In this paper, Emeritus Professor Kevin Wheldall AM, who received the Eminent Researcher Award of this journal in 2023, describes his research over the past five decades, together with his wife and research partner Dr Robyn Wheldall. Following a biographical sketch, selected research is reviewed successively over five decades on language,…

Conceptual knowledge goal (CKG) is a typical component of outcome-based learning. However, the contribution of CKG to poor readers' reading comprehension development remains unclear. Following the suggestion of the Simple View of Reading theory for the poor reader category, the current study recruited 90 poor decoders (PD), 76 poor comprehenders…

Developmental dyslexia (DD) is a common reading disability, affecting 5% to 11% of children in North America. Children classified as having DD often have a history of early language delay (ELD) or language impairments. Nevertheless, studies have reported conflicting results as to the association between DD-ELD and the extent of current language…

We explored reading comprehension development in children on the spectrum from pre-school to the first (YOS1) and third year of schooling (YOS3). Children were first assessed on meaning-related skills in pre-school. Forty-one children completed follow-up assessments of reading comprehension, reading accuracy, and listening comprehension in YOS1.…

This study compared the sentence hyperbole comprehension performance of Chinese poor readers with various levels of arithmetic proficiency. A total of 168 Chinese poor readers in Grade 1 were recruited, and their nonverbal intelligence, verbal working memory, Chinese receptive vocabulary, Chinese grammatical knowledge, character reading and…

In Canada, approximately 12% of school-aged children are enrolled in French Immersion (FI), with some provinces estimating close to 30%. FI programs are intended to produce bilingual individuals who can functionally communicate in both of Canada's official languages. Yet, we are currently underinformed as to how to identify children with French…

Children with autism spectrum disorder (ASD) and hyperlexia (HPL) have both advanced word reading skills and a reading comprehension disorder, alongside impaired oral language. We developed a unique, parent-supported, tablet-based intervention aiming to improve oral and reading comprehension at the word-, phrase- and sentence-level, for…

Word semantic knowledge (WSK) is crucial to the development of one's reading comprehension ability. A total of 608 students (208 poor readers in the experimental group and 200 poor readers in the control group one, and 200 typical readers in control group 2) from grade 4 participated in this study. Selected reading ability assessments were…

Background: The purpose of this study was to examine the relationship between selective visual attention (SVA), reading decoding, listening comprehension and reading comprehension in children with and without a reading disorder. Methods: We used longitudinal data from the Avon Longitudinal Study of Parents and Children. We split children into four…

Purpose: Multiple factors impact reading acquisition in individuals with reading disability, including genetic disorders such as Williams syndrome (WS). Despite a relative strength in oral language, individuals with WS usually have an intellectual disability and tend to display deficits in areas associated with reading. There is substantial…

Purpose: This was an investigation of the dimensionality of oral and written language to test the hypothesis that a two-factor model with sound/word and sentence/discourse language levels would best fit language and literacy data for a population-based sample in the school-age years. Method: A stratified secondary data set of 1,500 participants…

The present study examined the reading comprehension and receptive vocabulary skills of children with poor reading comprehension despite adequate decoding using a regression-based matching technique. Participants included five cohorts of children who were identified as typical readers (N = 70,493 - 75,553) or as children with specific reading…

Reading and writing are distinct skill areas that influence each other across development. Children with autism spectrum disorder (ASD) are noted to exhibit challenges in both skill areas, though relatively few studies have examined relationships between reading and writing skills. This study adopted a reading-to-writing framework to examine if…

In this experimental study, we examined the effects of a technology-mediated intervention to improve students' understanding of academic vocabulary and its impact on measures of vocabulary and comprehension. The Vocabulators program was implemented in two states involving 24 teachers and 200 third-grade students identified as in need of…

Although reading outcomes for children with hearing loss are improving, too many of these children continue to display persistent reading difficulties. Because of these difficulties, there is an ongoing need to understand the nature of the relationships among decoding abilities, language skills, and reading achievement in this population more…
