, former Principal of the London School of Hypnotherapy and Psychotherapy Ltd. and author of A Handbook of Hypnotherapy, devised the Trance Theory of Mental Illness, which provides that people suffering from depression, or certain other kinds of neurosis, are already living in a trance and so the hypnotherapist does not need to induce them, but rather to make them understand this and help lead them out of it.
