The article reviews and interprets some of the literature that has investigated the relationships between refractive status and reading and between binocular status and reading. The characterization of the visual process is pointed out as a major research problem. (Author)

The review examines evaluations of the efficacy of special education programs for mildly disabled children. The author suggests that serious methodological flaws make our present knowledge in this area very weak and proposes a methodology to address and overcome many of the limitations of previous research.

The article reviews issues regarding the role of attention in reading problems manifested by learning disabled students. Characteristics of attention (including arousal, alertness, vigilance, selective attention, and capacity) are considered. (CL)

The paper reviews the recent research bearing on the single cause/multiple cause controversy in regard to reading disabilities. The inadequacy of the common practice of comparing a group of disabled readers with a control group is noted. (Author/SW)

The author considers reasons for the time delay between research findings and classroom application, examines research on teaching math and spelling to the learning disabled (LD) student, and reviews the status of the controversy over process or modality training for LD students. (CL)

Synthesizes information from a 1995 international symposium on longitudinal research in learning disabilities. Discussion of generic considerations of longitudinal research is followed by examination of issues specific to learning disabilities including definition, attrition, composition of research teams, ethical concerns, data collection, and…

A review of 208 studies of children with learning disabilities (LD) published in 10 major journals between 1988 and 1990 examined the extent to which recommendations concerning research design and reporting made in 1980 and 1984 have been implemented. The review found continuing problems, including imprecise subject descriptions, heterogeneous…

Two methodological problems often arising in dyslexia research are considered. The first problem concerns the validity of experimental measures and the related problem of interpreting null results. The second problem involves the effects of sampling from a disabled population if the disorder under investigation has multiple unknown origins.…

Determining whether stimulant medication improves learning or long-term academic achievement in children with attention deficit-hyperactivity disorder involves consideration of (1) the prescription of higher than optimal doses, and (2) overinclusive treatment involving adverse responders. A study designed to overcome these theoretical deficiencies…
