Smoking cessation remains a major health priority. Despite public campaigns against smoking and widespread availability of smoking-cessation treatments, many people continue to smoke. The authors argue that the “problem of motivation,” that is, suboptimal or fluctuating motivation to resist smoking urges and to comply with the demands of treatment, commonly undermines treatment seeking and adherence, appreciably reducing the success rates of smoking-cessation programs. The authors describe the history of the Winning Edge smoking-cessation program and discuss ways to enhance motivation before, during, and after formal treatment. They illustrate how hypnotic suggestions, administered in the context of their program, can promote cognitive, behavioral, and emotional commitment to treatment and enhance motivation to live a smoke-free life.
Two experiments that studied the effects of hypnotic suggestions on tactile sensitivity are reported. Experiment 1 found that suggestions for anesthesia, as measured by both traditional psychophysical methods and signal detection procedures, were linearly related to hypnotizability. Experiment 2 employed the same methodologies in an application of the real-simulator paradigm to examine the effects of suggestions for both anesthesia and hyperesthesia. Significant effects of hypnotic suggestion on both sensitivity and bias were found in the anesthesia condition but not for the hyperesthesia condition. A new bias parameter, C’, indicated that much of the bias found in the initial analyses was artifactual, a function of changes in sensitivity across conditions. There were no behavioral differences between reals and simulators in any of the conditions, though analyses of postexperimental interviews suggested the 2 groups had very different phenomenal experiences.
Previous research using step-wise regression analyses found self-reported hypnotic depth (srHD) to be a function of suggestibility, trance state effects, and expectancy. This study sought to replicate and expand that research using a general state measure of hypnotic responsivity, the Phenomenology of Consciousness Inventory: Hypnotic Assessment Procedure (PCI-HAP). Ninety-five participants completed an Italian translation of the PCI-HAP, with srHD scores predicted from the PCI-HAP assessment items. The regression analysis replicated the previous research results. Additionally, step-wise regression analyses were able to predict the srHD score equally well using only the PCI dimension scores. These results not only replicated prior research but suggest how this methodology to assess hypnotic responsivity, when combined with more traditional neurophysiological and cognitive-behavioral methodologies, may allow for a more comprehensive understanding of that enigma called hypnosis.
This study investigated group hypnotizability in 167 adolescents (ages 13-17) in an inpatient behavioral healthcare setting through use of the Waterloo-Stanford Group Scale, Form C. It also investigated the influence of hypnotic inductions on group hypnotizability. Adolescents were randomly assigned to either a group session of hypnosis (n = 84) with a hypnotic induction or a comparison “no-induction” group (n = 83) that received identical suggestions without a hypnotic induction. Adolescents’ imaginative absorption and dissociation were measured to examine their influence on hypnotizability. A between-group comparison showed the induction condition had a significantly higher score than the no-induction group on both behavioral and subjective measures of hypnotizability.
