Real models: The limits of behavioural evidence for understanding the ANS

Denitza Dramkin et al. Behav Brain Sci. .

Abstract

Clarke and Beck use behavioural evidence to argue that (1) approximate ratio computations are sufficient for claiming that the approximate number system (ANS) represents the rationals, and (2) the ANS does not represent the reals. We argue that pure behaviour is a poor litmus test for this problem, and that we should trust the psychophysical models that place ANS representations within the reals.
