“…In contrast, a close coupling between heart rate and respiratory frequency was reported [3,10]. There are conflicting reports concerning the influence of hypnosis on heart rate and other autonomic variables [4,5,8,21, 24±26]. It should be noted that psychophysiological measurements are susceptible to various endogenous and exogenous stimuli such as, among others, thoughts, emotions of the subject him/herself, unintentional or intentional emotive hypnotic suggestions, disquieting influence of the experimenters recording the measurements, and environmental disturbances.…”

The goal of the present study was to investigate whether suggestions for cold or warmth during hypnosis affect fingertip skin temperature. Hypnosis without specific suggestions for cold or warmth (`neutral hypnosis') caused a drop in respiration frequency, however, pulse rate, fingertip skin temperature, and electrodermal activity were not affected. The cold and warmth suggestions decreased and increased fingertip skin temperature, respectively. Compared with the neutral trance phase, the other three autonomic variables measured were also affected by suggestions for cold. However, there was no association between the changes in autonomic variables induced by suggestions and hypnotizability scores measured by the `Stanford Hypnotic Clinical Scale for Adults'. Fingertip skin temperature was mostly affected when the images used for the cold and warmth suggestions during hypnosis included experiences of physical temperature and psychological stress or relaxation, indicating that the psychological content of the imagery amplified the autonomic response.

“…The authors concluded that the decreased autonomic measures resulted from suggestions for relaxation rather than induction of neutral hypnosis. The design of this study (Crasilneck & Hall, 1960), however, fails to rule out the possibility that decreases in blood pressure and heart rate did result from the induction of neutral hypnosis, but that these changes were not greater than those found in a group of presumably hypnotically responsive Ss who elicited the relaxation response in an awake, relaxed state. Barber and Hahn (1963) reported decreased heart rate, respiratory rate, and palmar conductance in Ss who had either undergone a traditional hypnotic induction technique or who had been instructed to sit quietly.…”

“…191." Crasilneck andHall (1960) measured heart rate and blood pressure changes to determine whether decreases in these parameters were attributable to the state of neutral hypnosis or to the suggestions for relaxation during induction. The Ss were relaxed but awake.…”

PROBLEMWhile the use of two or more hypnotists has occurred in many studies, there has been only casual mention of this variable in the investigations('*) of other areas of h nosis and no specific empirical measure of its e g c t . Crasilneck and Hall(S), measurin physiological effects in hypnosis, found that wtenever the junior operator was resent there were changes in measurements. gilgard (6) reports little difference in the success of different h notists. Kroger (7) states that hypnosis is not9ependent upon the hypnotist and S may be tranriferred to another h notist. A study of the relative success of a and a female h notist by the Weitzenh~ffers(~) revealed no. &nm attributable to the sex of the hypnotist.Thm study investigated the effect of changing hypnotists during hypnosis on the depth of hypnosis and ability of S to follow suggestions as measured by performance of specific task items throughout two hypnotic sessions. METHODSubjects. The sub'ects were nine coeds, aged 18 to 21 years.. All As were. volunteers who had not been prewously hypnotized.Procedure. The hypnosis check list was a modified version of the induction procedure of Reiff and Scheerer(8) consisting of 13 tasks ranging. from eye closure to somnambulism. Five h notists were used. Hypnotist A (H-A) a n f i o u r junior experimenters (JE), three male and one female hypnotists. H-A initiated the individual hypnotic procedure. Ss had to respond to all suggestions on the check list. During the "somnambuliisticJJ state, S was given a five item preference questionnaire by the JE for a measured effect of hypnotist change. Upon completion of this and wlthout any suggestions of change in h notist, S was dehypnotiz$ by H-A. J E teat&call from the questionnme. JE erformed a hypnotic induction procedure simiir tp that used by H-A in the first induction, and with the same critena. H-A interrupted JE's m i o n at random and subsequently terminated the experiment. RESULTSboth experimenters indicated no observable differ ence in S's behavioral response to either hypnotist of either sex or during the unannounced changes from one hypnotist to the other. Results indicate that S will perform tasks during hypnosis a t the instance of a person other than the imtial hypnotist and independent of any particular hypnotic procedure.SUMMARY measure the effect of hypnotlst change on deptg of hypnosis and ability of S to follow instructions.Nine coeds were alternately hypnotized by a senior h notist and one of four junior hypnotists. 3 s com leted a check list of hypnotic performance a n 8 filled out a questionnaire for which they were tested after hypnosis. No observable difference in depth or measured task responses was noted from one hypnotist to the other during hypnosis or between hypnotic REFERENCES 1. As, ARVID.
