    Abstract : Children’s early mathematics learning and development have become a topic of increasing interest over the past decade since early mathematical knowledge and skills have been shown to be a strong predictor of later mathematics performance. Understanding how children develop mathematical knowledge and skills and how they can be supported in their early learning could thus prove to be a vital component in promoting learning of more formal mathematics.

  2. 2. “Count on me!” : Mathematical development, developmental dyscalculia and computer-based intervention

    Author : Linda Olsson; Ulf Träff; Joakim Samuelsson; Lisa Thorell; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mathematical development; symbolic number processing; Approximate number system; developmental dyscalculia; computer-based intervention; matematisk utveckling; symboliskt nummerprocessande; Approximativa nummersystemet; dyskalkyli; datorbaserad intervention;

    Abstract : A “sense” of number can be found across species, yet only humans supplement it with exact and symbolic number, such as number words and digits. However, what abilities leads to successful or unsuccessful arithmetic proficiency is still debated. READ MORE

  3. 3. Neurocognitive Foundations of Child and Adult Number Processing : Neural Correlates and Functional Circuits Across Typical Development

    Author : Mikael Skagenholt; Ulf Träff; Kenny Skagerlund; Karin Kucian; Linköpings universitet; []

    Abstract : The ability to mentally represent the exact numerosity of up to four perceived objects, as well as approximately estimating differences in numerical magnitude, appears to constitute a core-cognitive number sense. Symbolic representations of number (e.g. READ MORE

  4. 4. Magnitude Processing in Developmental Dyscalculia : A Heterogeneous Learning Disability with Different Cognitive Profiles

    Author : Kenny Skagerlund; Ulf Träff; Thomas Karlsson; Bert De Smedt; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Developmental Dyscalculia; mathematical learning disabilities; number sense; Dyskalkyli; matematiksvårigheter; antalsuppfattning;

    Abstract : Developmental dyscalculia (DD) is a learning disability that is characterized by severe difficulties with acquiring age-appropriate mathematical skills that cannot be attributed to insufficient education, language skills, or motivation. The prevalence rate is estimated at 3-6%, meaning that a substantial portion of the population struggles to learn mathematics to such a large degree that it affects overall well-being and academic prospects.

  5. 5. Mathematical Learning Disability : Cognitive Conditions, Development and Predictions

    Author : Rickard Östergren; Ulf Träff; Joakim Samuelsson; Örjan Dahlström; Åke Olofsson; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Mathematical learning disability; dyscalculia; mathematical cognition; number sense; Matematiska inlärningssvårigheter; dyskalkyli; matematisk kognition; antalsuppfattning;

    Abstract : The purpose of the present thesis was to test and contrast hypotheses about the cognitive conditions that support the development of mathematical learning disability (MLD). Following hypotheses were tested in the thesis: a) domain general deficit, the deficit is primarily located in the domain general systems such as the working memory, b) number sense deficit, the deficit is located in the innate approximate number system (ANS), c) numerosity coding deficit, the deficit is located to a exact number representation system, d) access deficit, the deficit is in the mapping between symbols and the innate number representational system (e.
