在不同领域的特定认知能力通常被发现是高度遗传的，并且与一般认知能力(g)在表型和遗传上都有很大的相关性。最近的双胞胎研究发现，记忆和识别面孔的能力是一个例外，这种能力同样是可遗传的，但在表型上与g和一般物体识别基本无关。然而，面部识别和其他能力之间的遗传关系（它们共享共同遗传病因的程度）不能从表型关联中确定。在这项研究中，据我们所知，首次研究了面部识别与其他领域之间的遗传关联，2000名18岁和19岁的英国双胞胎完成了测试，评估了他们的面部识别、物体识别和一般认知能力。结果证实了人脸识别的遗传性（61%），多变量遗传分析发现，大多数这种遗传影响是独特的，与其他认知能力无关。
Specific cognitive abilities in diverse domains are typically found to be highly heritable and substantially correlated with general cognitive ability (g), both phenotypically and genetically. Recent twin studies have found the ability to memorize and recognize faces to be an exception, being similarly heritable but phenotypically substantially uncorrelated both with g and with general object recognition. However, the genetic relationships between face recognition and other abilities (the extent to which they share a common genetic etiology) cannot be determined from phenotypic associations. In this, to our knowledge, first study of the genetic associations between face recognition and other domains, 2,000 18- and 19-year-old United Kingdom twins completed tests assessing their face recognition, object recognition, and general cognitive abilities. Results confirmed the substantial heritability of face recognition (61%), and multivariate genetic analyses found that most of this genetic influence is unique and not shared with other cognitive abilities.
