The aim of this study was to assess the predictive role of coping related variables (trait emotional intelligence and reinvestment, challenge and threat appraisals and cardiac vagal activity) on cardiac vagal activity and working memory under low pressure (LP) and high pressure (HP) conditions. Participants (n = 49) completed trait questionnaires, the Decision Specific Reinvestment Scale, the Movement Specific Reinvestment Scale and Trait Emotional Intelligence Questionnaire. They realized the automated span task, which tests working memory, under counterbalanced LP and HP conditions. Cardiac vagal activity measurements were taken at rest, task and post task for 5 min, along with self-reported ratings of stress. Upon completion of the task, self-report measures of motivation, stress appraisal, attention and perceived pressure were completed. Current findings suggest cardiac vagal activity at rest can predict cardiac vagal activity under pressure, decision reinvestment influences cardiac vagal activity in cognitive tasks under LP and working memory performance is predicted by task cardiac vagal activity in HP only. These results show the importance of combining both subjective and objective psychophysiological variables in performance prediction and strengthen the need for this approach to be adopted across samples.
本研究的目的是评估应对相关变量（特质情绪智力、再投资、挑战和威胁评估以及心脏迷走神经活动）在低压（LP）和高压（HP）条件下对心脏迷走神经活动和工作记忆的预测作用。参与者（n = 49）完成了特质问卷、决策特定再投资量表、运动特定再投资量表和特质情绪智力量表。他们在平衡的LP和HP条件下完成了测试工作记忆的自动化广度任务。在休息、任务期间和任务后5分钟测量心脏迷走神经活动，并进行自我报告的压力评分。任务完成后，完成了动机、压力评估、注意力和感知压力的自我报告测量。目前的研究结果表明，静息时的心脏迷走神经活动可以预测压力下的心脏迷走神经活动，决策再投资在LP下影响认知任务中的心脏迷走神经活动，而仅在HP下工作记忆表现由任务心脏迷走神经活动预测。这些结果表明在性能预测中结合主观和客观心理生理变量的重要性，并加强了在不同样本中采用这种方法的必要性。
