Abstract
Recognition for facial identity, expression, and orientation was investigated in a successive face comparison task. Subjects were required to make same/different judgements about pairs of face photographs that could differ in any one of these respects. Overall recognition performance for identity alterations was superior to that for expression and orientation changes. After a short retention interval (1 s) there was no difference between recognition accuracy for different responses to identity, expression and orientation alterations, but after a long delay (20 s) some expression and orientation information was forgotten while accuracy for identity judgements remained unchanged. Subjects could remember some expression and orientation information over a 20 s period, but memory for these dynamic attributes was less durable than identity memory.
