Ayumu (born 24 April 2000) [1] is a chimpanzee currently living at the Primate Research Institute of Kyoto University. He is the son of chimpanzee Ai and has been a participant since infancy in the Ai Project, an ongoing research effort aimed at understanding chimpanzee cognition. [2] As part of the Ai Project, Ayumu participated in a series of short-term memory tasks, such as to remember the sequential order of numbers [3] displaying on a touch-sensitive computer screen. [4] His performance in the tasks was superior to that of comparably trained university students, leading to a possible conclusion that young chimpanzees have better working memory than adult humans. [5] This conclusion has been disputed. [6]
