It is widely recognized that individuals with dyslexia have difficulties with word reading and spelling, and individuals with reading comprehension difficulties have low vocabulary knowledge. However, little is known about the extent to which spelling and vocabulary are informative of reading difficulties. In the present study, we investigated…

Background: Spelling is a prevalent strategy to teach children to read. However, research on the mechanism underlying the contribution of spelling to reading comprehension in Chinese children is limited. Methods: The primary aim of this study was to investigate the concurrent and longitudinal associations between spelling and reading comprehension…

Definitions of dyslexia typically make reference to unexpected poor reading, although how best to operationalize unexpected remains an issue. When operationally defined as reading below expectations based on the level of oral language, cases of unexpected poor reading make up fewer than half of cases of poor reading, and cases of unexpected poor…

Substantial research among bilingual adults indicates that exposure to words primes other semantically related words within and across languages, as well as the direct translation equivalents [e.g. Chen and Ng 1989. "Semantic Facilitation and Translation Priming Effects in Chinese-English Bilinguals." "Memory & Cognition"…

Purpose: This study examines the extent to which the Home Literacy Environment (HLE) as measured by reading habits and resources, library use, and subscriptions or materials, as well as parental reading beliefs predict both language skills (i.e., vocabulary) at kindergarten and students' trajectories of growth from kindergarten (K) to grade 3…

The purpose of this study was threefold: to examine unique and shared risk factors of comorbidity for reading comprehension and word-problem solving difficulties, to explore whether language minority (LM) learners are at increased risk of what we refer to as "higher order comorbidity" (reading comprehension and word-problem solving…

Many primary grade students are not afforded nonfiction-rich opportunities, with fiction comprising the majority of books read aloud in classrooms. With the Common Core Standards recommending that half of the texts made available to students be nonfiction, educators are increasing their use of informational text. The present study explored the…

The aim of this study was to investigate the early characteristics of four profiles of readers established in second grade (7-8 years of age): good readers, specific poor decoders, specific poor comprehenders and general poor readers. These profiles were compared retrospectively on a range of measures administered 2 years earlier, in kindergarten.…

The present study investigated language skills and reading comprehension with English monolingual and Spanish-English bilingual children in grades 2-5. Of the 377 children in the sample, 207 were English monolingual and 170 were Spanish-English bilingual. Data were collected within a cohort-sequential design for two academic years in the fall and…

Lervag and Hulme’s neuro-developmental theory and Wolf and Bowers’s double-deficit hypothesis were examined in this longitudinal study. A total of 130 children were tested in preschool and followed through fifth grade, when 84 remained in the study. During preschool and kindergarten the participants were given tests of end-sound discrimination…

Children learning English as an additional language (EAL) often experience difficulties with reading comprehension relative to their monolingual peers. While low levels of vocabulary appear to be one factor underlying these difficulties, other factors such as a relative lack of appropriate background knowledge may also contribute. Sixteen children…

We report a longitudinal study investigating the predictors of reading comprehension and word reading accuracy between the ages of 7 to 8 (UK Year 3) and 10 to 11 years (Year 6). We found that different skills predicted the development of each. Reading comprehension skill measured in Year 3 was a strong predictor of comprehension in Year 6;…

The presence of Matthew effects was tested in students of varying reading, spelling, and vocabulary skills. A cross-sequential design was implemented, following 587 Grade 2 through 4 students across five measurement points (waves) over 2 years. Students were administered standardized assessments of reading, spelling, and vocabulary. Results…

In this study, we examined the relationship of growth trajectories of oral reading fluency, vocabulary, phonological awareness, letter-naming fluency, and nonsense word reading fluency from 1st grade to 3rd grade with reading comprehension in 1st, 2nd, and 3rd grades. Data from 12,536 children who were followed from kindergarten to 3rd grade…

Technical adequacy and information/cost return were examined for four early reading measures: the Dynamic Indicators of Basic Early Literacy Skills (DIBELS), STAR Early Literacy (SEL), Group Reading Assessment and Diagnostic Evaluation (GRADE), and the Texas Primary Reading Inventory (TPRI). All four assessments were administered to the same…
