Comprised of "Physical" and "Emotional" components, this system measures how best to communicate with the subconscious.
Over the course of his more than 30 year hypnotherapy career, Dr. John G. Kappas founded the Hypnosis Motivation Institute, College of Hypnotherapy, literally defined the terms "hypnotist", "hypnotherapist" and "hypnotherapy" for the "Dictionary of Occupational Titles" and founded both the American Hypnosis Association and the Hypnotherapist's Union Local 472.
But perhaps his biggest contribution to hypnotherapy are the models of Physical & Emotional Suggestibility and Physical & Emotional Sexuality. These models have come to form the foundation of the Kappasinian school of Hypnotherapy.
In the Kappasinian model of suggestibility, an "emotional" language processor is someone who is more analytical and reads between the lines of what is being said. A physically suggestible person processes incoming language more literally and directly. This changes how a hypnotherapist approaches both the hypnotic "induction" or method of creating a trance, as well as how the post-hypnotic suggestions are framed and worded during the session.
Because of this discovery by Dr. Kappas in 1968, people who used to be un-hypnotizable could suddenly be hypnotized by using inductions that appealed to the more emotionally suggestible (analytical) subjects.
This was a breakthrough since research prior to Dr. Kappas had simply used one type of induction, and then tested how well it worked on different kinds of people (which meant that only approximately 70% of people were hypnotizable at all).
