我们使用高层次的视觉后效引起的适应现实的面孔，调查复杂的模式感知的视觉表征。我们发现，暴露在一个人的脸几秒钟产生了显着的和精确的偏见，在随后的看法的脸身份。在计算得出的“面部空间”的上下文中，适应具体地沿着穿过适应和平均面部的轨迹沿着改变感知，选择性地促进对位于该轨迹上的测试面部的识别，并损害对其他面部的识别。结果表明，编码的面孔和其他复杂的模式借鉴对比神经机制，参考的刺激类别的集中趋势。
We used high-level configural aftereffects induced by adaptation to realistic faces to investigate visual representations underlying complex pattern perception. We found that exposure to an individual face for a few seconds generated a significant and precise bias in the subsequent perception of face identity. In the context of a computationally derived 'face space,' adaptation specifically shifted perception along a trajectory passing through the adapting and average faces, selectively facilitating recognition of a test face lying on this trajectory and impairing recognition of other faces. The results suggest that the encoding of faces and other complex patterns draws upon contrastive neural mechanisms that reference the central tendency of the stimulus category.
