Both resting high-frequency heart rate variability (HF-HRV) and executive functioning (EF) are individual differences implicated in vulnerability to a wide range of adverse outcomes. The overlapping set of associations, along with theoretical models positing connections between the brain regions subserving the executive functions and the parasympathetic nervous system, suggest that the two factors should be correlated. Seeking to address limitations in prior research, the current study examined the association between EF, measured comprehensively with individually-administered neuropsychological tests and controlling for lower-order cognitive processes, and resting physiology, measured with impedence cardiography, in healthy, community participants (68% female; mean age = 27, SD = 6.5). Results confirmed a significant association between EF and resting HF-HRV, but no association with resting state sympathetic nervous system activation (pre-ejection period). These findings may inform future investigation of transdiagnostic mechanisms related to these two individual difference factors.
静息高频心率变异性（HF-HRV）和执行功能（EF）均为个体差异，与广泛的不良后果易感性有关。重叠的关联集，以及理论模型假设执行功能和副交感神经系统所服务的大脑区域之间的联系，表明这两个因素应该相关。为了解决先前研究中的局限性，本研究使用阻抗心动描记术测量的静息生理（控制较低阶认知过程），在健康的社区参与者中，全面检查了与执行功能（用个体神经心理测试测量）之间的关联（女性占 68%；平均年龄为 27 岁，标准差为 6.5 岁）。结果证实了 EF 与静息 HF-HRV 之间存在显著关联，但与静息状态交感神经系统激活（射血前期）无关。这些发现可能为未来与这两个个体差异因素相关的跨诊断机制的研究提供信息。
