Abstract

Social comparison orientation (SCO) refers to the tendency to compare oneself with others and has two distinct dimensions: one about opinions and the other about abilities. Although dissociable neural mechanisms underlying the two dimensions of social comparison can be assumed, little is known about how each dimension of SCO is associated with cognitive and brain health among older adults. To investigate this, we analyzed the SCO scale questionnaire data, neuropsychological assessment data, and multimodal MRI data collected from 90 community-dwelling older adults. We found that global cognitive performance was positively correlated with the score of the opinion subscale but not with the score of the ability subscale and the total score. Similarly, hippocampal volume was positively correlated with opinion score alone. Additionally, the resting-state functional connectivity between the hippocampal seed and the default mode network showed a positive correlation only with the opinion score. Moreover, fractional anisotropy in the hippocampal cingulum was positively correlated with opinion score only. These findings suggest that global cognition and hippocampal properties in older age are associated with the SCO of opinion, which could reflect a regular habit of performing the types of cognitively demanding activities involved in evaluation of self and other opinions.

老年人社会比较取向与海马特性之间的关系:一项多模态MRI研究。

社会比较倾向(Social comparison orientation, SCO)是指一种将自己与他人进行比较的倾向，它有两个不同的维度:一个是观点取向，另一个是能力取向。虽然可以假设社会比较的两个维度背后可分离的神经机制，但对于SCO的每个维度如何与老年人的认知和大脑健康相关联，我们知之甚少。为了研究这一点，我们分析了来自90名社区居住老年人的SCO量表问卷数据、神经心理学评估数据和多模态MRI数据。我们发现，整体认知表现与意见分量表得分呈正相关，而与能力分量表得分和总分无显著正相关。同样，海马体积与意见得分正相关。此外，海马体种子和默认模式网络之间的静息状态功能连接仅与意见得分呈正相关。此外，海马扣带的分数各向异性仅与意见评分呈正相关。这些发现表明，老年人的全球认知和海马体特性与意见SCO有关，这可能反映了一种常规的习惯，即进行涉及评估自我和他人意见的认知要求活动。

期刊介绍： Social Neuroscience features original empirical Research Papers as well as targeted Reviews, Commentaries and Fast Track Brief Reports that examine how the brain mediates social behavior, social cognition, social interactions and relationships, group social dynamics, and related topics that deal with social/interpersonal psychology and neurobiology. Multi-paper symposia and special topic issues are organized and presented regularly as well. The goal of Social Neuroscience is to provide a place to publish empirical articles that intend to further our understanding of the neural mechanisms contributing to the development and maintenance of social behaviors, or to understanding how these mechanisms are disrupted in clinical disorders.
