There is growing research into contributing processes and biological correlates of moral inclinations. Recently, a negative association between utilitarianism and resting heart rate variability (HRV) as an indicator of cardiac vagal tone/parasympathetic activity was reported. We aimed to replicate and extend these findings by additionally investigating the sympathetic parameter electro-dermal activity (EDA), but found no associations in the total sample (N = 157). However, when taking sex and the use of combined oral contraceptives (COC) into account, we found a positive association between HRV and estimated deontology in women using COC and men, while in free cycling women there was a negative association. While no direct replication, our results also point to associations between higher HRV and decreased endorsement of harmful actions that serve a greater good. Unlike HRV, EDA showed no associations with moral judgements. In addition, there were correlations between personality traits and moral judgement.
关于道德倾向的促成过程和生物学关联的研究越来越多。最近，有报道称功利主义与作为心脏迷走神经张力/副交感神经活动指标的静息心率变异性（HRV）之间存在负相关。我们旨在通过额外研究交感神经参数皮肤电活动（EDA）来重复和扩展这些发现，但在总样本（N = 157）中未发现关联。然而，当考虑性别和复方口服避孕药（COC）的使用时，我们发现使用COC的女性和男性的HRV与估计的道义论之间存在正相关，而在自然周期的女性中则存在负相关。虽然没有直接重复，但我们的结果也表明较高的HRV与对为了更大利益而采取的有害行为的认可度降低之间存在关联。与HRV不同，EDA与道德判断没有关联。此外，人格特质与道德判断之间存在相关性。
