Pro-social behaviors are voluntary behaviors that benefit other people or society as a whole, such as charitable donations, cooperation, trust, altruistic punishment, and fairness. These behaviors have been widely described through non self-interest decision-making in behavioral experimental studies and are thought to be increased by social preference motives. Importantly, recent studies using a combination of neuroimaging and brain stimulation, designed to reveal the neural mechanisms of pro-social behaviors, have found that a wide range of brain areas, specifically the prefrontal cortex, (...) anterior insula, anterior cingulate cortex, and amygdala, are correlated or causally related with pro-social behaviors. In this review, we summarize the research on the neural basis of various kinds of pro-social behaviors and describe a common shared neural circuitry of these pro-social behaviors. We introduce several general ways in which experimental economics and neuroscience can be combined to develop important contributions to understanding social decision-making and pro-social behaviors. Future research should attempt to explore the neural circuitry between the frontal lobes and deeper brain areas. (shrink)

Trends in moral psychology largely support the role that emotion plays in moral cognition with human lesion studies offering the most compelling evidence to date. Specifically, data from ventromedial prefrontal cortex (vmPFC) patients on moral judgment tasks has suggested the necessity of having intact emotion to behave in morally appropriate ways. However, patients with vmPFC damage also have deficits in a variety of complex judgment and decision-making tasks, regardless of whether emotion is involved. This paper argues that a basic information (...) processing perspective of vmPFC functionality is a better interpretation of vmPFC patient deficits, specifically with the vmPFC being necessary for value assessment rather than being specific to emotion.
