Delay discounting refers to the decline in the value of a payoff as the objective delay to its fulfillment increases. Recent research on delay discounting has examined its relationship with time and risk perceptions through correlational studies. Manipulated experiments were conducted in the current research to further investigate the causal links among the relevant variables. Experiment 1 revealed causal influences of objective delay on both risk perception and delay discounting as well as a positive correlation between risk perception and delay discounting. By manipulating risk perception, Experiment 2 demonstrated further a causal impact of risk perception on delay discounting. Experiment 3 manipulated time perception and provided further evidence for causal pathways from time perception to risk perception and delay discounting. Overall, the results verified a causal chain from objective delay to delay discounting through time and risk perceptions in support of the implicit-risk hypothesis regarding delay discounting.

延迟贴现是指随着实现的客观延迟增加，收益的价值下降。最近关于延迟贴现的研究通过相关性研究检验了它与时间和风险感知的关系。在当前的研究中进行了操纵实​​验，以进一步研究相关变量之间的因果关系。实验 1 揭示了客观延迟对风险感知和延迟贴现的因果影响，以及风险感知和延迟贴现之间的正相关。通过操纵风险感知，实验 2 进一步证明了风险感知对延迟贴现的因果影响。实验 3 操纵了时间知觉，并为从时间知觉到风险知觉和延迟贴现的因果路径提供了进一步的证据。总体，
