Hypnosis Barber's most referenced book is
Hypnosis: A Scientific Approach (1969). He argued in this work that
hypnosis and related constructs are "unnecessary and misleading and that the phenomena that have been traditionally subsumed under these terms can be better understood by utilizing a different set of concepts that are an integral part of present-day psychology." It was positively reviewed by the
scientific community. Psychologist
Theodore R. Sarbin noted that the work "demystifies and demythologizes" the subject, "the construction of hypnosis as a special mental state ha[s] no ontological footing." Throughout his numerous articles and research programs, he argued that diverse variables affected hypnotic responsiveness and that hypnosis could be elicited without any
hypnotic induction at all. He posited that contextual variables—like merely defining a situation as hypnotic or inducing goal-directed behavior—served as a theoretical basis for hypnosis. His research showed that merely priming a subject to expect to be hypnotized could produce hypnotic results, and he found that a subject's score on a hypnotic suggestibility scale could be increased through both motivation and expectation. At first perceived as an
iconoclast or "hypnosis opponent," Later in his career, Barber addressed newer but competing theories of hypnosis that were based on
dissociation. He proposed a three-dimensional description of hypnosis. He theorized that there are three distinct subtypes of good hypnotic subjects: the fantasy prone, the amnesia-prone, and the highly motivated positively set subjects.
Barber and Calverley Barber and
David Smith Calverley (1937–2008) were American
psychologists who worked and published together on measuring
hypnotic susceptibility. One result of their research was showing that the hypnotic induction was not superior to motivational instructions in producing a heightened state of suggestibility. The Barber Suggestibility Scale, a product of their research, measures
hypnotic susceptibility with or without the use of a hypnotic induction.
Birds In 1993, Barber authored
The Human Nature of Birds, a book on
animal intelligence which advocates a theory that all sentient non-human animals, notably birds have intellectual abilities. The book argues against the view that animal behaviour can solely be explained by instinct and genetic programming. Barber cited examples of caring, flexibility, language, playing, working, concept building, individuality, cause and effect understanding and musical abilities in birds. Hailman quoted Barber as saying that the "official scientific view" of birds is that they are instinctual automata but according to Hailman this has never been an official view in the fields of ethology and ornithology but Barber argued against this view many times in his book. == Other interests ==
