		Sleep group	Wake group
Adaptation	Vigilance	443.88 ± 11.86	437.76 ± 8.12
Training	SSS	3.08 ± 0.17	3.15 ± 0.21
	Vigilance	448.56 ± 9.45	449.44 ± 8.16
Test	SSS	2.63 ± 0.21	2.56 ± 0.24
	Vigilance	441.41 ± 9.67	443.53 ± 9.83
	Chronotype	2.88 ± 0.09	2.94 ± 0.10
	Corsi (block span)	6.50 ± 0.33	6.12 ± 0.33
	Corsi (supra span)	3.25 ± 0.58	2.71 ± 0.60

Mean ± SEM are shown. Vigilance is measured as reaction time (ms). Chronotype is measured based on the MEQ and ranges from 1 (definitely evening type) to 5 (definitely morning type). The Corsi block span is a measure for the number of visual items that can be remembered in sequence; the supra span test examines the number of repetitions needed until a sequence of visual items is learned implicitly. SSS, Stanford Sleepiness Scale (7-point-scale on sleepiness). N = 16 and 17 for Sleep and Wake groups, respectively.
