Abstract
How do creative ideas arise? A common assumption is that ideas result from searching and combining semantic memory knowledge. However, the mechanisms acting on memory to yield creative ideas are not elucidated. This study explores the neurocognitive correlates of semantic search components related to creative abilities. We designed an associative fluency task based on polysemous words. We distinguished two search components by assessing clustering and switching performance from the responses within and between the different meanings. We related these components to creativity, executive abilities, and semantic memory structure explored with semantic networks methods, and identified their predictive functional brain connectivity patterns using connectome-based modeling. Clustering correlated with divergent thinking, while switching correlated with the ability to combine remote associates. Furthermore, switching correlated with semantic memory structure and executive abilities, and was predicted by connectivity between and within the default, control, and salience networks. These results suggest that switching captures interactions between memory structure and control processes guiding the search. In contrast, clustering relied on interactions between control, salience, and attentional networks. Clustering may capture controlled processes related to persistent search. These findings shed new light on the neurocognitive mechanisms allowing an efficient and flexible semantic search to support creativity.
