Changes in the superior longitudinal fasciculus and anterior thalamic radiation in the left brain are associated with developmental dyscalculia [PDF]
Frontiers in Human Neuroscience, 2023 Developmental dyscalculia is a neurodevelopmental disorder specific to arithmetic learning even with normal intelligence and age-appropriate education. Difficulties often persist from childhood through adulthood lowering the individual’s quality of life.

Delayed development of basic numerical skills in children with developmental dyscalculia [PDF]
Frontiers in Psychology, 2023 Research suggests that children with developmental dyscalculia (DD) have deficits in basic numerical skills. However, there is conflicting evidence on whether basic numerical skills in children with DD are qualitatively different from those in typically ...

Enumeration and Alertness in Developmental Dyscalculia [PDF]
Journal of Cognition, 2019 Enumeration, the ability to report an amount of elements, differs as a function of range. Subitizing (quantities 1–4) is an accurate and quick process with reaction times (RTs) minimally affected by the number of presented elements within its range.

Impaired large numerosity estimation and intact subitizing in developmental dyscalculia. [PDF]
PLoS ONE, 2020 It is believed that the approximate estimation of large sets and the exact quantification of small sets (subitizing) are supported by two different systems, the Approximate Number System (ANS) and Object Tracking System (OTS), respectively.
