A Graphical representation of the computation of the correlation index between metacognitive evaluations and head-related behaviors across trials. B Correlation values obtained considering effort in the actual vs. permutation sequences of trials as a function of the trial time (CT − 2, CT − 1, CT, CT + 1, CT + 2). C Correlation values obtained considering confidence in the actual vs. permutation sequences of trials as a function of trial time (CT − 2, CT − 1, CT, CT + 1, CT + 2)
