Integrity of blinding
When the participants were asked to guess the nature of the tDCS conditions (active and sham), responses related to the active and sham interventions were included:
All active tDCS groups: active (n=16), sham (n=0), unsure (n=0); and sham group: active (n=16), sham (n=0), unsure (n=0). The differences in the active and sham guesses among the groups were not significant (x2=0.00, d.f.=1, p=0.97).
