童年及当前环境压力对跨期选择的影响:时间感知的中介作用

本文分别以90名和70名大学生为被试,通过问卷调查和实验任务的方式,探究童年环境、当前环境压力、时间感知和跨期选择四者之间的关系。结果表明:(1)童年环境影响时间感知,相比童年社会经济地位高的个体,童年社会经济地位低的个体更倾向于高估时距。(2)在正常环境下,个体时间感知完全中介作用于童年环境和跨期选择之间的关系,童年环境通过影响个体时间感知进而影响个体的跨期选择。(3)在当前环境压力下,时间感知并未起到中介作用。研究表明,时间感知在童年压力与在当前环境压力条件下,对跨期选择的影响作用不同。

The Influence of Childhood and Current Environmental Stress on Intertemporal Choice:The Mediating Role of Time Perception

based on the questionnaires and experimental tasks participated by 90 and 70 college students respectively in this investigation,this article explores and studies the relationship among childhood environment,current environmental stress,time perception and intertemporal choice.Results indicated that:(1)compared with the high economic status,low social economic status participants tend to overestimate the time estimation.(2)In normal circumstances,time perception completely mediates the relationship between childhood environment and intertemporal choice.Childhood environment has influences on individual time perception so as to the intertemporal choice.(3)Under the current environmental stress condition,time perception does not play an intermediary role.The results show that under different conditions of childhood stress and current environmental stress time perception has different effects on the intertemporal choice.
