Creative cognition and brain network dynamics
Using network neuroscience methods, we examine brain dynamics associated with various modes of creative thought (e.g., idea generation), aiming to isolate contributions of specific cognitive processes (e.g., memory retrieval and executive control). These findings and other recent work have shown that creative thinking involves dynamic interactions between the default and executive control networks, potentially reflecting an interplay between spontaneous and controlled modes of cognition. We are currently exploring how modulating brain network dynamics with transcranial electrical stimulation (tES) impacts creative performance.

Individual differences in brain network function
In collaboration with neuroimaging labs in China and Europe, we are assessing links between personality, creative thinking ability, and brain network function. One recent study used graph theoretical analysis of resting-state fMRI data and demonstrated that openness to experience - a trait linked to creative thinking and behavior - is associated with enhanced functional connectivity within the default network, a brain system involved in mental simulation and idea production. Other research on individual differences in creative thinking has shown that highly creative people show enhanced functional coupling of the default and executive control networks. A goal for this research is to understand how variation in brain network structure and function gives rise to complex behavioral traits.

Cognitive abilities and creative thought
Another line of work in the lab examines how fundamental cognitive mechanisms - such as memory retrieval and cognitive control - contribute to creative thinking ability. Using latent variable modeling, we have assessed differential contributions of lower-order intelligence factors (e.g., broad retrieval ability; Gr) and variation in semantic memory structure to divergent thinking ability. Regarding semantic networks, we use network science methods to characterize semantic memory structure associated with creative thinking and related traits, such as openness to experience. Current work aims to extend these correlational studies with experimental paradigms that can disentangle the complex interplay of top-down and bottom-up processes underlying idea production.

Neurocognitive processes of metaphor production
We also study the cognitive and neural basis of metaphor production, a creative thought process prevalent in the arts and everyday communication. To this end, we developed a new task to assess metaphor production and examined how cognitive abilities relate to the production of novel metaphoric expressions. This research showed that metaphor production relies on specific cognitive abilities, including fluid intelligence, broad retrieval ability, and crystallized knowledge. We extended these behavioral findings with an fMRI study of metaphor production, and further examined brain network interactions supporting this ability in a follow-up study using multivariate pattern analysis (MVPA). Future work will use experimental manipulations to further isolate specific cognitive and neural processes that support the production of novel figurative language.
