Concurrent validity and analysis of learning curves on the memory scales of the Luria-Nebraska Neuropsychological Battery-Third Edition.
The purpose of this investigation was to evaluate the concurrent validity of the Luria-Nebraska Neuropsychological Battery-Third Edition (LNNB-III) memory scales with the WSM-R (study 1), as well as to investigate performance differences between brain-injured and nonbrain injured subjects on the LNNB-III memory indices, first trial learning, and learning curves of each scale (study 2). Study 1 had 90 subjects (46 males and 44 females). Study 2 had 228 subjects (109 normals and 119 brain-injured). Significant correlations were found between the LNNB-III memory scales and the WSM-R index scores. Findings also revealed poorer overall performance and initial learning of brain-injured subjects across all LNNB-III memory scales. Brain-injured subjects also demonstrated significantly reduced learning curves across repeated trials on two of the three scales. The clinical implications of these findings are discussed.
