With the global aging population, an increasing number of researchers are interested in the intertemporal choice issues faced by older adults. Previous studies have examined how age-related differences in time perception affect intertemporal choices. However, the impact of time perception strategy on intertemporal decision-making among older adults remains unclear. This study was designed to examine how timing perception strategy influence decision-making among older adults while also exploring the possible mechanisms. We manipulated timing perception strategy preferences through priming in two experiments (Experiment 1,
