Abstract

People find it is easier to recognise the identity of a familiar face in non-optimum viewing conditions when it is moving (smiling, talking), compared to when shown as a static image. Here we explore the theoretical underpinnings of the moving face recognition advantage. Specifically, we compare the identification of personally familiar faces from natural smile sequences (dynamic morphing), artificial smile sequences, single static neutral images and single static smiling images. Results showed recognition was best when the face was viewed naturally smiling. A further
experiment investigated the impact of motion tempo on the
recognition of morphed familiar faces. Results indicate a
significant interaction between the naturalness of the motion and the speed of the observed motion. We conclude that the recognition advantage for face motion does not reflect a general benefit for motion, but instead suggests that, for familiar faces, information about their characteristic motion is stored in memory.
