August Research Snippet: Hypnosis, Pain, Expectation & Placebo

This snippet discusses a recent experimental study which attempted to quantify (as a percentage) the extent to which expectation contributed to the pain-reducing effects of hypnosis, imagination, and a placebo medication. Strong evidence was derived from statistical analysis suggesting that the effect of hypnotism is “partially-mediated” by expectation, albeit to a lesser degree than the placebo effect.
