This study aims to understand individual differences between children in metacognitive monitoring and control processes and the developmental trajectories of metacognition over one year. Three indicators of procedural metacognition were used: monitoring accuracy (discrimination of confidence judgments between correct and incorrect test responses),…

This longitudinal study investigated development of second language (L2) reading comprehension ability and predictive contributions of five L2 reading components (word recognition speed, listening comprehension, vocabulary breadth, grammar knowledge and first language [L1] reading comprehension) using latent growth curve modelling. The…

Foreign language education has now been implemented at the elementary school level across Europe, and early foreign language education has gained traction following language policies set by the European Commission. The long-term effects of an early start, however, have not received ample scientific scrutiny. The present study assessed early…

In this 8-year longitudinal study, we traced the vocabulary growth of Chinese children, explored potential precursors of vocabulary knowledge, and investigated how vocabulary growth predicted future reading skills. Two hundred and sixty-four (264) native Chinese children from Beijing were measured on a variety of reading and language tasks over…

Adults demonstrate difficulty and pronounced variability when developing second language (L2) grammatical knowledge and reading skills. We examine explanations in terms of individual differences in working memory (WM). Despite numerous studies, the association between WM and adult second language (L2) acquisition remains unclear, and longitudinal…

Cunningham and Stanovich reported a longitudinal investigation over 10 years that examined the unique influence of exposure to print in explaining individual differences on various measures of reading achievement and declarative (general) knowledge. The present study replicated their investigation with a larger number of participants and…

Modern behavior-genetic studies of twins in the United States, Australia, Scandinavia, and the United Kingdom show that genes account for most of the variance in children's reading ability by the end of the 1st year of formal reading instruction. Strong genetic influence continues across the grades, though the relevant genes vary for reading words…

This study investigated predictors of word reading and reading comprehension skills using longitudinal data from Spanish-speaking kindergartners (N = 163) and first grade students (N = 305) from high SES families in Chile. Individual differences in letter-naming fluency and phonemic segmentation fluency, but not vocabulary, were positive…

Authors examined the relationship between individual differences in L1 print exposure and differences in early L1 skills and later L2 aptitude, L2 proficiency, and L2 classroom achievement. Participants were administered measures of L1 word decoding, spelling, phonemic awareness, reading comprehension, receptive vocabulary, and listening…

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…

Longitudinal structural equation modeling was used to evaluate longitudinal relationships across adjacent grade levels 1 to 7 for levels of language in writing (Model 1, subword letter writing, word spelling, and text composing) or writing and reading (Model 2, subword letter writing and word spelling and reading; Model 3, word spelling and…

Tested the hypothesis that individual differences in reading ability increase over time, by assessing children, at seven occasions between kindergarten and third grade, on various measures of reading ability, reading behavior, and attitudes toward reading. Found that individual differences among children in word recognition, but not reading…

Studied reading comprehension, vocabulary, general knowledge, and print exposure of 11th graders who completed reading battery 10 years earlier. Found that first-grade reading ability predicted all 11th-grade outcomes--even when cognitive ability was partialed out--and was linked to print exposure, even after 11th-grade reading comprehension…
