    As a society has been more developed, people have been suffering from more stress. Since the stress have accompanied with physiological variations, the study that tends to quantity stress has been attempting. The objective of this study is for supporting a basic data to the research or item development which is trying to diminish a stress, according to extraction of stress index using physiological signal variations. The calculation stimulation and CPT(continuous performance test) were used as stress stimulation. RSP(respiration), SCR(skin conductance response), EEG (electroencephalgram), ECG(electrocardiogram) and SKT(skin temperature) were measured as physiological signals. Subjective survey was measured to observe psychological variations after and before stress stimulation. Experimental results have shown that heart rate and SCR have the obvious variations after and before stress stimulation. We confirmed that heart rate and SCR could be a parameter to extraction of stress index, and finally extracted stress index which could divide stress into 3 levels.
