Although specific learning disabilities (SLD) represent the largest category for which school-age children receive special education services, the science and practice of SLD identification continues to evade consensus. Our goal is to bring together trainers and researchers with different perspectives on SLD identification to help spur a move…

There has been vigorous debate within the state of California and elsewhere as to what constitutes appropriate procedures for determining whether an individual qualifies for special education and related services under the category of specific learning disability (SLD). Within the professional literature, there is growing support for educational…

The rise in popularity of Response to Intervention (RTI) as a method of identifying Learning Disabilities (LD) is partially due to the psychometric and theoretical issues inherent to the use of IQ tests in the once popular discrepancy method of identification. However, both RTI and discrepancy theories have their shortcomings, and criticisms…

As a result of the upcoming Federal reauthorization of the Individuals With Disabilities Education Improvement Act (IDEA), practitioners and researchers have begun vigorously debating what constitutes evidence-based assessment for the identification of specific learning disability (SLD). This debate has resulted in strong support for a method that…

Learning disabilities (LDs) have long been presumed to be a neurological disorder resulting from a deficit in 1 or more cognitive processes. Although the emphasis on cognitive processing disorders has been included in the definition since the term was coined, and although it arguably represents the key distinguishing characteristic of LDs, it also…

In this article, we provide an overview of current knowledge on the underlying cognitive deficits associated with mathematics learning disabilities (MLD). We highlight difficulties surrounding the identification of MLD that include inconsistency in defining MLD, comorbidity with other disabilities, problems associated with assessment tools and…

The 2004 Individuals with Disabilities Education Improvement Act (IDEA) and subsequent regulations published in 2006 have significantly changed the identification process for students suspected of having specific learning disabilities. Rather than using a discrepancy model contrasting intellectual and achievement test results, assessment…

DSM-5, the fifth edition of the American Psychiatric Association's "Diagnostic and Statistical Manual of Mental Disorders," was published in May 2013, amidst a storm of controversy. This article focuses on changes made to the diagnostic criteria for Specific Learning Disorders (SLD). Primary criticisms of the changes in the SLD concern…

Research has demonstrated that many children have learning problems related to deficits in specific cognitive processes that are not adequately represented by a single IQ score. The administration of cognitive measures that include narrow abilities is useful in understanding specific learning problems and developing effective interventions.…

ADHD is an impairing psychological disorder that predominantly affects children, but also adults to a lesser extent. As a result, a considerable amount of research has been completed in recent years to better understand the nature of the disorder to best treat individuals experiencing symptoms of ADHD. Especially with the publication of the…

This article demonstrates how the broad and narrow abilities and processes that comprise Cattell-Horn-Carroll (CHC) theory and their relations to specific academic outcomes have begun to transform our current understanding of the definition of and methods for identifying specific learning disability (SLD), particularly in the school setting. The…

Theory of mind was assessed in 32 adults with HFA, 29 adults with Asperger syndrome and 32 neurotypical adults. The HFA and Asperger syndrome groups were impaired in performance of the Strange stories test and the Faux-pas test and reported more theory of mind problems than the neurotypical adults. The three groups did not differ in performance of…

The Delis-Kaplan Executive Function System (D-KEFS; Delis, Kaplan, & Kramer, 2001a) is a set of standardized tests for comprehensively assessing higher-level cognitive functions, referred to as "executive functions," in both children and adults (aged 8 to 89). Executive functions draw on the individual's more fundamental or primary cognitive…

Data on the relationships between cognitive and physical phenotypes, and a deficit of fragile X mental retardation 1 (FMR1) gene-specific protein product, FMRP, are presented and discussed in context with earlier findings. The previously unpublished results obtained, using standard procedures of regression and correlations, showed highly…
