ENGINEERING CONSIDERATIONS IN GSR RESEARCH.

Standard laboratory instruments used for detecting and recording such parameters as the electroencephalogram, electrocardiogram, galvanic skin resistance, and other phenomena, cannot meet the stringent space and power limitations levied on instrumentation in space vehicles. As a result, new miniaturized devices must be developed, often by companies previously inexperienced in the technics and requirements peculiar to bioelectronic devices. The galvanic skin resistance, a parameter of psychophysiologic interest in stressful environments, would seem to have relatively simple instrumentation requirements; however, the design engineer must be familiar with the technical and practical details peculiar to the detection and recording of this phenomenon or the result may be an instrument which is technically able to measure resistance but totally unsatisfactory for measuring skin resistance under the conditions of the experiment. This paper is a synopsis of the experiences at the USAF School of Aerospace Medicine and those reported in the recent literature concerning the critical methodological points involved in studying galvanic skin reflexes to assist the engineer and the natural scientist concerned with fabricating GSR recording apparatus.
