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.

我一直在研究黑猩猩的互动同步性在两种不同的实验设置下：并排和面对面的设置。在本财政年度，我报告了并排设置的结果（Yu & Tomonaga，出版）。这篇论文表明，在实验室环境下，手指敲击任务是研究黑猩猩互动同步的一种潜在方法。考虑到以往的研究大多来自轶事，本研究在方法论上具有重要意义。我继续在面对面的设置下进行实验研究。与并排实验的结果相比，我发现面对面实验中成对黑猩猩的互动同步倾向更强。这表明，同伴动作的听觉和视觉信息对促进黑猩猩的互动同步都很重要。此外，我发现了一个普遍的趋势，即同步的敲击运动发生在每对中至少有一个人的显著敲击变化。这一发现是值得注意的，因为众所周知，人类会以相互的方式将他们的运动结合起来。人类和黑猩猩之间的这种显著差异将帮助我们理解互动同步的进化意义，这是当前研究的目标行为。研究结果在几个会议上发表，包括两个国际会议。
