Face perception is susceptible to contextual influence and perceived physical similarities between emotion cues. However, studies often use structurally homogeneous facial expressions, making it difficult to explore how within-emotion variability in facial configuration affects emotion perception. This study examined the influence of context on the emotional perception of categorically identical, yet physically distinct, facial expressions of disgust. Participants categorized two perceptually distinct disgust facial expressions, "closed" (i.e., scrunched nose, closed mouth) and "open" (i.e., scrunched nose, open mouth, protruding tongue), that were embedded in contexts comprising emotion postures and scenes. Results demonstrated that the effect of nonfacial elements was significantly stronger for "open" disgust facial expressions than "closed" disgust facial expressions. These findings provide support that physical similarity within discrete categories of facial expressions is mutable and plays an important role in affective face perception.

面部知觉易受上下文影响和情绪线索之间感知到的物理相似性的影响。然而，研究通常使用结构上同质的面部表情，这使得很难探究面部配置在情绪内的变化如何影响情绪知觉。本研究考察了情境对分类上相同但在物理上不同的厌恶表情的情绪知觉的影响。参与者对两种感知上不同的厌恶表情（“闭合”[即，皱鼻子，闭着嘴]和“张开”[即，皱鼻子，张嘴，伸出舌头]）进行了分类，这些表情嵌入了由情绪姿势和场景组成的情境中。结果表明，对于“张开”的厌恶表情，非面部元素的影响明显强于“闭合”的厌恶表情。这些发现支持了在离散的面部表情类别中，物理相似性是可改变的，并在情感面部知觉中起着重要作用。（PsycINFO 数据库记录（c）2019 APA，保留所有权利）。
