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 …

de Hevia and Spelke (de Hevia and Spelke (2009). Spontaneous mapping of number and
space in adults and young children, Cognition, 110, 198–207) investigated the mapping of …

Converging lines of evidence suggest that the numerical abilities in Humans are rooted in
the approximate number system (ANS): an innate, non-verbal mechanism that enables to …

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 …

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 …

Previous studies have demonstrated existence of a mental line for symbolic numbers (eg,
Arabic digits). For nonsymbolic number systems, however, it remains unresolved whether a …

Can physical size affect number estimation? Previous studies have shown that physical size
influences non-symbolic numerosity in comparison tasks (eg which of two dots is larger) …

Studies investigating nonsymbolic numbers (eg, dot arrays) are confronted with the problem
that changes in numerosity are always accompanied by changes in the visual properties of …

In numerical cognition research, it has traditionally been argued that the processing of
symbolic numerals (eg, digits) is identical to the processing of the non-symbolic …

Number-to-space mapping and its directionality are compelling topics in the study of
numerical cognition. Usually, literacy and math education are thought to shape a left-to-right …
