This study compared the performance of 51 gifted Caucasian children on the Stanford Binet LM and the Stanford Binet Fourth Edition (SB4) to determine whether significantly different scores would be obtained. The 33 male and 18 female subjects were from middle and upper-middle class families in a western urban area. Their developmental histories, derived from parents' reports, indicated precocious early development of cognitive linguistic abilities. When composite scores were compared, the mean difference between the two tests was 10 points. The LM intelligence quotient was significantly higher than that for the SB4, and the Kaufman Achievement Test total score showed insignificant differences. Correlations between the LM total and the SB4 area scores were significant. The results suggest that the SB4 can be used as part of a system for identifying gifted children, but the composite score cut-off value may have to be adjusted. Further study of the visual abstract reasoning tests is recommended since this sample of gifted children seemed to function quite differently on them than on the verbal and quantitative reasoning tests. Four data tables are included. (TJH)
