Results of Experiment 5: Mean search times (y-axis) for 10 observers as a function of set size (x-axis). The target-present data are presented in black, the target-absent data in gray. Squares represent the search times for the conflict target conditions; the solid lines are linear fits for the search times in these conditions. Diamonds represent the search times for the conflict distractors conditions; the dashed lines are linear fits for the search times in these conditions. Error bars represent standard errors of the means. The results show that search for a conflict target among nonconflict distractors is more efficient than search for a nonconflict target among conflict distractors. However, search for a conflict target is not efficient, nor is there a significant search asymmetry
