在过去的十年里，创造力已经成为神经认知研究的焦点。然而，大脑区域的异质模式被认为是创造力的神经相关因素的基础。对这些不同发现的一种解释是，人们通常不会根据创造力的许多潜在认知过程来研究创造力。目前的功能磁共振成像研究重点关注概念扩展的神经关联，概念扩展是所有创造性过程的核心组成部分。该研究旨在通过采用一种新颖的范式来避免之前关于创造力的功能磁共振成像研究的陷阱。参与者被呈现短语并就刺激的异常性和适当性做出判断，这与创造力的两个定义标准相对应。根据他们各自的评价，得到了三个受试者确定的实验条件。被认为既不寻常又合适的短语被归类为表明参与者概念扩展。研究结果揭示了在进行被动概念扩展时额叶和颞叶区域的参与，而不是仅仅处理异常性（新颖性）或适当性（相关性）的信息。采用这种新的实验方法来揭示创造性认知中涉及的特定过程，揭示了已知参与语义认知和关系推理的额叶和颞叶区域在被动概念扩展中发挥着作用。在创造力研究中采用不同的有利角度将使该主题的未来研究取得关键进展。
Creativity has emerged in the focus of neurocognitive research in the past decade. However, a heterogeneous pattern of brain areas has been implicated as underpinning the neural correlates of creativity. One explanation for these divergent findings lies in the fact that creativity is not usually investigated in terms of its many underlying cognitive processes. The present fMRI study focuses on the neural correlates of conceptual expansion, a central component of all creative processes. The study aims to avoid pitfalls of previous fMRI studies on creativity by employing a novel paradigm. Participants were presented with phrases and made judgments regarding both the unusualness and the appropriateness of the stimuli, corresponding to the two defining criteria of creativity. According to their respective evaluation, three subject-determined experimental conditions were obtained. Phrases judged as both unusual and appropriate were classified as indicating conceptual expansion in participants. The findings reveal the involvement of frontal and temporal regions when engaging in passive conceptual expansion as opposed to the information processing of mere unusualness (novelty) or appropriateness (relevance). Taking this new experimental approach to uncover specific processes involved in creative cognition revealed that frontal and temporal regions known to be involved in semantic cognition and relational reasoning play a role in passive conceptual expansion. Adopting a different vantage point on the investigation of creativity would allow for critical advances in future research on this topic.
