We investigated the early stages of face recognition and the role of featural and holistic face information. We exploited the fact that, on inversion, the alienating disorientation of the eyes and mouth in thatcherised faces is hardly detectable. This effect allows featural and holistic information to be dissociated and was used to test specific face-processing hypotheses. In inverted thatcherised faces, the cardinal features are already correctly oriented, whereas in undistorted faces, the whole Gestalt is coherent but all information is disoriented. Experiment 1 and experiment 3 revealed that, for inverted faces, featural information processing precedes holistic information. Moreover, the processing of contextual information is necessary to process local featural information within a short presentation time (26 ms). Furthermore, for upright faces, holistic information seems to be available faster than for inverted faces (experiment 2). These differences in processing inverted and upright faces presumably cause the differential importance of featural and holistic information for inverted and upright faces.
我们研究了人脸识别的早期阶段以及面部特征信息和整体面部信息的作用。我们利用了这样一个事实，即在倒置时，撒切尔化面孔中眼睛和嘴巴的异化性错乱几乎难以察觉。这种效应使得特征信息和整体信息得以分离，并被用于检验特定的面部处理假设。在倒置的撒切尔化面孔中，主要特征已经正确定向，而在未变形的面孔中，整体格式塔是连贯的，但所有信息都是错乱的。实验1和实验3表明，对于倒置面孔，特征信息处理先于整体信息。此外，在短呈现时间（26毫秒）内处理局部特征信息时，上下文信息的处理是必要的。此外，对于正立面孔，整体信息似乎比倒置面孔更快可用（实验2）。处理倒置面孔和正立面孔时的这些差异可能导致特征信息和整体信息对于倒置面孔和正立面孔的重要性不同。
