Developmental dyslexia (DD) is a common reading disability, affecting 5% to 11% of children in North America. Children classified as having DD often have a history of early language delay (ELD) or language impairments. Nevertheless, studies have reported conflicting results as to the association between DD-ELD and the extent of current language…

To investigate the longitudinal effects of two domain-general cognitive abilities, namely verbal working memory and visual search skill, on Chinese reading comprehension. To evaluate whether decoding and linguistic comprehension mediate such effects. A total of 202 first-grade Chinese-speaking children from mainland China (M[subscript]age =…

Measures of decoding and oral language have been shown to predict early reading comprehension across a wide variety of languages, though the timeframe and strength of the predictions vary by orthographic depth. This study is the first to examine predictors of early reading in Vietnamese, a transparent orthography of Romanized letters and…

Oral language and word reading skills have important effects on reading comprehension. The Wechsler Individual Achievement Test-Third Edition (WIAT-III) measures both skill sets, but little is known about their specific effects on reading comprehension within this battery. Path analysis was used to evaluate the collective effects of reading and…

Although publicly-funded prekindergarten (pre-k) programs have been designed to promote children's school readiness, programs have tended to support early literacy skills to a greater degree than early language skills. Given the importance of both language and literacy skills for children's reading acquisition and academic achievement, the present…

The aim of the present study was to investigate the correlational and predictive relationships between parents with low literacy skills (n = 96) and their 3-5 year old children's emergent literacy skills (n = 96). In the study parents were assessed on measures of reading comprehension, decoding, fluency, oral vocabulary, and word identification,…

We examined growth trajectories of writing and the relation of children's socioeconomic status and language and/or speech impairment to the growth trajectories. First-grade children (N = 304) were assessed on their written composition in the fall, winter, and spring, and their vocabulary and literacy skills in the fall. Children's SES had a…

Genetic and environmental relations between vocabulary and reading skills were explored longitudinally from preschool through Grades 2 and 4. At preschool there were strong shared-environment and weak genetic influences on both vocabulary and print knowledge but substantial differences in their source. Separation of etiology for vocabulary and…

Adult literacy interventions often rely on models of reading validated with children or adult populations with a broad range of reading abilities. Such models do not fully satisfy the need for intervention research and development for adults with low literacy. Thus, the authors hypothesized that a model representing the relationship between…
