许多研究表明，面部表情的识别是由两个基本的两极维度，即愉悦-不愉悦和唤醒强度的几何表示的。在特定条件下，利用原型面孔发现了由这两个维度所界定的心理空间;然而，问题出现了，这个二维的心理空间是否也是对情绪强度较低的面孔的准确表示。为了测试这个，我们准备了四种不同的情绪强度条件。（100%，75%，50%和25%的情绪）的六个基本的面部表情使用变形。参与者（29人为100%，30人为75%，35人为50%，34人为25%的条件）在每种条件下对面部刺激进行了6分制的“根本没有”和“非常如此”。每个条件的多维标度清楚地表明了一个二维表示，多重相关性显示了条件之间的显著相似性（p < .001）。这表明，二维表示的面部表情识别是鲁棒的。
Many studies have indicated that recognition of facial expression is geometrically represented in terms of two underlying bipolar dimensions, pleasure-displeasure and the intensity of arousal. A psychological space defined by these two dimensions has been found under particular conditions using prototype faces; however, the question arises whether this two-dimensional psychological space is also an accurate representation for faces with lower emotional intensity To test this we prepared four different conditions of emotional intensity (100%, 75%, 50%, and 25% of emotionality) for six basic facial expressions using morphing. Participants (29 for the 100%, 30 for 75%, 35 for 50%, and 34 for the 25% condition) in each condition rated the facial stimuli on a 6-point scale of “not at all” and “very much so”. Multidimensional scaling for each condition clearly indicated a two-dimensional representation, and multiple correlations showed significant similarity across conditions (p < .001). This shows that the two-dimensional representation of recognition of facial expression is robust.
