As the bias estimation depends on reliable psychometric function fitting for each participant under all conditions, it is crucial for participants to perform within a reasonable percentage correctness range. Hence, we excluded participants with a low percentage of correct performance (<65%). In Experiment 1, the criterion was applied to the overall performance of the participant since only one condition was presented in the experiment, all 14 participants passed this assessment and were included in the analysis. For Experiment 2, the criterion was applied for each condition separately, and six out of the 22 participants were excluded, as their performance in at least one of the conditions was below the 65% cutoff.
