Results of research conducted on healthy volunteers revealed the behavioral, experiential, physiological, and interactional characteristics of the induced altered state of consciousness (ASC), showing both similarities and differences between traditional and active-alert hypnosis. A short description of the application of the method is followed by two brief case studies.
