Inspecting new visual information in a face can affect the perception of subsequently seen faces. In experimental settings for example, previously seen manipulated versions of a face can lead to a clear bias of the participant’s perception of subsequent images: Original images are then perceived as manipulated in the opposite direction of the adaptor while images that are more similar to the adaptor are perceived as normal or natural. These so-called face adaptation effects can be a useful tool to provide information about which facial information is processed and stored in facial memory. Most experiments so far used variants of the second-order relationship configural information (e.g., spatial relations between facial features) when investigating these effects. However, non-configural face information (e.g., color) was mainly neglected when focusing on face adaptation, although this type of information plays an important role in face processing. Therefore, we investigated adaptation effects of non-configural face information by employing brightness alterations. Our results provide clear evidence for brightness adaptation effects (Experiment 1). These effects are face-specific to some extent (Experiments 2 and 3) and robust over time (Experiments 4 and 5). They support the assumption that non-configural face information is not only relevant in face perception but also in face retention. Brightness information seems to be stored in memory and thus is even involved in face recognition.

人脸自适应对非配置人脸信息的影响

检查面部新的视觉信息可能会影响随后看到的面部的感知。例如，在实验设置中，之前看到的人脸被操纵的版本可能会导致参与者对后续图像的感知出现明显偏差：原始图像被感知为在适配器的相反方向上被操纵，而与适配器更相似的图像被认为是正常或自然的。这些所谓的面部适应效果可以成为一种有用的工具，可以提供有关哪些面部信息被处理并存储在面部记忆中的信息。迄今为止，大多数实验在研究这些影响时都使用二阶关系配置信息的变体（例如，面部特征之间的空间关系）。然而，在关注面部适应时，非配置性面部信息（例如颜色）主要被忽略，尽管此类信息在面部处理中发挥着重要作用。因此，我们通过亮度改变来研究非配置面部信息的适应效果。我们的结果为亮度适应效果提供了明确的证据（实验 1）。这些效果在某种程度上是特定于面部的（实验 2 和 3），并且随着时间的推移而变得稳健（实验 4 和 5）。他们支持这样的假设：非配置面部信息不仅与面部感知相关，而且与面部保留相关。亮度信息似乎存储在内存中，因此甚至参与了人脸识别。
