A sample of 641 participants were presented with four decision-making tasks during the first stages of the COVID-19 lockdown in Spain: The dictator game, framing problems, utilitarian/deontological and altruistic/egoistic moral dilemmas. Participants also completed questionnaires on mental health status and experiences related to the COVID-19 pandemic. We used boosted regression trees (an advanced form of regression analysis based on machine learning) to model relationships between responses to the questionnaires and decision-making tasks. Results showed that the psychological impact of the COVID-19 pandemic predicted participants' responses to the framing problems and utilitarian/deontological and altruistic/egoistic moral dilemmas (but not to the dictator game). More concretely, the more psychological impact participants suffered, the more they were willing to choose the safest response in the framing problems, and the more deontological/altruistic were their responses to moral dilemmas. These results suggest that the psychological impact of the COVID-19 pandemic might prompt automatic processes.
在西班牙新冠疫情封锁的第一阶段，对641名参与者进行了抽样，让他们完成四项决策任务：独裁者博弈、框架问题、功利主义/道义论以及利他主义/利己主义道德困境。参与者还完成了关于心理健康状况以及与新冠疫情相关经历的问卷调查。我们使用增强回归树（一种基于机器学习的高级回归分析形式）来建立问卷回答与决策任务之间的关系模型。结果显示，新冠疫情的心理影响预测了参与者对框架问题、功利主义/道义论以及利他主义/利己主义道德困境的回答（但对独裁者博弈没有影响）。更具体地说，参与者遭受的心理影响越大，他们在框架问题中就越愿意选择最安全的回答，并且他们在道德困境中的回答就越偏向道义论/利他主义。这些结果表明，新冠疫情的心理影响可能会促使自动过程的发生。
