Abstract

The two kinds of tapping tasks were used to investigate the characteristics of the internal process which underlay performance in each of a temporal tracking behavior and a time perception task. One was the synchronization task and the other was the task which required subject to tap evenly in such a way that every third response coincided with each of buzzers. In this one-third tapping task, the relation between SD of reproduced intervals and one-third of an inerval was a steplike function. The value of SD increased in accordance with a multiplying rule (25, 50, 100, or 200ms in the first session, and 25ms or 75ms in the second and third sessions). These results are similar to those of duration discrimination task in time perception. The internal process can be thought of as having a numerical processor which encodes a stimulus duration to the number of units. The relationship between Weber's law and this processor is also discussed.
