 Abstract: Several previous studies have stressed the importance of configural information in face recognition. In this study the perception of configural information was investigated. Using the method of adjustment Experiment 1 revealed that the inter-eye distance is overestimated by 15 percent and the eye-mouth distance by more than 30 percent. In Experiment 2 this effect was replicated using a different set of stimuli. In Experiment 3 several possible explanations were tested: Horizontal vertical illusion, Muller-Lyer illusion, Oppel-Kundt illusion, context effects, Pragnanz effect, and the role of surface information. Experiment 4 consisted of a replication in which a face and a line drawing was used in order to test for surface based face specific effects. The results of these four experiments suggest an important role of well-known perceptual illusions for the explanation of the large overestimation of configural information in faces.
