| Abstract: | Repeated trials with cold-pressor pain were used to (a) determine whether the modest relation between hypnotic susceptibility and response to acupuncture analgesia obtained in previous experiments is enhanced over a series of treatments; (b) compare acupuncture and hypnotic analgesias; and (c) assess whether acupuncture analgesia increases with repeated treatments. 20 high and 20 low hypnotically susceptible undergraduates participated on 5 days. For half of each susceptibility group, Sessions 1–3 consisted of a baseline trial followed by an acupuncture analgesia trial. The remaining Ss had 2 no-treatment trials on each of these sessions. For all Ss Session 4 was a baseline followed by a hypnotic analgesia trial, and Session 5 was a repetition of the procedures followed in Sessions 1–3. Repeated exposures to acupuncture did not alter its analgesic effect in either susceptibility group; there were no instances of significant postacupuncture pain reduction. High, but not low, susceptibles reported marked pain reduction after hypnotic analgesia. The effect of acupuncture on experimentally induced pain is at best small and fragile.
