Abstract

The temporal sensitivity for discriminating a gap marked by two tones is affected by the structure of markers. It is known that successive tones are segmented to construct rhythm in perception, and the temporal sensitivity for repeated gaps is changed depending on what rhythmic grouping takes place. The amplitude of each tone rose and decayed during 20 ms at the beginning and the end with raised-cosine ramps. The markers were presented at a level that was 30 dB higher than the threshold level measured before each session. The repetition-pattern phase consisted of two sub-phases for two types of tasks, which were carried out in counterbalanced order. In the gap-following-short-tone task (RS), two repetition patterns were presented successively in each trial, and the second pattern was compared with the first pattern in terms of the gap duration following the short tones.
