Understanding of the complement principle has been proposed as closely related to computational skills, but few studies have investigated their interrelations. The present longitudinal study attempted to clarify the picture by examining their potential cross-lagged relation. Fourth graders (n = 221) in Hong Kong received 3 cognitive assessments at…

Students' understanding of the meaning of the equal sign develops slowly over the primary grades. In addition to updating their representations of equations to recognize that the equal sign represents an equivalence relation rather than signaling an operation, students need to move beyond full computation to efficiently solve equivalence problems.…

The importance of early childhood narrative skills in social relationships and children's internal capacity is of utmost interest to be studied. This aim of this study is to examine how the social group functioning, narrative skills, school success and non-verbal intelligence are interconnected. This is a mixed design study with a sample of 109…

Skilled reading requires fast and accurate access to previously encountered words stored in memory. Yet, little research addresses skills that support such lexical access. Based on theoretical predictions, one skill that may support lexical access is orthographic knowledge. Thus, our goal was to investigate the relation between lexical access and…

Purpose: This study examined language group differences in English syntactic knowledge based on performance on a sentence repetition task. Method: Fourth and sixth grade students who were monolinguals (n = 30), early bilinguals (i.e., simultaneous; n = 27), or late bilinguals (i.e., sequential; n = 29) completed an English sentence repetition…

The effects of transcription skills, comprising both spelling and handwriting fluency, on sentence writing among young Chinese as a second language (CSL) learners were evaluated and compared to those of reading and oral language using a one-year longitudinal study design. Various writing models postulated that transcription skills are essential in…

The present study examines the concurrent relationship between morphological awareness and vocabulary breadth and depth after accounting for the effect of other potential contributors. A sample of French-speaking fourth-grade children who spoke either French at home (L1) (n = 55) or another language (L2) (n = 85) completed a number of tests…

We aimed to investigate the effects of phonological awareness -- PA, rapid automatised naming -- RAN, visuospatial and verbal working memory -- WM and executive functions -- EF on the reading and arithmetic skills of children with low- to medium-performance levels. Participants were 472 Brazilian children from 3rd to 5th grades. Quantile…

Reading comprehension is a complex task requiring many underlying skills. Syntactic awareness and morphological awareness are two such skills that have been shown to be related to reading comprehension. However, the majority of studies have been carried out in English, and very few have explored these skills in monolingual Spanish speaking…

This study examined whether syntactic awareness was related to reading comprehension difficulties in either first language (L1) Chinese or second language (L2) English, or both, among Hong Kong Chinese-English bilingual children. Parallel L1 and L2 metalinguistic and reading measures, including syntactic word-order, morphological awareness,…

The goal of the paper was to investigate whether morphological units -- stems and suffixes -- influence orthographic processing by modulating visual attention demands to the task. Orthographic processing was measured with a visual one-back task requiring letters to be detected within pseudowords not including stems/suffixes, or containing real…

This study's primary purpose was to identify predictors of response to a multi-component reading comprehension intervention in a sample of poor readers in grades 4-5. Additional study aims were to explore (a) the utility of various methods (e.g., "growth" versus "final status") and measures (e.g., "near-transfer"…

Background: Reading comprehension is a complex process influenced by many factors. However, the abilities that are known to influence reading comprehension may not contribute equally for children with different levels of oral language. Aims: Here we examined the relationship of two factors known to influence reading comprehension (morphology and…

Background: Physically manipulating objects according to texts can improve reading performance. This study examined whether these benefits can also be achieved via observing these manipulations or whether, because of an additional involvement of an action system, the physical manipulation might induce larger effects. Methods: In total, 134 second…

Response to intervention (RTI) has been promoted for nearly 20 years as a valid supplement to or alternative method of learning disability (LD) identification. Nevertheless, important unresolved questions remain about its role in disability identification. We had two purposes when conducting this study of 229 economically and racially diverse poor…
