单一系统或分离系统处理社会规范的程度仍然存在争议。许多关于儿童社会认知判断的研究都支持“道德”（基于伤害/福利）和“传统”规范之间的区别。然而，可分离神经系统处理这些规范的程度仍不清楚。为了解决这个问题，我们对 23 名健康参与者进行了功能性磁共振成像 (fMRI) 扫描，同时他们对基于伤害/福利、传统越轨和中性小插图的错误进行了评级。在评估基于伤害/福利和社会传统的越轨行为时，在涉及决策区域的区域（包括头侧/腹侧内侧额叶、前岛叶和背内侧额叶皮质）中观察到激活显着大于中性晕影基线。当相对于社会传统的越轨行为进行基于伤害/福利的评估时，在 ACC 和双侧额下回的大部分区域可以看到更大的激活。当评估相对于基于伤害/福利的越轨行为时，在颞上回、双侧颞中回、左侧 PCC 和颞顶叶交界处观察到更大的激活。这些数据表明，有关行为错误的决策，无论是否涉及基于护理/伤害的违规行为或传统的违规行为，都会招募区域通常涉及基于情感的决策。然而，基于护理/伤害的越轨行为和传统的越轨行为之间存在神经差异。这可能反映了处理传统规范违规者意图的特别重要性，并且可能反映了基于护理/伤害的违规行为的更大的情感内容或显着性。
The degree to which social norms are processed by a unitary system or dissociable systems remains debated. Much research on children’s social-cognitive judgments has supported the distinction between “moral” (harm/welfare-based) and “conventional” norms. However, the extent to which these norms are processed by dissociable neural systems remains unclear. To address this issue, 23 healthy participants were scanned with functional magnetic resonance imaging (fMRI) while they rated the wrongness of harm/welfare-based and conventional transgression and neutral vignettes. Activation significantly greater than the neutral vignette baseline was observed in regions implicated in decision-making regions including rostral/ventral medial frontal, anterior insula and dorsomedial frontal cortices when evaluating both harm/welfare-based and social conventional transgressions. Greater activation when rating harm/welfare-based relative to social-conventional transgressions was seen through much of ACC and bilateral inferior frontal gyrus. Greater activation was observed in superior temporal gyrus, bilateral middle temporal gyrus, left PCC, and temporal-parietal junction when rating social-conventional transgressions relative to harm/welfare-based transgressions. These data suggest that decisions regarding the wrongness of actions, irrespective of whether they involve care/harm-based or conventional transgressions, recruit regions generally implicated in affect-based decision-making. However, there is neural differentiation between care/harm based and conventional transgressions. This may reflect the particular importance of processing the intent of transgressors of conventional norms and perhaps the greater emotional content or salience of care/harm based transgressions.
