Hypnotizability, preference for an imagic cognitive style, and memory creation in hypnosis

Area of Science:

• Psychology
• Cognitive Science
• Neuroscience

Background:

• Previous research established that hypnosis can induce pseudomemories.
• Understanding the factors influencing pseudomemory formation is crucial for memory research.

Purpose of the Study:

• To investigate the relationship between hypnotic susceptibility and pseudomemory creation.
• To examine the predictive power of non-hypnotic cognitive measures on pseudomemory formation.
• To explore the interplay of these factors in generating false memories under hypnosis.

Main Methods:

• Participants underwent hypnotic suggestions to create a specific pseudomemory.
• Hypnotic susceptibility was assessed.
• Non-hypnotic measures, including the Preference for an Imagic Cognitive Style (PICS) test and the Tellegen Absorption Scale (TAS), were administered.
• Subjective belief in the veridicality of the pseudomemory was evaluated.

Main Results:

• Highly and moderately-highly hypnotically susceptible subjects reported believing their pseudomemory was real, unlike low susceptible subjects.
• Hypnotic susceptibility and PICS scores, along with their interaction, were significant predictors of pseudomemory creation.
• The Tellegen Absorption Scale (TAS) showed a relationship with pseudomemory occurrence, but this was redundant with other measures.

Conclusions:

• Pseudomemory creation during hypnosis is a complex phenomenon influenced by multiple variables.
• Individual differences in hypnotic susceptibility and cognitive style play a key role.
• Further research is needed to fully elucidate the mechanisms underlying hypnotic pseudomemory formation.
