There was also a trend to show a smaller response bias in the blocked 2-beep trials compared to those of Experiment 1 (interleaved trials), though a post-hoc comparison (Experiment 1 vs Experiment 2) failed to reach significance (2-tailed t -tests, P = 0.16, and P = 0.06 for no-feedback and feedback conditions, respectively).
