Even though the discriminability of individuals’ task performance is not significantly different within each dataset, i.e., there is no significant difference between the correlations (ABCD = gold, r = 0.19, ρ = 0.15, ps < 0.001; HCP = violet, r = 0.17, ρ = 0.12, ps < 0.001; difference between rs is not significant Z = 0.46, p = 0.456), the mean performance and mean network strength are both significantly larger in adults. Overall, adults show stronger SA networks and better 0-back performance than youth (red + signs show the mean of SA strength and 0-back accuracy for the scatterplots in each dataset).
