    报告摘要: People often choose more desirable future rewards over less desirable immediate ones, but then abandon that choice before the future reward arrives. Examples range from the mundane, such as leaving a bus stop and paying for a cab instead, to the more consequential, such quitting smoking but then relapsing or not sticking with most new year's resolutions. Psychologists often explain such behavior by reference to fundamental limitations in human cognitive systems, such as limited willpower or self-control. I will argue for an alternative explanation that places this behavior within the same general framework widely used to explain decisions from the perceptual to the economic, in which the failure to maintain delay of gratification arises from a rational reevaluation process regarding uncertain delayed outcomes. I will present theoretical, behavioral, and neural evidence in support of such a 'value-based' account of delay of gratification.”
