Previous research has shown that facial motion can carry information about age, gender, emotion and, at least to some extent, identity. By combining recent computer animation techniques with psychophysical methods, we show that during the computation of identity the human face recognition system integrates both types of information: individual non-rigid facial motion and individual facial form. This has important implications for cognitive and neural models of face perception, which currently emphasize a separation between the processing of invariant aspects (facial form) and changeable aspects (facial motion) of faces.
先前的研究表明，面部运动能够传递有关年龄、性别、情感的信息，并且至少在一定程度上还能传递身份信息。通过将近期的计算机动画技术与心理物理学方法相结合，我们发现，在身份识别的计算过程中，人脸识别系统整合了两种信息：个体的非刚性面部运动和个体的面部形态。这对于面部感知的认知和神经模型具有重要意义，目前这些模型强调面部不变方面（面部形态）和可变方面（面部运动）的处理之间的分离。
