人们一直在争论面部表情是分类识别还是维度识别。我们使用三组变形的照片面部图像（快乐到愤怒，惊讶和悲伤）来研究这个问题。我们感兴趣的是范畴知觉的实验数据是否可以用维度的观点来解释。实验1研究了由FACS产生的面部刺激。在实验2中，受试者被要求区分几对面孔，并一次对所表现出的情绪进行分类。类别间的判别准确率高于类别内的判别准确率。在实验三中，被试被要求评价这些刺激的语义差异技术。然后，我们研究了实验2中获得的区分准确率和实验3中获得的语义距离之间的关系，语义距离定义为因素空间中的刺激对之间的欧氏距离，构成两个因素解释为“愉快”和“活动”。每个类别内的歧视准确性增加的功能的语义距离，而类别之间的歧视准确性仍然很高，无论不同的语义距离。
It has been argued whether the facial expression is recognized categorically or dimensionally. We investigated this issue using three sets of morphed photographic facial images (happiness to anger, surprise, and sadness). Our interest is whether the experimental data of categorical perception can be explained by the dimensional point of view. Experiment 1 examined the facial stimuli generated by FACS. In Experiment 2, subjects were asked to discriminate some pairs of faces and to categorize the emotion shown one at a time. The discrimination accuracy between categories was better than that within each category. In Experiment 3, subjects were asked to rate those stimuli following the semantic differential technique. Then we examined the relationship between the discrimination accuracy obtained in Experiment 2 and the semantic distances obtained in Experiment 3, defined by Euclidean distances between pairs of stimuli in the factor space that was constituted two factors interpreted as "pleasantness" and "activities". Discrimination accuracy within each category increased as a function of the semantic distances, whereas discrimination accuracy between categories remained high irrespective of the different semantic distances.
