Frequency based modulation of singleton suppression is contingent on task difficulty

The data set is from a series of two eye tracking experiments testing the role of trial-wise monitoring induced by frequency manipulation on the suppression of singleton distractors during active visual search. The trial reports were used for reaction time and accuracy analysis and the fixation report was used for dwell time analysis. The experiment has a distractor (present vs absent) and block (20,50,80) within-subjects design.
