This study found no evidence of brain hemisphere differences in hypnosis response. Hypnotizability was similar across left- and right-handed individuals and body sides.

Area of Science:

  • Neuroscience
  • Psychology

Background:

  • Hypnosis is a state of consciousness involving focused attention and reduced peripheral awareness.
  • Previous research has explored potential links between hemispheric lateralization and hypnotic susceptibility.

Purpose of the Study:

  • To investigate whether hemispheric activity during hypnosis differs between the left and right sides of the body.
  • To examine if handedness or seating position influences hypnotizability.

Main Methods:

  • 1269 participants completed hypnotizability scales with suggestions targeting the left or right side of the body.
  • Data were analyzed to compare response strength based on body side, handedness, and seating position.

Main Results:

  • No consistent differences in response strength were observed between the left and right sides of the body.

  • Hypnotizability did not differ significantly between right-handed, left-handed, or ambidextrous participants.
  • Seating position (left vs. right side of the room) did not correlate with hypnotizability.

    • Conclusions:

    • This study did not find evidence supporting lateralized cerebral activity during hypnosis based on behavioral responses.
    • Direct neuroimaging or electrophysiological studies are needed to definitively assess hemispheric involvement in hypnosis and hypnotizability.
