Data and code from this repository replicate work in the following publication: Xu, Y., Liu, E., and Regier, T. (in press) Numeral systems across languages support efficient communication: From approximate numerosity to recursion. *Open Mind: Discoveries in Cognitive Science*. - /data: contains need probabilities for languages included in the study. Munduruku data is from Pica, 2004. - produces Munduruku figure. - produces need probability graph. - produces main complexity/cost tradeoff figure. Can swap in different need distributions from data folder. - plot complexities for a range of recursive bases.
