Neurotechnology has been applied to gain insights on creativity-related cognitive factors. Prior research has identified relations between cognitive factors and creativity qualitatively; while quantitative relations, such as the relative importance of cognitive factors and creativity, have not been fully determined. Therefore, taking the creative design process as an example, this study using electroencephalography (EEG) aims to objectively identify how creativity-related cognitive factors of retrieval, recall, association, and combination contribute to creativity. The theoretical basis for an EEG-based decoding method to objectively identify which cognitive factors occur in a creative process is developed. Thirty participants were recruited for a practical study to verify the reliability of the decoding method. Based on the methodology, relationships between the relative importance level of the cognitive factor and creative output quality levels were detected. Results indicated that the occurrence of recall and association are reported with a high reliability level by the decoding method. The results also indicated that association is the dominant cognitive factor for higher creative output quality levels. Recall is the dominant cognitive factor for lower creative output quality levels.

一种基于脑电图的方法来解码创作过程中的认知因素

神经技术已被应用于深入了解与创造力相关的认知因素。先前的研究已经定性地确定了认知因素与创造力之间的关系；而定量关系，如认知因素和创造力的相对重要性，尚未完全确定。因此，以创意设计过程为例，本研究使用脑电图 (EEG) 旨在客观地确定与创造力相关的检索、回忆、联想和组合等认知因素如何促进创造力。开发了基于脑电图的解码方法客观识别创作过程中出现哪些认知因素的理论基础。招募了 30 名参与者进行实际研究，以验证解码方法的可靠性。基于该方法，检测了认知因素的相对重要性水平与创造性输出质量水平之间的关系。结果表明，解码方法以高可靠性水平报告了回忆和联想的发生。结果还表明，联想是更高创意输出质量水平的主要认知因素。召回是较低创意输出质量水平的主要认知因素。
