Dyslexia is a term widely used to describe reading characterised by problems with the fluent and accurate letter or word recognition. Nevertheless, there is no consensus about the definition, origin, and diagnosis of dyslexia and the term is often used very differently by researchers and practitioners. In many cases, research findings are employed…

In this pilot study, we evaluated the effects of the online computer-based training programme 'Lexilogy-Greek' on the reading and spelling performance of young poor readers and spellers. The training is based on psycholinguistic principles that emphasise the importance of acquiring efficient phonological as well as morphological knowledge in…

Despite data supporting the benefits of early reading interventions, there has been little evaluation of the long-term educational impact of these interventions, with most follow-up studies lasting less than 2 years (Suggate, 2010). This study evaluated reading outcomes more than a decade after the completion of an 8-month reading intervention…

Research consistently demonstrates that attention deficits have a deleterious effect on academic achievement. Impairments in attention, and not hyperactivity/impulsivity, are associated with learning difficulties and academic problems in students with attention-deficit/hyperactivity disorder (ADHD). To date, most studies have focused on symptoms…

Background: Medication treatment studies of ADHD have typically not assessed effects on reading performance, although reading difficulties frequently co-occur in children with ADHD. The current study characterizes the effects of lisdexamfetamine dimesylate (LDX; Vyvanse[R], Shire US Inc.), at peak efficacy, on reading performance in children with…

Some children demonstrate adequate or better reading achievement in early school grades but fall significantly behind their peers in later grades. These children are often referred to as late-emerging poor readers. In this study, we investigated the prevalence and heterogeneity of these poor readers. We also examined the early language and…

The present study investigated whether (a) growth patterns related to cognitive processing (working memory, updating, inhibition) differed in subgroups of children with reading disabilities (RD) and (b) growth in working memory (executive processing) predicted growth in other cognitive areas, such as reading and math. Seventy-three children (ages…

Background: The marked degree of heterogeneity in persons with developmental dyslexia has motivated the investigation of possible subtypes. Attempts have proceeded both from theoretical models of reading and the application of unsupervised learning (clustering) methods. Previous cluster analyses of data obtained from persons with reading…

Attempts to evaluate the cognitive-motivational profiles of students with reading comprehension difficulties have been scarce. The purpose of the present study was twofold: (a) to assess the discriminatory validity of cognitive, motivational, affective, and psychopathological variables for identification of students with reading difficulties, and…

This study examines the usefulness of the Wechsler Intelligence Scale for Children-Revised (WISC-R) in predicting the reading achievement of 74 disabled readers in grade 3 on the word recognition subtest of the Wide Range Achievement Test (WRAT). The WRAT word recognition subtest was used because previous research has demonstrated a high positive…
