Inversion disrupts encoding of faces because of the disruption of configural encoding as evident in the Thatcher illusion (Thompson 1980, Perception 9 483 – 484). Here we consider the effect of rotation on the loss of configural encoding in a same/different matching paradigm. Participants decided whether two faces were of the same type (both normal or both Thatcherised) or not, at five angles of rotation (0°, 45°, 90°, 135 deg, 180°). When the faces were both of the same person, the disruption due to rotation for ‘same-type’ judgments was linear and approximately equal for normal and Thatcherised face pairs. In experiment 2, with different-person face pairs, the effect of rotation was much greater for Thatcherised face pairs than for normal face pairs. These findings are in contrast to those reported by Boutsen and Humphreys (2003, Quarterly Journal of Experimental Psychology A 56 955 – 975), and reasons for these differences, along with implications, are discussed.
