This study investigated which components of the writing production process are impaired in Spanish children with developmental dyslexia (DD) aged 8 to 12 years. Children with and without dyslexia (n = 60) were assessed in their use of the lexical and the sublexical routes of spelling as well as the orthographic working memory system by…

In transparent orthographies like German, isolated learning disabilities in either reading or spelling are common and occur as often as a combined reading and spelling disability. However, most issues surrounding the cognitive causes of these isolated or combined literacy difficulties are yet unresolved. Recently, working memory dysfunctions have…

Using 4 years of mathematics achievement scores, groups of typically achieving children (n = 101) and low achieving children with mild (LA-mild fact retrieval; n = 97) and severe (LA-severe fact retrieval; n = 18) fact retrieval deficits and mathematically learning disabled children (MLD; n = 15) were identified. Multilevel models contrasted…

The purpose of this study was to examine the cognitive and academic profiles associated with learning disability (LD) in reading comprehension, word reading, applied problems, and calculations. The goal was to assess the specificity hypothesis, in which unexpected underachievement associated with LD is represented in terms of distinctive patterns…

Forty-four university students, of whom 11 had learning disabilities (LD), were tested on tasks requiring multisyllabic pseudoword repetition, oral reading, memory for digits, and vocabulary. In both LD and non-LD groups, significant correlations were found between pseudoword repetition accuracy and reading, suggesting that poor readers also have…

Analysis of data from 96 children in a longitudinal study found that foundation skills in speech perception and language as well as family demographics and home environmental variables were related to and predicted later reading scores. Event related potential measures of speech perception immediately after birth also predicted reading scores,…

This study investigated specific processing strengths and weaknesses among 75 readers, ages 6-10, with no oral language deficits. Unsuccessful readers of different ages showed similar information processing patterns, and differed from successful first-grade readers on short-term auditory/working memory and decoding/encoding. Three potential…

Forty children (ages five to nine) with or without reading disabilities, matched for mental age or reading age, completed a phoneme-grapheme learning task. Reading-disabled children took more trials than controls to learn correspondence pairs. Performance on the phonological processing task of short-term memory was the best predictor of overall…
