Subgroups sharing similar creativity trajectories over time extracted using longitudinal TTCT-F Average Raw scores from N_behav = 48 participants. (A) Subgroups observed in the cohort. Based on how creativity scores change over time, three subgroups were found, as shown in the similarity matrix and the graph (B), which also shows the proportion of 3^rd and 4^th graders in each subgroup. (C) Shows creativity score trajectories for each subgroup, while controlling for the starting grade. The error-bar represents standard error of the mean. The creativity trajectory for subgroup 1 (CT1) shows a slump in creativity within their starting grade and a boom after transitioning to next grade, while the creativity trajectory for subgroup 2 (CT2) shows the inverse. For subgroup 3 (CT3), the creativity trajectory shows no change in creativity within starting grade and then a boom in creativity after transitioning to next grade. Asterisks (*) denote FDR-corrected p-values for the post-hoc t-tests (see ).

Mediation models H3b: Cognitive Creativity (1) and Creativity Index (2). Standardized indirect effect on: Cognitive Creativity: 0.132 (0.066) [0.013;0.273] on Creativity Index 0.113 (0.058) [0.010;0.240]. Coefficients in the upper side refers to cognitive creativity and in the lower part to creativity index. Standardized regression coefficients are presented. Numbers in parentheses refer to total effect. *p < 0.05, ^**p < 0.01, ^***p < 0.001.

Association between FNC and the creativity scores. Regarding visual creativity, significant and positive associations were found between figural creativity scores and functional connectivity between the left FPN and pDMN (P = 0.002, q[FDR] = 0.05), and marginally significant associations and functional connectivity were found between the right and left FPN (P = 0.026). Regarding verbal creativity, positive and marginally significant associations between verbal creativity scores and functional connectivity between the right FPN and aDMN and between the DAN and MN was found.

Identifying neural correlates of creativity trajectories. (A) Shows preserved trajectory of creativity scores for each of the three profiles in a smaller cohort of N_fNIRS = 26 with fNIRS data at all three time points (as compared to the larger cohort of N_behav = 48). (B) Significant creativity trajectory x time interactions were observed for the mean (across all regions) B_T scores during creativity drawing assessments. (C) Shows post-hoc analysis to reveal the brain regions driving the creativity trajectory x time interaction observed during creativity and control assessment conditions, respectively. Blue circles denote individual channels driving significant interactions (p<0.05).
