Link to the standard HGSHS:A script, as originally published by Consulting Psychologists Press, and now out of print(PDF).

Link to the HGSHS:A subject's self-report response booklet, as modified by J.F. Kihlstrom (PDF).  This version measures the experience of involuntariness on a continuous scale.

Link to the script for the Arizona Motor Scale of Hypnotizability (AMSH), a special-purpose instrument not intended for general use -- and certainly not intended as a substitute for HGSHS:A or SHSS:C.  Link to a page analyzing the performance of a normative sample of college-student subjects.

Link to a script for building rapport with subjects and patients prior to their first experience of hypnosis (PDF).

Link to a Human Subjects Protocol that covered my hypnosis research at the University of California, Berkeley (HTML).  

Link to information on the Tellegen Absorption Scale (Tellegen & Atkinson, 1973), often administered prior to a subject's first experience of hypnosis (HTML). At the request of the University of Minnesota Press, I have removed from my website a copy of the actual Absorption Scale.  For more information about the Tellegen Absorption Scale, please contact the University of Minnesota Press (and tell them their policy is silly).

Links to tests of mental imagery, often administered prior to a subject's first experience of hypnosis (HTML): 

Link to an ongoing list of literature and film involving hypnosis as a plot device.

Link to A Saga of Hypnosis: Two Decades of the Stanford Laboratory for Hypnosis Research, 1957-1979, by E.R. Hilgard.  Privately distributed on the occasion of the closing of Hilgard's laboratory, this document also served as the final report on Hilgard's long-running NIMH grant.  Summarizes the lab's activity and findings; provides a comprehensive bibliography of the lab's publications (through 1979) and Hypnosis Research Memoranda (internal documents describing pre-publication results as well as occasional observations that were never formally published; also provides a listing of all the laboratory's professional staff members and visiting scholars.
