The present study examined the power of endings on risky decision making. With four experiments, the changes in the individuals' risk-taking tendencies were examined as the end of an investment decision task approached; the role of motivational shift toward emotional satisfaction in the ending effect was also explored. As predicted, participants who knew they were working on the last round of an investment task were more risk seeking than those who did not know (i.e., ending effect, Experiment 1). Experiments 2 through 4 examined the motivational mechanism of the ending effect. The results supported the notion that the motivation to pursue an emotionally rewarding ending leads to the ending effect. The present research complements existing motivational accounts of risk taking and suggests a new research direction of integrating factors associated with time perception of an approaching ending into existing models of risky decision making.
本研究考察了结局对风险决策的影响。通过四个实验，我们研究了当投资决策任务接近尾声时，个体风险偏好倾向的变化；同时还探讨了朝着情感满足的动机转变在结局效应中的作用。正如预测的那样，知道自己正在进行最后一轮投资任务的参与者比不知道的参与者更倾向于冒险（即结局效应，实验 1）。实验 2 到 4 检验了结局效应的动机机制。结果支持了这样一种观点，即追求情感回报的动机导致了结局效应。本研究补充了现有关于风险承担的动机解释，并提出了一个新的研究方向，即将与接近结束的时间感知相关的因素纳入现有的风险决策模型。
