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.

IVs you could add to spatial cueing task
• Type of cue (central or peripheral)• SOA• Target appears Left vs. right• 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
