Lexical quality and executive control predict children’s first and second language reading comprehension

This study compared how lexical quality (vocabulary and decoding) and executive control (working memory and inhibition) predict reading comprehension directly as well as indirectly, via syntactic integration, in monolingual and bilingual fourth grade children. The participants were 76 monolingual and 102 bilingual children (mean age 10 years, SD = 5 months) learning to read Dutch in the Netherlands. Bilingual children showed lower Dutch vocabulary, syntactic integration and reading comprehension skills, but better decoding skills than their monolingual peers. There were no differences in working memory or inhibition. Multigroup path analysis showed relatively invariant connections between predictors and reading comprehension for monolingual and bilingual readers. For both groups, there was a direct effect of lexical quality on reading comprehension. In addition, lexical quality and executive control indirectly influenced reading comprehension via syntactic integration. The groups differed in that inhibition more strongly predicted syntactic integration for bilingual than for monolingual children. For a subgroup of bilingual children, for whom home language vocabulary data were available (n = 56), there was an additional positive effect of home language vocabulary on second language reading comprehension. Together, the results suggest that similar processes underlie reading comprehension in first and second language readers, but that syntactic integration requires more executive control in second language reading. Moreover, bilingual readers additionally benefit from first language vocabulary to arrive at second language reading comprehension.     

Development of comprehension monitoring in beginner readers

The current study was designed to understand the development of comprehension monitoring among beginner readers from first to third grade, and to determine the extent to which first graders’ comprehension monitoring predicts reading comprehension in grade three. Participants were 113 children (57% female) from four US states who were followed from Grade 1 (M = 7 years, SD = 4 months) to Grade 3 (M = 9 years, SD = 4 months). Measures included decoding, vocabulary, working memory, comprehension monitoring, and reading comprehension. Children’s ability to monitor comprehension grew significantly from first to third grade, with a deceleration in growth over time. In addition, comprehension monitoring in Grade 1 made a significant contribution to reading comprehension in Grade 3, even after controlling for decoding, vocabulary, and working memory. Together, these findings supplement our understanding of young readers’ development of comprehension monitoring as well as its association with reading comprehension at a later time. Practical implications of the results in the context of providing support for higher-level language skills in beginning reading instruction are discussed.     

Is the Whole Greater Than the Sum of Its Parts? Modeling the Contributions of Language Comprehension Skills to Reading Comprehension in the Upper Elementary Grades

Language comprehension is crucial to reading. However, theoretical models and recent research raise questions about what constitutes this multifaceted domain. We present two related studies examining the dimensionality of language comprehension and relations to reading comprehension in the upper elementary grades. Studies 1 (Grade 6; N = 148) and 2 (Grade 3–5; N = 311) contrasted factor models of language comprehension using item level indicators of morphological awareness and vocabulary (Studies 1 and 2) and syntactic awareness (Study 2). In both studies, a bifactor model—including general language comprehension and specific factors for each language component—best fit the data, and general language comprehension was the strongest predictor of reading comprehension. In Study 2, the morphology-specific factor also uniquely predicted reading comprehension above and beyond general language comprehension. Results suggest the value of modeling the common proficiency underlying performance on tasks designed to tap theoretically distinct language comprehension skills.     

Language and Cognitive Predictors of Text Comprehension: Evidence From Multivariate Analysis

Using data from children in South Korea (N = 145, M_age = 6.08), it was determined how low‐level language and cognitive skills (vocabulary, syntactic knowledge, and working memory) and high‐level cognitive skills (comprehension monitoring and theory of mind [ToM]) are related to listening comprehension and whether listening comprehension and word reading mediate the relations of language and cognitive skills to reading comprehension. Low‐level skills predicted comprehension monitoring and ToM, which in turn predicted listening comprehension. Vocabulary and syntactic knowledge were also directly related to listening comprehension, whereas working memory was indirectly related via comprehension monitoring and ToM. Listening comprehension and word reading completely mediated the relations of language and cognitive skills to reading comprehension.     

Why the Simple View of Reading Is Not Simplistic: Unpacking Component Skills of Reading Using a Direct and Indirect Effect Model of Reading (DIER)

Pathways of relations of language, cognitive, and literacy skills (i.e., working memory, vocabulary, grammatical knowledge, inference, comprehension monitoring, word reading, and listening comprehension) to reading comprehension were examined by comparing four variations of direct and indirect effects model of reading. Results from 350 English-speaking second graders revealed that language and cognitive component skills had direct and indirect relations to listening comprehension, explaining 86% of variance. Word reading and listening comprehension completely mediated the relations of language and cognitive component skills to reading comprehension and explained virtually all the variance in reading comprehension. Total effects of component skills varied from small to substantial. The findings support the direct and indirect effects model of reading model and indicate that word reading and listening comprehension are upper-level skills that are built on multiple language and cognitive component skills, which have direct and indirect relations among themselves. The results underscore the importance of understanding nature of relations.     

The Relation Between Morphological Awareness and Reading Comprehension: Evidence From Mediation and Longitudinal Models

We examined the role of a hypothesized factor in reading comprehension: morphological awareness, or the awareness of and ability to manipulate the smallest meaningful units or morphemes. In this longitudinal study, we measured English-speaking children’s morphological awareness, word reading skills, and reading comprehension at Grades 3 and 4, in addition to their phonological awareness, vocabulary, and nonverbal ability as control measures. Path analyses revealed that word reading skills partially mediated the relationship between morphological awareness and reading comprehension at each grade. Further, children’s early morphological awareness partially explained children’s gains in reading comprehension, and their early reading comprehension partially explained their gains in morphological awareness. These findings support the predictions of recent models of reading comprehension: that morphological awareness impacts reading comprehension both indirectly through word reading skills and directly through the language system and that morphological awareness underpins the development of reading comprehension (e.g., Perfetti, Landi, & Oakhill, 2005).     

A not-so-simple view of reading: how oral vocabulary and visual-word recognition complicate the story

The present study sought to clarify the relations amongst serial decoding, irregular word recognition, listening comprehension, facets of oral vocabulary and reading comprehension in two cohorts of children differing in reading level. In the process, the components of the simple view of reading were evaluated. Students in grades 1 (n = 67) and 6 (n = 56) were assessed on measures of phonological awareness, decoding, irregular word recognition, listening comprehension, oral vocabulary, and reading comprehension. Even when all other measures were controlled, vocabulary was found to explain reading comprehension in grade 6 but not grade 1. Vocabulary also predicted decoding in grade 6 and irregular word recognition in both grades. These results are interpreted as supporting a not-so-simple view of the constructs underlying reading comprehension that acknowledges complex connections between print skills and oral language.     

Improving the Odds: Identifying Language Activities that Support the Language Development of Preschoolers with Poorer Vocabulary Skills

The aim of the current study is to determine what language activities Norwegian preschool children took part in, and to examine whether these language activities predict children’s language comprehension. We tested children (n?=?134) with language measures at age 4/5 and age 5/6 and interviewed their teachers (n?=?71) about the kinds of language activities the children engaged in during that school year. Teachers reported a variety of classroom language activities, ranging from informal language stimulation of everyday situations to more explicit language activities such as book reading, language games, vocabulary training and school preparation groups. Book reading every day significantly predicted children’s language comprehension.     

Language and reading development in children learning English as an additional language in primary school in England

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 the developmental trajectories of these skills in EAL learners in England. EAL learners and 33 non-EAL peers in Year 4 (age 8–9 years) were assessed at three time points over 18 months on measures of oral language (vocabulary, grammar and listening comprehension), phonological processing (spoonerisms and rapid automatised naming) and reading skills (single-word decoding and passage reading). At t1, EAL learners scored significantly lower than non-EAL peers in receptive and expressive vocabulary (breadth but not depth), spoonerisms and passage reading accuracy. Contrary to previous research, no significant group differences were found in listening or reading comprehension skills. With the exception of passage reading accuracy, there was no evidence for convergence or divergence between the groups in rate of progress over time. After three years of English-medium classroom instruction, EAL learners continue to underperform relative to their non-EAL peers in breadth of English vocabulary knowledge. This discrepancy in vocabulary knowledge does not appear to narrow as a result of regular classroom instruction in the run up to the final stages of primary school, pinpointing vocabulary as a key target for intervention.     

Differential growth patterns in emerging reading skills of Turkish-German bilingual and German monolingual primary school students

Students from Turkish-speaking families are the largest minority language group in Germany. Yet, little is known about this group’s literacy development. Using data from a 3-year longitudinal study, we examined whether the same base reading skills are involved in early reading comprehension of 100 Turkish-German bilingual and 69 German monolingual children. We applied a basic theoretical model of reading development to examine how emerging literacy develops for monolingual compared to bilingual children. Both the bilingual and monolingual children in this sample developed the investigated base reading skills at the same rate. However, the relations among phonological awareness, German vocabulary, and word decoding showed differential patterns in the development of German reading comprehension skills for the two groups: monolingual children appeared to make use of their phonological awareness skills more, whereas reading comprehension depended more on vocabulary skills for bilingual readers. Our findings indicate that bilingual emerging readers require specialized models of reading development to account for their unique routes into reading comprehension. The results of the study point to a need for increased attention to vocabulary building in the early phases of literacy acquisition for bilingual children.     

The Importance of Early Vocabulary for Literacy Achievement in High-Poverty Schools

Although research documents a key contribution of print skills to early literacy, vocabulary and other language skills also provide an important foundation. Focusing on a sample of several hundred low-income children in 16 urban schools that were implementing literacy interventions, 1st-grade predictors of literacy development were traced over time. Beginning-of-1st-grade letter–word identification and word attack skills were the strongest predictors of reading comprehension at the end of 1st grade. However, vocabulary was the best predictor of reading comprehension at the end of 2nd and 3rd grades. The predictive power of early print-related and phonemic-awareness skills diminished over time, yet vocabulary scores remained an important predictor. Results support an early emphasis on developing meaning skills to prepare low-income children for success in literacy.     

Effects of a Brief Tiered Language Intervention for Prekindergartners at Risk

Research Findings: Multitiered instructional frameworks are becoming a recommended approach for enhancing prevention and intervention efforts targeting early literacy and language skills. However, few studies to date have studied the feasibility of tiered oral language interventions before kindergarten; therefore, this pilot study explored the effectiveness of such an approach in prekindergarten. Teachers in 39 classrooms were randomly assigned to an experimental or comparison condition that contrasted the implementation of an intervention that had both Tier 1 (whole group) and Tier 2 (small group for at-risk children) components. The pilot study included only 4 weeks of teacher-administered intervention. Despite this short duration, a significant and large effect size (d = .81) was observed for the experimental group on a receptive target vocabulary assessment. No significant changes were found on measures of vocabulary fluency, expressive target vocabulary, or listening comprehension. It is important to note that teachers’ fidelity in implementing the intervention as designed was a significant predictor of children's learning. Practice or Policy: These findings suggest the potential promise of the multitiered instructional framework, especially when teachers can be supported in ways that ensure adequate fidelity of implementation. Implications for use in prekindergarten response-to-intervention models are discussed.     

Reading Intervention for Poor Readers at the Transition to Secondary School

This study evaluated two 20-week reading interventions for pupils entering secondary school with reading difficulties. The interventions were delivered by trained teaching assistants (three 35-min sessions per week). 287 pupils (ages 11–13) from 27 schools were randomly allocated to three groups: reading intervention (targeting word recognition and decoding skills), reading intervention plus comprehension, or a waiting list control group. Neither intervention produced statistically significant gains in word reading but the reading intervention plus comprehension intervention produced significant gains in reading comprehension (d = 0.29) and vocabulary (d = 0.34). Further evaluations of methods to improve word reading in this population are needed.     

Are Prompts Provided by Electronic Books as Effective for Teaching Preschoolers a Biological Concept as Those Provided by Adults?

Research Findings: Prior research indicates that shared book reading is an effective method for teaching biological concepts to young children. Adult questioning during reading enhances children’s comprehension. We investigated whether adult prompting during the reading of an electronic book enhanced children’s understanding of a biological concept. Ninety-one 4-year-olds read about camouflage in 3 conditions. We varied how prompts were provided: (a) read by the book, (b) read by a researcher, or (c) given face to face by the researcher. There was an interaction between children’s initial vocabulary level and condition. Children with low vocabulary scores gave fewer camouflage responses than their high-vocabulary peers, and this effect was particularly pronounced in the book-read condition. Children’s executive function was also measured and discussed. Practice or Policy: Our findings indicate that under some circumstances electronic prompts built into touchscreen books can be as effective at supporting conceptual development as the same prompts provided by a coreading adult. However, children with low vocabulary skills may be particularly supported by adult-led prompting. We suggest that adult prompting be used to motivate children to test and revise their own biological theories. Once children have learned strategies for updating their concepts, electronic prompting may be useful for scaffolding children’s transition to using the strategies when reading alone.     

Growth in reading-related skills of language minority learners and their classmates: more evidence for early identification and intervention

This longitudinal study investigated growth in reading-related skills between Grade 1 and 4 for language minority (LM) learners and their native English-speaking classmates from similarly low socioeconomic backgrounds (N = 166). Growth trajectories were compared by language background and by Grade 4 reading difficulties, with the goal of informing decisions about how early LM learners can undergo screening for risk of reading difficulties. As a group, LM learners demonstrated weaknesses in vocabulary and oral comprehension and strengths in phonological awareness that were apparent in Grade 1 and consistent through Grade 4. LM learners also demonstrated early strengths in letter-word identification but fell far below national norms by Grade 4. The subset of LM learners with word reading difficulties demonstrated major weaknesses in vocabulary, oral comprehension, phonological awareness, and working memory, whereas LM learners with specific reading comprehension difficulties demonstrated major weaknesses in vocabulary and oral comprehension; these weaknesses were apparent in Grade 1 and consistent through Grade 4, suggesting the importance of early assessment and intervention.     

The Relations Between Children’s Reading Comprehension, Working Memory, Language Skills and Components of Reading Decoding in a Normal Sample

The primary aim of the current study was to identify the strongest independent predictors of reading comprehension using word reading, language and memory variables in a normal sample of 180 children in grades 3–5, with a range of word reading skills. It was hypothesized that orthographic processing, receptive vocabulary and verbal working memory would all make independent contributions to reading comprehension. The contributions of reading speed, receptive grammatical skills, exposure to print, visuospatial working memory and verbal learning and retrieval (a measure of longer-term retention) were also investigated. Working memory tasks that required the processing and storage of numerical and spatial material were used. One of the numerical working memory tasks was based on the number span task developed by Yuill, Oakhill, and Parkin British Journal of Psychology, 1989, 80, 351–361. A visuospatial equivalent of that task was developed from the forward Corsi block task [Corsi, Abstracts International, 1973, 34, 891]. The results revealed that, after controlling for age and general intellectual ability, the word reading and the language variables had a much stronger relation with reading comprehension than the memory variables. The strongest independent predictor of reading comprehension was orthographic processing since it captured variance in both word reading, language skills and verbal working memory. The forward Corsi task and performance on a measure of verbal learning and retrieval each made small independent contributions to reading comprehension but the contribution of verbal working memory was not significant. It was concluded that tasks measuring the interplay between short-term and long-term memory, in which new information is combined with information already stored in long-term memory, may better predict reading comprehension measured with the text available than working memory tasks which only have a short-term memory component.     

Prekindergarten Interactive Book Reading Quality and Children’s Language and Literacy Development: Classroom Organization as a Moderator

Research Findings: This study examined the association between interactive book reading quality and prekindergarten children’s gains in language and literacy skills over the course of an academic year for 96 teachers and 417 children across multiple locations in the United States. Two moderators were examined, namely, children’s initial skill level and teachers’ classroom organization during an interactive read-aloud session. In keeping with prior research, interactive book reading quality, measured by examination of teachers’ extratextual talk, was positively and significantly related to children’s development of both language and literacy skills. Interactive book reading quality was not significantly moderated by children’s initial skills, with the exception that interactive book reading quality appeared most beneficial to children’s print knowledge for children entering prekindergarten with relatively low skill. The unique contribution of this study is that the association between interactive book reading quality and children’s expressive vocabulary was dependent on an organized classroom during the book reading session. Practice or Policy: The quality of teachers’ talk during interactive book reading may matter for children’s vocabulary development only when reading sessions are characterized by relatively high classroom organization. Classroom organization should be an important consideration while planning for interactive book reading sessions.     

Contributions of print exposure to first and second grade oral language and reading in Chile

This study examines the contribution of print exposure to oral language (expressive vocabulary and listening comprehension) and reading (word reading and reading comprehension) in first and second grade in Chile, and tests whether the contribution of print exposure to reading comprehension is mediated by language and word reading skills. Two‐hundred and eighty one children (mean age 6.55 years) participated. Print exposure was measured with a book‐cover recognition task in first grade, and outcomes were measured both in first and second grade. Print exposure had direct effects on all outcomes in first grade and indirect effects in second grade. Effects on first grade reading comprehension were partially mediated by listening comprehension and word reading, but not vocabulary. We discuss the importance of the findings for improving reading comprehension in countries with low access to books.     

Differential lexical predictors of reading comprehension in fourth graders

The mental lexicon plays a central role in reading comprehension (Perfetti & Stafura, 2014). It encompasses the number of lexical entries in spoken and written language (vocabulary breadth), the semantic quality of these entries (vocabulary depth), and the connection strength between lexical representations (semantic relatedness); as such, it serves as an output for the decoding process and as an input for comprehension processes. Although different aspects of the lexicon can be distinguished, research on the role of the mental lexicon in reading comprehension often does not take these individual aspects of the lexicon into account. The current study used a multicomponent approach to examine whether measures of spoken and written vocabulary breadth, vocabulary depth, and semantic relatedness were differentially predictive of individual differences in reading comprehension skills in fourth-grade students. The results indicated that, in addition to nonverbal reasoning, short-term memory, and word decoding, the four measures of lexical quality substantially added (30 %) to the proportion of explained variance of reading comprehension (adding up to a total proportion of 65 %). Moreover, each individual measure of lexical quality added significantly to the prediction of reading comprehension after all other measures were taken into account, with written lexical breadth and lexical depth showing the greatest increase in explained variance. It can thus be concluded that multiple components of lexical quality play a role in children’s reading comprehension.
