論文The current study was designed to explore the relation between accuracy and confidence on composite picture recognition. Forty eight participants intentionally learned a set of 48 facial photos. After the learning phase, participants in the immediate group immediately gave the old-new judgments as well as the confidence rating about each judgment, while participants in the delayed group did so one day later. The faces used in the test phase included old faces, new faces, and conjunction faces. Conjunction faces as composite pictures were made from facial parts of the different faces which were presented during the learning phase. In the immediate group, there was not a correlation between accuracy and confidence rating on recognition of conjunction faces （γ =.11）. In the delayed group, there was a negative correlation between accuracy and confidence rating on recognition of conjunction face（γ =-.21）. Though confidence rating is often used as a predictor of eyewitness memory accuracy, the result suggested that the confidence is not a good predictor of accuracy on composite picture recognition.
