Two questions regarding text signals' influence on second language (L2) science expository text comprehension were examined. First, the contextual relationship between verbal headings and non-verbal underlining signals (i.e., related or unrelated) was manipulated to investigate how these verbal and nonverbal text signals influence L2 text…

In this study, we examined to what extent orthographic skills, phonological processing, oral vocabulary, and word memory accounted for variance in reading comprehension among upper-elementary school children with and without dyslexia. The tasks came from the Tests of Dyslexia (TOD). Data from 753 participants (typically developing n = 575;…

Developmental dyslexia is characterized by reading and writing deficits that persist into adulthood. However, the mechanisms underlying these deficits appear to affect several language domains negatively. The present study aims to investigate how 18 native Spanish-speaking adults with developmental dyslexia perform different language tasks in…

Family literacy interventions, encompassing both meaning- and code-based activities, have generally demonstrated positive outcomes in fostering children's literacy and oral language skills. Despite the overall positive impact, the effectiveness of these interventions varies, and the distinction between the specific mechanisms underlying each…

Vocabulary teaching has traditionally focused on word meanings to aid reading comprehension, however evidence also suggests that vocabulary knowledge influences phonemic awareness and word reading. Vocabulary instruction concentrating on the sound structure of new words alongside meaning (combined sound-meaning vocabulary instruction) improves…

The current study examined the relation between the amount of literacy instruction and student reading achievement (word reading and reading comprehension), using data from 927 students and their 189 teachers from Grades 1 to 3 in the US. Literacy instruction was observed once in the Fall and once in the Spring each year from two projects. We…

This project drew upon evidence in the field of professional learning and development (PLD) in education to create and evaluate a PLD program to foster the use of narrative intervention evidence-based practices by classroom teachers working with students with language and literacy difficulties (LLD) in Grades 3 through 5. The primary aim of the…

Oral language comprehension (OLC) and vocabulary depth are widely recognized as key predictors of reading comprehension. However, research has either provided a limited representation of OLC or failed to acknowledge the distinctive predictive nature of vocabulary depth. This study investigates the combined contributions of OLC, conceptualized as a…

We investigated relations between kindergarten precursors and second-grade reading skills in deaf and hard-of-hearing (DHH) children, and aimed to identify subgroups based on reading skills, in order to explore early signs of later reading delays. DHH children (n = 23, M[subscript age] kindergarten = 6.25) participated from kindergarten-second…
