Background: The purported reciprocity between motivation and academic achievement in education has largely been supported by correlational data. Aims: Our first aim was to determine experimentally whether motivation and achievement are reciprocally related. The second objective was to investigate a potential behavioural mediation pathway between…

In the present study, it was hypothesized that the proportion of open questions teachers ask during shared book reading would be directly and indirectly (through class aggregated mean length of utterance) related to children's vocabulary and would be directly and indirectly (through class aggregated mean length of children's utterance and…

This study examined the unique contribution of Home Literacy Environment (HLE), Classroom Literacy Environment (CLE), and parent and teacher expectations to the development of Dutch (L1) and English (L2) vocabulary in children in Dutch-English bilingual primary education. The children (n = 106) were tested on vocabulary in both languages in…

We propose to use reading time as a metric to report progress in language learning applications. As a case study we use a web-based application that enables learners of a foreign language to read texts from the web and practice vocabulary with interactive exercises generated based on their past readings. The application captures generic…

Rejection by peers has devastating effects on children's social-cognitive development. As language difficulties have been found to be one of the underlying causes of peer rejection, the present study focused on the relation between these two variables. Specifically, this study was the first to test a hypothesized model connecting children's level…

The aim of this longitudinal study is to evaluate 3 views on the relationship between nonword repetition and vocabulary: (i) the storage-based view that considers nonword repetition, a measure of phonological storage, as the driving force behind vocabulary development, (ii) the lexical restructuring view that considers improvements in nonword…

Purpose: The aim of this study was to gain more insight into the linguistic characterization of dyslexia by investigating vocabulary acquisition. In a previous study, vocabulary at 17 months of age appeared to be related to familial risk (FR) of dyslexia. The aim of this study was to investigate how the differences in lexical composition further…

Research Findings: The present study compared effects of explicit instruction on and practice with the phonological form of words (form-focused instruction) versus explicit instruction on and practice with the meaning of words (meaning-focused instruction). Instruction was given via interactive storybook reading in the kindergarten classroom of…

This study investigates the relationship between nonword repetition (NWR) and vocabulary in 2-year-olds. Questions addressed are whether (1) NWR and vocabulary are associated, (2) phonotactic probability affects NWR, and (3) there is an interaction effect between phonotactic probability and vocabulary on NWR performance. The general aim of the…

We examined the developmental relations between knowledge of reading strategies and reading comprehension in a longitudinal study of 312 Dutch children from the beginning of fourth grade to the end of fifth grade. Measures for reading comprehension, reading strategies, reading fluency, vocabulary, and working memory were administered. A structural…

Difficulties in peer acceptance during elementary school have been associated with emotional and behavioural problems. This study used a randomized controlled intervention design to test whether improvements in peer acceptance mediated reduced rates of emotional and behavioural problems in intervention compared to control-group children. A total…

Purpose: The authors tested associations between (a) parent-reported temporary vs. persistent vocabulary delay and (b) parent-reported behavioral/emotional problems in a sample of 5,497 young Dutch children participating in a prospective population-based study. Method: Mothers completed the MacArthur Communicative Development…

The present study examined lexical richness in maternal input to Turkish preschool children in the Netherlands and the relationship with their vocabulary. Fifteen Turkish mother-child dyads were videotaped at the age of 3 and 4 in three settings: book reading, picture description and block building. Children's vocabulary in Turkish was measured at…

Novel word learning is reported to be problematic for children with severe language impairments (SLI). In this study, we tested electronic storybooks as a tool to support vocabulary acquisition in SLI children. In Experiment 1, 29 kindergarten SLI children heard four e-books each four times: (a) two stories were presented as video books with…

The associations between vocabulary growth and reading development were examined longitudinally for a representative sample of Dutch children throughout the elementary school period. Data on basic and advanced vocabulary, word decoding, and reading comprehension were collected across the different grades. The results showed significant progress on…
