Sensory-neural studies indicate that children with developmental dyslexia show impairments in processing acoustic speech envelope information. Prior studies suggest that this arises in part from reduced sensory sensitivity to amplitude rise times (ARTs or speech "edges") in the envelope, accompanied by less accurate neural encoding of low-frequency envelope information. Accordingly, enhancing these characteristics of the speech envelope may enhance neural speech processing in children with dyslexia. Here we applied an envelope modulation enhancement (EME) algorithm to a 10-min story read in child-directed speech (CDS), enhancing ARTs and also enhancing low-frequency envelope information. We compared neural speech processing (as measured using MEG) for the EME story with the same story read in natural CDS for 9-year-old children with and without dyslexia. The EME story affected neural processing in the power domain for children with dyslexia, particularly in the delta band (0.5-4 Hz) in the superior temporal gyrus. This may suggest that prolonged experience with EME speech could ameliorate some of the impairments shown in natural speech processing by children with dyslexia.

Parents' Perception of the Role of Sports in Supporting Psychological and Social Development in Children with Specific Learning Disorders.

Background: This study aims to examine parents' perceptions of how coach support influences the satisfaction of basic psychological needs (autonomy, competence, and relatedness) and its subsequent impact on the self-esteem and overall well-being of children with Specific Learning Disorders (SLDs) through participation in sports.
Methods: The sample consisted of 1146 parents of children and young people diagnosed with SLDs from several European countries. The Coach Support Scale (COS), the Basic Psychological Needs Satisfaction Scale (BPNS), the Rosenberg Self-Esteem Scale (RSES), and the Sport Impact Scale (SIS) were used.
Hebbian Optocontrol of Cross-Modal Disruptive Reading in Increasing Acoustic Noise in an Adult with Developmental Coordination Disorder: A Case Report.

Acoustic noise is known to perturb reading for good readers, including children and adults. This external acoustic noise interfering at the multimodal areas in the brain causes difficulties reducing reading and writing performances. Moreover, it is known that people with developmental coordination disorder (DCD) and dyslexia have reading deficits even in the absence of acoustic noise.

Purpose: Interprofessional practice requires regular communication between professionals from different disciplines using shared terminology. Within schools, many professionals are tasked with supporting children with language disorders, namely, developmental language disorder (DLD) and/or dyslexia. Limited information exists as to (a) how school-based professionals' definitions of DLD and dyslexia align with research definitions, (b) how different school-based professionals define language disorders, (c) how school-based professionals' definitions of DLD and dyslexia align across professional groups, and (d) how one's definition of a language disorder correlates with other measures of knowledge.

Motor-free visual perception abilities are important reference indicator for children's literacy skills. In the absence of Chinese norms, this study utilized the motor-free visual perception test-4 (MVPT-4) to assess the visual perception abilities of children aged 5-12 years in Xuzhou, China, to lay the foundation for establishing standardized norms in China. From May to July 2023, a stratified random sampling method was used to conduct MVPT-4 evaluation on 525 kindergarten and primary school children in Xuzhou, China.

We examined how thalamocortical connectivity structure reflects children's reading performance. Diffusion-weighted MRI at 3 T and a series of reading measures were collected from 64 children (33 girls) ages 8-14 years with and without dyslexia. The topological properties of the left and right thalamus were computed based on the whole-brain white matter network and a hub-attached reading network, and were correlated with scores on several tests of children's reading and reading-related abilities.
