Hypnosis has long been considered a valuable technique for recreating and then studying puzzling psychological phenomena. A classic example of this approach uses a technique known as posthypnotic amnesia (PHA) to model memory disorders such as functional amnesia, which involves a sudden memory loss typically due to some sort of psychological trauma (rather than to brain damage or disease). Hypnotists produce PHA by suggesting to a hypnotized person that after hypnosis he will forget particular things until he receives a “cancellation,” such as “Now you can remember everything.” PHA typically only happens when it is specifically suggested and it is much more likely to occur in those with high levels of hypnotic ability, or “high hypnotizable” people. Now a new study shows that this hypnotic state actually influences brain activity associated with memory.
Hypnosis -- or hypnotherapy -- uses guided relaxation, intense concentration, and focused attention to achieve a heightened state of awareness that is sometimes called a trance. The person's attention is so focused while in this state that anything going on around the person is temporarily blocked out or ignored. In this naturally occurring state, a person may focus his or her attention -- with the help of a trained therapist -- on specific thoughts or tasks.
But psychiatrists do understand the general characteristics of hypnosis, and they have some model of how it works. It is a trance state characterized by extreme suggestibility, relaxation and heightened imagination. It's not really like sleep, because the subject is alert the whole time. It is most often compared to daydreaming, or the feeling of "losing yourself" in a book or movie. You are fully conscious, but you tune out most of the stimuli around you. You focus intently on the subject at hand, to the near exclusion of any other thought.
The British Psychological Society commissioned a working group to survey the evidence and write a formal report on hypnotherapy in 2001. They found, “Enough studies have now accumulated to suggest that the inclusion of hypnotic procedures may be beneficial in the management and treatment of a wide range of conditions and problems encountered in the practice of medicine, psychiatry and psychotherapy.”
“I never expected how much transformation is possible with this work. This hypnotherapy training went far beyond my expectations. The incredible amount of wonderfully presented material and deep wisdom touched my heart on a very deep level. The combination of hypnosis and very profound and effective methods of processing is incredible. To see the profound changes in my classmates and myself is such a gift, I feel deep gratitude for that. To imagine how much positive change will occur in other people due to this work moves my heart.”
In 10th grade my school brought a celebrity hypnotist for an event. My friend signed me up without knowing and we were called up in front of the entire school. First he has us do an experiment with our hands and how we wouldn't be able to open them - then he choose 7 people and we got to be "hypnotized" for the rest of the event (15 mins or so). I got "picked on" the most for the stuff (forgetting my name, forgetting the number 6) were the one's i did alone. Others were (playing a violin, using your shoe as a phone). I remember actively playing along in order to put on a good show - and he choose us because we were willing to play along.
After hypnosis, participants’ memories were tested twice while the fMRI scanner recorded their brain activity. For Test 1, they were asked 40 questions about the content of the movie (for example, the actress knocked on her neighbor’s door on the way home) and 20 questions about the context in which they saw the movie (for instance, during the movie, the door to the study room was closed). These questions required a “yes” or “no” response. For Test 2, participants were asked the same 60 recognition questions, but first they heard the cue to cancel PHA. So Test 1 measured memory performance and brain activity while the PHA suggestion was in effect and Test 2 measured memory performance and brain activity after it was cancelled.
The Federal Dictionary of Occupational Titles describes the job of the hypnotherapist: "Induces hypnotic state in client to increase motivation or alter behavior patterns: Consults with client to determine nature of problem. Prepares client to enter hypnotic state by explaining how hypnosis works and what client will experience. Tests subject to determine degree of physical and emotional suggestibility. Induces hypnotic state in client, using individualized methods and techniques of hypnosis based on interpretation of test results and analysis of client's problem. May train client in self-hypnosis conditioning. GOE: 10.02.02 STRENGTH: S GED: R4 M3 L4 SVP: 7 DLU: 77"
