Résumé
Creativity is a complex construct that lies at the core of what has made human civilizations possible. One frequently used measure of creativity is the Abbreviated Torrance Test for Adults that yields an overall creativity score. In this study, we examine the relationship between the task-related differences in brain functional connectivity and the creativity score in a male and female group of participants. Brain functional connectivity was estimated from the steady-state visual evoked potential (SSVEP) event-related partial coherence in a group of 27 females and 27 males while they performed a low-demand visual vigilance task and the A-X version of the Continuous Performance Task. Task-related differences in brain functional connectivity (ΔFC) were correlated with the creativity score separately in the female and male groups. We found that the creativity score was correlated with a parieto-frontal ΔFC component for both the female and male groups. However, significant gender differences were observed in both the timing and the laterality of the parietal component. Females exhibited a left parietal to bilateral frontal ΔFC component correlated with creativity score and this peaked on the appearance of a target in both tasks. By contrast, males demonstrated a right parietal to bilateral frontal ΔFC component correlated with creativity score which peaked on the appearance of the letter following the targets. These findings are discussed in the context of the role of the Default Mode Network in creativity, and the role of gender-related differences in cortical networks that mediate creativity.
