Table 6. Sensitivity (d′) and criterion values as a function of prior identity decision (threshold = 0.5).

95% confidence intervals are estimated by bootstrap resampling.

Prior	n	d′ (95% CI)	Criterion (95% CI)
None	120	1.39 (1.24–1.55)	0.16 (0.07–0.26)
Same	223	1.24 (1.09–1.38)	0.05 (-0.03–0.13)
Different	223	1.38 (1.23–1.53)	0.27 (0.19–0.36)
