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. - show_munduruku_fit.py: produces Munduruku figure. - show_need_probability.py: produces need probability graph. - aggregate_complexities_and_costs.py: produces main complexity/cost tradeoff figure. Can swap in different need distributions from data folder. - get_base_n_complexity.py: plot complexities for a range of recursive bases.
