Results of the four crossed conditions in the main experiment, translated into the capacities K for forward masking (panel A) and backward masking (panel B). (A) Capacity K as a function of forward-mask SOA for enumeration (filled circles) and change detection (open circles). (B) Capacity K as a function of backward-mask SOA for enumeration (filled circles) and change detection (open circles). The vertical dashed line indicates the temporal window of visible persistence (Di Lollo, 1980), where the influence of backward masking switches from integration to interruption masking (Scheerer, 1973; Scheerer & Bongartz, 1973). 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
