This study was conducted to pursue the improvement for discriminant power of Benton Neuropsychological Assessment(BNA) by taking advantages of qualitative analysis of BNA performances. Subjects were 73 patients with unilateral brain injury, 122 controls(91 normal adults and 31 psychiatric patients) and 47 malingerers. With some qualitative variables applied in this study, the percent of grouped cases correctly classified was 88.75%. This figure was 7.5% higher than diagnostic hit ratio by using Benton's suggestion. This results verified the superiority of the qualitative approach in this study. The contents of the discriminant variables involved in discriminant functions, which discriminate patients with left or right hemisphere lesions from controls and malingerers, were also examined. Finally, the limitations of this study and suggestions for following studies were discussed.
