Further Evidence on the Cognitive Abilities of the Japanese: Data from the WPPSI

Abstract
The structure of abilities of Japanese children is analysed in terms of the Burt-Vernon hierarchical model of intelligence. The data are derived from the Japanese standardisation of the Wechsler Preschool and Primary Scale for Intelligence. It is found that Japanese children do not differ significantly from white American children on Spearman's g, are significantly inferior on the group verbal factor and superior on the group perceptual factor. On the primary abilities, Japanese children are inferior on verbal comprehension, not significantly different on perceptual speed, and superior on number and spatial ability. It is suggested-that this pattern of Japanese cognitive strengths and weaknesses helps to clarify a number of conflicting findings on Japanese intelligence.
