A 2 × 2 repeated-measures ANOVA was run for the first experiment with Hand (left/right hand) and Stimulation condition as within-subject factors. A 3 × 2 × 2 mixed-factor ANOVA was run for the second experiment with Stimulation group as a between-subject factor and Hand and Stimulation condition as within-subject factors.
