A battery of spatial visualization land form percepthn plus some tests of arithmetic, vocabulary and social perception has been administered to 274 pairs of identical and 198 pairs of frabmal twins. To assess the importance of hereditary components in the individual differences observed, the within pair variance for fraternal paim was compared with the within pair vazianw for identical pains by the F ratio test. The results for 123 pairs of identiml twins and 91 pairs of fraternal twins on the spatial task, were classified in terms of the apparent psychological task requirements of the test. It appears that tests requiring three-dimensional manipdadion of drawings demonstrate more frequently a statistically significant hereditary component.
对274对同卵双胞胎和198对异卵双胞胎进行了一系列空间视觉地形感知测试，以及一些算术、词汇和社会感知测试。为了评估观察到的个体差异中遗传成分的重要性，通过F比率检验将异卵双胞胎对的对内方差与同卵双胞胎对的对内方差进行了比较。对123对同卵双胞胎和91对异卵双胞胎在空间任务上的测试结果，根据测试表面的心理任务要求进行了分类。似乎需要对图形进行三维操作的测试更频繁地显示出具有统计学意义的遗传成分。
