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…

This study examined the psychometric proprieties of the Arabic version of the Curriculum-Based Measurement Oral Reading Fluency (CBM ORF) for Jordanian students. A sample of 200 students (six to eight years old) was recruited from four public primary schools in Jordan. Results indicated that the CBM ORF had adequate reliability and validity…

High-performing adults with compensated dyslexia pose particular challenges to dyslexia diagnostics. We compared the performance of 20 multilingual Finnish university students with suspected dyslexia with 20 age-matched and education-matched controls on an extensive test battery. The battery tapped various aspects of reading, writing, word…

Comorbidity between SLI and dyslexia is well documented. Researchers have variously argued that dyslexia is a separate disorder from SLI, or that children with dyslexia show a subset of the difficulties shown in SLI. This study examines these hypotheses by assessing whether family history of dyslexia and speech and language difficulties are…

We surveyed students enrolled in Introductory Psychology courses about their text marking preferences and analyzed the marking in their textbooks. Low-skill readers report more reliance on highlighting strategies and actually mark their texts more than better readers. In addition, low-skilled readers prefer to buy used, previously marked texts…

The purpose of this study was to evaluate rapid automatized naming skills (RAN) and immediate memory processes in 243 Chinese Mandarin-speaking elementary readers (ranging from Grade 1 to Grade 5). For RAN subtests, the mean naming time decreased monotonically with grade level in good and average readers, and a similar trajectory was found in poor…

The purpose of this study was to examine the efficacy of using thematic units in small group instructional settings for struggling readers to increase oral language in the areas of receptive, expressive, and written vocabulary. This research examined the efficacy of using thematic units in small group instructional settings for struggling readers…

Background: Readability tests are indicators that measure how easy a document can be read and understood. Simple, but very often ignored, readability statistics cannot only provide information about the level of difficulty of the readability of particular documents but also can increase an evaluator's credibility. Purpose: The purpose of this…

We compared processing of non-verbal auditory stimuli by dyslexic and non-dyslexic children using electrophysiological methods. The study included 39 children (17 with dyslexia plus 22 controls) assessed via frontal, central, parietal, and temporal electrodes. As an extension of previous P300 event-related potential studies, we analysed variations…

Children with learning disorders (LD) are at increased risk for a host of psychosocial problems, including Attention Deficit Hyperactivity Disorder (ADHD) (e.g., Bouffard, Roy, & Vezeau, 2005; Elksnin & Elksnin, 2004; Greenham, 1999; Michaels & Lewandowski, 1990; Sideridis, Morgan, Botsas, Padeliadu & Fuchs, 2006; Weiner &…

One of the central challenges in mastering English is becoming sensitive to consistency from spelling to sound (i.e. phonological consistency) and from sound to spelling (i.e. orthographic consistency). Using functional magnetic resonance imaging (fMRI), we examined the neural correlates of consistency in 9-15-year-old Normal and Impaired Readers…

This article first describes two types of assessment (problem solving and standard treatment protocol) within a "responsiveness-to-instruction" framework to identify learning disabilities. It then specifies two necessary components (measures and classification criteria) to assess responsiveness-to-instruction, and present pertinent findings from…
