Developmental dyscalculia (DD) is a mathematical learning disability that occurs in around 5%-7% of the population. At present, there are only a handful of screening tools to identify children that might be at risk of developing DD. The present study evaluated the classification accuracy of one such tool: The Numeracy Screener, a 2-min test of…

Introduction: The objective of this study is to find out if there are differences in selective and sustained attention between children with different subtypes of ADHD and children with learning disorders (LD), in order to improve the differential diagnosis between ADHD and PD and between the different subtypes of ADHD. Method: The sample…

In this synthesis, we reviewed 65 studies involving elementary students (i.e., grades 1-5) identified with mathematics difficulty (MD) in which authors implemented a mathematics intervention. Of these studies, we identified 33 group designs, 9 quasi-experimental designs, and 23 single-case designs. We aimed to synthesize performance differences…

Learning disabilities are conditions that are associated with difficulties in knowledge and skill acquisition to the level expected of same-age peers. The current book is an international examination of assessment methods, preventative measures, intervention, and research with those individuals with learning disabilities obtained from authors in…

This study of institutional categorization reports an investigation of the practices, procedures and assumptions of psychiatric staff members when diagnosing ADHD. The main data upon which the study is based consist of transcribed audio recordings of meetings in the psychiatric clinic. Here children referred from primary schools on the suspicion…

Children with Attention-Deficiency/Hyperactive Disorder (ADHD) often have co-existing learning disabilities and developmental weaknesses or delays in some areas including speech (Rief, 2005). Seeing that phonological disorders include articulation errors and other forms of speech disorders, studies pertaining to children with ADHD symptoms who…

In the number to position task, several studies have shown that typically developing children shift from a biased (logarithmic) to an accurate (linear) mapping of symbolic digits onto a spatial position on a line. The initial pattern of overestimation of small numbers and the underestimation of larger numbers is compensated by means of age and…

This study of 182 secondary special education students with emotional and/or behavioral disorders investigated their classification by their school districts, in particular how well they were distinguished and represented by their federal categories. The districts used four classification groups (emotional disturbance, other health impairment…

Using data from the Special Education Elementary Longitudinal Study (SRI International, 2002), this study estimated reading growth trajectories in a nationally representative sample of 3,421 students with disabilities ages 7 to 17 representing 11 federal disability categories. Reading achievement in all disability categories increased with age,…

Every year, under the federal law known as the Individuals with Disabilities Education Act (IDEA), millions of children with disabilities receive special services designed to meet their unique needs. Early intervention services are provided through the state to infants and toddlers with disabilities under three years of age and their families. For…

The purpose of the present study was to investigate the presence of teacher biases with regard to identification of students with learning disabilities (LD). Factors related to teachers' gender, age, and experience, along with children's gender, were investigated. Results suggested that teacher gender is associated with biases with regard to…

Briefly reviews conceptual and operational limitations of classic approaches to classifying learning disabled children. Examines new classification research with learning disabled populations which is investigating alternative classification schemes through systematic and empirical hypothesis-testing paradigms, and sparking renewed interest in…

Reviews evidence concerning Interagency Committee on Learning Disabilities's proposal to include social skills deficits as specific learning disability (LD). Proposes three hypotheses: causal, concomitant, and correlational. Found most support for correlational hypothesis, but proposes fourth, functional relationship hypothesis as most…
