Many studies have investigated the association between numerical magnitude processing
skills, as assessed by the numerical magnitude comparison task, and broader mathematical …

Background: Arithmetical skills are essential to the effective exercise of citizenship in a
numerate society. How these skills are acquired, or fail to be acquired, is of great importance …

Developmental dyscalculia (DD) is a pervasive difficulty affecting number processing and
arithmetic. It is encountered in around 6% of school-aged children. While previous studies …

The association of enumeration and number comparison capacities with arithmetical
competence was examined in a large sample of children from 2nd to 9th grades. It was …

This study traces developmental changes in automatic and intentional processing of Arabic
numerals using a numerical-Stroop paradigm. In Study 1, university students compared the …

A range of possible predictors of arithmetic and reading were assessed in a large sample
(N= 162) of children between ages 7 years 5 months and 10 years 4 months. A confirmatory …

In 4 experiments, the authors explored the role of visual layout in rule-based syntactic
judgments. Participants judged the validity of a set of algebraic equations that tested their …

To account for the size effect in numerical comparison, three assumptions about the internal
structure of the mental number line (eg, Dehaene, 1992) have been proposed. These are …

Since the original description of Gerstmann's syndrome with its four cardinal symptoms,
among which are finger agnosia and acalculia, the neuro-cognitive relationship between …

Despite the fact that number deficits are as prevalent as literacy deficits, research on basic
numerical skills lags seriously behind the successful studies identifying low-level deficits in …
