The influence of age, sex, and socio-economic status on the performance of normal adults on the Luria-Nebraska Neuropsychological Battery (LNNB)

Abstract

The study was planned to investigate issues relating to the Luria-Nebraska Neuropsychological Battery. The aims were to investigate the influence of age, sex and socio-economic status on performance on the Luria-Nebraska Neuropsychological Battery. A sample of forty males and forty females, stratified according to age (25-40 year olds and 50-60 year olds) and socio-economic status was selected. The results suggested that age formed a significant effect on the total and individual scale scores of the battery. There were no significant sex differences on the total score and most of the scale scores of the battery. Sex formed a significant variable on the performance on the intellectual processes and visual scales. A significant negative correlation was found between total and scale scores of the Luria-Nebraska Neuropsychological Battery and socio-economic status. The implications of these findings are discussed.
