This paper provides a rationale for basic research and metatheory development in the field of learning disabilities, outlines the steps and cognitive parameters involved in validating such a metatheory, and discusses integrating the findings of basic research with instructional manipulations and reasons for the poor integration of theory and…

In response to a previous article, the paper finds weaknesses in the mechanistic worldview represented by the emphasis on information processing research in constructing a metatheory for learning disabilities. An alternative--contextualist--world view is proposed which is holistic, social, and developmental providing insight into processes of…

In response to articles concerning the author's earlier paper, the paper responds to criticisms concerning contextualism, the role of metatheory, distinctions between basic and applied research, cognitive components and specificity, the science of learning disabilities, neurological indices, model validation, and the nature of learning…

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…

This article describes a theoretical model of reading disability that integrates research findings in cognitive psychology, reading, and education. The model identifies four patterns of reading disability: (1) nonalphabetic readers, (2) compensatory readers, (3) nonautomatic readers, and (4) readers delayed in the acquisition of word recognition…
