Analysis of interference effects comparing nontarget picture processing in the active task with passive viewing as the control condition

	Erotica–people		Mutilation–people
	Control	Task	Control	Task
Posterior negative potentials	Δ−4.2	Δ−4.5	Δ−0.9	Δ−1.3
Late positive potential	Δ 1.3	Δ 0.8	Δ 0.7	Δ 0.5

Data are difference scores (high- vs low-arousing pictures) in microvolts collapsed across left and right sensor clusters.
