The X-linked recessive gene hypothesis, a theory to predict the mode of genetic inheritance of spatial ability, was tested using a new Rasch-calibrated space test, the Three-dimensional Cube Test (Gittler, 1990). This allowed solving the homogeneity problem (insufficient unidimensionality of test material) by which earlier research in this field was affected. The empirical correlations from our sample of 134 families were compared with the theoretically predicted values. Present data do no corroborate the model; however, the problems of its general falsification are discussed. The fact that differences in performance in favour of males exist in the parental generation but not in the filial generation accentuates the importance of environmental factors.
X连锁隐性基因假说，一种预测空间能力遗传模式的理论，使用一种新的经过拉施校准的空间测试——三维立方体测试（吉特勒，1990年）进行了检验。这使得能够解决同质性问题（测试材料的单维性不足），该领域早期研究曾受此问题影响。将我们134个家庭样本的实证相关性与理论预测值进行了比较。目前的数据并未证实该模型；然而，讨论了其被全面证伪的问题。在亲代中存在有利于男性的表现差异，但在子代中不存在这一事实，凸显了环境因素的重要性。
