Hypnotic age regression and the autokinetic effect.

Area of Science:

• Psychology
• Cognitive Neuroscience

Background:

• Hypnotic age regression is a technique used to access earlier memories and experiences.
• Previous research suggests potential alterations in cognitive processes under hypnosis.

Purpose of the Study:

• To investigate whether hypnotic age regression influences performance on the autokinetic illusion.
• To determine if adult subjects under age regression exhibit childlike perceptual responses.

Main Methods:

• 18 highly hypnotically susceptible adults were selected based on the Harvard Group Susceptibility Scale.
• Participants were assigned to three groups: waking control, standard hypnotic induction, and age regression.
• Responses to a circle, a man's profile, and a cross stimulus were measured using the autokinetic illusion.

Main Results:

• No significant differences were found in responses across stimulus conditions between the groups.
• Hypnotic age regression did not lead to a reinstatement of childlike performance on the perceptual illusion.

Conclusions:

• The study failed to support the hypothesis that hypnotic age regression reinstates childlike perceptual responses.
• Findings suggest limitations in current age regression paradigms for altering basic perceptual tasks.
• Implications for future research on memory, perception, and emotion under hypnosis are discussed.
