Analyses and Statistics
We initially examined a potential effect on RTs of changing between sequence types. We then compared baseline performance between the groups and evaluated whether motor learning took place and was reflected in faster RTs during implicitly learned sequences. Dependencies were then sought between stimulation group and sequence type online and offline. Finally, we examined whether there was a speed–accuracy trade-off. Following evaluation of whether the required assumptions were fulfilled, analyses of variance (ANOVAs) were applied. Greenhouse–Geisser corrections were applied, where Mauchly sphericity was violated with epsilon under 0.75, and Huynh–Feldt corrections were applied when epsilon was greater than 0.75. Bonferroni corrections were applied to the post hoc
