创造性思维依赖于现有知识的重组，以产生新颖和有用的概念。然而，这些新概念是如何形成的，特别是通过新奇和有用性（通常被认为是创造性的关键属性）的加工过程，目前还不清楚。以熟悉和有用（FU）的对象/设计为起点或基本基线，我们将它们修改为新颖和无用（NS）的对象/设计或新颖和有用（NU）的对象/设计（即，真正有创造力的人）来研究新奇和有用性的特征是如何加工的（新奇加工：NU减FU;有用性加工：NU减NS）。具体来说，我们预测，创造性的整合新奇和实用性不仅需要形成新的协会，这可能是关键介导的海马和相邻的内侧颞叶（MTL）地区，但也形成新的概念或类别，这是支持中颞回（MTG）。我们发现，MTL和MTG都参与了新奇和有用性的加工。MTG表现出独特的信息处理模式，反映在与海马的功能连接加强以构建新概念，以及与执行控制系统的功能连接加强以打破旧概念的界限。此外，被试对概念距离的主观评价表明，熟悉概念（FU）与成功构建的概念（NU）之间的距离大于FU与未成功构建的概念（NS）之间的距离，并且发现这种模式与MTG中的神经表征模式相对应。这些研究结果表明，新的协会和概念的形成过程中的新奇性和有用性的创造性设计的关键机制，这种机制可能是关键介导的校园MTG连接。
Creative thought relies on the reorganization of existing knowledge to generate novel and useful concepts. However, how these new concepts are formed, especially through the processing of novelty and usefulness (which are usually regarded as the key properties of creativity), is not clear. Taking familiar and useful (FU) objects/designs as the starting point or fundamental baseline, we modified them into novel and useless (NS) objects/designs or novel and useful (NU) ones (i.e., truly creative ones) to investigate how the features of novelty and usefulness are processed (processing of novelty: NU minus FU; processing of usefulness: NU minus NS). Specifically, we predicted that the creative integration of novelty and usefulness entails not only the formation of new associations, which could be critically mediated by the hippocampus and adjacent medial temporal lobe (MTL) areas, but also the formation of new concepts or categories, which is supported by the middle temporal gyrus (MTG). We found that both the MTL and the MTG were involved in the processing of novelty and usefulness. The MTG showed distinctive patterns of information processing, reflected by strengthened functional connectivity with the hippocampus to construct new concepts and strengthened functional connectivity with the executive control system to break the boundaries of old concepts. Additionally, participants’ subjective evaluations of concept distance showed that the distance between the familiar concept (FU) and the successfully constructed concept (NU) was larger than that between the FU and the unsuccessfully constructed concept (NS), and this pattern was found to correspond to the patterns of their neural representations in the MTG. These findings demonstrate the critical mechanism by which new associations and concepts are formed during novelty and usefulness processing in creative design; this mechanism may be critically mediated by the hippocampus-MTG connection.
