The ability to accurately infer one's place with respect to others is crucial for social interactions. Individuals tend to evaluate their own actions and outcomes by comparing themselves to others in either an upward or downward direction. We performed two fMRI meta-analyses on monetary (n = 39; 1,231 participants) and status (n = 23; 572 participants) social comparisons to examine how domain and the direction of comparison can modulate neural correlates of social hierarchy. Overall, both status and monetary downward comparisons activated regions associated with reward processing (striatum) while upward comparisons yielded loss-related activity. These findings provide partial support for the common currency hypothesis in that downward and upward comparisons from both monetary and status domains resemble gains and losses, respectively. Furthermore, status upward and monetary downward comparisons revealed concordant orbitofrontal cortical activity, an area associated with evaluating the value of goals and decisions implicated in both lesion and empirical fMRI studies investigating social hierarchy. These findings may offer new insight into how people relate to individuals with higher social status and how these social comparisons deviate across monetary and social status domains.
准确推断自己相对于他人的位置对于社交互动至关重要。个体倾向于通过向上或向下与他人比较来评估自己的行为和结果。我们对货币(n=39;1231 名参与者)和地位(n=23;572 名参与者)的社会比较进行了两次 fMRI 荟萃分析,以研究领域和比较方向如何调节社会等级的神经关联。总的来说,地位和货币的向下比较都会激活与奖励处理相关的区域(纹状体),而向上比较则会产生与损失相关的活动。这些发现为共同货币假说提供了部分支持,因为来自货币和地位领域的向下和向上比较分别类似于收益和损失。此外,地位向上和货币向下的比较揭示了眶额皮质活动的一致性,该区域与评估目标和决策的价值有关,这些目标和决策涉及到研究社会等级的损伤和实证 fMRI 研究。这些发现可能为人们如何与社会地位较高的个体建立联系以及这些社会比较如何在货币和社会地位领域中偏离提供新的见解。
