in social behaviour). The ventral striatum tracked prediction errors in both the Diaconescu et al., (2017) and the Lockwood et al., (2016), but in a way that is suggestive of a domain-general response to learning about the unexpectedness of outcomes. For example, Lockwood et al., (2016) had a ‘no-one’ condition where points were delivered but participants were told they would not be converted into money either for themselves or another person. Whereas ventral striatum tracked outcomes during self, prosocial and no one learning, sgACC specifically responded in the prosocial condition only. The OFC has also been linked to social cognition (Jones et al., 2011; Rushworth et al., 2007) but again seems more domain general than the sgACC. For example, Chang and colleagues (2013) recorded from OFC neurons in a reward-allocation task in macaques and found that these neurons predominantly responded to rewards delivered to oneself and not to others or no one. These findings support the idea that sgACC is relatively domain specific for social processing in certain contexts, but this hypothesis would need to be tested in further studies.
