Impaired numerosity perception in developmental dyscalculia (low "number acuity") has been interpreted as evidence of reduced representational precision in the neurocognitive system supporting non-symbolic number sense. However, recent studies suggest that poor numerosity judgments might stem from stronger interference from non-numerical…

Rachelle M. Johnson; Sara A. Hart; Richard K. Wagner – Developmental Science, 2025
Home literacy environment (HLE) refers to children's exposure to and engagement in reading-related activities in the home. Although HLE is known to be related to successful early reading achievement in general, less is known about this relation for students with learning disabilities (LDs). We investigated the relation between HLE and reading…

Procedural learning difficulties are commonly reported in children with developmental coordination disorder (DCD), yet the neural basis of this impairment remains unclear. This study addressed this gap by examining the correlation between cortical oscillatory activity and procedural learning of a sequence of finger movements in children with and…

The MacArthur-Bates Communicative Development Inventories (CDI) are widely used, parent-report instruments of language acquisition. Here, we focus on the word-inventory sections of the instruments, and show two different approaches to modeling CDI data, based on real-world needs. First, we show that Words & Gestures data collected…

Children with dyslexia frequently also struggle with math. However, studies of reading disability (RD) rarely assess math skill, and the neurocognitive mechanisms underlying co-occurring reading and math disability (RD+MD) are not clear. The current study aimed to identify behavioral and neurocognitive factors associated with co-occurring MD among…

Samuel David Jones; Manon Wyn Jones; Kami Koldewyn; Gert Westermann – Developmental Science, 2024
This paper presents "rational inattention" as a new, transdiagnostic theory of information seeking in neurodevelopmental conditions that have uneven cognitive and socio-emotional profiles, including developmental language disorder (DLD), dyslexia, dyscalculia and autism. Rational inattention holds that the optimal solution to minimizing…
