Table 1.

Mean proportions of practiced and un-practiced information by simulator groups, and retrieval-practice effects at both immediate and delayed memory tests.

	Simulators retrieval practice			Facilitation	RIF
	Rp +	Rp -	Control	(Rp +) – Control	(Rp -) – control
Immediate	0.63 (0.14)	0.34 (0.13)	0.46 (0.16)	0.17 (0.22)	-0.12 (0.23)
After a day	0.68 (0.12)	0.34 (0.14)	0.45 (0.15)	0.23 (0.17)	-0.11 (0.22)

Rp + and Rp - information from the simulator retrieval-practice group are shown. Control displays un-practiced information from simulator control group. Standard deviations are presented between parentheses.
