Verbal-autonomic discrepancy scores are used to indicate the difference between physiological and self-reported responses to a stressor, in this study mental workload. Cardiovascular and subjective measures of the subjects were allocated to discrepancy scores, which were associated with both coping with anxiety and achieved performance. The remit was to investigate whether the use of a discrepancy score is justified and whether it serves as an indicator of the foregoing criteria. In the context of performance, an undirected form of discrepancy scores was derived on the basis of studies investigating bodily perception and was proofed to be informative. Furthermore, the benefit of using verbal-autonomic interaction terms as a methodical alternative to discrepancy scores was investigated. For this study, 115 pilot candidates completed a questionnaire assessing their individual coping style. Also, their mental workload was examined by means of subjective measures of workload and arousal on the one hand, and cardiovascular measures in terms of heart rate, heart rate variability, systolic and diastolic blood pressure on the other. Comparisons on the basis of correlation coefficients have shown that discrepancy scores between heart rate and subjective arousal were significantly more related to achieved performance than their individual components. Moreover, regression analyses identified the discrepancy scores between systolic blood pressure and subjective workload or arousal in comparison to their individual components as best significant predictor of avoidant coping. An interaction between systolic blood pressure and subjective workload or arousal could be confirmed only in the context of avoidant coping style. Due to the small effect sizes of all regression models, the use of discrepancy scores still remains doubtful.
