The Dynamic Relationship of Brain Networks Across Time Windows During Product-Based Creative Thinking

Abstract

Consensus of creativity research suggests that the measurement of both originality and valuableness is necessary when designing creativity tasks. However, few studies have emphasized valuableness when exploring underlying neural substrates of creative thinking. The present study employs product-based creativity tasks that measure both originality and valuableness in an exploration of the dynamic relationship between the default mode (DMN), executive control (ECN), and salience (SN) networks through time windows. This methodology highlights relevance, or valuableness, in creativity evaluation as opposed to divergent thinking tasks solely measuring originality. The researchers identified seven brain regions belonging to the ECN, DMN, and SN as regions of interest (ROIs), as well as four representative seeds to analyze functional connectivity in 25 college student participants. Results showed that all of the identified ROIs were involved during the creative task. The insula, precuneus, and ventrolateral prefrontal cortex (vlPFC) remained active across all stages of product-based creative thinking. Moreover, the connectivity analyses revealed varied interaction patterns of DMN, ECN, and SN at different thinking stages. The integrated findings of the whole brain, ROI, and connectivity analyses suggest a trend that the DMN and SN (which relate to bottom-up thinking) attenuate as time proceeds, whereas the vlPFC (which relates to top-down thinking) gets stronger at later stages; these findings reflect the nature of our creativity tasks and decision-making of valuableness in later stages. Based on brain region activation throughout execution of the task, we propose that product-based creative process may include three stages: exploration and association, incubation and insight, and finally, evaluation and decision making. This model provides a thinking frame for further research and classroom instruction.

“…The Product‐based Figural Creativity Test (PB‐FCT) (Yeh et al, 2013; Yeh, Hsu, et al, 2019) was employed to measure the participants' creativity. The PB‐FCT included three subtests (with figures of C, ⊓ or ⤬ in each subtest) in which participants were instructed to draw as many original and functional products as they could be based on the given figures (see Figure 2 for examples of student performance).…”

Effects of Transcranial Direct Current Stimulation on Brain Networks Related to Creative Thinking

“…Previous studies have revealed that creativity is a complex construct that requires the involvement of various brain functions such as memory, future simulation, semantic processing, and attention. Besides, recent neuroimaging studies of creativity have suggested the involvement of multiple brain networks, including the following: the default mode network (DN), the executive control network (ECN), and the salience network (SN) (Beaty et al, 2016(Beaty et al, , 2017(Beaty et al, , 2019Yeh et al, 2019;Girn et al, 2020). The relationship between divergent thinking and brain regions within the DN has been reported in several fMRI studies (Fink et al, 2010;Takeuchi et al, 2012;Gonen-Yaacovi et al, 2013;Beaty et al, 2014;Wei et al, 2014).…”

“…Increased coupling between DN and SN was observed at the beginning, followed by increased coupling between the DN and ECN. A recent fMRI study focused on product-based creative thinking in which the DN and SN attenuated with time, whereas the activity of the ventrolateral prefrontal cortex (VLPFC) within ECN increased in later stages (Yeh et al, 2019).…”
