Making and sticking to a decision are two important stages in decision behavior. Intertemporal choice stems from economic research on the process of adults choosing among outcomes at different points in time, whereas delay of gratification comes from psychological research on childhood persistence, in which children had to resist the temptation of the sooner but smaller reward to obtain the later but larger reward. Both studies relate to time and focus on individual impulsiveness and self-control, although from different perspectives. Nonetheless, the two areas are rarely compared systematically. The article addresses this issue and compares their methods as well as their cognitive and neural mechanisms. The article provides scientific theoretical foundations for the collaborative development of both areas to facilitate the practice of foresight.
