  1. Full Model: RT ~ 1 + Constant + RSDl + RSDh + Gender + Stroop + (1|Participants) + (1|Order).
  2. RT reaction time on compound remote associates task, RSDl relative semantic distance lower than the breakpoint, RSDh relative semantic distance higher than the breakpoint, L−R+ cathodal stimulation on F7 and anodal stimulation on F8, SHAM sham control for tDCS.
