人类认知和运动技能的性别差异可能部分归因于性激素对大脑的组织或激活作用。在这项研究中，在月经周期的两个阶段，对正常骑自行车的女性进行了广泛的认知和运动测试，以检测任何由激素介导的表现变化。结果证实了在各种快速手动和发音测量以及一些非语言/空间测试中，月经周期的变化。这一结果为这一假设提供了合格的支持，即在周期的黄体期，高水平的性腺类固醇可能有助于有利于女性的技能，但不利于有利于男性的技能。讨论了这些结果对人类性别差异研究的意义。
Sex differences in human cognitive and motor skills may in part be due to organizational or activational effects of sex hormones on the brain. In this study, an extensive battery of cognitive and motor tests was administered to normally cycling women at two phases of the menstrual cycle, in order to detect any hormone-mediated changes in performance. Results confirmed changes across the menstrual cycle on a variety of speeded manual and articulatory measures, and on some nonverbal/spatial tests. The results provide qualified support for the hypothesis that the high levels of gonadal steroids present at the luteal phase of the cycle may facilitate skills favoring females, but be detrimental to skills favoring males. The implications of these results for research in the area of human sex differences are discussed.
