Abstract

Tn the present study, 9 photographs from the International Affective Picture System (IAPS) judged to express best 2-dimensional sensibility were selected and used to stimulate the subjects. The goal of the study lay in verifying whether or not the consequent affective changes in the subjects can be discriminated psychologically and physiologically in terms of arousal and relaxation. In order to determine affective changes, the physiological signals of the subjects' autonomic nervous system were measured through electrocardiogram (ECG) , galvanic skin response (GSR), skin temperature, and respiration. After stimulation and measurement, subjective evaluation was conducted. Subjective evaluation revealed that affective arousal level could be classified into 4 consecutive stages: arousal 〉 unpleasant arousal, pleasant arousal 〉 comfort 〉 relaxation. Analysis revealed that the responses of the autonomic nervous system, too, could be classified into 3 consecutive stages: arousal, unpleasant arousal, pleasant arousal 〉 comfort 〉 relaxation. By selecting and using 9 photographs from the IAPS deemed best to express Koreans'2-dimensional sensibility, the present study confirmed that it is possible to discriminate changes in the subjects' affective arousal level in terms of arousal and relaxation through psychological and physiological evaluation.
