Ideomotor phenomenon
(重定向自Ideomotor)
Ideomotor phenomenon is a psychological phenomenon wherein a subject makes motions unconsciously.
The ideomotor response (or "ideomotor reflex"), often abbreviated to IMR, is a concept in hypnosis and psychological research. It is derived from the terms "ideo" (idea, or mental representation) and "motor" (muscular action). The phrase is most commonly used in reference to the process whereby a thought or mental image brings about a seemingly "reflexive" or automatic muscular reaction, often of minuscule degree, and potentially outside of the awareness of the subject. As in reflexive responses to pain, the body sometimes reacts reflexively with an ideomotor effect to ideas alone without the person consciously deciding to take action. The effects of automatic writing, dowsing, facilitated communication, and Ouija boards have been attributed to the phenomenon. Mystics have often attributed these effects to paranormal or supernatural force. Many subjects are unconvinced that their actions are originating solely from within themselves.
