Concurrent Processing Demands and the Experience of Time-in-Passing

Abstract

Under the prospective paradigm, judged time decreased monotonically with the increased processing demands of concurrent card sorting (Experiment I) and of concurrent verbal rehearsal (Experiment II). It was nonmonotonically related to concurrent tapping rate (Experiment III), which latter, when required during verbal rehearsal, had an identical curvilinear effect on short-term recall (Experiment IV). It is concluded that the experience of time-in-passing is an inverse function of the processing demanded by a concurrent task. An attentional model is suggested and evaluated against the literature.
