Table 1. Behavioral results when predicting RT from stimulation condition (compared to sham tRNS, which serves as the reference), day, and learning type.

Statistics: Value = regression coefficient, SE = standard error, DF = degrees of freedom, T =  t -value, p =  p -value, dlPFC = dorsolateral prefrontal cortex, PPC = posterior parietal cortex, tRNS, transcranial random noise stimulation. Interactions are denoted by the * symbol. The data underlying the results in this table can be found in S1 Data .
