一些研究发现，与来自大家乡的人相比，来自小家乡的人的面部识别能力下降。我们通过将面部识别能力的六项指标与家乡密度联系起来来进一步研究这一问题。我们预测，三个人脸识别能力的措施，其中包括一个学习组件将涉及到家乡的密度，而三个措施，不包括这样的学习组件不会。相反，我们发现这六项指标都与家乡密度无关。有趣的是，我们发现性别和家乡人口密度之间的相互作用在许多这些措施和面部识别的一般指数，与女性从小家乡优于男性，但没有这样的差异在大家乡组。在对先前研究的后续重新分析中，我们发现两种面部识别能力测量中的一种存在类似的相互作用。总之，这些结果揭示了一种由家乡人口密度调制的性别差异模式。如果一个人在家乡的面孔经验确实会影响面孔识别能力，那么要理解这些影响可能需要的不仅仅是对环境的量化。在同一环境中长大的男性和女性可能有不同的经历，这可能会调节对视觉能力的影响。
Several studies have found that individuals from small hometowns show diminished face recognition ability as compared with individuals from larger hometowns. We further this line of research by relating six measures of face recognition ability to hometown density. We predicted that the three face recognition ability measures which included a learning component would relate to hometown density whereas the three measures which did not include such a learning component would not. Instead, we found that none of the six measures related to hometown density. Interestingly, we found interactions between gender and hometown population density on many of these measures and on a general index of face recognition, with females from small hometowns outperforming males from small hometowns but no such differences in the large hometown group. In a follow-up re-analysis of a previous study, we found a similar interaction in one of two face recognition ability measures. Together, these results reveal a pattern of gender differences modulated by hometown population density. If indeed experience with faces in one’s hometown influences face recognition ability, understanding these effects may require more than a quantification of the environment. Men and women growing up in the same environment likely have different experiences, which likely modulates effects on visual abilities.
