How do people update their impressions of close others? Although people may be motivated to maintain their positive impressions, they may also update their impressions when their expectations are violated (i.e. prediction error). Combining neuroimaging and computational modeling, we test the hypothesis that brain regions associated with theory of mind, especially right temporoparietal junction (rTPJ), underpin both motivated impression maintenance and impression updating evoked by prediction error. Participants had money either given to or taken away from them by a friend or a stranger and were then asked to rate each partner on trustworthiness and closeness across trials. Overall, participants engaged in less impression updating for friends vs strangers. Decreased rTPJ activity in response to a friend’s negative behavior (taking money) was associated with reduced negative updating and increased positive ratings of the friend. However, to the extent that participants did update their impressions (more negative ratings) of friends, this behavioral pattern was explained by greater prediction error and greater rTPJ activity. These findings suggest that rTPJ recruitment represents the integration of prediction error signals and the capacity to overcome people’s motivation to maintain positive impressions of friends in the face of conflicting evidence.

右颞顶交界处在处理跨关系背景的社会预测错误中的作用
人们如何更新对亲密他人的印象?尽管人们可能有动力保持他们的积极印象,但当他们的期望被违反(即预测错误)时,他们也可能会更新他们的印象。结合神经影像学和计算模型,我们测试了与心理理论相关的大脑区域,尤其是右颞顶联合区 (rTPJ) 的假设,支持由预测错误引起的有动机的印象维持和印象更新。参与者有朋友或陌生人给他们或从他们那里拿走的钱,然后被要求对每个合作伙伴在试验中的可信度和亲密度进行评分。总体而言,参与者从事较少的印象更新的朋友VS陌生人。响应朋友的负面行为(拿钱)而导致的 rTPJ 活动减少与朋友的负面更新减少和正面评价增加有关。然而,就参与者确实更新了他们对朋友的印象(更多负面评价)而言,这种行为模式可以通过更大的预测误差和更大的 rTPJ 活动来解释。这些发现表明,rTPJ 招募代表了预测错误信号的整合,以及克服人们在面对相互矛盾的证据时保持朋友积极印象的动机的能力。
