The skin and the nervous system develop side by side in the fetus and remain intimately interconnected and interactive throughout life. Because of the skin-nervous system interactions, there is a significant psychosomatic or behavioral component to many dermatologic conditions. This permits complementary nonpharmacologic psychotherapeutic interventions, such as acupuncture, aromatherapy, biofeedback, cognitive-behavioral therapy, hypnosis, placebo, and suggestion, to have positive impacts on many dermatologic diseases. Complementary pharmacologic psychotherapeutic interventions, such as herbs and supplements, also may help improve some dermatologic disorders.

Hypnosis is a procedure during which a mental health professional suggests that a patient experience changes in sensations, perceptions, thoughts, or behavior. The purpose of this article is to briefly describe the use of various methods of relaxation, hypnosis, and imagery techniques available to enhance athletic performance. The characteristics that these techniques have in common include relaxation, suggestibility, concentration, imaginative ability, reality testing, brain function, autonomic control, and placebo effect. Case studies are provided for illustration.

Highly hypnotizable participants were given a posthypnotic suggestion to feel a flash of disgust whenever they read an arbitrary word. They were then asked to rate moral transgressions described in vignettes that either did or did not include the disgust-inducing word. Two studies show that moral judgments can be made more severe by the presence of a flash of disgust. These findings suggest that moral judgments may be grounded in affectively laden moral intuitions.

The role of alterations in mismatch negativity (MMN) in hypnosis was examined by recording MMN of the auditory ERP at frontal (F3, Fz, and F4) and mastoid (M1 and M2) placements. Frontal MMN is believed to reflect activity in right anterior cortical generators, whereas MMN at mastoid leads reflects generators located bilaterally in the temporal auditory cortex. MMN recordings were obtained in 11 low and 12 high hypnotically susceptible participants in three successive blocks; pre-hypnosis, hypnosis and post-hypnosis. Frontal (but not temporal) MMN showed a significant quadratic trend across testing conditions. It increased during hypnosis and then dropped post-hypnosis for both susceptibility groups. Linear trends for frontal and temporal MMN showed directly opposite patterns of change in the interaction between hypnotic susceptibility and testing blocks. Frontal MMN built up linearly over the test blocks in high relative to low susceptibility participants. Temporal MMN showed the reverse pattern and increased linearly across test conditions in those with low relative to high hypnotic susceptibility.

This article studies the problem of controlling the drug administration during an anesthesia process, where muscle relaxation, analgesia, and hypnosis are regulated by means of monitored administration of specific drugs. On the basis of a seventh-order nonlinear pharmacokinetic-pharmacodynamic representation of the hypnosis process dynamics, a cascade (master/slave) feedback control structure for controlling the bispectral index (BIS) is proposed. The master controller compares the measured BIS with its reference value to provide the expired isoflurane concentration reference to the slave controller. In turn, the slave controller manipulates the anesthetic isoflurane concentration entering the anesthetic system to achieve the reference from the master controller. The advantage of the proposed cascade control structure with respect to its noncascade counterpart is that the former provides operation protection against BIS measurement failures. In fact, under a BIS measurement fault, the master control feedback is broken and the slave controller operates under a safe reference value. Extensive numerical simulations are used to illustrate the functioning of the proposed cascade control structure.

This paper presents phenomenological research conducted following Woodard's phenomenological and perceptual research methodology for understanding hypnotic experiencing. The research emphasizes examining the internal experiencings of individuals involved in hypnotic experiencing. Examples are presented of Individual Situated Structures and the General Structures from both a group of 8 participants who hypnotized their clients and another group of 17 individuals who volunteered to be hypnotized. The explicated themes identified in hypnotic experiencing (the hypnotic relationship, phenomenology of trance, use of imagination, problem with psychic energy, a gestalt of experiencing, and linear-nonlinear experiencing) are discussed. The author discusses limitations of this study and suggestions for further work.

The critical aspects of recognizing that hypnotic responses are part of everyday life for those who are hypnotizable are considered. The failure of the American Psychological Association (APA) definition to include spontaneous hypnosis is discussed along with the resultant implications for misinforming clinicians, researchers and the public.

The authors argue that the new definition of hypnosis by Division 30 of the American Psychological Association contains questionable information about the role of imagination in hypnosis, about the use versus omission of the word hypnosis in inductions, and about the nature of individual differences and their relation to the standardized scales. In addition, the definition appears to conflate formal and exemplar-based types of definition, and it does not seem particularly well-tuned to the interests of lay persons. The authors advance some suggestions for future definitional efforts.

The present study examined the facilitation of pain reduction through the use of a pain reduction protocol. The protocol emphasized converting pain sensations into visual and auditory representations, which then were manipulated through therapeutic suggestion. Hypnosis was not mentioned in the intervention, minimizing creation of expectancy effects related to hypnosis. At the conclusion of the study, the Stanford Clinical Hypnotic Scale was administered. Measures of relaxation and reduction of suffering were not related to hypnotizability. However, pain reduction was significantly related to hypnotizability (r = .55, P < .001). High hypnotizables had a greater reduction in pain than low hypnotizables, even though both had equivalent degrees of relaxation.

Binge eating frequently is related to emotional stress and mood problems. In this report, we describe a 16-year-old boy who utilized automatic word processing (AWP) and self-hypnosis techniques in treatment of his binge eating, and associated anxiety, insomnia, migraine headaches, nausea, and stomachaches. He was able to reduce his anxiety by gaining an understanding that it originated as a result of fear of failure. He developed a new cognitive strategy through AWP, after which his binge eating resolved and his other symptoms improved with the aid of self-hypnosis. Thus, AWP may have helped achieve resolution of his binge eating by uncovering the underlying psychological causes of his symptoms, and self-hypnosis may have given him a tool to implement a desired change in his behavior.
