ReviewDirect versus indirect suggestions: a conceptual and methodological review.
The article reviews the literature on the effects of direct versus indirect hypnotic suggestions. A conceptual and methodological analysis of direct versus indirect suggestions is also provided. Three conclusions follow from the review: (a) Contrary to views of Ericksonian hypnotists, suggestion style has little effect on objective responding to hypnotic test items; (b) studies of clinical- and laboratory-induced pain and other measures of subjective experience have yielded contradictory results--however, the best controlled studies have not indicated that indirect suggestions are superior to direct suggestions; and (c) there is insufficient evidence to conclude that hypnotizability level and suggestion wording interact, such that low hypnotizable subjects are particularly responsive to indirect suggestions. Methodological and conceptual problems in defining and studying hypnotic communications, the lack of rigorous experimental controls, and research issues and directions are highlighted.

The effects of hypnosis and of imagery on bleeding time: a brief communication.
2 studies are reported, one using hypnotized Ss selected on hypnotizability and one using Ss selected on imagery vividness, whose purpose is to examine whether non-patient Ss can control their bleeding in a laboratory setting. All Ss were cut on both arms with the "Surgicutt" device, an instrument that automatically makes a cut that will bleed from 2 to 10 minutes. Results suggest that Ss, who are instructed to reduce the bleeding time in one arm and to let the other arm bleed normally, are not able to control bleeding time.
