Background: Prominent theories of reading make the prediction that individual differences in children's word learning capacity determine the pace of their acquisition of reading skill. Despite the developmental nature of some of these theories, most empirical research to date has explored the relation between word learning capacity and reading at…

Background: Word-to-text integration (WTI) can be challenging for second-language (L2) learners, although it can positively contribute to reading comprehension. The present study examined the role of WTI, after controlling for decoding, vocabulary and morphosyntactic awareness, in predicting English as an L2 reading comprehension development in…

Background: Vocabulary knowledge (VK) and morphological awareness (MA) are crucial linguistic variables for reading comprehension. However, the extent to which MA subskills are intertwined with different facets of VK in their contributions to reading comprehensions, and how MA influences the reading abilities of English as a foreign language (EFL)…

Background: Cognitive and linguistic factors have been incorporated into models to explain reading comprehension beyond classical models of reading. This study explores the contribution of executive functions, mainly domain-general and reading-specific cognitive flexibility, in reading comprehension of science texts in monolingual Spanish speaking…

Background: Teaching vocabulary may be an effective way to address poor reading comprehension. However, it is unclear how many words or word families a school aged child with poor vocabulary would need to learn to meaningfully impact comprehension. This study provides estimates of vocabulary size for children with differing vocabulary achievement…

Educators and researchers agree that oral language is fundamental to students' reading acquisition. It is not clear how best to conceptualise oral language within models of reading -- as one's overall understanding of spoken language, or as individual skills, each with unique contributions to children's reading comprehension. In our longitudinal…

The aim of this study was to examine variation in early reading comprehension development for second language (L2) readers compared with first language (L1) readers and to investigate the impact of vocabulary knowledge in their first and second language. Participants were 75 Dutch monolingual children (L1 readers) and 71 Turkish-Dutch bilingual…

Background: Morphological analysis skill is the ability to problem-solve meanings of unfamiliar words by applying knowledge of morphological constituents. For vocabulary words from the academic layer of English, the major, meaning-carrying morphological constituents are Latin roots (nov meaning 'new' in innovative). The degree to which…

Background: In countries with German as an official language, children with German as a second language perform overall worse in school than their German native speaking peers. This particularly affects written language skills, which require advanced language knowledge. The reasons are manifold, but one is prominent, namely poor vocabulary…

This study investigated the relationships among vocabulary breadth, vocabulary depth, reading comprehension, and reading rate among college-aged students. While the relationships of some of these variables have been explored in previous research, the current study's focus on the role of vocabulary depth on the literacy measures within a sample of…

Background: Reading comprehension is a complex process influenced by many factors. However, the abilities that are known to influence reading comprehension may not contribute equally for children with different levels of oral language. Aims: Here we examined the relationship of two factors known to influence reading comprehension (morphology and…

Aims: The primary aim of this study is to augment our understanding of the component skills that underpin second-language learners' text comprehension by examining the direct and indirect roles of vocabulary knowledge and grammatical skills in second-language learners' listening and reading comprehension. Methods: Our sample included 134 learners…

The present study examined children's digital text comprehension of digital text types linear digital text vs hypertext, with or without graphical navigable overviews. We investigated to what extent individual variation in children's comprehension could be explained by lexical quality (word reading efficiency and vocabulary knowledge), cognitive…

This study examined the dimensionality of morphological knowledge. The performance of 371 seventh- and eighth-graders on seven morphological knowledge tasks was investigated using confirmatory factor analysis. Results suggested that morphological knowledge was best fit by a bifactor model with a general factor of morphological knowledge and seven…

Children learning English as an additional language (EAL) are a growing population of learners in English primary schools. These children begin school with differing levels of English language proficiency and tend to underperform in relation to their non-EAL peers on measures of English oral language and reading. However, little work has examined…
