居民在新型冠状病毒肺炎疫情期间跨期选择的特点

Characteristics of Residents’ Intertemporal Decision during the Coronavirus Pneumonia Epidemic

摘要: 研究采用跨期决策任务，探讨在新冠肺炎疫情这一特殊大环境下居民跨期选择的特点。结果发现，在非疫情环境中，相对于损失情景居民在收益情景中倾向于选择即时选项；在疫情环境中，居民对于收益损失决策情景之间选择则不存在显著差异。在收益情景中，相对于疫情期间，居民在非疫情期间会偏好即时选项；在损失情景中，疫情非疫情环境选择不存在显著差异。总之，在不同大环境下跨期决策存在显著差异，疫情环境下人在收益时更少选择即时选项，损失时则相反，这可能是疫情引发居民诸多负性心理及创伤体验，使得居民更豁达，面对跨期选择时没有明显的偏向性。

Abstract: The study used an intertemporal decision task to explore the characteristics of residents’ inter-temporal choices in the context of the Coronavirus (COVID-19) pandemic. The results showed that in the non-epidemic environment, residents will prefer the immediate option in the gain scenario relative to the loss scenario; in the epidemic environment, there is no significant difference in residents’ choice between gain-loss decision scenarios. In the gain scenario, residents will prefer the immediate option in the non-epidemic period relative to the epidemic period, while in the loss scenario, there is no significant difference in the choice between the epidemic and non-epidemic environment. In summary, there is a significant difference of people’s decision making between the epidemic and non-epidemic environment. Specifically, people in the epidemic environment are less likely to choose the immediate option during gains and less likely to choose the immediate option during losses. This may be due to the many negative psychological and traumatic experiences triggered by the epidemic, making residents more open-minded and less obviously inclined in the face of interterm choices.
