Studies of human adults, infants, and non-human animals demonstrate that non-symbolic
numerical cognition is supported by at least two distinct cognitive systems: a “parallel …

The view that representations of symbolic and nonsymbolic numbers are closely tied to one
another is widespread. However, the link between symbolic and nonsymbolic numbers is …

Cognitive models of magnitude representation are mostly based on the results of studies
that use a magnitude comparison task. These studies show similar distance or ratio effects in …

In line bisection tasks, adults and children bisect towards the numerically larger of two
nonsymbolic numerosities [de Hevia, MD, & Spelke, ES (2009). Spontaneous mapping of …

People use mental number lines for both symbolic numerals and numerosity, but little is
known about how these two mental number lines are related. The current study investigated …

Nonsymbolic comparison tasks are commonly used to index the acuity of an individual's
Approximate Number System (ANS), a cognitive mechanism believed to be involved in the …

A genuinely abstract number representation is thought to be capable of representing the
numerosity of any set of discrete elements, whether they are sequentially or simultaneously …

Previous findings suggest that mentally representing exact numbers larger than four
depends on a verbal count routine (eg,“one, two, three...”). However, these findings are …

The ANS theory on the processing of non-symbolic numerosities and the ANS mapping
account on the processing of symbolic numbers have been the most popular theories on …

Recent years have witnessed an enormous increase in behavioral and neuroimaging
studies of numerical cognition. Particular interest has been devoted toward unraveling …
