More on arithmetic in the Amazon The 10/15 issue of Science has the official publication of Peter Gordon's work on numerical cognition among the Pirahã, and a companion article by Pierre Pica et al. on similar research among another Amazonian tribe, the Mundurukú. What with the U.S. election and the discovery of H. Floresiensis, this is not getting nearly as a much play as the pre-publication back in August of Peter Gordon's work. Brian Butterworth has an piece in the Guardian about both articles, and I've put some links, quotes and diagrams here. Compared to the reports on the Pirahã, the Mundurukú people, language, and experiments are all somewhat different, although the conclusions are broadly similar.

"Uncontacted" tribe contacted in Javari region of Amazon
