Rathé, Sanne; Torbeyns, Joke; Smedt, Bert De; Verschaffel, Lieven – Mathematical Thinking and Learning: An International Journal, 2022
Children's spontaneous focusing on Arabic number symbols (SFONS) has been identified as a relevant component of their early mathematical development. This study investigated whether SFONS is a separate construct from spontaneous focusing on numerosity (SFON) and examined whether it is uniquely related to numerical abilities and mathematics…

Rathé, Sanne; Torbeyns, Joke; De Smedt, Bert; Verschaffel, Lieven – Mathematical Thinking and Learning: An International Journal, 2020
Children's spontaneous focusing on Arabic number symbols (SFONS) has been identified as a relevant component of their early mathematical development. This study investigated whether SFONS is a separate construct from spontaneous focusing on numerosity (SFON) and examined whether it is uniquely related to numerical abilities and mathematics…

Bakker, Merel; Pelgrims, Elise; Torbeyns, Joke; Verschaffel, Lieven; De Smedt, Bert – Journal of Numerical Cognition, 2023
While symbolic number processing is an important correlate for typical and low mathematics achievement, it remains to be determined whether children with high mathematics achievement also have excellent symbolic number processing abilities. We investigated this question in 64 children (aged 8 to 10), i.e., 32 children with persistent high…

Rathé, Sanne; Torbeyns, Joke; De Smedt, Bert; Verschaffel, Lieven – Journal of Educational Psychology, 2022
This longitudinal cross-lagged panel study investigated the development of the structure of young children's spontaneous number focusing tendencies and their longitudinal associations with numerical abilities and mathematics achievement over the course of a 3-year period, that is, in the second and third year of kindergarten and in first grade of…

Salvaggio, Samuel; Masson, Nicolas; Andres, Michael – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2019
Behavioral studies have reported interactions between number processing and spatial attention, suggesting that number processing involves shifting attention along a mental continuum on which numbers are represented in ascending order. However, direct evidence for attention shifts remains scarce, the respective contribution of the horizontal and…

De Visscher, Alice; Noël, Marie-Pascale; Pesenti, Mauro; Dormal, Valérie – Journal of Learning Disabilities, 2018
Numerous studies have tried to identify the core deficit of developmental dyscalculia (DD), mainly by assessing a possible deficit of the mental representation of numerical magnitude. Research in healthy adults has shown that numerosity, duration, and space share a partly common system of magnitude processing and representation. However, in DD,…

Van Hoof, Jo; Verschaffel, Lieven; Van Dooren, Wim – British Journal of Educational Psychology, 2017
Background: Rational numbers are of critical importance both in mathematics and in other fields of science. However, they form a stumbling block for learners. One widely known source of the difficulty learners have with rational numbers is the natural number bias, that is the tendency to (inappropriately) apply natural number properties in…

Rathé, Sanne; Torbeyns, Joke; Hannula-Sormunen, Minna M.; Verschaffel, Lieven – Mathematical Thinking and Learning: An International Journal, 2016
This study investigated the relationship between kindergartners' Spontaneous Focusing on Numerosity (SFON) and their number-related utterances during numerical picture book reading. Forty-eight 4- to 5-year-olds were individually interviewed via a SFON Imitation Task and a numerical picture book reading activity. We expected differences in the…

Degrande, Tine; Verschaffel, Lieven; Van Dooren, Wim – Mathematical Thinking and Learning: An International Journal, 2017
In contrast to previous studies on Spontaneous Focusing on Quantitative Relations (SFOR), the present study investigated not only the "extent" to which children focus on (multiplicative) quantitative relations, but also the "nature" of children's quantitative focus (i.e., the types of quantitative relations that children focus…

Vamvakoussi, Xenia; Christou, Konstantinos P.; Mertens, Lieve; Van Dooren, Wim – Learning and Instruction, 2011
It is widely documented that the density property of rational numbers is challenging for students. The framework theory approach to conceptual change places this observation in the more general frame of problems faced by learners in the transition from natural to rational numbers. As students enrich, but do not restructure, their natural number…

Van Hoof, Jo; Lijnen, Tristan; Verschaffel, Lieven; Van Dooren, Wim – Research in Mathematics Education, 2013
Rational numbers and particularly fractions are difficult for students. It is often claimed that the "natural number bias" underlies erroneous reasoning about rational numbers. This cross-sectional study investigated the natural number bias in first and fifth year secondary school students. Relying on dual process theory assumptions that…
