We propose a review of the literature of the studies investigating reading acquisition in intellectual deficiency (ID), with particular focus on the explanatory factors for reading difficulties. Indeed, we explore the role of intellectual efficiency, perceptual abilities, oral language development, phonological processing and memory. The study of…

Learning to read in any language requires learning to map among print, sound and meaning. Writing systems differ in a number of factors that influence both the ease and the rate with which reading skill can be acquired, as well as the eventual division of labor between phonological and semantic processes. Further, developmental reading disability…

Patients with letter-by-letter alexia may have residual access to lexical or semantic representations of words despite severely impaired overt word recognition (reading). Here, we report a multilingual patient with severe letter-by-letter alexia who rapidly identified the language of written words and sentences in French and English while he had…

This review explores the literacy difficulties experienced by prelingual, profoundly deaf, sign-dominant adults. A critical overview of the existing literature identifies the importance of understanding their language experiences and word-coding preferences. Findings challenge the notion that a permanent lack of audition from birth prevents…

Reading disabilities such as dyslexia, a specific learning disability that affects an individual's ability to process written language, are estimated to affect 15-20% of the general population. Consequently, elementary school teachers encounter students who struggle with inaccurate or slow reading, poor spelling, poor writing, and other language…

An increasing number of students are being diagnosed with auditory processing disorder (APD), but the school psychology literature has largely neglected this controversial condition. This article reviews research on APD, revealing substantial concerns with assessment tools and diagnostic practices, as well as insufficient research regarding many…

Background: Fast ForWord is a suite of computer-based language intervention programs designed to improve children's reading and oral language skills. The programs are based on the hypothesis that oral language difficulties often arise from a rapid auditory temporal processing deficit that compromises the development of phonological…

A proportion of children with visual impairments have specific reading difficulties that cannot be easily explained. This article reviews the data on problems with braille reading and interprets them from the framework of the temporal-processing deficit theory of developmental dyslexia.

This study explores the nature of orthographic processing skills among French-speaking children in Grades 6 and 8 who are learning English at school as a second language (L2). Two aspects of orthographic processing skills are thought to form a convergent construct in monolingual beginning readers: word-specific knowledge (e.g. "rain-rane") and…

According to Gough and Tunmer's Simple View of Reading, Reading Comprehension = Decoding (D) x Listening Comprehension (C). The purpose of this study was to evaluate the model with a sample of First Nations children, known to have average decoding and listening comprehension but poor reading comprehension. In addition, the authors examined the…

Our goal was to investigate auditory and speech perception abilities of children with and without reading disability (RD) and associations between auditory, speech perception, reading, and spelling skills. Participants were 9-year-old, Finnish-speaking children with RD (N = 30) and typically reading children (N = 30). Results showed significant…

When preparing to perform a task, the brain settles into task-set states which are relevant for the selection of the appropriate task-rules and stimulus-response mappings. The way this selection takes place within the Language domain is not well understood. We used high-density electrophysiological recordings while participants were engaged in a…

The double-deficit hypothesis (DDH) of developmental dyslexia was investigated in seven to twelve year old Spanish children. It was observed that the double deficit (DD) group had the greatest difficulty with reading.

Children (n = 122) and adults (n = 200) with dyslexia completed rapid automatic naming (RAN) letters, rapid automatic switching (RAS) letters and numbers, executive function (inhibition, verbal fluency), and phonological working memory tasks. Typically developing 3rd (n = 117) and 5th (n = 103) graders completed the RAS task. Instead of analyzing…

In the influential "simple view of reading" (Gough & Tunmer, 1986), Reading Comprehension (R) = Decoding (D) x Linguistic Comprehension (C). To evaluate this model, this article explores the performance of 15-year-olds with severe reading delays. Results showed that D and C described reading comprehension better than D and verbal cognitive ability…
