Abstract (in Japanese) (See Japanese page) 
(in English) Aiming for objective evaluation of emotion, to find the physiological index which enables us to evaluated psychological tension objectively, we introduced the psychological tension evoking pictures and low noise sound which has been used to as a stressor, and using these stimuli, blood circulation responses and their relations with subjective evaluation scores were investigated previously. This time, for the generality of stimulus, we introduced negative emotion-evoking videos and some straining settings as other types of stimuli. The biological responses and the relations with the subjective tension scores were analyzed as before. The subjects were twelve young adults. Plethysmograph, electrocardiogram, continuous blood pressure, respiratory wave were measured and analyzed. As a result, the responses of heart rate, systolic blood pressure and pulse wave amplitude changed significantly, and heart rate and pulse wave amplitude correlated with the subjective tension scores. Further, no parameter was correlated to unpleasant. As the responses of these biological parameters which showed significant change were due to an activation of skin sympathetic nerve activity, physiological parameters based on skin sympathetic nerve activity may represent an objective evaluation index for tension.
