Fig. 6

Comparison of BrainDriver race times obtained in different periods of the BCI training. Coloured dots displayed in the boxplots indicate race time values obtained from ten BrainDriver races during the period indicated in the horizontal axis (i.e., in ten runs after the beginning of the training phase, ten runs before the end of the training phase, ten runs after the beginning of the pre-competition phase, and ten runs after the beginning of the competition phase, for both 2019 and 2020, years). The box extends from the lower to upper quartile values, with a line at the median. The whiskers extend from the box to show the range of displayed race time values. p values obtained from paired-sample t-tests are also presented
