Highly hypnotizable individuals (Highs) and low hypnotizable individuals (Lows) exhibit distinct postural control differences when closing their eyes. These findings suggest unique attentional and arousal system interactions influencing hypnotic susceptibility and balance.

Area of Science:

  • Neuroscience
  • Psychology
  • Human Physiology

Background:

  • Hypnotic susceptibility correlates with attentional and imagery capabilities.
  • Postural control is influenced by visual input and attentional states.
  • Differences in basal and task conditions exist between high (Highs) and low (Lows) hypnotizable subjects.

Purpose of the Study:

  • To investigate differences in postural control between Highs and Lows during eyes closure.
  • To explore the relationship between attentional capabilities and hypnotic susceptibility in postural control.
  • To examine how visual and motor imagery influence balance in different hypnotic susceptibility groups.

Main Methods:

  • Psychological assessments of visual/motor imagery and attentional capabilities.

  • Postural sway monitoring using Elite systems during upright stance (eyes open/closed).
  • Comparative analysis of body sway modulation between Highs and Lows.

    • Main Results:

    • Significant differences in body sway modulation were observed between Highs and Lows upon eyes closure.
    • Highs and Lows demonstrated distinct responses to postural challenges with visual input removed.
    • Attentional and arousal system differences likely contribute to observed postural control variations.

    Conclusions:

    • Hypnotic susceptibility is associated with differential postural control mechanisms, particularly when visual cues are absent.
    • Attentional and arousal systems play a crucial role in both hypnotic phenomena and maintaining upright stance.
    • Further research into compensatory strategies in Highs and Lows is warranted.
