The Identical Blocks Test of spatial ability was administered to subsamples of the two largest ethnic groups tested in the Hawaii Family Study of Cognition--Americans of European ancestry (171 families) and Americans of Japanese ancestry (98 families). Results of a hierarchical multiple regression analysis of family data and correlational analyses provided no evidence to support the hypothesis that spatial ability is influenced by a major, X-linked, recessive gene. Thus it appears that recent failures to replicate the sex-linkage pattern obtained by Stafford (1961) are not due to differences in the tests employed. We suggest that alternative explanations should be sought for the well-known sex difference in spatial ability.
在夏威夷认知家庭研究中，对两个最大种族群体的子样本进行了空间能力的相同积木测试，这两个群体分别是欧洲裔美国人（171个家庭）和日裔美国人（98个家庭）。对家庭数据进行的分层多元回归分析和相关分析结果，没有提供证据支持空间能力受一个主要的、X连锁隐性基因影响这一假设。因此，最近未能复制斯塔福德（1961年）获得的性连锁模式，似乎并非由于所采用测试的差异。我们建议，对于空间能力中众所周知的性别差异，应寻求其他解释。
