Spatial Cueing • Dependant Variable: Reaction time • Results Reaction time

Valid Invalid Valid Invalid REALY short SOA Not too short SOA
Valid Invalid Valid Invalid REALY short SOA Not too short SOA 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
Attentional Blink Results 1st letter 2nd letter Correct detections Seconds in between 1st and 2nd letter
