Results of the four crossed conditions in the main experiment: Forward masking with enumeration (panel A), forward masking with change detection (panel B), backward masking with enumeration (panel C), and backward masking with change detection (panel D). (A) Proportions of correct trials as a function of forward-mask SOA, for different item set sizes during enumeration. For reasons of better comparability to the change detection condition, only performance values for set sizes 2, 4, and 6 are connected with solid lines across the different SOAs. (B) Proportions of correct trials as a function of forward-mask SOA, for different item set sizes during change detection. (C) Proportions of correct trials as a function of backward-mask SOA, for different item set sizes during enumeration. For reasons of better comparability to the change detection condition, only performance values for set sizes 2, 4, and 6 are connected with solid lines across different SOAs. (D) Proportions of correct trials as a function of backward-mask SOA, for different item set sizes during change detection. Error bars display one standard error of the mean for within-subjects designs. Individual performance values were centered on the mean performance of each subject before calculating the standard errors
