Hypnosis

Hilgard is specifically known for his theory that a so-called "hidden observer" is created in the mind while hypnosis is taking place. His research on the hidden observer during hypnotic pain management was intended provided support for his neodissociationist theory, which held that a person undergoing hypnosis can still observe his/her own pain without consciously experiencing any suffering. The phenomenon of the "hidden observer" was controversial and critics claimed it could be manufactured by suggestions, indicating that it was possibly no more than an artifact of the instructions given to the research participants [citation or elaboration needed]. Writing in the late 1970s (Hilgard, E. (1977). Divided consciousness: Multiple controls in human thought and action. New York, NY: Wiley), Ernest Hilgard became convinced that we all have another being sharing our lives. Hilgard termed this entity the ‘‘hidden observer.’’ In one of his books, Hilgard described a classic test of how this hidden entity is part of our consciousness. He wrote of a blind student who was hypnotized and, while in a trance state, was told that he would become deaf. The suggestion was so strong that he failed to react to any form of noise, even large sounds next to his ear. Of course, he also failed to respond to any questions he was asked while in his trance state. The hypnotist was keen to discover if ‘‘anybody else’’ was able to hear. He quietly said to the student, ‘‘Perhaps there is some part of you that is hearing my voice and processing the information. If there is, I should like the index finger of your right hand to rise as a sign that this is the case’’(Hilgard, 1977, p. 186). The finger rose. At this, the student requested that
he be brought out of the hypnotically-induced period of deafness. On being‘‘awakened,’’ the student said that he had requested to come out of the trance state because ‘‘I felt my finger rise in a way that was not a spontaneous twitch, so you must have done something to make it rise, and
I want to know what you did’’ (p. 186). The hypnotist then asked him what he remembered. Because the trance was light, the student never actually lost consciousness; all that occurred was that his hearing had ceased. In order to deal with the boredom of being deprived of both sight and sound,he had decided to work on some statistical problems in his head. It was while he was doing this that he suddenly felt his finger lift. This was obviously strange to him, because under normal circumstances he was, like all of us, the ‘‘person’’ who decides on how the body moves. In this case he was not. Not only that, but ‘‘somebody else’’ in his head was responding to
an external request that he had not heard. As far as Hilgard was concerned, the person who responded was the ‘‘hidden observer.’’
One of Hilgard’s subjects made the following interesting statement about what she experienced, making particular reference to what she sensed was her higher self: The hidden observer is cognizant of everything that is going on. . . . The hidden observer sees more, he questions more, he’s aware of what is going on all of the time but getting in touch is totally unnecessary. . . .

 that guards you from doing anything that will mess you up. . . . The hidden observer is looking through the tunnel, and sees everything in the tunnel. . . . Unless someone tells me to get in touch with the hidden observer I’m not in contact. It’s just there. (Hilgard, 1977, p. 210) The hidden observer protects us from doing anything in hypnosis that we would not do under any circumstance consciously, such as causing someone else physical harm.

Textbooks

Hilgard was also the author of three hugely influential textbooks on topics other than hypnosis. The first, “Conditioning and Learning”, jointly authored with Donald Marquis, was very widely cited up until the 1960’s, and when Gregory Kimble updated a second edition in 1961, Hilgard and Marquis’s names were made part of the title, a distinction, as Hilgard himself noted, usually reserved for deceased authors. A second text, “Theories of Learning”, first published in 1948, was also widely cited, and lasted for 5 editions, the last three (the fifth was published in 1981) with the involvement of Gordon H. Bower
