The goal of this longitudinal study was to examine how lexical quality predicts the emergence of literacy abilities in 169 Dutch kindergarten children before formal reading instruction has started. At the beginning of the school year, a battery of precursor measures associated with lexical quality was related to the emergence of letter knowledge…

This study explored the background knowledge (BK) and reading comprehension (RC) relationship for struggling adult readers. Using confirmatory factor analyses, a single-factor BK model exhibited better fit than a two-factor model separating academic knowledge and general information, which indicates that BK represents a unidimensional construct…

The purpose of this study was to investigate the impact of inference making, decoding, memory, and vocabulary on reading comprehension among 7th- through 12th-grade struggling readers with varying levels of inattention and hyperactivity. We categorized a group of 414 struggling readers into 3 groups based on results from factor mixture modeling:…

This study examined the similarities and differences in the functioning of component processes underlying first language (L1) and second language (L2) word reading in Chinese. Fourth-grade Chinese children in Singapore were divided into L1 and L2 reader groups based on whether they used Mandarin or English as their home language. Both groups were…

Fluent readers can read connected text with accuracy, automaticity, and prosody. Without practice, automaticity cannot develop in reading, and readers must focus their attention on decoding, limiting their ability to simultaneously comprehend. Researchers have traditionally assumed that fluency and comprehension have a unidirectional relationship…

Early behavioral self-regulation is an important predictor of the skills children need to be successful in school. However, little is known about the mechanism(s) through which self-regulation affects academic achievement. The current study investigates the possibility that two aspects of children's social func- tioning, social skills and problem…

Children diagnosed with cerebral palsy (CP) often show difficulties in arithmetic compared to their typically developing peers. The present study explores whether cognitive and motor variables are related to arithmetic performance of a large group of primary school children with CP. More specifically, the relative influence of non-verbal…

The purpose of the present study was twofold: First, the authors investigated if an extended version of the component model of reading (CMR; Model 2), including decoding rate and oral vocabulary comprehension, accounted for more of the variance in reading comprehension than the commonly used measures of the cognitive factors in the CMR. Second,…

This exploratory study examined the influences of student, teacher, and setting characteristics on kindergarteners' early reading outcomes and investigated whether those relations were moderated by type of intervention. Participants included 206 kindergarteners identified as at risk for reading difficulties and randomly assigned to one of two…

The reauthorization of the Individuals with Disabilities Education Act has initiated changes that are affecting early literacy assessment, and it has prompted the growing use of measures that incorporate phonological and alphabetic fluency. However, the question of how phonological and alphabetic fluency can inhibit (or promote) reading…

Purpose: To demonstrate that early childhood speech sound disorders (SSD) and later school-age reading, written expression, and spelling skills are influenced by shared endophenotypes that may be in part genetic. Method: Children with SSD and their siblings were assessed at early childhood (ages 4-6 years) and followed at school age (7-12 years).…

In this study an attempt was made to construct a multi-factor model predicting the development of reading literacy in the upper grades of primary school in the Netherlands for subgroups of 729 first language (L1) learners and 93 second language (L2) learners. Following a longitudinal design, it was explored to what extent the variation in reading…

The authors examined second grade reading accuracy and fluency and their associations via letter knowledge to phonological and language predictors assessed at 3.5, 4.5, and 5.5 years in children in the Jyvaskyla Longitudinal Study of Dyslexia. Structural equation modeling showed that a developmentally highly stable factor (early phonological and…

Examined the joint and unique predictive significance of emergent literacy skills for later emergent literacy skills and reading in two samples of preschoolers. Structural equation modeling revealed significant developmental continuity of these skills, particularly for letter knowledge and phonological sensitivity from late preschool to early…
