Means and variances of bias-corrected acceptance rates [P(Yes)] for NS (new-similar) and O (old) items. O? refers to old probes, and NS? refers to new-similar probes. These are the relations between p(O?) and p(NS?) for strong NS items, weak NS items, and O items in the 1,500 msec condition of Experiment 6 (Panel A) and in the 500 msec condition (Panel B). In Panel A, strong and weak NS performance are completely complementary, whereas O performance is partially complementary and reality-consistent. In Panel B, strong NS performance is partially complementary and reality-reversed, weak NS performance is completely complementary, and O performance is partially complementary and reality-consistent.
