Task predictability and remembered duration.
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.
