Abstract

Facial recognition performance was examined as a function of changes in the target between initial exposure (study) and a subsequent recognition test. Photographic mode (colour vs. black and white) was changed in Experiments 1 and 2 and pose (front vs. profile) was changed in Experiment 2. The predictions of three information quantity models and of encoding specificity were contrasted. The information hypotheses predict that colour photographs will be better recognized when presented in colour than in black and white; the more specific predictions differ depending on the modes at study and test. Encoding specificity predicts recognition performance will be better when study and test modes are the same. The results of Experiment 1 showed that performance was highest when pictures remained in the same mode from study to test, and decreased when the mode was changed. Change of mode was particularly detrimental when the faces were studied in black and white and tested in colour. Experiment 2 showed a pattern of results also in accord with encoding specificity. The photographic mode and pose effects did not interact. Change of pose had a greater effect than change of photographic mode. Experiment 2 did not replicate the transformation asymmetry found in Experiment 1. The results indicate that for facial recognition memory, change lowers recognition, but the magnitude of the effect depends on the kind of change.
