We examined whether word recognition accuracy and latency of words children encounter during primary school across the upper primary school grades can be predicted from word form (word length, mean Levenshtein distance, and mean frequency of neighbors), word meaning (free association network markers) and word exposure (corpus frequency and…

Enrichment programmes are designed to offer gifted students experiences that are not covered in the regular curriculum We used a pre-test-post-test control group design to examine the effects of a computer-based enrichment programme on the development of analytical and creative abilities in 26 gifted children in an experimental group (15 boys,…

This study is conducted to further understand the direct and indirect contributions of executive functioning (visuospatial updating, verbal updating, inhibition, shifting) and arithmetic fluency to mathematical problem-solving in 458 fourth-grade students. Arithmetic fluency along with visuospatial and verbal updating were significant predictors…

Background: Executive functions have been proposed to account for individual variation in reading comprehension beyond the contributions of decoding skills and language skills. However, insight into the direct and indirect effects of multiple executive functions on fifth-grade reading comprehension, while accounting for decoding and language…

Background: The present study examined patterns and predictors of reading comprehension growth in first language (L1) and second language (L2) readers in the upper grades of primary school. Previous research suggests that L1 and L2 readers differ in their growth trajectories and that differences in language proficiency play a role in this.…

In an experimental design, we investigated how fifth-grade readers use morphological and contextual information to infer the meaning of unknown words, and to what extent this is related to their cognitive and linguistic skills. A group of 166 fifth-grade Dutch children (59 L1, 107 L2) performed a lexical inferencing task in which the availability…

This study investigated macro-level navigation patterns in children's hypermedia learning, and how they related to task structure and learning outcomes. For this purpose, 5th and 6th grade learners performed a hypermedia assignment in which a high (n=57) versus a low (n=54) level of structure was provided. By means of qualitative analyses of their…

In lexical development, the specificity of phonological representations is important. The ability to build phonologically specific lexical representations predicts the number of words a child knows (vocabulary breadth), but it is not clear if it also fosters how well words are known (vocabulary depth). Sixty-six children were studied in…

Word knowledge acquisition is an incremental process that relies on exposure. As a result, word knowledge can broadly range from recognizing the word's lexical status, to knowing its meaning in context, and to knowing its meaning independent of context. The present study aimed to model incremental word knowledge in 1454 upper primary school…

The present study investigated responsiveness to intervention in children with an earlier versus later diagnosis of dyslexia. We examined differences between second (n=122; early diagnosis) and third (n=158; late diagnosis) graders with dyslexia on reading and spelling abilities before, during and after a dyslexia intervention as well as in…

In the present study, a 5-week tablet-based word reading efficiency game intervention (Reading Turbo) was integrated in a comprehensive phonics-based reading curriculum. The aims of the study were to examine whether the game would advance children's word reading efficiency, and to determine the extent to which pre-reading capacities and in-game…

The current research investigated the effectiveness of a narrative intervention method aiming to improve oral narrative ability in 8- to 10-year-old children with developmental language disorder (DLD) (n = 6). Oral narrative ability was assessed through a narrative retelling and a narrative generation task of which both the narrative…

Background: The lexical quality hypothesis proposes that successful reading comprehension requires high quality lexical representations, which allow for efficient retrieval. These retrieval operations have however not been specified. Methods: We investigated the contribution of semantic retrieval to reading comprehension in 119 Dutch children in…

This study investigated in a longitudinal design how 74 Dutch children with dyslexia and 39 typically developing peers differed in sequential versus spatial implicit learning and overnight consolidation, and it examined whether implicit learning related to (pseudo)word reading development in Grades 5 and 6. The results showed that sequential, but…

Text reading prosody and reading comprehension are related, but both rely on decoding. The aim of the current study was, therefore, to disentangle the contribution of decoding from that of prosody skills. We examined the performance on text reading prosody and speech prosody in fifth-grade children with age-appropriate decoding but weak…
