| Research Abstract |
I conducted research on the social interaction accompanied by social conflicts among chimpanzees and among human children. In the investigation of wild chimpanzees, I measured the concentration of cortisol in excrement as a physiological marker of stress. I also analyzed the social interaction between chimpanzee mother and child when a child lost sight of mother. In addition, I examined the cultural aspect in the diversity of the pattern of aggressive behaviors among wild chimpanzees. I also conducted a research on captive chimpanzees, focusing on the reaction to the vocalization from out of sight that occurred during an aggression. Finally, I performed comparison on laughter between chimpanzees and humans, and discussed the aggressiveness of human laughter.
