Temporal abnormalities in children with developmental dyscalculia.

2012

Recent imaging studies have associated Developmental dyscalculia (DD) to structural and functional alterations corresponding Parietal and the Prefrontal cortex (PFC). Since these areas were shown also to be involved in timing abilities, we hypothesized that time processing is abnormal in DD. We compared time processing abilities between 10 children with pure DD (8 years old) and 11 age-matched healthy children. Results show that the DD group underestimated duration of a sub-second scale when asked to perform a time comparison task. The timing abnormality observed in our DD participants is consistent with evidence of a shared fronto-parietal neural network for representing time and quantity.…

Contributions of longitudinal studies to evolving definitions and knowledge of developmental dyscalculia

2013

Abstract In the last 20 years, longitudinal studies have demonstrated that it is important to attend to the stability of mathematical performance over time as a facet of dyscalculia, that the manifestation of mathematics difficulties changes with development, and that individual differences in cognitive profiles and learning trajectories observed in children with mathematics difficulties implicate differences between dyscalculic and non-dyscalculic subgroups. Intra-individual differences over time, and external factors related to children's learning environments, also contribute to performance trajectories; moreover, these factors may explain the inconsistent performance profiles observed a…

Early Signs of Mathematics Anxiety?

2012

Abstract Mathematics anxiety refers to individual's negative affect when engaging in numerical and mathematical tasks. Researchers have recently connected high math anxiety to lower performance on math tasks, developmental dyscalculia, and lower self-efficacy towards math learning. Math anxiety scales have been made and validated mainly for secondary school and high school students. In our paper we are looking for early signs of math anxiety using a Pictorial Test (37 pictures) which we have developed for 6 to 8 year old children. Children were asked to concentrate on one picture at a time and to write down spontaneously their emotional and mathematical ideas. Most powerful sources of sadne…

Training of Attention in Children With Low Arithmetical Achievement

2014

This study focuses on the role of attentional processes in arithmetical skills and examines if training of basic attentive skills may improve also working memory abilities reducing arithmetic difficulties. In order to study the efficacy of attentional treatment in arithmetic achievement and in enhancing working memory abilities a test-treatment-retest quasi experimental design was adopted. The research involved 14 children, attending fourth and fifth grades, with Arithmetical Learning Disabilities (ALD) assigned to experimental and control conditions. The numerical comprehension and calculation processes were assessed using the ABCA battery (Lucangeli, Tressoldi, & Fiore, 1998). Attenti…

Anxiety, self-esteem and self-handicapping: A comparison between pupils with dyscalculia and normal learning | Ansia, autostima e self-handicapping: …

2014

Clinical and educational research places emphasis on the emotional and motivational factors which characterise learning disabilities. The aim of this research is to study the relationship between the school anxiety, the school self-esteem and the employ of self-handicapping strategies in children with dyscalculia and normal learning. Sixty pupils attending third grade junior school were given a battery of tests assessing emotional and motivational variables. On the whole, the results show that children with dyscalculia have higher levels of anxiety and lower self-esteem. Moreover, the anxiety seems to influence the self-esteem only in the group of children with normal learning.

Exploring working memory in children with low arithmetical achievement

2005

Abstract This research aimed at exploring the working memory functions in children with low arithmetical achievement and normal reading, compared to age matched controls (mean age 9 years). All the children completed a series of working memory tasks, involving the central executive functions (using both linguistic and numerical material), the phonological loop (using words, pseudo-words and digits) and the visual sketchpad (using both static visual-spatial patterns and visual-spatial sequences). Results indicated that poor arithmeticians performed worse than age-matched controls in all the visual sketchpad tasks and in all the central executive tasks, whether they used linguistic or numeric…

Tactile enumeration: A case study of acalculia

2018

Abstract Enumeration is one of the building blocks of arithmetic and fingers are used as a counting tool in early steps. Subitizing—fast and accurate enumeration of small quantities—has been vastly studied in the visual modality, but less in the tactile modality. We explored tactile enumeration using fingers, and gray matter (GM) changes using voxel-based morphometry (VBM), in acalculia. We examined JD, a 22-year-old female with acalculia following a stroke to the left inferior parietal cortex. JD and a neurologically healthy normal comparison (NC) group reported how many fingers were stimulated. JD was tested at several time points, including at acute and chronic phases. Using the sensory …
