| Abstract: | Temporal discounting is a psychological phenomenon which the value of event decreases as time , it’s the important component of behavioral choice theory. The property and mechanism of temporal discounting is reviewed. The attention is concentrate on the function of temporal discounting which display the process of its value discount with the time (exponential function ,hyperbolic function, and q- exponential function), the relation of the temporal discounting and the probability discounting, theory of delayed and accelerated temporal discounting and discussion on neural mechanism about temporal discounting. Some problems in the future researches are proposed |

| Keywords: | temporal discounting temporal discounting function probability discounting delay consumption and accelerate consumption neural mechanism |
