长期以来，感觉适应和视觉后效一直让我们深入了解视觉感知基本维度的神经代码。最近发现的复杂形状（如人脸）的感知适应效应可以为高级视觉表征提供类似的见解。在这里报告的实验中，我们首先证明了，面对适应转移跨越了实质性的变化，在观点和这种转移发生通过过程不太可能是特定的面孔。接下来，我们使用在反射率或形状上选择性变化的面部变形来探索面部识别的视觉代码。这些变形的适应影响的看法“相反”的面孔都从同一个观点，并从不同的观点。这些结果是一致的高层次的脸表示，池的局部形状和反射模式到配置，指定面部外观在一个范围内的三维视点。这些发现对人脸识别的计算模型以及人脸和物体识别的竞争神经理论都有影响。
Sensory adaptation and visual aftereffects have long given insight into the neural codes underlying basic dimensions of visual perception. Recently discovered perceptual adaptation effects for complex shapes like faces can offer similar insight into high-level visual representations. In the experiments reported here, we demonstrated first that face adaptation transfers across a substantial change in viewpoint and that this transfer occurs via processes unlikely to be specific to faces. Next, we probed the visual codes underlying face recognition using face morphs that varied selectively in reflectance or shape. Adaptation to these morphs affected the perception of "opposite" faces both from the same viewpoint and from a different viewpoint. These results are consistent with high-level face representations that pool local shape and reflectance patterns into configurations that specify facial appearance over a range of three-dimensional viewpoints. These findings have implications for computational models of face recognition and for competing neural theories of face and object recognition.
