Person perception is a dynamic, evolving process. Because other people are an endless source of social information, people need to update their impressions of others based upon new information. We devised an fMRI study to identify brain regions involved in updating impressions. Participants saw faces paired with valenced behavioral information and were asked to form impressions of these individuals. Each face was seen five times in a row, each time with a different behavioral description. Critically, for half of the faces the behaviors were evaluatively consistent, while for the other half they were inconsistent. In line with prior work, dorsomedial prefrontal cortex (dmPFC) was associated with forming impressions of individuals based on behavioral information. More importantly, a whole-brain analysis revealed a network of other regions associated with updating impressions of individuals who exhibited evaluatively inconsistent behaviors, including rostrolateral PFC, superior temporal sulcus, right inferior parietal lobule and posterior cingulate cortex.
人际感知是一个动态、不断发展的过程。由于他人是无穷无尽的社交信息来源，人们需要根据新信息更新对他人的印象。我们设计了一项 fMRI 研究来确定参与印象更新的大脑区域。参与者看到与情绪性行为信息配对的面孔，并被要求对这些个体形成印象。每个面孔连续出现五次，每次都有不同的行为描述。关键是，对于一半的面孔，行为是评价一致的，而对于另一半，行为是不一致的。与先前的研究一致，背内侧前额叶皮层（dmPFC）与根据行为信息形成对个体的印象有关。更重要的是，全脑分析显示了一个与更新表现出评价不一致行为的个体印象相关的其他区域网络，包括额下回外侧部、颞上回、右顶下小叶和后扣带皮层。
