Effect of age on the line bisection test.
The purpose of this study was to investigate the effect of age on the line bisection test. One hundred and eight normal dextrals of various ages performed a line bisection task with each hand. They were divided into three different age groups of 36 individuals. The old age group bisected lines significantly further to the right than did the middle and young age groups. Results on the line bisection test of the middle and the young age group were not different. Our results are discussed with reference to the theory of asymmetrical decline or maturing of the hemispheric functions over age.
