Regressions of offspring on midparent value for tests of specific cognitive abilities in Korea were considerably higher than those for Americans of Japanese ancestry or Americans of European ancestry tested in Hawaii. This greater parent-offspring resemblance in Korea may be due to the particular method of test administration or to an increased genetic variance resulting from assortative mating. The pattern of parent-child correlations for three relatively pure tests of spatial ability and for the spatial factor did not conform to that of a sex-linked recessive character.
在韩国，对特定认知能力测试的后代与中亲值的回归系数显著高于在夏威夷测试的日裔美国人或欧裔美国人。韩国这种更强的亲子相似性可能归因于特定的测试管理方法，或者是选型交配导致的遗传方差增加。三项相对纯粹的空间能力测试以及空间因素的亲子相关模式并不符合性连锁隐性性状的模式。
