Simultaneous and successive processing dimensions of the Halstead-Reitan Neuropsychological Battery

Abstract

This study examined the neuropsychological elements involved in simultaneous and successive processing for learning disabled children. A step-wise multiple regression suggested that successive processing played a direct role in those HRNB tests seen to measure mental flexibility, verbal and non-verbal auditory discrimination, and psychomotor speed. Further analysis indicated tactual discrimination/kinesthesis, localization of spatial elements, non-verbal concept formation, and non-verbal intermediate memory as neuropsychological functions requiring simultaneous processing. The results were interpreted as lending support to the neuropsychological differences between subtests of the WISC-R grouped on the basis of successive and simultaneous processing demands.
