This study shows quite clearly that those bodily mechanisms represented by respiratory and cardiac activity show little or no disturbance in their normal rate and rhythm following sensory stimuli in the hypnotic trance. In the normal waking state these same indicators invariably showed a disturbance in both rate and rhythm. The verbal report of the subjects as to the sensations perceived was substantiated by the objective record in both the waking and trance states.
