When three pulses mark two open intervals, the length of the second interval is underestimated when it is longer than the first. This phenomenon is called time-shrinking and found in audition and vision. In the present experiment, we investigated time-shrinking for the tactile modality. Eighteen observers adjusted the length of a comparison interval to match a test interval that was presented alone or with a preceding interval. In the range of test intervals (260 – 580 ms), we found a time-shrinking effect of 30 ms that was not dependent on the difference between the test interval and the preceding interval. This result is relevant for the design of tactons that use rhythm or the interval length between pulses to code information.
