Abstract:
'Face-space' is an abstract concept of the multidimensional representation of faces. Faces of similar appearance are closer in face-space than dissimilar faces; however, it is not clear how representations interact. Examining contrast thresholds for facial recognition, we show that a 200 ms preview of a face facilitates recognition of the same face, but inhibits recognition of other faces, more so for the same ethnic group than for a different ethnic group. This suggests a center-surround organization in which facial representations close to the priming stimulus are more suppressed than those that are distant.
