For flexibility, there was further a three-fold interaction effect of tDCS condition, d ’delta90, and pre-tDCS score ( F (1,19) = 8.251, p = 0.010, p Eta 2 = 0.303) as well as marginally significant effects of d ’delta50 ( F (1,19) = 3.6986, p = 0.070, p Eta 2 = 0.163) and the interaction between tDCS condition, RTdelta90, and baseline values ( F (1,19) = 3.0695, p = 0.096, p Eta 2 = 0.139).
