Results, Experiment 1. (A) Low-probability (LP) cues. Accuracy (proportion correct, mean across participants) is plotted as a function of response time (across-subject mean of the mean correct response times in each response delay condition). Black circles, valid cues. White circles, invalid cues. (B) High-probability (HP) cues. Same format as Panel A. (C) Spatial attention effect, LP cues. The y-axis is the mean within-participant change in accuracy (proportion correct), valid minus invalid, with a bootstrapped 95% confidence interval shown for each response delay condition. The x-axis is on a categorical scale to aid in visual assessment. Each range indicates the bounds of possible response times for that delay condition (delay amount + 500 ms response window). (D) Spatial attention effect, HP cues. Same format as Panel C. (E) Cue validity x cue probability interaction. The y-axis is the mean within-participant change in the spatial attention effect, LP minus HP. Same format as Panel C. *p = 0.0015, with a critical p-value of 0.0071 after Bonferroni correction.
