熟悉的人的成功识别是社会交往的关键。尽管对熟悉面孔的神经表征进行了广泛的研究，但我们对这些表征如何随着某人变得熟悉而展开知之甚少。在三个EEG实验的人类参与者的性别，我们阐明了如何表征的脸熟悉和身份出现不同的质量熟悉：短暂的知觉曝光（实验1），广泛的媒体熟悉（实验2）和现实生活中的个人熟悉（实验3）。时间分辨表征相似性分析表明，熟悉质量有深刻的影响，面孔熟悉的表征：他们强烈可见后，个人熟悉，媒体熟悉后较弱，知觉熟悉后缺席。在所有的实验中，我们没有发现增强的面孔身份表征，这表明熟悉和身份表征出现独立的面孔熟悉过程中。我们的研究结果强调了广泛的，现实生活中的熟悉的重要性，出现强大的面孔熟悉的表示，约束模型的面孔感知和识别记忆。
The successful recognition of familiar persons is critical for social interactions. Despite extensive research on the neural representations of familiar faces, we know little about how such representations unfold as someone becomes familiar. In three EEG experiments on human participants of both sexes, we elucidated how representations of face familiarity and identity emerge from different qualities of familiarization: brief perceptual exposure (Experiment 1), extensive media familiarization (Experiment 2) and real-life personal familiarization (Experiment 3). Time-resolved representational similarity analysis revealed that familiarization quality has a profound impact on representations of face familiarity: they were strongly visible after personal familiarization, weaker after media familiarization, and absent after perceptual familiarization. Across all experiments, we found no enhancement of face identity representation, suggesting that familiarity and identity representations emerge independently during face familiarization. Our results emphasize the importance of extensive, real-life familiarization for the emergence of robust face familiarity representations, constraining models of face perception and recognition memory.
