大量的行为学证据表明，我们对面孔的内部表征或面孔原型可以通过即时经验动态更新。这是由强大的吸引力后效应现象，即原来没有吸引力的面孔变得有吸引力后，我们暴露在一组没有吸引力的面孔。虽然行为学证据表明这种效应有很强的神经基础，但神经影像学证据有限。在这里，我们使用功能近红外光谱方法（fNIRS）来弥合这一差距。在预适应试验中，参与者判断三组面孔的吸引力：正常/未扭曲的面孔，压缩面孔（内部特征和它们之间的距离被压缩）和扩展面孔（内部特征和它们之间的距离被拉伸）。然后，参与者被展示了5分钟的极度压缩的面孔作为适应刺激，之后参与者在适应后试验中判断了相同的三组面孔。在行为上，适应试验后，参与者认为压缩的面孔更具吸引力，而他们认为其他两组面孔不那么有吸引力，复制了强大的适应效应。fNIRS结果表明，短期暴露于压缩的脸导致神经活动的显着下降，所有的脸类型，但在一个更广泛的网络，在额叶和枕叶皮层的未扭曲的脸。综上所述，这些研究结果表明，面部吸引力后效应主要反映了面部原型的神经表征的变化，以响应最近暴露于新的面部样本。
Extensive behavioral evidence shows that our internal representation of faces, or face prototype, can be dynamically updated by immediate experience. This is illustrated by the robust attractiveness aftereffect phenomenon whereby originally unattractive faces become attractive after we are exposed to a set of unattractive faces. Although behavioral evidence suggests this effect to have a strong neural basis, limited neuroimaging evidence exists. Here we used functional near-infrared spectroscopy methodology (fNIRS) to bridge this gap. During the pre-adaptation trials, participants judged the attractiveness of three sets of faces: normal/undistorted faces, compressed faces (the internal features and distances between them were compressed), and expanded faces (the internal features and distances between them were stretched). Then, participants were shown extremely compressed faces for 5 minutes as adaptation stimuli, after which participants judged the same three sets of faces in post-adaptation trials. Behaviorally, after the adaptation trials, participants rated the compressed faces more attractive whereas they judged the other two sets of faces as less attractive, replicating the robust adaptation effect. fNIRS results showed that short-term exposure to compressed faces led to significant decreases in neural activity to all face types, but in a more extended network of cortical regions in the frontal and occipital cortexes for undistorted faces. Taken together, these findings suggest that the face attractiveness aftereffect mainly reflects changes in the neural representation of the face prototype in response to recent exposures to new face exemplars.
