The purpose of this study is to evaluate psychological and physiological effects of photic feedback system (αFB) which had been developed in order to facilitate relaxation response comparing with autogenic traming (AT). The subjects were 13 healthy individuals (8 AT practiced and 5 unpracticed). All subjects experienced αFB session and AT session in turn with their eyes closed. Each αFB session consisted of a sweep period of 3 min, a rest period of 7 min, an αFB period of 10 min, a rest period of 10 min. Each AT session consisted of a rest period of 10 min, an AT period of 10 min, a rest period of 10 min. Physiological monitoring of blood pressure, heart rate (HR) and respiratory rate (RR) was performed during the sessions. As psychological measures, State trait anxiety inventoryState form (STAI-S) and Profile of mood states (POMS) were administered before and after the sessions, and post-trial subjective feeling-state reports were requested after them. The mean value and the standard deviation (SD) of systolic blood pressure (SBP), diastolic blood pressure (DBP). HR, RR and the coefficient of variance of R-R interval (CVR-R) were calculated on each of three following periods ; 7〜9 min (pre), 17〜19 min (mid), 27〜29 min (post). The data were statistically analyzed with analyses of variance by General Linear Models (GLM) procedure of Statistical Analysis System (SAS). The results were as follows ; 1) According to the results of psychological measures, almost all measures were significantly decreased, and αFB was equally effective for calming mood as AT. 2) SBP-mean and CVR-R Significantly increased, HR-mean significantly decreased. 3) SBP-SD and DBP-SD significantly increased during αFB and AT period. 4) CVR-R increased in the αFB sessions more than in the AT sessions. It is concluded that αFB was equally effective for calming mood as AT and that αFB was prone to increase parasympathetic measures such as CVR-R more than AT.
