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

In this review, we are pitting two theories against each other: the more accepted theory, the
number sense theory, suggesting that a sense of number is innate and non-symbolic …

We examined relations between symbolic and non-symbolic numerical magnitude
representations, between whole number and fraction representations, and between these …

Many studies tested the association between numerical magnitude processing and
mathematics achievement, but results differ depending on the number format used. For …

Many recent studies have examined the association between number acuity, which is the
ability to rapidly and non-symbolically estimate the quantity of items appearing in a scene …

It is widely accepted that human and nonhuman species possess a specialized system to
process large approximate numerosities. The theory of an evolutionarily ancient …

Math relies on mastery and integration of a wide range of simpler numerical processes and
concepts. Recent work has identified several numerical competencies that predict variation …

The integrated theory of numerical development posits that a central theme of numerical
development from infancy to adulthood is progressive broadening of the types and ranges of …

Recent research reveals a link between individual differences in mathematics achievement
and performance on tasks that activate the approximate number system (ANS): a primitive …

In this study, the performance of typically develo** 6-to 8-year-old children on an
approximate number discrimination task, a symbolic comparison task, and a symbolic and …
