Receiver operating characteristic (ROC) curves of the FRS and participants for the clear and unclear conditions. The shaded regions represent the partial area under the curve (pAUC) regions for each condition, using the cut-off of the overall false ID rate of the FRS clear condition. The error bars are 68% confidence intervals based on 200 bootstraps. The black dashed line represents chance performance. Point sizes reflect relative frequencies of responses
