The Effects of Transcranial Direct Current Stimulation on Mind-Wandering

- The current study investigated whether transcranial direct current stimulation (tDCS) to the left dorsolateral prefrontal cortex (DLPFC) and the right inferior parietal lobule (IPL) independently influences mind-wandering behavior. Thirty-six participants received offline stimulation at either the left DLPFC (F3) or the right IPL (P4), both with the second electrode over Cz. Within each group, ... read moreparticipants experienced three stimulation conditions on three separate days: anodal/return (F3 or P4/Cz), cathodal/return (F3 or P4/Cz), and sham. When all stimulation conditions were combined, participants in the F3 group reported significantly more task-unrelated thoughts (TUTs) during a monotonous task than those in the P4 group. However, no significant difference in TUTs was found between the stimulation conditions. This finding challenged existing results on tDCS and mind-wandering, but must be interpreted in light of the differences in experimental paradigm and measures of mind-wandering between the current studies and prior literature. These differences, together with limitations and suggested modifications, were discussed.Keywords: mind-wandering, task-unrelated thoughts, transcranial direct current stimulation, prefrontal cortex, parietal loberead less
