Experiment 3: Mean Proportions of Errors (SDs) as a Function of Action-Target Proportion in Combination with Cognitive Load

	Misses			False alarms

	High load	Low load	Difference	High load	Low load	Difference
	Mp (SDp)	Mp (SDp)		Mp (SDp)	Mp (SDp)
High action-target proportion	.62 (.02)	.44 (.02)	.19^***	.16 (.02)	.16 (.03)	0
Low action-target proportion	.49 (.02)	.24 (.03)	.25^***	.04 (.02)	.02 (.02)	.02^***
Difference	.13^***	.21^***		.13^***	.14^***

F Action-target proportion	53.36^***	η² = .83		224.91^***	η² = 3.51
F Cognitive load	140.78^***	η² = 2.20		11.24^***	η² = .18
F Interaction	8.84^***	η² = .14		7.32^***	η² = .11
df	1, 64			1, 64

Note. Mp: mean proportion of errors over relevant task trials; SD: standard deviation. Trials were 50% go trials and 50% no go trials. Differences were calculated by subtracting the second mean from the first, and stars represent the significance of the contrast.

p < .001. η² = F (k-1)/(n-k)
