Effects of Visual Analogy in Design Task on Brain Functional Connectivity Related to Creative Thinking

Abstract

Visual analogies are considered effective in design. In this study, we conducted a design task under three conditions: (i) no analogy, (ii) within-domain analogy, and (iii) between-domain analogy. We then analyzed functional connectivity (FC) of electroencephalography (EEG) data and compared the results with creativity scores. The analysis focused on the default mode network (DMN), the executive control network (ECN) and the salience network (SN), which are thought to be related to creativity. The results suggested that a weak correlation was observed between changes in FC between the posterior cingulate cortex (PCC) and the left inferior parietal lobule (l-IPL) and creativity scores.
