社会比较取向是指将自己与他人进行比较的倾向，它有两个不同的维度：一个是关于观点，另一个是关于能力。虽然可以假设社交比较的两个维度背后存在分离的神经机制，但关于SCO的每个维度如何与老年人的认知和大脑健康相关的信息知之甚少。为了研究这一点，我们分析了来自90名社区老年人的SCO量表问卷数据、神经心理学评估数据和多模式MRI数据。研究发现，总体认知成绩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相关。同样，仅海马体体积与意见得分呈正相关。此外，海马区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，海马扣带各向异性分数仅与意见得分呈正相关。这些发现表明，老年人的整体认知和海马区特性与观点的SCO有关，这可能反映了一种常规的习惯，即执行与评估自我和其他观点有关的认知要求活动类型。
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.
