In person, this looks strange enough. “There are a lot of ways to go into this state, but one way is to count to three,” Spiegel explains. “On one, you do one thing — look up. Two, two things — slowly close your eyes and take a deep breath. And three, three things — let the breath out, keep your eyes relaxed, and keep them closed. Let your body float. And then let one hand or the other float up in the air like a balloon.” When in this state, the hypnotized person’s hand will rise up into the air, as if on its own accord; Spiegel can reach over and gently pull the hand down, but it will float right back up again, as if it’s filled with helium.
State theorists interpret the effects of hypnotism as due primarily 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:
Before people subject themselves to hypnotherapy they are advised to learn as much about the process and about the chosen therapist as is necessary to feel comfortable. Rapport and trust are two key ingredients in making a potential hypnotherapy patient comfortable. Therapists should be open and willing to answer all questions regarding qualifications, expertise, and methods used. A well-qualified professional will not undertake the use of hypnosis without interviewing the patient to ascertain their level of understanding of the process. This is very important for two reasons. First, it allows the patient the opportunity to have questions answered and to develop some rapport with the therapist. Second, it is important for the therapist to know the patient's expectations since meeting these expectations will enhance the likelihood of success.
The experience of hypnosis can vary dramatically from one person to another. Some hypnotized individuals report feeling a sense of detachment or extreme relaxation during the hypnotic state while others even feel that their actions seem to occur outside of their conscious volition. Other individuals may remain fully aware and able to carry out conversations while under hypnosis.
