Item Interpretation of the Luria-Nebraska Neuropsychological Battery

Book excerpt: The Luria-Nebraska Neuropsychological Battery is a relatively new neurodiagnostic test, and there is a growing demand for material on the more advanced aspects of its interpretation. This book, organized around the theoretical meaning of items, the empirical correlations between items, and the factor structure of the individual scales, is a first response to that demand. It will serve to give greater understanding of the psychological skills that underlie each item on the Luria-Nebraska battery—an understanding prerequisite to the techniques of “syndrome analysis” described in the writings of A. R. Luria—and it will be particularly useful to those who have limited experience with actual case material. The major part of the book is an analysis of each Luria-Nebraska scale, either item by item or as a unit. For each scale the authors examine the theoretical intent of the items and the underlying skills according to Luria’s theory. They then present the results of item interrelations analysis to determine whether the items tap common skills. Finally they describe the factor structure of the various scales, exploring the interrelations of items within each scale. In addition to analyzing the behavioral scales of the Luria-Nebraska battery, the book reviews a number of other empirical scales that further aid interpretation—particularly the experimental localization scales that tap focal deficits in specific areas of the brain. Also included are case histories that illustrate the process of diagnosis in patients who receive a series of Luria-Nebraska batteries over the course of their treatment. Finally, the authors briefly discuss subcortical disorders—an issue often ignored in clinical neuropsychological testing.
