Predictors of Middle School Students’ Growth in Symbolic Number Comparison Performance
Journal of Numerical Cognition, 2022 The ability to efficiently compare number symbols, such as digits, is associated with mathematics competence across the lifespan. Performance on symbolic number comparison tasks differ across age groups; young students who are developing fluency with ...

On the indicators for perceiving empty sets as zero
Acta Psychologica, 2021 The question whether human beings process empty sets as zero has received little research attention. In this study, we used the distance and end effects as indicators for treating empty sets as a numerical entity that represents an absence of quantity ...

Cognitive mediators of US-China differences in early symbolic arithmetic.
PLoS ONE, 2021 Chinese children routinely outperform American peers in standardized tests of mathematics knowledge. To examine mediators of this effect, 95 Chinese and US 5-year-olds completed a test of overall symbolic arithmetic, an IQ subtest, and three tests each ...

Sex differences and functional hemispheric asymmetries during number comparison
Biology of Sex Differences, 2018 Background Global-local stimuli are hierarchical structures consisting of a larger global structure which is composed of smaller local stimuli. Numbers are also constructed hierarchically, with multi-digit numbers being made up from single digits. During

Do We Have a Sense for Irrational Numbers?
Journal of Numerical Cognition, 2017 Number sense requires, at least, an ability to assess magnitude information represented by number symbols. Most educated adults are able to assess magnitude information of rational numbers fairly quickly, including whole numbers and fractions.

Frontiers in Psychology, 2016 Symbolic numerical magnitude processing skills are assumed to be fundamental to arithmetic learning. It is, however, still an open question whether better arithmetic skills are reflected in symbolic numerical magnitude processing skills.

Object-based neglect in number processing
Behavioral and Brain Functions, 2013 Recent evidence suggests that neglect patients seem to have particular problems representing relatively smaller numbers corresponding to the left part of the mental number line.

Frontiers in Psychology, 2018 The respective roles of the approximate number system (ANS) and an access deficit (AD) in developmental dyscalculia (DD) are not well-known. Most studies rely on response times (RTs) or accuracy (error rates) separately.

Using Floating-Point Intervals for Non-Modular Computations in Residue Number System
IEEE Access, 2020 The residue number system (RNS) provides parallel, carry-free, and high-speed arithmetic and is therefore a good tool for high-performance computing. However, operations such as magnitude comparison, sign computation, overflow detection, scaling, and ...
