Confidence and accuracy in facial memory: further evidence for the optimality hypothesis.
In two experiments in which task difficulty was manipulated via inversion or the presence of spectacles, 41 subjects provided recognition and confidence judgments for faces seen earlier. Subjects were more confident when correct than when incorrect, and the difference was greater when the task was easier. These results confirm the optimality hypothesis.
