Hypnotizability and Visual Imagery Inside and Outside Hypnosis: A Replication and Extension.

Area of Science:

• Psychology
• Cognitive Neuroscience
• Hypnosis Research

Background:

• Hypnotizability, or responsiveness to hypnotic suggestions, is a key area in hypnosis research.
• Imagery vividness is often considered crucial for hypnotic experiences, yet empirical evidence remains inconsistent.
• Understanding the link between imagery and hypnotizability is essential for clarifying hypnotic mechanisms.

Purpose of the Study:

• To investigate the relationship between hypnotizability and imagery vividness, both within and outside of hypnotic states.
• To differentiate between trait (general) and state (situational) imagery in relation to hypnotic susceptibility.
• To clarify the role of imagery in influencing responsiveness to hypnotic suggestions.

Main Methods:

• Assessed hypnotizability using the Harvard Group Scale of Hypnotic Susceptibility (HGSHS).
• Measured trait imagery (outside hypnosis) with the Vividness of Visual Imagery Questionnaire (VVIQ).
• Measured state imagery (during hypnosis) with the Phenomenology of Consciousness Inventory (PCI) in 56 participants.

Main Results:

• No significant correlation was found between hypnotizability and trait imagery (r = 0.13).
• A moderate correlation (r ≈ 0.45) was observed between hypnotizability and state imagery experienced during hypnosis.
• These findings indicate a contextual link between imagery vividness and hypnotic susceptibility.

Conclusions:

• General imaginative capacity (trait imagery) shows little to no relationship with hypnotizability.
• The ability to generate vivid imagery in specific contexts (state imagery) is moderately associated with higher hypnotic susceptibility.
• Situational engagement in imagery, rather than a stable individual trait, appears to be a significant factor influencing hypnotic responsiveness.
