The relationship between hypnotizability and somatic illness was measured in 45 college students. Several weeks after completing the Waterloo-Stanford Group C Scale (WSGC), participants filled out a somatic-complaint checklist and measures of psychopathology. Results indicated a positive correlation between hypnotizability and somatic illness, and the relationship was stronger for female participants. In contrast to the quadratic model proposed by Wickramasekera, the current data demonstrated a linear relationship between hypnotizability and somatic complaint. Further analyses showed that somatic complaints were associated with hallucination and imagery items, corresponding to the perceptual-cognitive factor identified in Woody, Barnier, and McConkey's (2005) factor analysis of the Stanford Hypnotic Susceptibility Scale, Form C. The results call into question some claims that high hypnotizability is an adaptive and healthy trait.

Hypnotic Modulation of Autonomic Nervous System (ANS) Activity.

Hypnosis, a time-honored therapeutic approach, has gained widespread recognition for its effectiveness in addressing a range of psychological and somatic disorders. While its primary effects are mediated by central top-down mechanisms, hypnosis also exerts peripheral influence by modulating the autonomic nervous system (ANS). Psychophysiological measures, such as heart rate (HR) and its variability (HRV), electrodermal activity (EDA), respiratory rate (RR), and the analgesia nociceptive index (ANI), serve as reliable indicators of ANS activity.

Using multi-modal brain imaging techniques we found pronounced changes in neuronal activity after hypnotic trance induction whereby state changes seem to occur synchronously with the specific induction instructions. In clinical patients, hypnosis proved to be a powerful method in inhibiting the reaction of the fear circuitry structures. The aim of the present paper is to critically discuss the limitations of the current neuroscientific research database in the light of a debate in defining relevant hypnotic constructs and to suggest ideas for future research projects.

The reliability and factor structure of the adapted scale was compared with that of the original (American) scale and with data from two other versions (British and Puerto Rican samples). Sex differences in suggestibility were also analyzed.

Cancer affects a growing proportion of the population as survival improves. The illness and its treatment brings a substantial burden of symptoms, including pain, anxiety, insomnia, and grief. Here, the uses of hypnosis in the treatment of these cancer-related problems will be reviewed.

We also investigated how placebo analgesia affects somatic responses (eye blink) and N100 and P200 waves of event-related potentials (ERPs) elicited by auditory startle probes. Although expectation plays an important role in placebo and hypnotic analgesia, the neural mechanisms underlying these treatments are still poorly understood.
