本研究提供了数据的因素结构的韦氏学前和小学智力量表（WPPSI）和性别和文化差异的WPPSI测试成绩之间的5-和6岁的儿童来自中国，日本和美国。结果表明，在所有三个国家的语言和非语言因素结构的存在。性别差异的10个子测试一般是一致的，男性优势的子测试的空间能力（迷宫）。中国样本中的男性获得了显着更高的全量表智商分数比女性，并有较低的变异性，在他们的测试成绩。日本和美国的样本中没有这些观察结果。中国样本的平均全量表智商得分为104.1，从1988年到2004年增加了4分。
This study presents data on the factor structure of the Wechsler Preschool and Primary Scale of Intelligence (WPPSI) and sex and cultural differences in WPPSI test scores among 5- and 6-year-olds from China, Japan, and the United States. Results show the presence of a verbal and nonverbal factor structure across all three countries. Sex differences on the 10 subtests were generally consistent, with a male advantage on a subtest of spatial abilities (Mazes). Males in the Chinese sample obtained significantly higher Full Scale IQ scores than females and had lower variability in their test scores. These observations were not present in the Japan and United States samples. Mean Full Scale IQ score in the Chinese sample was 104.1, representing a 4-point increase from 1988 to 2004.
