The study investigated cultural bias in the verbal items of the Wechsler Intelligence Scale for Children-Revised (WISC-R). Six verbal subtests of the WISC-R were administered to 40 Anglo, 40 Mexican-American, and 40 Navajo intermediate grade students matched for grade level, sex, and socioeconomic status. The responses of three groups of subjects to individual items comprising verbal subtests were analyzed by log-linear technique using the likelihood ratio chi-square statistic. The findings revealed that the performance of subjects was homogeneous across three cultural groups on the items comprising Arithmetic, Comprehension, and Digit Span subtests. Ten of the 79 items comprising Information, Similarities, and Vocabulary subtests were, however, found to be biased against Mexican-American subjects whereas 15 items of the same three subtests were identified as biased against Native-American Navajos.
