Hypnotic induction is the process undertaken by a hypnotist to establish the state or conditions required for hypnosis to occur.
The swinging watch and intense eye gaze -- staples of hypnotic induction in film and television -- are not used in practice as the rapidly changing movements, and the obvious cliché of their application, would be distracting rather than focusing.
[8] Oliver Zangwill pointed out in opposition that, while cultural expectations are important in hypnotic induction, seeing hypnosis only as a conscious process of influence fails to account for such phenomena as posthypnotic amnesia or post-hypnotic suggestion.
Methods were designed to relax the hypnotic subject into a state of inner focus (during which their imagination would come to the forefront) and the hypnotist would be better able to influence them and help them effect changes at the subconscious level.
During this brief window of distraction the hypnotist quickly intervenes, allowing the subject to enter the state of intense, hyper imagination and inner focus.
