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…

Schneider, Michael; Merz, Simon; Stricker, Johannes; De Smedt, Bert; Torbeyns, Joke; Verschaffel, Lieven; Luwel, Koen – Child Development, 2018
The number line estimation task is widely used to investigate mathematical learning and development. The present meta-analysis statistically synthesized the extensive evidence on the correlation between number line estimation and broader mathematical competence. Averaged over 263 effect sizes with 10,576 participants with sample mean ages from 4…

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…

Depaepe, Fien; Van Roy, Patrick; Torbeyns, Joke; Kleickmann, Thilo; Van Dooren, Wim; Verschaffel, Lieven – Educational Studies in Mathematics, 2018
The transition from natural to rational numbers is difficult for most elementary school children. A major cause for these difficulties is assumed to be the "conceptual change" they need to undergo in order to see that several natural number properties do not apply to rational numbers. To appropriately handle pupils' difficulties,…

Bojorque, Gina; Torbeyns, Joke; Hannula-Sormunen, Minna; Van Nijlen, Daniël; Verschaffel, Lieven – European Journal of Psychology of Education, 2017
This study explored the development of Ecuadorian Kindergartners' spontaneous focusing on numerosity (SFON) during the kindergarten year, as well as the contribution of early numerical abilities to this development. One hundred Kindergartners coming from ten classrooms received two SFON tasks, one at the beginning and one at the end of the school…

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…
