David Wechsler played a signal role in the history of intelligence with the construction of the Wechsler Adult Intelligence Scales and the Wechsler Intelligence Scale for Children. The original WISC was published in 1947 and is the most widely used children's intelligence test in the world. The WISC-III was standardized in the United States in 1991. The WISC-III represents not only a further revision of its items, but also a four scale index score structure that assesses Verbal Comprehension, Perceptual Organization, Attention or Working Memory, and Processing Speed., as well as the traditional IQ scores. The recent adaptation and standardization of the WISC-III in many countries throughout the world provides an opportunity for its cross-cultural analysis. One question concerns the degree to which verbal and non-verbal items change from culture to culture, and which items are common across cultures. A related question concerns the degree to which the norms for the subtests, for the Verbal IQ, Performance IQ, and Full Scale IQ vary from culture to culture. To what degree do the reliabilities of the subtests and IQ scores vary? A further question is related to the factor structure across cultures, which raises issues regarding psychometric characteristics of the WISC-III but also, possible differences in specific cognitive processes due to the effects of cultural factors. These issues have implications for cross-cultural psychometric properties of the WISC-III, and also for intelligence theory, cross-cultural universals and cultural specifics in intelligence.
