From: Do sequential lineups impair underlying discriminability?
Hypothetical ROC curves for two memory test procedures. Procedure B has higher empirical discriminability (AUC) than Procedure A. The dashed lines represent different diagnosticity ratios taking the values 1, 1.5, 2.5, 5 and 10. Each point on each ROC curve that intersects with a line has the corresponding diagnosticity ratio
