基于置信度的校准和分辨率指数在两个实验中获得，需要感性的比较，并在第三与视觉间隙检测。获得了四个重要结果。首先，在一般知识领域，受试者是不自信的判断时，容易和过度自信时，他们很难。第二，平行的明确依赖于决策难度的校准，分辨率下降，增加决策难度所产生的下降，无论是从减少的可辨别性或从增加的要求，以牺牲准确性的速度。第三，对困难的任务提供逐个试验的反应反馈可以提高分辨率，但对校准没有影响。第四，受试者可以准确地报告主观错误（即，他们已经表明他们犯了一个错误的试验）与他们的信心评级。它还表明，属性的决策时间，条件化的置信度类别，施加了严格的约束条件的置信度校准理论。
Confidence rating based calibration and resolution indices were obtained in two experiments requiring perceptual comparisons and in a third with visual gap detection. Four important results were obtained. First, as in the general knowledge domain, subjects were underconfident when judgments were easy and overconfident when they were difficult. Second, paralleling the clear dependence of calibration on decisional difficulty, resolution decreased with increases in decision difficulty arising either from decreases in discriminability or from increasing demands for speed at the expense of accuracy. Third, providing trial-by-trial response feedback on difficult tasks improved resolution but had no effect on calibration. Fourth, subjects can accurately report subjective errors (i.e., trials in which they have indicated that they made an error) with their confidence ratings. It is also shown that the properties of decision time, conditionalized on confidence category, impose a rigorous set of constraints on theories of confidence calibration.
