Eating Behavior—Choice or Reconstruction of Past Experience? A Randomized Clinical Trial of Changing Eating Intentions of Healthy Adults Through Hypnotic Suggestions

Recent meta-analyses have shown that psychological interventions have a small to medium effect on weight loss. We propose here a different approach to changing eating intentions. According to the Free Will literature, people decide to act before they acknowledge it, and they decide based on the reconstruction of previous experiences. The action can thus be inhibited immediately (max 100 ms) after awareness. We wanted to test if intervention based on this model, using hypnotic suggestions, can effectively change the intentions of eating. This study aims to identify which format of hypnotic suggestion can be more effective in changing eating intentions regarding high-calorie foods. Therefore, 88 healthy adult participants randomized in four groups received one session of hypnotic induction and suggestions or placebo. We measured the eating intentions through a computer task in which participants could choose pictures of low and high caloric food before, during, and after hypnosis. For the within-subject effect, results showed that two types of hypnotic suggestions significantly impacted the intentions of eating on high-calorie foods with large-effect, namely Cognitive Rehearsal (d = 0.81, p < .001) and Memory Substitution (d = 0.82, p < .001). After controlling for pretest ratings, we found a significant between-effect: the Cognitive Rehearsal group differed significantly from the Control in terms of intentions of eating (d = 0.85, p < .05). We conclude that hypnosis with Cognitive Rehearsal suggestions can help to positively impact the intentions of eating.     

Hypnosis and belief: A review of hypnotic delusions

Hypnosis can create temporary, but highly compelling alterations in belief. As such, it can be used to model many aspects of clinical delusions in the laboratory. This approach allows researchers to recreate features of delusions on demand and examine underlying processes with a high level of experimental control. This paper reviews studies that have used hypnosis to model delusions in this way. First, the paper reviews studies that have focused on reproducing the surface features of delusions, such as their high levels of subjective conviction and strong resistance to counter-evidence. Second, the paper reviews studies that have focused on modelling underlying processes of delusions, including anomalous experiences or cognitive deficits that underpin specific delusional beliefs. Finally, the paper evaluates this body of research as a whole. The paper discusses advantages and limitations of using hypnotic models to study delusions and suggests some directions for future research.     

Memory in a Whiteheadian Perspective

Whitehead does not provide us with a systematic account of the various types of experience to which the word “memory” is applied. Nevertheless, he does provide us with a way of understanding the world, and living creatures who inhabit it, that places the discussion in a different context from the usual one: the diverse features of human experience that we call memory are developed forms of basic patterns of relationship that characterize all actual entities. I will first review the relevant features of Whitehead's conceptuality, then contrast the resulting view with its usual formulation, and then speculate about some forms of memory in Whiteheadian categories.     

Implications of MDMA use for prospective memory function and substance use patterns in an Australian sample: A web‐based pilot study

The use of amphetamine type stimulants, particularly MDMA, is a global concern. Little research has been conducted on the association between MDMA use and everyday memory function—prospective memory. Twenty‐five MDMA users, 37 cannabis users, and 43 illicit substance‐naïve controls were assessed on their substance use history and reported prospective memory performance as measured by the Prospective Memory Questionnaire (PMQ) using a web‐based survey. There were significant differences between MDMA users and controls and cannabis users and controls on long‐term episodic subscale of the PMQ. However, given the high prevalence of cannabis co‐use by MDMA users, it was not possible to determine if MDMA use alone is associated with prospective memory performance. The substance use patterns of the sample were evaluated. Alcohol was the most used substance followed by tobacco, cannabis, and MDMA. The incidence of polydrug use was high, with all illicit substance use reporting having used at least two substances in their lifetime. The present study supports previous research into prospective memory deficits associated with substance use, and provides a basis for future research, particularly for elucidation of prospective memory deficits specific to MDMA use and further evaluation of substance use patterns.

Is there a future for investigative hypnosis?

Since its heyday in the 1970s and 1980s, hypnosis as an investigative procedure has declined in popularity such that many experts now consider it to be more a liability than a useful forensic tool. Indeed, in the US, a majority of the states follow a per se exclusion rule, prohibiting any memories retrieved during or after hypnosis from being introduced into evidence. In this paper, factors contributing to the demise of investigative hypnosis are re-examined. It is concluded that a per se exclusion rule is overly inclusive, but it is advisable for investigators to avoid using hypnosis when other, less contentious alternatives, such as the cognitive interview, are available. Nevertheless, it often goes unrecognised that a more positive legacy of investigative hypnosis is very present in modern investigative interviewing best practice; moreover, there may still be procedures employed in hypnotic interviewing that have yet to be exploited. For example, recent research indicates that, when divorced from the context of hypnosis, brief techniques such as focused breathing, and eye closure, can enhance memory. As memory enhancement with these techniques is achieved without the increase in false positive errors familiar to more traditional hypnosis techniques, evidence from such procedures should be acceptable to the courts. The potential role of hypnosis as a tool to reverse the effects of misinformation is also considered. Copyright © 2009 John Wiley & Sons, Ltd.     

The Application of Facilitated Imagery to Marital Counseling

SUMMARY

The purpose of this study was to assess whether facilitated imagery is a successful technique for improving both marital satisfaction and individual psychological functioning. Twenty marital couples were randomly assigned to two experimental groups: Both received three sessions of structured marital enrichment and one also received three facilitated imagery sessions. Posttests were given at one month and four months following treatment. Subjects exposed to facilitated imagery showed significantly greater improvement on some scales of marital satisfaction and individual psychological functioning, and these improvements persisted at the four-month posttest. In posttest interviews, subjects reported the primary benefit was insight into themselves and their spouses.

A series of 2x(3) repeated measure analyses of variance were used to detect changes for husbands and wives. Subjects exposed to facilitated imagery reported significantly greater improvement than enrichment-only subjects on some scales of marital satisfaction and individual psychological functioning. In addition, improvements persisted at the four-month posttest for the enrichment-plus-imagery subjects, but declined for the enrichment-only subjects. In interviews, the majority of imagery subjects reported that the process had been helpful to them both personally and relationally. Subjectively they reported gaining insight into themselves or their spouse as the primary benefit obtained from the imagery work.

A behavioral medicine intervention as an adjunctive treatment for HIV-related illness

Abstract

This investigation assessed the efficacy of a behavioral medicine intervention in the adjunctive treatment of symptomatic HIV seropositive men. Twenty-six, well coping, seropositive gay males were randomly assigned to either a treatment group or a waiting list control group. The treatment group received eight weeks of training in thermal biofeedback, guided imagery and hypnosis Significant results (p < 0.05) indicated that HIV-related symptoms (fever, fatigue, pain, headache, nausea and insomnia) decreased and that vigor and hardiness increased. No significant changes were found in absolute numbers of CD4 cells, tension-anxiety or depression.
