    In a face recognition, mini-lineup experiment we examined two aspects of the use of confidence about lineups. We modified the lineup procedure attempting to eliminate the difference in confidence-accuracy relationship between positive (old or identification) and negative (new or not present) decisions. In the modified procedure, participants: (1) selected the lineup member that best matched their memory of the target; (2) rated their confidence that the best match was indeed the target; and (3) indicated (. yes/. no) whether the best match was the target. Although the modified procedure produced higher accuracy than a standard simultaneous procedure, there was no evidence that it affected the confidence-accuracy relationship. Additionally, the modified procedure also allowed us to compare the extent to which confidence ratings versus binary recognition decisions better discriminated studied from unstudied faces. The results revealed a clear advantage for confidence, but indicated that binary responses were also a unique predictor.
