From: Relaxing learned constraints through cathodal tDCS on the left dorsolateral prefrontal cortex
Relax index (as the percentage of time the problem was solved after having solved that problem once) before (blue) and after (red) cathodal, anodal and sham tDCS for problem types A, B, C, and D. Relax index is the proportion of correct solutions after the problem was solved for the first time. The error bars represent +/−1 S.E.M. Note that for the problem type C there was only one participant in the post-test anodal and one in the sham conditions, which prevented the use of error bars (*).
