Recognizing familiar faces requires a comparison of the incoming perceptual information with mental face representations stored in memory. Mounting evidence indicates that these representations adapt quickly to recently perceived facial changes. This becomes apparent in face adaptation studies where exposure to a strongly manipulated face alters the perception of subsequent face stimuli: original, non-manipulated face images then appear to be manipulated, while images similar to the adaptor are perceived as “normal.” The face adaptation paradigm serves as a good tool for investigating the information stored in facial memory. So far, most of the face adaptation studies focused on configural (second-order relationship) face information, mainly neglecting non-configural face information (i.e., that does not affect spatial face relations), such as color, although several (non-adaptation) studies were able to demonstrate the importance of color information in face perception and identification. The present study therefore focuses on adaptation effects on saturation color information and compares the results with previous findings on brightness. The study reveals differences in the effect pattern and robustness, indicating that adaptation effects vary considerably even within the same class of non-configural face information.

识别熟悉的面孔需要将传入的感知信息与存储在记忆中的心理面孔表征进行比较。越来越多的证据表明，这些表征会迅速适应最近感知到的面部变化。这在面部适应研究中变得明显，其中暴露于强烈操纵的面部会改变对随后面部刺激的感知：原始的、未操纵的面部图像随后似乎被操纵，而类似于适配器的图像被感知为“正常”。面部适应范式是研究存储在面部记忆中的信息的好工具。到目前为止，大多数人脸适应研究都集中在配置（二阶关系）人脸信息上，主要忽略了非配置人脸信息（即不影响空间人脸关系），例如颜色，尽管一些（非适应性）研究能够证明颜色信息在面部感知和识别中的重要性。因此，本研究侧重于对饱和度颜色信息的适应效应，并将结果与​​先前关于亮度的发现进行比较。该研究揭示了效应模式和稳健性的差异，表明即使在同一类非配置人脸信息中，适应效应也存在很大差异。
