This study examined the roles of first-language (L1) Chinese and second-language (L2) English phonological skills in English and Chinese reading comprehension, respectively, and their association with reading comprehension difficulties among Hong Kong Chinese-English bilingual children. We tested 258 second graders on nonverbal intelligence,…

Working memory (WM) is a recognised component of executive function and has undergone scrutiny in terms of bilingual and monolingual performance comparisons. Research to date, however, has not consistently replicated the presence of bilingual advantage. The present study examined short-term (STM) and WM in immersion-educated children and a matched…

Purpose: Classifying children into two language ability groups, with and without language impairment, may underestimate the number of groups with distinct language ability patterns, or, alternatively, there may be only a single group characterized by a continuum of language performance. The purpose of the current study was to identify the number…

It is frequently assumed that deaf individuals have superior visual-spatial abilities relative to hearing peers and thus, in educational settings, they are often considered visual learners. There is some empirical evidence to support the former assumption, although it is inconsistent, and apparently none to support the latter. Three experiments…

The aim of the present study was to empirically disentangle the interdependencies of the impact of nonverbal intelligence, working memory capacities, and phonological processing skills on early reading decoding and spelling within a latent variable approach. In a sample of 127 children, these cognitive preconditions were assessed before the onset…

Differing etiological explanations have been proposed to account for poor comprehenders' difficulties with reading comprehension, with some researchers emphasizing working memory deficits and others arguing for oral language weaknesses playing a key causal role. The authors contrasted these two theoretical accounts using data obtained from direct…

We investigated effects of listening to single or multiple storybook readings versus testing with and without feedback on children's breadth (i.e., the number of words) and depth (i.e., the quality of word knowledge) of vocabulary learning. Kindergartners (n = 125) were divided into 3 intervention and 1 control conditions. Children in the control…

This study explored factors that are associated with calculation development among 176 children at-risk for learning difficulties. Data were collected on working memory, language, non-verbal reasoning, processing speed, decoding, numerical competence, incoming calculation, SES, and gender at the beginning of 1st grade and on calculations over 4…

Forty native Spanish-speaking children (age 8;0-10;3), 20 with Specific Language Impairment (SLI) and 20 with Typical Language Development (TLD), received a battery of psycholinguistic tests, IQ, hearing screenings, and the Spanish Non-word Repetition Task (NRT). The children's repetition of 20 non-words was scored. The percentage of correct…

This study investigated whether the role of working memory capacity varies over the course of second language (L2) morphosyntactic development. Eighty-seven beginning, intermediate, and advanced university L2 Spanish learners completed two nonverbal tasks measuring executive function (EF) and phonological working memory (PWM) in their native…

Executive functions (EFs) and intelligence were examined concurrently and longitudinally in 126 preschool children. EF was assessed using the Flexible Item Selection Task (FIST) and the Behavior Rating Inventory of Executive Function-Preschool Version (BRIEF-P). Children's intelligence was assessed using the Verbal and Performance subtests from…

The current study investigated the cause of the reported problems in working memory in children with reading difficulties. Verbal and visuospatial simple and complex span tasks, and digit span and reaction times tasks performed singly and in combination, were administered to 46 children with single word reading difficulties and 45 typically…

The current study tested 2 models of inhibition in 45 children with language impairment and 45 children with normally developing language; children were aged 7 to 12 years. Of interest was whether a model of inhibition as a mental-control process (i.e., executive function) or as a mental resource would more accurately reflect the relations among…

The focus of the present study was on the mediation and moderation effects of reading processes as evidenced from eye movements on the relation between cognitive and linguistic student characteristics (word decoding, vocabulary, comprehension skill, short-term memory, working memory, and nonverbal intelligence) and text comprehension. Forty 4th…

This study examined the Chinese written composition development of elementary-grade students in relation to the simple view of writing. Measures of nonverbal reasoning ability, component skills of transcription (stroke sequence knowledge, word spelling, and handwriting fluency), oral language (definitional skill, oral narrative skills, and…
