It is our purposes in this study to differentiate the hypnotic sleep from the hypnotic trance and natural sleep and to investigate the nature of hypnotic sleep by means of the physiological indications.The hypnotic sleep is what C. L. Hull observed in one of his subjects and Barker and Burgwin found during EEG recording in hypnotic trance.This hypnotic sleep was subdivided into two states in our experiment; the hypnotic sleep I and hypnotic sleep II In the former, there is a rapport between experimenter and subject, whereas there is no rapport between them in the latter.Three students (male 1 and female 2) were employed as the subject, and induced to hypnotic sleep experimentally by giving the suggestion of sleep after the occurrences of hypnotic catalepsy and amnesia in hypnotic trance.We compared it with waking state, hypnotic trance and natural sleep by the simultaneous recordings of electroencephaloraphy (EEG), electrocardioraphy (ECG), galvanic skin response (GSR) and pattelar reflex. The introspection method, histogram method and Fourier analysis were used for the analysis of EEG, and examined their relationships each other.The results of these experiments are as follows:1) The hypnotic trance is different from the waking state in appearence. In this state α wave-fast and β wave in EEG appear, and pulse rate increases, while pattelar reflex decreases.2) In the hypnotic sleep I, θ and δ waves of low voltage appear, while, in hypnotic sleep II and natural sleep, θ and δ waves of high voltage and spindle waves appear.3) In this state, the subjects responded to the instruction of experimenter, though slow waves in EEG appeared.4) It is found that there is no transience from the slow waves of low voltage in EEG to those of high voltage, but α patterns recover rapidly with cessation of sleep suggestion.5) The hypnotic sleep I is different from the hypnotic sleep II from the results of EEG, pulse rate, knee jerk and subject's observation.6) It is not found that there are any significant differences between hypnotic sleep II and natural sleep from the resuls of EEG, ECG, GSR, and pattelar reflex.7) We can conclude the following:a) The hypnotic trance is apparently different from the waking state and natural sleep.b) The hypnotic sleep which includes the factor of hypnosis and sleep between hypnotic trance and natural sleep exist. And it is the hypnotic sleep I which we insist.c) The hypnotic sleep I has a certain specific nature different from the waking state, hypnotic trance and natural sleep.
