Children were compensated with a ~30 USD gift voucher for completion of the study. Inclusion criteria were schoolings ystem (participants had to be enrolled in Montessori or in traditional classes from the early years on, in the case of the youngest children, or for at least 3 years), age (5-14 years of age); exclusion criteria were parental report of learning disabilities or sensory impairment. To account for variability in our measures due to nonverbal intelligence, or socioeconomic background, we controlled for between-group homogeneity in nonverbal intelligence (black and white short version of the Progressive Matrices®) and family socioeconomic status (both parents’ education levels (score from 1 to 5) and current job (score from 1 to 4); scores were summed and averaged between both parents (max 9), with higher scores denoting higher SES).

Category verbal fluency tasks have been widely used to efficiently assess semantic network organization. Consistent with traditional task administration, each child had 60s to name as many animals as he/she could. Based on previous work in children, we targeted the animal category. Children spoke their responses out loud, which were recorded (and later transcribed) by an experimenter. For each child, fluency data was preprocessed using the SemNA pipeline in R. Repetitions or variation on roots were converged and non-category members were excluded from the final analysis. Number of responses per participant were summed (total number of responses).

Divergent thinking reflects the ability to think of ideas that differ from one another; convergent thinking reflects the ability to think of a single creative solution. Performance on such creative thinking tasks has been shown to predict both academic*' and creative achievement. In the divergent thinking task, the child was asked to draw as many different drawings as possible from one imposed abstract form (i.e, incomplete shape), within 10 min. The final score was the sum of all valid drawings. In the convergent thinking task, the child had to select three different abstract forms out of eight to create an original drawing that combined them, within 15 min. Three blind judges scored the drawings for originality following the EPoC scoring manual (inter-rater agreement; Krippendorff's alpha = 0.905). Independent t tests were computed on each creativity score (divergent and convergent) to test for between-group differences. Pearson’s correlations were computed between each creativity score and the verbal fluency metrics to test whether creative thinking relates to the quantity and quality of words retrieved from semantic memory.

To control for confounding factors (such as different nodes or edges in both groups), as in previous studies, the binary response matrices only include responses that are given by at least two participants in each group. Then, to avoid the two groups including a different number of nodes, which may bias comparison of network parameters, responses in the binary matrices were equated, so that the networks of both groups in each sample are compared using the same nodes.

This approach retains the same number of edges between groups (i.e, 3n-6, where n equals the number of responses), which avoids the confound of difference network structures being due to a different number of edges, This resulted in a 68 nodes network with 198 edges for both groups.

Clustering Coefficient (CC) refers to the extent that neighbors of anode will themselves be neighbors (i.e., a neighbor is a node i that is connected through an edge to node j). Higher clustering coefficient indicates a more interconnected semantic network,Average Shortest Path Length (ASPL) refers to the average shortest number of steps (i.e,, edges) needed to traverse between any pair of nodes; the higher the ASPL, the more spread out a network is. Previous research has shown that the ASPL in semantic networks corresponds to participants’ judgments as to whether two concepts are related to each other’*. Modularity (Q) estimates how a network breaks apart (or partitions) into smaller sub-networks or communities. Q measures the extent to which the network has dense connections between nodes within a community and sparse (or few) connections between nodes indifferent communities. Thus, the higher Q, the more the network breaks apart to subcommunities. Such subcommunities can bethought of as subcategories in a semantic network (e.g, farm animals in the “animals” category). Previous research has shown that modularity in semantic networks is inversely related to a network's flexibility.
