Cerebral activations involved in actual writing of a new story and the associated correlates with creative performance are still unexplored. To investigate the different aspects of the creative writing process, we used functional magnetic resonance imaging while 28 healthy participants performed a new paradigm related to creative writing: "brainstorming" (planning a story) and "creative writing" (writing a new and creative continuation of a given literary text), as well as an additional control paradigm of "reading" and "copying." Individual verbal creativity was assessed with a verbal creativity test and creative performance with a qualitative rating of the creative products. "brainstorming" engaged cognitive, linguistic, and creative brain functions mainly represented in a parieto-frontal-temporal network, as well as writing preparation, and visual and imaginative processing. "creative writing" activated motor and visual brain areas for handwriting and additionally, cognitive and linguistic areas. Episodic memory retrieval, free-associative and spontaneous cognition, and semantic integration were observed in a right lateralized activation pattern in bilateral hippocampi, bilateral temporal poles (BA 38), and bilateral posterior cingulate cortex in a "creative writing" minus "copying" comparison. A correlation analysis of "creative writing" minus "copying" with the creativity index revealed activation in the left inferior frontal gyrus (BA 45) and the left temporal pole (BA 38). Thus, verbal creativity during "creative writing" is associated with verbal and semantic memory as well as semantic integration.
目前,有关实际创作新故事时大脑的激活情况,以及与创造力表现相关的情况,仍有待进一步探索。为了研究创造性写作过程的不同方面,我们使用功能磁共振成像技术,让 28 名健康参与者参与一个与创造性写作相关的新范式:“头脑风暴”(规划故事)和“创造性写作”(根据给定的文学文本创作一个新的有创意的续写),以及一个额外的控制范式“阅读”和“复制”。个体的言语创造力通过言语创造力测试进行评估,而创造性表现则通过对创造性产品的定性评价进行评估。“头脑风暴”主要涉及认知、语言和创造性的大脑功能,主要表现在顶叶-额-颞叶网络中,同时还涉及写作准备、视觉和想象加工。“创造性写作”激活了与手写相关的运动和视觉大脑区域,此外还激活了认知和语言区域。在“创造性写作”减去“复制”的比较中,观察到右侧海马体、双侧颞极(BA 38)和双侧后扣带回的右侧偏侧化激活模式中的情节记忆检索、自由联想和自发认知以及语义整合。“创造性写作”减去“复制”与创造力指数的相关分析显示,左侧额下回(BA 45)和左侧颞极(BA 38)有激活。因此,“创造性写作”过程中的言语创造力与言语和语义记忆以及语义整合有关。
