Article Abstract

Early reading skills are critical for later academic outcomes, which include mathematics. Yet, these relations may vary by a child's ability level. This study examined how early reading skills relate to different levels of third-grade mathematics. The samples included 105 same-sex twin pairs (210 individuals, 57% female, 43% male) from the ongoing longitudinal Western Reserve Reading and Math Projects, assessed at kindergarten ( = 6.18, = 0.44) and third grade ( = 9.07, = 0.49). Kindergarten reading measures consisted of the Letter Identification task from the Woodcock Reading Mastery Test-Revised Normative Update, the Deletion subtests from Phonological Awareness Test, and the Letter Naming Fluency task from the Dynamic Indicators of Basic Early Literacy Skills; third-grade math measures included Calculation, Fluency, Applied Problem, and Quantitative Concepts subtests of Woodcock-Johnson III Tests of Achievement. Both linear and quantile regressions were conducted using reading measures as predictors and math measures as the dependent variables. Linear regressions indicated that the Deletion Summary Score was a unique predictor of Applied Problems, and Letter Naming Fluency was a significant and unique predictor of Calculation Fluency and Quantitative Concepts. Quantile regressions provided a more thorough analysis of these relations. It was found that Letter Naming Fluency was significantly associated with Calculation, Calculation Fluency, and Quantitative Concepts at the lower level. The Deletion Summary Score had relatively stable relations with Applied Problems across all levels. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Background: Children in low- and middle-income countries face obstacles to optimal language and cognitive development due to a variety of factors related to adverse socioeconomic conditions. One of these factors is compromised caregiver-child interactions and associated pressures on parenting. Early development interventions, such as dialogic book-sharing (DBS), address this variable, with evidence from both high-income countries and urban areas of low- and middle-income countries showing that such interventions enhance caregiver-child interaction and the associated benefits for child cognitive and socioemotional development.

Distinct neural processing underlying visual face and object perception in dyslexia.

Neuropsychologia

Developmental dyslexia is a disorder marked by difficulties in reading, spelling, and connecting sounds to written language. The high-level visual dysfunction hypothesis suggests these difficulties may partially arise from abnormalities in high-level visual cognition such as the ability to integrate visual input for higher-order cognitive functions such as reading. Here we examined adult (mean age = 35) dyslexic readers' neural functioning as they recognized identities of nonlinguistic visual objects, specifically houses and faces.

Percutaneous pelvic screwing (PPS) enables fixation of traumatic or atraumatic fractures with little or no displacement, or displaced but reduced fractures, and preventive fixation of primary or secondary tumoral lesions. It is a relatively recent technique, and indications are evolving with progress in pre- and intra-operative imaging. Morbidity is lower than with open surgery.

Introduction: The Certifications of Visual Impairment (VI) system was implemented to quantify and classify the incidence of visual impairment amongst the England and Wales population. This retrospective study investigates the trend in the certification of VI amongst children aged <16 years old.

Methods: CVI data provided by the Certifications Office, was extracted and assessed to identify the various causes of mild-moderate (SI) and severe (SSI) visual impairment between 2009-2022.

Background Over 300 mutations in have been identified as causes of early-onset Alzheimer's disease (EOAD). While these include missense mutations and a few insertions, deletions, or duplications, none result in open reading frame shifts, and all alter γ-secretase function to increase the long/short Aβ ratio. Methods We identified a novel heterozygous nonsense variant, c.
