The effects of structural predictability on remembered duration judgments were examined within the context of the performance of a series of highly familiar tasks. Across a set of three experiments, task predictability was manipulated by the presence or absence of advance expectancies of what tasks were to be performed (Experiment 1), an (in) variant ordering of task performance (Experiment 2), and the placement of interruptions at between- versus within-task locations (Experiment 3). In each case, a higher degree of predictability led to more accurate and reliable duration estimates that were relatively free of bias, while uncertainty decreased accuracy through an overestimation bias. These results not only render insight into the mediational mechanisms responsible for temporal judgments, but also suggest some practical applications for everyday behavior.
在一系列高度熟悉的任务表现的背景下，研究了结构可预测性对记忆持续时间判断的影响。在一组三个实验中，通过是否存在对要执行的任务的预先预期（实验1）、任务执行的（不）可变顺序（实验2）以及在任务之间与任务内部位置的中断位置（实验3）来操纵任务可预测性。在每种情况下，更高程度的可预测性导致更准确和可靠的持续时间估计，且相对无偏差，而不确定性则通过高估偏差降低了准确性。这些结果不仅有助于深入了解负责时间判断的中介机制，还为日常行为提供了一些实际应用。
