ABSTRACT
Old/new recognition task. The old/new recognition task immediately
followed the encoding task. Participants were presented with 80 full-front
faces (08) successively in a random order. These 80 faces included the 40 faces (20 Asians, 20 Caucasians) previously seen in the same/different
matching task (‘‘old’’ faces) and 40 ‘‘new’’ faces (i.e., the other half of our
sets of faces: 20 Asians, 20 Caucasians, half males). Participants were
instructed to decide whether each face was ‘‘old’’ or ‘‘new’’ by pressing one
of two keyboard keys (with mapping of key to response counterbalanced
across participants) as quickly and as accurately as possible. Each face was
presented until the participants responded or for a maximum of 2000 ms.
Participants were not informed of the proportion of old and new faces, and
they did not receive any feedback for their responses.
