Developing hypnotic analogues of clinical delusions: mirrored-self misidentification

Area of Science:

• Psychology
• Neuroscience
• Psychiatry

Background:

• Current research on delusional beliefs lacks viable laboratory models.
• Hypnosis offers a method to induce transient, challenge-resistant delusions.

Purpose of the Study:

• To develop a hypnotic analogue for studying mirrored-self misidentification.
• To investigate the phenomenological experience of hypnotic delusions.

Main Methods:

• Twelve highly hypnotizable participants received hypnotic suggestions to misidentify their reflection.
• Delusional beliefs were challenged, and the Experiential Analysis Technique explored subjective experiences.

Main Results:

• Most participants failed to recognize their reflection.
• Participants described the reflection as a stranger with different physical characteristics.
• The induced delusion remained robust even when challenged.

Conclusions:

• Hypnotic suggestion effectively created a compelling mirrored-self misidentification delusion.
• Findings suggest a potential role for lowered hypothesis-testing criteria in clinical delusions.
• This model provides a novel approach to studying the mechanisms of delusional beliefs.
