Abstract: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.
