Face adaptation aftereffects with local feature information
Final Report Abstract
Experiments investigating our ability to adapt to manipulations in faces – so-called face adaptation aftereffects – (systematically investigated by Webster and MacLin, 1999, for the first time) repeatedly have shown that inspecting manipulated faces (so-called adaptor faces) leads to changes of the perception of subsequently presented faces: Typically, original images are then perceived as manipulated in the opposite direction of the adaptor while images that are more similar to the adaptor are perceived as normal. Face adaptation effects are found to be highly robust and sustainable. Most studies so far used manipulations of configural information in faces (i.e., information related to spatial relations) when investigating these adaptation effects. Face research, however, also tells us that other facial features play a role in face processing as well, for instance, feature information, texture, or color. The central aim of this DFG project was to investigate local (i.e., non-configural) face adaptation aftereffects. Results showed remarkable adaptation effects to facial manipulations such as color brightness and saturation and more ecologically valid manipulations to faces such as complexion or freckles. Also, results show (similar to configural manipulations) transferability and robustness over time. Our results extend the theoretical framework of face adaptation aftereffects towards local (non-configural) facial information and reveal the (long neglected) importance of non-configural face information for face memory and recognition.
