While the dissociation between invariant aspects of a face and emotional expressions has been studied extensively, the role of non-emotional changeable aspects in face recognition has been considered in the literature rarely. The purpose of the present study was to understand whether information on changeable aspects (with and without emotional content) can help those individuals with poor face recognition abilities (when based on invariant features) in recognizing famous faces. From a population of 80 university students we selected two groups of participants, one with poor performance (experimental group, EG) and the other with good performance (control group, CG). By means of a preliminary experiment, we selected videos of 16 Italian celebrities that were presented in three different conditions: motionless, with non-emotional expressions, and with emotional expressions. While the CG did not differ in the three conditions, the EG showed a significantly better performance in the two conditions with facial movements, which did not differ between each other. These results suggest a role of changeable aspects in the identification of famous faces, rising only in the case invariant features are not analyzed properly.
虽然面孔的不变特征与情感表达之间的分离已得到广泛研究，但面孔识别中非情感可变特征的作用在文献中很少被提及。本研究的目的是了解关于可变特征（有无情感内容）的信息是否能帮助那些面孔识别能力较差的个体（基于不变特征时）识别名人面孔。我们从80名大学生中挑选出两组参与者，一组表现较差（实验组，EG），另一组表现良好（对照组，CG）。通过初步实验，我们选取了16位意大利名人的视频，并在三种不同条件下呈现：静止、带有非情感表情、带有情感表情。虽然对照组在这三种条件下没有差异，但实验组在面部有动作的两种条件下表现明显更好，且这两种条件下彼此无差异。这些结果表明可变特征在名人面孔识别中起作用，仅在不变特征未被正确分析的情况下才会凸显。
