最近的理论解释认为，概念知识与面部线索的加工动态地相互作用，从根本上影响对社会和情绪类别的视觉感知。越来越多的证据支持这样一种观点，即知觉者关于情感的概念性知识与情感感知有关，即使刻板的面部表情是孤立呈现的(1-4)。然而，现有的方法还不能全面评估不同个体和情绪类别之间的概念知识和情绪感知之间的关系。在这里，我们使用表征相似性分析的方法来表明，概念知识预测面部情绪知觉的表征结构。我们使用计算机鼠标跟踪(5)和反向相关6范式进行了三项研究。总体而言，我们发现，当个体认为两种情绪在概念上更相似时，来自这些类别的面孔被感知到具有相应的相似性，即使控制了刺激本身的任何物理相似性。当情绪在概念上被评为更相似时，情绪感知过程中的计算机-鼠标轨迹对两个类别的反应显示出更大的同时吸引力(尽管只描述了一种情绪；研究1和2)，而反向相关的面孔原型显示出更大的视觉相似性(研究3)。总而言之，我们的发现表明，概念性知识的差异反映在面部情绪的知觉加工中。
Recent theoretical accounts argue that conceptual knowledge dynamically interacts with processing of facial cues, fundamentally influencing visual perception of social and emotion categories. Evidence is accumulating for the idea that a perceiver's conceptual knowledge about emotion is involved in emotion perception, even when stereotypic facial expressions are presented in isolation(1-4). However, existing methods have not allowed a comprehensive assessment of the relationship between conceptual knowledge and emotion perception across individuals and emotion categories. Here we use a representational similarity analysis approach to show that conceptual knowledge predicts the representational structure of facial emotion perception. We conducted three studies using computer mouse-tracking(5) and reverse-correlation6 paradigms. Overall, we found that when individuals believed two emotions to be conceptually more similar, faces from those categories were perceived with a corresponding similarity, even when controlling for any physical similarity in the stimuli themselves. When emotions were rated conceptually more similar, computer-mouse trajectories during emotion perception exhibited a greater simultaneous attraction to both category responses (despite only one emotion being depicted; studies 1 and 2), and reverse-correlated face prototypes exhibited a greater visual resemblance (study 3). Together, our findings suggest that differences in conceptual knowledge are reflected in the perceptual processing of facial emotion.
