Studies on intertemporal decision-making show that there are significant differences in intertemporal decision-making behavior between positive emotion and negative emotion. From the perspective of single dimension priority model, this study reveals the process mechanism of the influence of emotion on intertemporal decision-making. In Experiment 1, by inducing positive and negative emotions of the participants, we found that the time discount rate of the participants under positive emotions was lower, and they had a stronger tendency to choose delayed options. In Experiment 2, the “visual analog scale task” was used to measure the comparison of inter-dimensional differences in intertemporal decision-making, and to test the explanatory effect of single dimension priority model on intertemporal decision-making. The results showed that the comparison of differences between dimensions plays a mediating role in the influence of emotion on intertemporal decision-making. Experiments 3a and 3b used time and money priming strategies to manipulate the comparison of inter-dimensional differences, and verified the explanatory effect of the single dimension priority model again. The results showed that the effect of emotion on intertemporal decision-making disappears with the initiation of time and money, which further supports the mediating effect of difference comparison between dimensions. From the perspective of decision-making process, this study reveals the psychological mechanism of emotion affecting intertemporal decision-making, and further adds supporting evidence for the explanation of intertemporal decision-making behavior by single dimension priority model.

Key words: intertemporal decision making, positive emotions, negative emotions, comparison of inter-dimensional differences
