An experiment to find out if the emotional fluctuation was reflected in biological responses.

Abstract The experiment was to find out if the aroused vacillation was reflected in biological results. Galvanic undress conductance, pulse and put down bind interval was apply as indicators to measure the sensational fluctuation of the subject. These informations were pick up by a information processing system finished applying electrodes to the experimental subject. It was found that the actual statistical take did taking into custody with the expected outcome; there was a significant shift in biological responses to stimuli, when the stimuli was presented in an unhoped-for format or the content of the stimuli itself was small to the subject. The galvanic scrape response (GSR), besides known as the psychlogalvanic reflex (PGR) and electrodermal response (EDR), is the most sensitive physiological indicator of psychological events for sale to the psychologist. (Montagu, J. D. & antiophthalmic factor; Coles, E. M., 1966) It is a convenient and sensitive index of i nvoluntary arousal that has been used as a measure of emotion in laboratory studies. GSR cover both translucent but tie in phenomena, they are the drop in the galvanising resistance of the skin to the going of an applied reliable which is discovered by Fere(1888) and the alter in the natural capableness difference between 2 areas of the body surface which is the phenomenon of Tarchanoff(1890).

Although the decimal relationship between them is uncertain, these two phenomena normally occur ad lib (Montagu, 1958). In our experience, we would focus on the change in the electrical resistance of the sin to the passage of an applied current. Regarding the periph! eral utensil of the GSR, there have been ternion basic theories: the muscular theory, the vascular theory and the secretory theory. (Montagu, J. D. & Coles, E. M., 1966) The muscular theory attributed the electrical changes to muscular activity beneath the skin at the localise of the electrode (Sidis & Nelson, 1910). The...
