In a Huffington Post article here Tetsuro Matsuzawa a professor in Inuyama, Japan has come to the conclusion after three decades of research chimps have much better short term memory than human beings.  “We’ve concluded through the cognitive tests that chimps have extraordinary memories,” Matsuzawa said.  “They can grasp things at a glance”.  Chimps often need to make quick decisions.  They take multiple factors into consideration. Working memory helps chimpanzees navigate the branches of huge trees to feed.  It also aids them in making tactical decisions when confronted by groups of rival chimps.

Amazing short term memory. With just a quick glance at the computer screen watch ‘Ayumu’ crush this memory test!
