Relational Models Theory or RMT proposes that there are four universal ways in which socio-economic relations can be organized. According to the RMT, each of its four relational models (Communal Sharing, Authority Ranking, Equality Matching, and Market Pricing) is associated with a distinct cognitive representation, with a cumulative pattern in which each relational model is a superset of the next lower model. This report for the first time uses a combination of cognitive and the social neuroscience to put this model to the test. RMT proposes that members of every culture use all four relational models, just in different proportions. It should therefore be possible to study their neural correlates in a mono-cultural sample. In this study, thirty-nine European-American students were imaged in a 3T Siemens Trio with a 24-channel head coil while rating the extent to which each relational model organized relationships with each of thirty-two acquaintances/friend/relatives in a boxcar design. FreeSurfer Functional Analysis Stream (FS-FAST) analyses revealed distinct patterns of activation for each of the relational models. The activations did not follow a cumulative hierarchical pattern, suggestive that this aspect of the RMT model should be revised.
关系模型理论（RMT）提出，社会经济关系有四种普遍的组织方式。根据RMT，其四个关系模型（共同分享、权威排序、平等匹配和市场定价）中的每一个都与一种独特的认知表征相关联，呈现出一种累积模式，即每个关系模型都是下一个较低模型的超集。本报告首次结合认知科学和社会神经科学对该模型进行检验。RMT提出，每种文化的成员都会使用所有四种关系模型，只是比例不同。因此，应该能够在单一文化样本中研究它们的神经关联。在这项研究中，39名欧美学生在配备24通道头部线圈的3T西门子Trio磁共振成像仪上接受扫描，同时以盒式设计对每种关系模型在组织与32名熟人/朋友/亲戚的关系中的程度进行评分。FreeSurfer功能分析流程（FS - FAST）分析揭示了每个关系模型独特的激活模式。这些激活模式并未遵循累积层次模式，这表明RMT模型的这一方面应该进行修正。
