Number development and developmental dyscalculia

Developmental Medicine & Child Neurology, 2007
There is a growing consensus that the neuropsychological underpinnings of developmental dyscalculia (DD) are a genetically determined disorder of ‘number sense’, a term denoting the ability to represent and manipulate numerical magnitude nonverbally on an internal number line.

Developmental Dyscalculia and Medical Assessment

Journal of Learning Disabilities, 1993
Developmental dyscalculia (DC) is a primary cognitive disorder of childhood manifested by disturbance of arithmetic ability. As an isolated learning disability (LD), it is usually treated by remedial education and not referred for further medical evaluation. We examined a group of 7 third-grade children with DC attending a mainstream school who had not

Developmental Dyscalculia and Brain Laterality

Cortex, 1995
The correlation between arithmetic dysfunction and brain laterality was studied in 25 children with developmental dyscalculia (DD). The children were tested on a standardized arithmetic battery and underwent a neurological and neuro-psychological evaluation.

Developmental Dyscalculia

Journal of Learning Disabilities, 1974
A definition of developmental dyscalculia, stressing the hereditary or congenital affection of the brain substrate of mathematical functions, is put forth. This disorder is clearly distinguished from other forms of disturbed mathematical abilities.

DEVELOPMENTAL DYSCALCULIA: PREVALENCE AND DEMOGRAPHIC FEATURES

Developmental Medicine & Child Neurology, 1996
SUMMARYOne hundred and forty‐thrée 11‐year‐old children with developmental dyscalculia, from a cohort of 3029 students, were studied to determine demographic features and prevalence of this primary cognitive disorder. They were evaluated for gender, IQ, linguistic and perceptual skills, symptoms of attention‐deficit hyperactivity disorder (ADHD), socio‐

Conceptual size in developmental dyscalculia and dyslexia.

Neuropsychology, 2018
People suffering from developmental dyscalculia (DD) are known to have impairment in numerical abilities and have been found to have weaker processing of countable magnitudes. However, not much research was done on their abilities to process noncountable magnitudes.

Inhibitory ability of children with developmental dyscalculia

Journal of Huazhong University of Science and Technology [Medical Sciences], 2011
Inhibitory ability of children with developmental dyscalculia (DD) was investigated to explore the cognitive mechanism underlying DD. According to the definition of developmental dyscalculia, 19 children with DD-only and 10 children with DD&RD (DD combined with reading disability) were selected step by step, children in two control groups were matched ...

Developmental Dyscalculia Is a Familial Learning Disability

Journal of Learning Disabilities, 2001
Whereas current evidence attests to a genetic component in the etiology of dyslexia and attention-deficit/hyperactivity disorder (ADHD), little is known about the role of genetics in developmental dyscalculia (DC). The objective of this study was to determine the familial aggregation of DC.

Procedural Dyscalculia and Number Fact Dyscalculia: Double Dissociation in Developmental Dyscalculia

Cognitive Neuropsychology, 1991
Abstract Traditional developmental models describe a series of sequenced stages and interpret developmental disorders in terms of arrested development. Two different cases of developmental dyscalculia are described which cannot both be explained against the same stage model of the development of arithmetical skill.

Developmental Dyscalculia as a Heterogeneous Disability

2014
Abstract This chapter discusses heterogeneous aspects of developmental dyscalculia (DD) in terms of behaviour, cognitive operations, and neural structures. It has been suggested that DD is an isolated learning deficiency, involves a domain-specific deficit (in the capacity to enumerate), and a specific neural deficiency (in the ...
