Insight Into

In groups, individuals often adjust their behavior to the majority’s. Here, we provide a brief introduction into the research on social conformity and review the first, very recent investigations elucidating the underlying neurocognitive mechanisms. Multiple studies suggest that conformity is a behavioral adjustment based on reinforcement-learning mechanisms in posterior medial frontal cortex and ventral striatum. It has also been suggested that the detection of cognitive inconsistency and the modulation of basic encoding processes are involved. Together, recent findings provide valuable insight into the neural and cognitive mechanisms underlying social conformity and clearly point up the need for further studies in this field.

To elucidate the neural mechanisms underlying the development of perceptual expertise, we recorded ERPs while participants performed a categorization task. We found that as participants learned to discriminate computer generated “blob” stimuli, feedback modulated the amplitude of the error-related negativity (ERN)—an ERP component thought to reflect error evaluation within medial–frontal cortex. As participants improved at the categorization task, we also observed an increase in amplitude of an ERP component associated with object recognition (the N250). The increase in N250 amplitude preceded an increase in amplitude of an ERN component associated with internal error evaluation (the response ERN). Importantly, these electroencephalographic changes were not observed for participants who failed to improve on the categorization task. Our results suggest that the acquisition of perceptual expertise relies on interactions between the posterior perceptual system and the reinforcement learning system involving medial–frontal cortex.
