Time Estimation: Dependence and Independence of Modality-Specific Effects

Abstract

80 Ss were required to reproduce 9 time intervals, ranging from 1 to 17 sec. duration, under 8 experimental conditions: the factorial arrangement of auditory and visual interval presentation, auditory and visual interval reproduction, and patterned and unpatterned stimulus filling the interval. Mode of stimulus presentation and of reproduction had no consistent effect on time estimation. Significant modifications occurred with repeated trials and reliabilities of duration estimations were consistently high.
