Reliability of Time Estimation by the Method of Reproduction

Abstract
A procedure is described which involves the reproduction of the duration of auditory stimuli by a horizontal movement of S's arm. For stimulus durations between 0.9 sec. and 16.0 sec. a mean reliability (product-moment r) of .67 was obtained for judgments of duration, which is rather higher than usual for time judgments by the method of reproduction. Measures of speed of movement yielded a mean reliability of .70. Reproduction of durations by horizontal movements was however less accurate than by pressing down a key.
