    Our aim in this study was to examine the influence of sound-marker durations on the perception of simple rhythm patterns. These comprised three successive sounds marking two neighbouring time intervals, T1 and T2, with their onsets. We varied the durations of each of the three sound markers to make them either 20 or 60 ms. Durations of T1 and T2 were also varied, but the total duration of T1 and T2 was fixed at either 240 or 480 ms. In experiment 1, partic- ipants compared the durations of T1 and T2. In experiment 2, the subjective duration of each interval was measured separately. We found that lengthening the duration of the sound marker which terminated an interval increased the subjective duration of that interval: lengthening the duration of the second marker increased the subjective duration of T1, and lengthening the dura- tion of the third marker increased the subjective duration of T2. Lengthening the duration of the first marker increased the subjective duration of T1 when T1 + T2 = 240 ms, especially when T1 > T2. This effect of first-marker duration, which could not be observed with single intervals used in the control conditions, seemed to enhance the contrast between T1 and T2. The effects of marker durations are associated with previous time-perception studies, in which single time intervals were used. They are discussed in the context of rhythm-perception studies, in which more complex sound patterns have been used.
