Ratio-based perceptual foundations for rational numbers, and perhaps whole numbers, too?

Edward M Hubbard et al. Behav Brain Sci. .

Abstract

Clarke and Beck suggest that the ratio processing system (RPS) may be a component of the approximate number system (ANS), which they suggest represents rational numbers. We argue that available evidence is inconsistent with their account and advocate for a two-systems view. This implies that there may be many access points for numerical cognition - and that privileging the ANS may be a mistake.
