Hypnotic suggestibility has been described as a powerful predictor of outcomes associated with hypnotic interventions. However, there have been no systematic approaches to quantifying this effect across the literature. This meta-analysis evaluates the magnitude of the effect of hypnotic suggestibility on hypnotic outcomes in clinical settings. PsycINFO and PubMed were searched from their incept...

This study examined whether trait empathy is related to hypnotic ability and absorption. Sixty-four graduate students and mental health professionals completed the Harvard Group Scale of Hypnotic Susceptibility, Form A; the Davis Interpersonal Reactivity Index; and the Tellegen Absorption Scale as measures of hypnotic ability, empathy, and absorption. Correlation analysis determined that statis...

Forming implementation intentions has been consistently shown to be a powerful self-regulatory strategy. As the self-regulation of thoughts is important for the experience of involuntariness in the hypnotic context, investigating the effectiveness of implementation intentions on the suppression of thoughts was the focus of the present study. Participants were randomly assigned to one of four co...

In this article, hypnotic responsiveness is conceptualized as the byproduct of hypnotic ability, which is largely unalterable, plus hypnotic participation, which is highly subject to manipulation in the therapeutic context. This framework constitutes the basis of a model for the conversational assessment of hypnotic ability and hypnotic participation, as well as the subsequent tailoring of ther...

The aim of this study was to investigate the analgesic effects of hypnotic pain control on experimental pain by measuring pupil reactions as an objective psycho-physiologic parameter. Twenty-two healthy volunteers (11 female and 11 male) aged between 22 and 35 years participated in the study. Pupil diameter was measured as baseline measurement (i.e., static measurement) in the non-hypnotic and ...

One approach to hypnosis suggests that for hypnotic experience to occur frontal lobe activity must be attenuated. For example, cold control theory posits that a lack of awareness of intentions is responsible for the experience of involuntariness and/or the subjective reality of hypnotic suggestions. The mid-dorso-lateral prefrontal cortex and the ACC are candidate regions for such awareness. Al...

Procedures for estimating hypnotic depth have been used for more than 70 years. This study predicted self-reported hypnotic depth from the phenomenological and behavioral variables of the Phenomenology of Consciousness Inventory-Hypnotic Assessment Procedure (PCI-HAP). Participants were divided into 2 groups; 1 was used to generate regression equations, and the other group was used for cross-va...

STUDY OBJECTIVES Slow wave sleep (SWS) plays a critical role in body restoration and promotes brain plasticity; however, it markedly declines across the lifespan. Despite its importance, effective tools to increase SWS are rare. Here we tested whether a hypnotic suggestion to "sleep deeper" extends the amount of SWS. DESIGN Within-subject, placebo-controlled crossover design. SETTING Sleep ...

in the present work sedative and hypnotic effects of aqueous extract of aloe vera in rats have been investigated. in order to evaluate the overall hypnotic effects of the aloe vera extract, open field and loss of righting reflex tests were primarily used. the sedative and hypnotic effects of the extract were then confirmed by detection of remarkable raise in the total sleeping time through anal...
