| Abstract: | A training experiment was carried out to examine whether feedback concerning the appropriateness of confidence judgments, given in terms of probability, improves calibration and resolution skills. Subjects participated in four separate sessions in which they responded to a series of general knowledge questions. Immediately before completing the questionnaires in Sessions 2, 3, and 4, half of the subjects were given detailed feedback concerning their confidence levels and accuracy rates. The remaining half were given no such feedback, and thus served as a control group. The resolution of confidence judgments improved across sessions to a greater extent for the group exposed to performance feedback than for the control group. Calibration of confidence judgments was uninfluenced by the performance feedback manipulation. |
