Perceptual Processes of Face Recognition: Single feature orientation and holistic information contribute to the face inversion effect
Abstract
In this study (n=144) we investigated the perceptual processes that are the basis of the face inversion effect (better recognition for upright vs inverted faces). We evaluated the effects of disrupting configural information (i.e., the spatial relationships among the main facial features) and disrupting holistic information indexed by the face outline. We used scrambled faces which are characterized by a disruption of configural information and scrambled no-contour faces which in addition to disrupted configural information they also suffered of disruption of the face outline. Using an old/new recognition task we obtained a robust inversion effect for scrambled faces. No significant inversion effect was found for scrambled no-contour faces. Our results provide direct evidence that holistic information plays a significant role in the inversion effect. We also confirmed that it is possible to obtain a robust inversion effect when configural information is disrupted.
