先前的研究表明，不同的心血管模式与参与者群体的威胁和挑战评估相关。我们通过评估随着评估的变化，评估是否继续与个体内的这些心血管反应模式相关，来扩展这些结果。参与者完成了四项口头心算任务，并在每项任务之前和之后进行了评估。计算每项任务第一分钟和最后一分钟的心脏反应性和总外周阻力（TPR），并测量每项任务的响应数量和正确百分比。根据我们的预测，任务前评估与四项任务中一些与任务相关的心脏反应有关。此外，与任务相关的心血管反应和行为都会影响任务后的评估。我们的研究结果表明，对评估、心血管生理学和任务相关行为进行具体分析可以更丰富地理解评估过程，并揭示值得进一步评估的性别差异。
Previous studies demonstrated distinct cardiovascular patterns associated with threat and challenge appraisals for groups of participants. We extend these results by assessing whether appraisals continue to be associated with these cardiovascular response patterns within an individual as appraisals change. Participants completed four verbal mental arithmetic tasks for which they made appraisals before and after each task. Cardiac reactivity and total peripheral resistance (TPR) were calculated for the first and last minutes of each task, and the number of responses and percent correct were measured for each task. In line with our prediction, pretask appraisals were related to some task-related cardiac responses across the four tasks. In addition, task-related cardiovascular reactivity and behaviors both influenced appraisals following the task. Our findings suggest that an idiographic analysis of appraisals, cardiovascular physiology, and task-related behaviors provides a richer understanding of the appraisal process and reveals sex differences deserving further assessment.
