本研究通过四个实验考察了任务差异对时距判断的影响。实验1和2使用的方法，在前瞻性的，内科目的设计，他们的结果支持以前的研究任务难度的影响这两个实验，使用不同的任务，沿着有点不同的尺寸，发现受试者提供的再现值与任务难度成反比。也就是说，虽然受试者倾向于在所有任务中再现不足，但在目标时间间隔内执行的任务越困难，再现不足的程度就越大。实验3和4使用了一种修改的再现方法，在每个试验的目标间隔和再现阶段对受试者提出要求;他们证明，在目标间隔期间执行的任务和再现期间所做的任务之间的对比度越大，持续时间再现的准确性就越低。结果进行了讨论的上下文和资源分配模型的持续时间估计。
Four experiments were performed to assess the effects of task differences on duration judgments. Experiments 1 and 2 used the method of reproduction in prospective, within-subjects designs; their results supported previous research on the effects of task difficulty Both experiments, using tasks that varied along somewhat different dimensions, found that subjects provided reproduction values that varied inversely with task difficulty. That is, while subjects tended to underreproduce across ah tasks, the more difficult the task performed during the target interval, the greater the extent of the underreproduction. Experiments 3 and 4 used a modification of the reproduction method by placing demands upon the subjects during both the target interval and the reproduction phase of each trial; they demonstrated that the greater the degree of contrast between demands made by the task performed during the target interval and those made during reproduction, the less accurate the duration reproduction. The results are discussed in terms of the contextual and resource allocation models of duration estimation.
