项目摘要

In everyday life, moral decisions frequently need to be made under acute stress. Although there is empirical evidence that both stress and stress hormones affect decision-making in various domains including economic, social, and abstract moral decision-making, surprisingly few attempts have been made to explore the effects of stress on everyday moral decision-making. Therefore, the overarching goal of this project is to experimentally investigate the thesis that acute psychosocial stress influences decision-making in everyday moral conflict situations in both men and women.With this application for continuated funding of the proposal (sign removed), we apply for an extension of staff appropriations from 30 to 36 months. The original project comprised two main studies. In a first main experimental laboratory study, we investigated the impact of acute psychosocial stress on everyday moral decision-making applying for the first time a within-subjects design (results available). In a second main experimental study, we aim to examine behavioral effects and, for the first time, neuronal activation patterns during everyday moral decision-making after acute stress exposure using fMRI (data collection still outstanding). For main study 2, an essential prerequisite was the development and establishment of new fMRI compatible paradigms (placebo version of the ScanSTRESS paradigm and moral decision-making paradigm). These new paradigm developments have been successfully accomplished by now. Though, this process turned out to be much more complex (with regard to content as well as technically) and especially more time-consuming than originally planned. Simultaneously to main study 1 and the preparatory works for main study 2, we successfully pursued the following additional research questions: After the development of new stimulus material for both main studies, four independent validation studies have been conducted. This led to the establishment of the EMCS Scale (published in Singer et al., 2019). In an additional behavioral study (between-subjects design), we investigated the time dependency of stress effects on everyday moral decision-making (Singer et al., in preparation). Since the results of main study 1 (within-subjects design) did not confirm the expected stress effects on everyday moral decision-making, we additionally conducted a replication of main study 1 (Singer et al., in preparation). With this application for continuated funding of staff appropriations for 6 months, the still outstanding main study 2 will be conducted.

在日常生活中，道德决策经常需要在急性压力下做出。虽然有经验证据表明，压力和压力激素影响决策在各个领域，包括经济，社会和抽象的道德决策，令人惊讶的是，很少有人尝试探索压力对日常道德决策的影响。因此，本课题的主要目的是通过实验研究急性社会心理压力对男性和女性在日常道德冲突中的决策产生影响的理论。本课题申请继续资助（符号已删除），并申请将工作人员经费从30个月延长至36个月。最初的项目包括两项主要研究。在第一项主要实验室研究中，我们首次采用受试者内设计（结果可用）调查了急性心理社会压力对日常道德决策的影响。在第二个主要的实验研究中，我们的目标是检查行为的影响，并首次使用功能磁共振成像（数据收集仍然悬而未决）在急性应激暴露后的日常道德决策过程中的神经元激活模式。对于主研究2，一个必要的先决条件是开发和建立新的功能磁共振成像兼容的范式（安慰剂版本的ScanSTRESS范式和道德决策范式）。到目前为止，这些新的范式发展已经成功完成。然而，这一过程比原计划复杂得多（在内容和技术方面），特别是更耗时。同时，主要研究1和主要研究2的准备工作，我们成功地进行了以下额外的研究问题：两个主要研究的新刺激材料的开发后，四个独立的验证研究已经进行。这导致了EMCS量表的建立（发表在Singer等人，2019年）。在另一项行为研究（受试者间设计）中，我们调查了压力对日常道德决策的影响的时间依赖性（Singer et al.，准备中）。由于主要研究1的结果（受试者内设计）没有证实对日常道德决策的预期压力影响，我们另外进行了主要研究1的复制（Singer et al.，准备中）。在申请继续为工作人员拨款供资6个月后，将开展尚未完成的主要研究2。
