| Research Abstract |
Behavioral synchrony is considered as one of the important social foundaiton in humans. I experimentally investigated how similar or different tendency of entrainment to external rhythms in chimpanzees and humans. Using an electric keyboard, chimpanzees were trained to tap two keys alternatively. While their tapping, different external rhythms were palyed as distractor stimuli. The results indicated that spontaneous tendency to synchronize their tapping to auditory rhythms had been already acquired in the common ancestors between chimpanzees and humans.
