Abstract

This paper examined the factor structure of the Luria-Nebraska Neuropsychological Battery Scales Intelligence and Pathognomonic. The subjects for the study were 270 patients, including 90 normal patients, 90 psychiatric patients, and 90 neurological patients. A principal factor analysis with communalities on the diagonal and iterated to the most ideal solution was used, followed by rotation to the simplest factor structure. The analysis yielded 4 subfactors for each of the two Luria scales. On the Intelligence scale, factors were general verbal intelligence, arithmetic, a frontal verbal factor, and a right frontal sequencing factor. Analysis of the Pathognomonic scale yielded a simple perceptual/expressive factor, a construction speed factor, a basic visual/spatial factor, and a higher cognitive factor. These results were generally in accord with Luria's theories.
