Inhibition of return keeps attention from revisiting
where it has just been.
On valid trials that’s what you have to do – so your
RT is slower.

Any more???
Attentional Blink
• IV: separation between the two targets
--levels (0), 2, 4, 6, 8, seconds
• IV: target order
--levels 1st or 2nd
• DV: Accuracy of detection of targets
