This study investigated whether an auditory distractor (D) sequence affects the timing of self-paced finger tapping. To begin with, Experiment 1 replicated earlier findings by showing that, when taps are synchronized with an isochronous auditory target (T) sequence, an isochronous D sequence of different tempo and pitch systematically modulates the tap timing. The extent of the modulation depended on the relative intensity of the T and D tones, but not on their pitch distance. Experiment 2 then used a synchronization-continuation paradigm in which D sequences of different tempi were introduced only during continuation tapping. Although the D sequences rarely captured the taps completely, they did increase the tapping variability and deviations from the correct tempo. Furthermore, they eliminated the negative correlation between successive inter-tap intervals and led to intermittent phase locking when the tapping period was close to the period of the D sequence. These distractor effects occurred regardless of whether or not the taps generated auditory feedback tones. The distractor effects thus depend neither on the intention to synchronize with a T sequence nor on the simultaneous perception of two auditory sequences. Rather, they seem to reflect a basic attraction of rhythmic movement to auditory rhythms.
本研究调查了听觉干扰（D）序列是否会影响自主节奏的手指敲击的时间。首先，实验1重复了早期的研究结果，表明当敲击与等时听觉目标（T）序列同步时，不同节奏和音高的等时D序列会系统地调节敲击时间。调节的程度取决于T音和D音的相对强度，而不是它们的音高距离。然后，实验2使用了同步 - 延续范式，其中仅在延续敲击期间引入不同节奏的D序列。虽然D序列很少能完全捕捉到敲击，但它们确实增加了敲击的变异性以及与正确节奏的偏差。此外，它们消除了连续敲击间隔之间的负相关，并在敲击周期接近D序列的周期时导致间歇性锁相。无论敲击是否产生听觉反馈音，这些干扰效应都会出现。因此，干扰效应既不依赖于与T序列同步的意图，也不依赖于对两个听觉序列的同时感知。相反，它们似乎反映了有节奏的运动对听觉节奏的一种基本吸引力。
