临床研究发现，右大脑半球的病变会破坏面部知觉。关于健康成年人的面部歧视的决定因素，我们知道的要少得多，尽管许多认知能力的年龄相关差异已被证明与简单的处理速度和局部脑容量的变化有关。在这项研究中，174名年龄在20岁至92岁之间的健康成年人被要求匹配不熟悉面孔的照片。在对他们的表现进行年龄，性别，教育和感知比较速度回归后，增加额叶体积，非额叶体积和来自磁共振成像的脑室-脑比（VBR）的术语改善了模型，并解释了35%的面部识别方差。VBR和处理速度单独占近34%的方差。这些发现表明，正常萎缩的大脑变化和加工速度的下降有助于面部辨别的个体差异。
Clinical investigations have found that lesions of the right cerebral hemisphere can disrupt face perception. Much less is known about the determinants of facial discrimination in healthy adults, although age-related differences in many cognitive abilities have been shown to correlate with simple processing speed and variation in regional brain volumes. In this study, 174 healthy adults between the ages of 20 and 92 were asked to match pictures of unfamiliar faces. After their performance was regressed on age, sex, education, and perceptual comparison speed, adding terms for frontal lobe volume, nonfrontal volume, and ventricle-to-brain ratio (VBR) derived from magnetic resonance imaging improved the model and accounted for 35% of the variance in facial discrimination. VBR and processing speed alone accounted for nearly 34% of the variance. These findings suggest that both normal atrophic brain changes and decreases in processing speed contribute to individual differences in facial discrimination.
