Abstract: | Confidence-accuracy calibration was examined for both absolute (recognizing single faces as old or new) and relative (selecting which of pairs of faces is old) judgments, using both full- (0%-100%) and half-range (50%-100%) confidence scales. The half-range confidence scale demonstrated superior calibration to the full-range scale, for which a confidence-accuracy association was evident only for the upper half (i.e., 50%-100%) of the scale. Good calibration was observed for the absolute judgment conditions, but the relative judgment conditions evidenced marked underconfidence. Also, in the absolute judgment conditions, good calibration for positive recognition decisions and poorer calibration for negative decisions was observed. These results are discussed in the context of theories of confidence and accuracy in face recognition memory and also of eyewitness identification research.
