Schematic task design. Stimulus onset was time-locked to distinct cardiac phases: systole (red) and diastole (blue). The figure shows how the most ambiguous duration (300 ms) did not overlap across the phases. The black bars represent stimulus durations. Participants first learned to discriminate between the short (200 ms) and the long (400 ms) reference, and during bisection, they were presented with additional intermediate test durations.
