Research on neurodevelopmental disorders (NDDs) has led us to refine our theoretical and methodological approaches. We explore whether new deficit clusters in line with the Research Domain Criteria, a novel multifactorial framework, optimally explain known conditions such as ADHD, DLD, or SLD in reading. Following the PRISMA guidelines for…

Types of mathematical learning disability (MLD) are very heterogeneous. Lower scores on mathematics and several cognitive skills have been revealed in samples with MLD compared with those with typical development (TD), but these studies vary in sample selection, making it difficult to generalize conclusions. Furthermore, many studies have…

Developmental dyscalculia (DD) affects 2-6% of the population. Yet, a readily accessible list of potential interventions for DD is not available or can be easily found by educators. With a large percentage of the population afflicted with DD, educators should be made aware of what supportive approaches are available. The purpose of this study was…

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…

Children with learning difficulties suffer from working memory (WM) deficits. Yet the specificity of deficits associated with different types of learning difficulties remains unclear. Further research can contribute to our understanding of the nature of WM and the relationship between it and learning difficulties. The current meta-analysis…

The purpose of this study was to synthesize the findings from 23 articles that compared the mathematical and cognitive performances of students with mathematics learning disabilities (LD) to (a) students with LD in mathematics and reading, (b) age- or grade-matched students with no LD, and (c) mathematical-ability-matched younger students with no…

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 authors emphasize the need for developing educational interventions that encourage generalization in learning disabled students from one set of responses to another. (CL)

A study synthesized findings of 41 studies that compared children with and without learning disabilities in reading on immediate-memory performance. Results indicate children with learning disabilities were distinctly disadvantaged compared to average readers when memory manipulations required the naming of visual information and task conditions…

Short-term memory deficits are examined as precursors of learning disabilities in early childhood. The theories of Jean Piaget, Robbie Case, and Joseph Torgesen are reviewed to construct a theoretical framework. Supportive experimental studies are described, followed by implications for remediation and intervention. (Author/JDD)

Major research findings relevant to use of the Wechsler Digit Span subtest in psychoeducational assessment are summarized. The cognitive processes and behavioral characteristics which determine performance on Digit Span are related to complex abilities. Recommendations and implications for research and assessment practice are presented.…

The purpose of this paper was to track the history of learning disabilities and collect intervention theories which might be helpful for adult college students suffering from any number of learning disabilities (LD). There is a vast difference between a learning difficulty and a learning disability; an individual with learning difficulty can learn…

Although cognitive psychology is concerned with the processes of knowing rather than with behavior, certain applications of cognitive psychology and learning theory have been achieved: (1) behavior modification; (2) bio-feedback; (3) psycholinguistics; and (4) information processing psychology.

Research evidence is reviewed to show that transcription and working memory processes constrain the development of composition skills in students with and without learning disabilities and that in turn other processes constrain the development of transcription and working memory skills. Interventions for transcription are discussed. (Author/CR)
