The application of an information processing model for diagnosing and remediating learning disabled children is the focus of much debate. Although this approach is widely practiced in classrooms, advocated by many leaders in the field, and included in federal definitions, the empirical literature is not supportive, and many researchers are ready to dismiss its validity. One of the problems associated with this approach is the assessment instruments. This article reviews both sides of this controversy and suggests the use of the Slingerland Screening Tests as an alternative diagnostic tool for examining information processing skills. A brief overview of this test is presented as well as a discussion of advantages and purposes relevant to the information processing approach. Implications for subsequent research are suggested.T he information processing, model for determining appropriate instructional methods and materials for learning disabled children is currently under serious scrutiny. This model has provided a foundation for the diagnosis, planning, and instruction implementation for many years in the learning disabilities field. The components of this model have been given a variety of labels including "perceptual skills," "learning modalities," "learning styles," and "information processing skills." The focus, regardless of terminology, is on methods of learning-including input or receiving information, integration, and output or expression. The popular theories suggest that an individual's strengths and weaknesses in these skills must be determined through various diagnostic procedures in order to plan and implement appropriate instructional strategies and remedial techniques. For example, a visual learner should be provided instruction with a visual emphasis (i.e., sight word approach.to reading). An auditory learner, on the other hand, would benefit from an auditory approach such as phonics.A conflict, however, exists between research and the learning disabilities theories and educational procedures advocated by some authorities. Empirical evidence does not support differential instruction based on preferred learning styles, and yet this approach is still practiced widely in the schools, discussed in major texts, and emphasized in teachertraining programs. It appears that this model has a strong intuitive value for practitioners in spite of the empirical literature's criticism.Further acceptance of this theory in practice can be seen in the terminology of federal and, in some cases, state definitions and guidelines concerning LD children. The current federal regulations describe learning disabilities in terms of psychological processing disorders. Several states also have incorporated this focus into their definitions. Still, the diagnostic and remedial methods used to operationalize these descriptions have been strongly criticized (Torgesen 1979) so that further research is needed to substantiate this approach to diagnosis and instruction.
