公平是社会互动中的一个关键概念，并受到意向性考虑的影响。在这项功能性磁共振成像研究中，我们研究了公平性的神经相关性，重点是在最后通牒博弈范式中对不公平报价的反应行为，其条件不同，其意图性约束。拒绝与接受不公平的提议的大脑活动似乎高度依赖于意向性。当提议者没有选择时拒绝不公平的提议，以及当提议者有一个公平或超公平的选择时接受提议，都与包括大脑皮层和背内侧前额叶皮层在内的区域网络的激活有关。这些激活被解释为对规范违反的神经反应，因为它们主要涉及行为与社会接受的行为模式不一致。在没有选择的情况下，拒绝不公平的提议进一步导致前内侧前额叶皮层和颞顶联合区的活动，这被解释为当拒绝不容易被证明时，社会决策需要更高的道德心理化要求。总之，结果突出了公平相关的社会决策过程中的意向性考虑的重要性。
Fairness is a key concept in social interactions and is influenced by intentionality considerations. In this functional magnetic resonance imaging study, we investigated the neural correlates of fairness by focusing on responder behavior to unfair offers in an Ultimatum Game paradigm with conditions that differed in their intentionality constraints. Brain activity underlying rejection vs acceptance of unfair offers appeared highly dependent on intentionality. Rejection of unfair offers when the proposer had no-alternative as well as acceptance of offers when the proposer had a fair- or hyperfair-alternative was associated with activation in a network of regions including the insula and the dorsal medial prefrontal cortex. These activations were interpreted as neural responses to norm violations because they were mostly involved when behavior was inconsistent with socially accepted behavior patterns. Rejection of unfair offers in the no-alternative condition further resulted in activity in the anterior medial prefrontal cortex and the temporoparietal junction, which was interpreted in terms of higher moral mentalizing demands required in social decision-making when rejection could not be readily justified. Together, results highlight the significance of intentionality considerations in fairness-related social decision-making processes.
