Träff, Ulf; Skagerlund, Kenny; Östergren, Rickard; Skagenholt, Mikael – British Journal of Educational Psychology, 2023
Background: Children's numerical and arithmetic skills differ greatly already at an early age. Although research focusing on accounting for these large individual differences clearly demonstrates that mathematical performance draws upon several cognitive abilities, our knowledge concerning key abilities underlying mathematical skill development is…

Träff, Ulf; Olsson, Linda; Skagerlund, Kenny; Östergren, Rickard – Journal of Educational Psychology, 2020
This study examined cognitive precursors of hierarchical mathematical development. Six-year-old children (n = 258) were assessed on number skills, cognitive skills, and arithmetic 1 year prior to school entry. Skills in advanced arithmetic and advanced mathematics were assessed in Grades 3 and 6, respectively. Path analyses were computed and…

Korhonen, Johan; Nyroos, Mikaela; Jonsson, Bert; Eklöf, Hanna – Educational Psychology, 2018
The aim of this study was to investigate the interplay between test anxiety and working memory (WM) on mathematics performance in younger children. A sample of 624 grade 3 students completed a test battery consisting of a test anxiety scale, WM tasks and the Swedish national examination in mathematics for grade 3. The main effects of test anxiety…

Hassler Hallstedt, Martin; Klingberg, Torkel; Ghaderi, Ata – Journal of Educational Psychology, 2018
Using a randomized placebo controlled design, we examined the direct and follow-up effects (at 6 and 12 months) of a mathematics tablet intervention. Math training focused primarily on basic arithmetic (addition and subtraction facts up to 12), and secondarily on number knowledge and word problems. We investigated the moderating effects of IQ and…

Skagerlund, Kenny; Träff, Ulf – Journal of Learning Disabilities, 2016
This study investigated if developmental dyscalculia (DD) in children with different profiles of mathematical deficits has the same or different cognitive origins. The defective approximate number system hypothesis and the access deficit hypothesis were tested using two different groups of children with DD (11-13 years old): a group with…

Gustafson, Stefan; Falth, Linda; Svensson, Idor; Tjus, Tomas; Heimann, Mikael – Journal of Learning Disabilities, 2011
In a longitudinal intervention study, the effects of three intervention strategies on the reading skills of children with reading disabilities in Grade 2 were analyzed. The interventions consisted of computerized training programs: One bottom-up intervention aimed at improving word decoding skills and phonological abilities, the second…
