Hypnotic suggestibility, cognitive inhibition, and dissociation

Area of Science:

• Psychology
• Cognitive Neuroscience
• Hypnosis Research

Background:

• Dissociation is central to major hypnosis theories.
• Cognitive inhibition is theorized to underlie hypnotic responding.
• Existing theories lack empirical validation regarding these correlates.

Purpose of the Study:

• To investigate the relationship between hypnotic suggestibility, dissociation, and cognitive inhibition.
• To test the predictive power of dissociation and cognitive inhibition on hypnotic suggestibility.
• To identify potential gender differences in these relationships.

Main Methods:

• Administered the Waterloo-Stanford Group Scale of Hypnotic Susceptibility, Form C.
• Utilized the Dissociative Experiences Scale for dissociation assessment.
• Employed latent inhibition and negative priming tasks for cognitive inhibition measurement in 180 participants.

Main Results:

• No moderate correlations were found between hypnotic suggestibility and measures of dissociation.
• Cognitive inhibition measures did not correlate significantly with hypnotic suggestibility.
• Significant gender differences were observed in the data, warranting further investigation.

Conclusions:

• The findings challenge prominent theories of hypnosis that link suggestibility to dissociation and cognitive inhibition.
• Current theoretical frameworks may need revision to account for the lack of correlation.
• Gender differences suggest a complex interplay of factors influencing hypnotic suggestibility.
