A Illustrative examples of the three possible Distractor Conditions used to study learned distractor suppression in the additional singleton paradigm. On every trial, participants look for the uniquely shaped object, and respond based on the orientation of the line within it. B Spatial distribution of stimuli in the illustrative display. Percentages show the probability of a singleton distractor (D) or a target (T) appearing at a particular location. C Description of how the measures of Attentional Capture (AC); Learned Distractor Suppression (LDS); and Target Suppression (TS) are calculated. A similar computation can be done for accuracy scores instead of RTs
