Suggestibility, expectancy, trance state effects, and hypnotic depth: I. Implications for understanding hypnotism

Area of Science:

• Psychology
• Neuroscience
• Consciousness Studies

Background:

• Hypnosis research often focuses on behavioral traits.
• Understanding the subjective experience of hypnosis is crucial.
• Existing theoretical frameworks define trance, suggestibility, and expectancy in hypnosis.

Purpose of the Study:

• To review the relationships between trance, suggestibility, and expectancy in hypnosis.
• To demonstrate the assessment of these concepts using the Phenomenology of Consciousness Inventory: Hypnotic Assessment Procedure (PCI-HAP).
• To discuss the utility of PCI-HAP in measuring hypnotic responsivity from a phenomenological perspective.

Main Methods:

• Review of theoretical frameworks by Weitzenhoffer, Holroyd, and Kirsch.
• Introduction and application of the Phenomenology of Consciousness Inventory: Hypnotic Assessment Procedure (PCI-HAP).
• Discussion of self-reported hypnotic depth and its relation to key variables.

Main Results:

• The PCI-HAP offers a method to assess trance, suggestibility, and expectancy.
• It provides a phenomenological approach to measuring hypnotic responsivity.
• The study lays the groundwork for future research on the PCI-HAP model.

Conclusions:

• The PCI-HAP is a valuable tool for understanding the subjective aspects of hypnosis.
• It complements traditional behavioral assessments of hypnotic traits.
• Further research will validate the PCI-HAP model for understanding hypnotism.
