Imagination as an essential element hypnotic treatments appeared early 1784 argument rejecting theory animal magnetism Franz Anton Mesmer. In somnambulism German romanticism, another proto-form after 1800, concepts mind–body problem were dealt with, which still characterize understanding unconscious mental processes today. Hypnosis was at beginning psychoanalysis, but not pursued further by Sigmund Freud from 1900 onwards.

Motor imagery requires mental representation of the body, which is obtained by integration exteroceptive and interoceptive information. The aim study was to investigate role sensitivity in motor performed through visual kinesthetic modalities participants with low (lows, N = 26), medium (mediums, 11) high hypnotizability scores (highs, 16), measured Stanford Hypnotic Susceptibility Scale: Form A. These groups display different abilities sensitivity. efficacy chronometric index self-reported experience, Multisensory Assessment Interoceptive Awareness (MAIA) questionnaire.

In contrast, indicated better highs mediums than lows, no modality difference lows. MAIA dimensions sustained sub-jective experience almost all differences, slightly highs, This first report a major played imagery.
