The study of Hebrew, a non-European language written in a non-alphabetic (abjadic) script offers valuable insights into the science of reading beyond the well-studied alphabetic scripts. Because reading development in Hebrew is shaped by the uniquely Semitic root-and-pattern morphology and the abjadic (predominantly consonantal) orthography, our…

Quasiregular orthographies such as English contain substantial ambiguities between orthography and phonology that force developing readers to acquire flexibility during decoding of unfamiliar words, a skill referred to as a "set for variability" (SfV). The ease with which a child can disambiguate the mismatch between the decoded form of…

By investigating children whose parents have dyslexia, family risk (FR) studies are expanding our understanding of the intergenerational transmission of dyslexia. These studies, however, vary in their identification of FR, and how the use of different identification methods influences research findings and conclusions is yet to be systematically…

Arguably, the classroom teacher is an important factor, if not the most important factor, in helping students with dyslexia to read and write well, yet there is little known about whether teachers perceive that they have the knowledge and confidence to teach these students. The present study was a national online survey of schools in Aotearoa New…

While previous research has documented the unique aspects of Chinese dyslexia as compared to dyslexia in alphabetic scripts, it remains unclear whether the difference in Chinese literacy experiences influences the manifestation of Chinese dyslexia. The present article first reviews the characteristics of Chinese languages and scripts, including…

In this article, I provide an examination of research evidence concerning the effects of classroom instruction (Tier 1) for students with dyslexia and other reading problems. I discuss the suitability and limitations of different types of research evidence that may be used to determine how best to support the learning of these students in the…

The author argues that despite the vast proliferation of scientific research, our understanding of dyslexia is marked by serious weaknesses of conceptualization, definition, and operationalization that are not only unscientific but also result in impoverished practice in schools, social inequity in both understanding and provision for many…

This study examined the processing of derivational morphology and its association with early phonological skills of 24 Dutch-speaking children with dyslexia and 46 controls matched for age. A masked priming experiment was conducted where the semantic overlap between morphologically related pairs was manipulated as part of a lexical decision task.…

It is widely recognized that individuals with dyslexia have difficulties with word reading and spelling, and individuals with reading comprehension difficulties have low vocabulary knowledge. However, little is known about the extent to which spelling and vocabulary are informative of reading difficulties. In the present study, we investigated…

This meta-analysis included experimental or quasi-experimental intervention studies conducted between 1980 and 2020 that aimed to improve reading outcomes for Grade K-5 students with or at risk for dyslexia (i.e., students with or at risk for word reading difficulties, defined as scoring at or below norm-referenced screening or mean baseline…

The purpose of this paper is to describe what we know and what we still need to learn about literacy intervention for children who experience significant difficulties learning to read. We reviewed 14 meta-analyses and systematic reviews of experimental and quasi-experimental studies published in the last decade that examined the effects of reading…

Definitions of dyslexia typically make reference to unexpected poor reading, although how best to operationalize unexpected remains an issue. When operationally defined as reading below expectations based on the level of oral language, cases of unexpected poor reading make up fewer than half of cases of poor reading, and cases of unexpected poor…

To learn to read, the brain must repurpose neural systems for oral language and visual processing to mediate written language. We begin with a description of computational models for how alphabetic written language is processed. Next, we explain the roles of a dorsal sublexical system in the brain that relates print and speech, a ventral lexical…

Oral deaf children and hearing children with dyslexia both experience literacy challenges, although their reasons differ. The authors explored the problems underlying poor literacy in each group and drew implications for reading interventions. Data were collected using standardized literacy and phonological measures from 69 severe-to-profoundly…

The aim of this study was to investigate verbal and nonverbal cognitive deficits in Italian students with developmental dyslexia. The performances of 32 dyslexic students, 64 age-matched typically reading controls, and 64 reading age-matched controls were compared on tests of lexical knowledge, phonological awareness, rapid automatized naming,…
