Sensitivity (A)
Pearson’s r	.126	.142	− .045
p	.148	.101	.605
Bias (b)
Pearson’s r	− .147	− .103	.115
p	.090	.236	.185
Accuracy (matched identity trials)
Pearson’s r	.179	.147	− .126
p	.038	.090	.146
Accuracy (mismatched identity trials)
Pearson’s r	− .042	.063	.023
p	.629	.467	.796

Bold cells indicate a significant correlation, p < .05. Italicised values represent the p values associated with the Pearson's r, regardless of significance
