 Abstract: In the real world faces move in a variety of ways, some of which are to do with their signal-sending functions (smiling, nodding, and speaking) and some with other functions (looking, chewing). Information provided by dynamic (timevarying) parameters is known to be particularly salient in the understanding of speech and interpretation of emotional expressions. Additionally, dynamic information from the face seems to provide important information when recognising a person’s identity (Knight & Johnston, 1997; Lander & Bruce, 2000). Here, we report a number of experiments, using personally familiar faces, designed to investigate which aspects of motion are beneficial for the recognition of identity—rigid head movements? expression type movements? speech movements? Recent work has suggested that the eyes are particularly important for face processing. However, in terms of motion, it is the mouth area that moves the most. Our results suggest that benefits of motion can be found when viewing just the top or bottom half of the face (rest of face blacked out), indicating that motion advantages are not confined to one part of the face. Results are discussed in relation to current models of face recognition. Furthermore, we consider the possibility that the representations underlying recognition are themselves dynamic in nature (Freyd, 1987).
