Abstract

The comparative study of three different models of creative thinking in unified event-related (ERP) paradigm is presented. The subjects (18–35 years old) performed the following tasks: PROVERBS (a divergent creative task to overcome stereotypes of long-term memory), REMOTE ASSOCIATIONS (a convergent creative task activating remote semantic fields), ALTERNATIVE USES TASK (a divergent creative task with the initiation of the associative search process). In the creative tasks, subjects required to create an original ending to a proverb (Pr), find a word that could be matched with three presented words from different semantic fields (RAT), invent original ways of using common objects (AUT). In the control tasks subjects were required to recall a well-known ending to a proverb (PrM), and to list/name objects from a given category (CAT). The ERP amplitudes were analyzed when comparing the tasks with each other. Greater negativity was observed for the a component with around 300 ms latency (~N300) in frontal regions (280–346 ms after stimuli onset) in the Pr task, which probably reflects inhibition of the patterns of long-term memory. In the Pr and RAT tasks, semantic retrieval and integration of new information versus retrieval of known information from memory (PrM) was characterized by lower amplitude values of late components at the 698–786 ms interval. The greater amplitude of late ERP components in parietal regions (524–624 ms) during divergent thinking (AUT) may correspond to the greater emergence of images in this task compared to more abstract RAT and Pr tasks. Thus, even in the early stages of information processing in verbal creative tasks performance, the specificity of different models of creative thinking appears in the same temporal paradigm and similar visual stimuli presentation.

不同语言创造性思维模式中的事件相关电位特征

摘要本文介绍了在统一事件相关（ERP）范式下对三种不同的创造性思维模型进行的比较研究。被试（18-35 岁）完成了以下任务：PROVERBS（一项发散性创造性任务，旨在克服对长期记忆的刻板印象）、REMOTE ASSOCIATIONS（一项聚合性创造性任务，旨在激活远程语义场）、ALTERNATIVE USES TASK（一项发散性创造性任务，旨在启动联想搜索过程）。在创造性任务中，受试者需要为一句谚语创造一个新颖的结尾（Pr），找到一个可以与来自不同语义场的三个呈现词匹配的词（RAT），发明使用常见物品的新方法（AUT）。在对照任务中，受试者需要回忆谚语的一个著名结尾（PrM），并列出/说出给定类别中的物体（CAT）。在对这些任务进行比较时，对 ERP 振幅进行了分析。在Pr任务中，在前额区（刺激开始后280-346毫秒）观察到潜伏期约为300毫秒（~N300）的成分具有更大的负性，这可能反映了对长期记忆模式的抑制。在 Pr 和 RAT 任务中，语义检索和整合新信息与检索记忆中的已知信息（PrM）相比，晚期成分在 698-786 毫秒间隔内的振幅值较低。在发散思维（AUT）任务中，顶叶区的ERP晚期成分（524-624 ms）振幅较大，这可能与该任务中出现的图像比更抽象的RAT和Pr任务更多有关。因此，即使在口头创造性任务表现的早期信息处理阶段，在相同的时间范式和类似的视觉刺激呈现中，也会出现不同创造性思维模式的特异性。
