Abstract

The present experiment tested the hypothesis that differential neuroendocrine elicitation is prompted by subjects' cognitive expectations of art acute stressor. Subjects making a 'challenge appraisal' of an academic exam were predicted to have increased sympathetic neuroendocrine activation, while this relation to these variables was also examined. Sympathetic adrenomedullary activation was assessed via urinary catecholamines at three time points: time I (at least one week prior to the exam), time 2 (immediately prior to the exam), and time 3 (immediately after the exam). Contrary to the hypothesis, the threat group had higher adrenomedullary activation than the challenge group in anticipation of the exam (time 2). During the exam (assessed by time 3), overall adrenomedullary activation dropped regardless of cognitive appraisal group. There was a robust positive correlation between anxiety and adrenomedullary activation at baseline and pre-exam. Post-exam, this correlation continued for the challenge appraisal group only. Results demonstrated that cognitive appraisal is a significant mediator of adrenomedullary activation. Copyright (C) 2001 John Wiley & Sons, Ltd.
