摘要

在实践中,个人会努力在特定的限制条件下开发具有高度原创性和价值的创意产品。然而,以往的功能磁共振成像(fMRI)研究侧重于发散思维任务,而没有考虑创意的 "价值"。此外,不同类型的创意任务(如较容易的联想任务与较难的联想任务)可能涉及不同的认知过程。本研究旨在探究与不同类型的创造性思维相关的潜在神经机制,特别是在 fMRI 扫描仪中生成最具原创性和价值的创造性产品。21 名大学生参加了一项分块设计研究。在每次试验中,参与者都被要求从给定的图形中获得灵感,绘制出最具独创性和价值的产品。研究结果显示,与较难的联想任务相比,较容易的联想任务会导致多个大脑区域更广泛的激活。然而,这种更广泛的激活导致思维效率低下,创造性表现较差。值得注意的是,眶额皮层在各种创造性任务中都表现出激活,并显示出与多个种子脑区的连接,这突出了在只允许一个原创和有价值的产品设计时决策的重要性。此外,在不同大脑网络之间观察到的复杂功能连接反映了创造性思维的复杂性。总之,大脑区域的广泛激活并不一定代表着卓越的创造力。相反,通过有效利用联想产生创新想法、抑制非原创想法以及决策选择最具创意的想法,才能在限制条件下实现最佳的创造性表现。

Investigating the neural substrate variations between easy and challenging creative association tasks during product design within an fMRI scanner

In practice, individuals strive to develop highly original and valuable creative products within specific limitations. However, previous functional Magnetic Resonance Imaging (fMRI) studies focused on divergent-thinking tasks without considering the "valuableness" of an idea. Additionally, different types of creative tasks (e.g., the easier association vs. the harder association task) may engage distinct cognitive processes. This study aimed to investigate the underlying neural mechanisms associated with different types of creative thinking, specifically focusing on the generation of the most original and valuable creative product within an fMRI scanner. Twenty-one college students participated in a block design study. During each trial, participants were instructed to draw the most original and valuable product inspired by a given figure. The findings revealed that, in comparison to the harder association task, the easier association task led to broader activation across multiple brain regions. However, this broader activation resulted in inefficient thinking and poorer creative performance. Notably, the orbitofrontal cortex exhibited activation across various creativity tasks and displayed connectivity with several seed brain regions, highlighting the importance of decision-making when only one original and valuable product design is allowed. Furthermore, the complex functional connectivity observed between different brain networks reflects the intricate nature of creative thinking. To conclude, widespread activation of brain regions does not necessarily indicate superior creativity. Instead, optimal creative performance within constraints is achieved through an efficient utilization of association for generating innovative ideas, inhibition for suppressing unoriginal ideas, and decision-making to select the most creative idea.
