对人类和非人类动物的研究发现，早期生活中暴露于雄激素可能会影响以后的空间表现。最近的研究表明，第二至第四位数字的比例（2D：4D）可能作为产前雄激素暴露的指标。一些研究发现，2D：4D比率预测成人的空间表现，尽管这种关系的性质是模棱两可的。本研究旨在量化2D：4D比例，空间认知和空间导航之间的关系，使用虚拟莫里斯水任务（vMWT）的样本中的年轻成年男性和女性（N = 140）。结果重复了文献中关于2D：4D比率、vMWT性能和空间认知的性别差异的发现。然而，2D：4D比例与男性或女性的空间认知或空间导航并不一致。结果进行了讨论的框架内的雄激素对空间认知的影响，在何种程度上2D：4D的比例作为早期生活雄激素暴露的标志。
Studies in human and non-human animals have found that early life exposure to androgens may affect later spatial performance. Recent studies have suggested that the ratio of the second to fourth digit (2D:4D) may serve as an index of prenatal androgen exposure. Some studies have found that the 2D:4D ratio predicts adult spatial performance, although the nature of the relationship is equivocal. This study was designed to quantify the relationships between 2D:4D ratio, spatial cognition, and spatial navigation using a virtual Morris water task (vMWT) in a sample of young adult men and women (N = 140). The results replicated findings from the literature regarding sex differences in 2D:4D ratio, vMWT performance, and spatial cognition. However, 2D:4D ratio was not consistently related to spatial cognition or spatial navigation in men or women. Results were discussed within the framework of androgen influences on spatial cognition and the degree to which 2D:4D ratio serves as a marker for early life androgen exposure.
