Abstract Number order processing is thought to contribute to arithmetic development.
Although we typically assess order processing using order verification tasks, there is reason …

Digit comparison is strongly related to individual differences in children's arithmetic ability.
Why this is the case, however, remains unclear to date. Therefore, we investigated the …

Ordinal processing plays a fundamental role in both the representation and manipulation of
symbolic numbers. As such, it is important to understand how children come to develop a …

This study tested the hypothesis that individuals with dyscalculia have an order processing
deficit. The ordering measures included both numerical and non-numerical ordering tasks …

There is an ongoing debate concerning how numbers acquire numerical meaning. On the
one hand, it has been argued that symbols acquire meaning via a mapping to external …

Mathematical competencies can be conceptualized as layers of knowledge, with numeracy
skills as the foundational core and more complex mathematical skills as the additional layers …

Ordinality is a fundamental feature of numbers and recent studies have highlighted the role
that number ordering abilities play in mathematical development (eg, Lyons et al.,), as well …

A series of effects characterises the processing of symbolic numbers (ie, distance effect, size
effect, SNARC effect, size congruency effect). The combination of these effects supports the …

Children's knowledge of the ordinal relations among number symbols is related to their
mathematical learning. Ordinal knowledge has been measured using judgment (ie, decide …

Understanding the relationship between symbolic numerical abilities and individual
differences in mathematical competencies has become a central research endeavor in the …
