Multiple Spatial Changes in Face Perception: Geometric Effects in Inversion and Prosopagnosia

Face recognition is impaired when faces are inverted and disrupted in prosopagnosia. The degree to which perceptual rather than mnemonic mechanisms are impaired by inversion and prosopagnosia is unsettled. Prior studies suggest that the spatial relationships between facial features is important to face recognition, and that faces are perceived 'holistically', integrating featural and spatial data to derive the structure of the entire face.
