项目摘要

Our reputation is important to us; we feel good when we find out that people think highly of us, and we feel bad when we find out that people think poorly of us. Behavioral research has demonstrated that reputation can be considered as a commodity, similar to goods or money, in that people will take action to obtain gains or avoid losses in reputation. Importantly however, the way in which the human brain processes social feedback regarding one's reputation is currently unclear. Is reputation processed like other non-social commodities, or in a unique way, with neural substrates reserved just for social phenomena? With this in mind, we propose to investigate three aspects of how humans process gains and losses in reputation, and relate this to the better-understood processing of non-social monetary reward and loss. We first aim to characterize the neural underpinnings of processing gains and losses in reputation. Second, we will investigate the role of the neurotransmitter dopamine in reputation processing. Last, we will examine whether gains or losses in reputation can be explained within the "prediction error" framework from reinforcement learning theory. If our hypotheses are correct, our results will elucidate the processing of social feedback at the neural and behavioral levels, and will demonstrate similarities and differences with the processing of non-social monetary rewards and losses.

我们的声誉对我们很重要；当我们发现人们对我们评价很高时，我们感觉很好；当我们发现人们对我们评价不好时，我们感觉很糟糕。行为研究表明，声誉可以被视为一种商品，类似于商品或金钱，人们会采取行动来获得声誉的收益或避免声誉的损失。然而重要的是，人类大脑处理有关个人声誉的社会反馈的方式目前尚不清楚。声誉是否像其他非社会商品一样被处理，或者以一种独特的方式，只为社会现象保留神经基质？考虑到这一点，我们建议研究人类如何处理声誉得失的三个方面，并将其与更好地理解的非社会金钱奖励和损失的处理联系起来。我们首先旨在描述处理声誉得失的神经基础。其次，我们将研究神经递质多巴胺在声誉处理中的作用。最后，我们将研究是否可以在强化学习理论的“预测误差”框架内解释声誉的获得或损失。如果我们的假设是正确的，我们的结果将阐明神经和行为层面的社会反馈处理，并将展示与非社会金钱奖励和损失处理的异同。
