Performance on the Luria-Nebraska Neuropsychological test Battery-Children's Revision: A comparison of children with and without significant WISC-R VIQ-PIQ discrepancies

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.

Epidemiologic characteristics and sequelae of closed head‐injured children and adolescents: A review

“…Generally, the studies in Table 1 with LD populations, many of which included CHI children, showed the Pathognomonic scale of the LNNB-C to be the best group discriminator (Hale & Foltz, 1982;Teeter, Boliek, Obrzut, & Malsch, 1986) and further demonstrated the LNNB-C subscales to be sensitive to VIQ weaknesses on the WISC-R (Gilger & Geary, 1985). When using the LNNB-C to discriminate brain-damaged children from normal children the Pathognomonic and the Left and Right Sensorimotor scales have been most effective (Sawicki, Leark, Golden, & Karras, 1984).…”

Evidences of validity and reliability of the Luria-Nebraska Test for Children

“…In a study with the original battery for children, Gilger and Geary (1985) detected a good capability of the LNNB-CR to trace neuropsychological deficits in expressive and receptive language functions, which were in accordance with discrepant results between verbal and performance scales in the WISC-R. More recent studies, with another largely used neuropsychological battery, the Halsted-Reitan Neuropsychological Battery, are also grounded on relations between intelligence and neuropsychological functions. A study with children presenting learning disabilities showed distinct result profiles in this battery in children from the various inferior ranges of the WISC-R (Davis et al 2001).…”

Validity of IQ-Achievement Discrepancy Criteria for Identifying Learning Disabilities

“…The current study tested the validity of the WISC-R distinction specifically for LD children presenting with the LV-HP WISC IQ profile that has been reported to account for the highest frequency of children with LD (Bloom, Topinka, Goulet, Reese, & Podruch, 1986;Galvin, 1981;Gilger & Geary, 1985;Lueger, Albott, Hilgendorf, & Gill, 1985) and may represent the greatest overlap with the SL profile in terms of its implications for functioning. In the Fletcher et al (1992) study both_the WISC Full Scale (FS) and PIQ means of their low achieving group were in the average range rather than loiv average and therefore were not strictly representative of an SL level of functioning.…”
