Note. The baseline assessment in the first session and the pre training assessment in the second session were merged to one pre training measure. Please note. The second line for each group of the variable judgment tendency indicates the Mdn and IQR for the absolute judgment tendency values (absolute difference to an ideal criterion of 0).
