摘要
睡眠剥夺是指由于环境或自身原因无法满足正常睡眠时间的情况。大量实证研究发现,睡眠剥夺会导致个体在风险决策中更倾向于风险寻求,同时也有研究表明睡眠剥夺会导致个体风险规避,而目前尚无统一结论。睡眠剥夺从风险感知、风险容忍、风险决策策略三个方面影响了风险决策,其心理机制可由认知和情绪双路径模型进行解释,且脑神经生理学研究也提供了相关证据。未来的研究应该进一步关注：（1）现实工作生活中的睡眠不足对风险决策的影响;（2）睡眠剥夺影响风险决策的理论模型建构。
Sleep deprivation is a situation of shorter-than-optimal sleep time caused by some environmental or individual reasons. A variety of empirical researches studied the relationship between sleep deprivation and risky choice, but there was an argument about whether sleep deprivation leaded to risk-taking. This paper tried to explore the psychological mechanism between sleep deprivation and risky choice. There are three elements influence risky decision making,（i.e., risk perception, risk tolerance and risk decision strategies）, and its psychological mechanism can be explained by dual-process models of cognition and emotion. Furthermore, neural studies provided evidences to support our conclusion. In the future, on the one hand, because most sleep deprivation studies were examined in laboratory, more researches should be focused on the sleep loss in real life; on the other hand, interaction effect of cognition and emotion should be considered to further complete the theoretical model of sleep deprivation and risky choice.
