Abstract:
Recent research has shown that stimulating right lateral prefrontal cortex (rLPFC) via transcranial direct current stimulation (tDCS) changes social norm compliance in economic decisions, with different types of compliance affected in different ways. More broadly considering the norms involved in decision-making, and in particular expectations held by players, can help clarify the mechanisms underlying these results.
