How to do Hypnosis, How Hypnosis works (Part 2)

Suggestion Box

In the last section, we examined the idea that hypnosis puts your conscious mind in the backseat, so you and the hypnotist can communicate directly with your subconscious. This theory has gained wide acceptance in the psychiatric community, mostly because it explains all the major characteristics of the hypnotic state so nicely.

Hypnotists say that subjects under hypnosis are a lot like little kids: playful and imaginative, fully embracing bizarre suggestions.

It provides an especially convincing explanation for the playfulness and uninhibitedness of hypnotic subjects. The conscious mind is the main inhibitive component in your makeup -- it's in charge of putting on the brakes -- while the subconscious mind is the seat of imagination and impulse. When your subconscious mind is in control, you feel much freer and may be more creative. Your conscious mind doesn't have to filter through everything.

Hypnotized people do such bizarre things so willingly, this theory holds, because the conscious mind is not filtering and relaying the information they take in. It seems like the hypnotist's suggestions are coming directly from the subconscious, rather than from another person. You react automatically to these impulses and suggestions, just as you would to your own thoughts. Of course, your subconscious mind does have a conscience, a survival instinct and its own ideas, so there are a lot of things it won't agree to.

The subconscious regulates your bodily sensations, such as taste, touch and sight, as well as your emotional feelings. When the access door is open, and the hypnotist can speak to your subconscious directly, he or she can trigger all these feelings, so you experience the taste of a chocolate milkshake, the satisfaction of contentment and any number of other feelings.

Additionally, the subconscious is the storehouse for all your memories. While under hypnosis, subjects may be able to access past events that they have completely forgotten. Psychiatrists may use hypnotism to bring up these memories so that a related personal problem can finally be resolved. Since the subject's mind is in such a suggestible state, it is also possible to create false memories. For this reason, psychiatrists must be extremely careful when exploring a hypnotic subject's past.

This theory of hypnosis is based mostly on logical reasoning, but there is some physiological evidence that supports it. In the next section, we'll look at some of the physical data researchers have gathered on hypnosis.

Waves and Hemispheres

In numerous studies, researchers have compared the physical "body signs" of hypnotic subjects with those of unhypnotized people. In most of these studies, the researchers found no significant physical change associated with the trance state of hypnosis. The subject's heart rate and respiration may slow down, but this is due to the relaxation involved in the hypnotism process, not the hypnotic state itself.

Do it yourself You don't necessarily need a highly-trained hypnotist to induce hypnosis. With the proper relaxation and focusing techniques, almost everyone can enter a hypnotic state themselves and make their own suggestions to the unconscious mind Some hypnotism experts hold that all hypnosis is self-hypnosis. Whether a trance state is brought on by a long, boring drive down the highway or by a skilled psychiatrist, the subject is always the one who initiates the trance. In this view, the hypnotist is only a guide who facilitates the process.

There does seem to be changed activity in the brain, however. The most notable data comes from electroencephalographs (EEGs), measurements of the electrical activity of the brain. Extensive EEG research has demonstrated that brains produce different brain waves, rhythms of electrical voltage, depending on their mental state. Deep sleep has a different rhythm than dreaming, for example, and full alertness has a different rhythm than relaxation.

In some studies, EEGs from subjects under hypnosis showed a boost in the lower frequency waves associated with dreaming and sleep, and a drop in the higher frequency waves associated with full wakefulness. Brain-wave information is not a definitive indicator of how the mind is operating, but this pattern does fit the hypothesis that the conscious mind backs off during hypnosis and the subconscious mind takes a more active role.

Researchers have also studied patterns in the brain's cerebral cortex that occur during hypnosis. In these studies, hypnotic subjects showed reduced activity in the left hemisphere of the cerebral cortex, while activity in the right hemisphere often increased. Neurologists believe that the left hemisphere of the cortex is the logical control center of the brain; it operates on deduction, reasoning and convention. The right hemisphere, in contrast, controls imagination and creativity. A decrease in left-hemisphere activity fits with the hypothesis that hypnosis subdues the conscious mind's inhibitory influence. Conversely, an increase in right-brain activity supports the idea that the creative, impulsive subconscious mind takes the reigns. This is by no means conclusive evidence, but it does lend credence to the idea that hypnotism opens up the subconscious mind.

Whether or not hypnosis is actually a physiological phenomenon, millions of people do practice hypnotism regularly, and millions of subjects report that it has worked on them. In the next section, we'll look at the most common methods of inducing a hypnotic trance.

You're Getting Sleepy

Hypnotists' methods vary, but they all depend on a few basic prerequisites:

• The subject must want to be hypnotized.
• The subject must believe he or she can be hypnotized.
• The subject must eventually feel comfortable and relaxed.

If these criteria are met, the hypnotist can guide the subject into a hypnotic trance using a variety of methods. The most common hypnotic techniques are:

• Fixed-gaze induction or eye fixation - This is the method you often see in movies, when the hypnotist waves a pocket watch in front of the subject.

  The basic idea is to get the subject to focus on an object so intently that he or she tunes out any other stimuli. As the subject focuses, the hypnotist talks to him or her in a low tone, lulling the subject into relaxation. This method was very popular in the early days of hypnotism, but it isn't used much today because it doesn't work on a large proportion of the population.

• Rapid - The idea of this method is to overload the mind with sudden, firm commands.

  If the commands are forceful, and the hypnotist is convincing enough, the subject will surrender his or her conscious control over the situation. This method works well for a stage hypnotist because the novel circumstance of being up in front of an audience puts subjects on edge, making them more susceptible to the hypnotist's commands.

• Progressive relaxation and imagery - This is the hypnosis method most commonly employed by psychiatrists.

  By speaking to the subject in a slow, soothing voice, the hypnotist gradually brings on complete relaxation and focus, easing the subject into full hypnosis. Typically, self-hypnosis training, as well as relaxation and meditation audio tapes, use the progressive relaxation method.

• Loss of balance - This method creates a loss of equilibrium using slow, rhythmic rocking.

  Parents have been putting babies to sleep with this method for thousands of years.

Before hypnotists bring a subject into a full trance, they generally test his or her willingness and capacity to be hypnotized. The typical testing method is to make several simple suggestions, such as "Relax your arms completely," and work up to suggestions that ask the subject to suspend disbelief or distort normal thoughts, such as "Pretend you are weightless."

Depending on the person's mental state and personality, the entire hypnotism process can take anywhere from a few minutes to more than a half hour. Hypnotists and hypnotism proponents see the peculiar mental state as a powerful tool with a wide range of applications. In the next section, we'll look at some of the more common uses of hypnotism.
