According to the unconscious principle of creativity, inventive pondering relies upon, a minimum of, on the construction of associations in semantic reminiscence, that’s, on how the weather of our information are interconnected.
“Hence, the organization of connections in semantic memory may determine our ability to link distant concepts in novel ways and may vary across individuals. Yet, the brain mechanisms underlying the link between semantic memory organization and creativity remained to be explored,” explains Marcela Ovando-Tellez, lead writer of the examine.
These outcomes point out that real-life creativity depends on particular person variations in semantic reminiscence group that may be predicted from mind purposeful connectivity.
This analysis was executed by a gaggle of Emmanuelle Volle at Paris Brain Institute, and their collaborators, Mathias Benedek (University of Graz, Austria) and Yoed Kenett (Technion Israel Institute of Technology, Israel). The authors used a semantic relatedness judgment process, asking individuals to charge the semantic relationships between a number of pairs of phrases in the course of the fMRI acquisition.
Based on these rankings, they constructed particular person maps of pairwise semantic associations known as semantic networks. The group of semantic networks is explored utilizing network-based instruments and associated to creativity.
To consider real-life creativity, individuals have been requested to fill out a questionnaire about their inventive actions and achievements in eight completely different domains together with literature, cooking, music, sports activities, performing arts, science, and engineering.
Their outcomes present that the construction of semantic reminiscence networks predicts private real-life creativity. Participants with extra inventive actions and achievements had semantic reminiscence networks, which suggests they’re much less fragmented and extra environment friendly.
And the authors explored the purposeful connections of the mind in the course of the work and recognized particular purposeful connection patterns that predict the semantic community construction that fosters creativity, that’s, much less fragmented networks. Finally, “closing the loop”, such a singular semantic community system mediated the connection between mind connectivity and real-life creativity.
“The originality of our study is to link three levels of investigation, behavior in real-life, cognitive processes and the brain, by combining recently developed computational approaches to predict complex cognitive functions from brain connectivity and to explore individual semantic networks,” provides Emmanuelle Volle, final writer of this examine.
Altogether, these outcomes present an in-depth evaluation of a number of the particular person neurocognitive mechanisms underlying real-life inventive habits.
