We asked whether homosexual and heterosexual men and women differ on standard measures of cognitive ability. Subjects were adults recruited for a family study of sexual orientation. They completed the Fy Scale of the California Psychological Inventory, a self-administered measure of psychological "femininity," and were given subtests of the Wechsler Adult Intelligence Scale and the Primary Mental Abilities test which had been previously shown to discriminate between the sexes. We predicted that homosexual subjects would score significantly in the gender-atypical direction on the Fy scale. We also predicted that they would achieve scores on the tests of cognitive abilities significantly in the direction of the other gender. Comparisons were made between homosexual and heterosexual individuals within gender. Also, comparisons were made between heterosexual men and women to see if our results replicate differences typically found between the genders. As predicted, both homosexual men and women were strongly gender-atypical on the Fy scale relative to their heterosexual counterparts. However, neither differed from heterosexuals on any of the measures of cognitive abilities. Heterosexual men did better than women on the Primary Mental Abilities spatial relations test. We conclude that sexual orientation is not related to specific cognitive abilities.
我们探讨了同性恋和异性恋男性及女性在认知能力标准测量方面是否存在差异。研究对象是为一项性取向家庭研究招募的成年人。他们完成了加利福尼亚心理调查表的Fy量表（一种自我施测的心理“女性化”测量工具），并接受了韦氏成人智力量表和初级心理能力测试的子测验，先前研究表明这些测验能够区分性别。我们预测同性恋受试者在Fy量表上的得分会显著偏向非典型性别方向。我们还预测他们在认知能力测试中的得分会显著偏向另一性别的方向。我们在性别内部对同性恋和异性恋个体进行了比较。此外，我们还对异性恋男性和女性进行了比较，以查看我们的结果是否重现了通常在性别之间发现的差异。正如预测的那样，相对于异性恋同龄人，同性恋男性和女性在Fy量表上都强烈偏向非典型性别。然而，在任何认知能力测量指标上，他们与异性恋者均无差异。在初级心理能力空间关系测试中，异性恋男性比女性表现更好。我们得出结论，性取向与特定认知能力无关。
