Hypnosis

Hypnosis is a human condition involving focused attention (the selective attention/selective inattention hypothesis, SASI), reduced peripheral awareness, and an enhanced capacity to respond to suggestion. There are competing theories explaining hypnosis and related phenomena. Altered state theories see hypnosis as an altered state of mind or trance, marked by a level of awareness different from the ordinary state of consciousness. In contrast, non-state theories see hypnosis as, variously, a type of placebo effect, a redefinition of an interaction with a therapist or a form of imaginative role enactment.
