Foreperiod effect on time estimation and simple reaction time

Abstract

The nature of temporal experience associated with foreperiod duration was studied with respect to verbal estimation and temporal reproduction of stimulus duration, and also simple reaction time. When foreperiod was variable, decrease of foreperiod duration was accompanied by a tendency for relative underestimation of subsequent stimulus duration. Such tendency was eliminated when a relatively shorter foreperiod was presented more frequently than a longer foreperiod. Marked similarity of the effect of foreperiod duration between time estimation and simple reaction time experiments was demonstrated.
