In the present research, key variables (i.e., temporal relevance and temporal uncertainty) from models of psychological short-term timing processes are applied to time-based prospective memory in order to investigate if they have an effect on clock checks or ultimate performance in these longer term intentions. Increasing temporal uncertainty resulted in more clock checks in Experiment 1 but this effect was mediated by the effect of temporal relevance in Experiment 2. The latter interaction supports the suggestion that temporal relevance exerts an overpowering effect on attention to time, resulting in a difference in susceptibility to the influence of temporal uncertainty. We discuss these results as they relate to both psychological models of time as well as the tenets of basic models of memory and attention.
