The main purpose of this research was to investigate empirically the Wechsler Intelligence Scale for Children -- the third Jordanian version (hereinafter WISC-III-Jordan) profiles to analyze cognitive factors for 'twice-exceptional' (2E) children characterizing 'mathematical giftedness with learning disabilities (MG/LDs). The paper examined…

Handwriting deficits, or dysgraphia, are present in several neurodevelopmental disorders. To investigate whether dysgraphia differs according to the associated disorder, we performed a detailed analysis of handwriting in a group of French children with developmental coordination disorders (DCD), reading disorder (RD), or comorbid RD and DCD.…

We compared the Wechsler scores of individuals with twice-exceptionality (2e) and giftedness using a three-level Bayesian meta-analysis. Ninety-five effect sizes were calculated from 15 studies (n = 2,106). Results show that individuals with 2e who have learning disabilities perform lower than individuals with giftedness in Full-Scale Intelligence…

It is important to identify cognitive and achievement characteristics that differentiate students who are twice exceptional because they are gifted and have a learning disability (2e-LD) from gifted and average ability peers because this information informs empirically-based identification and support systems for this population. In this study, I…

This study examined the identification frameworks, specific models, and assessment practices used by school psychologists to identify students with specific learning disabilities (SLD) in public schools in the United States. We surveyed school psychologist practitioners using an online survey, conducted a review of state regulations addressing…

Students with specific learning disabilities (SLDs) represent a large proportion of those receiving special education services in U.S. schools, but the relationship between student-level variables and SLD identification is still not well understood. The purpose of this study was to examine the extent to which data collected as part of a…

Within the Canadian context, the two major learning disability classification systems are arguably the American Psychiatric Association's (APA) "Diagnostic and Statistical Manual of Mental Disorders" and the Learning Disabilities Association (LDAC) of Canada's "Official Definition of Learning Disabilities." Several of the more…

The heterogeneity among children with learning disabilities still represents a barrier and a challenge in their conceptualization. Although a dimensional approach has been gaining support, the categorical approach is still the most adopted, as in the recent fifth edition of the "Diagnostic and Statistical Manual of Mental Disorders." The…

The purpose of this article is to understand the decision-making processes by assessment personnel when choosing instruments to evaluate students with learning disabilities. Eight school personnel responsible for the evaluation of students in Texas participated in face-to-face, semistructured interviews. The instruments chosen were based on a…

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…

The Wechsler Intelligence Test for Children -- Fifth Edition (WISC-V) is a comprehensive intellectual ability assessment for children. The WISC-V was developed over the course of five years by an expert team including doctoral-level scientists and clinicians and an advisory panel, who provided expert advice about intellectual ability testing,…

A relationship between motor and mathematical skills has been shown by previous research. However, the question of whether subtypes can be differentiated within developmental coordination disorder (DCD) and/or mathematical learning disability (MLD) remains unresolved. In a sample of children with and without DCD and/or MLD, a data-driven…

Dyslexia and other learning disabilities are not being properly recognized and treated in our educational system or society at large. Unrecognized and untreated learning disabilities represent a serious social and economic problem, not only to the individual but to society as a whole. For example, antisocial behavior, as seen in prison populations…

Children with math disabilities (MD) represent a heterogeneous group and often display deficits in one or more cognitive domains. Math proficiency requires a number of different cognitive processes, including quantitative knowledge, working memory, processing speed, fluid reasoning, and executive functions. Assessment practices that do not address…

Much has been written about gifted students with learning disabilities, but there have been few large-scale empirical investigations, and the concept has proven controversial. The authors reviewed the available empirical literature on these students, focusing on (a) the criteria by which the students were identified and (b) the students'…
