Functional magnetic resonance imaging of divergent and convergent thinking in Big-C creativity
تصویربرداری رزونانس مغناطیسی تابعی تفکر واگرا و همگرا در خلاقیت C بزرگ-2018 The cognitive and physiological processes underlying creativity remain unclear, and very few studies to date
have attempted to identify the behavioral and brain characteristics that distinguish exceptional (“Big-C”) from
everyday (“little-c”) creativity. The Big-C Project examined functional brain responses during tasks demanding
divergent and convergent thinking in 35 Big-C Visual Artists (VIS), 41 Big-C Scientists (SCI), and 31 individuals
in a “smart comparison group” (SCG) matched to the Big-C groups on parental educational attainment and
estimated IQ. Functional MRI (fMRI) scans included two activation paradigms widely used in prior creativity
research, the Alternate Uses Task (AUT) and Remote Associates Task (RAT), to assess brain function during
divergent and convergent thinking, respectively. Task performance did not differ between groups. Functional
MRI activation in Big-C and SCG groups differed during the divergent thinking task. No differences in activation
were seen during the convergent thinking task. Big-C groups had less activation than SCG in frontal pole, right
frontal operculum, left middle frontal gyrus, and bilaterally in occipital cortex. SCI displayed lower frontal and
parietal activation relative to the SCG when generating alternate uses in the AUT, while VIS displayed lower
frontal activation than SCI and SCG when generating typical qualities (the control condition in the AUT). VIS
showed more activation in right inferior frontal gyrus and left supramarginal gyrus relative to SCI. All groups
displayed considerable overlapping activation during the RAT. The results confirm substantial overlap in
functional activation across groups, but suggest that exceptionally creative individuals may depend less on task
positive networks during tasks that demand divergent thinking.
