Performance of healthy adults versus individuals with brain injuries on the supplemental measures of the WAIS-R NI

Abstract

The Wechsler Adult Intelligence Scale-Revised as a Neuropsychological Instrument (WAIS-R NI) provides methods to uniformly interpret atypical responses or response patterns. To date, little research has examined the primary population for which the supplemental measures of the WAIS-R NI were intended. The purpose of the present study was to compare the performance of individuals with brain injuries versus healthy adults on the supplemental measures of the WAIS-R NI. Forty-nine healthy adults and 45 individuals with brain injuries were tested. MANOVA indicated a significant main effect for group membership and the results suggest the WAIS-R NI supplemental measures differentiate individuals with brain injuries from healthy adults.

Symbol Digit and the Quantitative EEG

“…Brain Damage. Mercer et al (1998) found that brain injury affected all supplemental measures on the WAIS-R NI (as a neuropsychological instrument). In particular, strong effects were noted for the scales of Digit Symbol (raw score), Digit Symbol Copy (raw score), Free Recall Digit Symbol, Spatial Span Backward, and Sentence Arrangement.…”
