正常受试者的面部识别取决于形状和表面反射线索的比例大致相等，而物体识别主要取决于形状线索。有可能发育性面容失认症的缺陷并不在于他们识别面孔本身的能力，而在于他们使用反射线索的能力。类似地，超级识别者在面部识别方面的卓越能力可能是由于上级的表面反射感知和记忆。我们测试了这种可能性，管理测试的面孔感知和面部识别，只有形状或反射线索可用于发展prosopagnosics，超级识别器，和控制对象。在所有的测试中，面部识别能力与形状和色素的相对使用无关。更善于使用形状或反射率线索的受试者也更善于使用其他类型的线索。这些结果不支持表面反射感知能力的变化是人脸识别能力变化的根本原因的建议。相反，这些发现支持了这样一种观点，即面部识别能力与使用整合形状和色素信息的表征的神经回路有关。
Face recognition by normal subjects depends in roughly equal proportions on shape and surface reflectance cues, while object recognition depends predominantly on shape cues. It is possible that developmental prosopagnosics are deficient not in their ability to recognize faces per se, but rather in their ability to use reflectance cues. Similarly, super-recognizers’ exceptional ability with face recognition may be a result of superior surface reflectance perception and memory. We tested this possibility by administering tests of face perception and face recognition in which only shape or reflectance cues are available to developmental prosopagnosics, super-recognizers, and control subjects. Face recognition ability and the relative use of shape and pigmentation were unrelated in all the tests. Subjects who were better at using shape or reflectance cues were also better at using the other type of cue. These results do not support the proposal that variation in surface reflectance perception ability is the underlying cause of variation in face recognition ability. Instead, these findings support the idea that face recognition ability is related to neural circuits using representations that integrate shape and pigmentation information.
