Number of blocks realised by each subject per phase of Experiment 1 (60 trials for phase 1, 120 otherwise). For instance, ARIELLE realised 28 blocks of 60 trials before reaching criteria and moving to phase 2 of the experiment. Note that the number of times the criterion was reached by a subject is the last experimental phase minus one (e.g., eight for FEYA). The means refer to the grand mean for the subjects that passed the criterion at least once (N = 15) or four times (N = 10).
