人们每天都依赖第一印象作为解释社会行为的重要工具。虽然研究开始揭示第一印象的神经基础，特别是通过了解背内侧前额叶皮层 (dmPFC) 的作用，但人们对第一印象编码到记忆中的方式知之甚少。这是令人惊讶的，因为从社会角度来看，第一印象与未来的互动相关，需要将它们转移到记忆中。本研究使用后续记忆范式来测试 dmPFC 参与第一印象编码的条件。我们发现，有意形成印象比无意形成印象更能吸引 dmPFC，而且这种参与支持记忆印象的编码。此外，我们发现诊断信息更容易形成特质印象，比中性信息更能吸引 dmPFC。这些结果表明，促进印象记忆的神经系统对有意识形成的印象很敏感。研究结果还表明，社会记忆系统与由内侧颞叶控制的其他外显记忆系统之间存在区别。
People rely on first impressions every day as an important tool to interpret social behavior. While research is beginning to reveal the neural underpinnings of first impressions, particularly through understanding the role of dorsal medial prefrontal cortex (dmPFC), little is known about the way in which first impressions are encoded into memory. This is surprising because first impressions are relevant from a social perspective for future interactions, requiring that they be transferred to memory. The present study used a subsequent-memory paradigm to test the conditions under which the dmPFC is implicated in the encoding of first impressions. We found that intentionally forming impressions engages the dmPFC more than does incidentally forming impressions, and that this engagement supports the encoding of remembered impressions. In addition, we found that diagnostic information, which more readily lends itself to forming trait impressions, engages the dmPFC more than does neutral information. These results indicate that the neural system subserving memory for impressions is sensitive to consciously formed impressions. The results also suggest a distinction between a social memory system and other explicit memory systems governed by the medial temporal lobes.
