Key Points on Hypnosis

The Nature of Hypnosis

  • Hypnosis creates a state of consciousness similar to other conscious states.
  • EEG studies show predominance of alpha and beta waves in hypnotic trances, similar to relaxed waking states (Williams & Gruzelier, 2001).
  • Differences in brain activity observed in highly hypnotizable individuals or those expecting hypnosis (Callara et al., 2023).
  • Brain-imaging studies reveal activation in widespread cortical areas during hypnosis, including:
    • Occipital lobes
    • Parietal lobes
    • Sensorimotor cortex
    • Prefrontal cortex (Parris, 2017).
  • Similar activation patterns found in nonhypnotic waking states during mental imagery.

The Four Steps in Hypnosis

  1. Minimize distractions and ensure comfort of the participant.
  2. Instruct the individual to focus on a specific object or scene.
  3. Inform the participant of expected experiences, such as relaxation.
  4. Suggest events/feelings that the individual will experience, e.g., "Your eyes are getting tired."
    • Acceptance of these suggestions increases the participant's suggestibility.
