中文摘要：
情绪是决策过程中的重要因素,但具体的恐惧情绪对跨期选择决策的影响还缺乏深入研究。在实验中,将大学生被试随机分配到恐惧组和中性组,他们在接受指定的情绪刺激后进行跨期选择,并获得与其偏好兼容的报酬。在此之前,两组被试在无情绪刺激下和虚拟回报条件下完成了同样的跨期选择任务。结果表明：（1）选择的视频能够有效地操纵恐惧情绪;（2）是否有真实回报并不影响被试的跨期选择行为;（3）基于组内和组间的比较都证明恐惧情绪显著地降低了等待的耐心,体现为更高的折现率,意味着恐惧者在获取金钱上更加短视。
英文摘要：
Emotion is important in decision, whereas the effect of specific fear on inter - temporal choices remains unclear. In the experiments, participants were randomly assigned to fear - and neutral - state groups. They have to take inter - temporal choices tasks after stimulated by chosen video clips correspondingly, and then received incentive - compatible rewards. Before, tile stone tasks were completed with no real payoffs and without any emotion inductions. Results showed ： （ 1 ） the chosen video clip could manipulate the emotion of fear; （ 2 ） whether or not provided real incentives had no influences on inter - temporal choices of the participants; （ 3 ） the fear increased impatience in terms of higher discount rates based on both between -and within -subject comparisons, which implied a myopic focus on obtaining money immediately instead of later.
