"Exact and Approximative Arithmetic in an Amazonian Indigene Group"

Abstract : Is calculation possible without language ? Or is the human ability for arithmetic dependent on the language faculty ? To clarify the relation between language and arithmetic, we studied numerical cognition in speakers of munduruku, an Amazonian language with a very small lexicon of numbers words. Our results imply a distinction between a non-verbal system of number approximation and a language-based counting system for exact number and arithmetic.
