项目摘要

I have been conducting a study of interactional synchrony in chimpanzees under two different experimental setups: side-by-side and face-to-face setup. In this fiscal year, I reported the findings from the side-by-side setup (Yu & Tomonaga, in press). The paper demonstrated that a finger tapping task is one potential method for investigating interactional synchrony in chimpanzees under a laboratory setting. Considering that the previous studies are mostly from anecdotes, the current study has significance for its methodology.I continued an experimental study under face-to-face setup. In comparison with the findings from the side-by-side setup, I found a stronger tendency of interactional synchrony between pairs of chimpanzees in the face-to-face setup. This suggested that both auditory and visual information of the partner’s movement is important to facilitate interactional synchrony in chimpanzees. Moreover, I found a general tendency that synchronized tapping movement occurs by significant tapping change by at least one individual of each pair. This finding was notable because humans are known to couple their movement in a mutual way. This significant difference between humans and chimpanzees will help us to understand evolutionary significance of interactional synchrony, a target behavior of the current study. The findings were presented in several conferences, including two international conferences.

在两个不同的实验设置下，我一直在研究黑猩猩的交互式同步：并排和面对面的设置。在这个财政年度，我报告了并排设置的发现（Yu＆Tomonaga，印刷中）。该论文表明，手指敲击任务是一种潜在的方法，用于研究实验室环境下黑猩猩的交互式同步。考虑到先前的研究主要来自轶事，当前的研究对其方法具有重要意义。我继续在面对面设置下进行了一项实验研究。与并排设置的发现相比，我发现面对面设置中的黑猩猩对之间的互动同步有很强的趋势。这表明伴侣运动的听觉和视觉信息对于促进黑猩猩的互动同步都很重要。此外，我发现一种普遍的趋势是，同步的敲击运动是通过至少每对的一个个体进行大量攻击变化而发生的。这一发现值得注意，因为众所周知，人类会以一种相互的方式将自己的运动搭配。人类和黑猩猩之间的这种显着差异将有助于我们了解互动同步的进化意义，这是当前研究的目标行为。这些发现是在几个会议上提出的，其中包括两个国际会议。
