Extended North Carolina Scale

The Extended North Carolina Scale has been used in a large number of experiments in my laboratory, primarily where experienced hypnotic subjects are used repeatedly in various experiments, it is similar to the North Carolina Scale 61, 63, 80 with the addition that subjects are told that there is really no "top" to the scale, that it is possible for them to go considerably deeply into hypnosis than the defined points.

In the experimental session reported below, I explained to William that the purpose of the session was to find out what hypnosis meant to him personally. Specifically, he was informally interviewed for about an hour to determine what he usually experienced under hypnosis, other than his reactions to specifically suggested phenomena, and, if possible, what depth level, according to the Extended North Carolina Scale, he was at when he experienced these particular things. I then hypnotized him and at each 10-point interval on a depth continuum I asked William to remain at that depth and describe whatever it was he was experiencing. No particular probing was done except for phenomena already mentioned by William the emphasis was on his individual hypnotic experience. William also agreed to attempt to go much deeper than he ever had gone before.
