Abstract  

People often change their opinion and behavior to conform to others. Recent studies in social neuroscience, using social psychological theories and experimental paradigms, have begun to elucidate the underlying neurobiological bases of social conformity. Neuroimaging studies show that brain areas, such as medial prefrontal cortex, striatum, orbitofrontal cortex, insula, amygdala, and hippocampus, play key roles in social conformity and cognitive imbalance. Evidences from the molecular genetic studies show that some genetic factors, such as the COMT gene, oxytocin, and Methylphenidate can enhance reward saliency by increasing dopamine in the brain, thus indirectly modulating social conformity. These reward-based reinforcement-learning mechanisms can explain social conformity. Future studies need to adapt an experimental paradigm to include more diverse populations, such as adolescents and elderly samples as well as patients with various psychopathology and brain lesions. It would also be promising to integrate different methodologies to clarify the neurobiological basis of social conformity.
