This review documents the learning disabilities (LD) identification criteria and procedures utilized in empirical research including students with LD published from 2001 to 2013 in three journals dedicated to the study of LD. Results reveal several troublesome findings related to transparency in reporting and the coherence of the LD construct.…

Because of the Flynn effect, IQ scores rise as a test norm ages but drop on the introduction of a newly revised test norm. The purpose of the current study was to determine the impact of the Flynn effect on learning disability (LD) diagnoses, the most prevalent special education diagnosis in the United States. Using a longitudinal sample of 875…

Replies to criticism of work at Minnesota Institute for learning disabilities. Suggests that the work (what is known) in LD reflects the state of practice (what is done). Suggests the LD population is not clearly defined, and research does not indicate that LD children require interventions unique to their category. (Author/CL)

Compares two meta-analyses of instructional interventions for students with learning disabilities conducted by Gersten and Baker, and Swanson, focusing on issues of grouping and reporting such studies and of treating differing outcome measures. Considers the identification of important instructional components in both meta-analyses. (JPB)

This study provides support for a potential subclinical marker in the executive function domain of siblings (n=18, ages 8-18) of autistic individuals, compared to learning-disabled controls. No group differences in theory-of-mind abilities were found. The need to develop more sensitive measures is discussed. (Author/JDD)

A study of 22 learning disabled (LD) and normal children (mean age nine years) was undertaken to illustrate the research problems involved in using analysis of covariance to control for differences between LD and normal children on measures of intelligence. (SW)

The conclusion that learning disabled children have a deficit in perceptual organization is not accepted because of two major methodological problems. Dean refutes this criticism showing that learning disabled children have a perceptual organization deficit when compared with emotionally disturbed children. (Author/BEF)

The paper evaluates the empirical and theoretical basis upon which several recent studies reject the hypothesis of a visual-perceptual deficit in reading disabilities. (Author)

The authors surveyed experts in the field of neuro-behavioral research to determine the directions of progress being made in increasing understanding of neural processing and storage of information. Based on this investigation, their report presents examples of research being pursued in this area. The authors see neuro-behavioral research leading…

Analysis of 85 journal articles and 36 doctoral theses disseminated in Canada revealed that the functionalist definition of learning disability and the assumption of specific etiology remain fixed in Canadian special education research. This finding suggests the need to introduce an ecological perspective in future studies of learning disability.…

A review of 913 studies involving students with learning disabilities found treatment outcomes were significantly affected by the following violations: teacher effects, establishing criterion levels of instructional performance, reliance on experimental measures, using different pretest and posttest measures, using a sample heterogeneous in age,…

This paper examines studies of the Minnesota Institute which were interpreted as demonstrating that students with learning disabilities are not distinguishable from other low-achieving students. Results of the reexamination indicate that learning disabilities and low achievement can be clearly differentiated, even in studies indicating that little…

Synthesizes findings from 36 studies that validated the Dunn and Dunn Model of Learning-Style Preferences. Questions are raised regarding the validity of the model, the nature of the literature base, the interpretation of the meta-analytic findings, and the conclusions. The article concludes that the model has not been adequately validated.…

Findings from a review of 22 studies on self-efficacy beliefs of students with learning disabilities (LD) are discussed. Results suggest that in specific contexts (in the writing performance of students with specific writing difficulties, in particular) students appear to optimistically miscalibrate their self-efficacy. Methodological research…

The problem of variability of data, even in presumable homogeneous subgroupings of handicapped children, which contaminates the results of many special education curriculum evaluation studies is examined with a study of 103 second-grade learning disabled students. The distortion of statistics calculated on samples of extreme variability; coupled…
