A) Mean confidence reported for each level of coherence. (
B) Mean confidence reported when playing with each partner. The question mark indicates a condition in which the partner’s identity was hidden. (
C) Heat map over mean confidence in each condition of our factorial design (confidence was z-scored for each subject before averaging across subjects). Warmer colours indicate higher confidence. In (
A) and (
B), data are represented as group mean ± SEM. Each dot is a subject.
