Correlation coefficient between the R-K predicted zROC slope and the zROC slope observed from the confidence rating data

UVSD DPSD
Data ssa r P ss r P
K&Y Empirical data (p. 1540) 30 .17 .36 31 .56 < .05
UVSD simulated data (N = 100) 30 .15 31 .47
Exp 1 Empirical data 21 .18 .43 22 .49 < .05
UVSD simulated data (N = 100) 21 .30 22 .57

Note. Correlation coefficients were calculated with the individual zROC slopes for each data set (upper row) and averaged across 100 simulated experiments (lower row); R-K = Remember-Know judgments; UVSD = unequal-variance signal-detection model; DPSD = dual-process signal-detection model; K&Y = Koen and Yonelinas (2010); Exp = experiment; ss = number of subjects; N = number of simulated data per subject.

K&Y reported that "One participant was excluded from this analysis because her or his estimated z-slope was greater than five standard deviations from the group mean” (p. 1540). The same was true for the data analysis of Exp 1.
