霊長類における任意慣習と意思疎通ジェスチャーの文化的伝達

点击翻译按钮获取中文摘要

Within the last fiscal year I have carried out a complete experimental study investigating cultural transmission of an arbitrary gesture in Japanese macaques using the group diffusion paradigm. I also collected data regarding the observation of a Japanese macaque carrying her dead infant for an unusually long period, followed by mother-infant cannibalism. I will present the findings of both studies at an International conference, this summer, and will write them up as an original research article and an observational case study, respectively, for submission to journals. The JSPS grant has enabled me to collaborate with Japanese researchers. I plan to attempt to carry out a survey of potentially cultural behaviours across Japanese macaques in Japan.
