使用延迟贴现任务和新的自我报告措施，对 935 名 10 至 30 岁个体的样本进行了未来取向的年龄差异检查。与 16 岁及以上的人相比，年轻的青少年始终表现出较弱的未来导向，这反映在他们更愿意接受较早提供的较小奖励，而不是延迟提供的较大奖励，而且他们认为自己不太关心未来，不太可能预测自己决定的后果。相比之下，提前计划会持续发展到成年初期。未来的研究应该区分未来定向和冲动控制，它们可能具有不同的神经基础并遵循不同的发展时间表。
Age differences in future orientation are examined in a sample of 935 individuals between 10 and 30 years using a delay discounting task as well as a new self-report measure. Younger adolescents consistently demonstrate a weaker orientation to the future than do individuals aged 16 and older, as reflected in their greater willingness to accept a smaller reward delivered sooner than a larger one that is delayed, and in their characterizations of themselves as less concerned about the future and less likely to anticipate the consequences of their decisions. Planning ahead, in contrast, continues to develop into young adulthood. Future studies should distinguish between future orientation and impulse control, which may have different neural underpinnings and follow different developmental timetables.
