摘要

背景/目的:最近的社会神经科学研究逐渐从个体道德决策转向研究人们如何在人际环境中处理道德困境。本研究通过多方法超扫描研究,探讨了两组道德决策取向的初始差异是否会影响联合道德协商过程中的神经和自主神经同步。方法:根据个体决策取向的相似性或差异性,将14对染色体分为同源或异源。每个小组被要求就涉及现实卫生紧急情况的道德困境进行谈判并达成共同决定。同时记录脑电图和自主神经信号。计算差异性指数来评估脑间和自主神经同步。结果:脑电图分析显示,只有在δ频段有显著的影响:与左颞-中央和右顶-枕区相比,所有双组,无论方向如何,在左额区表现出更大的差异。此外,自主神经数据显示,同系双体的心率变异性(HRV)差异大于异系双体。然而,这些结果并没有证实我们最初的假设,而是表明了相反的模式。结论:左额叶三角洲差异是二代道德协商的探索性候选标记。同源二联体中更大的HRV差异表明,在这些二联体中,成功的协商可能是由互补而不是同步的自主反应支持的。这种多方法超扫描方法强调了神经和自主过程对共同道德决策调节的复杂和部分可分离的贡献。

A BIO-EEG Hyperscanning Study of Moral Dyadic Negotiation.

Background/objectives: Recent social neuroscience research has increasingly shifted from individual moral decision-making to the study of how people negotiate moral dilemmas in interpersonal contexts. This multimethod hyperscanning study investigated whether initial differences in moral decision-making orientation within a dyad influence neural and autonomic synchronization during a joint moral negotiation.

Methods: Fourteen dyads were classified as homologous or heterologous based on the similarity or dissimilarity of their individual decision-making orientations. Each dyad was asked to negotiate and reach a shared decision on a moral dilemma involving a realistic health emergency scenario. Electroencephalography (EEG) and autonomic signals were recorded simultaneously. Dissimilarity indices were computed to assess inter-brain and autonomic synchronization.

Results: EEG analyses revealed a significant effect only in the delta frequency band: all dyads, regardless of orientation, showed greater dissimilarity in the left frontal region compared to the left temporo-central and right parieto-occipital regions. In addition, autonomic data indicated greater heart rate variability (HRV) dissimilarity in homologous dyads than in heterologous ones. However, these results did not confirm our initial hypotheses, indicating the opposite pattern.

Conclusions: Left frontal delta dissimilarity emerged as an exploratory candidate marker of moral negotiation across dyads. Greater HRV dissimilarity in homologous dyads suggests that, in these dyads, successful negotiation may be supported by complementary rather than synchronized autonomic responses. This multimethod hyperscanning approach highlights the complex and partially dissociable contributions of neural and autonomic processes to the regulation of shared moral decision-making.

期刊介绍: Brain Sciences (ISSN 2076-3425) is a peer-reviewed scientific journal that publishes original articles, critical reviews, research notes and short communications in the areas of cognitive neuroscience, developmental neuroscience, molecular and cellular neuroscience, neural engineering, neuroimaging, neurolinguistics, neuropathy, systems neuroscience, and theoretical and computational neuroscience. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files or software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
