The aim of this study is to explore the contribution of cardiac vagal activity (CVA), derived from heart rate variability (HRV), on peripheral perception under pressure. Forty-nine participants (n=49) completed a peripheral perception task under pressure. Peripheral perception was measured via the Vienna system from which performance variables were derived (total field of vision, total correct reactions, total incorrect reactions and omitted reactions). CVA measurements were taken at baseline, during the task and post-task for 5min along with subjective self-reported stress ratings on a visual analog scale (VAS). Post-task perceived pressure and motivation measures were taken in order to check for pressure manipulation and motivation to compete. CVA measures were inputted as independent variables into a stepwise liner regression in order to predict peripheral perception performance. Results showed there were no predictors for variables related to peripheral perception performance, indicating that CVA does not significantly affect peripheral perception. Suggestion for null findings is discussed in light of the neurovisceral integration model.
本研究的目的是探讨源自心率变异性（HRV）的心脏迷走神经活动（CVA）在压力下对周围感知的作用。49名参与者（n = 49）在压力下完成了一项周围感知任务。通过维也纳系统测量周围感知，从中得出性能变量（总视野、总正确反应、总错误反应和遗漏反应）。在基线、任务期间和任务后5分钟测量CVA，并使用视觉模拟量表（VAS）进行主观自我报告的压力评分。任务后进行感知压力和动机测量，以检查压力操纵和竞争动机。将CVA测量值作为自变量输入逐步线性回归，以预测周围感知性能。结果表明，没有与周围感知性能相关的变量的预测因子，这表明CVA不会显著影响周围感知。根据神经内脏整合模型讨论了零结果的建议。
