The Cost of Matching Depth-Rotated Faces: A Simple Function of Image Similarity

When unfamiliar faces are to be recognized or matched at different orientations in depth, sizeable costs in the speed and accuracy of performance have been documented attributable to the disparity in orientations. There have been no rigorous, quantitative assessments of these costs. Here we evaluated the effects of orientation disparity in a minimal match-to-sample paradigm of a triangular display of three faces, with one of the two test faces...
