Abstract
The purpose of this study was to examine the quality of H. R changes during the anticipatory period of shock to come whether it considered as a reflex of primary process or secondary process of emotion. According to Epstein's, two process model, if H. R changes were equivalent to the secondary processing, inverted V-shaped curve could be observed as a function of increasing intensity of situational aversiveness. In this study, the intensity of situational aversiveness was defined operationally by varying the probability of shock and availability of instrumental coping with it. As a result, inverted V-shaped curve of H. R level was obtained regardless of whether inferred curve of aversiveness and adoption of cognitive coping were represented by linear or curve linear functions.
