Abstract: | There is evidence that certain physiological and subjective indices of stress are relatively great when control over aversive outcomes is moderately difficult and relatively reduced when control over such outcomes is either easy or impossible. A possible explanation is suggested by Brehm's recent theory of motivation, which asserts that energy mobilization and the perceived unpleasantness of an aversive event will (a) increase with the difficulty of avoidant behavior so long as avoidance is believed to be possible and worthwhile, and (b) be low when avoidant behavior is impossible, not worthwhile, or simply unavailable. This article reports two experiments that examined appraisals of an aversive incentive under conditions where avoidance was expected to be easy, difficult, and impossible. The first demonstrated the complete nonmonotonic pattern of appraisals predicted by the energization theory, something that has proved elusive in previous investigations. The second study demonstrated this as well and, in addition, showed a correspondence between subjects' incentive appraisals and their cardiovascular responses immediately before and during an avoidance task period. Implications and alternative interpretations are discussed.This research was supported in part by a Faculty Research Award from the University of Alabama at Birmingham. |
