人们普遍能识别快乐、悲伤、恐惧、愤怒、厌恶，也许还有惊讶的面部表情，这表明一种感知机制与显示每种情绪的面部结构相协调。一组图画由计算机生成，每组图画由一系列不同的面孔组成，这些面孔的物理量是恒定的，从一种情感表达到另一种情感表达（或从一种情感表达到一个中性面孔）。受试者区分成对的面孔，然后在一个单独的任务中，对每个面孔所显示的情绪进行分类。同一类别中的面孔比不同类别中的面孔更难区分，不同类别中的面孔相差相同的物理量。因此，情感表达，像颜色和语音一样，是被分类感知的，而不是它们连续的物理属性的直接反映。
People universally recognize facial expressions of happiness, sadness, fear, anger, disgust, and perhaps, surprise, suggesting a perceptual mechanism tuned to the facial configuration displaying each emotion. Sets of drawings were generated by computer, each consisting of a series of faces differing by constant physical amounts, running from one emotional expression to another (or from one emotional expression to a neutral face). Subjects discriminated pairs of faces, then, in a separate task, categorized the emotion displayed by each. Faces within a category were discriminated more poorly than faces in different categories that differed by an equal physical amount. Thus emotional expressions, like colors and speech sounds, are perceived categorically, not as a direct reflection of their continuous physical properties.
