与外部听觉/视觉事件的稳定同步对于合作行为非常重要，例如在管弦乐队中演奏音乐。增强听觉领域同步的一种方法是在要同步的音调之间插入不同的音调。每隔一个音调或更多音调(1：N敲击)的同步敲击比每个音调(1：1敲击)的变化量小。这种现象被称为“细分利益”，它被解释为细分音调的额外时间参考使同步更稳定。然而，目前还不清楚通过细分刺激序列是否会使视觉运动同步变得更稳定。为了阐明这一点，本研究比较了1：3敲击与三张图片序列，以及1：1敲击与单张图片重复。当抽头间隔(ITI)为1200ms或更大时，无论画面(第一、第二或第三画面)在三画面图案中的位置如何，抽头可变性都显示出细分益处。然而，当ITI为<；1000ms时，细分没有任何显著影响。这些结果表明，细分优势是由于细分刺激提供了额外的时间参考，并且该优势依赖于ITI长度。
Stable synchronization with external auditory/visual events is important for cooperative behavior, such as playing music in an orchestra. One way to enhance synchronization in the auditory domain is by inserting different tones between tones to synchronize. Synchronized tapping for every other tone or more (1: n tapping) is less variable than that for each tone (1:1 tapping). This phenomenon is called the “subdivision benefit,” which is interpreted as that additional temporal references by subdivided tones make synchronization more stable. However, it is unclear whether visuomotor synchronization becomes more stable by subdividing a stimulus sequence. To clarify this, the present study compared 1:3 tapping with a sequence of three-picture patterns and 1:1 tapping with a single picture repetition. When the inter-tap interval (ITI) was 1200 ms or more, the tapping variability showed a subdivision benefit, irrespective of the position of the pictures (1st, 2nd, or 3rd picture) in the three-picture pattern. However, when the ITI was <1000 ms, subdivision did not have any significant effect. These results imply that the subdivision benefit is due to the additional temporal reference provided by the subdivided stimuli, and the benefit depends on the ITI length.
