Abstract

We examined whether the duration of two successive short sounds can affect the perception of the time interval marked by the onsets of these sounds. An experiment was conducted using marker durations of 20 to 100 ms and inter-onset time intervals of 120, 240, and 360 ms. The effects of marker duration were summarized as follows: 1) Lengthening both the first and the second marker clearly causes the interval to be judged longer, 2) Lengthening the first marker tends to cause the interval to be judged longer, and 3) Lengthening the second marker also tends to cause the interval to be judged longer.
