中文摘要：

本研究探讨心理疲劳对风险决策的影响，以及任务框架对这一关系的调节作用。研究采用2（疲劳.非疲劳）X2（获益框架.损失框架）被试问设计，实验纽接受心理疲劳诱导后完成风险决策任务，控制组直接完成风险决策任务。方差分析结果显示，相对于非心理疲劳组，心理疲劳状态下个体更倾向于风险规避，且不受任务框架的影响。

英文摘要：

The purpose of the current study was to explore the effect of mental fatigue level and framing on risk decision making. A 2（fatigue, non-fatigue）x2 （gain frame, loss frame） experiment was designed. A total of 36 undergraduate students accepted fatigue inducement simultaneously. Another 93 undergraduate students finished risk decision making task under non-fatigue status. ANCOVA analysis showed that, participants under fatigue status were more risk averse than those in non-fatigue group. The main effect of framing was significant, but the interaction effect of fatigue level and framing was not significant. The implications of the study and possible future research were discussed.
