The perception of a face allows us to recognize the person, infer his or her emotional state, better understand what the person is saying, and derive general information, such as age and gender. This unique visual stimulus has generated a wealth of research, and subsequently theoretical and methodological debate. This special issue brings together 16 original papers that show the extraordinary diversity and fruitfulness of the approaches now being pursued. They are aimed at understanding different aspects of face perception in populations ranging from healthy children to adults with brain lesions and with techniques covering the entire spectrum from paper-and-pencil tests to functional brain imaging. Together, these contributions provide an insightful overview of the current state of research on face perception and exemplify the questions that dominate the field. To one such question, whether 'face perception' is a special issue in the broad field of the cognitive neurosciences, the answer is clearly yes!
