Table 2.

Detailed results for each participant and session. The first 2 columns list the name of the participant and the number of sessions. The third, fourth, and fifth columns show, respectively, the peak accuracy (%), average accuracy (%), and chance level (%) obtained considering the U repetitions following the last T of each session. The sixth column shows the result of the comparison via confidence intervals (α = 0.05) between the average accuracy and p ₀ (yes = the average accuracy is significantly different from chance; no = otherwise). The seventh column finally refers to the ITR (bits/min) of the corresponding session. In case C phase was reached, the last 4 columns show, respectively, the average accuracy (%), the chance level p ₀ (%), the result of comparison between the two (α = 0.05), and the ITR (bits/min) considering the three repetitions of C.
