摘要
Temporal judgments regarding a target interval typically produce a nearly normally distributed reproduction times centered on the target with substantial variance. This phenomenon indicates that the majority of our temporal judgments are deviations from the target times, which are assumed to originate from the underlying timing uncertainty. Although humans were found to adapt their decisions in response to timing uncertainty, we do not know if they can accurately judge the direction and degree of their temporal errors. In this study, we asked participants to reproduce durations as accurately as possible. After each reproduction, participants were asked to retrospectively rate their confidence in their temporal estimates and to judge if their response time was earlier or later than the target interval. The results revealed that human participants are aware of both the direction and magnitude of their timing errors, pointing at an informationally rich temporal error monitoring ability. We further show that a sequential diffusion process can account for the detection of direction of errors as well as the qualitative features of the relationship of objective temporal errors with subjective confidence ratings and associated response times.
