Mean reaction times (ms) across different memory categories in the No-Nap and Nap groups for the 4-h and 15-min study sessions, respectively

Study
		Study session (4 h)		Study session (15 min)
		Emotional	Neutral	Emotional	Neutral
No-Nap	Mean	917	856	936	899
	SEM	171	117	146	120
Nap	Mean	895	773	859	785
	SEM	119	96	126	110
