中文摘要：

研究考察了先前情绪和过度自信对灾难事件后继风险决策的影响。结果发现：（1）先前情绪的主效应显著, 积极情绪比消极情绪的个体在灾后风险决策时更加倾向于风险寻求；过度自信的主效应显著, 高过度自信比低过度自信个体在灾后风险决策时更加倾向于风险寻求。（2）先前情绪和过度自信水平交互影响灾难事件后继风险决策。高过度自信者在积极情绪状态下比在消极情绪状态下更倾向于风险寻求; 消极情绪状态下过度自信水平不同的个体之间没有显著差异。

英文摘要：

According to the cognitive neuroeconomic model, emotion and cognition are the important factors affecting risk decision-making following a disaster event. Previous emotion and overconfidence are the emotion and cognition factors influencing risk decision-making following disaster event. Do previous mood and overconfidence affect risk decision-making following a disaster event separately, or influence risk decision-making following disaster event jointly.？ The answer is still unclear in previous studies. Purposes ： The study explored the effect of previous emotion and overconfidence on risk decision-making following a disaster event. Procedures ＆ Methods： Firstly, 200 undergraduates were measured by using overconfidence questionnaire. 40 undergraduates were chosen as high overconfidence individuals because their overconfidence scores were higher than or equal to 35 points, and 40 undergraduates were chosen as low overconfidence individuals because their overconfidence scores were lower than or equal to 20 points. Thus, 80 subjects were obtained in the formal experiment. In the formal experiment, 20 high overconfidence and 20 low overconfident subjects were selected randomly to participate in the experiment of the positive emotional group, while the remaining 20 high overconfidence individuals and 20 low overconfidence subjects took part in the negative emotional group experiment. All formal experiment subjects had to complete the emotion self-rating scale and risk decision-making questionnaire following the disaster. Results ＆ Conclusions： The results showed that （ 1 ） Positive and negative emotions video induced the emotions the experiment required. （2） The main effect of the previous emotion was significant, and risk decision-making individuals under positive emotion were more likely to seek risks than those under negative emotion. The research outcome further supported the affective generalization hypothe- sis （Johnson, ＆ Tversky, 1983 ）. Positive emotion led to a significant indivi
