图形后遗症通常被认为是短暂的，并在几毫秒内消失。我们用熟悉的面孔测试了面部后遗症，发现持续的影响长达一周。在3个实验中，参与者首先看到扭曲的名人照片，然后在2个选项的强迫选择任务中选择真实的面孔。在与自适应失真相反的方向上发现了真实性后效；这些影响可以推广到同一个人的其他照片，以及在适应过程中没有出现的名人照片。研究结果支持了基于规范的人脸编码的层次理论，并表明人脸适应效应具有表征基础。他们还指出了适应机制运作中的多个时间尺度，从而提供了高水平适应与神经认知可塑性更一般方面（即学习和记忆）之间的联系。
Figural aftereffects are commonly believed to be transient and to fade away in the course of milliseconds. We tested face aftereffects using familiar faces and found sustained effects lasting up to 1 week. In 3 experiments, participants were first exposed to distorted pictures of famous persons and then had to select the veridical face in a 2-alternative forced choice task. Veridicality aftereffects were found in a direction opposite to the adapting distortion; these effects generalized to other pictures of the same individual and also to pictures of celebrities that had not been shown during adaptation. The findings support hierarchical theories of norm-based face coding and suggest that face adaptation effects have a representational basis. They also point toward multiple timescales in the operation of adaptation mechanisms, thereby providing a link between high-level adaptation and more general aspects of neuro-cognitive plasticity, that is, learning and memory.
