A hypnotic induction produces different patterns of spontaneous experiences across individuals. The magnitude and characteristics of these responses covary moderately with hypnotic suggestibility, but also differ within levels of hypnotic suggestibility. This study sought to identify discrete phenomenological profiles in response to a hypnotic induction and assess whether experiential variabili...

BACKGROUND Several studies have shown that response expectancies are an important mechanism of popular psychological interventions for pain. However, there has been no research on whether response expectancies and treatment credibility independently mediate hypnotic and cognitive-behavioral pain interventions and whether the pattern of mediation is affected by experience with the interventions....

The effects of a guided neutral and unpleasant imagery involving several sensory modalities were studied in hypnotized subjects. Heart rate (HR), respiratory frequency (RF), tonic skin resistance and different electroencephalographic rhythms were evaluated during a long-lasting hypnotic session including the guided suggestion of a neutral (NS) and an unpleasant (US) imagery, each preceded by a ...

This paper reviews the relationships between trance or altered state effects, suggestibility, and expectancy as these concepts are defined in the theorizing of Weitzenhoffer (2002), Holroyd (2003), Kirsch (1991), and others, for the purpose of demonstrating how these concepts can be assessed with the PCI-HAP (Phenomenology of Consciousness Inventory: Hypnotic Assessment Procedure; Pekala, 1995a...

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...
