Foundations, History, and Theories of Clinical Hypnosis
What the exam expects
You must be able to place hypnosis in intellectual history without turning it into trivia. Know the lineage: Mesmer's animal magnetism and its collapse under the 1784 Franklin commission, which shifted attention from magnetic fluid to imagination and suggestion; Braid's coinage of hypnotism and his eye-fixation method; Liébeault and Bernheim's Nancy school, which framed hypnotic response as ordinary suggestibility; Charcot's Salpêtrière position treating hypnosis as a pathological state tied to hysteria; and the later convergence on hypnosis as an altered attentional state available to most people. In the twentieth century, know that Clark Hull's laboratory work reframed suggestibility as measurable, Hilgard introduced the neodissociation perspective with a hidden observer, and social-cognitive theorists such as Sarbin and Barber argued that hypnotic behavior reflects role enactment, expectancy, and motivation rather than a special trance.
Concepts candidates confuse
Distinguish state theories (hypnosis as a genuine alteration of consciousness) from nonstate or sociocognitive theories (hypnosis as imaginative involvement shaped by context). Know the logic of the hypnotic induction profile and the idea of hypnotizability as a stable, measurable trait with a normal distribution. Understand that responsiveness is not gullibility, not weak-mindedness, and not a sign of pathology.
Traps
Questions often imply that a historical figure "proved" hypnosis is a trance; the safer answer is that evidence supports both state-like changes in attention and strong contextual effects. Another trap conflates Mesmer's fluid theory with modern practice. Do not attribute the term hypnosis to Mesmer.
Rule of thumb
Anchor every theory answer on the question: Where does the explanatory weight sit - in an altered state, or in expectancy, suggestion, and context? That single question resolves most history-and-theory items.
Worked example
A stem says a clinician explains a patient's response as "role enactment driven by expectation." The correct attribution is the sociocognitive tradition, not Hilgard's neodissociation.
