Participant characteristics: Pretested individual cognitive control abilities of the different groups

	Control	Depleted
Experiment 1	Vertex n = 18	DLPFC N = 18
Digit span (forward + backward)	18 (min = 11, max = 25)	19 (min = 11, max = 28)
WCST (N perseveration errors)	7 (min = 5, max = 17)	7 (min = 5, min = 11)
Experiment 2	No load (N = 20)	LCL (N = 20)	HCL (N = 20)
Digit span (forward + backward)	18 (10 to 22)	19 (12 to 24)	20 (12 to 29)
ECST (N perseveration errors)	8 (5 to 19)	8 (5 to 17)	7 (5 to 11)
STD (in seconds)	0.91 (0.46 to 1.3)	0.87 (0.50 to 1.4)	0.91 (0.46 to 1.3)

Values represent average scores with minimum to maximum in parentheses. WCST = Winsconsin Card Sorting Test for cognitive reasoning; STD = (pre-tested) Stimulus Time Duration or maximal processing capacity (i.e., the shortest processing time interval to simultaneously perform two working memory tasks while maintaining an accuracy of at least 85%). All group comparisons are non-significant according to independent sample t-tests (Ps > 0.05).
