This article is about problems that children may have when learning mathematics, problems that are also typified in publications as 'dyscalculia'. We consider two questions. The first: Is a child a dyscalculic if it runs into trouble learning mathematics? The second: Does a child have problems when learning mathematics because it experiences…

Zimpel, André Frank; Rieckmann, Torben – International Journal of Disability, Development and Education, 2022
Empirical evidence suggests a phonological loop deficit associated with Down syndrome. A trisomy 21 may be associated with a narrowing of visual attention to fewer than four objects at a time too. In a study with computer tachistoscopy, the hypothesis was confirmed in all 194 persons with trisomy 21. The subitising limit of persons with trisomy 21…

Thompson, Talia; Stinnett, Nicole; Tartaglia, Nicole; Davis, Shanlee; Janusz, Jennifer – Journal of Research in Special Educational Needs, 2022
Students with sex chromosome aneuploidies (SCAs) are at increased risk for learning disabilities and often require individualized supports in the school setting. Parents of students with rare disorders such as SCAs possess a unique understanding of their child's educational experiences and play a crucial role in the development of successful…

Willcutt, Erik G.; McGrath, Lauren M.; Pennington, Bruce F.; Keenan, Janice M.; DeFries, John C.; Olson, Richard K.; Wadsworth, Sally J. – New Directions for Child and Adolescent Development, 2019
Current definitions of specific learning disability (SLD) identify a heterogeneous population that includes individuals with weaknesses in reading, math, or writing, and these academic difficulties often co-occur in many of the same individuals. The Colorado Learning Disabilities Research Center (CLDRC) is an interdisciplinary, multisite research…

Erbeli, Florina; Hart, Sara A.; Taylor, Jeanette – Journal of Learning Disabilities, 2019
A risk to develop a learning disability has been shown to run in families. Having a positive family history of learning disability seems to account for mean differences in achievement outcomes (reading, math) in that children with a positive family history score significantly lower compared to their peers with no such family history. However, the…

Driven by our recent mapping of the human genome, genetics research is increasingly prominent and beginning to reintersect with education research. We describe previous intersections of these fields, focusing on the ways that they were harmful. We then discuss novel features of genetics research in the current era, with an emphasis on…

Many neurodevelopmental disorders (NDDs) share common learning and behavioural impairments, as well as features such as dysregulation of the oxytocin hormone. Here, we examined DNA methylation (DNAm) in the 1st intron of the oxytocin receptor gene, "OXTR," in patients with autism spectrum (ASD), attention deficit and hyperactivity (ADHD)…

Dale, Philip S.; von Stumm, Sophie; Selzam, Saskia; Hayiou-Thomas, Marianna E. – Journal of Speech, Language, and Hearing Research, 2020
Purpose: The ability to identify children early in development who are at substantial risk for language/literacy difficulties would have great benefit both for the children and for the educational and therapeutic institutions that serve them. Information that is relatively easily available prior to the age of 3 years, such as late talking, family…

Brankaer, Carmen; Ghesquière, Pol; De Wel, Anke; Swillen, Ann; De Smedt, Bert – Developmental Science, 2017
Cross-syndrome comparisons offer an important window onto understanding heterogeneity in mathematical learning disabilities or dyscalculia. The present study therefore investigated symbolic numerical magnitude processing in two genetic syndromes that are both characterized by mathematical learning disabilities: Turner syndrome and 22q11.2 deletion…

Redley, Marcus; Pannebakker, Merel; Holland, Anthony – Journal of Applied Research in Intellectual Disabilities, 2018
Background: Advances in medical genetics herald the possibility that health and social care services could be more responsive to the needs arising from a person's genotype. This development may be particularly important for those men and women whose learning disability (known internationally as intellectual disability) is linked to a…

Margolis, Amy E.; Davis, Katie S.; Pao, Lisa S.; Lewis, Amy; Yang, Xiao; Tau, Gregory; Zhao, Guihu; Wang, Zhishun; Marsh, Rachel – Developmental Science, 2018
Verbal--spatial discrepancies are common in healthy individuals and in those with neurodevelopmental disorders associated with cognitive control deficits including: Autism Spectrum Disorder, Non-Verbal Learning Disability, Fragile X, 22q11 deletion, and Turner Syndrome. Previous data from healthy individuals suggest that the magnitude of the…

Zuckerman, Katharine E.; Lindly, Olivia J.; Sinche, Brianna – American Journal on Intellectual and Developmental Disabilities, 2016
This study aimed to assess variation in parent beliefs about causes of learning and developmental problems in U.S. children with autism spectrum disorder, using data from a nationally representative survey. Results showed that beliefs about a genetic/hereditary cause of learning/developmental problems were most common, but nearly as many parents…

Roberts, Lynette V.; Richmond, Jenny L. – Developmental Science, 2015
Individuals with Down syndrome (DS) exhibit a behavioral phenotype of specific strengths and weaknesses, in addition to a generalized cognitive delay. In particular, adults with DS exhibit specific deficits in learning and memory processes that depend on the hippocampus, and there is some suggestion of impairments on executive function tasks that…

Neuroimaging studies of Turner syndrome can advance our understanding of the X chromosome in brain development, and the modulatory influence of endocrine factors. There is increasing evidence from neuroimaging studies that TX individuals have significant differences in the anatomy, function, and metabolism of a number of brain regions; including…

Hall, Scott S.; Hustyi, Kristin M.; Hammond, Jennifer L.; Hirt, Melissa; Reiss, Allan L. – Journal of Autism and Developmental Disorders, 2014
We examined whether "discrete trial training" (DTT) could be used to identify learning impairments in mathematical reasoning in boys with fragile X syndrome (FXS). Boys with FXS, aged 10-23 years, and age and IQ-matched controls, were trained to match fractions to pie-charts and pie-charts to decimals either on a computer or with a…
