时间感知对海洛因成瘾者跨期决策的影响

The Effect of Time Perception on Intertemporal Decision-Making in Heroin Addicts

本研究旨在探讨海洛因成瘾者的时间感知对其跨期决策的影响。研究采用时间估计任务以及跨期决策任务分别对海洛因成瘾组和对照组被试进行施测。结果发现:海洛因成瘾组出现对长时距的低估,且时间估计误差明显大于对照组;海洛因成瘾组的延迟折扣率显著高于对照组;时间感知可以显著预测海洛因成瘾者的跨期决策,而对照组无此效应。本研究从时间感知这一角度入手,在一定程度上解释了海洛因成瘾者跨期决策中的“短视”行为。

The aim of this study was to investigate the effect of heroin addicts'time perception on their intertemporal decision-making.The time estimation task and intertemporal decision task were used to measure the heroin addiction group and control group respectively.The results showed that the heroin addiction group showed an underestimation of the long-time interval,and the time estimation error was significantly larger than that of the control group.The delayed discounting rate in heroin addict group was significantly higher than that in control group.Results showed that time perception can significantly predict intertemporal decision-making in the heroin addict group,but not in the control group.From the perspective of time perception,this study explained the“short-sighted”behavior of heroin addicts in intertemporal decision-making to a certain extent.
