The regression-based discrepancy definition of learning disabilities has been suggested by Rutter and Yule as an improvement of the well-known and much criticized achievement-intelligence discrepancy definition, whereby the examinee's predicted reading attainment is substituted for the intelligence score in the discrepancy expression. Even though…

Learning disabilities is presented as a construct supported by psychoeducational, socioemotional, and physiological data, as illustrated by the M. Meeker paradigm. (Author)

The authors assert that progress in conceptualizing learning disabilities and related intervention procedures is dependent on systematic, consistent, and educationally grounded theory, and that each practitioner should adopt a system and use it consistently. A cognitive-field model is illustrated and its use as a foundation for educating LD…

The article deals with the problem of scientific definitions, focusing on its application to learning disabilities. (DLS)

The paper develops the phonological-core variable difference model to conceptualize differences between dyslexic and other poor readers. The model highlights the importance of viewing the concept of dyslexia as the outcome of the application of an arbitrary criterion in a continuous distribution. (Author/DB)

This article examines the research surrounding definitions and selection criteria for learning disabilities and attention deficit/hyperactivity disorder at the postsecondary level. Implications from and for the courts follow a critical analysis of the professional literature. The need for theory-based models to investigate relationships between…

Data from the Connecticut Longitudinal Study were used to compare two definitions of reading disability: a discrepancy-based model and a low reading achievement model. Children (n=415) satisfying each definition in second grade were compared retrospectively in kindergarten and prospectively in fifth guide. Findings suggest more similarities than…
