Transcranial direct current stimulation of the rLPFC shifts normative judgments in voluntary cooperation

In this study, we used a linear asymmetric public good game to investigate the role of normative judgment in voluntary cooperation with tDCS on rLPFC. Participants were engaged in anonymous social interactions and made decisions with real financial consequences after being randomly assigned to receive either anodal, cathodal, or sham stimulation of 15 min. Results suggest that compared with the sham group, anodal/cathodal tDCS influenced the behavior and normative judgment of participants in opposite directions. These outcomes provide a neural evidence for the rLPFC mechanism on normative judgment in voluntary cooperation.
