Abstract: | ABSTRACT Faces belonging to the same category as the perceiver are better recognised than faces from different categories when tested immediately. After a delay, the same-category benefit persists and response bias becomes more liberal for other-category but not same-category faces. These effects are typically attributed to better encoding of same-category than other-category faces. To determine whether bias effects after a delay persist when immediate accuracy differences are minimised, Hispanic and Caucasian participants were given more study time for other-category than same-category faces. Memory was tested immediately and after a two-day delay. Discrimination accuracy was higher for other-category than for same-category faces during both test sessions. Bias was equivalent immediately, but after the delay, bias was more conservative for same-category than for other-category faces, especially in Caucasian participants. These results suggest that post-encoding processes differentially influence face memories from different categories, which may have implications for evaluating face memory in everyday situations. |
