Mathematical disabilities (MD) have a negative life-long impact on professional success, employment, and health outcomes. Yet little is known about the intrinsic functional brain organization that contributes to poor math skills in affected children. It is now increasingly recognized that math cognition requires coordinated interaction within a…

Research on individual differences in second language (L2) reading ability has primarily focused on factors known to contribute to first language (L1) reading ability, with little consideration of factors mediating interference between languages. In an exploratory analysis, we compared the degree to which the linguistic interference that readers…

We examined reading comprehension in children with ADHD by assessing their ability to build a coherent mental representation that allows them to recall central and peripheral information. We compared children with ADHD (mean age 9.78) to word reading-matched controls (mean age 9.89) on their ability to retell a passage. We found that even though…

The relations between reading, auditory, speech, phonological and tactile spatial processing are investigated in a Dutch speaking sample of blind braille readers as compared to sighted print readers. Performance is assessed in blind and sighted children and adults. Regarding phonological ability, braille readers perform equally well compared to…

The ability to learn visual-phonological associations is a unique predictor of word reading, and individuals with developmental dyslexia show impaired ability in learning these associations. In this study, we compared developmentally dyslexic and nondyslexic adults on their ability to form cross-modal associations (or "bindings") based…

This dissertation is a phenomenological case study of two 12th grade English/language arts (ELA) classrooms where teachers used graphic novels with their advanced students. The primary purpose of this case study was to gain insight into the phenomenon of using graphic novels with these students--a research area that is currently limited.…

An experiment with random assignment examined the effectiveness of a strategy to learn unfamiliar English vocabulary words during text reading. Lower socioeconomic status, language minority fifth graders (M = 10 years, 7 months; n = 62) silently read eight passages each focused on an unknown multi-syllabic word that was underlined, embedded in a…

Recent studies have shown that children with mathematics difficulties (MD) have weaknesses in multiple areas of mathematics. Andersson, for example, recently found that children with MD perform significantly worse than other children on clock reading tasks. The present study builds on this recent finding and aims at a more profound understanding…

Early reading and spelling abilities in children from Ireland and Sweden with severe speech and physical impairment (SSPI) were studied and compared. The aim was to look for similarities as well as for differences that could be related to the different linguistic environments. Both group consisted of 15 children, and were matched on linguistic…

Developmental dyscalculia (DD) is a deficit in number processing and arithmetic that affects 3-6% of schoolchildren. The goal of the present study was to analyze cerebral bases of DD related to symbolic number processing. Children with DD aged 9-11 years and matched children with no learning disability history were investigated using fMRI. The two…

This study investigated the effects of syntactic complexity on written sentence comprehension in compensated adults with dyslexia. Because working memory (WM) plays a key role in processing complex sentences, and individuals with dyslexia often demonstrate persistent deficits in WM, we hypothesized that individuals with dyslexia would perform more…

Very few studies have directly compared reading acquisition across different orthographies. The authors examined the concurrent and longitudinal predictors of word decoding and reading fluency in children learning to read in an orthographically inconsistent language (English) and in an orthographically consistent language (Greek). One hundred ten…

Examined whether age-related working memory deficits in learning disabled (LD) readers across four age groups (7, 10, 13, and 20) reflected retrieval efficiency or storage capacity problems. Found that LD readers' working memory performance was inferior to skilled readers' on verbal and visual-spatial working memory tasks across all ages.…

Skilled and unskilled readers from grades 3, 5, and 7 performed one of three memory tasks on a randomized list of primary word associates. Examined reading skill differences in relation to memory skills. (BD)

Matched groups of normal and retarded readers were required to perform same/difference judgments in which the interval between standard and comparison stimuli was either 0, 1, or 6 seconds. (BRT)
