在本研究中，两名参与者在玩三人最后通牒游戏(UG)时同时记录脑电。关于如何在三个玩家之间分配一定数额的钱，两位参与者都收到了不同的提议。其中一个参与者没有发言权，而另一个参与者，即响应者，能够损害所有其他参与者的收益。这项研究的目的是调查被公平或不公平对待的参与者如何评估彼此的结果，以及机构在多大程度上影响对公平的关注。分析的重点是内侧额叶负波(MFN)作为主观价值分配的早期指标。在两个接受者的份额都很低的提案之后，拥有否决权的接受者表现出更强、更负面的最惠国待遇幅度，这表明响应者倾向于向两个参与者中至少一个提供相当数额的提议。虽然无能为力的玩家关心分配给应答者的金额，但与分配给应答者的不公平报价相比，公平后最惠国待遇的幅度更大。同样，对公平的担忧决定了最惠国待遇的幅度，表明无能为力的参与者表现出消极的社会偏好，反之，响应者表现出积极的社会偏好。
In the present study EEG was recorded simultaneously while two participants were playing the three-person ultimatum game (UG). Both participants received different offers from changing proposers about how to split up a certain amount of money between the three players. One of the participants had no say, whereas the other, the responder, was able to harm the payoff of all other players. The aim of the study was to investigate how the outcomes of the respective other are evaluated by participants who were treated fairly or unfairly themselves and to what extent agency influences concerns for fairness. Analyses were focused on the medial frontal negativity (MFN) as an early index for subjective value assignment. Recipients with veto-power exhibited enhanced, more negative-going, MFN amplitudes following proposals that comprised a low share for both recipients, suggesting that responders favored offers with a fair amount to at least one of the two players. Though, the powerless players cared about the amount assigned to the responder, MFN amplitudes were larger following fair compared to unfair offers assigned to the responder. Similarly, concerns for fairness which determined the amplitude of the MFN, suggested that the powerless players exhibited negative and conversely the responders, positive social preferences.
