Luria-Nebraska Neuropsychological Battery performance of brain dysfunctional patients with positive or negative findings on current neurological examination.
Two experiments were conducted to investigate the effects of positive or negative neurological examination results on performance on the Luria-Nebraska Neuropsychological Battery in a sample of 229 patients with a history of proven brain damage. The groups did not differ on demographic variables of age, education, or disorder chronicity. The positive and negative neurological examination groups were highly differentiable. A second study demonstrated additional high subgroup differentiability within the positive and negative neurological examination groups as a function of the degree of cognitive deficit demonstrated on the neuropsychological measure. Implications of the results were discussed.
