Editorial: Aftereffects in face processing

Editorial: The original aim of this special issue was to use aftereffects to highlight the different cognitive, perceptual, and neural representations of unfamiliar and familiar faces. Face aftereffects occur due to prolonged exposure to an adaptor face that causes a test face to take on the “opposite” characteristics (e.g., a normal face will appear compressed following adaptation to an expanded face, Webster and MacLin, 1999). The resulting papers went beyond this aim and have demonstrated the extensive potential for theoretical advancement that research on aftereffects can create.
