There is an ongoing debate whether phonological deficits in dyslexics should be attributed to (a) less specified representations of speech sounds, like suggested by studies in young children with a familial risk for dyslexia, or (b) to an impaired access to these phonemic representations, as suggested by studies in adults with dyslexia. These…

Reading difficulties of children growing up in poverty contexts have not received as much attention as those of children from middle-income families. This paper analyzes the reading-related cognitive profiles of Argentine, Spanish-speaking, low-SES children with reading difficulties (RD), by comparing them with chronological age- (CA) and reading…

We examined how Planning, Attention, Simultaneous and Successive (PASS) processes predict reading comprehension in a sample of university students (Study 1) and what PASS processes distinguish adults with and without reading difficulties (Study 2). In Study 1, 128 university students were tested on Das-Naglieri Cognitive Assessment System, reading…

Purpose: The objective of this study was to assess and compare the predictive values of group membership for rapid automatized naming (RAN) and phonemic awareness (PA) in Dutch school children with and without reading disabilities (RD) or specific language impairment (SLI). Method: A composite word reading index and a formal SLI diagnosis were…

It has been argued that children with learning disabilities (LD) encounter severe problems in working memory (WM) tasks, especially when they need to update information stored in their WM. It is not clear, however, to what extent this is due to a generally poor updating ability or to a difficulty specific to the domain to be processed. To examine…

Difficulties suppressing previously encountered but currently irrelevant information from working memory characterize less skilled comprehenders in studies in which they are matched to skilled comprehenders on word decoding and nonverbal IQ. These "extreme" group designs are associated with several methodological issues. When sample size…

This handbook presents a wide range of research on adults who have low literacy skills. It looks at the cognitive, affective, and motivational factors underlying adult literacy; adult literacy in different countries; and the educational approaches being taken to help improve adults' literacy skills. It includes not only adults enrolled in adult…

This study investigated the impact of cognitive strategy instruction (CSI) on mathematical word problem solving of students with mathematics disabilities. A sample of fourth-grade students in a Chinese primary school was divided into a treatment group (75 students) and a comparison group (75 students). The sample consisted of students with…

The present study aimed to examine the nature of the working memory and general cognitive ability deficits experienced by university students with a specific reading comprehension deficit. A total of 32 university students with poor reading comprehension but average word-reading skills and 60 age-word-matched controls with no comprehension…

No previous empirical study has investigated whether the learning disabilities (LD) identification decisions of proposed methods to operationalize processing strengths and weaknesses approaches for LD identification are associated with differential treatment response. We investigated whether the identification decisions of the…

This article reviews the results of a meta-analysis of the experimental published literature that compares the academic, cognitive, and behavioral performance of adults with reading disabilities (RD) with average achieving adult readers. The meta-analysis shows that deficits independent of the classification measures emerged for adults with RD on…

When skilled readers read briefly-presented word pairs, they produce between-word errors, in which letters migrate between neighboring words (e.g., "mild wind" can be misread as "wild mind"). Such errors are also produced by individuals with attentional dyslexia, even without time limitation. In this study, we tested several aspects of skilled…

Controversy still exists over whether there is a magnocellular deficit associated with developmental dyslexia. Here we utilised a magnocellular system-biased phantom contour form discrimination task defined by high temporal frequency contrast reversals to compare contrast sensitivity in a group of children with dyslexia and an age- and nonverbal…

The purpose of this quasi-experimental study was to compare the cognitive performance of 11-to 14-year-old children with reading disabilities as a function of high (greater than 85 reading standard score) and low (less than 85 reading standard score) response to intervention. Students were divided into high responders, low responders, and…

This study aims to investigate the relation of syntactic and discourse skills to morphological skills, rapid naming, and working memory in Chinese adolescent readers with dyslexia and to examine their cognitive-linguistic profiles. Fifty-two dyslexic readers (mean age, 13;42) from grade 7 to 9 in Hong Kong high schools were compared with 52…
