【摘要】：跨期选择需要决策者对未来不同时间点的损益之间做出权衡与取舍,涉及对未来时间的长度知觉。本研究认为:在现实生活中,当人们用周期把一段连续的时间分割成不同的部分时(比如把未来的时间划分成本周和下周),他们对未来时间的长度知觉就会发生变化,进而影响跨期选择。实验1控制配对跨期选项的客观间隔时间不变,发现相对于两个奖励选项在同一周期的条件(比如同周),选项分布于不同周期时(比如跨周)被试更愿意选择结果小而早的选项(smaller and sooner,SS)而非结果大而迟的选项(later and larger,LL)。实验2的结果则显示,跨时间周期现象是由于周期分割点的存在,引起被试对选项间的时间间隔知觉变长,进而选择SS所致。
[Abstract]:Intertemporal selection requires decision makers to make trade-offs and trade-offs between future gains and losses at different points in time, involving perception of the length of future time. When people divide a continuous period of time into different parts with cycles (such as dividing future times into this week and next week), their perception of the length of future time changes. Experiment 1 controls that the objective interval between pairs of intertemporal options remains unchanged. It was found that compared to the condition that two reward options were in the same cycle (for example, the same week), the participants were more willing to choose the smaller and option than the large one later when the options were distributed in different cycles (such as the trans-weekly). The results of experiment 2 showed that, The phenomenon of cross-time period is caused by the existence of periodic segmentation points, which leads to the longer time interval between options and the selection of SS.
