Reanalyzed the data for 2 stress groups of 54 undergraduates each from a previously conducted experiment by W. F. Hodges (see record 1968-08262-001). 3 coping groups, denial, neutral, and accentuator, were defined on the basis of discrepancies between self-report and physiological measures of stress. As predicted, Ss in the denial group performed better under stress than Ss in the accentuator group, and Ss in the neutral group performed in a manner intermediate between the other 2. Differences between this study and studies in which defensiveness was measured by questionnaires are discussed, as are possible reasons why Ss in the accentuator group seem to be particularly vulnerable to adverse effects of stress.
