We compared the reading development of 77 deaf and hard-of-hearing (DHH) Japanese children, aged 5-7 (40 females), with 139 of their hearing peers (74 females) in 2018. We assessed each group's phonological awareness (PA), grammar, vocabulary, and reading of hiragana (Japanese orthography children learn first). DHH children showed significant…

This study examines the influence of language environment on language and reading skills and the cross-linguistic contributions to reading outcomes in 132 Spanish-English bilingual children ages 7-12 (52% female; 98% Hispanic). We present three major findings: children's language knowledge is separable into general (e.g., phonological awareness)…

Understanding how early reading and mathematics co-develop is important from both theoretical and pedagogical standpoints. Previous research has provided mixed results. This paper investigates the development of reading and mathematics in a longitudinal sample of N = 355,883 students from the United Kingdom (2005-2019) aged 5 to 12 (49% girls).…

Developmental studies examining relations between word reading (WR) and decoding in typical and dyslexic populations routinely cut the reading distribution to form distinct groups. However, dichotomizing continuous variables to study development is problematic for multiple reasons. Instead, we modeled and visualized the parallel growth of WR and…

With a focus on within-person effects, this study investigated mutualism among academic skills (reading, math, science) and between those skills and verbal working memory in a general population sample and groups with high or low skills from Grades 2 to 5 (2010-2016, N = 859-9040, age 6.27-13.13 years, 49% female, ethnically diverse). Mutualism…

This study explored whether a daytime nap aids children's acquisition of letter-sound knowledge, which is a fundamental component for learning to read. Thirty-two preschool children in Sydney, Australia (M[subscript age] = 4 years;3 months) were taught letter-sound mappings in two sessions: one followed by a nap and the other by a wakeful period.…

Preschool improves children's kindergarten readiness, but the cognitive outcomes of preschool enrollees and nonenrollees tend to converge partially or fully in elementary school. In older programs, most of this convergence occurs in kindergarten (Li et al., 2016), but evidence from today's programs is sparse. Using data on 4,971 children who…

This study investigates the cross-linguistic transfer of literacy skills in Spanish-English, Chinese-English bilingual, and English monolingual children (N = 283, 5-10 years). Research question 1 examines English literacy and asks how phonological and morpho-semantic skills contribute to word reading as a function of children's language…

This study examined the extent to which kindergarten Spanish reading affected English reading growth trajectories through fourth grade among nationally representative Spanish-speaking bilingual students (N = 312) in the United States and whether the association varied by students' English oral proficiency. Multilevel growth curve analyses revealed…

This study examined the associations between classmates' reading-related gender stereotypes and students' reading self-efficacy, self-concept, motivation, and achievement. Our sample consisted of 1,508 fifth-grade students (49% girls; age: 10.89 years); data were collected at two time points. Multilevel analyses yielded two main results: First,…

This paper used the Early Childhood Longitudinal Study-Birth Cohort (N = 1,258) to examine the influence of hilevels of cognitive stimulation from mothers, fathers, and childcare providers at 24 months and children's pre-academic skills at 48 and 60 months in two parent families. Results from path analysis showed direct positive effects of…

Most U.S. preschoolers have consumed media created with funding from the U.S. Department of Education's Ready To Learn (RTL) initiative, which was established to promote school readiness among children ages 2-8. Synthesizing data from 45 evaluations (N = 24,624 unique child participants), this meta-analysis examined the effects of RTL media…

This study investigated the influence of first language (L1) phonology on second language (L2) early reading skills in Sylheti-English bilinguals (N = 58; 48% girls; British Bangladeshi) and their monolingual-English peers (N = 43; 45% girls; 96% White British, 4% multiethnic British) in a diaspora context. Language-specific phonological awareness…

This study examined change in early language comprehension from 15 to 54 months for fifth-grade typical readers (n = 35), poor decoders (n = 11), or poor comprehenders (n = 16) from a nationally representative study of early child-care experiences. Changing measures of language comprehension were captured across early childhood for the 62…

The mechanisms underlying socioeconomic disparities in children's reading skills are not well understood. This study examined associations among socioeconomic background, home linguistic input, brain structure, and reading skills in 5-to-9-year-old children (N = 94). Naturalistic home audio recordings and high-resolution, T1-weighted MRI scans…
