目的：看到运动中的人脸可以提高普通人群的人脸识别能力，人脸匹配的研究表明，有人脸识别困难的人（发育性面孔失认症; DP）可能能够使用运动线索作为辅助策略来帮助他们处理人脸。然而，在DP中使用面部运动线索还没有在熟悉的人脸识别的背景下进行研究。这项研究调查了DP患者是否更善于识别运动中的名人面孔，而不是静态的。方法：9名DP参与者和14名年龄匹配的对照者完成了一项著名的人脸识别任务。每个人的脸在2个块中呈现两次：一次是运动图像，一次是静止图像。计算每个块的辨别力（A）。结果：DP参与者总体上表现出显着的运动优势。这是由第一个街区的移动优势驱动的，但不是在第二个街区。DP参与者在从静态图像中识别人脸方面明显比对照组差，但DP参与者和对照组在运动图像中没有差异。结论：在运动中看到熟悉的面孔可以改善DP患者的面部识别，至少在某些情况下。这种效应背后的机制尚不清楚，但这些结果表明，一些患有DP的人能够学习和识别面部运动模式，当面部识别受损时，运动可以作为有用的线索。
Objective: Seeing a face in motion can improve face recognition in the general population, and studies of face matching indicate that people with face recognition difficulties (developmental prosopagnosia; DP) may be able to use movement cues as a supplementary strategy to help them process faces. However, the use of facial movement cues in DP has not been examined in the context of familiar face recognition. This study examined whether people with DP were better at recognizing famous faces presented in motion, compared to static. Methods: Nine participants with DP and 14 age-matched controls completed a famous face recognition task. Each face was presented twice across 2 blocks: once in motion and once as a still image. Discriminability (A) was calculated for each block. Results: Participants with DP showed a significant movement advantage overall. This was driven by a movement advantage in the first block, but not in the second block. Participants with DP were significantly worse than controls at identifying faces from static images, but there was no difference between those with DP and controls for moving images. Conclusions: Seeing a familiar face in motion can improve face recognition in people with DP, at least in some circumstances. The mechanisms behind this effect are unclear, but these results suggest that some people with DP are able to learn and recognize patterns of facial motion, and movement can act as a useful cue when face recognition is impaired.
