Measurement of Emotional Response by Similarity in Patterns of Galvanic Skin Reflex

There is no doubt that many people feel the peace of mind or the pleasures of senses in appreciating music. But the estimation of the effect is very difficult and the objective estimation can be hardly done. This study proposed the objective estimating method of human emotion utilizing galvanic skin reflex (GSR) which reflects a human psychological activity. In this method, not by individual response, but by the series of response and pattern of appearance of GSR, the emotional response under appreciating music was investigated. In the case of appreciation of the same classic music to several subjects, the individual GSR responses are random and remarkable characteristic could not be find on the results. However, on the patterns of appearance of GSR, the patterns obtaining from the same generation are much similar each other and the patterns obtaining from different generation are less similar. It was cleared that the same music gave different effect on different generations

Instantaneous measurement of electrical parameters in a palm during electrodermal activity

The determination of impedance can be performed by means of a frequency-domain analysis or a time-domain analysis. The latter has the advantage of being able to measure instantaneously all the frequency characteristics of impedance. The method is hence well suited to obtain the biological impedance which changes with time. An instantaneous method of measuring skin impedance, by using time-domain analysis has thus been developed. The fast Fourier transform (FFT) of the step response for current to the skin can determine the palm impedance. This method can carry out the determination of the parameters of the palm skin impedance during a galvanic skin reflex (GSR), which is impossible by means of frequency-domain analysis </p
