与不熟悉的面孔相比，熟悉的面孔的识别是鲁棒的，并且能够抵抗显著的图像失真或退化。在这里，我们测试了熟悉的面孔识别的灵活性与变形范例，其中一个人熟悉的面孔的外观与一个陌生人的外观（实验1）和自己的脸的外观与熟悉的面孔的外观和一个陌生人的外观（实验2）混合。这两个实验的目的是评估如何识别身份的类别边界的影响熟悉。我们发现一个狭窄的分类边界的身份熟悉的面孔时，他们与不熟悉的身份相比，控制条件，其中出现的两个不熟悉的面孔是混合的。我们的研究结果表明，熟悉扭曲的表征几何的脸空间，放大知觉距离的小变化，熟悉的面孔，是不一致的结构特征，定义他们的身份。
Recognition of familiar as compared to unfamiliar faces is robust and resistant to marked image distortion or degradation. Here we tested the flexibility of familiar face recognition with a morphing paradigm where the appearance of a personally familiar face was mixed with the appearance of a stranger (Experiment 1) and the appearance of one's own face with the appearance of a familiar face and the appearance of a stranger (Experiment 2). The aim of the two experiments was to assess how categorical boundaries for recognition of identity are affected by familiarity. We found a narrower categorical boundary for the identity of personally familiar faces when they were mixed with unfamiliar identities as compared to the control condition, in which the appearance of two unfamiliar faces was mixed. Our results suggest that familiarity warps the representational geometry of face space, amplifying perceptual distances for small changes in the appearance of familiar faces that are inconsistent with the structural features that define their identities.
