Results of Experiment 3. (a) Mean accuracy (top left panel) and RTs (bottom panel) for the search task as a function of color repetition. The classic IFP effect can be seen in the faster search RTs when the color repeats than switches. (b) Mean accuracy (top panel) and RTs (bottom panel) in probe trials as a function of relative location and color repetition. The stimulus-driven attentional effect, which did not interact with color repetition, can be seen in the faster probe RTs on same-location than different-location trials. Error bars are ±1 within-subject standard error (Morey, 2008). *p < 0.05.
