摘要

Participants encountered same-race and cross-race faces at encoding, completed a series of line-up identification tests and provided confidence ratings by using one of nine different confidence scales. Confidence was less well calibrated with identification accuracy when participants selected a cross-race than a same-race face because of overconfidence. By contrast, there was no cross-race effect on confidence-accuracy calibration when participants responded 'not present'. Whereas confidence was a very strong predictor of accuracy for fast identifications of a line-up face, this was much less the case for slower decisions. Highly confident identifications showed a dramatic drop in accuracy from faster decisions to slower decisions, whereas there was little change in accuracy between faster and slower decisions for moderately confident or weakly confident identifications. Finally, we observed little influence of the format of the nine different confidence scales: numerical and verbal scales produced comparable calibration scores, as did scales with few or many points.
