接受社会反馈，如对一个人性格特征的赞扬或指责，是日常人际交往的一个关键组成部分。有人提出，人类在将社会反馈整合到自我概念中时会产生积极的偏见。然而，缺乏对人类如何处理自我相关反馈的机械描述。在这里，参与者在现实生活中的互动后收到了同龄人的反馈。参与者以积极的偏见方式处理反馈，即，他们改变了他们的自我评价更倾向于可取的，而不是不可取的反馈。使用功能磁共振成像，我们调查了两个反馈组件。首先，奖励相关成分与腹侧纹状体和前扣带皮层/内侧前额叶皮层（ACC/MPFC）的活动相关。第二，比较相关成分与心智化网络中的活动相关，包括MPFC、颞顶连接、上级颞沟、颞极和额下回。心理化系统中的这种与比较相关的活动有一种简约的解释，即，活动与参与者自己的评价和反馈之间的差异相关。重要的是，活动内的MPFC，集成奖励相关和比较相关的组件预测的自我相关的积极更新偏见的参与者提供一个机械帐户的积极偏见的反馈处理。因此，奖励和心智化理论对于更好地理解社会信息如何融入人类自我概念非常重要。
Receiving social feedback such as praise or blame for one's character traits is a key component of everyday human interactions. It has been proposed that humans are positively biased when integrating social feedback into their self-concept. However, a mechanistic description of how humans process self-relevant feedback is lacking. Here, participants received feedback from peers after a real-life interaction. Participants processed feedback in a positively biased way, i.e., they changed their self-evaluations more toward desirable than toward undesirable feedback. Using functional magnetic resonance imaging we investigated two feedback components. First, the reward-related component correlated with activity in ventral striatum and in anterior cingulate cortex/medial prefrontal cortex (ACC/MPFC). Second, the comparison-related component correlated with activity in the mentalizing network, including the MPFC, the temporoparietal junction, the superior temporal sulcus, the temporal pole, and the inferior frontal gyrus. This comparison-related activity within the mentalizing system has a parsimonious interpretation, i.e., activity correlated with the differences between participants' own evaluation and feedback. Importantly, activity within the MPFC that integrated reward-related and comparison-related components predicted the self-related positive updating bias across participants offering a mechanistic account of positively biased feedback processing. Thus, theories on both reward and mentalizing are important for a better understanding of how social information is integrated into the human self-concept.
