INFLUENCE OF COOLING OF ADJACENT AREAS ON GSR AND BASE RESISTANCE OF AN ISOTHERMAL SITE

摘要

In a simulation of possible field conditions, skin resistance (R) and galvanic skin response (GSR) were measured from finger sites maintained at constant temperature while adjacent areas were cooled and rewarmed. Cooling of restricted areas up to 10 cm. from the isothermal site produced negligible changes in R and variable effects on GSR amplitude. Cooling the entire hand surface to 15° C. caused an initial increase in GSR amplitude followed by a steady decline to levels as much as 50% below control while R showed only minor changes. GSR count was also altered. Results are interpreted in terms of a two-component system influencing R and GSR. It is concluded that adequate technic demands maintenance of a narrow temperature range over the entire hand or foot.
