Table 3. Effects of METH on memory accuracy for each valence category and for all categories combined (Total) among adequate and poor sleepers in the consolidation group.

	Consolidation group
	Adequate sleepers (n = 17)				Poor sleepers (n = 14)
Dose	Positive	Neutral	Negative	Total	Positive	Neutral	Negative	Total
Placebo	.94 (.02)	.91 (.02)	.93 (.01)	.93 (.01)	.83 (.04)	.81 (.05)	.89 (.04)	.85 (.04)
10 mg METH	.95 (.02)	.91 (.02)	.94 (.02)	.93 (.02)	.81 (.05)	.81 (.06)	.85 (.06)	.82 (.06)
20 mg METH	.95 (.01)	.92 (.02)	.95 (.01)	.94 (.01)	.86 (.04)	.84 (.05)	.89 (.05)	.86 (.04)

Note. Data are mean recognition accuracy (SEM) for studied pictures. Participants were categorized as adequate sleepers if they self-reported 6 or more hours of sleep following the 20 mg dose, and they were categorized as poor sleepers if they self-reported less than 6 hours of sleep following the 20 mg dose.
