识别面部身份的专业知识，特别是对面部特征之间细微差异的敏感性。进入青春期后会有所改善。为了评估经验的影响，我们测试了成年人和8岁的孩子，他们的脸只在面部特征的间距上不同。刺激是成年人，8岁的人和猴子的脸。我们表明，成年人的专业知识是由经验塑造的：他们在看到直立的人脸特征间距差异方面比直立的猴子面孔准确9%。8奥尔兹的儿童对人类和猴子面孔的准确率比成人低14%（实验1），他们对人类面孔的准确率并不比儿童面孔的准确率高（实验2）。研究结果表明，8岁以后人脸识别的改善与人脸经验无关，可能与记忆或感知的一般改善有关（例如，超敏锐度和空间整合）。
Expertise in recognizing facial identity, and, in particular, sensitivity to subtle differences in the spacing among facial features. improves into adolescence. To assess the influence of experience, we tested adults and 8-year-olds with faces differing only in the spacing of facial features. Stimuli were human adult, human 8-year-old, and monkey faces. We show that adults' expertise is shaped by experience: They were 9% more accurate in seeing differences in the spacing of features in upright human faces than in upright monkey faces. Eight-year-olds were 14% less accurate than adults for both human and monkey faces (Experiment 1), and their accuracy for human faces was not higher for children's faces than for adults' faces (Experiment 2). The results indicate that improvements in face recognition after age 8 are not related to experience with human faces and may be related to general improvements in memory or in perception (e.g., hyperacuity and spatial integration).
