Mean concealed knowledge effect on RT in milliseconds (probe-irrelevant) and accuracy in percent correct (irrelevant-probe) for the unfamiliar-probe test

Condition	Delay
	10 min	24 h	1 week
RT
Deep	11.17 (12.91)	−13.08 (5.23)	8.43 (7.15)
Shallow	−10.59 (8.10)	1.96 (9.37)	0.94 (12.13)
Accuracy
Deep	0.86% (1.0%)	−0.19% (1.0%)	0.34% (0.50%)
Shallow	1.76% (1.5%)	−0.60% (1.0%)	−0.65% (1.0%)

Positive values indicate that probe responses were slower or less accurate than irrelevant responses. Data are shown as a function of study-test delay and probe study condition
