The "spatial congruency bias" is a behavioral phenomenon where 2 objects presented sequentially are more likely to be judged as being the same object if they are presented in the same location (Golomb, Kupitz, & Thiemann, 2014), suggesting that irrelevant spatial location information may be bound to object representations. Here, we examine whether the spatial congruency bias extends to higher-level object judgments of facial identity and expression. On each trial, 2 real-world faces were sequentially presented in variable screen locations, and subjects were asked to make same-different judgments on the facial expression (Experiments 1-2) or facial identity (Experiment 3) of the stimuli. We observed a robust spatial congruency bias for judgments of facial identity, yet a more fragile one for judgments of facial expression. Subjects were more likely to judge 2 faces as displaying the same expression if they were presented in the same location (compared to in different locations), but only when the faces shared the same identity. On the other hand, a spatial congruency bias was found when subjects made judgments on facial identity, even across faces displaying different facial expressions. These findings suggest a possible difference between the binding of facial identity and facial expression to spatial location. (PsycInfo Database Record (c) 2020 APA, all rights reserved).
“空间一致性偏差”是一种行为现象，即如果两个依次呈现的物体出现在相同位置，它们更有可能被判断为同一个物体（戈洛姆、库皮茨和蒂曼，2014年），这表明不相关的空间位置信息可能与物体表征相关联。在此，我们研究空间一致性偏差是否扩展到对面部身份和表情的更高层次物体判断。在每次试验中，两张真实世界的面孔依次出现在不同的屏幕位置，要求受试者对刺激的面部表情（实验1 - 2）或面部身份（实验3）做出相同或不同的判断。我们观察到对面部身份判断存在强烈的空间一致性偏差，而对面部表情判断的偏差则较为微弱。如果两张面孔出现在相同位置（与出现在不同位置相比），受试者更有可能判断它们显示相同的表情，但前提是面孔具有相同的身份。另一方面，当受试者对面部身份进行判断时，即使面对显示不同面部表情的面孔，也会发现空间一致性偏差。这些发现表明面部身份和面部表情与空间位置的关联可能存在差异。（PsycInfo数据库记录（c）2020美国心理学会，保留所有权利）
