突发事件下情绪对决策者风险偏好和框架效应的影响

The Effects of Emotion on Risk Preference and Framing Effect under Emergency

突发事件的严重后果和时间压力易诱发决策者的负性情绪,并在应急决策中产生框架效应,影响决策效果。通过实验诱发150名被试的焦虑和悲伤情绪来探究负性情绪对决策的影响。研究发现:焦虑情绪下的决策者偏好风险规避,悲伤情绪下的决策者偏好风险寻求;悲伤情绪增强了框架效应,焦虑情绪对其无显著影响。结论说明,不应以传统的效价分类而应基于具体情绪考虑情绪对决策的影响,研究还揭示了偏好反转的内在机制,丰富了突发事件下情绪影响决策的理论。

Decision pressure can induce decision makers negative emotion and lead to framing effects under emergency.Moreover,these factors may have negative effect on decision maker＇s performance.In this study,150 subjects were induced with anxiety and sadness in experiment to compare the impact of the two different emotions on decision performance.The research results showed that anxious individuals were biased in favor of risk-averse choice,whereas sad individuals were biased in favor of risk-seeking choice,and distinct emotion led to different framing effects：anxiety amplified the impact of frame,while there was no significant influence for sadness.The results provided evidences that decision-making preferences and framing effects could be affected by specific emotions.Meanwhile research revealed the internal mechanism of preference reversal and enriched the theory of emotion＇s influence on decision-making under emergency.
