Mean ratings indicating confidence that the target appeared (ratings 6–9, with 9 being the highest confidence), or did not appear (ratings 1–4, with 4 being the highest confidence), at a probed location. All error bars represent the standard error of the mean. a. Mean confidence ratings for target-absent trials, including mean on-probe (i.e., a probe corresponding to the location of a fixated distractor; diamond marker) ratings, mean off-probe (i.e., a probe corresponding to the location of a non-fixated distractor; square marker) ratings, and on-probe ratings as a function of the number of fixated intervening objects (circle markers). b. Off-probe ratings (target-absent trials) as a function of mean distance from the nearest fixated object location. c. Mean confidence ratings for target-present trials on which the target was found, including mean on-probe ratings for target locations (diamond marker), mean off-probe ratings for distractor locations (square marker), and on-probe ratings for distractor locations as a function of the number of fixated intervening objects (circle markers). d. Off-probe ratings (target-present trials) as a function of mean distance from the nearest fixated object location for trials on which the target was found.
