Grand average SMR power (in µV²) of the respective subgroups for electrode Cz across ten training sessions and while watching the feedback bars (baseline), as well as ratings of control beliefs on day one.

EG, experimental group; CG control group; KUT, control beliefs while dealing with technology; SMR, sensorimotor rhythm; SEM, standard error of the mean; note that subgroups “low” and “high” of n = 5 participants were obtained using median split on KUT scores of “all” n = 10 participants..
