This study found that a plasma ball device did not enhance hypnotic susceptibility or the perception of realness compared to standard eye fixation. No evidence suggests this device is superior for hypnotic induction.

Area of Science:

  • Psychology
  • Neuroscience

Background:

  • Historically, devices proposed to aid hypnotic induction often relied on placebo effects.
  • The efficacy of novel sensory devices for hypnosis remains largely uninvestigated.

Purpose of the Study:

  • To evaluate the efficacy of a plasma ball device in facilitating hypnotic induction.
  • To determine if combining visual and auditory stimuli enhances hypnotic susceptibility.

Main Methods:

  • 42 college students with low hypnotic susceptibility were recruited.
  • Participants were matched on hypnotizability and randomly assigned to a plasma ball (experimental) or eye fixation (control) condition.
  • Hypnotizability and realness ratings were assessed before and after the induction procedure.

Main Results:

Related Experiment Videos

  • Both groups showed significant increases in hypnotizability and realness ratings from the initial session.
  • The plasma ball device did not lead to significantly higher scores compared to the control group.
  • No significant difference in hypnotic susceptibility was observed between the experimental and control conditions.

Conclusions:

  • The plasma ball device does not offer an advantage over standard eye fixation for hypnotic induction.
  • Current evidence does not support the use of this specific device for enhancing hypnosis.
  • Further research is needed to explore potential facilitators of hypnotic induction.
