Future time perspective (FTP) modulates individuals' temporal orientation in selecting their motivations and goals, which widely influences their cognitions and behaviors. However, it remains unclear how FTP exactly affects intertemporal choice. To clarify the effect of FTP on intertemporal choice, 90 college students ( = 21.70, = 1.23) were randomly assigned to the limited FTP condition (16 males, 29 females) and the open-ended FTP condition (17 males, 28 females). In the limited FTP condition, participants were instructed to imagine their states of being 70 years old, whereas in the open-ended FTP condition, they were instructed to describe their current states. All participants then completed a series of intertemporal choice tasks, in which they chose from gain- and loss-related choices occurring at various time points. Results showed that the participants who received the future-imagining manipulation had more limited FTP compared with those who did not receive the manipulation, which confirmed the validity of the FTP manipulation. A 2 (FTP: limited vs. open-ended) × 2 (type of choice: gain vs. loss) repeated measures ANOVA on discount rate revealed a significant interaction between these two factors. The participants in the limited FTP condition had higher discount rates on gain-related choices but showed no difference on loss-related choices compared with the participants under the open-ended FTP condition. The results suggest that limited FTP could lower individuals' future orientation (i.e., willingness to delay an outcome) on gain-related, but not on loss-related, intertemporal decision-making.
未来时间视角(FTP)在个体选择动机和目标时调节其时间取向,这广泛影响着他们的认知和行为。然而,目前尚不清楚FTP究竟如何影响跨期选择。为了阐明FTP对跨期选择的影响,90名大学生(平均年龄 = 21.70岁,标准差 = 1.23)被随机分配到有限FTP条件组(16名男性,29名女性)和开放式FTP条件组(17名男性,28名女性)。在有限FTP条件下,参与者被要求想象自己70岁时的状态,而在开放式FTP条件下,他们被要求描述自己当前的状态。然后,所有参与者完成了一系列跨期选择任务,在这些任务中,他们从不同时间点出现的收益和损失相关选择中进行选择。结果表明,接受未来想象操纵的参与者与未接受操纵的参与者相比,其FTP更有限,这证实了FTP操纵的有效性。对折扣率进行的2(FTP:有限 vs. 开放式)×2(选择类型:收益 vs. 损失)重复测量方差分析显示,这两个因素之间存在显著交互作用。与开放式FTP条件下的参与者相比,有限FTP条件下的参与者在收益相关选择上的折扣率更高,但在损失相关选择上没有差异。结果表明,有限的FTP会降低个体在收益相关而非损失相关的跨期决策中的未来取向(即延迟结果的意愿)。
