Abstract Fifty‐six children, aged 8 to 13, were divided into three groups based on the degree and direction of their WISC‐R VIQ‐PIQ discrepancies. Group 1 was composed of 13 males and 6 females whose PIQ exceeded their VIQ by at least 12 points (V < P); Group 2 was made up of 12 males and 6 females with VIQs that exceeded their PIQs by 12 or more points (P < V); Group 3 was comprised of 9 males and 10 females whose V‐P differences failed to exceed 8 points in either direction (P=V). The performance of these children on the 11 subscales of the Luria‐Nebraska Neuropsychological Battery‐Children's Revision was compared. Univariate F ‐tests revealed significant differences among the groups on the Receptive Speech, p <.01, and Expressive Language subscales, p< .001. Further analyses that utilized two‐tailed t ‐tests found the V < P group to perform significantly less well than the P = V group on the Receptive Speech and Expressive Language scales. The V < P group was also significantly worse than the P < V group on the Expressive Language scale. These results suggest a possible differential sensitivity of the children's Luria‐Nebraska to verbal and nonverbal cognitive deficits.
