Minimizing the temporal gap between behavior and reward enhances persistence, but the effect of other outcomes is unknown. Two concurrently run studies aimed to investigate whether persistence on a physical task would be influenced according to whether participants expected immediate versus delayed goal feedback. Furthermore, whether this effect occurs via intrinsic motivation (Studies 1 and 2) or delaying the desire–goal conflict (Study 2) was examined. Using a counterbalanced within-person design, 34 participants in each study (Study 1: 16 males, 18 females; Study 2: 15 males, 19 females) completed two wall-sit persistence tasks, one with immediate feedback expected (regarding the participant’s position on a leader board) and the other with feedback expected to be provided 1 week later. A two-way mixed analysis of variance found no significant differences in persistence between conditions in either study. Furthermore, no indirect effects were found via intrinsic motivation or delayed desire–goal conflict. Study findings did not support the hypothesis that the timing of expected feedback enhances persistence.

最小化行为和奖励之间的时间差距可以增强持久性，但其他结果的影响尚不清楚。两项同时进行的研究旨在调查是否会根据参与者是否期望即时目标反馈或延迟目标反馈来影响对身体任务的坚持。此外，研究了这种影响是通过内在动机（研究 1 和 2）还是延迟欲望-目标冲突（研究 2）发生的。使用平衡的人内设计，每项研究的 34 名参与者（研究 1：16 名男性，18 名女性；研究 2：15 名男性，19 名女性）完成了两项靠墙坐下的持久性任务，其中一项预期会立即得到反馈（关于参与者的位置）在排行榜上）和另一个预计将在 1 周后提供反馈。双向混合方差分析发现，在这两项研究中，条件之间的持久性没有显着差异。此外，没有发现通过内在动机或延迟的欲望-目标冲突产生的间接影响。研究结果不支持预期反馈的时机会增强持久性的假设。
