Tetsuro Matsuzawa
Tetsuro Matsuzawa is a former Director of the Primate Research Institute of Kyoto University, Japan. He is currently the Academic Advisor of Chubu Gakuin University, Japan, the Visitor in Psychology at California Institute of Technology, the USA, and the Invited professor of Northwest University in Xi'an, China. Matsuzawa studies chimpanzee intelligence both in the laboratory and in the wild. His laboratory work is known as "Ai project". Since 1977, it focuses on the language-like skills, the concept of number, and the working memory: The participants are a 47-year-old female chimpanzee named Ai, and her 24 year-old son named Ayumu, and others live in the community of 11 chimpanzees including 3 generations. The working memory of young chimpanzees can be better than humans (https://www.youtube.com/watch?v=ktkjUjcZid0). The fact led him to the "Cognitive Tradeoff Hypothesis". In his parallel effort, Matsuzawa has also studied wild chimpanzees at Bossou and Nimba, Republic of Guinea, West Africa, since 1986. The Bossou chimpanzees are known to use a pair of stones as hammer and anvil to crack open oil-palm nuts. His long-term research revealed the topics like the 100% lateralization of handedness of using a stone hammer, the critical period of learning nut-cracking at the age 3 to 5, and the social learning called "Education by Master-Apprenticeship", grand-mothering in chimpanzees, etc. Matsuzawa tries to synthesize the field work and the laboratory work to understand the mind of chimpanzees, our evolutionary neighbors. He has received several prizes including the Purple Ribbon Medal of Honor, the Jane Goodall Award, Person of Cultural Merit, Japan. He has published many articles and books such as Primate Origins of Human Cognition and Behavior (Springer, 2001), Cognitive Development in Chimpanzees (Springer, 2006), The Mind of the Chimpanzee (Chicago University Press, 2010), and Chimpanzees of Bossou and Nimba (Springer, 2011).
