Testing paradigm. Following the presentation of a text cue, the adapting face was shown for a variable time. At 250 ms prior to replacement of the adapting with the test face, a tone sounded briefly to alert the subject to the impending stimulus. Following removal of the test face, the subject was required to rate the degree to which the final percept matched the cued identity. In the UWA data, there were both match and mismatch trials, according to the correspondence between the cue and the anti-face.
